Description

Seeding device	dampers	Universal coil
Grain and fertilizer sowing devices are made of polymeric materials - this eliminates the possibility of corrosion and increases the service life.	The dampers on the fertilizer, grain and small seed machines have 3 positions each to regulate the supply of seed to the seeding wheels.	The grain sowing unit has a screw coil for sowing grain and leguminous crops and a pin coil for sowing small-seeded crops, as well as sowing loose and medium-loose grass seeds.
Variators	Double disc coulters
Variators provide easy and quick adjustment in the range of seeding rates: - for seeds from 0.7 to 400 kg/ha; - fertilizers from 25 to 200 kg/ha.	Offset disc coulter allows seeding with crop residues.	Planters can be equipped with single-row or double-row double disc coulters. The service life of coulters is increased by 100% due to the use of modern technologies for processing steels containing boron.
Press wheels	Zagortachi	Control system
The unified design of the unit "coulter-packer roller" allows you to adjust the coulter to a given depth with an interval of 1 cm.	Finger harrows replace rollers when soil moisture is high. The choice of closing devices allows sowing at different soil moisture.	The HELIOS electronic control system manufactured by MONADA SPC, installed on the seeder, controls the passage of seeds in one coulter on each hopper and transmits information to a monitor installed in the tractor cab, which allows you to keep track of the sown area. On a separate order, it is possible to install seeding control sensors on each sowing unit.

Powder coating

The line of powder coating Ideal-line (Denmark) is installed at the production site. This painting technology allows to produce high-quality paintwork with a warranty period of up to 8 years.

frame design

New lightweight frame design. The use of high-strength pipes of European steels makes it possible to reduce the weight of the frame structure while increasing its strength and rigidity, which leads to a decrease in tractor fuel consumption. The use of hardware with a strength class of at least 8.8 ensures reliability and durability of operation.

To improve the consumer properties of grain seeders of the ASTRA family, the following design changes were made to the design of the seeders:

• the design of the handle for adjusting the depth of seeding has been changed. This change prevents dust from clogging the inside of the handle and, as a result, prevents it from jamming when repositioned.
• the design of the mechanism for fixing the depth of seed placement has been strengthened. This change has increased the wear resistance of the depth adjustment knob, and as a result, increases the life of the assembly.

The design of grain sowing machines has been changed, which improved the passage of seeds in the necks of the machines, and as a result, increased the seeding rate of poorly flowing seeds of grain crops, such as oats and barley.

ASTRA seeders have a hopper with the possibility of separate filling of seeds and fertilizers, which eliminates the mixing of seeds in the hopper.

The seeder allows you to sow up to 3 hectares with one load at a seeding rate of wheat of 200 kg/ha and seeding of mineral fertilizers of 100 kg/ha.

Using the SP-8 hitch, you can create wide-cut sowing units from two seeders. Seeders in the unit are interconnected according to the rank scheme. This connection facilitates the loading of seed.

Specifications

Seeder SZP 3.6 is an agricultural machine designed for planting grain crops (rye, oats, wheat, barley) and legumes (beans, peas, lentils) in rows with a distance of up to 15 cm, as well as for fertilizing and rolling the sown rows.
The degree of unification of components and parts within the SZP 3.6 family of seeders reaches 77-98%, which simplifies the manufacture, operation and supply of spare parts.
The seeder can work both in a single-seeder and in a multi-seeder row unit (3-4 seeders each). In single-seeder units, the SZP 3.6 seeder is aggregated with tractors of traction class 0.9-1.4, and in multi-seeder units - with tractors of traction class 3.0-5.0, more powerful than the tractor.

A voluminous hopper for seeds and fertilizers, pneumatic support wheels, rolling bearings, hydraulic lifting and lowering of working bodies, the ability to use hitches to assemble multi-seeder units with power-saturated tractors provide high quality sowing with simultaneous fertilization, high productivity, simplicity and convenience in operation, reliability no worse than seeders.

