Description

Technical Field

[0001] This utility model relates to the field of coal gangue sorting technology, and in particular to a coal gangue sorting device. Background Technology

[0002] In the coal mining and processing industry, coal gangue, as a common solid waste, requires efficient sorting and separation, which has always been a key link in improving the utilization rate of coal resources and reducing environmental pollution.

[0003] Coal gangue sorting devices mostly use vibrating screens with fixed angles or simple gravity separation structures. Their adjustment performance is limited, making it difficult to adapt to the differences in coal gangue particle size generated in different mining areas and at different mining stages. For example, for coal gangue with smaller particle size, vibration with fixed amplitude can easily lead to incomplete sorting, with some gangue mixed into the coal. On the other hand, for gangue with larger particle size, rigid support sorting structures may experience blockage or low sorting efficiency due to insufficient vibration intensity. Therefore, in order to solve this problem, we propose a coal gangue sorting device. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a coal gangue sorting device that allows the linear lifting and lowering movement of the telescopic rod, combined with the elastic support of the first spring and the support plate, to flexibly adjust the tilt angle and vibration amplitude of the machine body, adapt to the sorting needs of coal gangue of different sizes, improve sorting efficiency, reduce the wear of the inner wall of the feed box and the tilting plate, extend the service life of the equipment, and also avoid material breakage caused by violent impact, thus ensuring the original shape of the coal gangue.

[0005] This utility model also provides a coal gangue sorting device as described above, including a machine body. Two fixing plates are fixedly installed on both sides of the machine body. A first spring is fixedly installed below the fixing plates. A bracket is fixedly installed below the first spring. A support plate is hinged inside the bracket.

One end of the threaded rod extends to the bottom of the base and is fixedly connected to a first transmission wheel. A feed box is fixedly installed above the machine body. A vibration motor is fixedly installed below the machine body.

[0006] According to the present invention, a coal gangue sorting device is provided, wherein the telescopic rod is movably fitted inside the sleeve, the telescopic rod has an internal thread, the threaded rod has an external thread, and the telescopic rod is threadedly connected to the threaded rod.

[0007] According to the present invention, a coal gangue sorting device has two servo motors fixedly installed on the top of the base, and the output shaft of the servo motor extends to the bottom of the base where a second transmission wheel is fixedly installed.

[0008] According to the coal gangue sorting device of this utility model, the first drive wheel and the second drive wheel are provided with belts on their exteriors, and the first drive wheel and the second drive wheel are connected by belt drive.

[0009] According to the present invention, a coal gangue sorting device is provided with a feed inlet at the top of the feed box, and limit plates are fixedly installed on both sides of the inside of the feed box.

[0013] Beneficial effects:

[0014] 1. The coal gangue sorting device of this technical solution uses a servo motor to drive the threaded rod to rotate stably. The threaded connection structure between the threaded rod and the telescopic rod enables the linear lifting and lowering motion of the telescopic rod. Combined with the elastic support of the first spring and the support plate, the tilt angle and vibration amplitude of the machine body can be flexibly adjusted to meet the sorting needs of coal gangue of different sizes and improve sorting efficiency.

[0015] 2. When materials such as coal gangue are fed into the feed inlet, they will first come into contact with the inclined plate. The inclination angle of the inclined plate can guide the material to slide down the plate surface, avoiding the material from directly impacting the inner wall of the feed box vertically. At the same time, the second spring under the inclined plate will undergo elastic deformation due to the impact force of the material, converting the kinetic energy of the falling material into the elastic potential energy of the spring. This greatly reduces the impact force of the material on the feed box and the inclined plate itself, reduces the wear of the inner wall of the feed box and the inclined plate, extends the service life of the equipment, and also avoids material breakage caused by violent impact, ensuring the original shape of the coal gangue.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-5This utility model discloses a coal gangue sorting device, comprising a body 1 for easy sorting of coal gangue. Two fixed plates 2 are fixedly installed on both sides of the body 1. The fixed plates 2 are compressible for a first spring 3. The first spring 3 is fixedly installed below the fixed plates 2, allowing for vibration due to its elasticity. A bracket 4 is fixedly installed below the first spring 3, supporting the movement of the body 1. A support plate 5 is hinged inside the bracket 4, allowing for easy adjustment of the angle of the body 1. A telescopic rod 21 is provided below the support plate 5, allowing for adjustment of the angle and extension / retraction of the body 1. A sleeve 6 is provided on the outside of the telescopic rod 21, which facilitates the extension and retraction of the telescopic rod 21. A base 7 is fixedly installed below the sleeve 6, through which the machine body 1 can be placed. A threaded rod 8 is provided inside the sleeve 6, through which the telescopic rod 21 can be raised and lowered. One end of the threaded rod 8 extends to the bottom of the base 7 and is fixedly connected to a first transmission wheel 9, through which the first transmission wheel 9 can drive the threaded rod 8 to rotate. A feed box 10 is fixedly installed on the top of the machine body 1, through which coal gangue can be fed into the interior of the machine body 1. A vibration motor 14 is fixedly installed on the bottom of the machine body 1, through which the vibration motor 14 can sort the coal gangue.

