At the same time, under the pushing effect of the plug plate 310 and the limiting effect of the suction pipe 301, the two second push plates 309 and the first push plate 308 move synchronously toward the fixed plate 303, thereby pushing the sludge to move toward the pipe opening of the suction pipe 301, and then being sucked into the collection box 101. Step 3: After completing the dredging here, turn off the suction pump, drive the rotating screw 300 to rotate in the opposite direction through the motor 304, so that the first push plate 308 drives the two second push plates 309 to move towards the direction close to the connecting box 302, and use the walking mechanism 100 to drive the dredging mechanism to move, and repeat the above steps 1 and 2.
