[0045] The practical working principle of the present invention is as follows: when the material is screened and distributed, the motor 5 starts, driving the end shaft 40 in the bearing seat 3 to drive synchronously in the same direction, so that the screen cage 4 rotates synchronously in the same direction. The material is put into the cover shell 1 from the feed port. When passing through the feed hopper 10, the material collides with the material leveling roller 7, driving the material leveling roller 7 to rotate randomly. When rotating, the side wall of the material leveling roller 7 will guide the material in contact with it to the direction it is facing. After being guided by multiple groups of material leveling rollers 7, the material can fall evenly on the screen cage 4 under the feed hopper 10, thereby preventing the screen cage 4 from being damaged by concentrated impact. After that, the material moves with the rotation of the screen cage 4. In this process, the material with a particle size smaller than the gap between the adjacent fixed rods 42 and the rolling rollers 43 passes through the screen cage 4 and falls from between the two groups of bases 2, and the material with a particle size larger than the above gap is driven forward with the rotation of the screen cage 4. Finally, it is discharged from the bottom of the discharge cover 11; in this process, the lining plate 12 protects the inner wall of the cover shell 1 to prevent it from being worn by the material; when the screen cage 4 screens the material, the rolling joint 431 moves in the rolling hole 410, so that the rolling roller 43 can be displaced to a certain extent, so that the gap distance between the rolling roller 43 and the fixed rod 42 can change with the rotation of the screen cage 4, and can be affected by external forces, thereby preventing the material from being stuck on the screen cage 4; at the same time, after the material enters the screen cage 4, it will contact the distribution shaft 45 or the distribution rod 46, so that it is guided by it and the falling position is more uniform, so as to achieve the effect of uniform distribution; the connecting ring 44 is in the middle of the screen cage 4, and together with the end plate 41, it plays a structural reinforcement role, thereby extending the service life of the screen cage 4; after a long period of operation, the top cover 6 can be opened and the interior can be entered through the inspection port for inspection.
