Abstract
The utility model relates to a wearproof sand pump, comprising a main shaft, an assembly of the main shaft, a back end cover, a pump case, a vane and a front end cover; wherein, a taper inlet is provided on the front end cover with the taper of 1-20 degrees; an arc stopper is arranged on the back end cover. A circular concave guard plate is disposed on an internal surface of a pump case of the back end cover and an edge boss using for assembling a circular concave guard plate is positioned on the back end cover. A shaft sleeve of the vane on an end of the main shaft is assembled with a loose collar. Mounting holes on the end covers are long holes and the pump case adopts the relevant structures of a long hole, a circular hole, a T-shaped hole and a pre-built nut. Mounting holes of the end covers are the circular holes and the pump case adopts the relevant structures of a long hole, a circular hole, a T-shaped hole and a pre-built nut and has the advantages that all components of the pump adopt more reasonable new structures, so that the wear resistance is better, the service life is longer, the wearing parts are easier for changing and the work efficiency of dredging and sand quarrying.
