Discharge ports are provided at the inclined lower ends of the outer sleeve 3 and the screening cylinder 31. It further includes: a dust suction component, which is arranged on the substrate 1 and is used to collect the fine particles floating up during the rolling sorting of glass beads; a vibration component, which is arranged on the substrate 1 and is used to apply a vibration effect to the outer sleeve 3.

[0035] Referring to Figures 4 - 8, wherein, the dust collection component includes a drive box 4, the drive box 4 is fixedly connected to the top of the substrate 1, a drive shaft 41 is rotatably connected inside the drive box 4, a guide vane 42 is fixedly connected to the outer wall of the drive shaft 41, a drive motor 43 is fixedly connected to the outer wall of the drive box 4, and the output end of the drive motor 43 is fixedly connected to the end of the drive shaft 41. A dust extraction ring 44 is rotatably connected to the inclined lower outer wall of the screening cylinder 31, and a dust extraction pipe 45 is rotatably connected to the center of the inclined lower end of the screening cylinder 31. The other end of the dust extraction pipe 45 is fixedly connected to the outer wall of the dust extraction ring 44, and both ends of the dust extraction pipe 45 are communicated with the screening cylinder 31 and the dust extraction ring 44 respectively. A guide pipe 441 is fixedly connected and communicated to the outer wall of the dust extraction ring 44, and the other end of the guide pipe 441 is communicated with the inner cavity of the drive box 4. A reinforcing rod is fixedly connected between the other side of the dust extraction ring 44 and the outer wall of the positioning ring 2, and a filtering part is arranged on the guide pipe 441; the filtering part includes a sealing cylinder 5, the sealing cylinder 5 is fixedly connected to the guide pipe 441, a dust filtering cylinder 51 is fixedly connected inside the sealing cylinder 5, a gas guiding arc plate 52 is fixedly connected to the inner wall of the sealing cylinder 5, the input end of the guide pipe 441 is communicated with the inner cavity of the gas guiding arc plate 52, the gas guiding arc plate 52 is communicated with the inner cavity of the dust filtering cylinder 51, the output end of the guide pipe 441 is communicated with the inner cavity of the sealing cylinder 5, and a dust cleaning part is arranged in the dust filtering cylinder 51.

[0036] With the above structure, when the drive motor 43 is turned on, it drives the drive shaft 41 to rotate. When the drive shaft 41 rotates, it drives the guide vane 42 inside the drive box 4 to rotate, thereby generating a guiding effect inside the drive box 4, so that the air flow in the inner cavity of the inclined lower end of the screening cylinder 31 enters the dust filtering cylinder 51 along the dust extraction pipe 45, the dust extraction ring 44, the guide pipe 441 and the gas guiding arc plate 52, so as to realize the filtration and collection of the floating particles generated during the sorting in the screening cylinder 31, reduce the dust pollution during sorting, and improve the cleanliness of the environment in the sorting processing area; and when the air flow in the inner cavity of the inclined lower end of the screening cylinder 31 is continuously sucked away, a negative pressure area will be formed in the inner cavity of the inclined lower end of the screening cylinder 31. At this time, the external air flow will continuously move along the port of the feed hopper 34 into the inclined lower end of the screening cylinder 31, so as to use the air flow effect to push the glass beads to roll down more quickly, thereby improving the sorting efficiency.

[0037] Refer to Figures 1 - 4 , wherein, both the outer sleeve 3 and the screening cylinder 31 are inclined, and the central axes of the outer sleeve 3 and the screening cylinder 31 coincide. A feed hopper 34 is rotatably connected to the inclined upper end of the screening cylinder 31, the feed hopper 34 is communicated with the inner cavity of the screening cylinder 31, and the feed hopper 34 is fixedly connected to the top of the substrate 1; one end of the drive shaft 41 penetrates through the drive box 4 and is fixedly connected with a drive gear 46, and a driven gear ring 331 is fixedly connected to the limiting ring 33 at the inclined lower part. The drive gear 46 is meshed with the driven gear ring 331.

[0038] With the above structure set, when the driving shaft 41 rotates, in cooperation with the meshing action of the driving gear 46 and the driven gear ring 331, the outer sleeve 3 rotates synchronously with the screening cylinder 31. At this time, the glass beads to be sorted are poured into the screening cylinder 31 from the feed hopper 34. At this time, along with the rotation of the obliquely arranged outer sleeve 3 and the screening cylinder 31, the glass beads will roll downward along the screening cylinder 31. During the rolling process, the glass beads with smaller particle sizes will pass through the screening cylinder 31 and fall into the outer sleeve 3, thus achieving rapid sorting. And due to the rotation of the screening cylinder 31, when the glass beads stuck in the screening holes of the screening cylinder 31 are rotated to the top of the screening cylinder 31, they will automatically fall off under the action of gravity, realizing the anti-blocking function and improving the sorting effect.

