When the soybeans fall to the first screening plate 12, due to the inclined setting of the first screening plate 12, the soybeans will slowly roll on the first screening plate 12, and at the same time, the first screening plate 12 and the second screening plate 13 are driven to reciprocate horizontally through the squeezing reset component. After one screening is completed, the soybeans fall onto the second screening plate 13 to continue the secondary screening, which greatly improves the screening effect. After screening, the soybeans are discharged from the discharge hole 23.

The two ends of the rotating rod 19 are respectively rotatably mounted on the opposite inner walls of the transmission chamber. Two cams 20 are fixedly sleeved on the rotating rod 19. The two cams 20 are respectively adapted to the first screen plate 12 and the second screen plate 13. The rotating rod 19 is connected to one of the rotating shafts 5 through a transmission unit. The side portions of the first screen plate 12 and the second screen plate 13 are each provided with two guide grooves.

One ends of the four return springs 16 are respectively fixedly mounted on the sides of the first screening plate 12 and the second screening plate 13, and the other ends of the four return springs 16 are fixedly mounted on the side inner wall of the transmission chamber. The advantage of this arrangement is that through the arrangement of two cams 20 and multiple return springs 16, the extrusion and return functions of the first screening plate 12 and the second screening plate 13 can be realized, which is convenient for improving the screening effect.

[0031] like Figure 4 As shown, the transmission unit includes a worm 21 and a worm wheel 22. The worm 21 is fixedly arranged on one of the rotating shafts 5, and the worm wheel 22 is fixedly sleeved on the rotating rod 19. The worm 21 and the worm wheel 22 are meshed and installed. The advantage of such an arrangement is that through the arrangement of the worm 21 and the worm wheel 22, the function of synchronously rotating the rotating rod 19 can be realized through one of the rotating shafts 5.

[0034] When soybeans are put into the feed hopper, the gravity of the soybeans drives the two flip plates 3 to rotate synchronously, so that the soybeans fall into the screening box 1 for cleaning. Then, the two flip plates 3 realize the reset function under the action of multiple torsion springs 4 to prevent dust from escaping and polluting the air and causing harm to the user's body. During the cleaning process, the air pump 11 is started to discharge the internal dust. The filtering function of the filter plate 9 can prevent dust and foreign matter from being discharged from the exhaust pipe. When the filter plate 9 needs to be cleaned after long-term use, the pull ring 10 is pulled to drive the filter plate 9 to slide in the rectangular slide groove to realize the cleaning function. The operation is simple and convenient.

[0035] After being cleaned by two cleaning brushes 6, the soybeans first fall onto the first screening plate 12. Since the first screening plate 12 is tilted, the soybeans will slowly roll on the first screening plate 12. When the soybeans are rolling, through the meshing action of the worm 21 and the worm wheel 22, the rotating rod 19 will rotate synchronously with one of the rotating shafts 5, thereby driving the two cams 20 to rotate synchronously, repeatedly squeezing the first screening plate 12 and the second screening plate 13, and due to the setting of multiple reset springs 16, the first screening plate 12 and the second screening plate 13 can be driven to reset, so that the first screening plate 12 and the second screening plate 13 reciprocate horizontally. After one screening is completed, the soybeans fall onto the second screening plate 13 to continue the secondary screening, which greatly improves the screening effect. After screening, the soybeans are discharged from the discharge hole 23. During screening, they are collected through the first collecting box 17 and the second collecting box 18, which is convenient for subsequent cleaning by the staff.
