DISC SOIL-TILLING SECTION Russian patent published in 2023 - IPC A01B7/00 A01B21/08 A01B35/16 

FIELD: agriculture.

SUBSTANCE: disk soil-tilling section consists of inclined disks and bearing supports rigidly fixed on the shaft. The disks are made in the form of polygons inscribed in an ellipse. The major axis of the ellipse is inclined to the axis of rotation of the shaft at an angleα =arcsin(b/a), where b is the semi-minor axis of the ellipse; a is the semi-major axis of the ellipse. Polygonal discs are rotated relative to each other around the axis of the shaft clockwise or counterclockwise by an angleβ =180k/(n-1), where n is the number of polygonal disks in the section, k is an odd number of periods of the total rotation of polygonal disks by 180 degrees.

EFFECT: improvement of quality and efficiency of tilling.
