A tail passive drum 6 is fixedly connected to the outer wall of the first rotating column 5. An anti-tearing lifting belt 7 is provided on the outer wall of the tail passive drum 6. A hopper 8 is fixedly connected to the outer wall of the anti-tearing lifting belt 7. A U-shaped strip 11 is fixedly connected to the outer wall of the bucket elevator housing 1. A rectangular plate 9 is fixedly connected to the outer wall of the bearing seat 4. The outer wall of the rectangular plate 9 is slidably connected to the inner wall of the U-shaped strip 11. A first fixing frame 12 is fixedly connected to the outer wall of the bucket elevator housing 1. A screw rod 13 is threadedly connected to the inside of the first fixing frame 12. The lower end of the screw rod 13 is rotatably connected to the inside of the bearing seat 4. An adjustment groove 10 is provided on the outer wall of the bucket elevator housing 1. The outer wall of the first rotating column 5 is slidably connected to the inner wall of the adjustment groove 10. A power assembly is provided on the outer wall of the bucket elevator housing 1, and the power assembly is used for bucket elevator conveying of alumina powder; the power assembly includes a second fixing frame 15, the inner wall of the second fixing frame 15 is fixedly connected to the outer wall of the bucket elevator housing 1, a first motor 16 is fixedly connected to the upper surface of the second fixing frame 15, an output end of the first motor 16 is fixedly connected to a first rotating wheel 17, a belt 18 is provided on the outer wall of the first rotating wheel 17, a second rotating column 20 is rotatably connected to the inside of the bucket elevator housing 1, a second rotating wheel 19 is fixedly connected to the outer wall of the second rotating column 20, the inner wall of the belt 18 is in mutual fit with the outer wall of the second rotating wheel 19, and a head active drum 21 is fixedly connected to the outer wall of the second rotating column 20. The inner wall of the anti-tearing lifting belt 7 is in mutual fit with the outer wall of the head active drum 21;

[0026] Specifically, during use, start the first motor 16. The start of the first motor 16 drives the first rotating wheel 17 to rotate. The rotation of the first rotating wheel 17 drives the second rotating wheel 19 to rotate through the belt 18. When the second rotating wheel 19 rotates, it causes the second rotating column 20 to rotate. When the second rotating column 20 rotates, it drives the head active drum 21 to rotate. The rotation of the head active drum 21 drives the tail passive drum 6 to rotate through the anti-tearing lifting belt 7. At the same time, the anti-tearing lifting belt 7 drives the hopper 8 to continuously convey the alumina powder inside the feeding housing 2 from a low position to a high position and then discharge it from the discharge port 22. When it is necessary to adjust the distance between the tail passive drum 6 and the head active drum 21, rotate the screw rod 13 to cause the screw rod 13 to rotate inside the bearing seat 4 and at the same time drive the bearing seat 4 to move. When the bearing seat 4 moves, it drives the rectangular plate 9 to slide on the inner wall of the U-shaped strip 11. At the same time, the movement of the bearing seat 4 also causes the first rotating column 5 to slide on the inner wall of the adjustment groove 10, thereby realizing the adjustment of the distance between the tail passive drum 6 and the head active drum 21.

[0027] Refer to Figure 1 and Figure 4, a blanking port 22 is provided on the outer wall of the bucket elevator housing 1, a steel wire 23 is fixedly connected inside the anti-tear lifting belt 7, and a support base 14 is fixedly connected to the lower surface of the bucket elevator housing 1;

[0028] Specifically, by fixedly connecting the steel wire 23 inside the anti-tear lifting belt 7, the mechanical properties such as the strength and stiffness of the anti-tear lifting belt 7 are greatly improved, and the ability to withstand a greater breaking load is enhanced. The support base 14 is used to support the bucket elevator housing 1.

[0029] Refer to Figure 1 and Figure 5 , a disc 24 is fixedly connected to the outer wall of the bucket elevator housing 1, a fixing plate 25 is fixedly connected to the upper end of the disc 24, and a second motor 26 is fixedly connected to the outer wall of the fixing plate 25; a cylinder 27 is fixedly connected to the lower end of the disc 24, and a limiting groove 28 is provided on the inner wall of the cylinder 27; the output end of the second motor 26 is fixedly connected to a rotating cylinder 29, an annular ring 30 is fixedly connected to the outer wall of the rotating cylinder 29, and the outer wall of the annular ring 30 is rotatably connected to the inner wall of the limiting groove 28; the outer wall of the rotating cylinder 29 is rotatably connected to the inner wall of the cylinder 27, a sliding groove 31 is provided on the outer wall of the rotating cylinder 29, and a circular slider 32 is provided on the inner wall of the rotating cylinder 29; a protruding circular block 33 is fixedly connected to the outer wall of the circular slider 32, the outer wall of the protruding circular block 33 is slidably connected to the outer wall of the sliding groove 31, and a stirring push column 34 is fixedly connected to the lower end of the circular slider 32;

[0030] Specifically, when a large amount of alumina powder is blocked inside the feed shell 2, it will affect the normal operation of the process and the long-term operation of the equipment. At this time, by starting the second motor 26 to rotate, it can be promoted that when the circular slider 32 rotates and moves downward, it will drive the stirring push column 34 to rotate and move downward to disturb the alumina powder accumulated inside the feed shell 2, thereby preventing the alumina powder from accumulating inside the feed shell 2 and affecting the conveying.

[0031] Working principle: By increasing the length of the tail passive roller 6 and moving the bearing block 4 of the tail passive roller 6 outward, the bearing block 4 is kept away from the bearing block 4, reducing the problem of material leakage at the shaft seal of the tail passive roller 6 and increasing the service life of the system. By internally fixedly connecting the steel wires 23 of the anti-tear lifting belt 7, the mechanical properties such as the strength and stiffness of the anti-tear lifting belt 7 are greatly improved, enhancing the ability to withstand a greater breaking load, reducing the maintenance rate of the equipment, and at the same time meeting the requirements of the material characteristics and transportation of alumina powder, achieving the best effect of transporting alumina powder in an energy-saving manner. Start the second motor 26 to rotate. When the second motor 26 rotates, it will drive the ring 30 to rotate on the inner wall of the limit groove 28 through the rotating cylinder 29. At the same time, the rotating cylinder 29 will also rotate on the inner wall of the cylinder 27. When the rotating cylinder 29 rotates, it will cause the protruding round block 33 to slide on the inner wall of the sliding groove 31 and drive the round slider 32 to rotate on the inner wall of the rotating cylinder 29 while moving downward. When the round slider 32 rotates and moves downward, it will drive the stirring push column 34 to rotate and move downward to disturb the alumina powder accumulated inside the feeding shell 2, thus preventing the alumina powder from accumulating inside the feeding shell 2 and affecting the transportation.

[0032] 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. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
