Therefore, the subsequent use influenced by a large amount of chalk dust remained on the sponge block 3 can be avoided.
When the brush block 75 moves up and down, the brush block 75 also drives the rotating shaft 84 to move up and down, the rotating rod 61 moves up and down to drive the second gear 82 to move up and down, due to the action of the torsion spring 83, the second gear 82 moves up and down through the continuous positive and negative alternate rotation of the tooth block 85, the positive and negative alternate rotation of the second gear 82 drives the positive and negative alternate rotation of the rotating shaft 84, the positive and negative alternate rotation of the rotating shaft 84 drives the linear hole plate 81 to rotate positively and negatively, the positive and negative alternate rotation of the linear hole plate 81 beats the bristles on the brush block 75, and the residual chalk dust on the brush block 75 is removed. When the brush block 75 stops moving up and down, the brush block 75 stops driving the second gear 82 to move up and down through the rotating shaft 84, the second gear 82 stops rotating forward and backward alternately, and the linear orifice 81 stops rotating forward and backward alternately. Thus, the subsequent use of the brush block 75 can be prevented from being affected by a large amount of chalk dust remaining thereon.
Referring to fig. 1, 2, 4 and 7, the device further comprises a collecting box 9, an L-shaped plate 10 and a magnet 11, wherein the L-shaped plate 10 is fixedly connected to the lower portion of the outer rear side surface of the u-shaped shell 51, the magnet 11 is fixedly connected to the inner rear side surface of the L-shaped plate 10, the collecting box 9 is slidably arranged at the bottom end of the u-shaped shell 51 and communicated with the u-shaped shell, and the collecting box 9 is in contact fit with the magnet 11.

When the removed chalk dust falls out through the hole of the u-shaped shell 51, the chalk dust falls into the collection box 9. When a proper amount of chalk dust is filled in the collecting box 9, the collecting box 9 can be pulled to move forwards to be separated from the magnet 11, when the collecting box 9 is separated from the u-shaped shell 51, the chalk dust can be poured into the garbage can, after all the chalk dust is poured out, the collecting box 9 is placed back to the u-shaped shell 51, and the collecting box 9 is contacted with the magnet 11 and is sucked and fixed. Therefore, the chalk dust can be prevented from falling to the ground to influence the surrounding environment.
When the line-shaped pore plate 81 rotates forwards and backwards alternately, the line-shaped pore plate 81 rotates forwards and backwards alternately to drive the guide blocks 12 to rotate forwards and backwards alternately, the guide blocks 12 rotate forwards and backwards alternately continuously to slide back and forth, the guide blocks 12 slide to drive the iron balls 13 to slide, when the iron balls 13 slide to be in contact with the line-shaped pore plate 81, the iron balls 13 knock and vibrate the line-shaped pore plate 81, and chalk dust on the line-shaped pore plate 81 is vibrated and dropped. When the linear orifice 81 stops rotating forward and backward alternately, the guide block 12 stops driving the iron ball 13 to slide. Thus, the linear orifice plate 81 can better remove the chalk dust on the brush block 75.
