Description

Technical Field

[0001] The present invention relates to the field of coal mine transportation, and particularly to a conveyor for coal mine excavation. Background Art

[0002] Coal mining refers to the process of extracting coal resources from underground or the surface, which is the first step in coal production. The main purpose of coal mining is to extract the coal deposits underground for industrial production and energy utilization.

[0003] After coal mining, it is necessary to transport the coal to the ground or inside a transportation vehicle. Some existing transportation methods place the coal on a conveyor belt and use the translational movement of the conveyor belt to transport the coal. However, due to the large volume of the mined coal, directly placing it on the conveyor belt results in resistance during transportation, reducing the transportation speed and efficiency. Moreover, during the process of transporting coal by the conveyor belt, coal powder accumulates on the surface of the conveyor belt. At this time, it is necessary to stop the conveyor belt and manually clean the coal powder on the conveyor belt, which greatly reduces the efficiency of coal transportation. In addition, when transporting coal, sometimes it is necessary to transport the coal to different storage locations. At this time, the entire transportation device needs to be moved to change the transportation direction of the coal, and the device is not very convenient to use. Summary of the Invention

[0004] A conveyor for coal mine excavation provided by the present invention, when transporting coal, crushes the coal to improve the smoothness of coal transportation, reduces the friction during transportation, increases the transportation speed and efficiency, and has a high crushing efficiency of coal. When transporting coal, there is no need to manually clean the conveyor belt to prevent coal powder from accumulating on the conveyor belt, thereby improving the transportation efficiency of coal. When using the transportation device, the transportation direction of the coal can be adjusted without moving the entire device, improving the convenience of coal transportation.

[0005] In order to achieve the above object, the present invention adopts the following technical solution: A conveyor for coal mine excavation, comprising:

[0006] A bracket;

[0007] A crushing box, fixedly arranged on one side of the bracket, and two rotating rods are arranged on both sides of the inner wall of the crushing box through bearings, and the two rotating rods can rotate;

[0008] Two first gears, respectively fixedly sleeved on the outer surfaces of the two rotating rods, and the outer surfaces of the two first gears are meshed with each other. When one of the rotating rods rotates clockwise, it further drives the other first gear to rotate counterclockwise through one of the first gears, so that the other rotating rod rotates counterclockwise;

[0009] A bidirectional threaded rod is arranged on the inner walls on both sides of the crushing box through bearings. Two sleeves are sleeved on the outer surface of the bidirectional threaded rod in a threaded manner. There are two threaded grooves with different helix directions on the outer surface of the bidirectional threaded rod. The two sleeves are connected to the threaded grooves with different helix directions of the bidirectional threaded rod. The pressing plate can slide on the inner wall of the crushing box. Therefore, when the bidirectional threaded rod rotates counterclockwise, the two sleeves move in opposite directions on the outer surface of the bidirectional threaded rod. When the bidirectional threaded rod rotates clockwise, the two sleeves move away from each other on the outer surface of the bidirectional threaded rod.

[0010] Two transmission rods are respectively movably arranged in the inner walls of the two sleeves. A convex plate is movably arranged on one side of the two transmission rods. When the two sleeves move in opposite directions, the convex plate is pushed downward through the two transmission rods, further enabling the pressing plate to apply a downward pressure on the coal, making the coal contact the gap between the two crushing rollers faster and improving the efficiency of coal crushing.

[0011] As a further improvement of the present invention: Crushing rollers are fixedly sleeved on the outer surfaces of the two rotating rods. A bidirectional motor is installed on one side of the crushing box. The output shaft of the bidirectional motor is connected to one side of one of the rotating rods. A feed hopper is fixedly arranged on one side of the crushing box. A discharge bin is fixedly arranged on the side of the crushing box close to the support. A first pulley is fixedly arranged on one side of the convex plate. When the external power switch of the bidirectional motor is turned on, the output shaft of the bidirectional motor can rotate forward and backward. It is controlled that the output shaft of the bidirectional motor drives one of the rotating rods to rotate clockwise, and further drives the other first gear to rotate counterclockwise through one of the first gears, so that the other rotating rod rotates counterclockwise. At this time, the two crushing rollers rotate in opposite directions, and the two crushing rollers rotating in opposite directions crush the coal by extrusion.

