The hopper moves from one end of the limit rod to the side close to the waste frame. When the crossbeam is separated from the threaded rod and the support rod drives the connecting rod to rotate back and forth, the connecting rod drives the throwing frame to rotate back and forth. When the throwing frame rotates upward near the end of the fan, the throwing frame is affected by gravity to drive the connecting rod to slide along the top of the support rod to the side close to the waste frame.

The present invention uses the coordination of the feed roller, the throwing frame, and the discharge port to enable the material to roll smoothly downward along the predetermined gap and finally be discharged accurately and efficiently through the discharge port. This not only ensures the smooth flow of the material, but also effectively avoids the risk of the material being mixed with foreign matter again during the transmission process, thereby significantly improving the purity of the material and the overall processing efficiency, ensuring the efficiency and accuracy of the production process. 5. The present invention realizes the function of accurately shortening the distance between the material and the fan during the material throwing process through the coordination of the adjustment mechanism, main rack, auxiliary rack and gear, etc., and can dynamically adjust the relative position of the material and the fan, so that the material is closer to the fan during the rising process, optimize the airflow effect, and thus enhance the material separation efficiency; 6. The present invention realizes the shaking function of the temporary storage basket through the coordination of the guide rod, temporary storage basket, groove and barrel, which can quickly discharge the material from the inside of the temporary storage basket and effectively prevent the material from accumulating inside the temporary storage basket or above the groove, thereby significantly improving the efficiency and smoothness of material processing.

When the main rack 502 moves toward the side close to the extension rod 501, the main rack 502 drives the gear 503 to rotate counterclockwise, and the gear 503 drives the auxiliary rack 504 to move toward one end of the throwing frame 417, and the auxiliary rack 504 drives the fan 3 to move toward the side close to the throwing frame 417, so that the distance between the fan 3 and the throwing frame 417 becomes smaller, and the debris and the mis-discharged material are separated for the second time.

[0028] Working principle: The motor of the fan 3 drives the fan blades to rotate to blow air, the output shaft of the motor 401 drives the transmission rod 402 to rotate, the transmission rod 402 drives the collar 412 to rotate, the rotating shaft 411 is limited by the flip plate 403, and the fixed rod 404 limits the flip plate 403, so that the transmission rod 402 drives the collar 412 to rotate around the axis of the rotating shaft 411, and the flip plate 403 rotates back and forth, the support rod 405 drives the support rod 405 to reciprocate, the support rod 405 drives the connecting rod 406 to reciprocate, and the connecting rod 406 drives the throwing frame 417 to reciprocate around the central axis of the flip plate 403, so that the materials and impurities inside the throwing frame 417 are thrown upward; At the same time, the motor 401 drives the transmission rod 402 to perform circular motion, and the transmission rod 402 drives the guide rod 415 to perform circular motion, and limits the transmission ball 413 through the sleeve 508, so that the guide rod 415 drives the transmission ball 413 to rotate inside the threaded rod 408. At the same time, the guide rod 415 drives the sleeve 508 to move back and forth through the transmission ball 413, and the sleeve 508 drives the connecting frame 506 to move back and forth, and the connecting frame 506 drives the main rack 502 to move back and forth, and the main rack 502 drives the gear 503 meshing with it to rotate around the axis of the positioning shaft 505, and the gear 503 drives the auxiliary rack 504 to move back and forth, so that the main rack 502 and the auxiliary rack 504 move in opposite directions, so that when the throwing frame 417 flips upward to throw up the mis-discharged materials and impurities, the fan 3 approaches the thrown-up materials and impurities, separates the impurities from the mis-discharged materials, and causes the mis-discharged materials to fall back into the temporary storage basket 9.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
