Description

Technical Field

[0001] This invention relates to the field of coal mining technology, and in particular to a coal mining backfilling tunneling device. Background Technology

[0002] Coal mining backfill tunneling machines are key equipment in the coal mining field. Their main function is to simultaneously carry out tunneling and backfilling operations during coal mining, thereby improving mine mining efficiency, ensuring mining safety, effectively controlling surface subsidence, and reducing the impact on the surrounding environment.

[0003] However, during coal mining, the high-speed friction between the drill bit and the rock strata generates a large amount of dust and smoke. Existing equipment mostly relies on a single dustproof structure, which is ineffective in preventing dust from spreading into the working environment. This not only severely obstructs the vision of construction workers but also interferes with the accuracy of their operations. Simultaneously, mined coal often contains a large amount of moisture. When collected, wet coal easily adheres to the surface of conveyor components, causing accumulation and blockages. During transportation, the high moisture content increases the transport load, reduces transfer efficiency, and consequently increases operating costs and time consumption, affecting the overall mining progress.

[0018] (III) Beneficial Effects

[0019] The beneficial effects of this invention are:

[0020] This invention discloses a coal mine backfilling tunneling device, comprising a main body, a tunneling mechanism, a collection mechanism, and a conveying and dehumidifying mechanism. The tunneling mechanism includes a drill bit, a first drive assembly, and a cooling and dust suppression assembly. The first drive assembly is mounted on the main body and is rotatably connected to the drill bit, enabling the drill bit to adjust its angle horizontally and vertically. The cooling and dust suppression assembly is connected to the drill bit and is used to cool the drill bit and spray it onto the excavation area to suppress dust. While cooling the drill bit to extend its service life, it can also precisely spray dust onto the excavation area, suppressing the spread of dust and smoke at the source of dust generation, preventing dust from obstructing the vision of construction personnel and interfering with operational accuracy, while reducing the harm of dust to the health of construction personnel and improving dust control effectiveness.

[0038] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] like Figure 1As shown, this embodiment provides a coal mine mining and backfilling tunneling device, which includes a main body 1, a tunneling mechanism 2, a collection mechanism 3, a conveying and dehumidifying mechanism 4, an operating platform mechanism 5, a fixing and supporting mechanism 6, and a filling mechanism 7. Through the coordinated operation of these seven mechanisms, the device solves technical problems in existing technologies such as poor dust removal efficiency, low coal mine transportation efficiency, and asynchronous tunnel excavation and reinforcement. It achieves integrated functionality encompassing tunneling, dust suppression, collection, dehumidification, personnel protection, main body fixing, and tunnel reinforcement, improving operational efficiency while reducing dust concentration in the working environment and significantly decreasing the risk of tunnel collapse. This provides comprehensive equipment support for safe and efficient underground coal mining. This integrated design breaks the limitations of traditional devices where functional modules are independent, forming an organic whole with closely connected operational processes. It eliminates the need for additional auxiliary equipment, significantly reducing the equipment's footprint and underground working space requirements.

[0040] The tunneling mechanism 2 includes a drill bit 21, a first drive assembly 22, and a cooling and dust suppression assembly 23. The first drive assembly 22 is mounted on the main body 1 and is rotatably connected to the drill bit 21, enabling the drill bit 21 to adjust its angle horizontally and vertically. Compared to the fixed digging direction of existing devices, this multi-angle adjustment structure eliminates the need for frequent machine movement, adapting to tunnel excavation requirements with different orientations and cross-sectional shapes. It is particularly suitable for tunnel development under complex geological conditions, significantly reducing preparation time and equipment adjustment costs. The multi-angle adjustment function not only improves operational flexibility but also precisely adapts to tunnel design requirements, reducing over-excavation and under-excavation during the excavation process, decreasing tunnel repair workload, saving manpower and time costs, and avoiding equipment wear and ground damage caused by frequent machine movement.

[0041] The cooling and dust suppression component 23 is connected to the drill bit 21 and is used to cool the drill bit 21 and spray it onto the excavation area to suppress dust. While cooling the drill bit 21 to extend its service life, it can also precisely spray dust onto the excavation area, suppressing the spread of dust and smoke at the source. This prevents dust from obstructing the vision of construction workers, interfering with operational accuracy, and reducing the health hazards of dust to construction workers, thus improving dust control effectiveness. Furthermore, compared to traditional end-of-pipe dust collection, this source-based dust suppression mode reduces dust adhesion and corrosion to equipment surfaces, lowers equipment maintenance frequency and difficulty, and extends the overall service life of the equipment.

