Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, and in particular to scraper conveyors. Background Technology

[0002] Scraper conveyors are widely used in the industrial field, especially in industries such as coal mining, metallurgy, and chemicals. They play a crucial role in material transportation. In coal mining, they are responsible for transporting coal mined by the coal mining machine from the underground working face to the surface, ensuring the continuity of coal production. In the metallurgical industry, they are used to transport materials such as ore and slag, ensuring the smooth operation of the production line. Their efficient and stable operation plays a decisive role in the efficiency and effectiveness of the entire industrial production process, making them an indispensable and important piece of equipment for industrial material handling.

[0003] The existing scraper conveyor mechanical structure mainly consists of three parts: the head, the body, and the tail. The head is equipped with a drive motor, a reducer, and sprockets. The electrical energy output by the motor is converted into appropriate speed and torque by the reducer, driving the sprockets to rotate. The body is composed of a series of chutes connected together. The chutes are the material carrying channels. The scrapers are connected to the chain to form a scraper chain. Driven by the sprockets, the scraper chain circulates along the chutes, thereby realizing the material conveying. The tail serves to reverse the direction of the scraper chain, enabling the scraper chain to continuously circulate.

[0004] However, in actual production, it is difficult to achieve a completely uniform distribution of materials on the conveyor belt. For example, when mining coal underground, the coal pieces vary in size, and the thickness and position of their accumulation on the conveyor belt are highly random. This results in uneven stress on the conveyor belt, causing uneven deformation. At the same time, the vibration of the scraper conveyor itself during long-term operation exacerbates this height change of the conveyor belt. Traditional scraper structures are usually fixed in shape and cannot be adjusted according to these dynamic height changes of the conveyor belt. This causes the scraper and the conveyor belt to not fit tightly, seriously affecting the scraping effect, reducing the stability of equipment operation, frequently causing failures, and greatly restricting the improvement of production efficiency. Therefore, the scraper conveyor is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a scraper conveyor, which aims to improve the problems of poor adhesion between the scraper and the conveyor belt and inability to adapt to changes in height in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A scraper conveyor includes a conveyor with a feed inlet at the top, a motor fixedly connected to the outer wall of the conveyor, a conveyor chain fixedly connected to the output end of the motor, a scraper at the top of the conveyor chain, and a telescopic component at the bottom of the scraper.

[0008] The telescopic assembly includes a telescopic plate and a spring. The top of the telescopic plate is fixedly connected to the bottom of the scraper. A connecting plate is provided on the outer wall of the conveyor chain. A disassembly assembly is provided on the top of the connecting plate. A limit plate is fixedly connected to the bottom of the telescopic plate. The outer wall of the limit plate is slidably connected to the inside of the connecting plate. A fixing post is fixedly connected to the inner wall of the connecting plate. The outer wall of the fixing post is slidably connected to the inside of the telescopic plate. A spring is provided inside the connecting plate. The top of the spring is fixedly connected to the bottom of the limit plate. The bottom of the spring is fixedly connected to the inner wall of the connecting plate.

[0009] As a further description of the above technical solution:

[0010] The disassembly and assembly assembly includes a locking post, which is disposed at the bottom of the connecting plate.

[0011] As a further description of the above technical solution:

[0012] A fixing plate is fixedly connected to the outer wall of the transport chain, and a clamping plate is provided at the bottom of the fixing plate.

[0013] As a further description of the above technical solution:

[0014] The fixing plate has a sliding groove inside, the clamping plate has a sliding groove inside, and the clamping plate has a locking groove inside.

[0015] As a further description of the above technical solution:

[0016] A hollow column is fixedly connected to the top of the connecting plate, and a connecting column is slidably connected inside the hollow column.

[0017] As a further description of the above technical solution:

The top of the second spring is fixedly connected to the outer wall of the limiting ring, and the bottom of the second spring is fixedly connected to the inside of the hollow column.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the scraper can be set as a telescopic plate with an internal spring. When the scraper is running, the elastic force of the spring pushes the telescopic plate, so that the scraper is always in close contact with the conveyor belt. It can flexibly adapt to the height changes of the conveyor belt caused by uneven material distribution and equipment vibration, and solves the problems of poor contact between the scraper and the conveyor belt and inability to adapt to height changes, which significantly improves the scraping effect and the stability of equipment operation.