[0012] As a further improvement of the present invention: A second pulley is fixedly sleeved on the outer surface of the other rotating rod. A belt is arranged on the outer surface of the second pulley. A first pulley is arranged on the inner wall of the belt. The first pulley is fixedly sleeved on the outer surface of the bidirectional threaded rod. When the other rotating rod rotates counterclockwise, it drives the second pulley to rotate counterclockwise, and drives the first pulley to rotate counterclockwise through the belt, further enabling the bidirectional threaded rod to rotate.

[0013] As a further improvement of the present invention: A conveyor belt is arranged on the inner wall of the support. Round rods are arranged on both sides of the inner wall of the support through bearings. A plurality of first telescopic rods are fixedly arranged on the outer surface of the round rods. The round rod can rotate through the bearing. When the round rod rotates, it drives the plurality of first telescopic rods to rotate.

[0014] As a further improvement of the present invention: a second telescopic rod is movably embedded in the inner wall of each of the plurality of first telescopic rods, and a spring is movably sleeved on the outer surface of each of the plurality of second telescopic rods. Each of the plurality of second telescopic rods can slide inside the inner wall of each of the plurality of first telescopic rods, and the plurality of springs have elasticity. At this time, the elasticity of the plurality of springs presses the plurality of brushes, so that the bristles of the plurality of brushes closely adhere to one side of the conveyor belt.

[0015] As a further improvement of the present invention: the plurality of second telescopic rods are grouped in pairs of two, and a brush is fixedly arranged on one side of each of the plurality of second telescopic rods. Two fixing rods are fixedly arranged on one side of the bracket. A driving motor is installed at the opposite ends of the two fixing rods. The output shaft of the driving motor is connected to one side of the round rod. A baffle is arranged on one side of the bracket by screws. The bristles of the plurality of brushes closely adhere to one side of the conveyor belt. At this time, turn on the external power switch of the driving motor. The two fixing rods support the driving motor, so that the driving motor is installed on the bracket. Further, the output shaft of the driving motor drives the round rod to rotate counterclockwise. Further, the plurality of first telescopic rods and the plurality of second telescopic rods drive the plurality of brushes to rotate counterclockwise. The counterclockwise rotating brushes contact the clockwise rotating conveyor belt to clean the conveyor belt and prevent coal powder from accumulating on the conveyor belt. By turning the plurality of screws on the baffle, the baffle can be removed from the bracket to replace the plurality of brushes and clean the inside of the bracket.

[0016] As a further improvement of the present invention: a support rod is fixedly arranged at the center of one side of the bracket. A second gear is fixedly sleeved on the outer surface of the support rod. A rack is meshed on the outer surface of the second gear. The second gear is provided with a base through a bearing. The support rod can rotate through the bearing. The output end of the hydraulic rod drives the L-shaped rod to move in different directions. Further, the rack drives the second gear to rotate in different directions. Further, the bracket rotates in different directions, so that the inclined plate is in different positions.

[0017] As a further improvement of the present invention: a bottom plate is fixedly arranged on one side of the base. A hydraulic rod is installed on one side of the bottom plate. The bottom plate supports the hydraulic rod, so that the hydraulic rod is installed on the base.

[0018] As a further improvement of the present invention: the output end of the hydraulic rod is fixedly provided with an L-shaped rod. One end of the L-shaped rod is fixedly arranged on one side of the rack. Turn on the external power switch of the hydraulic rod to control the output end of the hydraulic rod to drive the L-shaped rod to move in different directions.

[0019] As a further improvement of the present invention: A plurality of moving wheels are installed on one side of the base, an inclined plate is fixedly arranged on the inner wall of the bracket, and a handle is fixedly arranged on one side of the base. When using the conveying device, push the handle to move the whole device to the working ground through the plurality of moving wheels. The inclined plate is obliquely arranged on the inner wall of the bracket, and the coal conveyed by the conveyor belt slides down to the storage location through the inclined plate.

[0020] Compared with the prior art, the advantages and positive effects of the present invention are as follows.

