Your incessant inner dispute is to plunge into life or be above it. Your experience and discernment combine to create a sage. Your experiments are difficult and dangerous, but they bring you insight. You become an example and an expert. In the end, your inner daredevil simply refuses to further participate in this circus, which is why the dome of the circus immediately turns into a green hill - the favorite refuge of sages and prophets. A soldier grows up to a commander, a worker to a manager, an actor to a director. The Profile 3/6 representative demands respect for himself. He comes to people with the position "I was there, I saw everything, I can tell you." For him, life is an eternal school. He comes to her as a student, and ends up as a director. Agree to any experiments. Your Sixth Line is a guarantee that you will get out of them alive and take with you a piece of knowledge and experience.
Unlike 3/3, Profile 3/6 can look forward to the end of the chaos. Most 3/6 mature three times. At 18, 30 and 50 years old. The tomboy teenager breaks out of puberty and comes into adulthood already loaded with certain obligations. If the load is insufficient, he remains a tomboy for up to 30 years. By this age, the number of scars is optimal. Whatever happens next, by age 50, Profile 3/6 is at least a worthy role model.
At 50, you rise above the chaos of life and begin to feel like an observer. You are the smartest and most trusted person you know. Your contribution can have a significant impact on any business. The sixth line is capable of insights. She gives the Third a vision of perspective. This saves the Third Line from the breakthrough tactics inherent in it in life. You are a real value that cannot be overestimated.
In dealing with people, you are decisive and original. This is softened a little by the inherent sense of humor in the Third Line. You are fascinating to the point of admiration. You make a deep impression with your mind and attitude towards life. I am ready to advise others to just find you and talk. It's worth it.
The Third Line aspect that does not bear any obligation cannot be avoided. The need to know where the fire exit is, it is better to back up the knowledge of where is the mountain where you can hide from the flood. But the Sixth line knows how to control. She perfectly understands the inadmissibility of escaping until the moment when an angry roast cock is behind your back.
The 3/6 profile controls the internal balance. The more he gets smarter, the better he manages. Therefore, it is important for you to learn to climb only in those situations that resonate with you internally. The inevitable period of bounces that you go through teaches you to be good at recognizing what is worth doing and what is not.
If you get the feeling that you are stuck, it means that you have come off the top in the wrong direction, in the wrong situation and in the wrong people.
The 3/6 profile is always on the path to great wisdom, but it is not easy to complete this path. However, your high destiny does not allow you to deviate from the path. You enjoy the process of determining the direction. Eventually people will start coming to you. They will ask you for advice, and you, depicting an ironic smile on your face, say: "So, my friend, where do we start?"
Relationship with 3/6
Profile 3/6 partners are pretty darn attractive. They always have someone to choose from, and they know how to do it. They seem wise beyond their years. But when it comes to plunging into the chaos of real life, they are shy and worried. Therefore, no matter how smart, knowledgeable and experienced they may seem, they always need a separate personal space in which they can take a break from the need to seem. Don't ever forget about it. Do not think that the tall hill of the sage alone can replace this space. The man on the hill is too visible from all directions. Profile 3/6 feels its body as a cage, into which it is stubbornly pushed by reality. They are free-spirited and independent by nature. And they need to be perceived in this way. If you try to change anything in them, they will simply run away. More than anything, they are afraid of straitjackets. Give them as much space as they need. And they need a lot.
Treat their personal freedom with due respect and understanding. In return, you will receive reciprocity and loyalty. There is no obstacle that you cannot overcome hand in hand. Over time, your partner realizes that his main mission is not to dream, but to make dreams come true. A strong alliance and a reliable ally make this mission feasible. Use his faith in yourself and enjoy the view from the window of the racing car.
Compatibility
Perfect compatibility with representatives of Profiles 3/6 and 6/3 like you; it is also easy for you to interact with 1/3 and 3/5.
The cultivation of cereal crops, in all countries and at all times, has been assigned a special role. Cereals form the basis of not only our diet, but also are the main forage base for animal husbandry. So in the agricultural equipment market, grain seeders are in great demand.
