Abstract
An forward and integral reversing device for screw sand delivering machine belonging to direction-changing control area, which comprises a variable-flow hydraulic pump, an electrohydraulic servo valve, a potentiometer, an electrohydraulic direction-changing valve, a variable-flow hydraulic fluid motor, a shaft coupling, a screw sand delivering machine, and a selector switch. The variable-flow hydraulic pump can apply bidirectional or unidirectional variable-flow hydraulic pump. When the bidirectional variable-flow hydraulic pump is applied, the oil outlet of the bidirectional variable-flow hydraulic pump is controlled by the control of electrohydraulic servo valve by the selector switch, which makes the packing auger shaft rotate forwardly and integrally. When the unidirectional variable-flow hydraulic pump is applied, the forward or integral rotation of the variable-flow hydraulic fluid motor by the control of electrohydraulic servo valve by the selector switch, which makes the packing auger shaft rotate forwardly and integrally. The forward rotation is the normal work, while the integral rotation is to clean the screw sand delivering machine. Meanwhile, via changing the swash plate angle of the variable-flow hydraulic pump, the hydraulic flow capacity of the variable-flow hydraulic pump has a linear change, and the revolution rate is continuous and adjustable. The utility model solves the problem that the screw sand delivering machine is blocked, the intensity of labor to clean the screw sand delivering machine is large, which may easily destroy the machine.
