Description

Technical Field

[0001] This utility model relates to the field of mountain blasting technology, and more specifically to an integrated device for mountain drilling and gas blasting. Background Technology

[0002] When blasting rocky hills, the traditional technique involves workers standing and operating a pneumatic drill to drill blasting holes vertically downwards from the mountaintop edge. Although an air compressor supplies high-pressure air to the blasting holes through pressure-resistant pipes and hollow steel drill bits, the high-pressure gas blows out dust from the holes, causing workers operating the pneumatic drill to inhale large amounts of dust. Furthermore, after drilling the blasting holes, the pneumatic drill needs to be removed before inserting the blasting head. To maintain a safe distance during blasting, a sufficiently long air pipe is required connected to the blasting head. Workers also need to extend the air pipe and move the gas blasting device to a safe position before detonating. This process is complex, and the long safe distance requires a considerable amount of time to extend the air pipe. After blasting, it is also inconvenient to store the device, adding unnecessary time costs.

[0003] Therefore, how to provide an integrated device for drilling holes and gas blasting in mountains that can perform drilling and inserting blasting nozzles sequentially, and that facilitates the deployment and storage of the gas guide tube, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the present invention provides an integrated device for drilling and gas blasting in mountains, which integrates the three stages of drilling, pipe feeding, and blasting into a movable box. The device alone can independently complete the mountain blasting process of drilling, pipe feeding, and blasting. It uses a lifting drilling mechanism to replace an independent drilling machine, and a coiling mechanism and a blasting nozzle ejection mechanism to replace manual pipe lifting and insertion, thereby reducing labor intensity, avoiding manual approach to the borehole, and reducing the harm of the mountain environment to the human body. This solves the technical problems of existing technologies, such as the large dust impact of manual drilling, the long time required to deploy the gas pipe during blasting, and the inconvenience of storage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An integrated device for drilling holes and gas blasting in mountains, comprising:

[0007] A movable equipment box, the equipment box having a first side wall and a second side wall arranged opposite to each other, the first side wall being fixed with a push handle, and the second side wall having a construction opening;

[0008] A blasting hole drilling mechanism, wherein the blasting hole drilling mechanism can be lifted and installed inside the equipment box and close to the construction opening, and the drilling part of the blasting hole drilling mechanism can extend out of the construction opening to drill holes in the mountain;

[0009] A gas supply mechanism is arranged inside the equipment box and near the push handle;

[0010] A coiling mechanism is arranged inside the equipment box and close to the gas supply mechanism. The gas output port of the gas supply mechanism is connected to a gas guide pipe and can be coiled on the coiling mechanism.

[0011] A blasting nozzle ejection mechanism is installed at the top of the equipment box, with its output end arranged circumferentially with the construction port. A sleeve arranged coaxially with the construction port is provided at the top of the blasting nozzle ejection mechanism. The air guide pipe is slidably assembled in the sleeve, and its air outlet is connected to the blasting nozzle. One end of the blasting nozzle abuts against the circumferential wall of the sleeve, and the other end is provided with a radial locking component that can be locked into the blasting hole in the mountain.

[0012] As can be seen from the above technical solution, compared with the prior art, this utility model discloses an integrated device for drilling holes and gas blasting in mountains. The device box is pushed to the mountainside manually or by a small tractor, with the drilling opening aligned with the area to be blasted. The drilling mechanism is driven upwards, its output end extending from the drilling opening to complete drilling to a set depth. After drilling is complete, the device box is pulled out, removing the output end of the drilling mechanism from the blast hole, and then the drilling mechanism is returned to its original position. After drilling is complete, the blasting nozzle ejection mechanism is activated, coaxially extending the gas guide pipe along the sleeve until the blasting nozzle reaches the bottom of the hole. The radial locking assembly at the end of the blasting nozzle opens radially within the hole, forming an interference fit with the hole wall to prevent springback, thus locking the blasting nozzle into the blasting hole. Then, the coil mechanism is activated to unfold the gas guide pipe, simultaneously driving the equipment box away from the blasting hole to a safe area. After ensuring safety, the gas supply mechanism is activated to send high-pressure gas through the gas guide pipe into the blasting nozzle, completing the gas blasting of the mountain. After blasting, the radial locking assembly is released, the coil mechanism rotates in the opposite direction to retract the gas guide pipe, and the blasting nozzle ejection mechanism reverses its movement, retracting the blasting nozzle back into the equipment box. The entire box can then be moved to the next target hole location. By using this equipment, operators only need to operate from the pusher side, away from the hole opening and rockfall area, reducing the impact of falling rocks and dust on personnel. Drilling, pipe delivery, and gas filling are completed in one step, shortening working time, reducing the time for unfolding and retracting the gas guide pipe, and also reducing equipment relocation time, thus improving work efficiency.

