In the prior art, the dust reduction of roadway heading machine mainly relies on simple spraying device, these spraying devices usually adopt fixed-angle nozzles, water is delivered to the nozzle by water pump to form water mist to suppress dust, and the mechanical structure is relatively simple, mainly composed of water tank, water pump, pipeline and nozzle, the water pump extracts water from the water tank, and delivers water to the nozzle through the pipeline, and the nozzle sprays water to form water mist, in terms of technical principle, the dust is combined with water mist by using the adsorption and sedimentation of water, so as to reduce the dust concentration in the air. However, the existing roadway heading machine spraying device has the problem of inconvenient nozzle angle adjustment, since the nozzle angle is fixed, it is impossible to accurately spray at different angles according to the actual heading condition, the working position and angle of pick are constantly changed in the roadway heading process, and the dust generation area also changes, the fixed-angle nozzle is difficult to cover all dust generation areas, resulting in poor dust reduction effect, especially in some complex roadway environment, such as curved roadway, inclined roadway, etc., the fixed-angle nozzle cannot meet the dust reduction demand, which not only affects the quality of working environment, but also causes workers to inhale a large amount of dust, causing serious harm to health, therefore, how to realize multi-angle adjustment of nozzle and improve dust reduction efficiency becomes an important problem to be solved for the existing roadway heading machine.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

The outer wall of the cutting disc of the tunnel boring machine 1 is provided with cutting teeth 4. A fixed plate 2 is fixedly connected to the top of the tunnel boring machine 1. A nozzle 8 is provided on the outer wall of the fixed plate 2. An adjustment assembly is provided on the top of the tunnel boring machine 1. A disassembly assembly is provided inside the tunnel boring machine 1. The adjustment assembly includes a first motor 5.

The outer wall of the rotating frame 6 is rotatably connected to the outer wall of the fixed plate 2. A worm gear 9 is rotatably connected inside the rotating frame 6. A transmission plate 7 is fixedly connected to the outer wall of the worm gear 9. The outer wall of the transmission plate 7 is located on the outer wall of the nozzle 8. A second motor 10 is rotatably connected to the outer wall of the fixed plate 2. A worm 11 is fixedly connected to the output end of the second motor 10. The worm 11 meshes with the worm gear 9. The outer wall of the second motor 10 is fixedly connected to the outer wall of the rotating frame 6. The worm 11 is rotatably connected inside the rotating frame 6.

[0023] The assembly and disassembly assembly includes a fixing ring 3, the outer wall of which is fixedly connected to the outer wall of the tunneling machine 1.

[0024] A connecting ring 14 is slidably connected inside the fixed ring 3, and one end of the connecting ring 14 is fixedly connected to the outer wall of the nozzle 8.

[0025] A fixed frame 13 is fixedly connected inside the fixed ring 3. An electric push rod 12 is fixedly connected to the bottom of the fixed frame 13. A lifting housing 16 is fixedly connected to the output end of the electric push rod 12.

[0026] A fixed column 21 is fixedly connected to the top of the fixed frame 13, and the interior of the lifting housing 16 is slidably connected to the outer wall of the fixed column 21. A rotating rod 17 is also rotatably connected to the outer wall of the fixed column 21.

[0027] One end of the rotating rod 17 is rotatably connected to a clamp 15, and the bottom of the clamp 15 is slidably connected to the top of the fixed frame 13.

[0028] The fixed frame 13 is internally fixedly connected to a fixed block 20, and the outer wall of the lifting housing 16 is rotatably connected to a transmission rod 18.

[0029] The transmission rod 18 is rotatably connected to the rotating rod 17, and sliding columns 19 are fixedly connected to both sides of the transmission rod 18. The outer wall of the sliding column 19 is slidably connected to the inside of the fixed block 20.

[0030] The cutting tooth 4 is a key component that directly contacts coal and rock for crushing operations. Its head is inlaid with ultra-hard carbide cutting teeth. These cutting teeth have extremely high hardness and can easily crush coal and rock of various hardnesses. The rod of the cutting tooth 4 is made of high-strength alloy steel, which has good toughness and rigidity, ensuring that it will not break under high-speed rotation and impact. The top of the tunneling machine 1 is fixedly connected to the fixing plate 2. The fixing plate 2 is made of thick steel plate, which has been precision machined and heat-treated, and has high strength and flatness. The outer wall of the fixing plate 2 is equipped with nozzles 8. The nozzles 8 are made of high-quality stainless steel, which has good corrosion resistance. Its internal design has fine spray channels, which can evenly atomize water into fine water droplets to achieve efficient dust suppression.

