[0030] Refer to Figure 1 and Figure 5, the bottom of the fixing plate 1 is fixedly connected with an arc-shaped funnel 21, the outside of the arc-shaped funnel 21 is fixedly connected with a collection box 22, the right side of the collection box 22 is fixedly connected with a power assembly, the power assembly includes a housing two 23, the left side of the housing two 23 is fixedly connected to the right side of the collection box 22, a cylinder 24 is installed inside the housing two 23, the driving end of the cylinder 24 is fixedly connected with a push rod 25. Here, it is designed that the cylinder 24 can drive the push rod 25 to displace. The left side of the power assembly is fixedly connected with a slide plate 26, the bottom of the slide plate 26 is fixedly connected with a triangular scraper 27, so that the slide plate 26 can be displaced, and then the alumina powder can be collected and summarized by the triangular scraper 27. The left side of the slide plate 26 is fixedly connected with a plurality of push rods 28. Here, it is designed that the rotating plate 29 can be rotated by the push rods 28. The left side of the collection box 22 is rotatably connected with a rotating plate 29, the left side of the collection box 22 is fixedly connected with a square plate two 30, the left side of the rotating plate 29 is fixedly connected with a plurality of sliding rods 31, and a second spring 32 is sleeved outside each of the plurality of sliding rods 31. Here, it is designed that the second spring 32 can be compressed and rebound to make the rotating plate 29 rotate and reset. The top of each of the plurality of sliding rods 31 is fixedly connected with a second limiting plate 33. The left side of the top of the tank body 2 is fixedly connected with an air flow machine 34, and the right side of the top of the tank body 2 is fixedly connected with a feed pipe 35. Here, it is designed that the large-particle alumina can fall into the inside of the tank body 2 through the feed pipe 35. The four corners of the bottom of the fixing plate 1 are fixedly connected with columns 36.

[0031] Refer to Figure 3-5 , the outside of the driving shaft 5 is rotatably connected inside the tank body 2, the top of the arc-shaped frame 7 is in contact with the bottom of the arc-shaped block 14. Here, it is designed that the contact between the arc-shaped frame 7 and the arc-shaped block 14 can cause the height of the arc-shaped block 14 to change. The outside of the first limiting plate 13 is slidably connected inside the sleeve 10. The bottom of the sliding column 12 is fixedly connected to the top of the arc-shaped block 14. One end of the first spring 11 is fixedly connected to the top side inside the sleeve 10, and the other end of the first spring 11 is fixedly connected to the top of the first limiting plate 13. Here, it is designed that the filter plate 17 can be impacted by the compression and rebound of the first spring 11, so that the filtration can be more sufficient. The bottom of the triangular scraper 27 is slidably connected inside the collection box 22, and the left side of the push rod 28 is in contact with the right side of the rotating plate 29. Here, it is designed that the rotating plate 29 is pushed up by the push rod 28 to make it rotate.

[0032] Working principle: First, large-particle alumina can be poured into the interior of the tank body 2 from the interior of the feed pipe 35. Then, the air flow machine 34 can be started. At this time, the large-particle alumina can be crushed by means of the air flow machine 34. Then, the motor 4 can be started. The rotation of the output end of the motor 4 drives the drive shaft 5 to rotate, thereby enabling the fixed disk 6 to rotate, and then enabling the arc-shaped frame 7 to perform a circular motion. At this time, with the movement of the arc-shaped frame 7, the arc-shaped block 14 can be lifted by means of the arc-shaped design at the top of the arc-shaped frame 7. At this time, the sliding column 12 can move upward, thereby enabling the limiting plate 13 to compress the first spring 11 and causing the first spring 11 to be compressed. Then, the arc-shaped block 14 can slide outside the fixed rod 8. When the top of the arc-shaped frame 7 passes across the bottom of the arc-shaped block 14, the arc-shaped block 14 will move downward. At this time, the arc-shaped block 14 can be reset by means of the compression and rebound of the first spring 11. Then, by means of the elastic force of the first spring 11, the striking plate 15 can be made to impact on the top of the filter plate 17, thereby enabling the filter plate 17 to vibrate. At this time, the alumina powder can be fully filtered, and the filtered powder will fall onto the surface of the chassis 19. With the rotation of the drive shaft 5, the arc-shaped scraper 18 will rotate, thereby scraping the powder into the interior of the arc-shaped groove 20 and then falling into the interior of the arc-shaped funnel 21 and the collection box 22. When it is necessary to collect the alumina powder, only the cylinder 24 needs to be started. The displacement of the push rod 25 is driven by the cylinder 24, thereby enabling the sliding plate 26 to move. Then, the powder inside the collection box 22 can be pushed to the outside by the triangular scraper 27. At this time, the push rod 28 will first contact the rotating plate 29 and cause the rotating plate 29 to rotate. Then, the sliding rod 31 can slide inside the second square plate 30. At this time, the second spring 32 can be compressed, and then a container can be used to collect the alumina powder. Then, when the push rod 28 retracts to the right side inside the collection box 22, the rotating plate 29 will be reset by means of the elastic force of the second spring 32.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
