Description

Technical Field

[0001] This invention belongs to the technical field of blasting engineering construction equipment, specifically relating to a device for inserting explosive cartridges into blasting holes in open-pit mines. Background Technology

[0002] In open-pit mining, blasting is an indispensable and crucial step, its effectiveness directly impacting production safety, efficiency, and cost. The quality of the explosive loading into the blast hole is one of the core factors affecting the blasting effect. Currently, open-pit mines commonly employ deep-hole bench blasting technology, which involves drilling, loading, packing, and detonation to break up the ore and rock. The loading process typically involves inserting multiple explosive cartridges sequentially into the bottom of the blast hole, ensuring close contact and correct order between the cartridges to guarantee effective propagation of the detonation wave and full release of explosive energy. Traditional loading methods rely primarily on manual operation, or with the assistance of some simple machinery, to place the cartridges into the hole one by one.

[0003] However, existing manual or semi-mechanical loading methods have many problems: First, each explosive cartridge needs to be processed individually and placed into the deep hole one by one, which takes a very long time, especially when the hole is deep or there are many explosive cartridges in a single hole; Second, the arrangement order of the explosive cartridges in the hole may be disordered due to operational errors, and gaps or overlaps may occur between the explosive cartridges, affecting the blasting effect; Third, manual direct contact with the explosive cartridges for loading may cause damage to the outer skin of the explosive cartridges or scattering of explosives due to friction and collision with the rough hole wall, and there may be unexpected hazards caused by improper operation during the process. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide an explosive cartridge insertion device for blasting holes in open-pit mines, which solves the technical problems of low efficiency, easy damage to explosive cartridges, and easy disorder of the arrangement order in the hole caused by traditional manual single-cartridge loading.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention includes a walking mechanism and a pill insertion mechanism.

The two ends of the guide rail are respectively mounted on the front and rear support seats. The pushing movable seat is moved on the guide rail by a motor. The rear end of the insertion tube is connected to the pushing movable seat. The moving base is fixedly connected. The guiding assembly includes a guide cylinder, which is fixed to one end of the guide rail near the front support. The front end of the insertion tube is slidably disposed in the guide cylinder. The elastic retaining ring is fixed to the front end of the insertion tube. The inner side of the elastic retaining ring is provided with a perforated elastic membrane. The explosive cartridge insertion mechanism is vertically arranged so that the insertion tube is vertically positioned. Several explosive cartridges are placed sequentially in the insertion tube and temporarily blocked by the elastic retaining ring. The traveling mechanism is used to move the insertion tube above the blast hole. The pushing moving seat inserts the insertion tube into the bottom of the blast hole. The abutting component is used to abut the uppermost explosive cartridge in the insertion tube. As the pushing moving seat moves upward, the explosive cartridge is abutted into the blast hole by the abutting component.

[0006] Optionally, a rotating mechanism is also included, which includes a bottom beam, a first leg, and a rotating drive hydraulic cylinder.

The rotating drive hydraulic cylinder drives the cantilever beam to rotate and switch between a vertical state and a horizontal state.

[0007] Optionally, the guide rail is rotatably mounted on the front and rear support seats by a motor drive. The insertion assembly includes a guide rail, an insertion movable seat, a connecting crank, and a telescopic abutment. The two ends of the guide rail are fixedly mounted on the front and rear support seats, respectively. The extension direction of the guide rail is the same as the extension direction of the insertion tube. The insertion tube is located between the guide rail and the cantilever beam. The insertion movable seat is movably mounted along the guide rail. One end of the connecting crank is fixedly connected to the outside of the insertion movable seat, and the other end is fixedly connected to the tail end of the telescopic abutment. The extension direction of the telescopic abutment is the same as that of the insertion tube. A groove is opened on the outside of the insertion tube for the telescopic abutment to pass through. When the guide rail is rotated to the insertion hole position, the telescopic abutment extends into the insertion tube from the groove.

