When the fixed gear 10 rotates, the two racks 11 can drive the two connecting rods 12 and the first blackboard 13 to move relative to each other, and drive the corresponding moving blocks 22 to slide relative to each other in the two moving grooves 3. Since the two sides of the two first blackboards 13 are wedge-shaped, the two first scrapers 25 can fit with the second elastic telescopic rod 24 under the action of its own elastic force, and can slide onto the first blackboard 13 to clean it. When the two first blackboards 13 move relative to each other, the two fixed blocks 14 can be driven to move relative to each other synchronously, so that the two rotating rods 15 can rotate relative to each other and open, and drive the two connecting blocks 16 and the second blackboard 17 to move forward in the groove 2, and the second blackboard 17 can drive the dovetail block 28 to move forward in the dovetail groove 29; The third elastic telescopic rod 26 can drive the second scraper 27 to fit with the second blackboard 17 under the action of its own elastic force, and when the two first blackboards 13 move relatively, the two second scrapers 27 can automatically clean the second blackboard 17; The second bevel gear 7 at the bottom can drive the third rotating shaft 18 and the cam 19 to rotate continuously, and the cam 19 can intermittently hit the vibration plate 21 when rotating, and the vibration plate 21 can rebound under the elastic force of the first elastic telescopic rod 20, so that the vibration plate 21 can intermittently hit the mounting base 1, so as to shake off the dust adhering to the first blackboard 13 and the second blackboard 17; The motor 4 is started in the reverse direction, so that the above movement is reversed, the second blackboard 17 is restored to its original state, and the two first blackboards 13 can be in a mutually attached state; At the same time, the second bevel gear 7 located in the front can drive the second rotating shaft 8 and the fan blades 9 to rotate, and then under the action of negative pressure, the dust collection box 34 can absorb the dust generated by cleaning into the fixed pipe 33, and can fall into the collection box 36 in the dust box 32 for centralized collection, and the excess air can be discharged from the one-way air outlet valve 35, so as to maintain the air pressure balance inside the dust box 32, and finally the collection box 36 can be opened to further process the collected dust.

[0029] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
