WORKING BODY FOR TILLAGE Russian patent published in 2022 - IPC A01B35/16 A01B35/28 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. The working body for tillage is made in the form of a ring located at an angle to the direction of movement, having the shape of a truncated cone (1), connected to the hub (2). The truncated cone (1) is made sectional of spring steel, at the ends of which holes (3) are made with the possibility of bolted connection through brackets with holes (4) of the toothed spherical disk (5) located along its edges at a distance not less than the height of the tooth of the toothed spherical disk (5). The edges (6) of the teeth of the toothed spherical disk (5) are located in a plane passing through the larger diameter of the truncated cone (1). The brackets consist of two ribs (7), which are parallel in the upper part and rigidly connected to each other by upper plates, in the center of which there are holes coaxial with the holes (4) in the toothed spherical disk (5) and the adjacent surfaces of which correspond to the surfaces of the toothed spherical disk (5) at the place where the brackets are attached. In each bracket, the length of the upper part of the ribs (7) is equal to the width of the top plate. The upper and lower parts of the ribs (7), mated with each other, are located at an obtuse angle to each other. The lower parts of the ribs (7) are rigidly interconnected by the bottom plate, which has two holes along its central axis, coaxial with the holes (3) of the truncated cone (1). The inner surface of the truncated cone (1) is in response to the adjacent surface of the bottom plate.

EFFECT: reduced labor intensity of repair and improved quality of tillage.