[0013] Furthermore, the blasting hole drilling mechanism includes an air compressor, a lifting push rod, a pneumatic drill, and a steel rod. The air compressor is arranged at the bottom of the equipment box and away from the second side wall of the equipment box. The lifting push rod is installed on the inner bottom plate of the equipment box and close to the second side wall of the equipment box, and its output end is fixed with a mounting platform. The pneumatic drill is fixed on the mounting platform and its output end faces the second side wall of the equipment box. The input end of the pneumatic drill is connected to the output end of the air compressor through a high-pressure pipe. A trajectory hole is opened on the second side wall of the equipment box corresponding to the lifting trajectory of the steel rod. The first end of the steel rod is assembled to the output end of the pneumatic drill, and its second end is a conical tip that extends out of the trajectory hole.

[0014] The advantages of adopting the above technical solution are: the high-frequency impact energy is concentrated, which can still efficiently break rocks in medium-hard or hard rock layers; at the same time, there are no high-speed rotating parts, so it is not easy to get stuck or break the drill rod. On-site maintenance only requires periodic replacement of the steel drill bit, which reduces the maintenance frequency and maintenance cost.

[0015] Furthermore, the blasting hole drilling mechanism also includes a water storage tank. The output end of the air compressor is connected to the water storage tank via a high-pressure pipe. The steel rod has a water inlet chamber inside near the output end of the pneumatic drill. Multiple water spray holes are formed along the circumference of the peripheral wall of the water inlet chamber. All of the multiple water spray holes are located outside the equipment box. The water outlet of the water storage tank is connected to the inside of the pneumatic drill via a high-pressure pipe and is connected to the water inlet chamber.

[0016] The beneficial effects of adopting the above technical solution are: high-pressure water enters the water inlet chamber inside the steel rod and sprays out from the water spray hole on the side wall of the water inlet chamber. When the steel rod is drilling, it can form a circumferential atomized water curtain, reduce the dispersion of dust particles, increase the visibility range, and also cool down the steel rod.

[0017] Furthermore, the gas supply mechanism includes a gas storage tank, a controller, and an exciter. The gas storage tank is vertically arranged on the inner bottom plate of the equipment box. The controller is installed at the top gas outlet of the gas storage tank to control gas release. The gas output end of the controller is connected to the exciter, and the gas outlet end of the exciter is connected to the gas guide pipe.

[0018] The beneficial effects of adopting the above technical solution are: through the coordinated operation of the controller, exciter, and conduit, precise control of the entire process from gas storage and release to its action on the target object can be achieved. The controller precisely regulates the gas release parameters, and the exciter activates the gas energy, enabling the gas to act on the mountain as expected, thereby improving the accuracy of blasting.

[0019] Furthermore, the coil mechanism is detachably installed on the bottom plate inside the equipment box. The air guide pipe includes a first section air guide pipe, a middle section connecting air pipe, and a second section air guide pipe. The first section air guide pipe is connected to the air outlet end of the exciter. The middle section connecting air pipe is coiled on the coil mechanism and its first end is rotatably connected to the first section air guide pipe. The second section air guide pipe is placed inside the blasting nozzle ejection mechanism and its two ends are respectively connected to the middle section connecting air pipe and the blasting nozzle.

[0020] The beneficial effects of adopting the above technical solution are as follows: the gas guide tube is divided into a three-section structure, and its length can be flexibly adjusted to adapt to blast holes of different depths. The middle section connecting gas tube can be coiled on the coil mechanism, and the length of the middle section connecting gas tube can be replaced according to the actual needs. This avoids pipeline redundancy and prevents the blast nozzle from failing to reach the bottom of the hole due to insufficient pipeline, ensuring that the tube body always remains fully extended during blasting. The coil mechanism adopts a detachable installation method, which facilitates quick disassembly and maintenance. When it is necessary to inspect or replace the gas guide tube or the coil mechanism, it is not necessary to disassemble the entire equipment on a large scale. The coil mechanism can be operated independently, reducing maintenance difficulty and cost. At the same time, the segmented gas guide tube also facilitates segmented inspection and repair, improving maintenance efficiency.

