Description

Technical Field

[0001] This utility model relates to the field of tubular chain conveyor technology, and in particular to an anti-clogging telescopic tubular chain conveyor. Background Technology

[0002] In the material handling fields of chemical, food, and building materials industries, tubular chain conveyors are widely used for the transfer of granular and powder materials due to their ability to achieve closed and efficient material transport. With the diversification of production scenarios, different working conditions place higher demands on the adaptability of conveying distance, the anti-clogging capability of equipment, and the ease of maintenance. Especially when it is necessary to flexibly adjust the conveying path or handle materials that are prone to residue, traditional tubular chain conveyors can no longer meet the needs of efficient and stable conveying.

[0003] Existing tubular chain conveyors have significant drawbacks: First, the conveying distance is inconvenient to adjust. Traditional devices are mostly designed with a fixed length, making it impossible to flexibly adjust according to actual needs. Changing the conveying distance requires replacing the entire device or complex modifications, and adjustments can easily lead to loose meshing between the chain and toothed rollers, resulting in unstable transmission and reduced material conveying efficiency. Second, they are prone to clogging and difficult to clean. Material easily remains on the inner wall of the pipe during conveying, and long-term accumulation can cause blockages. Most devices lack automatic cleaning mechanisms, and manual cleaning is not only time-consuming and labor-intensive but also affects production continuity. Third, maintenance costs are high. In some devices with cleaning functions, the cleaning components are mostly integrated designs, requiring complete disassembly and replacement after wear, which is cumbersome and increases maintenance costs. These problems restrict the adaptability and operational stability of tubular chain conveyors, making it difficult to meet diverse production needs. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figure 2-4 This utility model provides an embodiment of an anti-clogging telescopic tube chain conveyor, comprising a conversion box 1 and multiple conveyor discs 11. The adjacent sides of the multiple conveyor discs 11 are connected by chains 12. A changing toothed roller 9 is provided on the bottom side of the inner wall of the conversion box 1. A through hole is opened on the top side of the changing toothed roller 9, and a central column 14 is provided inside the through hole. A box cover 2 is rotatably connected to the top side of the conversion box 1. A first equal-diameter telescopic tube 3 is fixedly connected to the front end of the right side of the conversion box 1, and a second equal-diameter telescopic tube 4 is fixedly connected to the rear end of the right side of the conversion box 1. A transmission box 7 is fixedly connected to the right side of the first equal-diameter telescopic tube 3 and the second equal-diameter telescopic tube 4. A concave annular groove 23 is opened on the outer wall of the conveyor disc 11, and two scraper rings 22 are provided inside the concave annular groove 23. A machine box 8 is fixedly connected to the top side of the transmission box 7. A motor 17 is installed inside the machine box 8. The drive end of the motor 17 passes through the top side of the transmission box 7 and is fixedly connected to a connecting rod 18. The bottom side of the connecting rod 18 is fixedly connected to... A transmission toothed roller 19 is provided, with its bottom side rotatably connected to the bottom side of the inner wall of the transmission box 7. The outer wall of the central column 14 is rotatably connected to the inner wall of the through hole. A limit plate 10 is fixedly connected to the top side of the central column 14, and a screw 15 is fixedly connected to the bottom side of the central column 14. The screw 15 is threadedly connected to the bottom side of the inner wall of the conversion box 1. A feed box 5 is fixedly connected to the right end of the outer wall of the first equal-diameter telescopic tube 3. The right side of the feed box 5 is fixedly connected to the left side of the transmission box 7. The top right end of the shrink tube 3 and the top side of the feed box 5 are both provided with feed inlets 6. The bottom left end of the first equal diameter telescopic tube 3 is provided with a discharge outlet 16. The bottom right end of the inner wall of the conversion box 1 is rotatably connected with four limiting toothed rollers 13. The adjacent sides of two limiting toothed rollers 13 and the adjacent sides of the other two limiting toothed rollers 13 are engaged with the chain 12. The outer wall of the changing toothed roller 9 is engaged with multiple chains 12. The outer wall of the transmission toothed roller 19 is engaged with multiple chains 12.

