Description

Technical Field

[0001] The utility model relates to the technical field of coal mine conveyor belt conveyors, in particular to a buffer device for an electromechanical conveyor belt conveyor in an underground coal mine. Background Art

[0002] During the coal mining process, coal is often transported by conveyors. The most common conveyor is a belt conveyor. The main structure of the belt conveyor includes a transmission belt, a driving roller that drives the transmission belt, and a support roller that supports the transmission belt. The driving roller and the support roller that supports the transmission belt are installed on the conveyor frame.

[0003] In real life, since there is often a certain height gap between the unloaded coal and the conveyor belt, the coal will exert a large impact force on the conveyor belt during the unloading process. In the long run, it will cause great damage to the conveyor belt and affect the normal service life of the conveyor belt. Therefore, we proposed a buffer device for underground coal mine electromechanical conveyor belt to solve the above problem. Utility Model Content

[0009] Preferably, the first transmission mechanism includes a sprocket and a chain, and a sprocket is fixedly installed at one end of the corresponding first rotating rod, second rotating rod and third rotating rod, and the same chain is meshed and installed between the three sprockets.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Reference Figure 1-4 , a buffer device of an underground coal mine electromechanical conveyor belt conveyor, including a conveyor belt body 1, two first rotating rods 2 are rotatably installed on the conveyor belt body 1, rollers 3 are fixedly installed on the two first rotating rods 2, and the same conveyor belt 4 is sleeved on the two rollers 3, and a buffer box 5 is fixedly installed on the top side of the conveyor belt body 1, and a buffer chamber 6, a discharge chute 7 and a discharge port 8 are sequentially opened in the buffer box 5, and two second rotating rods 9 are rotatably installed on the inner wall of the buffer chamber 6, and flip paddles 10 are fixedly installed on the two second rotating rods 9. A third rotating rod 11 is rotatably installed on the inner wall of the discharge chute 7, and a conveying and unloading mechanism for the discharge chute 7 is provided on the third rotating rod 11. The corresponding first rotating rod 2, second rotating rod 9 and third rotating rod 11 are connected by a first transmission mechanism, and the two second rotating rods 9 are connected by a second transmission mechanism.

[0021] Furthermore, the blades on the two flipping paddles 10 are arranged in a staggered distribution, and the coal material being fed is flipped and buffered by the two flipping paddles 10 rotating in opposite directions.

[0022] Furthermore, the conveying and unloading mechanism includes a first auger 12 and a second auger 13, and the first auger 12 and the second auger 13 are fixedly installed on the third rotating rod 11 respectively. The external contact surfaces of the first auger 12 and the second auger 13 rotate and fit on the inner wall of the unloading trough 7, and the rotation directions of the first auger 12 and the second auger 13 are opposite; since the rotation directions of the first auger 12 and the second auger 13 are opposite, the coal material falling into the unloading trough 7 is synchronously moved toward the center point of the unloading port 8, so that the coal material falls smoothly on the conveyor belt 4 below.

[0023] Specifically, the first transmission mechanism includes a sprocket 14 and a chain 15. The corresponding first rotating rod 2, the second rotating rod 9 and the third rotating rod 11 are all fixedly installed with a sprocket 14 at one end, and the same chain 15 is meshed and installed between the three sprockets 14. Under the transmission action of the chain 15, the sprocket 14 and the first gear 16 on the corresponding second rotating rod 9, and the sprocket 14, the first auger 12 and the second auger 13 on the third rotating rod 11 are synchronously driven to rotate.

[0024] Specifically, the second transmission mechanism includes a first gear 16 and a second gear 17. The first gear 16 and the second gear 17 are fixedly mounted on the two second rotating rods 9, and the first gear 16 and the second gear 17 are engaged with each other. Since the first gear 16 is engaged with the second gear 17, the two flipping paddles 10 are synchronously driven to rotate in opposite directions in the buffer chamber 6 on the buffer box 5, and the coal being discharged is flipped and buffered by the two flipping paddles 10 rotating in opposite directions.

[0025] Furthermore, a motor 18 is fixedly installed on one side of the conveyor belt body 1, and the output shaft of the motor 18 is fixedly installed on one end of the corresponding first rotating rod 2; by starting the motor 18, the roller 3 and sprocket 14 on the corresponding first rotating rod 2 can be driven to rotate.

[0026] During use: During the unloading process of coal, by starting the motor 18, the roller 3 and the sprocket 14 on the corresponding first rotating rod 2 are driven to rotate, thereby driving the conveyor belt 4 to convey and rotate. At the same time, under the transmission action of the chain 15, the sprocket 14 and the first gear 16 on the corresponding second rotating rod 9 are synchronously driven to rotate, and the sprocket 14, the first auger 12 and the second auger 13 on the third rotating rod 11 are rotated. Since the first gear 16 is meshed with the second gear 17, the two flipping paddles 10 are synchronously driven to rotate on the buffer box 5. The flushing chamber 6 rotates in opposite directions, and the two oppositely rotating flip paddles 10 are used to flip and buffer the unloaded coal, so that the unloaded coal is separated and enters the discharge chute 7. Since the rotation directions of the first auger 12 and the second auger 13 are opposite, the coal dropped into the discharge chute 7 is synchronously moved toward the center point of the discharge port 8, so that the coal falls smoothly on the conveyor belt 4 below, reducing the impact force on the conveyor belt 4 during the unloading process of the coal, reducing damage to the conveyor belt 4, and ensuring the normal service life of the electromechanical transport belt conveyor in the underground coal mine.
