A dust hood 203 is vertically arranged on the upper end of the stand 201, and the dust hood 203 covers the grinding disc 100, a protective cover 202 is arranged at the lower end of the dust hood 203, and the protective cover 202 is retractable and detachable to cover the grinding disc 100. A filter screen 206 is arranged horizontally inside the lower end of the dust hood 203, and the filter screen 206 can filter the slag dust flying in the grinding process, and the larger particles will adhere to the filter screen 206. A knocking component 207 is arranged on the upper surface of the filter screen 206, and the knocking component 207 can be used to knock the larger particles attached to the lower surface of the filter screen 206 and re-grind them in the grinding disc 100. The upper end of the dust hood 203 is connected to a fan 204, and the fan 204 can suck away the dust;

[0023] The knocking component 207 includes a driving electric cylinder 2075 installed on the middle upper surface of the filter 206. A plurality of rotating plates 2074 are arranged on the circumference of the upper end of the driving electric cylinder 2075. The rotating plates 2074 can be driven by the driving electric cylinder 2075 to rotate simultaneously. A spherical block 2076 is arranged at the lower end of the rotating plate 2074, and the spherical block 2076 can contact the upper surface of the filter 206.

[0024] In this embodiment, preferably, a stabilizing plate 2071 is horizontally arranged on the upper surface of the filter 206, and the stabilizing plate 2071 is fixed on the upper surface of the filter frame 206. The driving electric cylinder 2075 is vertically installed on the upper surface at the center of the stabilizing plate 2071. A disc 2073 is arranged on the upper end of the piston rod arranged inside the driving electric cylinder 2075, and a plurality of lugs are arranged on the circumferential surface of the disc 2073. A rotating shaft is arranged between the upper end of the rotating plate 2074 and the lugs, and as the disc 2073 moves upward, the rotating plate 2074 can be driven to rotate.

[0025] In this embodiment, preferably, a vertical plate 2072 located on the inner side of the rotating plate 2074 is vertically arranged on the upper surface of the stabilizing plate 2071, and the vertical plate 2072 can support the rotating plate 2074.