The choice of such equipment is huge, domestic and foreign companies, competing with each other, offer both simple, inexpensive units and powerful, multifunctional seeding complexes.
In our story, we will talk about the SZ-3.6 grain-fertilizer seeder, developed back in the 70s at the Krasnaya Zvezda plant. The unit was designed to work with legumes and grain crops, as well as the simultaneous application of mineral fertilizers in granular form. SZ-3.6 coped with the assigned tasks perfectly, which earned it the widest distribution throughout the USSR, and after Russia and the CIS countries.
The history of the creation of the SZ-3.6 seeder
The history of the Krasnaya Zvezda plant began at the end of the 19th century, or rather in 1874, when two English brothers, Robert and Thomas Elvorti, opened a workshop for assembling horse seeders in Elisovetgrad (modern Kirovograd).
In the following years, the workshop developed into one of the largest manufacturers of agricultural equipment in Europe. By the end of 1917, more than 7 thousand people worked in production. After the October Revolution, in 1919, the plant was nationalized. By 1925, the production of seeders in comparison with 1913 increased 2.5 times. In the late 1920s, the plant's products were exported to the Middle East.
In 1929, the enterprise mastered the country's first tractor, grain seeder T-1. This model was awarded a gold medal at the international exhibition in Libau. And in 1937 its modification, the T-7 seeder, took the "Grand Prix" at an exhibition in Paris.
With the beginning of the Great Patriotic War, the plant was evacuated to the Penza region. There, in harsh conditions, in dugouts and unfinished areas of the sugar factory, the production of ammunition began.
After the liberation of Kirovograd in 1944, the restoration of the 84% destroyed plant began. In 1945, 1500 seeders were already produced, and in 1950 the production level exceeded the military level. 45 types of seeding machines were developed and put into series, already in the first decade after the end of the war. In 1955, the plant already produced 78 thousand agricultural machines a year.
Since the end of the 60s, the plant has been significantly expanded, a significant re-equipment has been taking place. This allows the company to update its model range, and a more modern grain-fertilizer seeder SZ-3.6 appears.
By the beginning of the 90s, the enterprise has the capacity to produce 100 seeders per year. After the collapse of the USSR, in 1993, the company was reorganized into OJSC Krasnaya Zvezda. In 2003 the plant received the Ukrainian name "Chervona Zirka".
Today it is the largest company in Eastern Europe and the CIS countries specializing in the production of seeding equipment.

SZ-3.6 seeder device
The main structural elements of the grain seeder SZ-3.6 are the following units and parts:
- The frame is welded, with a footboard and a device for coupling with a tractor;
- Two pneumatic support-drive wheels;
- Two boxes of grain crops with separate sections for fertilizers and seeds;
- 24 reel-and-grooved seed dispensers, and the same number of reel-and-pin fertilizer dispensers;
- Seed tubes, rubber, corrugated;
- Double-disc coulters and finger harrowers.
Each of the openers by means of a hinge is connected by a leash to the frame, or rather to the opener bar, and through a spring-loaded pressure fork and a bar - to the round and square shafts of the lifting mechanism and the mechanism for general regulation of the depth of the openers.
The shaft of the harvesters has a square section and is connected with the lifting mechanism of the openers, powered by a hydraulic cylinder, by means of a spring-loaded bar and a lever. Sometimes, instead of harvesters, and more often at the same time, loops of chains are installed.
A toothed-chain drive and a shaft with an uncoupler and overtaking couplings transmit torque from the support wheels to the shafts of the seeding devices. Overrunning clutches transfer rotation from both wheels to the devices, and an uncoupler serves to disengage the gear during the lifting of the openers.
To control the rotation of the seeding units, the working depth of the openers, the communication between the tractor driver and the seeder, an alarm and control device is installed on the SZ-3.6 seeder. The signaling device from the electrical system of the tractor is working.
The principle of operation of the SZ-3.6 seeder
Granular mineral fertilizers and seeds, from the respective compartments, are rolled into chambers with seeding devices. When the seeder moves in working mode with buried openers, the coils of the seeding machines, both fertilizers and grain devices, when rotating, capture the seeds and fertilizer granules and send them into the seed pipes. Through corrugated seed pipes, the seed enters the cavity between the coulter discs, rolls along special guides and falls into the furrows formed by the coulters. Further, the furrow with the applied fertilizers and seeds is sealed with harvesters, and the relief is leveled with plumes.
