Technical Field
[0001] This utility model relates to the field of coal mining technology, specifically a coal mining backfilling and tunneling mechanism. Background Technology
[0002] Coal is a black or brown solid combustible mineral mainly formed by the long-term biochemical and physicochemical transformation of ancient plants under specific geological conditions. During its formation, a large amount of plant remains accumulate in suitable environments such as swamps, and are gradually formed through the decomposition and compaction by microorganisms. Currently, coal is usually mined using tunneling machines.
[0003] Existing tunneling machines lack protective devices at the top, causing debris to fall and damage them during mining operations due to vibrations. This reduces the machine's lifespan. Furthermore, mining operations generate significant amounts of dust that can be inhaled by workers, impacting their health. Therefore, we propose a coal mine backfilling tunneling mechanism. Utility Model Content
[0004] The purpose of this utility model is to provide a coal mine mining and backfilling tunneling mechanism to solve the problems mentioned in the background art. When existing tunneling machines are in use, the lack of protective devices on the top causes the crushed rocks on the top to fall and damage the tunneling machine during mining due to the vibration of the mine tunnel, thereby reducing the service life of the tunneling machine. In addition, a large amount of dust is generated during mining and dispersed in the air, which can affect the health of workers if inhaled.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a coal mine mining backfilling tunneling mechanism, comprising a tunneling machine body, a plate, and a dust suppression box. The dust suppression box is fixedly connected to the lower side of the right side wall of the tunneling machine body. The plate is fixedly connected to the top of the tunneling machine body. A rubber airbag is fixedly connected to the top of the plate. A protective top plate is fixedly connected to the top of the rubber airbag. An installation groove is formed at the middle of the top of the plate, inside the rubber airbag. A hollow column is fixedly connected to the bottom of the inner wall of the installation groove. The top left and right sides of the hollow column are connected to the left and right sides of the inner wall of the rubber airbag via flexible hoses. Springs are fixedly connected to the left and right sides of the inner wall of the hollow column. A piston is fixedly connected to the end of the spring. The outer side wall of the piston is slidably connected to the inner wall of the hollow column. A rubber sealing ring is provided between the outer side wall of the piston and the inner wall of the hollow column. Side plates are fixedly connected to the left and right side walls of the protective top plate.
[0006] As a further description of the above technical solution:
[0007] The protective top plate has a slope on both the front and rear sides, and a high-damping rubber layer is provided on the top of the protective top plate.
[0008] As a further description of the above technical solution:
[0009] A protective cover is fixedly connected to the bottom of the protective top plate and to the outside of the plate.
[0010] As a further description of the above technical solution:
[0011] A fan is fixedly connected to the top center of the dust collection box, and the air outlet of the fan is connected to the dust collection box. Exhaust hoods are fixedly connected to the left side of the front and rear side walls of the tunneling machine body. Two exhaust hoods are connected to the air inlet of the fan via pipes. A square ring pipe is fixedly connected to the upper side of the inner wall of the dust collection box, and the square ring pipes are evenly distributed from top to bottom. Every two square ring pipes are connected by a water pipe. Atomizing nozzles are evenly arranged around the inner side wall of the square ring pipe. A water pump is fixedly connected to the top rear side of the dust collection box, and the water outlet of the water pump is connected to the uppermost square ring pipe via a water pipe. A water tank is fixedly connected to the top of the dust collection box, between the fan and the water pump, and the water tank is connected to the water inlet of the water pump via a water pipe.
[0012] As a further description of the above technical solution:
[0013] A hollow block is fixedly connected to the top of the inner wall of the dust collection box and to the inside of the multiple square annular tubes. Ventilation holes are evenly opened on the outer wall of the hollow block.
[0014] As a further description of the above technical solution:
[0015] The inner wall of the exhaust hood is equipped with a baffle.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This coal mine mining and backfilling tunneling mechanism protects the tunneling machine body by blocking falling debris with a protective roof plate. The protective roof plate, in conjunction with rubber airbags, plates, mounting slots, hollow columns, springs, and pistons, buffers and dampens the falling debris, thereby reducing the impact of vibration on the tunneling machine body. The debris is then guided by side plates to slide down from both sides of the protective roof plate to both sides of the tunneling machine body, thus protecting the top of the tunneling machine body and preventing damage to the tunneling machine body from falling debris from the top of the mine tunnel during mining, thereby extending the service life of the tunneling machine body.
