FIELD: machine building.
SUBSTANCE: invention relates to hydraulic actuators of working members of scrapers. Hydraulic system comprises pump, tank, filter, three-section hydraulic distributor, each section of which is connected to one of bucket drive actuating hydraulic cylinders, rear wall, front shutter, controlled check valve and pipelines. Hydraulic cylinder rod cavity of additional front flap is connected to front shutter control section. Hydraulic cylinder rod cavity of additional front flap is connected to front shutter hydraulic cylinder rod cavity. Hydraulic cylinder blind cavity of additional front shutter via check valve is connected to hydraulic cylinder rod cavity of bucket unloading and to output of discharge valve, which is connected with blind side hydraulic cylinder of front shutter with its input.
EFFECT: providing independent control of two hydraulic cylinders from one section of standard hydraulic control valve.