[0025] In this invention, the locking pin rotates by rotating a knob. When the knob is moved, the connecting pin and the sliding pin are driven by the knob and cooperate with the second spring to slide the locking pin inside the slot, thereby facilitating the disassembly and assembly of the scraper and making it convenient for maintenance and replacement. This solves the problem that existing devices require multiple tools to disassemble and are not easy to disassemble, thus improving the convenience of the device. Attached Figure Description

Detailed Implementation

[0033] 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.

[0034] Reference Figures 1-3 This utility model provides an embodiment of a scraper conveyor, including a conveyor 1. The top of the conveyor 1 has an inlet 3, which is funnel-shaped and made of stainless steel. Its inclined inner wall design helps the material slide smoothly into the conveyor 1, improving the feeding efficiency. A motor 2 is fixedly connected to the outer wall of the conveyor 1. The output end of the motor 2 is fixedly connected to a conveyor chain 5. The conveyor chain 5 is composed of multiple high-strength chain links. These chain links are usually forged from alloy steel and have undergone special heat treatment processes, which gives them high hardness and wear resistance. They can withstand the weight of the material and friction during transportation. A scraper 7 is provided at the top of the conveyor chain 5. The scraper 7 is made of high-strength wear-resistant rubber and a metal skeleton. This structure ensures the flexibility of the scraper 7, allowing it to better fit the conveyor belt, while also having sufficient strength to scrape off the material. A telescopic component is provided at the bottom of the scraper 7.

[0035] The telescopic assembly includes a telescopic plate 8 and a spring 11. The top of the telescopic plate 8 is fixedly connected to the bottom of the scraper 7. A connecting plate 4 is provided on the outer wall of the conveyor chain 5. A disassembly assembly is provided on the top of the connecting plate 4. A limit plate 9 is fixedly connected to the bottom of the telescopic plate 8. The limit plate 9 is made of carbon steel and its outer wall can also slide inside the connecting plate 4, playing a role in limiting and guiding. The outer wall of the limit plate 9 is slidably connected to the inside of the connecting plate 4. A fixing post 10 is fixedly connected to the inner wall of the connecting plate 4. The outer wall of the fixing post 10 is slidably connected to the inside of the telescopic plate 8. A spring 11 is provided inside the connecting plate 4. The spring 11 is a cylindrical helical compression spring made of high-quality spring steel, with good elasticity and fatigue life. Its top is fixedly connected to the bottom of the limit plate 9 and its bottom is fixedly connected to the inner wall of the connecting plate 4. It can provide elastic support when the scraper 7 moves, making it better adaptable to different situations. The top of the spring 11 is fixedly connected to the bottom of the limit plate 9 and its bottom is fixedly connected to the inner wall of the connecting plate 4.

[0036] Specifically, scraper conveyors play a crucial role in the material transportation process of industrial production. When material transportation begins, operators first place the material orderly into the conveyor 1 through the feed inlet 3, then start the motor 2. The motor 2 starts running and outputs power, driving the conveyor chain 5 to start running. The operation of the conveyor chain 5 causes the scraper 7 connected to it to move. During the movement, the scraper 7 comes into contact with the material, thus moving the material together, thereby realizing the transportation of the material. During the continuous movement of the scraper 7, the height of the conveyor belt may change due to uneven material distribution or equipment vibration. At this time, the spring 11 will compress or rebound according to the actual situation. This action of the spring 11 causes the limiting plate 9 to slide inside the connecting plate 4. At the same time, the fixed column 10 also slides inside the telescopic plate 8. The sliding of the fixed column 10 plays a limiting role on the telescopic plate 8, allowing the scraper 7 to adaptively adjust to adapt to various working conditions and ensure efficient and stable material transportation.

