[0002] With the continuous development of the times, metal products are becoming more and more common in people's lives. A large amount of waste will be generated in the process of production and processing of metal products. Some of these wastes are recyclable. Therefore, waste screening devices for the production and processing of metal products become very important.

[0003] In the related technology, the patent with application number CN202122503853.5 discloses a waste screening device for metal product production and processing, including a box body, a dispersing device, a screening device and a conveying device, the top wall of the box body is provided with a feed port and a through hole, the dispersing device is arranged on the box body, the screening device is arranged on the box body and below the dispersing device, and the conveying device is arranged on the box body and below the screening device. By continuously swinging the dispersing plate, the metal scrap falling from the feed port is dispersed and falls on the screen plate.