Device of a seeder SZP 3.6

The basis of the unit is a metal frame. It rests in front on two pneumatically driven wheels. On top of the frame are all control and adjustment mechanisms, as well as a hopper for fertilizer granules and seeds.
The openers are raised and lowered hydraulically (an external hydraulic cylinder is fixed to the frame base). Ring type rollers are hinged to the frame. A three-speed gear reducer connected to the wheels of the machine is switched by a lever. Torque is transmitted from it to the shafts of the sowing mechanisms - a chain drive is used for this. An uncoupler is used to stop seeding when openers are up.
An overrunning clutch is used to transfer rotational energy from both wheels or from two rollers located at the edges. When the machine is operating, the coulters make trenches, where they fill up with the necessary interval of grain and fertilizer coming from the hopper through the funnels into the coulter sockets. The edges of the trenches then crumble naturally, covering the seed. The following rollers "tread down" the surface of the soil, and it is leveled with a special trail-harrow. As structural materials, the same ones are used.

1 - seed ducts; 2 - frame; 3 - mechanism for raising and lowering openers; 4 - grain fertilizer box; 5 - suspension; 6 - front end with a trailer; 7 - reducer; 8 - footboard; 9 - rollers; 10 - coulters. To use the unit, you need a tractor to which it attaches. As already mentioned, with the help of hitches of the SP type, you can create a multi-seeder design. Just keep in mind that only a sufficiently powerful tractor (with a traction force equal to 3 or more) can move it.

Video review of the SZP 3.6 seeder

To provide agricultural plants with the necessary amount of nutrients, light and moisture, their seeds must be evenly distributed over the entire area at a certain depth.

Depending on the chosen method of sowing, there are seeders: ordinary (for sowing various crops in continuous narrow-row, cross, wide-row and belt methods); dotted (for row sowing with the placement of seeds in a row at the same distance from one another); square-nested (when seeds are placed in nests at the corners of a square or rectangle); nesting (for placing seed nests in parallel rows). Seeders that sow mineral fertilizers simultaneously with sowing seeds are called combined.

By appointment, seeders are divided into universal and special.

Universal are designed for sowing seeds of various crops (cereals, legumes and oilseeds, as well as herbs, etc.). Special seeders are used for sowing seeds of one or two or three crops (beets, cotton, corn, vegetables). Universal seeders, as a rule, are produced trailed, which makes it possible to make a sowing unit from 1 ... 6 seeders, and special - mounted.

Grain fertilizer press seeder SZP-3,6

It is designed for row sowing of cereals, legumes and other crops with the introduction of granular mineral fertilizers in arid areas and on soils subject to wind erosion. This seeder is a modification of the basic model and differs in that it is equipped with self-aligning pneumatic wheels at the front and rollers at the rear that roll the soil after sowing. With increased soil moisture, it is possible to install pneumatic support-drive wheels instead of rollers.

Scheme of the device of the SZP-3.6 seeder

We give a complete diagram of a grain fertilizer seeder and give an explanation of it

a - device; b - diagram of the gear mechanism; 1 - coulters; 2 - frame; 3 - self-aligning wheel; 4 - front; 5 - opener lifting mechanism; 6 - seed ducts; 7 - grain fertilizer box; 8 - gear mechanism; 9 - foot board; 10 - roller; O1, O2 and O3 - gear installation centers; A, B, C, G - drive gears of fertilizer seeders; D, E, F, I - drive gears of grain sowing machines.

The trailer design allows all planters to be connected directly to the hitch bar. Adjacent seeders are connected by a hinged link.

The SZP-3.6 seeder consists of a frame 2 (a), to which a front end 4 is attached with a trailer and self-aligning wheels 3, a coulter lifting mechanism 5, two grain-fertilizer boxes 7, coulters 1, grain and fertilizer sowing machines, which are driven by rolling rollers 10 through the gear mechanism 8.

If sowing is carried out without rolling, then the sowing units operate from support-drive wheels installed instead of rolling rollers.

