Homemade irrigation devices with a timer. Installing a timer for automatic watering in the greenhouse

Each plant in the greenhouse requires moisture, heat and sunlight. However, periodically water all planted seedlings, especially in large greenhouses, is hard.

Modern technologies do not stand still. System of automatic irrigation was invented specifically for dacnons.

There is an opportunity to buy it in the store or make it yourself.

Types of automatic polishes

1. Rain watering. It is intended for watering the landing on top through a micro-coating device with spray nozzles. The minus of this system lies in the fact that there are moisture on plants. Therefore, after rain irrigation, they need to shake them. How the process of watering is carried out: the hose connected to the sprayer splashes water. IN building stores There are raincoats with a more complex device, but they provide a more reliable and uniform spraying.
2. Intravenous watering is suitable in order to irrigate more arrogant shrubs. It is performed using a porous hose and tube.
3. Automatic watering It is considered the most profitable compared with previous two species. In the process, water passes only in the zone of the root system. Watering hoses can be on the surface of the Earth and inside it. In addition, the bushes are optimally protected from frosts due to wet soil. Drip watering well suited to those greenhouses where there is no place for large number water.

Automatic watering system with your own hands

Insufficiently jifted old hose to build a good drip watering for the greenhouse. First you need to create required pressure Inside the watering system, so that watering throughout the hose passed the same. Sequence of creating self-watering for bushes in greenhouses:

1. A wooden horizontal support (1 m above the ground) is constructed above the polished bed.
2. Plastic bottles of 1.5 liters are fixed on this support, each need to drill a hole at the bottom.
3. A needle with a medical drip is inserted into the holes.
4. Water is recruited in the bottle. When filling bottles, the factor is taken into account that all drops will leave the medical dropper equally.

Tools and materials that will be needed to install the watering system:

• hose;
• filters;
• shovel;
• water tank
• trumpet;
• medical dropper;
• plan of the site.

Automatic irrigation system - what is it?

Almost every store building materials It is possible to purchase a ready-made irrigation system.

In addition to the special components intended for watering, it contains a timer that sets a certain time for watering with accurate water. The system is automated, has its own pump. Using this system Watering plants, no need to worry about the fact that the soil can wound.

Princes of watering in a greenhouse with a timer

It is not necessary to buy an expensive watering system when it can be built with your own hands. You only need to buy plants and filters for cleaning. What phased process Installation automatic watering?

1. Preparation. First draws the plan garden plotwhere the beds or greenhouses are indicated for watering. Carefully think over the placement of pipelines in the garden, constipation reinforcements, hoses. If the garden is located on the slope, the pipes are better to install horizontally, and the hoses with a slope.
2. The scheme marks places where the pipes are connected. It is necessary for right calculation branches, plugs, connectors. Pipes buy only plastic, as they are very light, do not rust, durable, inexpensive.
3. Install the water container. To do this, take a barrel of large sizes, positioning it at an altitude of 2 m above the place where the drip watering will be. Then this barrel is connected to a total water supply.
4. Laying the hose and pipes. From the barrels we are making a pipe, 25-30 mm thick. Hoses and pipes can be installed either on the surface of the Earth, or under it, or above it is in suspended state.
5. Counting a drip ribbon. Here you need to understand how many in the greenhouse there will be a row with planted plants, which in the future will need to water. Then under these beds put the ribbon. For example, if the rows are 20, each of which stretches for 10 meters, it will take more than 200 meters of tape (including stock). To the drip tape is durable, it is installed with light cleaning filters.
6. Installation of the starter. To do this, drill in the pipe hole with a diameter of 15 mm. After they insert compacted gum, then starters. As a result, at the end of each row will have to trim a 5 cm drip tape, then the tip of twisted and put the cut edge on it.

Many owners spendaty great amount time to watering, spending large quantity Waters than need to plants. Especially problematic producing regular watering remote from home and fields.

It was for such purposes a special timer Watering, we will talk about in this article. We'll figure it out how the device works, for which it is used, whether the price corresponds to really benefit.

