FIELD: earth-moving machines.
SUBSTANCE: invention relates to construction and road machines, namely to earth-moving machines of bulldozer type. Earth-moving machine comprises basic machine, pushing bars and working element including accumulation tank formed by cutting and guide plates, side and rear walls and lifting unloading bottom with hydraulic drive. Working equipment drive hydraulic cylinders are connected by hydraulic lines via hydraulic control valve and hydraulic throttle with hydraulic accumulator, hydraulic pump and hydraulic tank. Earth-moving machine is equipped with support rollers of working equipment and lifting bottom of accumulation tank installed on rollers in horizontal and vertical guides. Support rollers with swivels are installed on ends of levers pivotally attached to pushing bars, and the second ends of levers are pivotally connected to rods of hydraulic cylinders of working equipment.
EFFECT: higher efficiency, reduced power consumption and simplified process control.