SZ-3.6 seeder adjustment
The coulter discs should be able to rotate easily by hand. In the place where the discs touch, the gap should not exceed 1.5 mm, the optimal thickness is 0.5 mm sharper than the disc, and the sharpening chamfer is 6-7 mm wide.
Seeding rate. It is adjusted before leaving the equipped site in the field. The seeder is lifted with jacks so that it is in a horizontal position, without distortion. Lay a tarp or other material under it. After that, filling the container with seeds by about a third, fill the coil, spinning the wheel 2-3 times.
The next step is to make a mark on the wheel and turn it 14 times. The poured seeds are weighed, and the result is multiplied by 100, the resulting product is the actual seed rate for an area of 1 hectare.
SZ-3.6 seeder operation
To find out the advantages and disadvantages in the operation of the grain seeder SZ-3.6, we, as always, turn to farmers, people who are familiar with this unit in practice.
- I have been using my seeder for over ten years. The load on it in my farm is not large, only about 30 hectares. Collected parts from scrap metal, which by that time was already heavily used. For all the time of breakdowns, only a couple of bearings were replaced with openers. An excellent device for a small farm, for large areas, of course, I recommend something more serious and modern.
- Not a bad technique. If you are in trouble with finances, then you can't imagine better, especially since you can find a not bad used option, there are enough offers and prices do not bite. The device itself is decent, reliable, there is essentially nothing to break and it can be repaired on the knee in no time.
Based on the many reviews, people directly operating this technique, we can say with confidence that they say many times more positive things about SZ-3.6.
Among the main advantages, such qualities are noted: ease of maintenance, design reliability and maintainability, the possibility of self-adjustment without the involvement of specialists, the availability of components and their low price, as well as the price of the seeder itself.
They only say about the shortcomings that the model is outdated and inferior in performance and economy to more modern models.
Buying a second-hand SZ-3.6 seeder: selection features
The seeder itself is very reliable, and you need to try to ditch it. Therefore, when choosing this technique in the secondary market, you need to pay attention first of all to mechanical damage in the design of the seeder. They can be easily detected by anyone, even not versed in the topic, upon careful visual inspection.
We also pay attention to rotating and rubbing parts subject to wear, such as bearings and coulter discs.
Prices for an old used SZ-3.6 seeder in working order start at about 50 thousand rubles. Further, the price increases depending on the year and technical condition.
Currently, a huge number of a wide variety of agricultural equipment is produced, including trailed grain-sowing units. Among such equipment, it is worth highlighting such seeders as SZ-3.6 and SZ-3.6A, which were developed specifically for sowing cereals, legumes and other crops, and introducing granular fertilizers into the furrow, simultaneously with the seed. There are no problems with repair and spare parts for this equipment.
The advantage of this equipment is the feeding of granular mineral fertilizers into the soil to a depth of 80 mm simultaneously with the seed. The pneumatic wheels of the unit allow it to move rather quickly, and sensors that control the rotation of the shafts of the seeding devices and the depth of the openers will notify the operator in time about their incorrect functioning.
This unit enables the tractor driver to work independently, without involving the labor of a hitchhiker, which would be impossible when using a multi-seeder unit. When replacing one type of opener with another, and using additional equipment, the seeder can sow even on reduced row spacings, while simultaneously introducing seeds of a different crop.
Before starting to work with the unit, you should check its completeness, correct assembly, adjust the seeding devices and markers, the location of the openers, etc., if necessary, replace spare parts.
Checking equipment before work
First of all, it is necessary to check the containers for mineral fertilizers and seed material for integrity and the presence of foreign objects. It is also necessary to inspect the vas deferens to ensure that there are no foreign objects and possible lumps from germinated grains. Check that the coulter discs rotate freely and that the cutting edge of the discs is not more than 0.5 mm.
