The invention relates to agriculture and forestry, and is intended for tillage and sowing.

It is known tool for tillage and seeding (SU 1158063 A MKI And 01 B 49/06, bull. No. 20, 30.05.85), comprising a frame, a disk working bodies, separating the lattice in the form of bars, cantilever mounted on the rear part of the plow blade, rotary working body with knives, vomer, the seal bars of the grating attached to the plow rigidly and arranged in intersecting planes.

The disadvantage of this device is that of mixing wet and dry soil, weed seeds fall into the same horizon, and that the seeds of cultivated plants, the opener is embedded in a soil layer, yet fragmented, which creates increased energy consumption.

Famous meadow unit (Avts No. 176126, MCI And 01 B 49/06, published 26.10.1965, bull. No. 21), comprising a frame, a soil cutter, fats and seratraline drills, cylindrical ice rink and transport wheels. The VAS deferens zernotravyanogo the drill is inserted the lower end of the tube, is mounted behind the cutter, the lower edges of which are beveled away from the cutter and located perpendicular to the flow of soil cast cutter. The tubes of the VAS deferens are mounted on an adjustable height bar. The unit is equipped with a hinged frame with four screw mechanism open t the PA. Cylindrical rink is equipped with auger cleaner with the right and left wound coils.

The disadvantage of this device is its greatest intensity, as the cutter creates a traveling wave that dissipates energy in space. Soil layers are mixed and weeds so they are all horizons. The tubular form of the openers has poor flow, and therefore the soil, cut by a cutter, not evenly distributed across the width. In addition, the device for regulating the depth of cultivation and seeding is difficult for the device.

The invention solves the problem of reducing energy consumption, conserving natural addition of soil layers, improving the quality of the seed.

The technical result is to increase productivity, reduce fuel costs, improve the quality of the seed.

This technical result is that the planting unit comprising a frame support-drive wheels, a rotary grinder, a drill with the VAS deferens, the inserted lower ends to the openers, located perpendicular to the flow of soil cast rotary shredder according to the invention for openers, made with a threaded adjustment holes, the pinned section for Tusk with a cheek, in front of the rotary shredder which has a capability is aromasine in a vertical plane, is a plow attached to the sidewalls and the center of mass of the working elements of the rotary shredder is shifted to the end.

1 shows a General view of the seed unit in longitudinal section, figure 2 is a longitudinal and a transverse incision Coulter.

Planting unit consists of a frame 1 to which are secured the brackets 2 to attach the rods of the support frame of the tractor. Frame 1 rests on the drive wheels 3. Also to the frame 1 is attached bevel gear 4 connected to the PTO shaft through the drive shaft 5. Bevel gear 4 is connected chain transmission with rotary 3 shredder 6, is arranged to move in a vertical plane. The rotary shredder 6 assigned a work item 7. The center of mass of each work element 7 is displaced to its end. To the frame 1 is attached to the hopper of the planter 8. Metering unit 9 with the VAS deferens 10 fixed to the hopper 8. In addition, to the frame 1 are fixed, the applicators 11, sidewalls 12 and blade 13. For openers 11 fixed nachalnika 14, with cheeks 15. On the opener 11 is made of an adjusting screw holes 16. The section for Tusk 14 is fixed in the adjusting screw holes 16 by screws 17. The applicators 11 are perpendicular to the flow of soil cast rotor shredder 6.

When the movement of seed unit rotates the drive shaft 5 and the pinion bevel gear 4 Chain transmission transmits rotation from gear 4 to the rotary shredder 6. Simultaneously with the movement of the blade 13 and the sidewall 12 cut soil layer, which acts on the surface of the plow blade 13. Thus, in a longitudinal vertical plane layer is separated from the array of sidewalls 12 and horizontal plowshare 13, that is, the layer at the gathering with a plow blade localized. Rotary shredder 6 working bodies 7 generates a pulse mechanical effect (impact) on top of the localized layer at the gathering it with a plow blade 13, acting on the upper surface of the soil bed with a frequency matching with multiple natural frequency of the soil layer.

That is, it creates a resonance standing waves - waves of compression-tension. They, acting, destroy the formation. Layer peeled off in layers on the Shoe 11 and the section for Tusk 14 without disturbing the addition of its layers. In addition, the reservoir being at the gathering with a plow blade 13, crushed the working bodies 7 and partially thrown back in powdered form, getting their particles on the Shoe 11 and the section for Tusk 14. The Shoe 11 and the section for Tusk 14 affect the soil with minimum effort. Basic mechanical stress on the soil has the cheek 15 section for Tusk 14, raking the soil to the side. When the fastening section for Tusk 14 on the lower threaded hole 16 of the Shoe 11 will be the minimum depth of seeding on the upper threaded hole maximum depth of seeding. Results the metering unit 9 is carried out of the drive wheel 3. Metering unit 9 moves the seed from the hopper 8 into the VAS deferens 10, and the seeds fall to the bottom of the furrow done by Coulter 11.

Depending on the depth of tillage is regulated by the position of the rotary shredder 6 relative to the upper surface of the layer.

When tillage cutter FLN-0.8 in the unit with the tractor DT-75S fuel consumption was 36 kg/ha of fuel Costs for planting 1 ha drill SF-4 in the unit with the tractor T-16M was 6.94 kg Total costs for planting and processing of one ha was 42.94 kg of diesel fuel. The cost of fuel, we offer a sowing unit with the tractor DT-75S was one ha 34.352 kg

Thus, the proposed planting unit has less energy than known units. In addition, the planting unit reduces the number of passes per unit area.

Planting unit comprising a frame, supporting and drive wheels, a rotary grinder, a drill with the VAS deferens, the inserted lower ends to the openers, located perpendicular to the flow of soil cast rotor shredder, characterized in that the openers made with threaded adjustment holes, fixed nachalnika with cheeks, ahead of a rotary grinder, made with the possibility of moving in the vertical plane, is a plow mounted on the oculina, and the center of mass of the working elements of the rotary shredder is shifted to the end.
