The first sprocket 24 drives the chain 242 to drive the second sprocket 241 to rotate, thereby driving the first rotating roller 221 to rotate. Thus, the first rotating roller 221 and the second rotating roller 222 rotate simultaneously. The first rotating roller 221 and the second rotating roller 222 drive the corresponding feeding plate 223 to rotate, which is used to push the wheat seeds upward, so that the seeds are... The wheat seeds undergo multiple sliding screenings. After the wheat seeds are stirred and lifted, the wheat husks inside the seeds float up. Qualified wheat seeds fall through the mesh at the bottom of the inner screening box 21 onto the lower sieve plate 31. At the same time, the exhaust fan 282 draws in the wheat husks through the absorption hood 287, which then enter the impurity suction box 283 through the connecting pipe 28. Finally, the hydraulic rod 27 supports the baffle 25 to rise and slide through the discharge port 211 onto the guide plate 212, falling into the first receiving box 29. The vibration motor 32 vibrates the sieve plate 31, screening the wheat seeds again through the sieve plate 31. Finally, the wheat seeds fall into the second receiving box 33 and the third receiving box 34 respectively.

[0033] In summary, by setting up multi-stage screening components and a suction structure in the screening device, the wheat husks that float out during the first stage of screening are sucked into the suction box 283 by the exhaust fan 282, thus preventing the floating wheat husks from polluting the environment.
