When screening, first put the feed into the shell 1 and let it fall onto the screening plate 201. The impurities in the feed will fall through the screening holes 202, and the screened feed will flow out through the first discharging plate 209, and the screened impurities will flow out through the second discharging plate 210. When screening, the nut 207 can be loosened to allow the slider 204 to move in the chute 203, driving the adjusting plate 208 to move at one end of the screening plate 201. The adjusting plate 208 can block the screening hole 202, and the size of the screening hole 202 can be adjusted as needed, so that different feeds and different impurities can be screened, and the screening effect is very good.

When screening, the nut 207 can be loosened to allow the slider 204 to move in the slide 203, driving the adjustment plate 208 to move at one end of the screening plate 201. The adjustment plate 208 can block the screening hole 202, and the size of the screening hole 202 can be adjusted as needed, so that Different feeds and different impurities can be screened, and the screening effect is very good. When screening, start the motor 306, and the motor 306 drives the rotating rod 307 to rotate, and the eccentric hammer 308 at one end of the rotating rod 307 is driven to rotate together. The rotation of the eccentric hammer 308 makes the connecting plate 301 vibrate at one end of the spring 302, and the connecting plate 301 will drive the outer shell 1 to vibrate together, so that the feed in the outer shell 1 can be well screened. The setting of the spring 302 can limit the vibration amplitude of the connecting plate 301 to prevent the vibration amplitude of the connecting plate 301 and the outer shell 1 from being too large to cause the feed to be shaken out of the outer shell 1.
