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

FIELD: agriculture.

SUBSTANCE: device contains a frame with cross rails, where frontally racks with discs are mounted across the width of grip and forming rows. Discs are made of convex-concave shape and mounted with the ability of rotation and with angle of attack. Disk axis are tilted to the plane of the soil surface, which is close to horizontal one at an acute angle so that the convex side is turned towards the soil surface. In each subsequent row the discs are displaced in the transverse direction relative to the discs of the previous row on the value of Δ, equal to the quotient of inter-range space for the number of rows. In each row, one half of the discs is inserted in one direction, while the other half is in the opposite direction, i.e concave or convex sides, respectively, in the opposite direction. Discs of each subsequent row are set in the opposite direction with respect to discs of the previous row. The distance centers between the nearest disks of one row located in the opposite direction are shifted on the value of Δ from row to row.

EFFECT: such constructive implementation enables to improve quality of soil due to a uniform distribution of treated soil on the width and depth, and to ensure uniformity of the soil structure.