[0008] Optionally, the drug cartridge insertion mechanism further includes a limiting component, which includes an upper limit seat. The upper limit seat is fixed to the outside of the suspension beam. When the insertion tube is in the insertion hole position, the upper limit seat blocks the outside of the insertion tube.

[0009] Optionally, the guide assembly further includes a plurality of balls, which are rotatably disposed inside the guide cylinder, with portions of the balls protruding from the inside of the guide cylinder for support on the outside of the insertion tube.

[0010] Optionally, the rotating mechanism further includes a second leg fixed to the rear end of the bottom beam. When the rotating drive hydraulic cylinder drives the bottom beam to a lateral position, the second leg supports the bottom side of the cantilever beam.

[0011] Optionally, a feeding mechanism is also included, comprising a standing assembly and a pill loading assembly. The standing assembly includes a support frame and a standing platform, and the pill loading assembly includes an arc-shaped base. The support frame is fixedly connected to the upper platform, and the standing platform and the arc-shaped base are fixed on the support frame. When the suspension beam is horizontal, the guide rail is rotated, and the insertion tube is coaxial with the arc-shaped base. The arc-shaped base is located at the tail end of the coaxial insertion tube, and the standing platform is located outside the arc-shaped base and lower than the arc-shaped base.

[0012] Optionally, the drug roll inlet assembly further includes a pusher cylinder, a transmission crank, and a pusher plate. The pusher plate is slidably disposed on the arc-shaped base. The pusher cylinder is fixed to the bottom side of the standing platform. The transmission crank is connected between the pusher plate and the output end of the pusher cylinder. The pusher cylinder drives the pusher plate to reciprocate on the arc-shaped base.

[0013] Optionally, there are multiple rotating mechanisms and drug cartridge insertion mechanisms, with the rotating mechanisms arranged and installed on the upper platform.

[0014] Optionally, an alignment mechanism is also included, which includes a middle platform, a lower platform, a first push cylinder, and a second push cylinder; the lower platform is fixedly connected to the traveling mechanism, the middle platform is horizontally linearly movable on the surface of the lower platform, the first push cylinder is fixed on the lower platform and pushes the middle platform to move, the upper platform is linearly movable on the surface of the middle platform, the second push cylinder is fixed on the middle platform and pushes the upper platform to move, and the moving direction of the upper platform is perpendicular to the moving direction of the middle platform.

[0015] The beneficial effects of this invention are as follows: 1. A tube capable of accommodating all explosive charges at once is used, and mechanical power is used to insert it into the blast hole in one go and then push it in. This "whole-to-hole, sequential push-out" operation mode replaces the inefficient traditional method of manually inserting single explosive charges, greatly improving efficiency. At the same time, arranging the explosive charges outside the blast hole ensures that the order of the charges is correct, avoiding the arrangement errors that may occur when directly inserting them into the blast hole, and ensuring the reliability and consistency of the blasting effect.

[0016] 2. The explosive cartridge is always protected by the insertion tube throughout the entire loading process, which effectively avoids direct scraping and collision with the rough hole wall. It also reduces the risk of damage to the outer skin of the explosive cartridge and scattering of explosives that may be caused by manual throwing, friction and other operations, thereby improving operational safety and ensuring the explosiveness of the explosive.