[0042] like Figure 2As shown, the collection mechanism 3 is rotatably connected to the front end of the main body 1. It receives the coal drilled by the drill bit 21 and guides it to the conveying and dehumidifying mechanism 4. The collection mechanism 3 is rotatably connected to the main body 1, allowing for flexible angle adjustment to match the drilling position of the drill bit 21. This ensures efficient receipt of the drilled coal and accurate guidance to the conveying and dehumidifying mechanism 4, preventing coal spillage and collection losses. This adjustable collection structure improves the coal collection rate, especially in inclined roadway excavation, effectively preventing coal from rolling down into the work area, ensuring operational safety and reducing resource waste. The efficient collection reduces coal loss during mining, improves resource utilization, and prevents scattered coal from accumulating in the work area, affecting equipment movement and personnel access. This reduces the additional labor intensity caused by cleaning up scattered coal, further improving overall operational efficiency.

[0043] like Figure 3 As shown, the conveying dehumidification mechanism 4 includes a conveying component 41 and an air outlet component 42. The surface of the conveying component 41 has drainage holes for receiving coal guided by the collection mechanism 3 and conveying it from the beginning to the end. The air outlet component 42 is positioned corresponding to the conveying direction of the conveying component 41 and is used to blow air onto the coal on the conveying component 41 to dehumidify it. The drainage holes are used to discharge the dehydrated coal. The drainage holes on the surface of the conveying component 41, combined with the air outlet component 42 positioned along the conveying direction, achieve the function of blowing air to dehumidify the wet coal and quickly discharging moisture. This effectively prevents wet coal from adhering to the surface of the conveying components and causing blockages, reducing the transport load, improving coal transfer efficiency, reducing operating costs and time consumption, and ensuring the continuity of the overall mining progress. In practical applications, this conveying dehumidification mechanism 4 can reduce the moisture content of the coal from approximately 35% to below 12%, and the conveying blockage rate to below 1%, greatly reducing the time spent interrupting operations due to blockage clearing and ensuring the continuous and stable mining process. Continuous and stable conveying operations avoid efficiency losses caused by frequent shutdowns. Dehumidified coal is less prone to caking and deterioration during subsequent storage and transportation, reducing losses during storage and transportation, while also alleviating the load pressure on transportation equipment and extending its service life.

[0044] like Figure 3As shown, the conveying assembly 41 includes a conveyor belt 411 and a drive unit 412. The drive unit 412 drives the conveyor belt 411 to rotate, and multiple drainage holes are provided on the conveyor belt 411. The conveyor belt 411 is made of a wear-resistant rubber and polyester fiber composite material, and the surface can be provided with anti-slip protrusions. Combined with the evenly distributed drainage holes, it can enhance the friction between the coal mine and the conveyor belt 411, preventing slippage during the conveying process, and can also quickly drain the removed moisture, avoiding coal particle blockage. The choice of wear-resistant composite material enables the conveyor belt 411 to resist the friction and impact of coal particles, extending the replacement cycle of the conveyor belt 411. The anti-slip protrusion design further ensures the stability of the conveying process, effectively preventing coal mine slippage even in high-speed or inclined conveying scenarios, and reducing secondary losses during the conveying process.

[0045] like Figures 4-6 As shown, the air outlet assembly 42 includes a blower, an air box 421, and multiple heating pipes 422. The air box 421 is positioned above the conveyor belt 411 and extends along the conveying direction of the conveyor belt 411. Multiple heating pipes 422 are spaced apart inside the air box 421. An air inlet 4211 is opened on one side of the air box 421, and the blower is connected to the air inlet 4211. Multiple air outlets 4212 facing the conveyor belt 411 are opened at the bottom of the air box 421. The extended design of the air box 421 and the evenly distributed air outlets 4212 ensure that the coal mine receives uniform airflow throughout the entire conveying path, resulting in consistent dehumidification. The arrangement of the heating pipes 422 can be flexibly adjusted according to the ambient temperature and the moisture content of the coal mine, ensuring good dehumidification even in low-temperature environments, making the device adaptable to underground operations under different climatic conditions.

