Technical Field

[0001] This utility model relates to the technical field of coal mining equipment, specifically to a coal mine pillarless high-efficiency coal mining rock-blocking trolley. Background Technology

[0002] Coal is a fuel resource widely used in power generation, heating, industrial production and steelmaking, and is an important energy source. Coal mining requires the use of mining trolleys to penetrate deep underground to extract coal.

[0003] However, the existing coal mining trolleys have poor flexibility, requiring frequent adjustments to the mining angle, resulting in low mining efficiency. Furthermore, the angle of the receiving plate on the trolley is mostly fixed, which cannot effectively collect coal and makes it difficult to promote their use.

[0004] To address this problem, this application provides a high-efficiency coal mine pillarless mining trolley. Utility Model Content

[0005] The purpose of this utility model is to provide a coal mine pillarless high-efficiency coal mining trolley to solve the problems mentioned in the background art, such as poor flexibility of coal mining equipment, the need for frequent adjustment of the mining angle, the fixed angle of the receiving plate on the mining vehicle, resulting in low mining efficiency, and the inability to effectively collect coal, leading to poor performance.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A high-efficiency coal pillar-free mining trolley includes a support assembly, a steering assembly, and a mining assembly. The support assembly includes a support plate and movable wheels, with the movable wheels rotatably mounted on the bottom of the support plate. The steering assembly is located inside the support assembly and includes a motor, a gear ring, a drive shaft, and an auxiliary wheel. The gear ring is fixedly mounted on one end of the drive shaft, and the auxiliary wheel is fixedly mounted on the other end of the drive shaft. The mining assembly is located inside the support assembly and the steering assembly and includes a receiving plate and a hydraulic cylinder, with one end of the hydraulic cylinder rotatably mounted on both sides of the receiving plate.

[0017] The present invention will be further described in detail below with reference to embodiments: like Figure 1-5 As shown, this utility model provides a coal mine pillarless high-efficiency coal blocking trolley, including a support assembly 1, a steering assembly 2, and a mining assembly 3. The support assembly 1 includes a support plate 10 and a moving wheel 11. The moving wheel 11 is rotatably installed at the bottom of the support plate 10, and the equipment can be moved to the required position by the moving wheel 11. A fixing lug 12 is fixedly installed on the outside of the support plate 10, and a fixing plate 13 is fixedly installed on the top of the support plate 10. The fixing plate 13 limits the toothed ring 26 and the auxiliary wheel 27.

[0018] like Figure 2-5 As shown, the steering assembly 2 is located inside the support assembly 1. The steering assembly 2 includes a motor 20, a gear ring 26, a drive shaft 29, and an auxiliary wheel 27. The motor 20 is fixedly mounted on the top of the support plate 10. One end of the motor 20 is fixedly mounted with a drive pulley 21. The drive pulley 21 is movably connected to the outside of the drive pulley 21, and the other end of the drive belt 22 is movably connected with a driven pulley 23. A connecting roller 28 is rotatably mounted inside the fixed plate 13. A first gear 24 is fixedly mounted inside the driven pulley 23. A second gear 25 is meshed with the outside of the first gear 24. The gear ring 26 is meshed with the outside of the second gear 25 and is movably connected to the outside of the connecting roller 28. The motor 20 drives the drive pulley 21 to rotate, and then the drive pulley 21 drives the driven pulley 23 to rotate via the drive belt 22. Then, the driven pulley 23 drives the first gear 24 inside it to rotate, and then the first gear 24 drives the gear ring 26 to rotate inside the fixed plate 13 via the second gear 25.

[0019] like Figure 5As shown, the drive shaft 29 is rotatably mounted on the top of the support plate 10, the gear ring 26 is fixedly mounted on one end of the drive shaft 29, the auxiliary wheel 27 is fixedly mounted on the other end of the drive shaft 29, a connecting rod 201 is fixedly mounted on one side of the gear ring 26, and the other end of the connecting rod 201 is fixedly mounted on one side of the auxiliary wheel 27. A mounting plate 14 is fixedly mounted on the outside of the drive shaft 29, and the mounting plate 14 is fixedly mounted on the outside of the connecting rod 201. The gear ring 26 drives the auxiliary wheel 27 and the mounting plate 14 to rotate through the drive shaft 29 and the connecting rod 201, thereby adjusting the mining angle of the coal mining machine 30 to a suitable angle, increasing the mining range of the coal mining machine 30, reducing the frequency of adjusting the mining angle, and improving mining efficiency.

[0020] like Figure 2-5 As shown, the mining component 3 is located inside the support component 1 and the steering component 2. The mining component 3 includes a receiving plate 31 and a hydraulic cylinder 32. One end of the hydraulic cylinder 32 is rotatably mounted on both sides of the receiving plate 31. A coal mining machine 30 is fixedly mounted on the top of the mounting plate 14. The coal mining machine 30 is used to mine coal. The receiving plate 31 is rotatably mounted inside the fixed plate 13. The other end of the hydraulic cylinder 32 is rotatably mounted inside the fixed ear 12. The hydraulic cylinder 32 extends and pushes the receiving plate 31 to rotate inside the fixed plate 13, so that the receiving plate 31 can always maintain a suitable distance from the coal mining machine 30, thereby improving the coal collection efficiency. A coal collection bin 33 is fixedly mounted on the top of the support plate 10, through which coal is collected and stored.

[0021] The working principle of the coal mine's pillarless high-efficiency mining trolley will be explained in detail below.

[0022] like Figure 1-5 As shown, when using this coal mine pillarless high-efficiency coal mining trolley, the equipment is moved to the required position by the moving wheels 11. The motor 20 drives the drive pulley 21 to rotate, and the drive pulley 21 drives the driven pulley 23 to rotate through the transmission belt 22. The driven pulley 23 drives the first gear 24 inside it to rotate, and the first gear 24 drives the gear ring 26 to rotate inside the fixed plate 13 through the second gear 25. At the same time, the gear ring 26 drives the auxiliary wheel 27 and the mounting plate 14 to rotate through the transmission shaft 29 and the connecting rod 201, adjusting the mining angle of the coal mining machine 30 to a suitable angle. At the same time, the hydraulic cylinder 32 extends and pushes the receiving plate 31 to rotate inside the fixed plate 13, so that the receiving plate 31 can always maintain a suitable distance from the coal mining machine 30, improving the coal collection efficiency and driving the coal mining machine 30 to work and mine the coal. The mined coal falls on the receiving plate 31 and then rolls into the coal collection bin 33 for collection and storage.

[0023] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
