Description

Technical Field

[0001] The utility model relates to the technical field of coal gangue, and specifically, to a material selection device for using coal gangue to fill a highway subgrade. Background Art

[0002] Coal gangue is a kind of solid waste generated during the coal mining process. It is mainly composed of coal, rocks and other minerals that have not been extracted from the coal seam. During the coal mining and processing process, coal gangue is often generated as waste and piled up in the yard near the coal mine.

[0003] However, due to the small compression coefficient and high compression modulus of coal gangue, it can provide certain structural strength and stability, enabling the subgrade to bear the load of transportation, helping to reduce the settlement and deformation of the subgrade. At the same time, it has certain drainage performance, which can help manage and drain the groundwater under the road surface, avoid damage to the road surface due to waterlogging, extend the service life of the highway, and effectively utilize this waste resource, which is beneficial to environmental protection and resource conservation.

[0004] The size of the coal gangue used for highway subgrade paving is generally between 20 mm and 75 mm. The coal gangue particles within this range help to form a uniform subgrade structure during the filling process, improving the bearing capacity and stability of the subgrade. Larger coal gangue particles may lead to poor compaction effect of the subgrade during the filling process, affecting the overall compaction performance and reducing the bearing capacity and stability of the subgrade. Coal gangue particles with smaller volume are likely to cause uneven internal structure of the subgrade, with a large number of small voids appearing in the filled structure, resulting in a decrease in the overall stability of the subgrade and increasing the risk of road surface deformation and settlement. Traditional coal gangue separation methods mostly rely on manual or simple mechanical screening, which have problems such as low separation efficiency, high energy consumption and high labor intensity.

[0005] Therefore, we make improvements and propose a material selection device for using coal gangue to fill a highway subgrade. Content of the Utility Model

An inlet 11 is provided on the upper surface of the box body 1. A first screening plate 12 is rotatably connected to the left side of the inner surface of the box body 1 through a rotating shaft. A second screening plate 13 is rotatably connected to the right side of the inner surface of the box body 1 through a rotating shaft. Two first installation grooves 2 are provided on both sides inside the box body 1. A lifting member for assisting the first screening plate 12 and the second screening plate 13 in screening is slidably connected to the inner surface of the first installation groove 2. A collecting member is arranged on the inner bottom surface of the box body 1. Rotating shafts 5 are fixedly connected to both the left and right sides of the box body 1. A fixing member for fixing the collecting member is rotatably connected to the outer surface of the rotating shaft 5. The lifting member includes a first lifting block 22 and a second lifting block 28. Two second installation grooves 21 are provided on both the left and right sides inside the box body 1. The first lifting block 22 and the second lifting block 28 are both slidably arranged inside the first installation groove 2. Moving grooves 23 are provided at the lower ends of the first lifting block 22 and the second lifting block 28. A sliding rod 24 is slidably connected to the inner surface of the moving groove 23. One end of the sliding rod 24 is fixedly connected to a rotating plate 25. One end of the rotating plate 25 is rotatably connected to the box body 1. The upper ends of the first lifting block 22 and the second lifting block 28 are rotatably connected to a slider 26 through a rotating shaft. Sliding grooves 27 are provided on both sides of the right end of the first screening plate 12 and both sides of the left end of the second screening plate 13. The slider 26 is slidably arranged inside the sliding groove 27. Protective boxes 3 are fixedly connected to both the front and rear sides of the box body 1. A motor 31 is fixedly connected to one end of the outer surface of the protective box 3. The output end of the motor 31 extends into the protective box 3 and is fixedly connected to a first synchronous pulley 32. A synchronous belt 33 is meshed with the outer surface of the first synchronous pulley 32. A second synchronous pulley 34 is meshed with the inner surface of the synchronous belt 33. The synchronous belt 33 and the second synchronous pulley 34 are both fixedly connected to one end of the rotating plate 25.

[0047] Implementation process: The motor 31 starts to work and drives the first synchronous pulley 32 to rotate. The rotation of the first synchronous pulley 32 drives the second synchronous pulley 34, which is synchronously connected to it through the synchronous belt 33, to rotate synchronously. The rotation of the first synchronous pulley 32 and the second synchronous pulley 34 drives the two rotating plates 25 to rotate synchronously around the center lines of the first synchronous pulley 32 and the second synchronous pulley 34 respectively. Since the first lifting block 22 and the second lifting block 28 are both slidably arranged inside the first installation groove 2, and the slide rod 24 fixedly connected to one end of the rotating plate 25 is slidably arranged inside the movable groove 23, the rotation of the rotating plate 25 drives the first lifting block 22 and the second lifting block 28 to perform reciprocating up and down movements. At the same time, because the first lifting block 22 is rotatably connected to the slider 26, and the slider 26 is slidably arranged inside the sliding groove 27, when the first lifting block 22 moves upward, it drives the second screening plate 13 to rotate upward clockwise around the rotating shaft, and when the first lifting block 22 moves downward, it drives the second screening plate 13 to rotate downward counterclockwise around the rotating shaft. When the second lifting block 28 moves upward, it drives the first screening plate 12 to rotate upward counterclockwise around the rotating shaft, and when the second lifting block 28 moves downward, it drives the first screening plate 12 to rotate downward clockwise around the rotating shaft, that is, it drives the first screening plate 12 and the second screening plate 13 to rotate reciprocally around their own rotating shafts. The coal gangue falls on the upper surface of the first screening plate 12 through the feed inlet 11. The larger coal gangue falls inside the first collection box 4 through the reciprocating rotation of the first screening plate 12. The medium-sized coal gangue falls on the upper surface of the second screening plate 13 through the first screening plate 12, and then the medium-sized coal gangue falls inside the third collection box 42 through the reciprocating rotation of the second screening plate 13. The medium-sized coal gangue passes through the second screening plate 13 and falls inside the second collection box 41.

[0048] Benefits of implementation: It realizes the screening of coal gangue of different sizes.

[0049] Embodiment 2

[0050] The collection members include a first collection box 4, a second collection box 41, and a third collection box 42. The first collection box 4 is arranged at the right end of the inner bottom surface of the box body 1. The second collection box 41 is arranged at the central position of the inner bottom surface of the box body 1. The third collection box 42 is arranged at the left end of the inner bottom surface of the box body 1. Two fixing grooves are opened on the left side surface of the second collection box 41, and the third collection box 42 is slidably arranged inside the fixing grooves. Four wheels are installed on the lower surfaces of the first collection box 4, the second collection box 41, and the third collection box 42. Inclined surfaces 43 are opened on both sides of the inner bottom surface of the box body 1. The fixing members include a fixing rod 51, and the fixing rod 51 is rotatably connected to the rotating shaft 5. Clamping blocks 52 are fixedly connected to both the left and right sides of the box body 1.

[0051] Implementation process: When enough coal gangue has been screened inside the first collection box 4, the second collection box 41, and the third collection box 42, pull up the fixing rod 51 to rotate the fixing rod 51 out from the inner side of the clamping block 52 around the rotating shaft 5. Then, pull out the first collection box 4, the second collection box 41, and the third collection box 42 from the inner bottom surface of the box body 1. Subsequently, dump the coal gangue inside them for transportation. Since inclined surfaces 43 are provided on both sides of the inner bottom surface of the box body 1, it makes it easier to move the first collection box 4, the second collection box 41, and the third collection box 42. When it is necessary to put the first collection box 4, the second collection box 41, and the third collection box 42 back to their original positions, just operate in the reverse direction.