[0021] Furthermore, the coil mechanism includes a drive motor, a coil shaft, and a rotating plate. The drive motor is mounted on the bottom plate inside the equipment box and arranged close to the gas storage tank. The output end of the drive motor is arranged along the axial direction of the gas storage tank. The coil shaft is drivenly connected to the output end of the drive motor. The coil shaft is hollow inside and open at the top. The rotating plate is coaxially mounted on the coil shaft and rotates with it. A bend is fixedly connected to the side wall of the section of the coil shaft located below the rotating plate. The other end of the bend passes through the rotating plate. One end of the middle section connecting gas pipe passes through the coil shaft and the bend and is wrapped around the outer side wall of the coil shaft.

[0022] The beneficial effects of adopting the above technical solution are: the coil shaft is hollow inside and open at the top, and the bend leads the middle section connecting gas pipe to the top of the rotating plate, which can ensure that the gas pipe is not twisted or knotted during the winding process, the gas delivery channel is always unobstructed, avoids gas pressure loss caused by pipe bending, and ensures stable gas pressure at the blasting nozzle.

[0023] Furthermore, the two ends of the middle connecting air tube are connected to the first section air tube and the second section air tube respectively via detachable connectors.

[0024] The beneficial effects of adopting the above technical solution are: the detachable connector makes the connection between the middle section connecting air tube and the first and second section air guide tubes more flexible. Operators can quickly disassemble or connect the air tube, which facilitates the adjustment of the length of the air guide tube or the replacement of damaged tube sections, improving the adaptability and maintenance efficiency of the equipment.

[0025] Furthermore, the blasting nozzle ejection mechanism includes a horizontal push rod and a slider. A partition is horizontally arranged inside the equipment box. The horizontal push rod is installed on the partition, and its output end is arranged facing the construction port. One end of the slider is fixed to the output end of the horizontal push rod. The horizontal push rod can drive the slider to slide on the partition. The tube sleeve is fixed to the top of the slider.

[0026] The beneficial effects of adopting the above technical solution are: the cooperation of the horizontal push rod and the slider can accurately push the sleeve and the second section of the gas guide pipe inside to the blast hole, ensuring that the blasting nozzle can accurately extend into the blast hole, so that the gas blasting energy can be fully applied to the mountain, improve the blasting effect, and also avoid the collision between the blasting nozzle and the hole wall, reducing the risk of equipment damage.

[0027] Furthermore, one end of the blasting nozzle is open and connected and fixed to the second section of the air guide pipe, and multiple air jet holes are provided on the peripheral wall of the blasting nozzle.

[0028] The beneficial effects of adopting the above technical solution are: one end of the blasting nozzle is open and connected to the second section of the gas guide pipe through multiple jet holes. When the gas is ejected at high speed from the jet holes, multiple impact points can be formed in the blasting hole, so that the blasting energy acts more concentratedly on the rock wall of the hole, improving the blasting efficiency. It is especially suitable for hard rock or scenarios that require precise blasting.

[0029] Furthermore, the radial snap-fit ​​assembly includes a mounting base, a pressing block, and a stop block. The mounting base is fixed to the end of the blasting nozzle away from its opening. The mounting base is hollow inside and has a pressing block mounting hole at one end away from the blasting nozzle. The pressing block is slidably mounted in the pressing block mounting hole along the axial direction of the mounting base. Multiple stop block mounting holes are spaced apart on the peripheral sidewall of the mounting base. Multiple stop blocks are slidably mounted in the stop block mounting holes along the radial direction of the mounting base. When the pressing block abuts against the inner end of the mountain hole, it can press the stop block to move radially away from the axis of the mounting base and snap onto the inner sidewall of the mountain hole. Electromagnets that can be magnetically connected to each other are embedded on the opposite sidewalls of the mounting base and the pressing block.

