An inlet of the dredge pump communicates with one end of a dredge pipe, and an outlet of the dredge pump is connected with one end of a mud discharging pipe. The other end of the mud discharging pipe communicates with the interior of the energy dissipation tank. One end of the mud delivery pipe is a free end, and the other end of the mud delivery pipe is connected with one of the mud outlets in the energy dissipation tank. The mud delivery pipe is sleeved with a plurality of floating bodies with buoyancy in the axial direction, and the floating bodies are in clearance fit with the mud delivery pipe. The mud delivery pipe is made of a non-magnetic material. Each floating body is internally provided with a cavity, and electromagnets are arranged in each cavity and located at the two ends of the corresponding floating body. A limiting block is further arranged at the free end of the mud delivery pipe. The dredger of the improved structure has the advantage that the space of the mud bin can be fully utilized through the mud delivery pipe.
