Description

Technical Field

[0001] This utility model relates to the field of coal mine tunneling technology, and in particular to a rapid coal mine tunneling device. Background Technology

[0002] A coal mine is an area where humans extract coal resources in coal-rich areas, generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, underground tunnels are typically dug to extract the coal; this is called an underground coal mine. When the coal seam is very close to the surface, the surface soil is typically stripped away to extract the coal; this is called an open-pit coal mine. The vast majority of coal mines in my country are underground mines. A coal mine encompasses a large area, including both above-ground and underground areas, as well as related facilities. A coal mine is a rationally excavated space created by humans when mining coal-rich geological strata, typically including tunnels, shafts, and working faces. Coal is the most important solid fuel, a type of combustible organic rock. It is formed from abundant vegetation that grew in a specific geological era, gradually accumulating into thick layers under suitable geological conditions, buried underwater or in silt, and undergoing natural coalification over long geological periods. Among the world's geological periods, the Carboniferous, Permian, Jurassic, and Tertiary strata contain the most coal and are considered important coal-forming eras. Coal typically contains 46% to 97% carbon, and ranges in color from brown to black with a dull to metallic luster. Based on its degree of coalification, coal can be classified into four categories: peat, lignite, bituminous coal, and anthracite.

[0003] The prior art, with publication number CN220869391U, discloses a rapid coal mine tunneling device, including a base plate with casters at the bottom and a box and shielding assembly at the top. A partition plate connects to the inner wall of the box, dividing it into a first chamber and a second chamber. A motor is installed in the first chamber, with a transmission rod fixedly connected to the motor's output shaft. The end of the transmission rod away from the motor extends out of the box and is fixedly connected to a drill bit. A dust suppression assembly is located at the top of the box, including an atomizing nozzle, a nozzle mounting base, pipes, and a water pump. This invention utilizes the shielding assembly to block coal falling during tunneling, preventing it from falling in front of the tunneling device and facilitating its movement. The dust suppression assembly treats the dust generated during tunneling. The water pump transports water from the second chamber through pipes to the atomizing nozzle, spraying out mist to suppress dust and ensure the breathing safety of workers.

[0004] However, the aforementioned existing technology still has certain shortcomings in its use: First, the existing technology uses a baffle set directly below the drill bit to guide the excavated coal to both sides to prevent it from falling in front of the tunneling device. However, the baffle and the caster wheels are at a certain height, and the baffle can only move horizontally. This causes the coal on both sides to accumulate and roll down in front of the caster wheels, obstructing progress and affecting the tunneling speed. Second, the baffle and the caster wheels are at a certain height, and the baffle can only move horizontally back and forth, which hinders the probe from excavating coal at lower positions. This prevents the coal below the baffle from being pushed aside to both sides, blocking the tunneling device's progress. Consequently, manual or external equipment is needed to clear and transfer the coal before the tunneling device can continue tunneling. The design is unreasonable, and therefore, the existing technology needs further improvement. Utility Model Content

[0012] Preferably, the vehicle body has a water-carrying compartment inside, a water pump is installed on the top surface of the vehicle body, the input end of the water pump is connected to a connecting pipe one, the end of the connecting pipe one away from the water pump extends close to the bottom of the compartment, the connecting pipe one is a rigid pipe, limit blocks are fixedly installed on the top surface of the vehicle body and the top surface of the semi-circular part, the output end of the water pump is connected to a connecting pipe two, the other end of the connecting pipe two passes through the two limit blocks, and the atomizing nozzle is connected to one end of the connecting pipe two away from the water pump, the connecting pipe two is a flexible pipe.

A slot is opened at one end of the bucket near the vehicle body, directly above one end of the conveyor belt and below the material-pushing plate when the material-pushing wheel rotates.

[0015] Preferably, the two limiting plates are symmetrically hinged to each other with hydraulic telescopic cylinders three. The moving end of the hydraulic telescopic cylinder three is hinged to the bottom surface of the bucket. When the bucket is horizontal, the hydraulic telescopic cylinder three is in a semi-extended state.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this application, a coal mining mechanism is installed on the front side of the vehicle body. The coal mining mechanism includes a rotating drill bit. The drill bit can swing horizontally left and right through the cooperation of motor 2, gears, arc rack, rotating parts, and rectangular strip, thereby adjusting the width of the mining. Through the cooperation of hydraulic telescopic cylinder 2, rectangular strip, and mounting parts, the drill bit can be adjusted vertically, thereby adjusting the mining height. Through the cooperation of hydraulic telescopic cylinder 1, rectangular strip, and column, the drill bit can be adjusted horizontally front and rear (the orientation descriptions are all based on the rear side of the vehicle body as the front view), thereby adjusting the mining depth. In summary, the rotating drill bit can mine any size space of the ore body through the drive of hydraulic telescopic cylinder 1, hydraulic telescopic cylinder 2, and motor 2. Compared with the prior art, this improves the flexibility of the tunneling device, increases tunneling efficiency, and has a more reasonable design.

