Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a flexible scraper-type chain tube conveyor. Background Technology

[0002] Chain tube conveyors are commonly used for conveying materials such as granules and powders. They use chains to drive scrapers to move within a closed conveying tube, achieving continuous material transport. They have advantages such as high conveying efficiency and environmental friendliness, and are widely used in industries such as chemical, food, and mining.

[0003] The existing chain tube conveyor has the following technical defects: 1. Inconvenient scraper replacement: Traditional scrapers are mostly integral structures and are fixedly connected to the conveyor chain. When replacing them, the conveyor pipe or the entire conveyor chain needs to be disassembled, which is cumbersome, time-consuming and labor-intensive, and seriously affects production efficiency; 2. Poor sealing and scraping effect: The scraper does not fit well with the inner wall of the conveyor pipe, which easily leads to material leakage or residue. Moreover, the scraper needs to be replaced as a whole after it is worn, resulting in high operating costs.

[0004] To address the aforementioned issues, there is an urgent need to design a flexible scraper-type chain tube conveyor that features convenient scraper replacement, good conveying flexibility, and excellent sealing performance. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flexible scraper-type chain tube conveyor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A flexible scraper-type chain tube conveyor includes a conveying pipe with an opening and a cover. Multiple plates are provided inside the conveying pipe, each plate has an annular groove, and each annular groove holds two rubber scrapers. Every two rubber scrapers form an annulus. One end and the other end of each plate are fixedly connected to an annulus, and each annulus is movably connected to a corresponding chain.

[0007] Preferably, a second threaded sleeve is fixedly connected to one end and the other end of the conveying pipe, and a bolt is threaded through each of the two second threaded sleeves. A curved plate is rotatably connected to each of the two bolts, and the two curved plates are in contact with the conveying pipe and the cover.

[0008] Preferably, one end of each of the plurality of ring bodies is threadedly connected to a first threaded sleeve, and one end of each of the plurality of first threaded sleeves is in contact with a corresponding plate body.

[0009] Preferably, the opening is fixedly connected with a rubber strip, and the rubber strip is in contact with the cover.

[0010] Preferably, one end of the opening and the other end are fixedly connected to multiple columns, and the multiple columns are movably connected through the cover.

[0011] Preferably, the cover is fixedly connected with a handle.

[0012] Preferably, the notch size of each of the multiple rings is larger than the corresponding size of the chain.

[0013] The beneficial effects of this utility model are as follows: 1. Through the coordination of the conveying pipe, opening, cover, plate, annular groove, and rubber scraper, when the chain and rings are engaged, the rings at both ends of the plate move with the chain. The annular groove holds the double semi-annular rubber scraper, and the opening of the conveying pipe is exposed inside. There is no need to disassemble the conveying pipe or the entire conveying chain; simply opening the cover at the opening allows direct disassembly and replacement of the rubber scraper that has moved to the opening position within the conveying pipe. This shortens maintenance time, reduces operational difficulty, and improves production continuity. Furthermore, the double semi-annular rubber scrapers can be spliced ​​to form a complete annular structure, tightly fitting the inner wall of the conveying pipe, enhancing sealing and scraping performance, reducing leakage and residue of granular and powdery materials, and ensuring conveying efficiency and environmental friendliness. Simultaneously, the semi-annular rubber scrapers can be disassembled and replaced individually without replacing the entire plate or scraper assembly, reducing material consumption and operating costs. The coordinated design of the chain and the rings at both ends of the plate gives the conveying chain good flexibility, adapting to different conveying paths. The overall structure is simple and reliable, making it particularly suitable for material conveying needs in industries such as chemical, grain, and mining, demonstrating outstanding practicality and promotional value. 2. Through the cooperation between the set conveying pipe, cover, second threaded sleeve, bolt and curved plate, the rotation and movement of the bolt at the corresponding second threaded sleeve drives the curved plate to move until the curved plate contacts the cover and restricts the cover at the opening, ensuring that the curved plate fits the cover and avoiding material leakage caused by the cover being loose due to gaps.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example 1, referring to Figures 1 to 5 A flexible scraper-type chain tube conveyor includes a conveying pipe 1 with an opening 2 that exposes the internal structure of the conveying pipe 1. A cover 3 is placed in the opening 2 to close the opening 2 and prevent material leakage. Multiple plates 4 are provided inside the conveying pipe 1, each of which is machined with an annular groove 5. Two rubber scrapers 6 are clamped in each annular groove 5, and each pair of rubber scrapers 6 forms an annulus to achieve material scraping on the inner wall of the conveying pipe 1 and sealing of the material conveyed by the plates 4. One end and the other end of each of the multiple plates 4 are fixedly connected to a ring 7, and the multiple rings 7 are movably connected to corresponding chains 9. Each ring 7 and the corresponding chain 9 form a relatively movable connection, providing flexible swing space for the conveying chain.