[0021] 1. In the present invention, when conveying coal mines, pour the coal mines to be conveyed into the crushing box through the feed hopper. At this time, turn on the external power switch of the bidirectional motor. The output shaft of the bidirectional motor can rotate forward and backward. Control the output shaft of the bidirectional motor to drive one of the rotating rods to rotate clockwise, and further drive another first gear to rotate counterclockwise through one of the first gears, so that the other rotating rod rotates counterclockwise. At this time, the two crushing rollers rotate in opposite directions, and the two crushing rollers rotating in opposite directions squeeze and crush the coal. And when the other rotating rod rotates counterclockwise, it drives the second pulley to rotate counterclockwise, and drives the first pulley to rotate counterclockwise through the belt. Since there are two thread grooves with different helix directions on the outer surface of the bidirectional threaded rod, the two sleeves are connected to the thread grooves with different helix directions of the bidirectional threaded rod, and the pressing plate can slide on the inner wall of the crushing box. Therefore, when the bidirectional threaded rod rotates counterclockwise, the two sleeves move in opposite directions on the outer surface of the bidirectional threaded rod. When the bidirectional threaded rod rotates clockwise, the two sleeves move away from each other on the outer surface of the bidirectional threaded rod. At this time, the bidirectional threaded rod moves counterclockwise driven by the first pulley, so that the two sleeves move in opposite directions, and push the convex plate downward through the two transmission rods, further enabling the pressing plate to apply a downward pressure on the coal, making the coal contact the gap between the two crushing rollers faster, improving the coal crushing efficiency. After crushing, the coal falls through the discharge bin. At this time, control the output shaft of the bidirectional motor to rotate counterclockwise, so that the first pulley drives the bidirectional threaded rod to rotate clockwise, and the pressing plate moves upward. At this time, the next batch of coal can be crushed through the feed hopper. Thus, when conveying coal, the coal is crushed, improving the smoothness of coal conveying, reducing the friction during the conveying process, increasing the transportation speed and efficiency, and the coal crushing efficiency is relatively high.

[0022] 2. In the present invention, when transporting coal, the crushed coal falls onto the conveyor belt through the discharge bin, causing the conveyor belt to move horizontally for coal transportation. Multiple second telescopic rods can slide inside the inner walls of multiple first telescopic rods respectively. Multiple springs have elastic force. At this time, the elastic force of multiple springs squeezes multiple brushes, making the bristles of multiple brushes closely adhere to one side of the conveyor belt. At this time, turn on the external power switch of the drive motor. Two fixed rods support the drive motor, enabling the drive motor to be installed on the bracket. Furthermore, the output shaft of the drive motor drives the round rod to rotate counterclockwise, and further drives multiple brushes to rotate counterclockwise through multiple first telescopic rods and multiple second telescopic rods. The brushes rotating counterclockwise come into contact with the conveyor belt rotating clockwise to clean the conveyor belt, preventing coal powder from accumulating on the conveyor belt, ensuring the smooth operation of coal transportation, reducing blockage problems. By rotating the multiple screws on the baffle, the baffle can be removed from the bracket, and multiple brushes can be replaced and the inside of the bracket can be cleaned. Thus, when transporting coal, there is no need for manual cleaning of the conveyor belt, preventing coal powder from accumulating on the conveyor belt and improving the coal transportation efficiency.

[0023] 3. In the present invention, when using the conveying device, push the handle to move the entire device to the working ground through multiple moving wheels. When it is necessary to adjust the orientation of coal transportation, turn on the external power switch of the hydraulic rod. The support rod can rotate through the bearing. The bottom plate supports the hydraulic rod, enabling the hydraulic rod to be installed on the base. Control the output end of the hydraulic rod to drive the L-shaped rod to move in different directions, further causing the rack to drive the second gear to rotate in different directions, and further causing the bracket to rotate in different directions. The inclined plate is inclined and arranged inside the inner wall of the bracket. The coal transported by the conveyor belt slides down through the inclined plate. When the bracket rotates, the inclined plate can be in different orientations, and further the angle of coal transportation can be adjusted. Thus, when using the conveying device, the orientation of coal transportation can be adjusted without moving the entire device, improving the convenience of coal transportation.