[0018] 2. The coal mine mining and backfilling tunneling mechanism uses a fan and exhaust hood to draw the dust generated during mining into a dust suppression box. Hollow blocks and ventilation holes are used to evenly distribute the drawn air throughout the dust suppression box to enhance the subsequent dust suppression effect. A water pump then draws water from the water tank into a square ring pipe, which is then atomized and sprayed out through atomizing nozzles to suppress dust in the air. This mechanism can suppress dust generated during mining, thus preventing it from being dispersed in the air and inhaled by workers. Attached Figure Description

[0029] This utility model provides a coal mine mining backfilling tunneling mechanism that can protect the tunneling machine body 100 from damage caused by falling rocks from the top of the mine tunnel during mining, thereby extending the service life of the tunneling machine body 100. It can also suppress dust generated during mining, preventing it from being dispersed into the air and inhaled by workers. Please refer to [link to relevant documentation]. Figure 1-6 It includes the tunneling machine body 100, the plate body 200, and the dust collection box 300;
[0030] Please refer to it again. Figure 1-4A rubber airbag 210 is fixedly connected to the top of the plate 200. The rubber airbag 210 is used to dampen the protective top plate 211 and absorb the vibration generated when rocks collide. The protective top plate 211 is fixedly connected to the top of the rubber airbag 210. The protective top plate 211 is used to protect the tunneling machine body 100. A mounting groove 212 is opened in the middle of the top of the plate 200 and inside the rubber airbag 210. The mounting groove 212 is used to install a hollow column 213. The hollow column 213 is fixedly connected to the bottom of the inner wall of the mounting groove 212. When the rubber airbag 210 collapses during the cushioning of rocks, the hollow column 213 temporarily releases the internal air into the hollow column 213, thereby achieving the purpose of cushioning. The top of the hollow column 213... The left and right sides are connected to the inner walls of the rubber airbag 210 via flexible hoses. Springs 214 are fixedly connected to the left and right sides of the inner wall of the hollow column 213. Springs 214 are used to drive the piston 215 to reset. The end of the spring 214 is fixedly connected to the piston 215, which is used to return the air discharged from the rubber airbag 210 after buffering. The outer wall of the piston 215 is slidably connected to the inner wall of the hollow column 213. A rubber sealing ring is provided between the outer wall of the piston 215 and the inner wall of the hollow column 213 to improve the sealing between the piston 215 and the hollow column 213. Side plates 216 are fixedly connected to the left and right side walls of the protective top plate 211. The side plates 216 are used to protect against stones. The guide allows rocks to slide down from both sides. The dust collection box 300 is fixedly connected to the lower right side wall of the tunneling machine body 100. The plate 200 is fixedly connected to the top of the tunneling machine body 100. The top and rear sides of the protective top plate 211 have slopes to facilitate rock sliding. The top of the protective top plate 211 has a high-damping rubber layer, which helps reduce rock rebound while assisting in shock absorption, and also protects the protective top plate 211, extending its service life. A protective cover 220 is fixedly connected to the bottom of the protective top plate 211, located on the outside of the plate 200. The protective cover 220 protects the rubber airbag 210, further extending the service life of the protective top plate 211. When rocks fall from the top of the mine tunnel, they fall and are protected... When the top plate 211 comes into contact with the rock, the protective top plate 211 moves downwards due to the impact of the rock, which squeezes the rubber airbag 210 and causes the rubber airbag 210 to collapse, releasing the internal gas into the hollow column 213. Under the action of the gas, the pistons 215 on both sides move outwards, which squeezes the spring 214 and causes the spring 214 to contract, buffering the rock and absorbing the vibration generated by the collision. At the same time, the high-damping rubber layer on the top of the protective top plate 211 assists in shock absorption and also reduces the rebound of the rock. Under the guidance of the side plate 216, the rock slides down the slope of the protective top plate 211 to both sides of the tunneling machine body 100. At the same time, the spring 214 rebounds and drives the piston 215 to reset. The piston 215 pushes the gas back into the rubber airbag 210 to restore the original state.