[0030] The beneficial effects of adopting the above technical solution are as follows: When the extrusion block abuts against the inner end of the mountain hole, the stop block moves radially outward through extrusion and is firmly locked onto the inner side wall of the mountain hole, effectively preventing the blasting nozzle from falling out of the blasting hole under the action of high-pressure gas, and ensuring the smooth progress of the blasting process; electromagnets that can be magnetically connected to each other are embedded on the opposite side walls of the mounting base and the extrusion block. When the extrusion block abuts against the inner end of the mountain hole, the electromagnets are magnetically attracted, further enhancing the connection stability between the extrusion block and the mounting base, and preventing the extrusion block from loosening due to vibration or gas impact during the blasting process.

Detailed Implementation

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] This utility model discloses an integrated device for drilling holes and gas blasting in mountains, comprising: a movable equipment box 1, a blasting hole drilling mechanism 2, a gas supply mechanism 3, a coil mechanism 4, and a blasting nozzle ejection mechanism 5. The equipment box 1 has a first side wall and a second side wall arranged opposite to each other. A pusher 11 is fixed to the first side wall, and a construction opening 12 is provided on the second side wall. The blasting hole drilling mechanism 2 is vertically and elliptably installed inside the equipment box 1 and close to the construction opening 12. The drilling part of the blasting hole drilling mechanism 2 can extend out of the construction opening 12 to drill holes in the mountain. The gas supply mechanism 3 is arranged inside the equipment box 1 and close to the pusher 11. Arrangement: The coil mechanism 4 is arranged inside the equipment box 1 and close to the gas supply mechanism 3. The gas output port of the gas supply mechanism 3 is connected to the gas guide pipe 31 and can be coiled on the coil mechanism 4. The blasting nozzle ejection mechanism 5 is installed at the top inside the equipment box 1, and its output end is arranged along the axial direction of the construction port 12. The top of the blasting nozzle ejection mechanism 5 is provided with a sleeve 51 arranged coaxially with the construction port 12. The gas guide pipe 31 is slidably assembled in the sleeve 51, and its outlet is connected to the blasting nozzle 6. One end of the blasting nozzle 6 abuts against the circumferential wall of the sleeve 51, and the other end is also provided with a radial clamping component 7 that can be clamped into the blasting hole in the mountain.

[0039] A specific embodiment of the blasting hole drilling mechanism 2 in this utility model includes an air compressor 21, a lifting push rod 22, a pneumatic drill 23, and a steel rod 24. The air compressor 21 is arranged at the bottom of the equipment box 1 and away from the second side wall of the equipment box 1. The lifting push rod 22 is installed on the inner bottom plate of the equipment box 1 and close to the second side wall of the equipment box 1, and its output end is fixed with a mounting platform. The pneumatic drill 23 is fixed on the mounting platform and its output end faces the second side wall of the equipment box 1. The input end of the pneumatic drill 23 is connected to the output end of the air compressor 21 through a high-pressure pipe. A trajectory hole is opened on the second side wall of the equipment box 1 corresponding to the lifting trajectory of the steel rod 24. The first end of the steel rod 24 is assembled to the output end of the pneumatic drill 23, and its second end is a conical tip that extends out of the trajectory hole. The high-frequency impact energy is concentrated, which can still efficiently break rocks in medium-hard or hard rock layers; at the same time, there are no high-speed rotating parts, so it is not easy to get stuck or break the rod. On-site maintenance only requires periodic replacement of the steel rod, which reduces the maintenance frequency and maintenance cost.

[0040] In the above embodiment, to reduce dust generated during drilling, the blasting hole drilling mechanism 2 also includes a water storage tank 25. The output end of the air compressor 21 is also connected to the water storage tank 25 via a high-pressure pipe. A water inlet chamber 241 is opened inside the steel rod 24 near the output end of the pneumatic drill 23. Multiple water spray holes are opened along the circumference of the peripheral wall of the water inlet chamber 241. The multiple water spray holes are all located outside the equipment box 1. The water outlet of the water storage tank 25 is connected to the interior of the pneumatic drill 23 via a high-pressure pipe and is connected to the water inlet chamber 241. High-pressure water enters the water inlet chamber 241 inside the steel rod 24 and is sprayed out from the water spray holes on the side wall of the water inlet chamber 241. When the steel rod 24 is drilling, a circumferential atomized water curtain can be formed, reducing dust particle dispersion, increasing the visibility range, and also cooling the steel rod 24.

