At this time, the vibration motor 301 drives the coarse screen 302 and the fine screen 303 to vibrate through the shell 1, so that the coarse screen 302 and the fine screen 303 screen the grain raw materials twice to remove the particulate impurities therein. At the same time, in the process of the grain raw materials passing through the coarse screen 302 and falling to the surface of the fine screen 303, the suction fan 304 can be started to absorb dust and fine impurities in the grain raw materials, and then transport them to the inside of the dust storage box 306. When metal debris is mixed in the grain raw materials, the electromagnet 308 is energized, so that the electromagnet 308 generates magnetic absorption of the metal debris in the falling process. When the electromagnet 308 needs to be cleaned, the first motor 305 is started, so that the first motor 305 drives the support plate 307 to rotate, and the support plate 307 drives the electromagnet 308 to rotate, so that the electromagnet 308 is exposed on the surface of the shell 1, and then it is convenient to clean the metal debris on the surface of the electromagnet 308, so as to meet the needs of cleaning different types of grain raw materials.

[0022] Furthermore, the inclination angles of the coarse sieve 302 and the fine sieve 303 are opposite, and the aperture of the fine sieve 303 is smaller than that of the coarse sieve 302.

The second fixed frame 405 is connected to one side of the surface of the third motor 402, and the second limiting rod 406 runs through the interior of the second fixed frame 405. A fixed frame 403, a first limiting rod 404, a second fixed frame 405 and a second limiting rod 406 are arranged. When in use, the second motor 401 is first started. At this time, the second motor 401 drives the first fixed frame 403 to rotate along the first limiting rod 404, and the first fixed frame 403 drives the coarse screen 302 to rotate. Then the third motor 402 is started. At this time, the third motor 402 drives the second fixed frame 405 to rotate along the second limiting rod 406, and the second fixed frame 405 drives the fine screen 303 to rotate, thereby achieving the purpose of adjusting the angles of the coarse screen 302 and the fine screen 303, and then the optimal screening angle can be adjusted according to the characteristics of different grain raw materials.

[0025] Furthermore, the first fixed frame 403 is fixed on the surface of the coarse screen 302, and the second fixed frame 405 is fixed on the surface of the fine screen 303. Through the setting of the first fixed frame 403 and the second fixed frame 405, when in use, the first fixed frame 403 can provide support for the coarse screen 302, and the second fixed frame 405 can provide support for the fine screen 303.

[0026] Furthermore, the curvature of the first limiting rod 404 matches the rotation trajectory of the coarse screen 302, and the curvature of the second limiting rod 406 matches the rotation trajectory of the fine screen 303.

At this time, the vibration motor 301 drives the coarse screen 302 and the fine screen 303 to vibrate through the shell 1, so that the coarse screen 302 and the fine screen 303 screen the grain raw materials twice to remove the particulate impurities therein. At the same time, in the process of the grain raw materials passing through the coarse screen 302 and falling onto the surface of the fine screen 303, the suction fan 304 can be started to absorb dust and fine impurities in the grain raw materials, and then transport them to the inside of the dust storage box 306. When metal debris is mixed in the grain raw materials, the electromagnet 308 is energized, so that the electromagnet 308 generates magnetic absorption of the metal debris in the falling process. When the electromagnet 308 needs to be cleaned, the first motor 305 is started to The first motor 305 drives the support plate 307 to rotate, and the support plate 307 drives the electromagnet 308 to rotate, so that the electromagnet 308 is exposed on the surface of the shell 1, so as to facilitate the cleaning of metal debris on the surface of the electromagnet 308. When it is necessary to adjust the angles of the coarse screen 302 and the fine screen 303, the second motor 401 is first started. At this time, the second motor 401 drives the first fixed frame 403 to rotate along the first limiting rod 404, and the first fixed frame 403 drives the coarse screen 302 to rotate, and then the third motor 402 is started. At this time, the third motor 402 drives the second fixed frame 405 to rotate along the second limiting rod 406, and the second fixed frame 405 drives the fine screen 303 to rotate, thereby achieving the purpose of adjusting the angles of the coarse screen 302 and the fine screen 303.
