Description

Technical Field

[0001] The utility model belongs to the technical field of coal mining, and particularly relates to an intelligent separator for coal mining. Background Art

[0002] A coal mine is an area where humans mine coal resources in coal-rich mining areas. Generally, it is divided into underground coal mines and surface coal mines. When the coal seam is far from the surface, generally, underground roadways are dug to extract coal, which is an underground coal mine. When the coal seam is very close to the surface, generally, the surface soil layer is directly stripped to excavate coal, which is a surface coal mine. However, the mined coal blocks need to be sorted.

[0003] The utility model with Chinese application number 202022171085.3 discloses a sorting device for coal mines, including a device main body. A feed inlet is arranged at the top of the device main body. A sieve mesh is arranged inside the device main body. A brush block is arranged on the top of the sieve mesh. A brush hair is fixedly connected to the bottom of the brush block. The bottom end of the brush hair is attached to the top surface of the sieve mesh. A movable rod is fixedly connected to the right end of the brush block. A spray head is fixedly connected to the left side of the movable rod. A water pipe is fixedly connected to the top of the spray head. One end of the water pipe far from the spray head is fixedly connected to a water pump. However, in the actual use process, since the sizes of the coal blocks required for coal mines are different, when coal blocks of a specific size are needed, the filter plate needs to be replaced, resulting in mechanical shutdown and reduced production efficiency, and thus the practicability of the device is relatively low.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] Please refer to Figure 1 - Figure 4, the present utility model provides a technical solution: an intelligent sorting machine for coal mine mining, including a connection box 1. One side of the connection box 1 is connected with two support plates 2, and an adjusting device 5 is arranged between the two support plates 2. The adjusting device 5 includes a lower sieve plate 504. Both sides of the inner wall of the lower sieve plate 504 are provided with sliding grooves 505, and sliders 510 are slidably connected in the sliding grooves 505. The same upper sieve plate 507 is connected between the two sliders 510. The top of the lower sieve plate 504 is connected with a threaded seat 503, and a threaded rod 502 is threadedly connected in the threaded seat 503. One end of the threaded rod 502 is connected with a rotating plate 501, and a fixed block 506 is connected to the top of the upper sieve plate 507. Both sides of the lower sieve plate 504 are connected with two movable blocks 508. A transmission device 6 is arranged in the connection box 1. A baffle 509 is connected to the top of the upper sieve plate 507. The bottom of the upper sieve plate 507 is in contact with the top of the lower sieve plate 504. Both sides of the lower sieve plate 504 are respectively slidably connected with one side of the opposite surfaces of the two support plates 2. Two movable grooves 7 are respectively opened on one side of the opposite surfaces of the two support plates 2. The inner wall of the movable groove 7 is slidably connected with the outer wall of the movable block 508. One side of the fixed block 506 is rotatably connected with one end of the threaded rod 502 away from the rotating plate 501. The transmission device 6 includes a second motor 604 and a moving frame 601. A transmission rod 602 is movably connected to the inner wall of the moving frame 601. The output shaft of the second motor 604 is connected with a turntable 605. One side of the moving frame 601 is connected with a connecting rod 603. One end of the connecting rod 603 is connected with a connecting block 606. The bottom of the transmission rod 602 is connected with the top of the turntable 605. A sliding sleeve is embedded on one side of the connection box 1. The outer wall of the connecting rod 603 is slidably connected with the inner part of the sliding sleeve. The top of the connecting block 606 is connected with the bottom of the lower sieve plate 504. The bottom of the second motor 604 is fixedly installed on the bottom of the inner wall of the connection box 1 through a mounting plate.

[0026] The specific implementation manner is as follows. By setting the slider 510 to slide in the sliding groove 505, the movement of the upper sieve plate 507 is made more stable, avoiding deviation and causing jamming to affect the operation. By setting the baffle 509, the baffle 509 blocks to prevent coal blocks from falling from the other side of the upper sieve plate 507 and jamming the lower sieve plate 504, thereby further ensuring the normal operation of the device.

[0027] One side of one of the support plates 2 is connected with a knocking device 4. The knocking device 4 includes a first motor 401. The output shaft of the first motor 401 is connected with a rotating rod 402. Two cams 403 are connected to the outer wall of the rotating rod 402. The same filter plate 3 is connected between the two support plates 2. The filter plate 3 is located at the bottom of the lower sieve plate 504. One side of the first motor 401 is fixedly installed on one side of one of the support plates 2. The output shaft of the first motor 401 penetrates the support plate 2. The other end of the rotating rod 402 is rotatably connected with one side of the other support plate 2. The bottom of the filter plate 3 is in contact with the outer wall of the cam 403.

[0028] Specific implementation method: By setting the cam 403 as a multi-bump cam 403, the vibration frequency can be increased, and the vibration effect is improved compared with the traditional single-point contact, which is beneficial to fully knocking the coal blocks, making the slag on the surface of the coal blocks fall off more cleanly.

[0029] Working principle: During use, the coal blocks fall from the top of the upper sieve plate 507, and then the second motor 604 drives the turntable 605 to rotate, so that the turntable 605 drives the transmission rod 602 to rotate, and the transmission rod 602 drives the moving frame 601 to move. The moving frame 601 drives the connecting block 606 to move left and right reciprocally through the connecting rod 603, so that the lower sieve plate 504 and the upper sieve plate 507 screen the coal blocks. When specific coal block sizes are required, the rotating plate 501 is rotated to drive the threaded rod 502 to rotate, so that the threaded rod 502 moves through the threaded seat 503, and then the threaded rod 502 drives the upper sieve plate 507 to move through the fixing block 506, making the sieve holes between the upper sieve plate 507 and the lower sieve plate 504 misaligned, thereby changing the size of the screening holes, so as to realize the screening of coal blocks with different requirements. Finally, the screened coal blocks fall onto the filter plate 3, and the first motor 401 drives the rotating rod 402 to rotate, so that the rotating rod 402 hits the filter plate 3 through the cam 403, making the slag on the surface of the coal blocks fall off, ensuring the cleanliness of the surface of the coal blocks and facilitating subsequent use.