It is advisable to set up disc plowshares on a special installation site, where it is necessary to mark the middle of the seeder, having previously installed a marking board between the wheels and aligning the marked mark with the center of the unit. Further, the fastening of the coulter leashes is loosened, which must be combined with the risks on the board at intervals of 300 mm for the front and rear row.Field operation and configuration
The preparation of the field for the sowing includes determining the method of movement of the seeder, marking the turning points, dividing the area into corrals, beating off the test run line.
Sowing should be done across the direction of the arable land and last tillage, or at least at an angle. During test runs, adjust the seed rate if necessary. For this, seed is poured into the hoppers with a layer thickness of 5-8 cm, and this level is marked on the wall of the container. After the first trial runs, it checks how much seed has been consumed from the inspection lot. If necessary, the seed feed rate is adjusted using the regulator knob and the test pass is repeated.
The depth of the coulters is adjusted by means of a regulator located on the coulter. For maximum penetration, screw in the screw all the way.
A grain-fertilizer seeder, as well as any original spare parts, can be purchased at a fairly favorable price directly from the manufacturer or from official dealers of agricultural machinery.
Parameters
Seeder SZ-3.6A
The grain-fertilizer seeder SZ-3.6a is designed for sowing grain and leguminous crops with the supply of mineral fertilizers to the soil simultaneously with seed material. The seeder has a mechanism for overlapping some of the seeding devices to create tramlines when using the technology of intensive cultivation of agricultural crops. The machine is equipped with coulters and soil embedding devices, so the seeder can be easily converted from one version to another. If used equipment is used, then before work it is necessary to check all components and, if necessary, replace with spare parts strongly worn out parts.
The seed feed rate is set by adjusting the working length of the coil, adjusting the valves of the seeding mechanisms and changing the speed of rotation of their shaft. Adjustment of the fertilizer feed rate is carried out using the handle.Planter preparation
Before starting sowing, it is necessary, first of all, to check the completeness of the unit and the compliance of the working elements with the technical requirements. The unit is set up on a marking site. A marking board is placed between the wheels of the unit to adjust the openers to the required distance between the rows.
When adjusting fertilizer application mechanisms, first of all, adjust the position of the valves. To do this, the reset knobs are shifted to the upper extreme position, at which all the dampers will touch the coil rods. After that, the valves are rearranged with the release lever so that the gap between them and the bobbin rods is 8-10 mm.
Setting the seeding depth
This procedure is usually carried out in situ just prior to sowing. The smallest depth of the coulters is obtained when the depth adjuster is completely turned out, and the greatest - when the adjusting screw is turned all the way down. The same depth is achieved by adjusting the spring compression for each individual opener. To determine the seeding depth, the processed furrow is broken and the distance from the seeds to the upper edge of the row is determined. If the non-compliance with the norm is more than ± 10 mm, the sowing depth is corrected and a second check is performed.
You can buy the SZ-3.6A seeder and original spare parts for it directly from the manufacturer, as well as in agricultural machinery stores.Parameters
Equipment cost overview
As you can see, the price of new and used equipment may fluctuate depending on the region or technical condition (if it is a used unit). It is now easy to buy spare parts for seeders, since they are available in almost any agricultural equipment store.
The purchase and use of SZ-3.6 and SZ-3.6A units makes it possible to efficiently and efficiently carry out sowing work, and, therefore, significantly save time and money.
It is used when sowing seeds: wheat, rye, barley, oats and when sowing peas, beans, soybeans, lentils, lupine and other leguminous crops with the simultaneous introduction of granular mineral fertilizers into the rows.
The S3-3.6A seeder can be equipped with: double-disc openers (for seed drill), single-disc openers and harrowers
when feeding winter crops, with double-row openers and harrowers (for sowing flax seeds), double-disc double-row openers (for working on soils clogged with stones), double-disc single-row openers with thickened discs (when sowing on peat bogs).
The seeder in single-seeder units is aggregated with tractors: T-40; T-40A; T-50; T-50A; MTZ-50 / 52L; MTZ-80; MTZ-82 / 82L; YuMZ-6L / 6M; T-80A; T-10AV. In wide-cut multi-seeder units with the use of hydraulic couplers SP-11 A; SP-16A it is aggregated with DT-75 tractors; T-150K; T-4A and K-700.
