The utility model provides dredging equipment capable of walking underwater, and belongs to a sludge removing device. The dredging equipment comprises an equipment body which is a closed shell, a sludge inlet is formed in the bottom of the equipment body, two grid-type driving belts are symmetrically arranged on the outer wall of the equipment body, and the grid-type driving belts are driven through a driving shaft. A driving mechanism and a sludge pump are arranged inside the equipment body. The driving mechanism is connected with the driving shaft, the sludge pump is connected with a sludge delivery pipe, and the upper end of the sludge delivery pipe stretches out of the equipment body. The dredging equipment further comprises a console which is electrically connected with the driving mechanism and the sludge pump respectively through lines. The dredging equipment is simple in structure, reasonable in design, capable of being widely applied to removing of sludge of ponds, reservoirs and city moats and capable of conducting operation quickly, efficiently and uninterruptedly in a low-energy-consumption mode. Water in the ponds does not end to be thoroughly pumped out, blockage cannot occur, the sludge pumping concentration is high and good practicability is achieved.
