Description
Technical Field
[0001] This utility model relates to the field of loader technology, and in particular to an automatic coal-cleaning type mining loader. Background Technology
[0002] Mining loaders are key equipment in mining operations, primarily responsible for the efficient loading and transportation of materials such as ore and coal. This significantly improves mining efficiency, reduces labor costs, and provides strong support for the sustainable development of mining enterprises. With the continuous expansion of mining scale and increasing demands for production efficiency, the performance and functions of mining loaders are constantly being optimized and expanded. Modern mining loaders not only possess powerful loading capacity but have also made significant progress in reliability, ease of operation, and environmental adaptability, enabling them to better cope with complex and harsh mining environments and ensure the smooth extraction and transportation of mineral resources.
[0003] Traditional mining loaders are typically powered by an engine, with the wheels or tracks driven by a transmission system to move the machine. The bucket at the front of the loader is controlled by a hydraulic system for lifting, tilting, and digging. During operation, the loader moves to a material accumulation site, manipulates the bucket to scoop up the material, and then transports it to a designated location for unloading.
[0004] However, traditional mining loaders have certain shortcomings. In actual operation, when the loader bucket is loaded with materials such as coal, due to the swaying of the bucket and the incompleteness of the unloading process, coal often falls from the bucket to near the tires. As the operation continues, the fallen coal gradually accumulates around the tires. This not only increases the friction between the tires and the ground, leading to increased energy consumption when the equipment moves, but also affects the normal rotation of the tires, reduces the mobility and flexibility of the equipment, and may even cause tire failure, seriously affecting the normal use and operating efficiency of the equipment. Therefore, an automatic coal-clearing mining loader is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an automatic coal-collecting mining loader, which aims to improve the problem that coal easily falls from the bucket to the vicinity of the tires during the use of the equipment, thus affecting the movement of the equipment.

Detailed Implementation
[0032] 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.
[0033] Reference Figures 1-3 The present invention provides an embodiment of an automatic coal-cutting mine loader, comprising a loader 1, wherein the loader 1 is used for excavating coal mines, the bottom of the loader 1 is provided with a cleaning component, and the top of the loader 1 is provided with a dust removal component;
[0034] The cleaning assembly includes a sweeping plate 13, which is located at the bottom of the loader 1. The sweeping plate 13 is used to directly contact and remove dirt, ore debris, and other debris accumulated at the bottom of the loader 1 during operation. It is made of a wear-resistant and flexible material, such as rubber or high-strength plastic composite material, which can effectively scrape away debris without damaging the bottom of the loader 1, ensuring the cleanliness of the bottom of the loader 1 and reducing the adverse effects of debris accumulation on equipment operation. A fixing frame 2 is fixedly connected to the bottom of the loader 1. The fixing frame 2 serves as a connection and support, providing a stable installation foundation for the upper fixing base 3 and the entire cleaning assembly. It firmly fixes the cleaning assembly to the loader 1, ensuring that the cleaning assembly will not shift or loosen during the movement and operation of the loader 1, thus ensuring the stability and reliability of the cleaning work. The fixing base 3 is fixedly connected to the top of the fixing frame 2. A motor 4 is fixedly connected internally. A connecting block 6 is fixedly connected to the output end of the motor 4. A connecting block 7 is rotatably connected inside the connecting block 6. Sliding columns 8 are fixedly connected to both sides of the connecting block 7. Under the rotation of the connecting block 6, the connecting block 7 drives the sliding columns 8 to reciprocate. A fixing frame 5 is fixedly connected to the inner wall of the fixing frame 2. A rotating shaft 12 is fixedly connected inside the fixing frame 2. A square connecting plate 11 is rotatably connected to the outer wall of the rotating shaft 12. Arc-shaped connecting plates 9 are fixedly connected to both sides of the square connecting plate 11. Each arc-shaped connecting plate 9 has a sliding groove 10 inside. Each sliding column 8 is slidably connected to the inner wall of the sliding groove 10. The rotating shaft 12 serves as the rotation center of the square connecting plate 11, allowing the square connecting plate 11 to swing around the rotating shaft 12, cooperating with the sliding of the sliding columns 8 in the sliding groove 10. One side of the square connecting plate 11 is fixedly connected to the outer wall of the cleaning plate 13.
[0035] Specifically, during equipment use, coal may easily fall from the bucket of the equipment during loading or transportation. When motor 4 is started, it drives connecting block 6 to rotate through its output end. The rotation of connecting block 6 transmits power to connecting block 7, causing the sliding columns 8 on both sides of connecting block 7 to slide on the inner wall of the sliding groove 10. During the sliding of the sliding columns 8, the square connecting plate 11 is also driven and begins to rotate back and forth around the rotating shaft 12. The reciprocating rotation of the square connecting plate 11 is generated by the interaction between the sliding columns 8 and the sliding groove 10, and this movement transmits force to the cleaning plate 13. The cleaning plate 13, through its bottom bristles, can effectively clean up the coal that has fallen to the bottom of the loader 1, especially around the tires. The cleaning plate 13 can continuously clean the coal around the tires during equipment operation, preventing coal from accumulating on the tire surface, thereby reducing the obstruction of tire rotation by coal and preventing equipment malfunction or tire wear caused by coal accumulation. At this point, the bristles at the bottom of the cleaning plate 13 rub against the coal, causing it to be swept to one side. This ensures that the coal does not interfere with the normal rotation of the tires, improving the equipment's mobility and operational efficiency, and ensuring stable operation and efficient movement. Furthermore, it effectively extends the lifespan of the equipment tires and reduces wear caused by friction between the coal and the tires.
