[0045] The switching between scraper conveying and scraper sorting is automatically completed through mechanical linkage, without pausing the equipment, ensuring the continuous operation of the production line. Compared with the traditional method of stopping the machine to change tools, the working speed is improved. The elastic floating design of the flat scraper 402 can dynamically compensate for the wear gap between the scraper and the screen plate 3, avoiding hard friction and extending the life of the screen plate.

[0046] The present invention, by arranging the dispersion scrapers 403 on both sides of the scraper mounting frame 401 respectively, can enable the scraper assembly 4 to maintain the effect of pushing the material after moving from the upper feed channel 101 to the lower feed channel 101, thereby reducing the number of chains used and increasing the sorting efficiency. The longitudinal sliding of the synchronous connecting block 504 is controlled by the outer cylinder 512, so as to control the distance between the transmission chain and the screen plate 3. While preventing the transmission chain from falling, the distance between the scraper assembly 4 and the screen plate 3 is adjusted, thereby reducing the wear of the equipment and ensuring the conveying efficiency. Through the arrangement of the distance-adjusting guide rail 501 and the distance-adjusting roller 406, the relative position between the plane scraper 402 and the screen plate 3 can be controlled, thereby achieving the purpose of switching the conveying or screening function. Appropriate adjustments can be made according to the use requirements, thereby improving the application range of the equipment.
