[0036] By setting the above structure, the driving motor 43 is turned on to drive the driving shaft 41 to rotate. When the driving shaft 41 rotates, the guide blades 42 in the driving box 4 are driven to rotate, thereby generating a guide effect in the driving box 4, so that the airflow in the inner cavity of the inclined lower end of the screening cylinder 31 enters 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 filtration and collection of floating particles generated during sorting in the screening cylinder 31, reducing dust pollution during sorting and improving the cleanliness of the environment in the sorting and processing area; and when the airflow 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, and at this time, the external airflow will continue to move along the port of the feed hopper 34 to the inclined lower end of the screening cylinder 31, so as to use the airflow to push the glass beads to roll down faster, thereby improving the sorting efficiency.

[0037] Reference Figure 1-Figure 4 , wherein the outer sleeve 3 and the screening cylinder 31 are both inclined, and the central axes of the outer sleeve 3 and the screening cylinder 31 coincide with each other, the inclined upper end of the screening cylinder 31 is rotatably connected with a feed hopper 34, 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 base plate 1; one end of the driving shaft 41 passes through the driving box 4 and is fixedly connected with a driving gear 46, and a driven gear ring 331 is fixedly connected to the limiting ring 33 at the inclined lower part, and the driving gear 46 is meshingly connected with the driven gear ring 331.

[0038] Through the arrangement of the above structure, when the driving shaft 41 rotates, the meshing action of the driving gear 46 and the driven gear ring 331 makes the outer sleeve 3 and the screening cylinder 31 rotate synchronously. At this time, the glass beads to be sorted are poured from the feed hopper 34 into the screening cylinder 31. At this time, as the inclined outer sleeve 3 and the screening cylinder 31 rotate, the glass beads will roll downward along the screening cylinder 31. In the process of rolling, the glass beads with smaller particle size will pass through the screening cylinder 31 and fall into the outer sleeve 3, thereby realizing rapid sorting. In addition, due to the rotation of the screening cylinder 31, the glass beads stuck in the screening holes of the screening cylinder 31 are rotated to the top of the screening cylinder 31, and will detach themselves under the action of gravity, thereby realizing anti-blocking effect and improving the sorting effect.

[0039] Reference Figure 1-Figure 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 connected to 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 and the screening cylinder 31 are parallel to each other, and a plurality of groups of air blowing holes 211 are arranged at equal intervals at the bottom of the air blowing pipe 21, and an air guide pipe 22 is fixed and connected to the side wall of the driving box 4, the other end of the air guide pipe 22 is connected to the inner cavity of the positioning ring 2, and the air guide pipe 22 and the guide pipe 441 are symmetrically arranged along the guide blade 42.

[0040] Through the arrangement of the above-mentioned structure, the filtered airflow will enter the drive box 4, and then enter the air blowing pipe 21 along the air guide pipe 22, and finally be blown toward the screening cylinder 31 from the air blowing hole 211, so as to continuously blow and clean the screening holes rotating to the top of the screening cylinder 31, and utilize the thrust of the airflow to remove the glass beads blocked in the screening holes of the screening cylinder 31, thereby further realizing the anti-blocking effect and improving the sorting effect of the screening cylinder 31.

[0041] Reference Figure 3 , Figure 6-Figure 8, wherein the vibration assembly includes a piston box 6, the piston box 6 is fixed on the top of the base plate 1, a knocking plate 61 is slidably connected in the piston box 6, a knocking spring 62 is fixedly connected between the bottom of the knocking plate 61 and the bottom of the piston box 6, the top of the knocking plate 61 is in contact with the outer wall of the inclined upper limit ring 33, and magnetic plates 63 are fixed on the outer wall of the inclined upper limit ring 33 at equal intervals, and the magnetic plates 63 and the knocking 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 filter cartridge 51, and a dust cleaning scraper 71 is rotatably connected to the linkage shaft 7 The dust scraper 71 fits against the inner wall of the dust filter cylinder 51, the bottom of the dust filter cylinder 51 is fixed and connected with a dust exhaust pipe 72, the other end of the dust exhaust pipe 72 extends through and extends to the outside of the sealing cylinder 5; the bottom of the sealing cylinder 5 is fixedly connected with a pneumatic box 73, the linkage shaft 7 extends into the pneumatic box 73 and is fixedly connected with a pneumatic impeller 74, the outer wall of the pneumatic box 73 is fixed with an air intake pipe 75 and connected, the other end of the air intake pipe 75 is connected to the inner cavity of the piston box 6, the outer wall of the piston box 6 is fixed with an air supply pipe 76 and both the air intake pipe 75 and the air supply pipe 76 are provided with a one-way valve.