However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0035] Please refer to Figures 1 to 8, this embodiment provides a conveyor for coal mine exploitation, including a bracket 1; a crushing box 2, fixedly arranged on one side of the bracket 1, and two rotating rods 201 are arranged on both sides of the inner wall of the crushing box 2 through bearings; two first gears 203, respectively fixedly sleeved on the outer surfaces of the two rotating rods 201, and the outer surfaces of the two first gears 203 are meshed with each other; a bidirectional threaded rod 207, arranged on the inner walls of both sides of the crushing box 2 through bearings, and two sleeves 208 are threadedly sleeved on the outer surface of the bidirectional threaded rod 207; two transmission rods 209, respectively movably arranged in the inner walls of the two sleeves 208, and a convex plate 210 is movably arranged on one side of the two transmission rods 209. Crushing rollers 202 are fixedly sleeved on the outer surfaces of the two rotating rods 201. A bidirectional motor 204 is installed on one side of the crushing box 2, and the output shaft of the bidirectional motor 204 is connected to one side of one of the rotating rods 201. A feed hopper 205 is fixedly arranged on one side of the crushing box 2, and a discharge bin 206 is fixedly arranged on the side of the crushing box 2 close to the bracket 1. A first pulley 212 is fixedly arranged on one side of the convex plate 210. A second pulley 214 is fixedly sleeved on the outer surface of the other rotating rod 201. A belt 213 is arranged on the outer surface of the second pulley 214, and a first pulley 212 is arranged on the inner wall of the belt 213. The first pulley 212 is fixedly sleeved on the outer surface of the bidirectional threaded rod 207.

[0036] During use, coal to be transported is poured into the interior of the crushing box 2 through the feed hopper 205. At this time, the external power switch of the bidirectional motor 204 is turned on. The output shaft of the bidirectional motor 204 can rotate forward and backward. Control the output shaft of the bidirectional motor 204 to drive one of the rotating rods 201 to rotate clockwise. Further, drive the other first gear 203 to rotate counterclockwise through one of the first gears 203, so that the other rotating rod 201 rotates counterclockwise. Then, the two crushing rollers 202 rotate in opposite directions. At this time, the two crushing rollers 202 rotating in opposite directions crush the coal by extrusion. And when the other rotating rod 201 rotates counterclockwise, it drives the second pulley 214 to rotate counterclockwise, and drives the first pulley 212 to rotate counterclockwise through the belt 213. Since there are two thread grooves with different helix directions on the outer surface of the bidirectional threaded rod 207, the two sleeves 208 are connected to the thread grooves with different helix directions of the bidirectional threaded rod 207, and the pressing plate 211 can slide on the inner wall of the crushing box 2. Then, when the bidirectional threaded rod 207 rotates counterclockwise, the two sleeves 208 move in opposite directions on the outer surface of the bidirectional threaded rod 207. When the bidirectional threaded rod 207 rotates clockwise, the two sleeves 208 move in opposite directions on the outer surface of the bidirectional threaded rod 207. At this time, the bidirectional threaded rod 207 moves counterclockwise under the drive of the first pulley 212, so that the two sleeves 208 move in opposite directions, and push the convex plate 210 downward through the two transmission rods 209. Further, the pressing plate 211 applies a downward pressure to the coal, so that the coal and the gap between the two crushing rollers 202 are in contact faster, improving the efficiency of coal crushing. After crushing, the coal falls through the discharge bin 206. At this time, control the output shaft of the bidirectional motor 204 to rotate counterclockwise, so that the first pulley 212 drives the bidirectional threaded rod 207 to rotate clockwise, and the pressing plate 211 moves upward. At this time, the next batch of coal can be crushed through the feed hopper 205.

[0037] Please refer to Figures 1 to 8 , in one embodiment, a conveyor belt 3 is provided on the inner wall of the bracket 1. Both sides of the inner wall of the bracket 1 are provided with round rods 301 through bearings. A plurality of first telescopic rods 302 are fixedly arranged on the outer surface of the round rod 301. The round rod 301 can rotate through the bearing. When the round rod 301 rotates, it drives the plurality of first telescopic rods 302 to rotate.

