The output end of the second stepper motor 40 is connected to the bottom of the rotating rod 39. The second stepper motor 40 can drive the rotating rod 39 to rotate, and the rotation of the rotating rod 39 can drive the protruding column 38 to rotate around the output end of the second stepper motor 40 through the rotating shaft. During the rotation, the protruding column 38 will drive the swing rod 31 to swing around the central axis 35 through the sleeve 37, thereby realizing the driving effect.

[0023] Two external material receiving frames 28 are symmetrically installed on the surface of the convex outer frame 1, and the external material receiving frames 28 are located below the first discharge port 41.

Since the cam surface corresponds to the bottom end of the guide rod 9, under the action of the cam and the tension spring 10, when the cam rotates, the guide rod 9 can make the first unloading plate 8 move up and down, thereby realizing the first filtration of the material.

During the swinging process, the material inside the discharge bin 11 will fall into the second discharge plate 17, and the material smaller than the mesh of the second filter screen 19 will be filtered into the third discharge plate 20. At the same time, the inertia generated by the swinging will cause the material to move on the inclined bottom surface, so that the material will move to both sides of the second discharge plate 17 and the third discharge plate 20, and finally be discharged from the second discharge port 18 and the third discharge port 21. The discharged material will fall into the two internal receiving frames 29 respectively, thereby realizing the collection operation of medium-grained material and fine-grained material.
