UNIT FOR SOIL TREATMENT AND MAKING CAVITIES IN THE SOIL Russian patent published in 2018 - IPC A01B45/02 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to the field of agricultural engineering, in particular to a soil cultivation plant for creating cavities in the soil. Device comprises a machine frame that can move in the direction of travel, and at least one drive unit that is mounted in the machine frame and moves at least one pivotally mounted digging tool fore and aft in a substantially vertical direction. With a digging tool, a return device is connected, that consists of a piston / cylinder assembly with a spring element acting on the piston rod of the piston / cylinder assembly, which moves the digging tool after exiting the soil back to its original position. At the outer free end of the piston rod, there is at least one laterally projecting flange that is at least one axially opposite axially disposed on the piston-side end of the cylinder assembly, a mating flange and with at least one attached flange against each other to one or the other flange by the damping element, forms a damping device that dams the impact of the digging tool on the machine frame when colliding with the initial setting stop.

EFFECT: such a design solution provides easing of impacts on the machine frame.