Features of SZP-3.6 adjustments. Trailer brackets are installed on tractors and the air pressure in the tires of the front wheels is adjusted to 0.1 MPa, and the rear wheels to 0.08 MPa. On the hitch bar, the places for attaching seeders and extensions are marked, starting from its middle, symmetrically to the center line of the tractor. Markers are installed on the sowing units, the departure of which is indicated in the table.

The outreach of the markers corresponds to driving along the track of the marker with the outer edge of the right caterpillar, and for wheeled ones, with the middle of the right wheel.
Depending on the seeding rate, the gear ratio and the length of the working part of the coils are selected according to the nomogram.

Nomogram of the approximate dependence of the seeding rate on the length of the working part of the coil and the gear ratio of the drive.

At the same time, they strive to obtain a given seeding rate at the lowest gear ratio and a larger opening of the sowing machine coils. The required gear ratio is obtained by rearranging the gears D, E, G, I (b) and the table below.

With the help of a nomogram, a preliminary seeding rate is set. Therefore, before leaving for the field, they clarify the setting for the seeding rate of seeds and fertilizers and bring them into line with agrotechnical requirements. The seeding rate of fertilizers is regulated by rearranging gears A, B, C and D (b) and the table below.

The correctness of the installation of the seeder for the seeding rate is finally checked in the field. To do this, determine the number of seeds necessary for the seeder to operate at the control length of the rut at a given seeding rate, according to the formula:

G 3 \u003d 2 (LB p H c) / 10 4,

where C, - the number of seeds that the seeder sows on the control plot, kg; L - rut length, m; Вр - working width of the seeder, m; Нс - seeding rate, kg/ha.
The grain box is filled with seeds to % of the volume and the level is marked with chalk.

Then, the amount of grain found according to the formula is poured in and sowing begins at the control length of the rut. After the passage of the machine-tractor unit of one circle, the position of the level of seeds in the grain box is determined.

If the level matches the mark, the setting is correct. If the level of seeds is above the mark, the rate is underestimated, if it is lower, it is overestimated.

The design of the seeder allows you to apply granular mineral fertilizers simultaneously with the sowing of grain crops, pack the soil in the sown rows, maintain the same rate in sowing on curved sections, transfer the coulters from the working position to the transport position using the tractor hydraulics, replace the rear drive wheels with four sections of the press rollers (for press option) on soils subject to wind erosion. Thanks to the use of bearings in the coulters, maintenance time has been reduced, as the number of lubrication points has been reduced.

The degree of unification of components and parts within the family of seeders SZ - reaches 77-98%, which simplifies the manufacture, operation and supply of spare parts.

The seeder can work both in a single-seeder and in a multi-seeder row unit (3-4 seeders each). In single-seeder units, the SZP-3.6A seeder is aggregated with tractors of traction class 0.9-1.4, and in multi-seeder units - with tractors of traction class 3.0-5.0.

A voluminous hopper for seeds and fertilizers, pneumatic support wheels, rolling bearings, hydraulic lifting and lowering of working bodies, the ability to use hitches to assemble multi-seeder units with power-saturated tractors provide high quality sowing with simultaneous fertilization, high productivity, simplicity and convenience in operation, reliability .

Seeder SZP - the most popular seeder in the world

Planter Champion

It is difficult to find an agronomist who is not familiar with the "szshka" - the SZ seeder. The first seeder of this model was created almost half a century ago. During this time, it has become a classic grain ordinary trailed machine. In the USSR, they were produced at the Kirovograd plant of agricultural machines "Red Star" (the modern name "Elvorti") in Ukraine, in Russia, "szshki" were made by the factories "Belinskselmash" in the Penza region and "Sibselmash" in Novosibirsk, they were also made in Kazakhstan.

The model turned out to be so successful that on the basis of the SZ-3.6 seeder, many modifications were developed: coulters for light soils, narrow-row ones for ordinary and stony soils, grain-grass, single-disk, roller for peat soils, flax, etc.

The high level of unification of components and parts within the family of seeders greatly simplified the manufacture, operation and supply of spare parts, combined with simplicity in design, maintenance and overall reliability in operation - all this contributed to the wide distribution of sowing machines.