[0018] 2: In this application, a dust suppression mechanism is installed directly above the coal mining mechanism. The dust suppression mechanism includes an atomizing nozzle, which is mounted on a rotating component and can swing horizontally in sync with the drill bit. This ensures that the atomizing nozzle is always directly above the drill bit, improving the dust suppression effect of the mist water source. Furthermore, the atomizing nozzle, through the cooperation of a motor, a disc, a cylinder, a semi-circular component, and a rectangular strip, can reciprocate in an arc shape with the atomizing nozzle connected to the flexible connecting pipe. This results in a larger spray range of the mist water source, increasing the dust suppression range and making the dust suppression and removal effect more comprehensive and thorough. This improves the environmental quality of the tunneling work, reduces the harm of smoke and dust to workers, and is more practical.

[0019] 3: This application includes a coal mine conveying mechanism, which comprises a bucket, a feed wheel, and a conveyor belt. The tail end of the bucket is hinged to the front of the vehicle body and the bucket is located below the drill bit. The feed wheel rotates symmetrically on the inclined surface of the bucket. The conveyor belt is located directly below the middle of the tail end of the bucket. Two motors drive the two feed wheels to rotate alternately towards the middle, so that the two rotating feed wheels can continuously feed the mined coal and mineral material towards the conveyor belt (i.e., the tail end of the bucket). This allows the coal and mineral material mined in front to be continuously transported to the rear of the vehicle body via the conveyor belt, effectively avoiding the situation where the tunneling device stops working due to manual transfer. This greatly reduces the labor intensity of the workers and effectively improves the tunneling speed and efficiency.

[0020] 4: In this application, the tail end of the inclined surface of the bucket is provided with an arc surface tangent to the outermost end of the material-pushing plate of the material-pushing wheel. This ensures that there is no gap space at the end of the material-pushing plate of the material-pushing wheel away from the front side of the bucket (i.e., the end closest to the conveyor belt). Consequently, the end of the material-pushing wheel close to the conveyor belt will not accumulate material, thereby reducing the situation of material accumulation and overflow to both sides. This avoids the impact of overflow on the excavation, reduces the cleaning work of the bucket, and makes the design more reasonable and practical.

[0021] 5: In this application, hydraulic telescopic cylinders three are symmetrically hinged on the limiting plates on both sides of the conveyor belt. The moving end of the hydraulic telescopic cylinder three is hinged to the bottom surface of the bucket. Thus, the front end of the bucket can be driven to deflect towards or away from the bottom surface of the mine through the hydraulic telescopic cylinder three. When the front end of the bucket contacts the bottom surface of the mine, work can begin. When the front end of the bucket moves away from the bottom surface of the mine, it is beneficial to move the tunneling device.

[0022] 6: In this application, the front end of the bucket is wider than the track wheels on both sides, which can prevent the accumulation of coal and mineral materials in front of the track wheels and avoid affecting the forward efficiency of tunneling. Attached Figure Description

[0034] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0035] Please see Figure 1-7 The present invention will now be described in detail with reference to the accompanying drawings and embodiments: A rapid coal mine tunneling device includes a vehicle body 1, tracked wheels 2 on both sides of the vehicle body 1, a coal mining mechanism at the front end of the vehicle body 1, a dust removal mechanism above the coal mining mechanism, and a coal conveying mechanism below the coal mining mechanism.

[0036] Please see Figure 1-3The coal mining mechanism includes a rotating component 3. An arc-shaped rotating groove 4 is provided on the front side of the vehicle body 1. An arc-shaped surface is provided at the vertical end of the rotating component 3, and the arc-shaped surface of the rotating component 3 is rotatably positioned within the arc-shaped rotating groove 4.

A limiting strip is provided, with mounting blocks 9 fixedly installed at the middle of both ends of the limiting strip. A hydraulic telescopic cylinder 10 is fixedly installed on both sides of the rectangular strip 6. The moving ends of the hydraulic telescopic cylinder 10 are fixedly connected to the sides of the corresponding mounting blocks 9. A motor 11 is embedded in the end of the column 8 away from the vehicle body 1. A drill bit 12 is fixedly installed on the output shaft of the motor 11. By extending or retracting the hydraulic telescopic cylinder 10, the column 8 can move in the front and back directions, so that the drill bit 12 driven by the motor 11 can mine the ore body at any depth.

