AGRICULTURAL IMPLEMENT WITH ELECTRO-HYDRAULIC CYLINDERS Russian patent published in 2018 - IPC A01B73/00 

FIELD: agriculture; machine building.

SUBSTANCE: agricultural implement comprises a tongue, a frame with sowing sections, markers and an autonomous electromechanical hydraulic cylinder assembly, operably connected to each of the markers for extending and retracting the markers relative to the frame. Electromechanical hydraulic cylinder assembly comprises a cylinder with a rod including a piston moving in a housing. Also included in the assembly is a hydraulic fluid reservoir, operably connected to the cylinder and containing a hydraulic fluid, an electric pump operably connected to the reservoir, to direct the hydraulic fluid from one side of the cylinder piston to the other to move the rod, and an electrical control unit. Latter is operably connected to the agricultural implement for driving the electromechanical hydraulic cylinder assembly manually or automatically by means of a system, which includes a control unit for obtaining control signals related to operation, ISOBUS, and a hydraulic control unit connected thereto.

EFFECT: use of the invention will reduce the loss of power of hydraulic fluid by eliminating hoses from the hydraulic system of the tractor.