In the vast territory of the former Soviet Union, there is probably not a single farm where these seeders are used. At the turn of the century, more than one and a half million such seeders had already been produced. Not a single seeder in the world was produced in such huge quantities.

From "szshka" to "szshushka"

For work on soils subject to wind erosion, a grain-fertilizer press seeder, SZP-3.6, was developed. In such a seeder, sowing takes place with the simultaneous rolling of each sown row. In addition to protecting the soil, the packer rollers not only protect the soil from erosion, but also ensure uniform sowing and uniform seedlings.

In 2016, the Rubtsovsk Spare Parts Plant began producing SZP seeders, in addition to the already wide range of plows and harrows. The VITA seeder "shot" - adapted to our conditions, it sows where six times more expensive imported ones are not able to work at all, not to mention their domestic clones.

What's new?

Of course, it was no longer the same seeder that left the Kirovograd workshops 50 years ago - domestic and foreign agricultural engineering has stepped far ahead. The design of components and assemblies and SZP seeders has changed and improved.

In the VITA seeder, the width of the working grip remained traditional - 3.6 m. The volume of grain fertilizer hoppers increased by almost 1.5 times, which made it possible to load large volumes of seed, reduce the number of stops for refueling and increase productivity.

The seeder uses a familiar and reliable gearbox, more precisely, two open (three-stage) gear gearboxes located behind the seed boxes. Together with chain drives, they make up the drive mechanism for seed and fertilizer sowing machines.

A modernized double-disk opener is used, the disks of which are offset by 6 mm relative to each other, which reduces traction, increases the resource of the opener and avoids clogging. As a rule, disc coulters work well in all soils. Due to the rotation of the discs, they almost do not clog or stick, allow sowing at high speeds, and have the ability to individually copy field irregularities.

Reinforced "problem" units: beam, drawbar, footboard. The position of the drive gear has been changed. In the original “szpshke”, the rink hit the drive at the slightest bump. With the VITA seed drill, this problem is solved - the roller is moved back by 7 centimeters, and does not come into contact with the drive.

To take into account these moments, direct feedback from the consumers themselves was needed. Before being put into production, the seeder not only passed mandatory tests at the Altai MIS, but also worked for a season on the farms of the Altai Territory. Comments and suggestions were taken into account and worked out.

New Perspectives

According to the Rosagromash Association for 2016, the Almaz association is in first place among Russian manufacturers in shipments of reversible plows, chisel plows and disc harrows, in second place in Russia in shipment of moldboard plows and in third place in shipment of mechanical seeders. .

Soil cultivation, plows and harrows are traditional for Almaz, and the high results here are not surprising. But the third place in the shipment of seeders is a great success, because their production was launched only in the previous year, 2015.

Tractor TDT-75: description and specifications

The TDT-75 tractor is a tracked vehicle of the third traction class. Produced by OJSC "Altai Tractor", served as the basis for the creation of modern skidding mechanisms TT-4 and TT-4M.

The machine has sufficient power to transport large- and medium-sized timber from cutting sites to storage areas in the absence of equipped roads.

It is used for loading and unloading of packaged timber. The chassis allows joint use with trailed and mounted equipment for various purposes.

TDT-75 effectively performs:

• logging processing of trunks, whip fragments;
• moving the trunks with the top back and forth;
• dragging cargo, with partial and full loading or suspension.

Unit Features

1. Low specific pressure on the soil. Wide tracks provide movement on uneven forest roads, snowy areas, swampy terrain.
2. The diesel engine, in its time, is quite economical in terms of fuel and lubricants consumption.
3. The chassis of the machine is universal - special devices are mounted on the platform, used in logging and primary processing of wood in off-road conditions.
4. Ground clearance provides sufficient cross-country ability.
5. Increased traction power transmission, high reliability of the undercarriage.
6. Metal protection mounted on the bottom of the frame.
7. The motor installed in the cab does not provide comfortable conditions for the driver.
