[0032] Specifically, the inner wall of the casing 3 is symmetrically provided with limiting grooves 301, and sliders are integrally formed at both ends of the limiting plate 11. The sliders of the limiting plate 11 are slidably inserted into the limiting grooves 301. The limiting plate 11 is arranged in parallel to the outer side of the screen 5, and a material guiding gap is arranged between the limiting plate 11 and the screen 5. The traction frame 12 is arranged in parallel to the inner wall of the casing 3, and a traction hole is opened on the surface of the traction frame 12.

The material guiding gap set between the limiting plate 11 and the screen 5 is larger than the circulation distance of the crops. Then, the limiting plate 11 and the sound-absorbing pad 13 limit the flying distance of dust and isolate the noise of the materials inside the casing 3, thereby facilitating the gathering of dust and improving the dust prevention effect.
