WORKING BODY OF CULTIVATOR Russian patent published in 2021 - IPC A01B49/00 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to agricultural engineering, in particular to the working bodies of cultivators for surface tillage, heavily weedy vegetation, and can be used to prevent the hanging of plant residues on the racks of the working bodies of cultivators and other tillage tools. The working body of the cultivator includes a freely rotating disc knife installed in front of the stand of the cultivator share in alignment with it with the ability to adjust the depth of immersion in the soil. The disk knife is attached directly to the stand of the cultivator paw and is made in the form of a flat disk, on which replaceable triangular-shaped knives with a one-sided cutting edge on the side faces are bolted. The disc axis is pivotally fixed on a leash relative to the rack and is spring-loaded by an adjustable push rod. In this case, the disk has the ability to reinstall it on the hub by turning it 180° in the horizontal plane.

EFFECT: invention will reduce the traction resistance, increase the productivity and quality of soil cultivation by completely cutting weeds in the upper soil horizon, as well as exclude the overhanging of the stems on the stand and prevent the removal of wet soil to the cultivated surface.