[0042] It should be noted that the one-way valve in the air inlet pipe 75 can only allow the gas in the piston box 6 to enter the pneumatic box 73, while the one-way valve in the air supply pipe 76 can only allow the external air flow to enter the piston box 6; the dust exhaust pipe 72 can be opened periodically to discharge the powder trapped in the dust filter cylinder 51.

[0043] By setting the above structure, 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 to the side of the compressed knocking spring 62, so that the knocking spring 62 is compressed and stores energy, and at the same time, the gas in the piston box 6 is compressed, and the one-way valve in the air inlet pipe 75 is opened, so that this part of the compressed gas enters the pneumatic box 73 along the air inlet pipe 75, thereby pushing the air in the air flow. Under the action of force, 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 unblocking of the screening cylinder 31; and when the knocking plate 61 and the magnetic plate 63 are separated from the repulsive area, under the resetting action of the knocking spring 62, the knocking plate 61 will be quickly reset, and finally the knocking plate 61 will collide with the outer wall of the limit ring 33, so that the outer sleeve 3 produces a vibration effect, and it is transmitted to the screening cylinder 31, so as to utilize the vibration effect 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.

[0044] Reference Figure 1 , Figure 4An exhaust pipe 731 is fixed and connected to the outer wall of the pneumatic box 73 , the other end of the exhaust pipe 731 is connected to 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 can only allow the gas in the pneumatic box 73 to enter the positioning ring 2.

[0046] Through the arrangement of the above-mentioned structure, when the knocking plate 61 is reset and slides, 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 can be supplemented into the piston box 6, and then the airflow continuously enters the pneumatic box 73. 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 amount of air entering the blowing pipe 21, and increasing the airflow speed blowing to the screening drum 31, further improving the hole cleaning and anti-blocking effect, and ensuring the sorting effect of the screening drum 31.

[0047] Reference Figure 1-Figure 8 In the present invention, when in use, the driving motor 43 is turned on to drive the driving shaft 41 to rotate, and the meshing action of the driving gear 46 and the driven gear ring 331 is coordinated to make the outer sleeve 3 and the screening cylinder 31 rotate synchronously. At this time, the glass beads to be sorted are poured from the feed hopper 34 into the screening cylinder 31. At this time, as the inclined outer sleeve 3 and the screening cylinder 31 rotate, the glass beads will roll downward along the screening cylinder 31. In 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 realizing rapid sorting. In addition, due to the rotation of the screening cylinder 31, the glass beads stuck in the screening holes of the screening cylinder 31 are rotated to the top of the screening cylinder 31, and will automatically detach under the action of gravity, thereby realizing the anti-blocking effect and improving the sorting effect.

[0048] When the driving shaft 41 rotates, it will drive the guide blades 42 in the driving box 4 to rotate, thereby generating a guide effect in the driving box 4, so that the airflow in the inner cavity of the inclined lower end of the screening drum 31 enters the dust filter drum 51 along the dust extraction pipe 45, the dust extraction ring 44, the guide pipe 441 and the air guide arc plate 52, thereby filtering and collecting the floating particles generated during the sorting in the screening drum 31, reducing the dust pollution during the sorting, and improving the cleanliness of the environment in the sorting and processing area; then the filtered airflow will enter the driving box 4, and then enter the blowing pipe 21 along the air guide pipe 22, and finally be blown toward the screening drum 31 through the blowing hole 211, so as to continuously blow and clean the screening holes rotated to the top of the screening drum 31, so as to utilize the thrust of the airflow to remove the glass beads blocked in the screening holes of the screening drum 31, further realizing the anti-blocking effect and improving the sorting effect of the screening drum 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.
