When the mesh cover mechanism 4 is replaced and maintained, the mesh cover body 401 is pressed toward the inside of the splicing seat 301 to move the limit block 402 out of the slot 306 and rotate the mesh cover body 401 to move the limit block 402 to the position of the buffer spring 204. The mesh cover body 401 is removed, and a new mesh cover mechanism 4 is selected to insert the limit block 402 along the movable slot 304 into the bottom of the movable slot 304, and the mesh cover body 401 is rotated to move the limit block 402 to the position of the slot 306.

Clean to prevent debris from adhering to the surface of the mesh cover body 401 and causing blockage. At the same time, as the scraper 202 rubs against the mesh cover body 401 and wears, the first pressure spring 203 pushes the mounting seat 205 to make the scraper 202 always contact with the surface of the mesh cover body 401.