[0037] Please see Figure 1-2 A rectangular strip 6 is symmetrically fixed with mounting block 2 13 on its top surface, and a rotating part 3 is symmetrically fixed with mounting block 3 14 on its horizontal end. A hydraulic telescopic cylinder 2 15 is hinged between the mounting blocks 3 14. The moving end of the hydraulic telescopic cylinder 2 15 is hinged between the mounting blocks 2 13. By extending or retracting the hydraulic telescopic cylinder 2 15, the rectangular strip 6 can be deflected in the vertical direction, thereby allowing the drill bit 12 to adjust the height position of the ore body mining.

[0038] Please see Figure 2-3 An arc-shaped groove 16 is provided in the middle of the arc-shaped rotating groove 4. An identical rotating groove 17 is provided on the side of the arc-shaped groove 16 away from the rotating component 3. An arc-shaped rack 18 is fixedly provided on the arc-shaped surface of the rotating component 3. A gear 19 is rotatably provided in the rotating groove 17 and meshes with the arc-shaped rack 18. A receiving groove is provided below the gear 19. A motor 20 is fixedly provided in the receiving groove. One end of the motor 20 is fixedly connected to the gear 19. The motor 20 can be installed by providing a channel on one side of the vehicle body 1 that communicates with the receiving groove. A sliding door (not shown) is provided at the outer end of the channel. The motor 20 drives the gear 19 to rotate. The rotation of the gear 19 drives the arc-shaped rack 18 to rotate. The rotation of the arc-shaped rack 18 drives the rotating component 3 to rotate. The rotation of the rotating component 3 drives the rectangular bar 6 to rotate. The rotation of the rectangular bar 6 drives the drill bit 12 to deflect in the horizontal direction. In combination with the forward and backward movement and the vertical movement, it is possible to mine any size space of the ore body.

[0039] Please see Figure 1-24-5, The dust removal mechanism includes an atomizing nozzle 21, a motor 22 is embedded and fixedly installed on the top surface of the rotating part 3, a disc 23 is fixedly installed at the output end of the motor 22, the bottom surface of the disc 23 is in rotatable contact with the top surface of the rotating part 3, a cylinder 24 is fixedly installed eccentrically on the top surface of the disc 23, a limit post 25 is fixedly installed on the top surface of the rotating part 3, a semi-circular part 26 is rotatably installed at the top of the limit post 25, a rectangular strip 27 is provided on the plane of the semi-circular part 26, a groove 28 is opened on the rectangular strip 27, and the cylinder 24 is slidably installed in the groove 28. The motor 22 drives the disc 23 to rotate, the disc 23 rotates and drives the eccentrically installed cylinder 24 to rotate together, and the rotating cylinder 24 drives the rectangular strip 27 and the semi-circular part 26 to reciprocate in an arc swing around the limit post 25.

[0040] Please see Figure 1 , 5 A cover 29 is fixedly provided on the top surface of the rotating part 3. The cover 29 can cover the rectangular bar 27, the cylinder 24 and the disk 23 and provide space for the rectangular bar 27 to deflect. The other end of the cover 29 extends to a part of the top surface of the vehicle body 1 and is in contact with the top surface of the vehicle body. The cover 29 not only makes the rotating part 3 rotate more stably on the vehicle body 1, but also provides a certain support and protection for the parts.

[0041] Please see Figure 2-5 The vehicle body 1 has a water-carrying chamber 30 inside. A water pump 31 is installed on the top surface of the vehicle body 1. The input end of the water pump 31 is connected to a connecting pipe 32. The end of the connecting pipe 32 away from the water pump 31 extends close to the bottom of the chamber 30. The connecting pipe 32 is a rigid pipe. Limiting blocks 33 are fixedly installed on the top surface of the vehicle body 1 and the top surface of the semi-circular part 26. The output end of the water pump 31 is connected to a connecting pipe 34. The other end of the connecting pipe 34 passes through the two limiting blocks 33. The atomizing nozzle 21 is connected to the end of the connecting pipe 34 away from the water pump 31. The connecting pipe 34 is a flexible pipe, such as a corrugated pipe. The flexible connecting pipe 34 can adapt to the reciprocating swing of the semi-circular part 26. The atomizing nozzle 21 is set on the rotating part 3 and can swing synchronously with the drill bit 12 in the left and right horizontal direction, so that the atomizing nozzle 21 is always directly above the drill bit 12, which improves the dust suppression effect of the atomized water source.