A distinctive feature of the S3-3.6A seeder from the SZ-3.6 seeder is the following.
In the SZ-3.6 A seeder, individual finger-type harvesters are introduced, the following are used: a welded structure for fastening the axles of support-drive wheels, small-sized gearboxes (gearboxes); the design of the grain hopper has been changed (a rigid bottom is installed), the shaft for lifting and deepening the openers; supplied protective nets in grain and fertilizer boxes; used: a hook-on device with a central folding chute, a device for adjusting the seeder to the seeding rate without lifting the support wheels, openers-rippers on the track of the tractor wheels, a device for overlapping seeding devices to form a tramline; the USK electronic system of group control over the operation of the seeding devices and the level of seeds and fertilizers in the boxes was used.
The seeder includes: a frame, boxes for grain-fertilizers 3 (Fig. 1) and for tools 11, a frame with a trailer 1, a unified control system (USK), a gearbox, wheels 10, a footboard 4, harvesters 5 and 7, a stand 6, 8 openers, reflector.
Rice. 1. Diagram of the device of the S3-3.6A seeder:

Attached to the frame of the seeder are: a grain-fertilizer box 3, two pneumatic wheels 10, and the opener bar of the frame is equipped with openers 8. To the front of the frame is attached a frame 1 with a trailer and a stand 12. To the gussets of the frame, the opener lifting shafts are attached. Hydraulic cylinder 2, located on the control coulter, lifts and lowers the 8 openers and 7 harrowers.
With the help of a counter-drive shaft and two gearboxes (gearboxes), the shafts of grain and fertilizer machines are set in motion. The counter-drive shaft is equipped with an overtaking clutch, which allows these shafts to be driven from both wheels at the same time. A footrest 4 is mounted on the rear of the frame.
The seeder workflow is as follows. Received seeds in the grain-fertilizer compartment of box 3 and fertilizers in its fertilizer compartment are fed by gravity into the receiving chambers of the seeding devices. During the operation of the seeder, seeds and fertilizers are picked up by rotating coils of grain and fertilizer sowing devices, which bring them to the funnels of the seed pipes. The seed tubes feed the seed and fertilizer into the openers, from which, rolling in directions, they fall to the bottom of the furrows created in the soil by the openers. The filling of seeds and fertilizers with soil is carried out with the help of natural shedding of the soil from the walls of the furrows, and its compaction is carried out by the harvesters following the openers.
The grain box consists of two compartments: a front (seed) compartment and a rear compartment for fertilizers. On top of the grain box is equipped with sieves that protect the seed from the penetration of foreign objects into it. The grain box has four lids equipped with spring latches for fixing them in the open and closed positions.
The grain reel metering units are attached to the bottom of the box. The devices have group emptying and the same seeding rate adjustment. The grain metering unit is equipped with an adjustable valve that facilitates the sowing of small as well as large seeds. This valve is controlled by tightening or loosening the spring with a nut. Group adjustment of the valve position and emptying of the apparatus is carried out using a lever.
Reel pin devices for seeding granular mineral fertilizers with group emptying are attached to the rear wall of the box. Emptying is carried out by a lever that turns the shaft with the valves attached to it.
When sowing seeds without applying fertilizer, both compartments of the box are filled with seeds. In this case, the windows of the fertilizer dispensers are closed with latches and the shutters are pulled out.
Openers. The seeder can be equipped with: double-disc openers, single-disc openers, double-disc narrow-row openers.
A two-disc row opener with a 10 ° toe angle of discs includes a cast-iron body 4 (Fig. 2, a), two discs 1 with hubs 2 with pressed-in bearings protected from axial displacement by spring rings.
Hub 2 with a pressed-in collar and bushing retains the lubricant in the bearing cavity and prevents dust from entering it. The discs on the axles are secured with nuts. The coulter discs protect the scrapers from sticking the soil.
The double-disc row opener differs from the double-disc opener in thicker discs and a scraper design.