[0018] Specifically, firstly, the motor 17 is started to drive the connecting rod 18, which in turn drives the transmission toothed roller 19 to rotate. Through the meshing of the transmission toothed roller 19 and the chain 12, the conveyor disc 11 and the chain 12 are driven to rotate synchronously. At the same time, the changing toothed roller 9 and the limiting toothed roller 13 rotate in linkage, so that the conveyor disc 11 and the chain 12 circulate within the first equal-diameter telescopic tube 3 and the second equal-diameter telescopic tube 4. After the material enters the first equal-diameter telescopic tube 3 from the inlet 6, it is driven by the conveyor disc 11 and the chain 12 to the outlet 16 for discharge. When it is necessary to extend the conveying distance, the limiting plate 10 is rotated to release the limiting of the changing toothed roller 9, and a smaller-sized changing toothed roller 9 is replaced to reduce the number of meshing conveyor discs 11 and chains 12, thereby adjusting the length of the telescopic tube and preventing the chain 12 from meshing too loosely with each toothed roller.

[0019] Reference Figure 1 , Figure 5 and Figure 6The two scraper rings 22 are located on the same side inside the concave ring groove 23. The right side of the scraper ring 22 is fixedly connected to a semi-threaded sleeve 24. The outer wall of the semi-threaded sleeve 24 at both ends is threaded with two semi-nuts 20. The top sides of the semi-nuts 20 at both ends are connected by a rotating shaft 21.

[0020] Specifically, during the conveying process, the scraper ring 22 cleans the residual material on the inner wall of the telescopic tube to prevent blockage; when the scraper ring 22 is worn, the half nut 20 is turned to open it, releasing the limit of the half threaded sleeve 24, and the scraper ring 22 can be replaced to ensure the cleaning effect and prevent blockage inside the tube.

[0021] Working Principle: In operation, the starting motor 17 first drives the connecting rod 18 to rotate the transmission toothed roller 19. Since the transmission toothed roller 19 meshes with multiple chains 12, its rotation simultaneously drives multiple conveyor discs 11 and chains 12. Simultaneously, because the multiple conveyor discs 11 and chains 12 mesh with the changing toothed roller 9 and multiple limiting toothed rollers 13, they also simultaneously drive the changing toothed roller 9 and multiple limiting toothed rollers 13 to rotate. This causes the multiple conveyor discs 11 and chains 12 to circulate within the first equal-diameter telescopic tube 3 and the second equal-diameter telescopic tube 4. The material to be conveyed is then placed into the first equal-diameter telescopic tube 3 through the inlet 6. During the movement of the conveyor discs 11 and chains 12, the material moves to the outlet 16 and falls. When the conveying distance needs to be extended, the limiting plate 10 can be rotated to release the limiting of the changing toothed roller 9, and then a smaller changing toothed roller can be installed. The roller 9 reduces the number of conveyor discs 11 and chains 12 meshing with the changing toothed roller 9, thereby extending the first equal-diameter telescopic tube 3 and the second equal-diameter telescopic tube 4. This also avoids the problem of loose meshing between multiple chains 12 and the changing toothed roller 9, the transmission toothed roller 19, and multiple limiting toothed rollers 13. Furthermore, the lengths of the first equal-diameter telescopic tube 3 and the second equal-diameter telescopic tube 4 can be automatically adjusted according to the distance of the transported material. During the movement of the chain 12, the scraper ring 22 cleans the material remaining on the inner wall of the first equal-diameter telescopic tube 3, preventing blockage. When the scraper ring 22 needs to be replaced, it can be opened and removed by rotating the two half-nuts 20, simultaneously releasing the limiting position on the two half-threaded sleeves 24. This allows for the replacement of the scraper ring 22, preventing wear and tear from prolonged use, which could lead to the inability to clean the material remaining inside the first equal-diameter telescopic tube 3 and cause blockage.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