[0031] In summary, this method can protect the tunneling machine body 100, preventing damage to the tunneling machine body 100 from falling rocks from the top of the mine tunnel during mining, thereby extending the service life of the tunneling machine body 100.
[0032] Please refer to it again. Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 A fan 310 is fixedly connected to the top center of the dust collection box 300. The fan 310 is used to draw the generated dust into the dust collection box 300. The air outlet of the fan 310 is connected to the dust collection box 300. Exhaust hoods 311 are fixedly connected to the left side of the front and rear side walls of the tunneling machine body 100. The exhaust hoods 311 are used to guide airflow. The two exhaust hoods 311 are connected to the air inlet of the fan 310 through pipes. A square ring pipe 312 is fixedly connected to the upper side of the inner wall of the dust collection box 300. 12 is used to install atomizing nozzles 313, and the square ring tubes 312 are evenly distributed from top to bottom. Every two square ring tubes 312 are connected by a water pipe. Atomizing nozzles 313 are evenly arranged around the inner side wall of the square ring tubes 312. The atomizing nozzles 313 are used to atomize water for dust suppression. A water pump 314 is fixedly connected to the rear top of the dust suppression box 300. The water pump 314 is used to transport water. The outlet of the water pump 314 is connected to the uppermost square ring tube 312 by a water pipe. The top of the dust suppression box 300... A water tank 315 is fixedly connected between the fan 310 and the water pump 314. The water tank 315 is used to hold water, and the water tank 315 is connected to the water inlet of the water pump 314 through a water pipe. A hollow block 320 is fixedly connected to the top of the inner wall of the dust settling box 300 and inside multiple square ring pipes 312. The hollow block 320 is used to cooperate with the ventilation holes to evenly distribute air into the interior of the dust settling box 300 to improve the dust settling efficiency. Ventilation holes are evenly opened on the outer wall of the hollow block 320. The inner wall of the exhaust hood 311... The cavity wall is equipped with a baffle to prevent foreign objects from entering. The water pump 314 and the fan 310 are started by an external controller. The water pump 314 draws water from the water tank 315 and sends it into the square ring pipe 312, and then sprays the water atomized through the atomizing nozzle 313. The fan 310, in conjunction with the exhaust hood 311, draws the dust-containing air into the dust settling box 300. The air is evenly distributed to all parts of the dust settling box 300 through the hollow block 320 and the ventilation holes. The atomized water settles the dust in the air.
[0033] In summary, dust generated during mining can be suppressed, thus preventing it from being dispersed into the air and inhaled by workers.
[0034] In practical use, when personnel in this technical field are mining coal using the tunneling machine body 100, they start the water pump 314 and the blower 310 via an external controller. The water pump 314 draws water from the water tank 315 and sends it into the square ring pipe 312, then atomizes the water and sprays it out through the atomizing nozzle 313. The blower 310, in conjunction with the exhaust hood 311, draws dust-laden air into the dust collection box 300. The air is then evenly distributed throughout the dust collection box 300 via the hollow block 320 and ventilation holes. The atomized water suppresses dust in the air. During operation, when rocks fall from the top of the mine tunnel, they come into contact with the protective roof plate 211, which collects the rocks. The impact causes the rock to move downwards, squeezing the rubber airbag 210 and causing it to collapse, releasing the internal gas into the hollow column 213. Under the action of the gas, the pistons 215 on both sides move outwards, squeezing the spring 214 and causing it to contract, thus buffering the rock and absorbing the vibration generated by the collision. At the same time, the high-damping rubber layer on the top of the protective top plate 211 assists in shock absorption and also reduces the rebound of the rock. Guided by the side plate 216, the rock slides down the slope of the protective top plate 211 to both sides of the tunneling machine body 100. At the same time, the spring 214 rebounds, causing the piston 215 to reset, and the piston 215 pushes the gas back into the rubber airbag 210 to restore its original state.