What is it and how does it work?

Let's start with what is a timer of automatic irrigation.

Design can be different shapesHowever, most often it resembles a meter for water that everyone has in a private house or apartment. The device is designed for watering for watering at a certain time, which is specified by the timer and for the programming of waterings for every day of the week.

At the same time, the program is not limited to anything and, if you deal with the action system, you can program separate option watering for every day, while putting different time and duration.

That is, we have a device that allows you to remotely irrigate the program you specified. There is a fixture on batteries that are protected from moisture. Thus, the timer does not depend on the presence of a power grid on, therefore, even in the open field can be applied.

Important! When changing the batteries, the specified programs are saved.

The timer works as stop valvewhich on the one hand is connected to the pipe to which water is supplied, and on the other hand, an ordinary wrapping hose is attached. Construction provides nozzles for watering hoseTherefore, it is not necessary to buy anything to buy anything. At the moment when you need to produce, the device opens the valve, by type ball craneAnd there is a water supply to the irrigation of the plot.

It is worth noting that not all waste timers have a software that will allow programming actions, so be sure to specify the possibilities of the device when purchasing. Also note that the timer for watering, although it has a similar shape, but does not perform the function of the water meter.

Types of devices

Mechanical

The mechanical timer has a clock device that was used in the first microwave ovens or mechanical clock. The hourly device operates on the spring and can provide a continuous watering to one day. At the same time, any adjustments are made manually. Such devices are deprived of the dial or screen, as well as programming capabilities.
The mechanical timer is excellent for household plots, where irrigation is constantly monitored by the owner. At the same time, the unit allows the supply of water a fixed amount of time, after which the mechanism is triggered and the crane overlaps the water supply.

Did you know? The first prototype of the timer and the stopwatch was invented invented in 1720. The device could fix the time intervals up to 1/16 seconds.

Electronic

Electronic option as you might guess, has additional feature Programming that allows you to spend more time for other affairs than behind irrigation of vegetation. Such options are best suited for areas remote from the house. Since some cultures require daily irrigation, the acquisition of such a timer will pay off almost instantly, given the cost of gasoline and the cost of time.
The electronic version has two varieties that we further characterize.

The electronic watering timer makes it possible to set actions for one week, while the maximum watering duration is 2 hours. All tasks are set in advance by a person, after which the system works on a specified scenario.

Such devices have mid-price And a fairly good functionality, which allows remote irrigation.

The most advanced option that has up to 16 programs. Any action associated with irrigation is set. Also you can irrigate from one timer various plantsWhen setting up a certain watering time for everyone.

To make it easier to understand what the difference is, we compare the cheapest microwave and microwave with all possible "frills". Yes, each of them can warm up or cook, but a more expensive version gives you a bigger choice, which allows you to prepare an absolutely any dish using only a microwave oven that will replace the oven, grill, gas stove, and even.

Also with electronic timers with software control. They allow you to irrigate all cultures at once, using your time and its volume of water for each of them. Such a system works without any interference from the person.

Did you know? The first electronic watches appeared in 1971. They were equipped with digital indication on LEDs.

Choice rules

To begin with, it is necessary to determine what you need, since it will be driving the functionality of the device and, of course, its price.

If you read this article, then you are interested in this device, or there was a need for a similar sensor. Therefore, it is worth considering all the options, as well as explain their utility in one way or another.

• Mechanical option. If you do not want to stand "batched an hour" with a hose in your hands on the household plot, as well as memorize exact time Watering, then enough to purchase the easiest option that works on the spring. You will receive a device that does not require electricity, does not deteriorate from the impact of moisture or the sun, and also has a low cost.
• Electronic version with mechanical control. Such a device is installed on the site remote from the house and is designed for irrigating one culture, as you can programmatically set any time for any day of the week. Of course, such a device is more expensive, however, it is suitable for watering large fields as it is impossible, since its functional is quite enough. It makes sense to establish a similar device on the household plot, because the main advantage of the device is distant workwhich saves you time.
• Electronic version with software control. Such a device, usually put in greenhouses, where not only irrigation schedule is important, but also air humidity. The presence of sensors allows you to control the humidity of the air, as well as to set the ideal program for each culture.

