A known design of tillage tools with variable cutting angle of the knife, which includes a shaft carrying the disk, knives, and also provided with an additional shaft with firmly planted on him by the gear, a bracket rigidly mounted on the main shaft mounted in the mounting of the worm gear, with the drive to drive, and regulating gear, with additional shaft one end of which is installed in the hole of the disk, and the other in securing and regulating gear mounted on the main shaft for rotation with respect to it when interacting with the gear mounted on an additional shaft (EN, 2224393, MPK AV 33/02, 33/16, publ. 27.02.2004,).
The disadvantage of tillage cutter is a need to use one section of the knives of several toothed wheels, which greatly complicates the design.
The technical result is to simplify the design of the cutter and the reduction of power for milling.
The technical result is achieved in that the working body of tillage cutter contains the blades and the main shaft, which is rigidly fixed two drove between them in their about is the holes adjustably mounted three pressurebuy is rigidly mounted blades. At the ends pressurenow rigidly fixed satellites connected gear with a sun gear located on the main shaft and rigidly connected to the housing.
The working body of tillage cutter illustrated by drawings: figure 1 shows the working body of tillage cutter; figure 2 - section of the planetary mechanism.
The working body is (1) from the main shaft 1 and 2 knives. On the main shaft 1 is rigidly fixed two drove 3 and 4, between which in their holes movably, for example, with the sleeves 5 are three pressurebuy 6 is rigidly mounted blades 2. At the ends pressurenow 6 rigidly with dowels 7 (2) fixed satellites 8, United gear with a sun gear wheel 9, which is located on the main shaft 1 and is rigidly connected to the housing 10.
The device operates as follows. Torque from the main shaft 1 is transmitted cage 3, resulting in a rotation of pressurebuy 6 with 2 knives around its own axis and the axis of the main shaft 1 due to the rigidly mounted on them satellites 8. When the device is a knife in the soil follows the path of trochoidea change the cutting angle and thereby decreases the power of resistance in the soil.

SUBSTANCE: invention refers to agriculture, in particular, to land reclamation. The method includes deep tillage of soil with soil cultivating tools with passive actuators, rotor-milling treatment of internal soil layers, which is carried out 2-5 years after deep tillage of soil with soil cultivating tools with passive actuators. Soil treatment is carried out in cycles, cycle components include deep tillage of soil with a soil-cultivating tool with passive actuators for depth of 45-50 cm with a pitch of vertical plane circumscribed by the treatment tool in the space of soil continuum, multiple to minimum distance between lines of plants of future agrophytocenosis, for instance, 45 cm, 70 cm, 110 cm. 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.