[0041] In a specific embodiment of the gas supply mechanism 3 of this utility model, the gas supply mechanism 3 includes a gas storage tank 32, a controller 33, and an exciter 34. The gas storage tank 32 is vertically arranged on the inner bottom plate of the equipment box 1. The controller 33 is installed at the top gas outlet of the gas storage tank 32 to control gas release. The gas output end of the controller 33 is connected to the exciter 34, and the gas outlet end of the exciter 34 is connected to the gas guide pipe 31. Through the coordinated operation of the controller 33, the exciter 34, and the guide pipe 31, precise control of the entire process from gas storage and release to its action on the target object is achieved. The controller 33 precisely regulates the gas release parameters, and the exciter 34 activates the gas energy, enabling the gas to act on the mountain as expected, thus improving the accuracy of blasting.

[0042] In the above embodiment, the coil mechanism 4 is detachably installed on the bottom plate inside the equipment box 1. The air guide pipe 31 includes a first section air guide pipe 311, a middle section connecting air pipe 312, and a second section air guide pipe 313. The first section air guide pipe 311 is connected to the air outlet end of the exciter 34. The middle section connecting air pipe 312 is coiled on the coil mechanism 4 and its first end is rotatably connected to the first section air guide pipe 311. The second section air guide pipe 313 is placed inside the pipe sleeve 51 and its two ends are respectively connected to the middle section connecting air pipe 312 and the blasting nozzle 6. The gas guide tube 31 has a three-section structure, and its length can be flexibly adjusted to adapt to blast holes of different depths. The middle section connecting gas tube 312 can be coiled on the coil mechanism 4. The length of the middle section connecting gas tube 312 can be changed according to the actual needs, which avoids pipeline redundancy and prevents the blast nozzle from failing to reach the bottom of the hole due to insufficient pipeline, so that the tube body always remains fully extended during blasting. The coil mechanism 4 adopts a detachable installation method, which facilitates quick disassembly and maintenance. When the gas guide tube 31 or the coil mechanism 4 needs to be inspected or replaced, there is no need to disassemble the entire equipment on a large scale. The coil mechanism 4 can be operated independently, which reduces the difficulty and cost of maintenance. At the same time, the segmented gas guide tube 31 also facilitates segmented inspection and repair, improving maintenance efficiency.

[0043] In a specific embodiment of the coil mechanism 4 of this utility model, the coil mechanism 4 includes a drive motor 41, a coil shaft 42 and a rotating plate 43. The drive motor 41 is mounted on the bottom plate inside the equipment box 1 and arranged close to the gas storage tank 32. The output end of the drive motor 41 is arranged along the axial direction of the gas storage tank 32. The coil shaft 42 is connected to the output end of the drive motor 41. The coil shaft 42 is hollow inside and open at the top. The rotating plate 43 is coaxially mounted on the coil shaft 42 and rotates with it. A bend 421 is connected and fixed on the side wall of the pipe section below the rotating plate 43 of the coil shaft 42. The other end of the bend 421 passes through the rotating plate 43. One end of the gas pipe 312 in the middle section passes through the coil shaft 42 and the bend 421 and is wrapped around the outer side wall of the coil shaft 42. The coil shaft 42 is hollow inside and open at the top. The bend 421 leads the middle section connecting gas pipe 312 to the top of the rotating plate 43, which can ensure that the gas pipe is not twisted or knotted during the winding process, and the gas delivery channel is always unobstructed, avoiding gas pressure loss caused by pipe bending and ensuring stable gas pressure at the blasting nozzle 6.

[0044] In the above embodiment, to facilitate the replacement of the intermediate connecting air tube 312, both ends of the intermediate connecting air tube 312 are connected to the first section air guide tube 311 and the second section air guide tube 313 respectively via detachable connectors. The detachable connectors make the connection between the intermediate connecting air tube 312 and the first and second section air guide tubes more flexible. Operators can quickly disassemble or connect the air tubes, facilitating the adjustment of the length of the air guide tube 31 or the replacement of damaged sections, thus improving the adaptability and maintenance efficiency of the equipment.

[0045] In a specific embodiment of the blasting nozzle ejection mechanism 5 of this utility model, the blasting nozzle ejection mechanism 5 includes a horizontal push rod 52 and a slider 53. A partition is horizontally arranged inside the equipment box 1. The horizontal push rod 52 is mounted on the partition, with its output end facing the construction port 12. One end of the slider 53 is fixed to the output end of the horizontal push rod 52. The horizontal push rod 52 can drive the slider 53 to slide on the partition. The sleeve 51 is fixed to the top of the slider 53. The cooperation of the horizontal push rod 52 and the slider 53 can accurately push the sleeve 51 and the second section of the gas guide pipe 312 inside to the blasting hole 12, ensuring that the blasting nozzle 6 can accurately extend into the blasting hole, so that the gas blasting energy can fully act on the mountain, improve the blasting effect, and also avoid the collision between the blasting nozzle 6 and the hole wall, reducing the risk of equipment damage.

