The disadvantages of this plow include increased tractive resistance due to the introduction of additional working bodies, the uneven distribution of fertilizer around the arable horizon.

This design plough adopted us in to the number of the nearest equivalent.

The invention consists in the following. The problem to which the invention is directed, is to simplify the design, a uniform distribution of fertilizer around the arable horizon.

The technical result - the reduction of traction resistance, increased yields. This technical result is achieved by the fact that in the famous plough-dobrile, including fixed on the frame of the conveyor section and fertilizer distributors with tokoprovodom, according to the invention, a fertilizer distributing apparatus provided with an air system for a pressurized supply of fertilizers containing high-pressure fan with drive motor and duct having branches to each fertilizer distributing apparatus, and calopresti installed in racks dumping cases and hermetically connected with slits made between the blade and blade enclosures and directed along the tangent to the ploughshare, and the pairing of tokoprovodom with slits made on the arc of a circle, a fertilizing apparatus includes a hermetically sealed cylindrical jar, the bottom of which is placed a disk dispenser, representing a vaned rotor, the blades of which are made on a logarithmic spiral, the cylindrical cover banks made the pipe for connection with the exhaust duct, the nozzle is connected by a channel in cylindri eskay Bank with the sowing window, made in the bottom of the banks, the front wall of the channel has a height limiter layer of fertilizer on the drive shaft, a fertilizer distributing apparatus provided for the agitator drive fertilizing machines made from the PTO of the tractor, drive-removable dispenser, the thickness "δ" which is selected depending on the fertilizer.

Final section of the plow consists of a blade 7, plowshares 8. To the rear of the blade 7 and the plowshares 8 fixed calopresti 9. Between the blade 8 and the blade 7 is made tangent to the blade 8 slot 10 for the supply of fertilizer. TakeProfit 9 is conjugate to the slit 10 in the arc of a circle. Final section is fixed to the frame 1 plough through the uprights 11. Drive fertilizer distributing apparatus 6 production which is from the output shaft through the drive transmission 12. A fertilizing device 6 consists of a cylindrical banks 13, a bottom 14 which has a disk-hopper 15, which is fixed on the drive shaft 16, the plate 14 is hermetically fixed TakeProfit 17. Cover fertilizer distributing apparatus has an air tight seal 18 and the pipe 19. To the drive shaft 16 is fixed to the agitator 20. Drive-hopper 15 has a blade 21, made on a logarithmic spiral, cylindrical Bank limited 13 of the front wall 22 which separates the space from banks sowing window 23. The front wall 22 has a height limiter layer of fertilizer on disk-dispenser 15. The rear wall 24 of the channel separates the space from banks sowing window 23.

Plow-utopical works as follows.

Before working on the bottom 14 of the cylindrical banks 13 is set disc dispenser 15, calculated at a given rate of fertilizer application.

When the movement of the plow fertilizer captured by the blades 21 of the disk dispenser 15 and serves to seed the window 23.

However, they are captured by the air flow high-pressure fan 3 through the channel formed by the front wall 22 and rear 24, and fed through a metering window 23 in TakeProfit 17. From toolprovider 17 fertilizer with air directed to calopresti 9, fixed to the rear side of the blade 7.

Calopresti 9 direct fertilizer the air flow in the gap 10, made between the blade 8 and the blade 7.

Since the slit 10 is directed along the tangent to the blade 8, the flow of fertilizer from the air will flow under a layer of soil, the cutting blade 8.

When the movement of the reservoir on the blade 7, the layer is bent and loosened. In the loosened soil lumps are formed, between which flows a stream of air with fertilizers, which saturate the entire arable horizon. In addition, the resulting air gap between the soil layer and the blade reduces the tractive resistance of the plough. Rich fertilizers arable horizon soil provides plants with the available nutrients and the productivity is increased.
