Submersible sand discharge electric pump with crushing plant

The utility model relates to a submersible sand discharge electric pump with a crushing plant. The crushing plant is arranged in an inner cavity at the lower end of a pump body. The crushing plant consists of a semiopen impeller and a cutting board. The impeller comprises an S-shaped blade and a rear cover board. The lower surface of the impeller is provided with the cutting board on which a plurality of water inlet holes are drilled. The lower surface of the cutting board is provided with a stirring wheel connected with the end part of a rotor shaft. The submersible sand discharge electric pump with the crushing plant has the characteristics that when the stirring wheel rotates, solid matter such as long fibered objects, crushed ores and the like and liquid can be stirred. Under the harsh working conditions of mine, construction, agriculture and like, after a crushing pump is adopted, different types of solid matter such as the long fibered objects, the crushed ores and the like in a water pit of a mine can