[0038] Please refer to Figures 1 to 8 , in one embodiment, a second telescopic rod 303 is movably embedded in the inner wall of each of the plurality of first telescopic rods 302. A spring 304 is movably sleeved on the outer surface of each of the plurality of second telescopic rods 303. The plurality of second telescopic rods 303 can slide in the inner walls of the plurality of first telescopic rods 302 respectively. The plurality of springs 304 have elasticity. At this time, the elasticity of the plurality of springs 304 presses the plurality of brush hairs 305, so that the brush hairs of the plurality of brush hairs 305 are closely attached to one side of the conveyor belt 3.

[0039] Please refer to Figures 1 to 8 , in one embodiment, multiple second telescopic rods 303 are grouped in pairs. A brush 305 is fixedly arranged on one side of each of the multiple second telescopic rods 303. Two fixing rods 307 are fixedly arranged on one side of the bracket 1.

A baffle 308 is arranged on one side of the bracket 1 by screws. The bristles of the multiple brushes 305 are closely attached to one side of the conveyor belt 3. At this time, turn on the external power switch of the driving motor 306. The two fixing rods 307 support the driving motor 306, so that the driving motor 306 is installed on the bracket 1. Furthermore, the output shaft of the driving motor 306 drives the round rod 301 to rotate counterclockwise. Further, through the multiple first telescopic rods 302 and the multiple second telescopic rods 303, the multiple brushes 305 are driven to rotate counterclockwise. The counterclockwise rotating brushes 305 come into contact with the clockwise rotating conveyor belt 3 to clean the conveyor belt 3 and prevent coal powder from accumulating on the conveyor belt 3. By turning the multiple screws on the baffle 308, the baffle 308 can be removed from the bracket 1 to replace the multiple brushes 305 and clean the inside of the bracket 1.

[0040] Please refer to Figures 1 to 8 , in one embodiment, a support rod 4 is fixedly arranged at the center of one side of the bracket 1. A second gear 401 is fixedly sleeved on the outer surface of the support rod 4. A rack 406 is meshed on the outer surface of the second gear 401. The second gear 401 is provided with a base 407 through a bearing. The support rod 4 can rotate through the bearing. The output end of the hydraulic rod 404 drives the L-shaped rod 405 to move in different directions. Further, the rack 406 drives the second gear 401 to rotate in different directions. Further, the bracket 1 rotates in different directions, so that the inclined plate 409 is in different positions.

[0041] Please refer to Figures 1 to 8 , in one embodiment, a bottom plate 403 is fixedly arranged on one side of the base 407. A hydraulic rod 404 is installed on one side of the bottom plate 403. The bottom plate 403 supports the hydraulic rod 404, so that the hydraulic rod 404 is installed on the base 407.

[0042] Please refer to Figures 1 to 8 , in one embodiment, a plurality of moving wheels 408 are installed on one side of the base 407. An inclined plate 409 is fixedly arranged at the inner wall of the bracket 1. A handle 410 is fixedly arranged on one side of the base 407. When using the conveying device, push the handle 410 to move the whole device to the use ground through the plurality of moving wheels 408. The inclined plate 409 is inclined and arranged at the inner wall of the bracket 1. The coal conveyed by the conveyor belt 3 slides down through the inclined plate 409 to the storage location.

