A plurality of guide plates 24 are fixedly connected to the surface of the second rotating shaft 22. A connecting frame 20 is fixedly connected to the side of the material box 6. A second motor 21 is installed on the connecting frame 20. By operating the second motor 21, the second rotating shaft 22 can be driven to rotate, and then the guide plates 24 can be driven to rotate. By continuously changing the feeding direction of the plurality of guide plates 24, the feeding uniformity can be improved. The output shaft of the second motor 21 is fixedly connected to the shaft end of the second rotating shaft 22. The material box 6 and the guide plates 24 are located above the coarse division mesh plate 2.

[0029] Specifically, a second groove 26 is opened on the other side of the inner wall of the coarse division mesh plate 2. A slide bar 25 is fixedly connected inside the second groove 26. A slide sleeve 27 is slidably connected to the surface of the slide bar 25. The other end of the soft brush 10 is fixedly connected to the slide sleeve 27.

[0030] By adopting the above technical solution, with the sliding action of the slide sleeve 27 on the surface of the slide bar 25, the movement of the soft brush 10 can be made more stable.

At the same time, the second motor 21 is controlled by the controller 5 to work, driving the second rotating shaft 22 to rotate, so that the deflector 24 rotates. With the rotation of multiple deflectors 24 in turn for uniform material guiding, the raw materials are evenly guided onto the coarse division mesh plate 2. Then, the biaxial motor 19 is controlled by the controller 5 to work, driving the gear 17 to rotate.

At the same time, with the cooperation of the rotation of the coarse division mesh plate 2 in the damping bearing 28 driven by the third rotating shaft 29 and the elasticity of the torsion spring 31, the coarse division mesh plate 2 continuously vibrates up and down to screen the raw materials. The fine materials enter the fine division plate 1 through screening and are discharged through the fine material outlet 9. The coarse materials are located on the coarse division mesh plate 2 and are discharged through the coarse material outlet 8.

[0036] After screening for a period of time, the first motor 11 can be controlled by the controller 5 to work, driving the lead screw 13 to rotate, so that the threaded sleeve 12 drives the soft brush 10 to move, scraping the inner filter screen of the coarse division mesh plate 2 to prevent the filter holes from being blocked.
