HYDRAULIC FLOW DRIVEN BY PUSHING FORCE OF AUTOMOTIVE TRACTOR Russian patent published in 2015 - IPC A01B3/46 A01B15/14 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agricultural engineering, in particular to the semi-mounted ploughs. The hydraulic plough comprises a chassis (1) mounted on at least four bearings (2). On each bearing (2) two twin wheel are mounted, rotating by 360°. Through the transverse axes the wheels are evenly distributed for stability of the structure. The transverse axes are in the front (15) and the central zone. In the central zone also a vertical tripod (3) is located for engagement with the tractor. At the base of the tripod (3) the hub (4) of electric valves and rotary device are located. The rotary devices comprise tubes (5) for transmission of fluid, connected with one end to the vehicle and with the other end with the hub (4) of electric valves, and further with the hydraulic cylinders (6) of the mouldboard controls (13), hydraulic cylinders (7) of controlling the treatment depth and the height of the plough, the hydraulic cylinders (8) of widening the track of the central wheels and the hydraulic cylinders (9) for the transfer of the plough to the transport position.

EFFECT: constructive solution is aimed at providing fast, efficient and cost-effective ploughing.
