The No. 1 mounting plate 308 is fixedly connected to the No. 1 slide bar 306 and the No. 2 slide bar 307. The No. 1 stepper motor 309 is fixedly connected to the No. 1 mounting plate 308. The No. 1 rotating rod 310 is fixedly connected to the output shaft of the No. 1 stepper motor 309 through the coupling 311. A through hole is provided on the No. 2 slide bar 307 at a position corresponding to the No. 1 rotating rod 310. One end of the No. 1 rotating rod 310 is connected to the No. 2 gear 312. Fixedly connected, the No. 1 stepper motor 309 is started, thereby rotating the No. 1 rotating rod 310, causing the No. 2 gear 312 at one end of the No. 1 rotating rod 310 to rotate, and the No. 2 gear 312 and the No. 1 gear 303 engage with each other for transmission, so that the No. 1 gear 303 drives the No. 2 connecting block 302 to rotate, the No. 2 connecting block 302 and the No. 1 connecting block 301 are fixedly connected to the screening hopper 1, and the No. 2 connecting block 302 and the No. 1 connecting block 301 are rotatably connected to the support rod 304, so that the screening hopper 1 can be easily rotated sideways, thereby dumping the internal material.