[0039] Refer to Figures 1 - 4 , wherein, an air blowing pipe 21 is fixedly connected to the inner wall of the positioning ring 2. The air blowing pipe 21 is communicated with the inner cavity of the positioning ring 2. The air blowing pipe 21 is located at the top of the clamping cavity between the outer sleeve 3 and the screening cylinder 31, and the air blowing pipe 21 is parallel to the screening cylinder 31. A plurality of groups of air blowing holes 211 are equidistantly arranged at the bottom of the air blowing pipe 21. A guide air pipe 22 is fixedly connected and communicated with the side wall of the driving box 4. The other end of the guide air pipe 22 is communicated with the inner cavity of the positioning ring 2, and the guide air pipe 22 and the diversion pipe 441 are symmetrically arranged along the diversion vane 42.

[0040] With the above structure set, the filtered air flow will enter the driving box 4, then enter the air blowing pipe 21 along the guide air pipe 22, and finally blow towards the screening cylinder 31 from the air blowing holes 211, so as to continuously blow and clean the screening holes rotated to the top of the screening cylinder 31. Thus, by using the thrust of the air flow, the glass beads blocked in the screening holes of the screening cylinder 31 are removed, further realizing the anti-blocking function and improving the sorting effect of the screening cylinder 31.

[0041] Refer to Figure 3 、 Figures 6 - 8, wherein, the vibration assembly includes a piston box 6, the piston box 6 is fixed to the top of the substrate 1, a striking plate 61 is slidably connected in the piston box 6, a striking spring 62 is fixedly connected between the bottom of the striking plate 61 and the bottom of the piston box 6, the top of the striking plate 61 is in contact with the outer wall of the limiting ring 33 on the upper inclined part, magnetic plates 63 are fixedly arranged at equal intervals on the outer wall of the limiting ring 33 on the upper inclined part, and the magnetic plates 63 and the striking plate 61 repel each other magnetically; the dust cleaning part includes a linkage shaft 7, the linkage shaft 7 is rotatably connected in the dust filtering cylinder 51, a dust cleaning scraper 71 is rotatably connected to the linkage shaft 7, the dust cleaning scraper 71 is in contact with the inner wall of the dust filtering cylinder 51, a dust discharging pipe 72 is fixedly connected and communicated at the bottom of the dust filtering cylinder 51, and the other end of the dust discharging pipe 72 penetrates and extends to the outside of the sealing cylinder 5; a pneumatic box 73 is fixedly connected to the bottom of the sealing cylinder 5, the linkage shaft 7 extends into the pneumatic box 73 and is fixedly connected with a pneumatic impeller 74, an air inlet pipe 75 is fixedly connected and communicated with the outer wall of the pneumatic box 73, the other end of the air inlet pipe 75 is communicated with the inner cavity of the piston box 6, an air supplement pipe 76 is fixedly connected and communicated with the outer wall of the piston box 6, and one-way valves are arranged in both the air inlet pipe 75 and the air supplement pipe 76.

[0042] It should be noted that the one-way valve in the air inlet pipe 75 only allows the gas in the piston box 6 to enter the pneumatic box 73, while the one-way valve in the air supplement pipe 76 only allows the external air flow to enter the piston box 6; the dust discharging pipe 72 can be opened regularly to discharge the powder and chips intercepted in the dust filtering cylinder 51.

[0043] Through the setting of the above structure, when the outer sleeve 3 rotates, the magnetic plates 63 evenly distributed on the limiting ring 33 will intermittently rotate above the striking plate 61. At this time, by using the repulsive force between the striking plate 61 and the magnetic plates 63, the striking plate 61 will slide towards the side that compresses the striking spring 62, so that the striking spring 62 is compressed and stores energy. At the same time, the gas in the piston box 6 will be compressed, and the one-way valve in the air inlet pipe 75 will be opened, so that this part of the compressed gas will enter the pneumatic box 73 along the air inlet pipe 75. Under the action of the air flow thrust, the pneumatic impeller 74 will be pushed to drive the linkage shaft 7 to rotate, so that the dust cleaning scraper 71 scrapes and cleans the inner wall of the dust filtering cylinder 51, improving the filtering effect of the dust filtering cylinder 51 and ensuring the smooth dredging of the screening cylinder 31; when the striking plate 61 and the magnetic plates 63 are out of the repulsive area, under the reset action of the striking spring 62, the striking plate 61 will quickly reset, and finally the striking plate 61 will collide with the outer wall of the limiting ring 33, so that the outer sleeve 3 generates a vibration effect and is transmitted to the screening cylinder 31. By using the vibration effect, the rolling speed of the glass beads is accelerated, the sorting efficiency is improved, and the blockage in the screening holes of the screening cylinder 31 is conveniently cleaned, further improving the sorting effect of the screening cylinder 31.

[0044] Refer to Figure 1 、 Figure 4, wherein, an exhaust pipe 731 is fixedly connected to the outer wall of the pneumatic box 73 and is in communication with the inner cavity of the positioning ring 2, and the other end of the exhaust pipe 731 is in communication with the inner cavity of the positioning ring 2, and a one-way valve is arranged in the exhaust pipe 731.

