After the closing piece 14 rotates, it completely fits with the inner wall of the suction pipe to be closed. The closing piece 14 is disc-shaped, which can prevent the water source from flowing to the pipes on both sides when spraying water. At this time, the block 18 is aligned with the docking groove 17 and the pull ring 21 is released. The reset spring rebounds, and the block 18 rises to the inside of the docking groove 17 and cannot be moved and adjusted. On the contrary, when it needs to be opened for vacuuming , just repeat the above operation in reverse, which is convenient for the staff to divide the area, fill the water tank 22 with water through the water inlet pipe, and then start the electric sprinkler 23 to spray the water source along the branch pipe to the inside of the suction pipe, flushing the fine dust adhering to the dustproof net 12 and the fine dust floating in the pipe, and then open the solenoid valve 11, and the sewage enclosed in the area between the two sets of closing pieces 14 will fall down into the inside of the recovery box 5 due to gravity along the passage after the solenoid valve 11 is opened, so that there will be no more dust flying during centralized discharge. By checking the scale bar printed on the observation window 8 on one side of the recovery box 5, it can be judged At this time, if the amount of sewage is too much, in order to prevent the sewage from entering the inner side of the bellows 28, the valve 7 can be opened to allow the sewage to be discharged along the discharge pipe 6. Starting the second motor can drive the threaded rod 25 to rotate, so that the adjustment block moves along the adjustment groove on the inner side of the adjustment frame 24, and then drives the blade cleaning assembly close to the cutting knife 4. After one side of the cutting knife 4 is stuck between the two sets of sponge brushes 27, the first motor is started to drive the cutting knife 4 to rotate slowly counterclockwise. The debris on the blade is wiped off by the sponge brush 27, flows to the inner side of the guide funnel 29, and then falls into the inner side of the recovery box 5 along the bellows 28 for collection.