Important! If the device works on batteries, then they are, on average, enough for 1500 inclusions / shutdowns.

Use the most advanced option in open fields does not make sense, since the entire functionality of the device will not be disclosed. And given the cost of the apparatus, his loss or breakage can hardly hit the pocket. After all, it is worth understanding that the larger the device electronic stageTheover it is more vulnerable to external factors.

Now it is worth talking about what device to take for plumbing systemAnd what timer for watering to choose for samotane systems.

Let's start with the fact that these timers are distinguished by the mechanism of opening and overlapping water supply. In one case, a solenoid valve is used, and in the other - a ball valve. The solenoid valve opens only under pressure of at least 0.2 atmospheres. Used for centralized water pipes, as it is withstanding a large pressure. Also, such a valve protects against air supply during when the water is disabled.

Used for samotane systems, that is, for irrigation from any capacity (barrel). This option is better suitable for watering greenhouses and greenhouses, as a fixed amount of water is used. Perfect for drip irrigation systems. Works at a pressure of 0 to 6 atmospheres.

Number of valves. Above, we wrote that advanced timers allow you to set the script of watering for different cultures. In order to do this, you need to purchase a device with multiple valves. At the same time, a separate time and duration of watering for each plant are specified. Use several valves is useful in greenhouse, as it is important to constantly maintain a microclimate to get a good harvest.
It is worth noting that several valves can be put on the simplest mechanisms, but due to this, their functionality does not increase. You just can not do so that, for example, a mechanical timer watered at first one culture, and then another, since all actions are set manually.

Additional features. Rain sensor, an additional filter, as well as a mini-pump can be connected to electronic options.

The rain sensor, as you already understood, is used to ensure that our timer does not block the plot at the moment when it rains. An additional filter is used only for drip irrigation to eliminate the clogging of the system. The mini-pump is needed in the case when the water supply is made from the tank, and the pressure is 0 atmospheres.

How to connect and use the device

After the connection, we begin to deal with the principle of work. The simplest timers are enough to "start" as a clock, after which the water supply will begin. Complex options have multitasking, which is why the instructions require full study.

Build device

After printing the factory package, carefully read the instructions. Also pay attention to what way the water supply arrows show. If you ignore this aspect, then you mounted the device on the contrary.
After reading the instruction in which the installation principle is detailed, go to the system connection. Start by comparing the pipe diameter at the entrance. Most likely, you will need to separately buy an adapter, which will allow you to connect the hose of any diameter to the device.

After you picked up everything you need, you need to connect the pipe to the input. To do this, remove the protective ring, we put on the pipe on the "spout" and tighten the ring that must be fixed. Next, we look at the output diameter. Most often, the timers are a special nozzle, which is used to connect precisely watering hoses. If the diameter is suitable, then just plan the hose if not - we buy the nozzle of the desired diameter. After connecting the hose to the output, the installation of a simple timer is over. To mount advanced devices for drip irrigation, additional actions are required, which can also be set forth in the instructions. Depending on the irrigation system, which you can use additional adapters, sleeves or tees.

Setting Timer

After connecting the device to the system, you need to insert batteries or connect to the network (some timers support only the connection to the electrical outlet). Next will light up the dial, under which the buttons are located. Most devices have two buttons to increase or decrease numeric value, button, exposing a day or month, as well as the device on / off buttons. There is a "Start" button, which starts the actions algorithm.

Depending on the configuration and manufacturer, the number of buttons and the action for which they respond can be varied, so we led the general data.

To configure the timer it needs to be turned on. Next set current right timewhere the device will navigate. Next you need to create a script for every day. To do this, choose the day, after which I first exhibit the time of watering, and then its duration. After that, switch to other days. If you have an advanced version, then it makes it possible to create a script for a whole year. This feature is ideal for.