[0045] It should be noted that the one-way valve in the exhaust pipe 731 only allows the gas in the pneumatic box 73 to enter the positioning ring 2.

[0046] Through the setting of the above structure, when the knocking plate 61 slides back to its position, a suction force will be generated in the piston box 6, thereby opening the one-way valve in the air supply pipe 76, enabling the outside air flow to be supplemented into the piston box 6, and then enabling the air flow to continuously enter the pneumatic box 73. The gas continuously entering the pneumatic box 73 will push open the one-way valve in the exhaust pipe 731, causing this part of the air flow to enter the positioning ring 2 along the exhaust pipe 731, thereby increasing the air flow rate entering the blowing pipe 21, increasing the air flow speed blowing towards the screening cylinder 31, further improving the hole cleaning and anti-blocking effect, and ensuring the sorting effect of the screening cylinder 31.

[0047] Refer to Figures 1 - 8 , in the present invention, during use, the driving motor 43 is started to drive the driving shaft 41 to rotate. With the meshing action of the driving gear 46 and the driven gear ring 331, the outer sleeve 3 and the screening cylinder 31 rotate synchronously. At this time, the glass beads to be sorted are poured into the screening cylinder 31 from the feed hopper 34. At this time, along with the rotation of the obliquely arranged outer sleeve 3 and the screening cylinder 31, the glass beads will roll down along the screening cylinder 31. During the rolling process, the glass beads with smaller particle sizes will pass through the screening cylinder 31 and fall into the outer sleeve 3, thereby achieving rapid sorting. And due to the rotation of the screening cylinder 31, when the glass beads stuck in the screening holes of the screening cylinder 31 are rotated to the top of the screening cylinder 31, they will fall off automatically under the action of gravity, achieving the anti-blocking effect and improving the sorting effect.

[0048] When the driving shaft 41 rotates, it will drive the guide vane 42 in the driving box 4 to rotate, thereby generating a guiding effect in the driving box 4, enabling the air flow in the inner cavity at the lower inclined end of the screening cylinder 31 to enter the dust filter cylinder 51 along the dust extraction pipe 45, the dust extraction ring 44, the guide pipe 441 and the air guide arc plate 52, thereby realizing the filtering and collection of the floating particles generated during the sorting in the screening cylinder 31, reducing the dust pollution during sorting, and improving the cleanliness of the sorting processing area; then the filtered air flow will enter the driving box 4, and then enter the blowing pipe 21 along the guide pipe 22, and finally blow towards the screening cylinder 31 from the blowing holes 211, thereby continuously blowing air to clean the screening holes rotated to the top of the screening cylinder 31, thereby using the air flow thrust to remove the glass beads blocked in the screening holes of the screening cylinder 31, further realizing the anti-blocking effect and improving the sorting effect of the screening cylinder 31.

[0049] When the outer sleeve 3 rotates, the magnetic plates 63 evenly spaced on the limit ring 33 will intermittently rotate to the top of the knocking plate 61. At this time, the repulsive effect between the knocking plate 61 and the magnetic plate 63 will cause the knocking plate 61 to slide toward the side of the compressed knocking spring 62, so that the knocking spring 62 is compressed and stores energy. At the same time, the gas in the piston box 6 is compressed and the one-way valve in the intake pipe 75 is opened, so that this part of the compressed gas enters the pneumatic box 73 along the intake pipe 75. The pneumatic impeller 74 is pushed to rotate with the linkage shaft 7, so that the dust scraper 71 scrapes and cleans the inner wall of the dust filter cylinder 51, thereby improving the filtering effect of the dust filter cylinder 51 and ensuring smooth dredging of the screening cylinder 31; and when the knocking plate 61 and the magnetic plate 63 are separated from the repulsive area, the knocking plate 61 will be quickly reset under the reset action of the knocking spring 62, and finally the knocking plate 61 will collide with the outer wall of the limit ring 33, so that the outer sleeve 3 generates a vibration effect, which is transmitted to the screening cylinder 31. In this way, the vibration effect is utilized to accelerate the rolling speed of the glass beads, improve the sorting efficiency, and facilitate the cleaning of the blockages in the screening holes of the screening cylinder 31, further improving the sorting effect of the screening cylinder 31; and when the knocking plate 61 is reset and slid, a suction effect will be generated in the piston box 6, thereby opening the one-way valve in the air supply pipe 76, so that the external airflow is replenished into the piston box 6, and then the airflow continuously enters the pneumatic box 73, and the gas that continuously enters the pneumatic box 73 will push open the one-way valve in the exhaust pipe 731, so that this part of the airflow enters the positioning ring 2 along the exhaust pipe 731, thereby increasing the air flow entering the blowing pipe 21, and increasing the air flow speed blowing to the screening cylinder 31, further improving the hole cleaning and anti-blocking effect, and ensuring the sorting effect of the screening cylinder 31.
