Working principle: When the sound insulation board 2 needs to be cleaned, first pull out the pin 314 from the first rotating shaft 301 and the fixed plate 313, and then turn the handle 312. At this time, the handle 312 can facilitate the coal mine workers to rotate the swivel 302, and then the handle 312 will drive the fixed plate 313 to rotate in the same direction. At this time, the fixed plate 313 and the pin 314 can limit the swivel 302, and then the handle 312 will drive the swivel 302 to rotate along the arc surface of the first rotating shaft 301. At this time, the swivel 302 will drive the winding rope 303 to rotate, and then the winding rope 303 will drive the auxiliary ring 310 along the arc surface of the second rotating shaft 304. The auxiliary ring 310 can reduce the friction between the winding rope 303 and the second rotating shaft 304, and the second rotating shaft 304 can limit the moving path of the winding rope 303. Then the winding rope 303 will pull the connecting plate 305 to move upward. At this time, the connecting plate 305 will drive the cleaning box 306 to move, and then the cleaning box 306 will drive the scraper 307 to move in the same direction. At this time, the scraper 307 will drive the brush 311 to move in the same direction along the surface of the sound insulation board 2. At this time, the brush 311 can clean the sound insulation board 2 more deeply, and at the same time, the cleaning box 306 will drive the slider 308 to move along the slide groove 309 provided on the frame 1. The cleaning box 306 moves in the same direction. At this time, the slider 308 and the slide groove 309 can limit the movement path of the cleaning box 306, and then the coal dust cleaned by the brush 311 and the scraper 307 will fall into the cleaning box 306. At this time, the cleaning box 306 will initially collect the coal dust. When the cleaning box 306 drives the scraper 307 to reach the top of the sound insulation board 2, the handle 312 is turned in the opposite direction. At this time, the cleaning box 306 will move downward with the help of its own gravity. At the same time, the cleaning box 306 will drive the scraper 307 and the brush 311 to clean the sound insulation board 2 downward. When the cleaning is completed, the handle 312 is turned to drive the fixing plate 313 to rotate to a certain position, and the latch 313 is moved downward. 14 is inserted into the fixed plate 313 and the first rotating shaft 301, and the handle 312 and the rotating ring 302 are limited. By setting the cleaning device 3, with the help of the first rotating shaft 301 and the rotating ring 302 and the second rotating shaft 304 and the auxiliary ring 310 and the winding rope 303, it is more convenient to control the cleaning box 306 to drive the scraper 307 to move up and down to scrape the sound insulation board 2, and use the cleaning box 306 to collect the cleaned coal mine dust, thereby avoiding the phenomenon of large amounts of coal mine dust being raised when the coal mine workers are manually cleaning, thereby avoiding the coal mine workers from accidentally inhaling, protecting the health of the coal mine workers, and further improving the work efficiency.

When the coal dust cleaned up in the cleaning box 306 is poured out, the screw rod 45 is first rotated out from the screw hole 42 and the rotating plate 44, and then the screw rod 45 will drive one end of the connecting rope 46 to move in the same direction. At this time, the connecting rope 46 can prevent the screw rod 45 from being lost. When the screw rod 45 is separated from the rotating plate 44, the rotating plate 44 is rotated along the arc surface of the fixed shaft 43. When the rotating plate 44 is out of contact with the storage box 41, the storage box 41 is pulled out along the surface of the cleaning box 306. At this time, the storage box 41 will collect the coal dust in the cleaning box 306, and then the storage box 4 1 will drive the gasket 47 to move in the same direction. At this time, the gasket 47 can reduce the gap between the storage box 41 and the cleaning box 306. Then, when the storage box 41 is out of contact with the cleaning box 306, the coal dust in the storage box 41 is poured out. By setting the collecting device 4, the coal dust is collected by the storage box 41, and the screw rod 45 and the rotating plate 44 are used to limit the storage box 41, so as to avoid the situation that the coal dust in the cleaning box 306 is too much and difficult to pour out, so that the coal mine workers can conveniently pour out the cleaned coal dust, and further improve the work efficiency of the coal mine workers.
