Description

Technical Field

[0001] This utility model relates to the field of scraper conveyor technology, and in particular to a scraper conveyor suitable for conveying at large angles. Background Technology

[0002] With the development of modern industry, the demand for material transportation is increasing, especially in industries such as mining, coal, and power, which place higher demands on the efficiency and reliability of material conveying. Scraper conveyors, due to their simple structure, reliable operation, and strong conveying capacity, have become key equipment for material conveying in many industries. However, with the diversification of material conveying needs and the complexity of working environments, especially in steep-angle conveying, traditional scraper conveyors face many challenges. To adapt to the special requirements of steep-angle conveying and improve the stability and ease of maintenance of the equipment, the development of scraper conveyors suitable for steep-angle conveying is particularly important. This device not only maintains stable material conveying at large angles but also has significant advantages in the maintenance and replacement of vulnerable parts, improving working efficiency and service life.

[0003] Currently, traditional scraper conveyors mostly use chains or wire ropes as traction components. The chain drives the scrapers to move back and forth on the track to transport materials. The core components of the equipment include the drive unit, scrapers, track, and chain. Through the cooperation of these components, horizontal or inclined material conveying is achieved. The scrapers are connected to the chain by connecting pins or bolts. The contact surface of the scrapers is usually designed to contact the material, effectively scraping away the material and propelling it forward along the conveying path. Existing scraper conveyors can meet conventional conveying needs to a certain extent, but their stability and maintainability still face significant challenges for operation at large angles, over long distances, and in harsh environments.

[0004] The disassembly and replacement of damaged scrapers on existing scraper conveyors often requires complex operations, which are inconvenient and disrupt normal equipment operation, resulting in prolonged downtime. This is especially true for applications requiring frequent scraper replacements, where operators often need to spend significant time and effort on maintenance, impacting production efficiency. Therefore, improving the ease of scraper replacement and reducing downtime has become an urgent problem to be solved. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a scraper conveyor suitable for conveying at large angles, aiming to improve the problem of inconvenience in maintaining and disassembling damaged scrapers in scraper conveyors.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a scraper conveyor suitable for conveying at large angles, comprising a conveyor, wherein a connecting plate is provided inside the conveyor, and a disassembly assembly is provided inside the connecting plate;

[0007] The disassembly and assembly assembly includes a scraper, the bottom of which is fixedly connected to the top of a connecting plate. A clamping plate is fixedly connected to the bottom of the connecting plate. A connecting pin is slidably connected between the connecting plate, the scraper, and the clamping plate. A bolt is threaded inside the connecting pin. A knob is fixedly connected to one end of the bolt, and a conical column is fixedly connected to the other end of the bolt. A steel ball is provided inside the connecting pin. The steel ball is fitted into the clamping plate, and the conical column is in contact with the outer wall of the steel ball.

[0008] As a further description of the above technical solution:

[0009] The scraper has a limiting groove inside, and a support plate is slidably connected inside the scraper.

[0010] As a further description of the above technical solution:

[0011] A silicone plate is fixedly connected to the top of the support plate, and the top of the silicone plate is in contact with the inner wall of the conveyor.

[0012] As a further description of the above technical solution:

[0013] A limiting plate is fixedly connected to the bottom of the support plate, and the limiting plate is slidably connected inside the limiting groove.

[0014] As a further description of the above technical solution:

[0015] A telescopic rod is provided inside the limiting groove, and a spring is sleeved on the outer wall of the telescopic rod.

[0016] As a further description of the above technical solution:

[0017] One end of the telescopic rod and one end of the spring are fixedly connected to the bottom of the limiting plate, and the other end of the telescopic rod and the spring are fixedly connected inside the limiting groove.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, the clamping plate is first placed at the bottom of the connecting plate, and the connecting pin is inserted into the scraper, the connecting plate and the clamping plate. Then, the bolt is rotated by the knob so that the bolt extends into the connecting pin. Subsequently, the bolt is attached to the outer wall of the steel ball through the conical surface of the outer wall of the conical column, which achieves the effect of facilitating the installation of the scraper. This solves the problem of the inconvenience of maintaining and disassembling the damaged scraper of the scraper conveyor and improves the convenience of the scraper conveyor.

