[0047] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0048] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

Under the transmission of the driven gear 15 and other structures, the grinding wheel is finally driven to perform grinding.

The top of the side rod 23 is equipped with an arc-shaped protrusion 22, and the top of the arc-shaped protrusion 22 has an arc surface structure that is adapted to the linkage frame 18.

[0067] By setting up the extrusion component, while the conveyor chain assembly 6 is moving, the arc-shaped protrusion 22 can be used to extrude the linkage frame 18, and then the lifting frame 19 can be used to extrude the elastic bag 21 to achieve airflow output and achieve the purpose of cleaning debris.