[0031] The fixing frame 13 is made of thick steel plate through processes such as cutting, bending and welding. Its shape is reasonably designed and can provide stable support for other components. The fixing column 21 is made of solid high-strength alloy steel bar. Its surface is precision ground and chrome-plated, which has good wear resistance and smoothness. The transmission rod 18 and the rotating rod 17 are rotatably connected through a joint bearing, which can flexibly transmit motion and force.

[0032] In practical applications, during tunnel excavation, the cutting tooth 4 generates a large amount of dust during high-speed operation, posing a serious threat to the working environment and personnel health. Simultaneously, as the cutting tooth 4 excavates, the nozzle 8 is activated to spray water mist onto the dust-generating area, effectively preventing dust from flying around and greatly improving the working environment. To further enhance dust suppression, a second motor 10 can be activated depending on the specific excavation conditions. After the second motor 10 starts, it drives the worm gear 11 to rotate smoothly inside the rotating frame 6. Because the worm gear 11 meshes with the worm wheel 9, the rotation of the worm gear 11 drives the worm wheel 9 to rotate. The rotation of wheel 9 drives the connected transmission plate 7, thereby adjusting the longitudinal angle of nozzle 8. To adjust the lateral angle of nozzle 8, the first motor 5 is started, which drives the rotating frame 6 to rotate. During this process, the rotating frame 6 drives the second motor 10 to rotate as well. This avoids jamming caused by the rotating frame 6 driving the worm gear 9. The rotation of the rotating frame 6 drives the worm gear 9 to rotate, which in turn drives the transmission plate 7 to rotate laterally, thereby driving the nozzle 8 to rotate laterally. Through adjustment, nozzle 8 can spray precisely at different angles, greatly improving dust suppression efficiency and providing a better environmental guarantee for tunnel excavation work.

[0033] During the interval when the tunnel boring machine 1 stops tunneling, the electric push rod 12 is activated to push the lifting housing 16. The lifting housing 16 slides slowly along the outer wall of the fixed column 21. As the lifting housing 16 moves, the transmission rod 18 is driven to rotate. The transmission rod 18 then drives the sliding column 19 to rotate synchronously inside the fixed block 20, preventing jamming and ensuring smooth operation of the machine. The transmission rod 18 continues to exert force, driving the rotating rod 17 to rotate, which in turn pushes the clamp 15 to move smoothly. Finally, the clamp 15 successfully slides the connecting ring 14 out of the fixed ring 3, making the cutting tooth 4 convenient and allowing for quick maintenance or replacement, laying the foundation for the efficient development of subsequent tunneling work.

[0034] Working principle: When tunneling through the cutting teeth 4, dust can be sprayed through the nozzles 8 to prevent dust from flying around. At the same time, the second motor 10 can be started as needed. The second motor 10 drives the worm gear 11 to rotate inside the rotating frame 6. Then, the worm gear 11 drives the meshing worm wheel 9 to rotate, which in turn drives the transmission plate 7 to rotate, thereby adjusting the longitudinal angle of the nozzles 8. The first motor 5 can also be started, which drives the rotating frame 6 to rotate. The rotating frame 6 drives the second motor 10 to rotate, preventing the rotating frame 6 from causing the worm wheel 9 to jam when rotating. The rotating frame 6 drives the worm wheel 9 to rotate, which in turn drives the transmission plate 7 to rotate laterally, thereby driving the nozzles 8 to rotate laterally. This allows for spraying at different angles, improving dust suppression efficiency.

[0035] In addition, when tunneling stops, the electric push rod 12 can be activated, which drives the lifting housing 16 to slide on the outer wall of the fixed column 21. Then, the lifting housing 16 drives the transmission rod 18 to rotate, and the transmission rod 18 drives the sliding column 19 to rotate inside the fixed block 20 to prevent jamming. Then, the transmission rod 18 drives the rotating rod 17 to rotate, thereby pushing the clamp 15 to move, so that the connecting ring 14 can slide out from inside the fixed ring 3, making it convenient to disassemble and install the cutting tooth 4 for maintenance or replacement.