The narrow-row double disc opener has an 18 ° toe angle and can be installed on both the front and rear rows. Discs 1 are attached to the axles located in the coulter body (Fig. 2, b). The discs are connected to the hub 13 by rivets 12. The bearings 11 are pressed into the hub and fixed with a ring 10. The hub 13 is protected from the penetration of dust and dirt into the bearing by a collar 9 and a reflector mounted on the axle.
The front and rear single-disc openers have a flat disc shape and are mounted so that their plane of rotation with the direction of movement is 8 °, and with the vertical 20 °. The rear and front openers are positioned in pairs on the drill. The left openers are mounted on the left half of the drill and the right openers are mounted on the right half.
The coulter disc 1 (Fig. 2, c) is attached to the hub. Bearings 11 are pressed into the hub, which keep the rings 10 from axial displacement.
A distinctive feature of the assembled front opener from the assembled rear opener is the angle of inclination of the arm 14 to the horizontal. In the front opener, the mentioned angle is 31 °, and in the rear opener, 19 °, therefore the distance from the top of the funnel 16 to the outer end of the bracket 14 in the front opener is smaller, and in the rear opener it is larger.

Shaft coulter has a bracket 18 (Fig. 2, d) and arrow-shaped shaft 19. Install the coulter along the track of the wheel. Front and rear openers are not interchangeable. The unified control system of the seeder's working process includes seeding and seed level sensors, a distribution cable and a control panel. Seeding sensors record the movement of seeds dropped into the seed tube by the seeding wheel and send light and sound signals to the control panel about a process violation. An alarm is given when the level of seed or fertilizer in the box is below the location of the sensors. The sensor is based on the photoelectric principle.
Preparation for work.
Preparation for work begins with checking the technical condition of the working bodies and mechanisms of the seeder, placing the openers at a given width. The coulters are placed on a marking board. This board is placed between the rows of openers with the signs up and so that the middle of the board coincides with the longitudinal axis of the seeder. The board is strengthened with pegs. Place the openers against the corresponding signs marked on the board. You can preliminarily place and slightly fix the openers on the bar, and then, using a marking board, install them completely.
On the roll for adjusting the depth of the rolls are positioned so that the push rods are placed vertically to the axial line of the openers, after which the nuts for fastening the drivers to the bar are tightened to failure.
In the absence of a setting board, the openers are placed at the required row spacing using a tape measure. To do this, the extreme openers are moved along the bar to failure and the distance between their center lines is measured. This distance is the usable coulter bar length. Divide this length by the required row spacing and add one to the result to get the number of openers that can be mounted on the bar.
Adjustment of grain sowing devices begins with checking the face of the coils of grain devices with the inner cavity of the sockets. In the presence of devices, the coils of which do not face the cavity of the sockets, release the locking screws securing the coils to the shaft and install the coils so that the ends of the coils face the inner cavity of the socket.
Check the installation of the valves of the seeding devices. For sowing grain crops, the gap between the valve planes and the lower ribs of the couplings in all devices should not exceed 2 mm. The valves are adjusted by tightening or loosening the spring at the required valve with a bolt.
When sowing seeds of leguminous crops, set the gap between the plane of the valve and the edge of the coupling, equal to 8-10 mm. This gap will prevent the seeds from crushing. Set the clearance with the emptying levers.
Check the installation of the gearbox (gearbox).
The gearbox, together with replaceable sprockets, allows you to get sixteen gear ratios, including ten for the grain shafts and six gears for the shafts of the fertilizer apparatus. The gearboxes differ from one another only in the arrangement of the ends of the input shafts.
The gear ratio is chosen so that the seeding rate corresponds to its minimum value, but with the maximum length of the working part of the coils. This will allow you to get the most uniform sowing of seeds and eliminate their crushing in the apparatus. The length of the working part of the coils is determined depending on the adopted gear ratio, having previously determined it from the diagram.
Example. It is necessary to determine the value of the opening of the coils and the gear ratio at a wheat seeding rate of 80 kg / ha.
On the vertical axis, find the rate of 80 kg / ha and draw a horizontal line that crosses the inclined "wheat" lines. Having found the intersection points, we will see that this norm corresponds to the gear ratios of 0.604 and 0.198. From the points of intersection, lowering the perpendiculars on the horizontal axis, we obtain the length of the working part of the coils, equal to 10 and 31 mm.