[0036] Reference Figure 1 and Figure 4The dust removal assembly includes an atomizing nozzle 25, located on the top of the loader 1. The atomizing nozzle 25 is a key component for atomizing water and spraying it into the air. Through a special nozzle structure design, it disperses the water flow into tiny droplets, increasing the contact area between water and dust particles, making it easier for dust to be adsorbed and captured by the water mist. A water tank 14 is fixedly connected to the top of the loader 1. A connecting pipe 15 is fixedly connected inside the water tank 14. One end of the connecting pipe 15 is fixedly connected to the inside of the atomizing nozzle 25. A second motor 17 is fixedly connected to one side of the water tank 14. A transmission plate 18 is fixedly connected to the output end of the second motor 17. A first connecting column 19 is rotatably connected inside the transmission plate 18. The transmission plate 18 connects the second motor 17 and the first connecting column 19, transmitting the rotational motion of the second motor 17 to the first connecting column 19. The rotation of the connecting column 19 drives the connecting column 19 to make a circular motion. One end of the connecting column 19 is fixedly connected to the sleeve 20. The connecting column 19 makes a circular motion under the drive of the transmission plate 18. At the same time, through the connection with the sleeve 20, the circular motion is transmitted to the sleeve 20 and provides certain support and guidance for the movement of the sleeve 20, ensuring that the sleeve 20 can stably follow the movement of the connecting column 19. The sleeve 20 is slidably connected to the connecting column 21. Both ends of the connecting column 21 are fixedly connected to the square connecting plate 22. The square connecting plate 22 is fixedly connected to the connecting shaft 23. Both ends of the connecting shaft 23 are rotatably connected to the fixing plate 16. One side of the fixing plate 16 is fixedly connected to the outer wall of the water tank 14. The outer wall of the connecting shaft 23 is fixedly connected to the connecting block 24. The top of the connecting block 24 is fixedly connected to the bottom of the atomizing nozzle 25.
[0037] Specifically, during normal operation of the equipment, a large amount of dust is often suspended in the air, especially in some industrial or operational environments. This dust can adversely affect the performance of the equipment and the health of the workers. At this time, the water pump delivers water from the water tank 14 to the atomizing nozzle 25 through the connecting pipe 15. The design of the atomizing nozzle 25 allows the water to be quickly atomized into fine water mist, forming uniform water mist particles that are sprayed into the air. These water mist particles adsorb dust in the air, helping it to settle, thus avoiding the problem of dust remaining suspended in the air for a long time. As the water mist is sprayed, the dust particles combine with the water mist, reducing the concentration of dust in the air, thereby creating a cleaner and safer working environment for the workers. Subsequently, the second motor 17 is started. The second motor 17 drives the transmission plate 18 to rotate through the output end, so that the transmission plate 18 can drive the first connecting column 19 to move along a certain trajectory. The connection between the first connecting column 19 and the sleeve 20 allows the sleeve 20 to slide smoothly on the outer wall of the second connecting column 21. As the sleeve 20 slides, the movement of the connecting column 19 causes the square connecting plates 22 on both sides to rotate around the connecting shaft 23. The power generated by this rotation is transmitted through the connecting shaft 23 to the surface of the connecting block 24, which in turn drives the atomizing nozzle 25 to rotate back and forth. During the rotation, the atomizing nozzle 25 can expand its spray range, ensuring that the water mist covers a wider area, thereby improving the air purification effect. This rotation method not only increases the coverage area of the water mist, but also effectively prevents dust from being resuspended in the air, reducing the risk of workers being exposed to harmful dust.
[0038] Working Principle: During equipment use, coal will fall from the inside of the equipment bucket. At this time, motor 4 is started, and the output end of motor 4 drives connecting block 6 to rotate, causing the sliding columns 8 on both sides of connecting block 7 to slide on the inner wall of the sliding groove 10. During this process, the square connecting plate 11 will reciprocate left and right around the rotating shaft 12. This reciprocating rotation force will be transmitted to the surface of the cleaning plate 13. The brush bristles at the bottom of the cleaning plate 13 will sweep away the coal that has fallen near the bottom tires of the loader 1, preventing the coal from obstructing the rotation of the tires and enhancing the mobility of the equipment. During equipment use, a large amount of dust will float in the air. At this time, the water pump will transfer the water in the water tank 14 to the atomizing nozzle 25 through the connecting pipe 15. The water is atomized by the atomizing nozzle 25 and sprayed out. The fine water mist adsorbs dust in the air, preventing dust from floating in the air for a long time. Then, the motor 217 is started, and the output end of the motor 217 drives the transmission plate 18 to rotate. This drives the sleeve 20 to slide on the outer wall of the connecting column 21 through the connecting column 19, and pushes the two square connecting plates 22 on both sides to rotate around the connecting shaft 23. This rotational force is transmitted to the surface of the connecting block 24 through the connecting shaft 23, causing the atomizing nozzle 25 to rotate left and right, expanding the spray range of the atomizing nozzle 25, preventing dust from entering the workers' body through the air and causing harm to the workers, and enhancing the dust removal effect of the equipment.
[0039] 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.