[0043] Working principle: When transporting coal mines, the coal mines to be transported are poured into the inside of the crushing box 2 through the feeding hopper 205. At this time, the external power switch of the bidirectional motor 204 is turned on. The output shaft of the bidirectional motor 204 can rotate forward and backward. Control the output shaft of the bidirectional motor 204 to drive one of the rotating rods 201 to rotate clockwise, and further drive the other first gear 203 to rotate counterclockwise through one of the first gears 203, so that the other rotating rod 201 rotates counterclockwise. Then, the two crushing rollers 202 rotate in opposite directions. At this time, the two crushing rollers 202 rotating in opposite directions squeeze and crush the coal. And when the other rotating rod 201 rotates counterclockwise, it drives the second pulley 214 to rotate counterclockwise, and drives the first pulley 212 to rotate counterclockwise through the belt 213. Since there are two thread grooves with different helix directions on the outer surface of the bidirectional threaded rod 207, the two sleeves 208 are connected to the thread grooves with different helix directions of the bidirectional threaded rod 207, and the pressing plate 211 can slide on the inner wall of the crushing box 2. Therefore, when the bidirectional threaded rod 207 rotates counterclockwise, the two sleeves 208 move in opposite directions on the outer surface of the bidirectional threaded rod 207. When the bidirectional threaded rod 207 rotates clockwise, the two sleeves 208 move away from each other on the outer surface of the bidirectional threaded rod 207. At this time, the bidirectional threaded rod 207 moves counterclockwise driven by the first pulley 212, so that the two sleeves 208 move in opposite directions, and push the convex plate 210 downward through the two transmission rods 209. Further, the pressing plate 211 applies a downward pressure on the coal, so that the coal and the gap between the two crushing rollers 202 come into contact faster, improving the coal crushing efficiency. The crushed coal falls through the discharge bin 206. At this time, control the output shaft of the bidirectional motor 204 to rotate counterclockwise, so that the first pulley 212 drives the bidirectional threaded rod 207 to rotate clockwise, and the pressing plate 211 moves upward. At this time, the next batch of coal can be crushed through the feeding hopper 205. Thus, when transporting coal, the coal is crushed, improving the smoothness of coal transportation, reducing the friction during transportation, and increasing the transportation speed and efficiency. And the coal crushing efficiency is relatively high;

[0044] When transporting coal, the crushed coal falls onto the conveyor belt 3 through the discharge bin 206, causing the conveyor belt 3 to move horizontally to transport the coal. A plurality of second telescopic rods 303 can slide inside the inner walls of a plurality of first telescopic rods 302 respectively. A plurality of springs 304 have elastic forces. At this time, the elastic forces of the plurality of springs 304 squeeze a plurality of brushes 305, causing the bristles of the plurality of brushes 305 to closely adhere to one side of the conveyor belt 3. At this time, turn on the external power switch of the drive motor 306. The two fixing rods 307 support the drive motor 306, enabling the drive motor 306 to be installed on the bracket 1. Furthermore, the output shaft of the drive motor 306 drives the round rod 301 to rotate counterclockwise, and further drives a plurality of brushes 305 to rotate counterclockwise through a plurality of first telescopic rods 302 and a plurality of second telescopic rods 303. The counterclockwise rotating brushes 305 come into contact with the clockwise rotating conveyor belt 3 to clean the conveyor belt 3, prevent coal powder from accumulating on the conveyor belt 3, ensure the smooth operation of coal transportation, reduce blockage problems. By turning the screws on the rotating baffle 308, the baffle 308 can be removed from the bracket 1, and a plurality of brushes 305 can be replaced and the inside of the bracket 1 can be cleaned. Thus, when transporting coal, there is no need for manual cleaning of the conveyor belt 3, preventing coal powder from accumulating on the conveyor belt 3 and improving the coal transportation efficiency;

[0045] When using the conveying device, pushing the handle 410 causes the entire device to move to the working ground through a plurality of moving wheels 408. When it is necessary to adjust the orientation of coal transportation, turn on the external power switch of the hydraulic rod 404. The support rod 4 can rotate through a bearing. The bottom plate 403 supports the hydraulic rod 404, enabling the hydraulic rod 404 to be installed on the base 407. Control the output end of the hydraulic rod 404 to drive the L-shaped rod 405 to move in different directions, further causing the rack 406 to drive the second gear 401 to rotate in different directions, and further causing the bracket 1 to rotate in different directions. The inclined plate 409 is inclined and arranged inside the bracket 1. The coal transported by the conveyor belt 3 slides down through the inclined plate 409. When the bracket 1 rotates, the inclined plate 409 can be in different orientations, and further the angle of coal transportation can be adjusted. Thus, when using the conveying device, the orientation of coal transportation can be adjusted without moving the entire device, improving the convenience of coal transportation.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
