The bottom of the first channel box 7 is connected to the second channel box 14, and the second channel box 14 is inclined to the lower right, and the bottom of the second channel box 14 is connected to the top left end of the feed box 11. A vibrator 15 is provided at the bottom of the feed box 11, and a second material discharge port 26 is provided at the right end of the bottom of the feed box 11. The second material discharge port 26 is located inside the discharge box 16, and the bottom of the discharge box 16 is a discharge inclined plate 18 extending downward. A through opening is opened on the right side wall of the discharge box 16, and a material blocking belt 17 is detachably installed at the through opening. A closed circulation mechanism is provided on the outside of the second channel box 14.

[0021] The blocking belt 17 is made of silicone skin. The scattered material is transported to the right through the vibration of the vibrator 15, and the material is more evenly distributed during the vibration. When the material finally falls from the second discharge port 26 onto the discharge inclined plate 18, the material is completely scattered at this time, but in different states. The material will be blocked by the blocking belt 17 in the process of sliding downward under its own gravity. The blocking belt 17 is made of silicone skin. The blocking belt 17 will not block the material from continuing to fall, but will only play a role in moving and smoothing the material, that is, the blocking belt 17 can change the material from an inclined or upright state to a state lying flat on the surface of the discharge inclined plate 18, so as to better facilitate the subsequent operation of the color sorter. It is worth mentioning that the blocking belt 17 is replaceable, so blocking belts 17 of different thicknesses can be selected according to the weight of the material to improve the applicability of the device.

[0022] The auxiliary breaking up assembly includes a rotating column 20 and a plurality of rotating plates 19. The rotating column 20 is arranged between the front and rear side walls in the first channel box 7 by rotating through a rotating shaft. The rotating column 20 is located below the material guiding inclined plate 12. The plurality of rotating plates 19 are evenly distributed on the outer surface of the rotating column 20 in the circumferential direction. The rotating plates 19 are hollowed out, and a balancing block 21 is provided inside the rotating column 20 away from the rotating shaft. When the material begins to enter the first channel box 7, the stacked material first hits the rotating plate 19, driving the rotating column 20 together with the plurality of rotating plates 19 to rotate, causing the rotating column 20 to lose balance. Under the action of the balancing block 21, the rotating column 20 has a tendency to restore balance, that is, it rotates in a certain direction and reverse direction, thereby performing the initial breaking up operation on the continuously falling material. The material that has passed through the auxiliary breaking up assembly has been initially broken up.

When the falling material collides with the tilted impact claw 23, it can be scattered again. The left outer wall of the second channel box 14 is provided with a variable frequency fan 8. The air outlet end of the variable frequency fan 8 is connected to the air supply duct 10. The end of the air supply duct 10 is provided with a main air outlet 25. The air supply duct 10 is fixedly connected to the left outer wall of the second channel box 14. The left inner wall of the second channel box 14 is provided with a plurality of air jet holes 24. The air jet holes 24 It is connected to the inside of the air supply duct 10; when in use, the variable frequency fan 8 is started, the variable frequency fan 8 outputs gas and is discharged from the main air outlet 25. The gas enters the second channel box 14 from the jet hole 24 during the process of passing through the air supply duct 10, which can impact the material and have the function of supporting the material, that is, further breaking up the material. At the same time, the variable frequency fan 8 can adjust the air volume, and the air volume on the air supply duct 10 can also be manually adjusted, thereby changing the size of the gas impact force to be suitable for materials of different weights, and has high applicability; in summary, the main breaking up component has a dual breaking up effect on the material, and has high flexibility of use and good effect.

[0024] The closed circulation mechanism includes an air storage box 13, an air pipe 9 and a plurality of vents 22. The air storage box 13 is provided on the right outer wall of the second channel box 14. The air storage box 13 is connected to the outside with an air pipe 9. The other end of the air pipe 9 is connected to the air inlet end of the variable frequency fan 8. The right inner wall of the second channel box 14 is provided with a plurality of vents 22. The vents 22 are connected to the inside of the air storage box 13. Specifically, when the variable frequency fan 8 is working, the air outlet end of the variable frequency fan 8 is connected to the inside of the second channel box 14 through the air delivery channel 10 and the jet hole 24. Air is delivered, and the air inlet end of the variable frequency fan 8 draws air from the inside of the second channel box 14 through the air pipe 9 and the air storage box 13, but most of the wind in the air delivery duct 10 is discharged from the main air outlet 25, so the amount of air delivered inside the second channel box 14 is less than the amount of air drawn. Therefore, when there is a lot of accumulation of logistics inside the first channel box 7, a negative pressure area will be generated in the area inside the second channel box 14 and away from the impact claw 23, and when the material passes through this area, it will be sucked into the negative pressure area, which will further improve the dispersion effect.

[0025] The impact claws 23 are divided into three groups and are evenly spaced from top to bottom along the left inner wall of the second channel box 14. There are multiple impact claws 23 in each group and they are evenly spaced from front to back along the left inner wall of the second channel box 14. The two adjacent groups of impact claws 23 are staggered with each other. This design allows the material to more fully contact and collide with the impact claws 23, thereby improving the breaking effect.

[0026] It should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