After a complete setup, click the "Enable" or "Start" button, and the unit will begin to execute the script.

Important! Electronic timers do not have an initial setup, so everything is programmed manually under personal needs.

Features of operation

Now let's talk about how to properly operate the device so that it lasts longer.

Let's start with the fact that only high-quality batteries should be used if you have electronic device. At the same time, the batteries should be 1.5 V, or another voltage, if described in the instructions.
As for the water, which is fed to the device, it should be clean, fresh. Any heavy particles will score a filter, because of which the device will have to be cleaned often. At the same time, the quality and strength of water supply will be reduced at times. Also remember that the water temperature that passes through the device should not be higher than +40 ° C.

Automatic irrigation systems are designed to rescue the dacket attending their site once a week and on the weekend. Meanwhile, hot summer days are required by watering if not daily, then at least once every 2-3 days. For a week, the land dries very strongly and even short rains do not always get out of the summer house. And it would be good if "someone" watched your plants somewhere in the middle of the week, on Wednesday, Thursday, for example. This is "someone" and is - a system of autopolivation.

IN homemade devices Automatic irrigation It is convenient to use mechanical or water timers to control cranes feeding water to watering. This avoids the use of any electronics and electricity at all and make the system absolutely non-volatile. (). The easiest way to make a water timer, in which time is "practiced" in the form of drops. Water, gradually emerging from the Ballast Capacity, makes it easier and after a while its weight is missing, so that it would keep the crane handle, including watering.

But how exactly rightly noticed one of the readers, organize a water timer of a drip type with a really high exposure is not so simple.

I made additional research in this problem myself was convinced of this. How I did not try to minimize the diameter of the hole in plastic bottle (Using a sewing needle), water flowed quite quickly. Moreover, its flow rate depended on the height of the water column. When the bottle was complete, water flowed in a trickle. Then he passed into the drops and only when the bottle was almost empty, the droplets became slow. Such unevenness itself is not terrible, since we are important only the final time of the timer. But it turned out to be very small. And difficult to be projected. Imagine how much water and time need to be launched a timer for 3 days?

Continuing to experiment, I replaced the round hole in the slotted bottle. Those. took acute knife With a thin blade and made an open-length 1-1.5 cm. The water through this slit was already so much slower than through the puncture of the needle. And although the unevenness of the speed drops still remained (and hence the difficulty of debugging in time), the time of the timer was significantly increased (from 2-3 hours to 10-12 per 1,5-liter bottle).

But left one more an important flaw. Such drip systems require not just clean water, and crystal clear. The slightest Sorinka or insect in the water can bring the timer in order by closing their bodies "ambrusura". The probability of this makes the entire system unreliable and I decided to abandon her at all. Although, of course, you can install and in front of the slit of some kind of fairly large foam rubber filter, mineral Wat. etc.

Therefore, I decided to make a timer deprived of all these flaws. Timer who would not be afraid dirty waterNor insects, and even tracked precipitation. If it happened to rain and the need for watering disappeared or moved to 1-2 days, then the timer was to "work out" and also to transfer the time of operation for a while, and the proportional to the amount of precipitation dropped. And both of these tasks managed to solve, and in 2 versions.

Water timer using evaporation.

"Mechanism" of drying linen is known to everyone. Water molecules leave the surface of the fabric and fly away, the cloth dries. But if you organize the "delivery" of the new water into the fabric, then it simply becomes a large surface for evaporation of water. And the delivery is easiest to organize, setting up a large "wick" from thick fabric. They especially show the effect of capillary suction of water into the fabric. Actually, there is a towel and towels ... And if one end of a thick towel is omitted in a bucket of water, then the towel firstly sprinkles the water "how much will fit", and secondly, it will never dry until all the water from the bucket is evaporated.

