The spiral blade 8 can quickly disperse the material conveyed by the spiral feeding mechanism 2, and the material that is relatively easy to pass through the screen in the screening box 3 is discharged from the screen as soon as possible from this stage to achieve screening. The spiral blade 8 pushes the material forward, and can also prevent the material from accumulating at the feeding part of the screen, protect the dangerous part of the screen, and improve the overall service life of the screen.

[0041] Furthermore, if Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, it also includes a cleaning ball interface 9, which is provided on both the material box 1 and the screening box 3.

Through the cooperation of the screening guide rod 17 and the screening guide rail 16, the screening drive mechanism 6 and the screening shaft 4 can be moved away from the screening box 3, so that the screening shaft 4 can be pulled out from the screening box 3. Through the cooperation of the feeding guide rod 19 and the feeding guide rail 18, the feeding drive mechanism 5 and the spiral feeding mechanism 2 can be moved away from the risk of the material box 1, so that the spiral feeding mechanism 2 can be pulled out from the material box 1, which is convenient for the disassembly of the spiral feeding mechanism 2 and the screening shaft 4.
