[0040] Embodiment two

[0041] As shown in Figure 7 In comparison with the first embodiment, another embodiment of the present application is that the two ends of the scraper 2 are rotatably connected with the rollers 101; the rollers 101 contact the connecting plate 51; when the scraper 2 moves, the rollers 101 rotate to contact the connecting plate 51, so that the scraper 2 smoothly moves, the rotation of the rollers 101 provides smooth movement when the scraper 2 contacts the connecting plate 51, and the jamming between the scraper 2 and the connecting plate 51 is reduced.

After the scraper 2 resets, each brush 61 moves between a pair of dust removal plates 7. With the movement of the brush 61, the separation plate 62 pulls the first limiting ball 72, drives the first elastic rope 71 to deform and pull, and after the elasticity of the separation plate 62 is smaller than the pulling force of the first elastic rope 71, the first limiting ball 72 rebounds, causing the brush 61 to vibrate. When the separation plate 62 rotates under the pulling of the first elastic rope 71, the buffer plate 82 installed on the side wall of the second rotating shaft 8 rotates to contact and impact the plurality of blocking plates 83, so as to form a jerk feeling. In the rotating process of the separation plate 62, the second elastic rope 91 moves in the sixth sliding groove 9 under the pulling condition,The plurality of second limiting balls 93 are impacted.
