DISC TILLAGE TOOL Russian patent published in 2010 - IPC A01B21/08 

FIELD: agriculture.

SUBSTANCE: tool contains a hitch and a frame. On the frame spherical discs are mounted on stand-alone racks with symmetrical rows, diverging from the longitudinal axis of the tool symmetry. Spherical discs have the angle of attack and angle of slope to the vertical plane. The discs are installed in rows so that each successive longitudinally disc is displaced relative to the previous disc in such a way that shifts soil in the furrow of the previous one. The total number of discs in symmetrical rows is equal to N, where the number of rows of disks is even. One part of the disks in the amount of is turned with its concave part of the sphere to the axis of the tool, while the other part of the discs in the amount of is turned with the convex part of the sphere to the axis of the tool. At the functional level such placement of disks in rows provides shift of soil with the first part of the disks to the axis of the tool, and the second - shift of soil from the axis of the tool. N, n1, n2 are the even numbers, n1+n2 = N, and the minimum value of N is equal to double number of rows of the tool discs.

EFFECT: this constructive implementation enables to improve the quality of soil, the tool road-holding ability and to reduce energy consumption.