[0042] Please see Figure 6-8The coal mine conveying mechanism includes a bucket 35. A rectangular slot 36 is provided at the bottom of the vehicle body 1. The bucket 35 is hinged at the front end of the vehicle body 1 and below the drill bit 12. The front end of the bucket 35 is wider than the track wheels 2 on both sides, which can prevent the accumulation of coal and mineral materials in front of the track wheels 2 and avoid affecting the forward progress of the tunneling. Symmetrical rotating feed wheels 37 are arranged on the inclined surface of the bucket 35. The two feed wheels 37 rotate alternately towards the center. The bucket 35 is close to the vehicle body. The inner side of bucket 35 (the tail end of the inclined surface) is provided with an arc surface 38 that is adapted to the feeding plate of feeding wheel 37. The arc surface 38 prevents coal ore from accumulating in the bucket 35 behind feeding wheel 37 when feeding. This avoids coal overflow onto the sides of bucket 35 due to empty space, thus improving the conveying efficiency of the coal under mining conditions. A motor 4 39 is symmetrically fixed to the bottom of bucket 35. The output end of motor 4 39... Fixedly connected to the feed wheel 37, a limiting plate 40 is symmetrically installed on the top surface of the rectangular groove 36. The limiting plate 40 is located between the two motors 39. A conveyor belt 41 is installed between the limiting plates 40. The conveyor belt 41 is higher than the bottom of the track wheel 2 and below the bucket 35. A slot 42 is opened at the end of the bucket 35 near the vehicle body 1. The slot 42 is directly above one end of the conveyor belt and below the feed plate when the feed wheel 37 rotates, thus facilitating the falling of mined coal onto the feed plate. On the lower conveyor belt 41, two limit plates 40 are symmetrically hinged to each other with hydraulic telescopic cylinders 43. The moving end of the hydraulic telescopic cylinder 43 is hinged to the bottom surface of the bucket 35. When the bucket 35 is horizontal, the hydraulic telescopic cylinder 43 is in a semi-extended state. By retracting the hydraulic telescopic cylinder 43, the bucket 35 can be deflected towards the bottom of the mine, so that the inlet of the bucket 35 contacts the bottom of the mine, thereby maximizing the transport of the mined coal to the rear.

[0043] When this scheme is in operation, firstly, the device is moved to the innermost part of the mine shaft to be mined via the track wheels 2. Then, the hydraulic telescopic cylinder 3 43 is activated to retract, causing the bucket 35 to gradually deflect towards the bottom of the mine shaft, until the front end of the bucket 35 contacts the bottom of the mine shaft. Then, motor 4 39 is activated, which drives the two feed wheels 37 to rotate simultaneously towards the center. Then, motors 1 11 and 3 22 are activated. Motor 1 11 drives the drill bit 12 to rotate, and motor 3 22 drives the disc 23 to start rotating, which in turn causes the semi-circular part 26 to begin reciprocating arc-shaped oscillation, thereby creating mist. The atomizing nozzle 21 reciprocates in an arc shape, and then the water pump 31 is started, so that the atomizing nozzle 21 begins to spray water in the form of mist, reducing the smoke and dust generated during ore mining, making it easier for the tunneling machine operator to observe, and reducing the harm of smoke and dust to the health of the workers. After the atomizing nozzle 21 is started, the hydraulic telescopic cylinder 2 15 is started. By extending or retracting the hydraulic telescopic cylinder 2 15, the height of the drill bit 12 can be adjusted in the vertical direction. It is best to start mining from the bottom and proceed from top to bottom to prevent coal from falling and obstructing the bottom, affecting the observation and determination of the bottom mining position.

[0044] When it is necessary to adjust the horizontal width, start motor 20, which drives gear 19, gear 19 drives arc rack 18, and arc rack 18 drives rotating part 3 to deflect at a certain angle along rotating groove 4, thereby enabling the rotating drill bit 12 to deflect horizontally (the deflection direction is controlled by the rotation direction of motor 20), thus realizing the adjustment of the horizontal mining position.

[0045] During the mining process, coal and mineral materials fall in front of the bucket 35 or directly onto the bucket 35. The coal and mineral materials inside the bucket 35 are then pushed backward by two material-pushing wheels 37 that rotate towards the center. During the pushing process, the materials pass through the slot 42 and then fall onto the conveyor belt 41 below. This gradually transports the mined coal and mineral materials from the front of the device to the rear, avoiding affecting the forward movement of the tunneling device.

[0046] As the device moves forward, the coal and mineral materials in front are drawn into the bucket 35 through the opening of the bucket 35, thus effectively transporting the coal and mineral materials further forward to the rear.

[0047] After tunneling a certain distance, the tunneling team retreats a certain distance to conduct roof checks, provide support and protection, and then continues tunneling, repeating this process.

[0048] Based on the above description in this specification, those skilled in the art will also understand that the following terms, such as "upper," "lower," "front," "rear," "left," "right," "inner," and "outer," which indicate orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as a limitation on the present invention.

[0049] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