I spent a small experiment. I poured about 5 liters of water in the pelvis, installed a small design of the grid in it (to raise the towel over the pelvis and increase the area of \u200b\u200bevaporation). Covered with a wet towel. 5 liters of water was enough for about three days. This timer is not terrible or dirty water, nor insects, evaporation occurs depending on temperature, wind, humidity, etc. Atmospheric precipitates will automatically replenish the water supply and transfer the water time. Those. It is the situation that characterizes the degree of need for watering.

The design of such a timer - ballast is completely obvious. This is a container, with a P-shaped frame installed in it, on which the fabric forming the "sail" is the evaporator. The only drawback is the complexity of debugging. It will be necessary to spend several experiments, for example - how long will 1-2 liters of water evaporate? Well, then and then count the time delaying time of the irrigation system.

Water timer with chipper-wick.

Another variant of the water timer is a wick dropper. In principle, the phytyl also uses the effect of capillaries. Then the water does not evaporate and just flows. If you lower the wick to the water container (for example, a twisted harness from any matter), or just a thick rope, then water along this fit will be climbing up to a certain height. And if the wick is transferred through the edge of the tank, the water will start dripping from the free end of the wick. The speed of the drop is controlled and the design of the wick itself (material, thickness, etc.), and the religion of the phytyl (for example, a wire loop).

The height of the water column does not greatly affect the speed of the drop, but whatever water rose through the edge of the capacity, and the water level was more or less permanent, and the water supply was significant, the design of the wick timer should be approximately such (see Figure). In the capacity of a minor depth (5-8 cm) a bottle of water reserve is installed (5-10 liters). The bottle below the water leakage hole is made. The cover of the bottle is closed, naturally hermetically. Fill the bottle with water, closing the hole with your finger and put in the "brother". Part of the water from the bottle follows, but only to the level when the hole is under water. Subsequently, as water consumed, water from the bottle will compensate for the loss.

The big plus such a timer is that it works very consistently for the entire time, since the water level in the "KORITS" is always the same. And it happens to rain - he will simply replenish the supply of water in the timer (brother) and water from the bottle will not be spent. The timer is also not afraid of dirty water, insects, etc. Fitil "takes" only clean water.

A simple experiment conducted by me proved the absolute efficiency of such a timer. 5-T. lithon bottle With enough intense drops (1 drop of about 2 seconds) was enough for 18-20 hours of operation. Of course, adjusting the intensity of the drops and increasing the capacity of the bottle can be achieved and multiplying delays. It was important for me only to check the principal performance.

The undoubted advantage of such a timer is also the fact that it can perform the function and humidifier in the greenhouse. To do this, you need to organize droplets on a rotating disk (for example, so).

Moreover, such a drop can replace both the automatic watering system itself, if you organize a drip watering of plants! The cost of such a drop is equal to the value of empty PET bottles of water, or plastic canisterAnd nothing bothers to arrange them at least under each plant. And you can make one big container and dilute philitis under the roots of plants. And then lovers drip watering We experience some difficulties with expensive hoses - ribbons for drip irrigation, clouds in them, etc. can come in handy in hydroponic systems.

As you can see, the designs of the "long-playing" water timers are very simple, and they themselves are very reliable in their work. Therefore, to make an automatic watering system on its plot maybe each.

Last spring, planning to automate irrigated lawns near the house, hit Ali express, and found this timer. I had experience using such timers only purchased in Poland. This one, in contrast to Polish, has as many as sixteen programs. (Polish is only two of them). That is, you can put your watering 16 times a day !!! ... This is, of course, the option, because, in practice, mostly needed only twice.
I personally use only two programs - that is, I insist the timer so that watering happened 2 times a day - at 0.30 and in 5.30. At this time, "rain" does not interfere with anyone. In addition, plants at this time "cooled" and do not receive temperature shock.
The manufacturer is provided at the output of the hose connection, for this in the kit there is a quick-release connector.

But I, for example, set a timer into a pipe break, which comes from hydrofra to sprayers.
It feeds the timer from the two elements of AAA. If you put "Dosel", grabs for the whole season. No wires do not have to pull it.
I used it one season, and in the winter I bought two more such - for the automation of drip watering greenhouses and beds.

