Energy-saving foundation pit dredging equipment for house building

The invention discloses energy-saving foundation pit desilting equipment for house building, and relates to the technical field of desilting equipment, the energy-saving foundation pit desilting equipment for house building comprises a bottom plate, a mounting plate is fixedly connected to the center of the upper surface of the bottom plate, a pump body is fixedly connected to the center of the upper surface of the mounting plate, and a silt suction pipe is fixedly connected to the input end of the pump body. When the dredging device is used, entering sludge is smashed under the action of an anti-blocking device, garbage impurities and the like are prevented from blocking a dredging box, when the sludge enters a dredging hose through the dredging box, a rotating rod is driven to rotate under the action of an impeller, connecting plates on the two sides start to rotate, and impurities on the outer sides of nylon nets on the two sides of the dredging box are cleaned; and meanwhile, the crushing cone on the conn
