WORKING BODY FOR SOIL TREATMENT Russian patent published in 2017 - IPC A01B29/04 A01B39/08 A01B39/18 

FIELD: agriculture.

SUBSTANCE: working body includes a conical ring made of a rectangular strip, spokes connecting the conical ring and the hub. There is a ring in the form of a torus installed against the inner surface of the small diameter of the conical ring behind the spokes. In the process of operation, the soil adheres to the cavity between the torus ring and the inner surface of the conical ring, forming an additional slope, which creates the conditions for the rapid release of soil from the inner surface of the conical ring.

EFFECT: increased reliability and durability of the conical ring by increasing its rigidity while ensuring full deweeding and reducing the amount of dust during the ring operation.