Watering is one of the most important conditions for growing and fruiting gardening crops. This is especially brightly expressed in the conditions of a minor winter and subsequent arid summer, because many people have no permanent opportunity to monitor the process of watering their pricework. Excellent solution will be an electronic irrigation controller, which, following the program laid in it and relying on external factorsSelf will make the process of irrigation.

The easiest way to get a beautiful lawn in front of the house

You, of course, saw the perfect lawn in the cinema, on the Alley, and perhaps on the neighboring lawn. Those who at least once tried to grow a green platform in their own area, without doubt they will say that this is a huge work. Lawn requires careful landing, care, fertilizer, watering. However, only inexperienced gardeners think so, professionals have long known about the innovative agent - liquid lawn Aquagrazz.

Currently, there are several classifications of the watering controller, all of them, as well as types of timers, are listed below.

Classification of control facilities

• Auto. A similar type of controller allows watering according to a given program. Also, with the help of it, you can adjust the amount of water during drip irrigation. A similar controller is most practical for greenhouses. The undoubted advantage is the possibility of programming on optimal mode glaze. Bright example Watering controller is popular in our country S538. No less popular ball GA 322;

• Hand timer. In it, to supply water and control over its distribution, it is necessary to look after. That is why such timers gradually go into the past, giving way to an automatic controller.

Classification of controllers at the place of use

There are timers for watering the following sites of the estate:

1. Garden. For the garden are designed different kinds controllers. Here you can use: electronic, mechanical, automatic, ball and other types. Such controllers can be used in water fence from both the water supply system and from the barrel. An excellent model for the garden is the GA 322 or Ga 319 ball controller.
2. Garden. For the irrigation of the soil on the garden, it is customary to use a mechanical or electronic timer. An excellent solution will be the model Palisad 66191, which has more than 15 watering programs. This allows you to exhibit the necessary conditions Water supply for beds with different cultures.
3. Greenhouse. As a rule, plants landed in greenhouse require drip irrigation. For these purposes, the Palisad 66191 mentioned above is also perfect. In its functions there is also a drip irrigation program.

Classification of water supply

There are several types of controllers that are classified according to the type of water supply.

1. Timer of drip irrigation. At the moment are perhaps the most popular among their fellows. The drip irrigation controller eliminates the possibility of overpowering water and excess soil moisturizing. Irrigation occurs in accordance with a predetermined water supply scheme. The advantage of drip irrigation is slow water supply. With this irrigation, the plants grow more versal. Also, in addition to moisture, you can supply various additives that are necessary plants. An example of such watering controllers are not essential to us Palisad 66191, Ga 322, Ga 319, as well as Raco of various modifications. On controllers of irrigation systems of this type there is a humidity sensor that is capable of capturing the state of the soil and the presence of precipitation. If the soil is without that wet or rain, it is determined by the humidity sensor and the water supply is not performed.
2. Ball controller irrigation. Two types are available: mechanical and electronic.

The advantage of the mechanical timer is the ease of operation. Before it starts, it is necessary to set the time frame of the soil irrigation and the water supply duration.

The electronic must be programmed to the date, time, as well as to install the necessary program that is most suitable for a specific culture. Water supply occurs with a pressure that creates a pump. The pump can take water from both the crane and from the reservoir or barrel. A vivid example of such a controller is Palisad 66191.

The most popular irrigation controllers

5. Cost varies from 800 to 3000 rubles. 800 rubles is a mechanical watering controller, 3000 rubles, respectively, electronic.