Considering that the seeds of one crop, for example wheat, have different characteristics, the given diagram is used to guide the setting of the seeding rate.
To clarify the seeding rate, carry out a test test seeding on site. The seeder is lifted with jacks so that the supporting-drive wheels, rotating, do not touch the ground, and the grain-fertilizer box takes a horizontal position. The seed compartment of the box is half filled with grain, and the regulator lever of one half of the seeder is set to a scale division approximately equal to the seeding rate. The seed tubes are equipped with sacs.
It is accepted to check the seeding rate on an area of 1/50 hectares. Therefore, the wheel of this seeder is turned 14 times in the direction of the seeder with a frequency of 15-20 minutes.
The number of seeds sown by the devices (in kg) for one wheel rotation is calculated according to the formula A = 3.14BDQ / 10000, where B is the width of the seeder, m; D - wheel diameter, mm; Q - seeding rate, kg / ha.
The number of seeds sown by each half of the seeder (kg) for 14 rotations of the wheel will be: A = 3.14 x 14DBQ / 100002.
The seeds sown by the seeder are collected, weighed and the result is compared with the calculated one. If they differ, the length of the working part of the coils is changed with a lever and the scrolling is repeated again. The check is finished when the actual deviation of the seed sowing by the seeder is within 3% of the specified rate. Having received this result, the regulator lever is secured with a nut.
After checking the seeding of seeds with one half of the seeder, make a template for the working length of the spool. This template is used in the field when checking the seed rate. It is checked in the field during the first passes of the machine.
The number of seeds, kg, which should be sown, is calculated by the formula: A2 = LBQ / 10000, where L is the length of the rut, m.
At 1/3 of the bottom, fill the seed compartment of the box with seeds, align them and draw a line along the walls. Then the box is filled with seeds, the amount of which is calculated according to the above formula. Then they drive two rutting lines and, after completing them, determine the correct setting of the seeder to the seeding rate, while being guided by the drawn control line. If the actual seeding differs from the calculated one, the seeding devices adjust and check again.
The adjustment of the fertilizer apparatus begins with checking the touch of the fertilizer apparatus. For this, the lever is moved to the uppermost position. In this case, the valves of all fertilizer devices should be in contact with the pins of the coils, loosen the locking bolts and put the valves so that they are in contact with the coils. Then, by turning the lever, the gap between the pins and the valves is set to 8-10 mm for fertilizers with normal moisture content, and for fertilizers with high moisture content, the valves are lowered lower.
Fertilizers of even one type differ in moisture content, volumetric weight, etc. Taking this into account, the setting of the preset seeding rate of fertilizers is carried out during a trial seeding. It is produced similarly to that described when checking grain machines.
The SZP-3,6A trailed grain-fertilizer seeder is used for row sowing of seeds of grain, small- and medium-seeded legumes with the simultaneous introduction of granular mineral fertilizers into the soil and rolling the soil after sowing.
The seeder in single-seeder units is aggregated with tractors: T-40; T-40A; T-50; T-50A; MTZ-50 / 52L; MTZ-80; MTZ-82 / 82L; YuMZ-6L / 6M; T-80A; T-100 AV. In wide-cut multi-seeder units with hydraulic couplers SP-PA; SP-16A it is aggregated with DT-75 tractors; T-150; T-4A and K-700.
A distinctive feature of the SZP-3.6A seeder from the SZP-3.6 seeder is the following. In the SZP-3.6A seeder, individual finger-type harvesters are introduced; applied: welded construction of axles of support-drive wheels, small-sized gearboxes; the design of the grain hopper has been changed (a rigid bottom is installed), the shaft for lifting and deepening the openers; supplied protective nets in grain and fertilizer boxes; used: a trailing device with a central folding chute, a device for adjusting the seeder to the seeding rate without lifting the support wheels, openers and rippers on the track of the tractor wheels, a device for overlapping seeding devices to form a tramline; the USK electronic system of group control over the operation of the seeding devices and the level of seeds and fertilizers in the boxes was used.
