[0018] like Figures 1 to 4As shown, this embodiment of the bauxite coarse and fine material classification and conveying switchable channel screening device includes a circular plate 1. The upper and lower surfaces of the circular plate 1 are respectively provided with an inlet 2 and an outlet 3, and two outlets 3 are symmetrically arranged on the lower surface of the circular plate 1. The inlet 2 is located in the middle of the upper surface of the circular plate 1. An outer shell 4 is provided inside the circular plate 1, and a partition 6 is connected to the middle of the inner part of the outer shell 4. The partition 6 is connected to the inner wall of the outer shell 4, dividing the internal space of the outer shell 4 into two equal parts. A classification conveying mechanism is provided on the outer surface of the outer shell 4. Through the classification conveying mechanism, the coarse and fine bauxite can be conveyed separately. A screening cylinder 9 is provided directly above the circular plate 1. The screening cylinder 9 screens the bauxite, separating it into coarse and fine materials. A connecting ring 10 is connected to the middle of the outer surface of the screening cylinder 9, and both the upper and lower surfaces of the screening cylinder 9 and the connecting ring 10 are reserved with... The screen 9 has an opening 11 through which bauxite can be added. A filter screen 12 is connected inside the screen 9, and a vibrating motor is connected to one end of the filter screen 12. After the bauxite enters the screen 9, it will fall onto the filter screen 12. At this time, by starting the vibrating motor, the bauxite can be fully screened. The model of the vibrating motor is selected according to actual needs. It is installed on the right end of the screen 9 and connected to the filter screen 12. An end cover is set on the left end surface of the screen 9. The vibrating motor can be inspected and replaced by removing the end cover. Support plates 13 are connected to both the left and right ends of the screen 9. A connecting plate 14 is connected to the rear end surface of the support plate 13, and a switching mechanism is set on the rear end surface of the connecting plate 14. Through the switching mechanism, the outer shell 4 can be rotated, thereby cooperating with the grading conveying mechanism to switch the conveying channel and realize the separate conveying of coarse and fine bauxite.

[0019] Specifically, a circular groove is provided on the front surface of the circular plate 1, and the outer shell 4 is located inside the circular groove, so that the outer shell 4 can be stored and installed inside the circular plate 1.

[0020] Furthermore, the grading and conveying mechanism includes a feed pipe 7 and a discharge pipe 8. The feed pipe 7 and the discharge pipe 8 are respectively set on the upper and lower surfaces of the outer shell 4, and there are two feed pipes 7 and two discharge pipes 8 symmetrically arranged about the left and right sides of the partition plate 6. The two feed pipes 7 are used to transport coarse and fine bauxite into two different spaces inside the outer shell 4, and finally discharge them through the two discharge pipes 8.

[0021] Furthermore, a door leaf 5 is connected to the front surface of the outer casing 4, and the connection between the door leaf 5 and the outer casing 4 is sealed. The interior of the outer casing 4 can be cleaned by opening the door leaf 5, and the sealing between the door leaf 5 and the outer casing 4 can be achieved using conventional technical means.

[0022] Furthermore, the switching mechanism includes a dual-axis servo motor 16, a turntable 17, a connecting block 18, a first transmission belt 19, a second transmission belt 20, and a rotating block 21. The dual-axis servo motor 16 is mounted at the middle of the rear end surface of the connecting plate 14, and the front end of the dual-axis servo motor 16 extends through the connecting plate 14 and the circular plate 1 to connect with the outer shell 4. The turntable 17 is provided on the left side of the dual-axis servo motor 16, and the rear ends of both the dual-axis servo motor 16 and the turntable 17 are connected to the connecting block 18. The outer surfaces of the two connecting blocks 18 are connected to the first transmission belt 19. The outer surface of the turntable 17 is connected to the second transmission belt 20, and the other end of the second transmission belt 20 is connected to the rotating block 21, which is then fitted and secured. The dual-axis servo motor 16 is selected according to actual needs and is fixed on the outer surface of the left end of the screening cylinder 9. By starting the dual-axis servo motor 16, it can simultaneously control the outer shell 4 and the connecting block 18 to rotate synchronously at the same speed. Under the drive of the first transmission belt 19, the turntable 17 will rotate, and then under the drive of the second transmission belt 20, the rotating block 21 will drive the screening cylinder 9 to rotate. During this process, it is important to note that a test should be performed in advance to ensure that the diameter ratio between the connecting block 18 and the rotating block 21 meets the requirements. This ensures that when the screening cylinder 9 rotates 90°, the feed pipe 7 can be aligned with the feed inlet 2. To facilitate the setting of the diameter ratio, the included angle between the feed pipe 7 and the partition plate 6 should be controlled to be an integer.

[0023] Furthermore, a fixing rod 15 is provided above the dual-axis servo motor 16. The bottom end of the fixing rod 15 is connected to the connecting plate 14, and the top end of the fixing rod 15 is connected to the connecting ring 10. The fixing rod 15 provides stable support for the screening cylinder 9.

[0024] Furthermore, the connecting ring 10 is circular, and the outer surface of the screening cylinder 9 is tightly fitted with the inner wall of the connecting ring 10. The lower surface of the connecting ring 10 is tightly fitted with the upper surface of the circular plate 1. This ensures that the bauxite inside will not spill out when the screening cylinder 9 rotates, and at the same time ensures that the bauxite can smoothly enter the interior of the outer shell 4 after rotating 90°.

[0025] The method of use in this embodiment is as follows: Bauxite is loaded into the screening cylinder 9, at which point one of the two feed pipes 7, the feed inlet 2, and the opening 11 are aligned. The bauxite is then screened on the filter screen 12. The fine material falls through the screen and finally enters one of the two independent spaces inside the outer shell 4. At this time, the discharge pipe 8 is aligned with one of the two discharge inlets 3, and the fine material is discharged from the inside of the outer shell 4. After all the fine material has been discharged, the outer shell 4 is rotated at a fixed angle by the switching mechanism, so that the other feed pipe 7 is aligned with the feed inlet 2 and the opening 11. At this time, the screening cylinder 9 rotates 90°, so that the coarse material is conveyed and discharged.

[0026] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