[0037] Reference Figure 2 , Figure 4 and Figure 5 The assembly and disassembly components include a locking post 19, made of high-strength alloy steel. This material has excellent hardness and wear resistance, and can withstand frequent insertion, removal, and rotation operations. The locking post 19 is located at the bottom of the connecting plate 4. A fixing plate 16 is fixedly connected to the outer wall of the transport chain 5. A clamping plate 17 is located at the bottom of the fixing plate 16. The clamping plate 17 is also made of stainless steel and cooperates with the fixing plate 16 to form a stable clamping structure. A sliding groove 21 is opened inside the fixing plate 16, and a sliding groove 21 and a locking groove 20 are opened inside the clamping plate 17. A hollow column 6 is fixedly connected to the top of the connecting plate 4. The hollow column 6 has a sliding groove inside. The connecting column 14 is connected to the movable connection. A knob 13 is fixedly connected to the outer wall of the connecting column 14. The knob 13 is made of plastic and has anti-slip texture on the surface for easy gripping and rotation by the operator. A sliding column 18 is fixedly connected to the bottom of the connecting column 14. The bottom end of the sliding column 18 is fixedly connected to the top of the locking column 19. The outer wall of the locking column 19 is slidably connected to the inside of the locking groove 20. A limiting ring 12 is rotatably connected to the outer wall of the connecting column 14. The outer wall of the limiting ring 12 is slidably connected to the inside of the hollow column 6. A second spring 15 is sleeved on the outer wall of the connecting column 14. The top of the second spring 15 is fixedly connected to the outer wall of the limiting ring 12, and the bottom of the second spring 15 is fixedly connected to the inside of the hollow column 6.

[0038] Specifically, during the long-term use of the scraper conveyor, the scraper 7, as a key component that directly contacts the material and undertakes the transportation task, is easily damaged due to frequent friction and collision. When signs of damage are found on the scraper 7, it needs to be maintained or replaced in time. At this time, the operator can push the knob 13. The movement of the knob 13 will drive the connected column 14 to move downward. The downward movement of the connected column 14 will drive the sliding column 18 to move downward. The sliding column 18 will then drive the locking column 19 to slide out of the locking groove 20. At the same time, the limit on the connected column 14 The ring 12 slides inside the hollow column 6, compressing the second spring 15 during the sliding process. Then, the knob 13 is turned, which drives the connecting column 14 to rotate, causing the locking column 19 to rotate as well. When the locking column 19 rotates to align with the sliding groove 21, the knob 13 is released. At this time, the compressed second spring 15 will rebound, causing the locking column 19 to slide out from inside the sliding groove 21. In this way, the connecting plate 4 can be removed smoothly, and the scraper 7 can be maintained or replaced to ensure that the scraper conveyor can operate continuously and stably.

[0039] Working principle: When transporting materials, the materials are placed inside the conveyor 1 through the feed port 3. Then, the motor 2 is started, which drives the conveyor chain 5 to move the scraper 7, thereby moving the materials for transportation. When the scraper 7 moves, the compression and rebound of the spring 11 causes the limiting plate 9 to slide inside the connecting plate 4. At the same time, the fixing column 10 slides inside the telescopic plate 8 to limit the telescopic plate 8, thereby adaptively adjusting the position of the scraper 7 to adapt to different situations.

[0040] Additionally, when used for an extended period, the scraper 7 is prone to damage. In this case, the knob 13 can be pushed, which will cause the connecting column 14 to move downwards. Then, the connecting column 14 will cause the sliding column 18 to move downwards, causing the locking column 19 to slide out of the slot 20. This will also cause the limiting ring 12 to slide inside the hollow column 6, compressing the second spring 15. Then, the knob 13 can be rotated, which will cause the connecting column 14 to rotate, thereby causing the locking column 19 to rotate and align with the sliding groove 21. After that, the knob 13 can be released, and the second spring 15 will rebound, causing the locking column 19 to slide out of the sliding groove 21. Only then can the connecting plate 4 be removed for maintenance or replacement.

[0041] 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.