[0046] In the above embodiment, the blasting nozzle 6 is open at one end and connected and fixed to the second section of the gas guide pipe 313. Multiple air jet holes are provided on the peripheral sidewall of the blasting nozzle 6. Since the blasting nozzle 6 is open at one end and connected to the second section of the gas guide pipe 312 through multiple air jet holes, when gas is ejected at high speed from the air jet holes, multiple impact points can be formed within the blasting hole, allowing the blasting energy to act more concentrated on the rock wall of the hole, improving blasting efficiency. This is especially suitable for hard rock or scenarios requiring precise blasting.

[0047] In a specific embodiment of the radial snap-fit ​​assembly 7 of this utility model, the radial snap-fit ​​assembly 7 includes a mounting base 71, a pressing block 72, and a stop block 73. The mounting base 71 is fixed to the end of the blasting nozzle 6 away from its opening. The mounting base 71 is hollow inside and has a pressing block mounting hole at the end away from the blasting nozzle 6. The pressing block 72 is slidably installed in the pressing block mounting hole along the axial direction of the mounting base 71. Multiple stop block mounting holes are spaced apart on the peripheral side wall of the mounting base 71. Multiple stop blocks 73 are slidably installed in the stop block mounting holes along the radial direction of the mounting base 71. When the pressing block 72 abuts against the inner end of the mountain hole, the stop block 73 can be pressed to move radially away from the axis of the mounting base 71 and snap onto the inner side wall of the mountain hole. Electromagnets that can be magnetically connected to each other are embedded on the opposite side walls of the mounting base 71 and the pressing block 72. When the extrusion block abuts against the inner end of the borehole, the stop block moves radially outward through extrusion, firmly locking onto the inner wall of the borehole. This effectively prevents the blasting nozzle from falling out of the blasting hole under high-pressure gas, ensuring the smooth progress of the blasting process. Electromagnets that can be magnetically connected to each other are embedded on the opposite side walls of the mounting base and the extrusion block. When the extrusion block abuts against the inner end of the borehole, the electromagnets are magnetically attracted, further enhancing the connection stability between the extrusion block and the mounting base and preventing the extrusion block from loosening due to vibration or gas impact during the blasting process.

[0048] The working principle of this integrated device for drilling holes and gas blasting in mountains is as follows:

[0049] Manually or with a small tractor, the equipment box is pushed to the mountainside, with the drilling opening aligned with the area to be blasted. The drilling mechanism is then driven upwards, its output end extending from the drilling opening, and drilling is completed to the set depth. After drilling is complete, the equipment box is pulled out, removing the output end of the drilling mechanism from the blast hole, and then the drilling mechanism is returned to its original position. After drilling is complete, the blasting nozzle ejection mechanism is activated, pushing the gas guide pipe coaxially along the pipe sleeve until the blasting nozzle reaches the bottom of the hole. The radial locking assembly at the end of the blasting nozzle opens radially within the hole, conforming to the hole wall. An interference fit is formed to prevent springback, ensuring the blasting nozzle is locked inside the blast hole. Then, the coil mechanism is activated to unfold the gas guide pipe, simultaneously driving the equipment box away from the blast hole to a safe area. Once safety is ensured, the gas supply mechanism is activated to deliver high-pressure gas through the gas guide pipe into the blasting nozzle, completing the gas blasting of the mountain. After blasting, the radial locking assembly is released, the coil mechanism rotates in the opposite direction to retract the gas guide pipe, and the blasting nozzle ejection mechanism reverses its movement, retracting the blasting nozzle back into the equipment box. The entire box can then be moved to the next target hole location.

[0050] Therefore, by using this device, operators only need to operate from the pusher side, away from the orifice and the flying rock area, reducing the impact of falling rocks and dust on the human body. Drilling, pipe delivery, and air inflation are completed in one go, shortening working time, reducing the time for unfolding and storing the air pipe, and also reducing the time for equipment relocation, thus improving work efficiency.

Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