Additional Timer Functions

In addition to its main purpose, the following additional features:

1. Rain sensor. A similar device is installed when installing soil irrigation systems in open areas. It captures the presence of precipitation in an amount of from 3 and to 30 millimeters. Watering scheme, respectively, changes, that is, the mini sensor will not make moisturizing during natural precipitation. Also on a similar sensor there is a delay timer that is installed in manual mode. Water supply faucet will be blocked after the rain at the time you will specify.
2. Membrane pump. This device is mounted along with the timer or separately. It monitors the amount of water accumulated in the container, and when the critical mark is reached, turns off the feed.
3. Soil humidity sensor. Such devices are installed in several places in the garden. They measure soil moisture indicators. When a certain level is reached, the sensors send a signal to the controller, which in turn opens the crane. The humidity sensor is an indispensable device for irrigation systems in the event that there are no constant observation by man. The humidity controller allows you to maximize the cost of water, because the water supply system crane opens only in those moments when it really needs. When installing such a device, the irrigation scheme must be changed, as a rule, in watering controllers, the sixteenth program is designed to work with humidity sensors.
4. Filter. It serves to further purify water, if water for watering is taken from natural reservoirs or septic systems.

Everything additional devices You can purchase with a watering controller or individually. It will be much cheaper with the purchase of all equipment for mounting irrigation systems.

Design controller with your own hands

If for any reason you do not want to purchase in the store, you can make it with your own hands. There are many methods of assembling timer with their own hands, the most popular of them are listed below.

The simplest controller watering

The simplest watering controller is easy to make it yourself. For this you will not need any other knowledge. All that is needed is fiber like that that is used in kerosene lamps, And the tank with the height of 5-10 centimeters. The scheme of work is very simple. The fiber is one end falls on the bottom of the tank. After it is completely soaked, water will be dripped from the other end. It must be placed on a plant that needs watering. Thus, the level of humidity will be maintained. If a more abundant irrigation is needed, you need to take a thicker fiber.

Also, the device of drip irrigation can be built with their own hands from an ordinary medical dropper, the principle of which is known to each person.

Device adjusting ball valve

For manufacture with your own hands you will need the following materials And products:

• water tank;
• crane;
• plywood circle - 2 pieces;
• five-liter bottle;
• mounting glue;
• sewing threads.

To mount the watering controller, the crane must be modified a little. Instead of the handle of closing and opening the crane, you must install the pulley.

1. The pulley is made of two plywood circles. They glue with glue. A sewing thread is wound on the pulley so that the design is reliable, it is necessary to make several revolutions.
2. To the second end of the cord, it is necessary to bind the balance and compensator of its weight, that is, the water container. The weight of the cargo must be chosen so that it is enough for the crane becomes a lever.
3. Adjust the weight of the cargo is very simple. To do this, it is necessary to add the necessary components into a bottle with water and sand to a bottle with water and sand.
4. Severity compensator, i.e. water bottle. To do this, in her day it is necessary to do a small hole. When the mass of the compensator decreases, the cargo starts to drag the pulley rocker on itself, thanks to this, the crane will open.

It can be connected both to a tank with water with a tap equipped on it and to the water supply system. In the case of a capacity, its level should exceed the surface of the Earth with planted plants requiring watering.

In the case of a water supply, everything is a bit simpler. Nevertheless, the location of the water supply line should be higher than the level of land at least 1.5-2 meters. Otherwise, the ballast and the timer container will not be able to function due to lack of space for maneuver.

Arrangement of electric timer

In order to make an electric timer with their own hands, you need to possess initial knowledge In the field of electricians.

All that we need is: an electric motor, pulley and photocells.

• Instead of the handle of the crane, it is necessary to install the pulley;
• Through the belt it must be combined with the plot of an electric motor installed in close proximity;

• The inclusion of the motor will occur depending on the movement of the Sun, it is for this that you need photocells that should be adjusted for the movement of the Sun or any other factor. You can also install a timer on the circuit breaker, which will run it at a certain time to open the water supply. And to another - for closing, that is, the reverse engine operation will be performed.
• In no case cannot use a powerful motor that is powered by the power line. An excellent solution will be the motor of the screwdriver, and in some cases, even from toy typewriter. It all depends on how tight the crane opens and closes.

The latter option is the most optimal in all indicators, because it is possible to adjust the water supply for the watering line in necessary volumes And for a pretty long time, in contrast to the second option.