[0046] In this embodiment, the heating tube 422 adopts a composite integrated protection and heat dissipation structure, comprising, from the inside out, a heating rod, an explosion-proof and flame-retardant layer, and rectifier heat dissipation strips. These three components are arranged coaxially along the radial direction, resulting in a compact structure and coordinated functions. The explosion-proof and flame-retardant layer is made of non-combustible, high-temperature resistant ceramic fiber material, tightly wrapping around the heating rod. This physically isolates the heating rod from the dust-laden airflow within the air box 421, preventing coal dust or combustible particles from directly contacting the high-temperature surface of the heating rod. Structurally, this blocks the path to deflagration, meeting the explosion-proof requirements of underground coal mine operations. Multiple rectifier heat dissipation strips are evenly arranged circumferentially on the outside of the explosion-proof and flame-retardant layer, forming multiple longitudinal airflow channels between adjacent strips to facilitate heat dissipation from the heating rod.

[0047] like Figure 7As shown, the first drive assembly 22 includes a rotary seat, a connecting block 222, a mounting plate 223, and a rotating seat 224. The rotary seat is mounted on the main body 1, and the connecting block 222 is connected to the rotary seat. The rotary seat adopts a high-precision worm gear transmission structure, which has high transmission accuracy and good self-locking performance, and can achieve arbitrary angle positioning of the drill bit 21 in the horizontal direction from 0-360°. The connecting block 222 is forged from an integral alloy steel, which has high strength and strong resistance to deformation, ensuring stable power transmission during excavation. The mounting plate 223 is located at the front end of the connecting block 222. The drill bit 21 is hinged to the mounting plate 223 through the rotating seat 224, and the drill bit 21 is rotatably connected to the rotating seat 224. The rotating seat 224 adopts a double-axis hinge structure, which, together with the servo motor drive, can achieve precise adjustment of the drill bit 21 in the vertical direction from 30° to 60°, meeting the needs of various operating scenarios such as horizontal excavation, inclined excavation, and vertical excavation. Compared with traditional single-angle excavation devices, it has stronger adaptability and more flexible operation.

[0048] like Figure 1 and Figure 7 As shown, the cooling and dust suppression assembly 23 includes a water pump 231, a water tank 232, and a water pipe 233. A water flow channel is opened inside the drill bit 21, and a spray nozzle 211 is opened at the head of the drill bit 21, which is connected to the water flow channel. One end of the water pipe 233 is connected to the water tank 232, and the other end is connected to the inlet of the water flow channel. The water tank 232 is mounted on the main body 1 and is made of stainless steel, providing corrosion and rust resistance. A liquid level warning device is installed on the top, automatically alarming when water is insufficient to ensure uninterrupted operation. The stainless steel water tank 232 can adapt to the humid and corrosive gas environment underground, extending its service life. The liquid level warning device provides operators with a convenient means of monitoring the status, preventing the cooling and dust suppression function from failing due to water shortage, and ensuring the continuity and safety of operations.

[0049] Water pump 231 is mounted on water tank 232 and connected to water pipe 233. Water pump 231 is a high-pressure variable frequency pump, which can automatically adjust the water supply pressure and flow rate according to the excavation intensity and dust concentration, achieving an optimal balance between cooling and dust suppression effects and water consumption. The automatically adjusted water supply mode ensures effective dust suppression in high-intensity excavation and high-dust-generating scenarios while avoiding water waste during low-intensity operations.

[0050] like Figure 2As shown, the collecting mechanism 3 includes a collecting platform 31 and two sets of second drive components 32. The collecting platform 31 is located at the front end of the main body 1, and the two sets of second drive components 32 are symmetrically arranged on both sides of the collecting platform 31 to synchronously drive the collecting platform 31 to rotate up and down to adjust the receiving angle. The symmetrical arrangement of the two sets of second drive components 32 ensures that the force on the collecting platform 31 is uniform when it rotates, avoiding deformation or jamming caused by force on one side, and avoiding angle adjustment deviation caused by uneven force on one side, thus ensuring the accuracy of coal receiving and further improving the collecting efficiency.

[0051] like Figure 2 As shown, the second drive assembly 32 includes a drive wheel 321, a driven wheel 322, and a belt 323. The drive wheel 321 is located on the side wall of the main body 1, and the driven wheel 322 is located on one side of the collection platform 31. The belt 323 is sleeved on the drive wheel 321 and the driven wheel 322. The rotation of the drive wheel 321 drives the collection platform 31 to rotate. The drive wheel 321 is driven by a stepper motor with adjustable speed. Combined with the synchronous belt 323, the transmission accuracy is high and there is no slippage. This ensures that the angle adjustment of the collection platform 31 is precise and controllable. Compared with gear transmission, the operating noise is lower and the maintenance cost is lower. The collection platform 31 has a recessed collection groove 311. The collection groove 311 is set from the near end to the far end in the forward direction. At least one sweeping plate 33 is rotatably installed in the collection groove 311. The sweeping plate 33 is used to guide the coal in the collection groove 311 to the conveying and dehumidification mechanism 4. By setting up the sweeping plate 33, the problem of coal sticking and accumulating in the collection trough 311 is avoided, ensuring that the collection trough 311 is always unobstructed and does not require manual cleaning, further reducing the labor intensity of operators and improving the level of automation of the operation.

