DISK SOIL-FORMING SECTION Russian patent published in 2017 - IPC A01B15/16 

FIELD: agriculture.

SUBSTANCE: disk soil-forming section contains a bearing assembly with a rack and the shaft. On the shaft on one side of the bearing assembly, two needle disc set, the plane of which is perpendicular to the axis of the shaft. On the other side of the shaft, the spherical disc is fixed with cutout. The spherical disc is facing the convex sphere and a bearing assembly mounted within the plane of the blade to the shaft axis, and the maximum tilted disk portion opposite the notch located tangentially. The rear edge of the cutout has been rejected by an angle of up to 30° from radius to the point of its edges on the blade in the rotational direction. The angle of deviation of the radius of the rear edge does not exceed 20°. Between the bearing assembly and the spherical disc, the needle disk is installed. The vertical shaft section and the rotation axis of disc axis lie in one plane.

EFFECT: increase the capacity of water-detention of cut furrows, preventing the clogging of the cut disc crop residues, increased section width.
