A poking piece is arranged on one side of the poking shaft 301. An impact support 302 is arranged on one side of the poking shaft 301. The impact support 302 is fixedly connected with the dust removal shell 201. An L-shaped impact rod 304 is slidably connected to the lower part of the impact support 302. The poking shaft 301 can be in contact with the L-shaped impact rod 304. A plurality of springs 303 are fixedly connected between the L-shaped impact rod 304 and the impact support 302. A vibrating plate 307 is arranged below the L-shaped impact rod 304. The L-shaped impact rod 304 can be in contact with the vibrating plate 307. A cylindrical brush 308 is symmetrically arranged below the vibrating plate 307. The cylindrical brush 308 is rotatably connected with the dust removal shell 201. The filter screen belt 207 passes between the vibrating plate 307 and the cylindrical brush 308. Symmetrically arranged elastic columns 306 are fixedly connected to the vibrating plate 307 on both sides. A vibrating support 305 is fixedly connected to the other end of the elastic column 306. The vibrating support 305 is fixedly connected with the dust removal shell 201. Rotating rods are rotatably connected to both ends of the vibrating plate 307. The rotating shaft 206, the poking shaft 301 and the cylindrical brush 308 are connected through a synchronous belt. A dust collection box 309 is arranged below the cylindrical brush 308. The dust collection box 309 is slidably connected with the bottom of the dust removal shell 201. When the filter screen belt 207 needs to be cleaned, the rotating shaft 206 drives the filter screen belt 207 to rotate, and the filter screen belt 207 to be cleaned is continuously transferred to below the vibrating plate 307.
