suction, the oil sucked is by oil-suction oil filter 2 suction pump body, discharged by the oil-out of oil pump 10, fluid enters in valve plate by the flexible pipe that oil pump 10 is connected with valve plate, the first electromagnetic valve 15 is arrived again by check valve 13, when coil DT1 and DT2 of the first electromagnetic valve 15 must not be in the case of electricity, the hydraulic oil middle position (the first electromagnetic valve 15 P hydraulic fluid port when middle position by the first electromagnetic valve 15, B hydraulic fluid port and T hydraulic fluid port communicate) return to fuel tank 1, so can realize the non-loaded startup of motor 8.nullWhen the first electromagnetic valve 15 coil DT2 obtains electric,Then hydraulic oil can arrive P hydraulic fluid port (the second electromagnetic valve 16 P hydraulic fluid port when middle position of the second electromagnetic valve 16,A hydraulic fluid port and B hydraulic fluid port communicate),The A hydraulic fluid port of the second electromagnetic valve 16 is connected with the rod chamber of shoveling oil cylinder 11 by high-pressure hose,Its B hydraulic fluid port is connected with the rodless cavity of shoveling oil cylinder 11 by high-pressure hose,So hydraulic oil can arrive rod chamber and the rodless cavity of shoveling oil cylinder 11,Rod chamber and rodless cavity pressure now are equal,But the active area of rodless cavity is more than the area of rod chamber,F (power)=PxS (pressure x area) is calculated according to formula,So the power of rodless cavity output is more than the power of rod chamber output,The piston of shoveling oil cylinder 11 can move towards rod chamber direction,The hydraulic oil of the P hydraulic fluid port of the second electromagnetic