[0018] In this embodiment, a second threaded sleeve 10 is fixedly connected to one end and the other end of the conveying pipe 1. A bolt 11 is threaded through each of the two second threaded sleeves 10. The bolt 11 can move laterally in the corresponding second threaded sleeve 10 and can drive the curved plate 12 to move synchronously. The curved plate 12 is rotatably connected to each of the two bolts 11. Both curved plates 12 are in contact with the conveying pipe 1 and the cover 3. Driven by the bolts 11, both curved plates 12 can contact the outer wall of the conveying pipe 1 and the surface of the cover 3, thereby stably confining the cover 3 at the opening 2. A first threaded sleeve 8 is threaded to one end of each of the multiple rings 7. One end of each first threaded sleeve 8 is in contact with a corresponding plate 4. The first threaded sleeve 8 is used to cover the notch of the ring 7. To prevent chain 9 from slipping out, a rubber strip 14 is fixedly connected to the opening 2. The rubber strip 14 contacts the cover 3. When the cover 3 is closed at the opening 2, the rubber strip 14 will make tight contact with the inner surface of the cover 3, filling the small gap between the two and preventing material from leaking out of the gap. Multiple pillars 13 are fixedly connected to one end and the other end of the opening 2. Multiple pillars 13 are movable through the cover 3 and can form a movable through fit with the corresponding holes on the cover 3 to position the cover 3 and the opening 2. A handle 15 is fixedly connected to the cover 3 and is used to move the cover 3. The notch size of multiple rings 7 is larger than the corresponding size of the chain 9, which facilitates the separation of the chain 9 from the rings 7 for further disassembly.

[0019] The working principle of this embodiment is as follows: During normal operation, the chain 9, in conjunction with the rings 7 at both ends of the plate 4, drives multiple plates 4 to move within the conveying pipe 1. The double semi-circular rubber scrapers 6, fitted within the annular grooves 5 of the plate 4, are joined to form a complete ring and tightly adhere to the inner wall of the conveying pipe 1. This ensures both the conveying of granular and powdery materials and maintains a sealing scraping performance, reducing material leakage and residue. Furthermore, the combination of the chain 9 and the rings 7 provides the conveyor chain with good flexibility, adapting to different conveying paths. When the rubber scrapers 6 become worn and need replacement, there is no need to disassemble the conveying pipe 1 or the entire conveyor chain; only the conveyor needs to be opened. The cover 3 at the opening 2 of pipe 1 is used to move the plate 4 of the rubber scraper 6 to be replaced to the opening 2 position, and the double semi-circular rubber scraper 6 can be disassembled and replaced directly, which shortens the maintenance time, reduces the difficulty of operation, and quickly restores the equipment operation to ensure production continuity. After the rubber scraper 6 is replaced, the cover 3 is put on, and the rotation and movement of the bolt 11 at the corresponding second threaded sleeve 10 drives the curved plate 12 to move until the curved plate 12 is in close contact with the cover 3, restricting the cover 3 at the opening 2, avoiding material leakage caused by gaps in the cover 3 due to equipment operation vibration, and ensuring the continuous and stable conveying of the equipment.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