[0052] like Figure 1 and Figure 8 As shown, the operating platform mechanism 5 includes a worktable 51 and a support assembly 52. ​​The worktable 51 is located at the top of the main body 1. The support assembly 52 includes a fixed platform 521, an anchor rod 522, and multiple electric telescopic rods 523. The fixed ends of the multiple electric telescopic rods 523 are connected to the top of the worktable 51, and the telescopic ends of the electric telescopic rods 523 are connected to the fixed platform 521. The anchor rod 522 is located on the fixed platform 521. An operating space is provided inside the worktable 51.

[0053] like Figure 1 and Figure 9As shown, the fixed support mechanism 6 includes a support frame 61, a hydraulic rod 62, and a support base 63. The support frame 61 is located on one side of the main body 1. The fixed end of the hydraulic rod 62 is connected to the support frame 61, and the telescopic end of the hydraulic rod 62 is connected to the support base 63. The support base 63 is made of a large-area steel plate, providing a large ground contact area to distribute the pressure on the machine body and prevent sinking on soft ground. Multiple insertion rods 64 are spaced apart at the bottom of the support base 63. The close contact between the large-area support base 63 and the ground further enhances the stability of the device. The insertion rods 64 form a "surface-point" combined support mode, which can firmly fix the device position even on soft or uneven underground ground, effectively resisting digging vibrations and external impacts, and providing a reliable guarantee for the stable operation of each mechanism.

[0054] like Figure 1 As shown, the filling mechanism 7 includes a cement tank 71, a cement pump 72, and a grouting pipe 73. The cement tank 71 is located on the main body 1 of the machine. An automatic mixing device is installed inside the cement tank 71 to prevent cement mortar from settling and solidifying, ensuring uniform grouting quality. The inner wall of the tank is coated with an anti-stick coating for easy cleaning and reduced waste. The automatic mixing device prevents cement mortar from settling and solidifying during storage, ensuring the uniformity and fluidity of the grouting material and improving the reinforcement effect. The anti-stick coating simplifies the cleaning of the cement tank 71, reduces material residue and equipment wear, and lowers maintenance costs.

[0055] One end of the grouting pipe 73 is connected to the cement tank 71, and the other end extends towards the tunnel sidewall. The grouting pipe 73 uses a high-pressure wear-resistant flexible hose to adapt to the reinforcement needs of different locations in the tunnel. A rotatable grouting nozzle is installed at the end, providing a wide grouting range and good uniformity. The cement pump 72 is mounted on the cement tank 71 and connected to the grouting pipe 73. The cement pump 72 is a plunger-type high-pressure pump with stable output pressure and adjustable grouting flow rate to adapt to different gap sizes and reinforcement thickness requirements.

[0056] In actual operation, the coal mining backfilling tunneling device of the present invention, with the various mechanisms working together, forms a complete integrated operation process of "excavation-dust suppression-collection-dehumidification-reinforcement": First, the machine body is firmly fixed by the fixed support mechanism 6 to prevent displacement during operation; after the tunneling mechanism 2 is started, the first drive component 22 drives the drill bit 21 to adjust to the preset angle for excavation, and the cooling and dust suppression component 23 works simultaneously to cool the drill bit 21 and suppress dust diffusion. The collection mechanism 3 efficiently collects the excavated coal and guides it to the conveying and dehumidification mechanism 4 through the adjustable collection platform 31 and the sweeping plate 33; the conveying component 41 drives the coal conveying, and the air outlet component 42 quickly reduces the moisture content of the coal through hot air dehumidification and drainage holes to ensure smooth transportation; the operating platform mechanism 5 provides a safe and comfortable operating environment for the operators, while the support component 52 can promptly fix the tunnel top with anchor bolts 522, and the filling mechanism 7 simultaneously reinforces the tunnel sidewalls and top with cement mortar grouting. This integrated operation process organically combines multiple previously independent operation links, significantly shortening the operation cycle, reducing the connection time between each link, and improving overall operation efficiency. At the same time, the synergistic effect of each mechanism enables simultaneous improvement in operation safety, resource utilization, and reinforcement quality. Compared with traditional mining equipment, it has significant comprehensive performance advantages and provides strong support for the safe and efficient development of the coal mining industry.