[0026] Specifically, the telescopic rod 21 is movably fitted inside the sleeve 6. The telescopic rod 21 has an internal thread, and the threaded rod 8 has an external thread. The telescopic rod 21 is threadedly connected to the threaded rod 8. The telescopic rod 21 can be raised and lowered through the threaded connection between the telescopic rod 21 and the threaded rod 8.

[0027] Specifically, two servo motors 11 are fixedly installed on the top of the base 7. The output shaft of the servo motor 11 extends to the bottom of the base 7 and a second transmission wheel 12 is fixedly installed thereon. The servo motor 11 can drive the second transmission wheel 12 to rotate.

[0028] Specifically, the first drive wheel 9 and the second drive wheel 12 are provided with a belt 13 on their exteriors. The first drive wheel 9 and the second drive wheel 12 are connected by the belt 13, and the belt 13 can drive the first drive wheel 9 to rotate.

[0029] Specifically, a feed inlet 19 is provided on the top of the feed box 10. The feed inlet 19 can feed coal gangue into the feed box 10. Limiting plates 15 are fixedly installed on both sides of the feed box 10. The sliding rod 16 can be limited by the limiting plates 15. The sliding rod 16 is movably fitted inside the limiting plates 15. The sliding rod 16 can facilitate the movement of the tilting plate 17. The tilting plate 17 is fixedly installed above the sliding rod 16. The tilting plate 17 can prevent coal gangue from falling directly into the machine body 1.

[0030] Specifically, a second spring 18 is fixedly installed above the limiting plate 15. One end of the second spring 18 is fixedly connected to the inclined plate 17. The second spring 18 is located outside the sliding rod 16. The inclined plate 17 can be reset by the elastic effect of the second spring 18.

[0031] Specifically, the machine body 1 is equipped with a screening screen 20, which can be used to screen coal gangue. The screening screen 20 has multiple screening holes. One end of the machine body 1 has two discharge ports, through which the sorted coal gangue can be discharged separately.

[0032] Specifically, a positioning plate is fixedly installed on the top of the telescopic rod 21, and one end of the positioning plate is fixedly connected to the support plate 5. The positioning plate can prevent the telescopic rod 21 from moving excessively.

[0033] Working Principle: Based on the size requirements of the coal gangue to be sorted, the servo motor 11 above the base 7 is started. The output shaft of the servo motor 11 drives the second transmission wheel 12, which extends to the bottom of the base 7, to rotate. Since the first transmission wheel 9 and the second transmission wheel 12 are connected by an external belt 13, the second transmission wheel 12 will drive the first transmission wheel 9 to rotate, thereby causing the threaded rod 8, which is fixedly connected to the first transmission wheel 9 and located inside the sleeve 6, to rotate stably. Because the telescopic rod 21 is movably fitted inside the sleeve 6, and the internal thread inside the telescopic rod 21 is threadedly connected to the external thread outside the threaded rod 8, the rotation of the threaded rod 8 will be converted into the linear lifting and lowering motion of the telescopic rod 21. The telescopic rod 21 is fixedly connected to the support plate 5 through a positioning plate. The support plate 5 is hinged inside the bracket 4. At the same time, the bracket 4 is connected to the fixed plates 2 on both sides of the machine body 1 through the first spring 3. Therefore, the lifting and lowering of the telescopic rod 21 will cooperate with the elastic support of the first spring 3 and the support plate 5 to flexibly adjust the tilt angle and vibration amplitude of the machine body 1. Then, the coal gangue and other materials are fed from the feed. The material is fed into the feed inlet 19 at the top of the feed box 10. The material first contacts the inclined plate 17 inside the feed box 10. The inclined angle of the inclined plate 17 guides the material to slide down the plate surface, preventing the material from directly impacting the inner wall of the feed box 10. Simultaneously, the sliding rod 16 below the inclined plate 17 is movably fitted inside the limiting plate 15. The limiting plate 15 is fixed to both sides inside the feed box 10. One end of the second spring 18 above the limiting plate 15 is fixedly connected to the inclined plate 17 and fitted outside the sliding rod 16. The impact force of the material will cause the second spring... Spring 18 generates elastic deformation, converting kinetic energy into elastic potential energy and weakening the impact force. Subsequently, the material enters the machine body 1 and starts the vibration motor 14 below the machine body 1. The vibration motor 14 drives the machine body 1 to vibrate, and the screening screen 20 inside the machine body 1, which has multiple screening holes, vibrates accordingly to screen the material. Smaller coal gangue will fall through the screening holes, while larger coal gangue will remain on the screening screen 20. Finally, coal gangue of different sizes will be discharged from the two discharge ports opened at one end of the machine body 1, completing the sorting work.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
