Coal mining methods are divided into open-pit mining and underground mining. Mechanized methods are usually used, and special transportation transmission devices are required during the transportation of coal.

The device drives the crawler belt to rotate through a traditional transmission wheel. During the coal mining process, large and small gravel may fall into the inside of the crawler belt. When the gravel rolls between the gear and the crawler belt, it will jam the discharge material and the crawler belt, causing the equipment to stop operating or damage the internal structure of the device.

[0004] To this end, the present application designs a transport transmission device to solve the above problems. Utility Model Content

[0024] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in a variety of different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0026] Figures 1-6 This is a specific embodiment of the present invention, which is a transport transmission device. One side of a first annular side plate 1 is rotatably connected to a transmission rod 3 via a first rotating shaft 2. One end of the transmission rod 3 is rotatably connected to a second annular side plate 5 via a second rotating shaft 4. A snap plate 6 is fixedly connected to one side of the inner wall of each of the first and second annular side plates 1 and 5. A transmission belt 7 is overlapped on the surface of the snap plate 6. The transmission rod 3 is rollably connected to the outer surface of the transmission belt 7. A conveyor belt 8 is overlapped on one side of the opposing surface of the first and second annular side plates 1 and 5. The transmission rod 3 is rollably connected to the inner surface of the conveyor belt 8.

[0027] When in use, through the arrangement of the first annular side plate 1, the transmission rotating rod 3, the second annular side plate 5, the snap plate 6, the transmission belt 7 and the conveyor belt 8, there are multiple groups of transmission rotating rods 3, and they are all distributed on the opposite side of the first annular side plate 1 and the second annular side plate 5 to form a ring shape. The opposite sides of the first annular side plate 1 and the second annular side plate 5 are in contact with the two sides of the conveyor belt 8 and overlap the outer annular surfaces of the multiple groups of transmission rotating rods 3. The inner walls of the first annular side plate 1 and the second annular side plate 5 are connected with the snap plate 6. The transmission belt 7 is overlapped on the outer surface of the snap plate 6 and is in an annular shape. The transmission belt 7 is in contact with the inner annular surfaces of the multiple groups of transmission rotating rods 3. When the transmission belt 7 rotates and slides, it drives the transmission rotating rod 3 to rotate, and the transmission rotating rod 3 drives the conveyor belt 8 to rotate and slide. Since the first annular side plate 1 and the second annular side plate 5 are attached to both sides of the conveyor belt 8, the snap plate 6 is fitted to both sides of the transmission belt 7, so that a closed hollow annular space is formed between the transmission belt 7 and the conveyor belt 8, and the transmission rotating rod 3 between the transmission belt 7 and the conveyor belt 8 is not in contact with the outside world. General transportation devices are roughly divided into two types of transmission methods: crawler type and roller type. The transportation devices required for mining are mostly rubber crawler type, which can reduce the leakage of materials. The general crawler type conveyor device requires rollers for transmission and limiting. During the use of the device, a large amount of crushed stone and other mineral materials will fall into the interior of the crawler. When the crushed stone rolls between the crawler and the roller, it may get stuck in the roller, causing the equipment to stop operating or causing certain damage to the internal structure of the device. The device can put the transmission rotating rod 3 in a closed environment, prevent the crushed material from falling between the transmission mechanism and the crawler, greatly improve the operation stability of the device, and extend the service life of the device.

[0028] See also Figure 1 and Figures 3 to 6 The first annular side plate 1 and the second annular side plate 5 are fixedly connected to the load-bearing columns 9 on both sides of the bottom. The first annular side plate 1 and the second annular side plate 5 are fixedly connected to the connecting support rod 10 in the middle. A limited slide groove 11 is provided on one side of the connecting support rod 10. A support frame 12 is slidably connected to one side of the connecting support rod 10. Both ends of the support frame 12 are fixedly connected to a limited slider 13. The limit slider 13 is slidably connected to the inside of the limit slide groove 11. The bottom of the limit slider 13 is fixedly connected to a supporting spring 14. A limited telescopic rod 15 is provided in the middle of the support spring 14. The bottom of the support spring 14 is fixedly connected to the inner bottom wall of the limit slide groove 11. A programmable motor 16 is installed in the middle of the upper surface of the support frame 12. The output end of the programmable motor 16 is rotatably connected to a transmission gear 17 through a load-bearing shaft. The inner wall of the transmission belt 7 is fixedly connected to a rubber gear ring 18, which meshes with the rubber gear ring 18.

[0029] When in use, through the setting of the limiting slide 11, the limiting slider 13, the supporting spring 14, the programmable motor 16, the transmission gear 17 and the rubber gear ring 18, the support frame 12 can slide up and down on one side of the support rod 10 through the limiting slide 11 and the limiting slider 13. Under the action of no external force, the limiting slider 13 is pushed upward by the supporting spring 14 to drive the support frame 12 upward. When the limiting slider 13 is at the highest point in the limiting slide 11, the transmission gear 17 at the output end of the programmable motor 16 is engaged with the top of the inner ring of the rubber gear ring 18. When the programmable motor 16 is working, it drives the transmission gear 17 to rotate, and the transmission gear 17 drives the rubber gear ring 18 to rotate, and the rubber gear ring 18 drives the transmission belt 7 to rotate. During the operation, small mineral materials may be stuck in the bayonet of the rubber gear ring 18. When the rubber gear ring 18 with foreign matter rotates to the meshing position with the transmission gear 17, the foreign matter will exert a downward thrust on the transmission gear 17. At this time, the transmission gear 17 pushes the limit slider 13 downward a short distance through the programmable motor 16 and the support frame 12. The limit slider 13 exerts downward pressure on the support spring 14, causing the support spring 14 to be compressed and deformed. When the foreign matter rolls over the transmission gear 17, the support spring 14 rebounds, causing the transmission gear 17 to re-engage with the rubber gear ring 18, reducing the probability of structural damage caused by rigid collision of the internal structure of the equipment, improving the operating stability of the device, and extending the service life of the device.

[0030] Working principle:

[0031] When the device is used to transport mineral materials, the first annular side plate 1 and the second annular side plate 5 are attached to both sides of the conveyor belt 8, and the snap plate 6 is attached to both sides of the transmission belt 7, so that a closed hollow annular space is formed between the transmission belt 7 and the conveyor belt 8. The transmission rotating rod 3 between the transmission belt 7 and the conveyor belt 8 does not contact the outside world, preventing crushed materials from falling between the transmission mechanism and the crawler, thereby improving the operating stability of the device and extending the service life of the device. When small mineral materials are stuck in the bayonet of the rubber tooth ring 18, the transmission gear 17 will move downward a short distance when it contacts foreign objects through the compressive deformation of the support spring 14, so that the gear can run over the foreign objects. At the same time, the rebound of the support spring 14 can make the transmission gear 17 re-engage with the rubber tooth ring 18, reducing the probability of equipment shutdown or damage and extending the service life.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
