Description

Technical Field

[0001] The utility model relates to the technical field of mining, in particular to a device for transporting waste rock in mining. Background Technique

[0002] During the production of a mine, it is necessary to lift the waste rock in the mine to the surface. The waste rock in the middle section of the mine is directly lifted to the surface through the main shaft, while the waste rock below the middle section is first lifted to the middle section through a blind vertical shaft, then distributed to the waste rock chute through a distribution trolley, and then transported to the chute of the main shaft at the unloading station by a mine car and lifted to the surface after being crushed. The transportation process is cumbersome, the production is discontinuous, time-consuming and laborious. Therefore, it is necessary to install a belt conveyor device from below the ore discharge machine of the waste rock chute to the waste rock unloading station, so as to directly transport the waste rock to the surface. At present, when using a belt conveyor device to transport waste rock, it is quite common that the belt conveyor device is unstable in transporting waste rock, and the waste rock is easy to slide on the conveyor belt, thus causing serious safety hazards. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a device for transporting waste rock in mining, so as to solve the problems put forward in the above background technique.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a device for transporting waste rock in mining, including a belt conveyor. Both the front and rear sides of the upper end of the belt conveyor are fixed with side plates. The upper ends of the side plates are fixed with a support frame. A rotating shaft is rotatably connected between the support frames. A concave frame is fixed on the surface of the rotating shaft. One end inside the concave frame is fixed with a push plate. A transmission mechanism is installed at the rear end of the rear support frame. The transmission mechanism is connected to the rotating shaft.

Detailed implementation

[0016] As Figures 1 to 3 shown, a device for transporting waste rock in mining industry includes a belt conveyor 1. On both the front and rear sides of the upper end of the belt conveyor 1, side plates 3 are fixed. On the upper end of the side plates 3, a support frame 4 is fixed. Between the support frames 4, a rotating shaft 6 is rotatably connected. On the surface of the rotating shaft 6, a concave frame 7 is fixed. At one end inside the concave frame 7, a push plate 8 is fixed. At the rear end of the rear support frame 4, a transmission mechanism 5 is installed. The transmission mechanism 5 is connected to the rotating shaft 6. On the right side of the rear end of the belt conveyor 1, a driving mechanism 2 is installed. The driving mechanism 2 is in transmission connection with the transmission mechanism 5. The driving mechanism 2 includes a motor housing 21, a motor 22, a first horizontal shaft 23, a second horizontal shaft 24, and a first synchronous belt 25. The motor housing 21 is fixed to the belt conveyor 1. The motor 22 is fixedly installed on the upper end of the motor housing 21. The output end of the motor 22 is connected to a motor shaft 221. The lower part of the motor shaft 221 penetrates into the interior of the motor housing 21 and is in bearing connection with the motor housing 21. In the middle of the outside of the motor shaft 221, a driving bevel gear 223 is fixed. The first horizontal shaft 23 is located in front of the driving bevel gear 223. On the outside of the first horizontal shaft 23, a first bearing block 231 is installed. The bottom of the first bearing block 231 is fixed to the motor housing 21. At the rear part of the first horizontal shaft 23, a driven bevel gear 232 is fixed. The front part of the first horizontal shaft 23 is fixed to the belt roller of the belt conveyor 1. The driving bevel gear 223 is in meshing connection with the driven bevel gear 232. When the motor 22 drives the motor shaft 221 to rotate, the motor shaft 221 will drive the driving bevel gear 223 to rotate. Through the meshing of the driving bevel gear 223 and the driven bevel gear 232, the driven bevel gear 232 drives the first horizontal shaft 23 to rotate. At this time, the first horizontal shaft 23 drives the belt roller of the belt conveyor 1 to rotate, so as to make the belt of the belt conveyor 1 actively transport the waste rock in mining industry;

[0017] A worm 222 is fixed outside the motor shaft 221 and above the driving bevel gear 223. The second horizontal shaft 24 is located on the left side of the worm 222. The rear end of the second horizontal shaft 24 is connected to the bearing at the rear end inside the motor housing 21. A second bearing seat 243 is installed on the front outer part of the second horizontal shaft 24. The upper end of the second bearing seat 243 is fixed to the motor housing 21. A worm gear 241 is fixed to the outer rear side of the second horizontal shaft 24. The worm 222 is in transmission connection with the worm gear 241. When the motor shaft 221 drives the driving bevel gear 223 to rotate, it can also drive the worm 222 to rotate. Through the transmission between the worm 222 and the worm gear 241, the worm gear 241 drives the second horizontal shaft 24 to rotate. There is a self-locking property between the worm 222 and the worm gear 241. In this way, when the motor 22 is not started, the worm gear 241 will not rotate in the reverse direction;

[0018] A first driving synchronous pulley 242 is fixed outside the second horizontal shaft 24 and in front of the worm gear 241. The first synchronous belt 25 is installed outside the first driving synchronous pulley 242. A first window 26 is opened at the left end of the motor housing 21. The other end of the first synchronous belt 25 extends out of the first window 26. The transmission mechanism 5 includes a protective housing 51, an upper shaft rod 52, a second driven synchronous pulley 53, a lower shaft rod 54, a second driving synchronous pulley 55, a first driven synchronous pulley 56, and a second synchronous belt 58. The protective housing 51 is fixed to the support frame 4. The lower shaft rod 54 is connected to the bearing in the lower part inside the protective housing 51. The first driven synchronous pulley 56 is fixed to the outside of the lower shaft rod 54. A second window 57 is opened at one end of the protective housing 51 close to the motor housing 21. The other end of the first synchronous belt 25 extends into the second window 57 and is connected to the first driven synchronous pulley 56. When the second horizontal shaft 24 rotates, it can drive the first driving synchronous pulley 242 to rotate. At this time, the first driving synchronous pulley 242 drives the first driven synchronous pulley 56 to rotate through the first synchronous belt 25, and the first driven synchronous pulley 56 will drive the lower shaft rod 54 to rotate;

[0019] The second driving synchronous pulley 55 is located on one side of the first driven synchronous pulley 56 and is fixed outside the lower shaft rod 54. The upper shaft rod 52 is connected by bearings to the upper part inside the protective housing 51. The second driven synchronous pulley 53 is fixed outside the upper shaft rod 52. The second synchronous belt 58 is connected between the second driving synchronous pulley 55 and the second driven synchronous pulley 53. The front end of the upper shaft rod 52 is fixed to the rotating shaft 6. When the lower shaft rod 54 rotates, it can drive the second driving synchronous pulley 55 to rotate. Since the second driving synchronous pulley 55 and the second driven synchronous pulley 53 are synchronously driven by the second synchronous belt 58, the second driven synchronous pulley 53 can drive the upper shaft rod 52 to rotate, and the upper shaft rod 52 will drive the rotating shaft 6 to rotate. The rotating shaft 6 drives the concave frame 7 to perform a circular motion. When the concave frame 7 rotates from the upper part to the lower part, the push plate 8 can push the waste rock on the belt conveyor 1, so that even if the waste rock slides down, it will be pushed back to the upper part by the push plate 8, and there is a side plate 3 on the side to block the waste rock to prevent the waste rock from falling from the side, thereby ensuring the improvement of safety and avoiding serious safety hazards;

[0020] A rubber strip 9 is fixed to the other end of the concave frame 7. By arranging the rubber strip 9 at the other end of the concave frame 7, when the other end of the concave frame 7 rotates to contact the belt of the belt conveyor 1, it can prevent the other end of the concave frame 7 from cutting the belt of the belt conveyor 1 due to sharpness, and improves the service life of the belt conveyor 1.