[0020] In this invention, the silicone plate is slidably limited in the limiting groove by the support plate and the limiting plate, and is supported by the tension of the spring, so that the silicone plate can always adhere to the inner wall of the conveyor. This achieves the effect that the scraper can always adhere to the shell, solving the problem that there is a certain gap between the scraper and the shell, which makes it easy to leak material, and that the scraper cannot always adhere to the shell after aging. This improves the practicality of the scraper conveyor. Attached Figure Description

The connecting pin 5 is internally threaded with a bolt 6, which secures the connecting pin 5 and ensures reliability and safety during assembly and disassembly. A knob 9 is fixedly connected to one end of the bolt 6, allowing operators to easily adjust the bolt 6 for quick assembly and disassembly, reducing maintenance time and labor intensity. A conical column 7 is fixedly connected to the other end of the bolt 6, providing a secure positioning function through its engagement with the connecting pin 5 and preventing loosening. A steel ball 8 is installed inside the connecting pin 5, providing a sliding fit between the connecting pin 5 and the clamping plate 4, ensuring smoother installation and disassembly of the connecting pin 5 and preventing jamming. The steel ball 8 also engages with the clamping plate 4, enhancing stability during disassembly. The conical column 7 fits snugly against the outer wall of the steel ball 8, and its shape design allows for precise contact with the steel ball 8, improving the accuracy of assembly and disassembly, making the installation and disassembly of the scraper 3 more convenient and faster.

[0030] Reference Figure 4The scraper 3 has a limiting groove 10 inside. The limiting groove 10 provides a guide track for the support plate 12, ensuring that the support plate 12 can slide smoothly within the scraper 3, while preventing the support plate 12 from shifting and maintaining a precise fit between the scraper 3 and the support plate 12. The support plate 12 is slidably connected inside the scraper 3, and the support plate 12 supports the silicone plate 11, allowing the silicone plate 11 to maintain a stable position, thereby improving the overall working efficiency and stability of the scraper 3. The silicone plate 11 is fixedly connected to the top of the support plate 12. The silicone plate 11, by adhering to the inner wall of the conveyor 1, ensures that it is always in close contact with the inner wall of the conveyor 1 during operation, achieving a good sealing and leak-proof effect, preventing material leakage or contamination. The bottom of the support plate 12 is fixedly connected to a limiting plate 13. The limiting plate 13 ensures that the support plate 12 does not exceed the specified range when sliding within the limiting groove 10, providing stability during the sliding process. The limiting plate 13 slides... Connected inside the limiting groove 10, the design of the limiting groove 10 allows the limiting plate 13 to slide smoothly, reducing friction and wear during operation. A telescopic rod 14 is installed inside the limiting groove 10, whose length can be adjusted according to work requirements, providing height adjustment functionality to ensure the scraper 3 can operate normally under different working conditions. A spring 15 is fitted on the outer wall of the telescopic rod 14, providing support through its elasticity, allowing it to return to its original state when subjected to external force, thus preventing deformation or damage during long-term use. One end of both the telescopic rod 14 and the spring 15 is fixedly connected to the bottom of the limiting plate 13, ensuring the telescopic rod 14 remains stable during operation. The other end of both the telescopic rod 14 and the spring 15 is fixedly connected inside the limiting groove 10, enhancing the support and stability of the telescopic rod 14, ensuring it maintains good working condition during use.

[0031] Working principle: When using this scraper conveyor suitable for large angle conveying, firstly, when installing the scraper 3, place the bottom of the scraper 3 on the top of the connecting plate 2, then place the clamping plate 4 at the bottom of the connecting plate 2, insert the connecting pin 5 into the scraper 3, connecting plate 2 and clamping plate 4, then rotate the bolt 6 by the knob 9, so that the bolt 6 extends into the connecting pin 5, then the conical surface of the bolt 6 through the outer wall of the conical column 7 fits against the outer wall of the steel ball 8, driving the steel ball 8 to extend out of the connecting pin 5, so that the steel ball 8 is fitted into the bottom of the clamping plate 4 for locking, thus achieving the effect of facilitating the installation of the scraper 3;

[0032] In use, the chain drives the scraper 3 and the top silicone plate 11 to rotate through the connecting plate 2, so that the silicone plate 11 adheres to the inner wall of the conveyor 1. The silicone plate 11 slides and is limited in the limiting groove 10 through the support plate 12 and the limiting plate 13, and is supported by the tension of the spring 15, so that the silicone plate 11 can always adhere to the inner wall of the conveyor 1. The spring 15 is limited in the limiting groove 10 through the telescopic rod 14, so that the scraper 3 can always adhere to the shell.

[0033] 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.
