[0002] Mining belt conveyor is also called belt conveyor. The conveyor belt moves according to the friction transmission principle. It is suitable for conveying powdery, granular, small-block low-abrasive materials and bagged materials with a bulk density of less than 1.67 / ton / cubic meter, which are easy to take out, such as coal, gravel, sand, cement, fertilizer, grain, etc.

[0003] At present, the mining face of mines is affected by various structures. In order to avoid long-distance coal support or gangue breaking during tunnel excavation, after tunnel excavation, the local fluctuation amplitude exceeds the natural drooping amplitude of the belt conveyor. During mining, the belt conveyor is prone to large-scale shaking and coal spilling during operation. A large amount of spilled coal will bury the belt. The long-term friction of the belt conveyor may even cause a fire. The spilled coal is pulled into the head and tail of the machine, which may easily lead to belt breakage. In addition, the rolling effect of the small width of the belt pressing device is poor and the strength is insufficient. The width required for strength is large, and the belt is blocked and scattered seriously when it is running. The contradiction between belt pressing and blocking has not been effectively solved, and the belt conveyor has a high risk of operation. Therefore, the utility model proposes a new type of belt pressing device for mining belt conveyor to solve the above problems. Utility Model Content

The inner wall of the movable rod 5 is slidably connected to the outer wall of the connecting rod 2, and a limiting mechanism matching the movable rod 5 is provided on the inner side of the connecting rod 2, so that the belt is limited to the top of the tank road hanging ear 6 to avoid the risk of scratching the belt and tearing the belt, and the limiting mechanism flexibly adjusts the distance between the movable rod 5 and the connecting rod 2 according to the different distances between the belt conveyor and the tunnel roof, so that the practicality of the device is higher.

[0021] The top of the fixing rod 1 is provided with a No. 1 steel plate 3, and the bottom of the fixing rod 1 and the top of the connecting rod 2 are connected with a No. 2 steel plate 4. The No. 1 steel plate 3 and the No. 2 steel plate 4 are symmetrically provided with connecting holes on both sides, and the connecting holes on the No. 1 steel plate 3 are provided with anchor rods inside. The No. 1 steel plate 3 is fixedly connected to the external top plate through the anchor rods, and the connecting holes on the No. 2 steel plate 4 are provided with connecting bolts inside. The two ends of the connecting bolts are threaded with fixing nuts, and the two No. 2 steel plates 4 are detachably connected by connecting bolts and fixing nuts. The movable rod 5 is arranged at the bottom of the connecting rod 2, and the No. 2 steel plate 4 at the bottom of the fixing rod 1 is aligned with the No. 2 steel plate 4 at the top of the connecting rod 2 and placed together. At this time, the connecting holes in the two No. 2 steel plates 4 are aligned with each other, and the connecting bolts are inserted into the connecting holes. Then, the fixing nuts are screwed on both ends of the connecting bolts, and the two No. 2 steel plates 4 are clamped by using the fixing nuts, so that the fixing rod 1 and the connecting rod 2 are connected together, and they are fixed to the top plate with the anchor rods for use, which is convenient for installation and removal.

[0022] The limiting mechanism includes a bracket 9, a limiting pin 10, a spring 11, a rotating shaft 12 and a rotating handle 13. The bracket 9 is fixed to one side of the bottom of the connecting rod 2, and the limiting pin 10 is inserted into the inside of the bracket 9. A plurality of limiting holes 8 are equidistantly arranged on one side of the movable rod 5. One end of the limiting pin 10 passes through the inside of the connecting rod 2 and extends to the inside of the limiting hole 8. The other end of the limiting hole 8 is hinged with a rotating handle 13 through the rotating shaft 12. The outer side of the limiting pin 10 is sleeved with a spring 11. When the rotating handle 13 is rotated outward, the limiting pin 10 and the movable rod 5 are locked. The turning handle 13 is hinged, and the bracket 9 limits the limit pin 10, so the limit pin 10 can also be pulled to move outward, and one end of the limit pin 10 withdraws from the interior of the limit hole 8, so that it no longer limits the movable rod 5.

[0023] A slide groove 7 is provided on the other side of the movable rod 5, and a threaded rod 14 is connected to the bottom of the connecting rod 2. One end of the threaded rod 14 passes through the interior of the threaded rod 14 and is threadedly connected to an adjusting nut. After the limit mechanism releases the restriction, the movable rod 5 will not immediately move downward due to gravity. At this time, the adjusting nut at one end of the threaded rod 14 is loosened so that it no longer clamps the movable rod 5. The movable rod 5 can adjust the distance downward at the bottom of the connecting rod 2 to avoid the release of the restriction of the limit mechanism, which causes the movable rod 5 to suddenly move downward and collide violently with the bottom of the connecting rod 2 and be damaged.

Insert the fastening bolt 21 into the inside of the socket 22 and twist it to rotate, so that one end of the fastening bolt 21 passes through the socket 22 and enters the inside of the threaded hole 19 and is connected with the fixing plate 18, and the tank channel hanging ear 6 is fixed to the fixing plate 18 together, and the tank channel hanging ear 6 is installed on one side of the bottom of the movable rod 5. The interior of the fixing plate 18 is provided with a bearing 17 to reduce the friction between the connecting shaft 16 and the fixing plate 18, so that the tank channel hanging ear 6 can rotate at the bottom of the movable rod 5.

[0025] The belt pressing device of the mining belt conveyor rotates the handle 13 outward. Since the limit pin 10 is hinged to the handle 13 and the bracket 9 limits the limit pin 10, the limit pin 10 can also be pulled to move outward. One end of the limit pin 10 withdraws from the interior of the limit hole 8, so that it no longer limits the movable rod 5. At this time, people can adjust the downward movement distance of the movable rod 5 according to the different distances between the belt conveyor and the tunnel roof, and limit the belt at the top of the tank road hanging ear 6 to avoid the risks of scratching the belt and tearing the belt. The limiting mechanism flexibly adjusts the distance between the movable rod 5 and the connecting rod 2 according to the different distances between the belt conveyor and the tunnel roof, making the device more practical. After that, let go and use the elastic force generated by the compression of the spring 11 to drive the limit pin 10 to reset, and re-enter the adjacent limit hole 8 to continue to limit the movable rod 5, so that the belt pressing device can adapt to the complex environment inside the mine.
