WORKING BODY OF THE TILLAGE MACHINE Russian patent published in 2023 - IPC A01B35/20 

FIELD: agriculture and forestry.

SUBSTANCE: invention relates to agriculture and forestry, in particular, to milling tillage tools with working bodies rotating from the drive. The working body of the soil-cultivating machine contains a disk with a horizontal axis of rotation, on which knives are fixed. A bushing is installed on the drive shaft of the machine, which has a keyed connection with it. The sleeve contains a flange in the form of a cam, the protrusions of which abut against the rollers located at one end of the two-arm levers mounted on axles fixed on disks with knives that can freely rotate on the driven shaft of the machine. The other end of the two-arm levers is connected to a pre-stretched spring.

EFFECT: invention will provide an increase in structural and functional reliability to ensure protection against breakage of the working bodies and mechanisms of the tillage machine during overloads with a relatively simple design.
