WORKING ELEMENT OF AGRICULTURAL MACHINE, HAVING PRESSURE CONTROL SYSTEM Russian patent published in 2020 - IPC A01B63/26 A01C7/20 

FIELD: agriculture.

SUBSTANCE: working element of agricultural machine and agricultural machine containing working element, intended for installation on essentially horizontal beam of machine by means of deformable connecting structure, containing at least one upper lever and at least one lower lever. Connection structure comprises a clamp pressure adjustment system having a movable mechanism and a base member. Movable mechanism contains a lever and an elastic element. Lever is installed with possibility of rotation relative to resilient element around first axis. Moving mechanism enables the engagement state in which the movable mechanism is pressed to the base member; movable mechanism can receive at least one working position, in which the adjustment system pressures the working element; and adjustment state, in which the movable mechanism can move relative to the base member about the lower axis. Movable mechanism comprises a second axis different from the first axis, and the movable mechanism is configured to achieve an intermediate state, in which lever can rotate about second axis.

EFFECT: simplified design, efficiency and ease of use.
