Desilting pump

Abstract

The invention discloses a desilting pump. The desilting pump comprises a desilting mechanism as well as left and right stirring mechanisms, wherein the desilting mechanism comprises a pump shell, the bottom end of the pump shell is provided with a silt inlet which is fixedly connected with a silt inlet barrel, a main shaft is rotatably mounted in the pump shell, an impeller is mounted on the main shaft, a stirrer is mounted on the lower end of the main shaft, an annular channel is arranged inside the pump shell, one side of the pump shell is provided with a silt outlet, each of the left and right stirring mechanisms comprises a motor, a connecting pipe and a stirring shaft, the stirring shaft is rotatably mounted in the connecting pipe and is in driving connection with the motor, the lower end of the stirring shaft is fixedly connected with a positioning pillar, a plurality of stirring blades are arranged surrounding the positioning pillar, each stirring blade inclines downwards and is downward-sunk-arc-shaped, a plurality of stirring teeth are fixedly connected to the bottom end of each stirring blade, and the tooth end of each stirring tooth is wedge-shaped. The desilting pump is reasonable in structure, the work efficiency and normal work are guaranteed, damage is seldom caused, the silt ground with hard texture can be broken, and the work efficiency and the desilting effect are improved.

Description

technical field [0001] The invention relates to the field of engineering vehicles with dredging function, in particular to a dredging pump assembled on the engineering vehicles. Background technique [0002] The dredging pump is a part of a specific engineering vehicle, which plays the role of dredging. When the existing dredging pump is performing dredging operations, the sludge directly enters the pump casing through the silt inlet, and the relatively hard or insoluble substances in the sludge can easily cause blockage of the pump body, thereby affecting the normal operation of the pump body, seriously will damage the pump body. In addition, the stirring mechanism of the existing dredging pump includes a stirring shaft and stirring blades fixedly connected around the bottom of the stirring shaft. The dredging effect is poor, and it cannot meet the needs of actual use. Contents of the invention [0003] The object of the present invention is to provide a dredging pump ...
