The invention relates to agricultural machines, and is intended for tillage.

Known tillage machine containing protective sleeve and cumulative capacity, made in the form of lattice bucket with attached bits, with cumulative capacity has lattice edges and bottom and secured by means of hinge with a protective casing. (GB A, CL AV 33/02, published. 15.04.1953). When working is known machines of the bit loosen the surface soil layer and move the loosened mass in cumulative capacity. However, the known device does not provide an effective loosening hard soil particles and does not provide deep loosening of the soil in General. Low efficiency of loosening and failure of crushing mineral soil inclusions significantly hampers the subsequent technological operations of sowing and planting of cultivated plants.

Known double-tillage cutter, containing the sample, different types of rotors, a Central bevel gearbox and final drive (see Patent RU, IPC, AV 33/00, publ. 27.05.2011 year).

The use of two rotors with the ability to change the angle of the mortar between them improves the possibility of grinding the solid soil inclusions, but does not provide the melting of the solid lumps m the General origin, especially in cases of remediation and restoration of the surface layer land. Rocky inclusion of natural origin, as a rule, the hardness of the destruction is much higher than can be generated force from one or more soil rotors. Because their use is ineffective for removing solid lumps from the surface of the cultivated field area. Attempts loosening hard lumps of earth with the help of one or more rotors only lead to rapid zatupleniju knives and is accompanied by low resource maintenance-free equipment operation.

The aim of the present invention is tilling the soil and its solid lumps, and the final elimination of them from the surface of the field. This goal is achieved by the fact that the proposed mill includes protective cover and storage capacity, made in the form of lattice bucket with attached bits, with cumulative capacity has lattice edges and bottom and secured by means of hinge with a protective casing. In addition, we offer the cutter includes a hinge and a rotor, which is driven from the PTO of the tractor through a Central conical and side gears, and on the bottom of the storage tank has a support beam attached to it by means of a rack packer roller, while the and the axis of the rink there are ledges, and racks are hollow inside which set the tappets with springs that allow shaking of the storage tank together with inside the soil mass. In the bottom of the storage tank has a discharge passageway, providing the opportunity periodic unloading of solid soil inclusions and stones from the cumulative capacity at the end of the rut movement of the unit.

In Fig. 1 and Fig. 2 shows the proposed mill is a side view and a view in plan respectively. In Fig. 3 and Fig. 4 shows a schematic diagram of work. In Fig. 5 and Fig. 6 shows the (increased) front axle and the roller in longitudinal section and cumulative capacity. Thus, the cutter has a portion 1, a rotor 2, a Central bevel gear 3 and the side gear 4, the protective cover 5, the cumulative capacity of 6, bit 7, a lattice-face 8 and the bottom 9 of the vessel. There is a hinge support beams 10 and 11 placed in the storage capacitor 6, and 12 hours, also packer 13. On the axis 14 of the packer rink 13 has projections 15. The pushers 16 spring 17 is placed within the racks 12. additionally, there is an unloading hatch 18 installed in the storage tank 6.

A tillage cutter is as follows: tractor unit before working on the field through a sample 1 translates the rotor 2 in the working Polo is a group of that is down on the surface of the earth. The movement of the rotor 2 (rotation) is supplied from the PTO of the tractor through the bevel gear 3, then the on-Board unit 4. The rotor 2 rotates in the earth, loosens her. Loosened and partially fragmented soil mass is discarded inertial forces of the rotor 2, limited in its movement by the protective cover 5. The lumps of earth, colliding on the protective cover 5, continue to deteriorate. Next earthen mass enters the holding tank 6, is made in the form of a lattice bucket and at the same time fulfilling the role of SITA. Small lumps of soil and aggregate together immediately sieved through a lattice-face 8 and the bottom 9 of the storage tank and placed on the surface of the field area. When this bit 7 perform the initial selection and movement of the soil mass and send it to the holding tank 6. Bit 7 installed with gaps between them and secured to the edge of the tank and thus provides a primary screening loosened soil mass. Accumulating tank 6 has a lattice faces 8 and plate 9, through which is provided free spillage of soil mass. To increase the intensity of sifting soil through cumulative capacity last 6 periodically shaken. To perform this nakopitel the Naya tank 6 connected to the protective casing is movable by means of the hinge 10, and then may oscillate relative to the casing 5. To ensure this, on the bottom 9 of the storage tank 6 set the reference beam 11, which with the help of racks 12 based packer 13. During the rotation of the packer rink 13 axis 14 occur oscillatory movement of the storage tank 6, which is transmitted via the pushers 16 from the protrusions 15 on the axis 14. Thus, solid lumps don't Wake up on the field surface and accumulate on the bottom 9 of the storage tank 6, whereas the loosened soil is placed evenly on the field and roll the roller 13. Further turning lanes or in a special place is the periodic discharge of solid lumps of mineral origin, as a rule, it is often required for treatments to restore or rekultiviruemye land - there are many lumps of mineral origin and residues of the breed. Uploaded lumps from the storage tank 6 by means of specially provided for in Luke 18. therefore, this tillage cutter provides fully loosening the soil and removing from the surface of the solid lumps.

After deep tillage of soil with a soil-cultivating tool with passive actuators in 2-5 years rotor-milling treatment is carried out for internal soil layers in the discrete zone of soil continuum in the layer of 25-50 cm. The width of the treated space of the soil continuum, for instance, 15 cm, 23 cm, 34 cm, is selected so that it makes not more than 1/3 of the distance between lines of deep tillage. The discrete zone of rotor-milling treatment of internal soil layers is placed in the soil continuum symmetrically so that the vertical axis of its symmetry matches the axial plane of symmetry of the vertical discrete zone of the soil continuum, previously arranged in the space of the soil continuum with a treatment tool of the soil-cultivating tool with passive actuators. In 20-30 years the cycle is repeated by means of the specified sequence of soil treatments. Treatment is carried out with displacement in the vertical plane circumscribed with the treatment tool of the soil-cultivating tool with passive actuators in the space of soil continuum by 1/3 of the distance between tillage lines selected when performing the first cycle of soil treatment. Cycles of soil treatment by the soil continuum are closed in 60-90 years and are continued in the same manner.
