[0033] The working principle of this utility model:

[0034] First, the staff can fix the device to the hull by means of bolts or other fixing methods, and extend the mud inlet pipe 3 to the specified position, and then extend the water outlet pipe 6 to the outside of the hull. When using the device, the baffle 22 is raised, and when the movable plate 16 is placed in the collection box 8, the two sides of the movable plate 16 will squeeze the limit block 20, so that the limit block 20 moves toward the inside of the groove 18, which is convenient for the staff to place the movable plate 16 into the collection box 8 through the hollow groove 23, and then loosen the baffle 22. At this time, the limit block 20 is in contact with the movable plate 16 to prevent the movable plate 16 from sliding out of the hollow groove 23 due to the vibration of the hull during dredging and mixing. After the baffle 22 is loosened, the baffle 22 will move down to a position abutting against the movable plate 16, thereby closing the other hollow spaces of the hollow groove 23 to prevent the sludge from flowing out, and then the sludge pump 2 is turned on, and the sludge in the ditch is collected into the collecting box 8 by the sludge pump 2. At this time, the moisture in the sludge will pass through the filter screen 11 and flow to the water inlet pipe 7 through the action of the inclined plate 10, and then the water pump 5 is turned on. The water pump 5 can discharge the moisture flowing out of the sludge to the hull body, in order to prevent the sludge from losing water and causing The stirring motor 13 can be turned on to drive the stirring shaft 14 to rotate, and the stirring shaft 14 drives several groups of stirring blades 15 to rotate, so as to achieve the stirring of the sludge, so that the sludge is in a loose state, which is convenient for subsequent cleaning. When the sludge in the collecting box 8 is enough, the hull will be docked at this time, and the sludge in the collecting box 8 will be cleaned, which is convenient for subsequent dredging work. At this time, the staff can discharge the sludge through the space above the collecting box 8. When there is still some sludge at the bottom of the collecting box 8, the baffle plate 22 can be moved up, and then the limit block 20 can be pressed to move the limit block 20 toward the groove 18, and then the movable plate 16 can be taken out by the handle 17. Since the height of the hollow groove 23 is greater than the height of the movable plate 16, it is convenient to take out the movable plate 16 and part of the sludge attached to the surface of the movable plate 16, which is convenient for the treatment of the sludge and the cleaning of the surface of the movable plate 16, improves the cleaning effect, and is convenient for subsequent use.