[0022] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0023] This invention provides a device for inserting explosive cartridges into blasting holes in open-pit mines, such as... Figure 1As shown, the device includes a walking mechanism 1, a control mechanism 2, and a cartridge insertion mechanism 3. The control mechanism 2 includes a control cabin 21 and a power cabin 22. The power cabin 22 provides hydraulic, electrical, and power supplies to the entire device. The control cabin 21 is used for the operator to ride in and control the entire device. The walking mechanism 1 is used to drive the entire device to move and position stably and accurately on complex mining surfaces. Its chassis is a tracked structure. The walking mechanism 1 includes an upper platform 11, and the cartridge insertion mechanism 3 is mounted on the upper platform 11. Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the drug cartridge insertion mechanism 3 includes a supporting component 31, a pushing component, a guiding component 33, and an abutting component 34. The supporting component 31 includes a suspension beam 311, a front support 312, and a rear support 313. The front support 312 and the rear support 313 are respectively fixed to both ends of one side of the suspension beam 311. The pushing component includes a guide rail 321, a pushing movable seat 322, an insertion tube 323, and an elastic retaining ring 324. The two ends of the guide rail 321 are respectively mounted on the front support 312 and the rear support 313. The push-in movable seat 322 is moved and mounted on the guide rail 321 by a motor driven by a motor, preferably a servo motor or a stepper motor, coupled by a gear and rack mechanism to ensure the accuracy and stability of the stroke control of the push-in movable seat 322. The rear end of the insertion tube 323 is fixedly connected to the push-in movable seat 322. The length of the insertion tube 323 is slightly larger than the depth of the blast hole, and the inner diameter matches the outer diameter of the explosive cartridge to be inserted, so that it can accommodate all the explosive cartridges required for single-hole blasting at one time. The guide assembly 33 includes a guide cylinder 331. The insertion tube 323 is fixed to one end of the guide rail 321 near the front support 312. The front end of the insertion tube 323 is slidably disposed inside the guide cylinder 331. The elastic retaining ring 324 is fixed to the front end of the insertion tube 323. The inner side of the elastic retaining ring 324 is provided with a perforated elastic membrane. The elastic membrane is made of wear-resistant elastic materials such as polyurethane or silicone. A circular hole smaller than the outer diameter of the medication roll is opened in the center of the membrane. Its function is to temporarily support all the medication rolls inside during the insertion of the insertion tube 323 to prevent them from falling out. When the medication roll is pushed upward into the hole, it can be held in place by the medication roll. The roll is easily opened, with minimal resistance to the passage of the explosive roll. The explosive roll insertion mechanism 3 is vertically positioned, allowing the insertion tube 323 to stand vertically. Several explosive rolls are placed sequentially inside the insertion tube 323 and temporarily blocked by the elastic retaining ring 324. The traveling mechanism 1 is used to move the insertion tube 323 above the blast hole. The pushing and moving seat 322 inserts the insertion tube 323 into the bottom of the blast hole. The abutting component 34 is used to abut the uppermost explosive roll inside the insertion tube 323. As the pushing and moving seat 322 moves upward, the explosive roll is abutted into the blast hole by the abutting component 34.

[0024] The mechanical operation of this device is as follows: First, the operator or automatic loading system loads all the explosive cartridges required for a single hole into the vertical insertion tube 323 in sequence, with the bottom cartridge temporarily supported by the elastic retaining ring 324 at the front end of the insertion tube 323. Then, the traveling mechanism 1 moves, positioning the device directly above the target blast hole. Next, the pushing component is activated, and the pushing moving seat 322 drives the fully loaded insertion tube 323 downwards quickly and stably along the guide rail 321 until the entire insertion tube 323 is inserted into the bottom of the blast hole. At this point, all explosive cartridges have been delivered to the bottom of the hole along with the insertion tube 323. Then, the abutting component 34 actuates, its abutting rod extending horizontally into the upper end of the insertion tube 323, pressing down the top of the uppermost explosive cartridge. Afterwards, the pushing moving seat 322 begins to move in the opposite direction, driving the insertion tube 323 upwards at a uniform speed to exit the blast hole. During this process, as the push rod of the insertion component 34 remains in a fixed position pressing down on the uppermost explosive cartridge, the insertion tube 323 moves upward while the explosive cartridges are blocked by the push rod and remain relatively in place, thus being "peeled off" one by one and neatly pushed into the hole. When the insertion tube 323 is completely withdrawn from the blast hole, all the explosive cartridges have been accurately and tightly arranged at the designated position at the bottom of the hole.

[0025] Compared to traditional manual loading methods, this invention offers the following significant advantages: 1. By employing an insertion tube 323 capable of accommodating all explosive cartridges at once, and utilizing mechanical power to insert it into the blast hole and then push it in, this "overall lowering and sequential pushing" operation mode replaces the inefficient traditional method of manually placing individual explosive cartridges, greatly improving efficiency. Simultaneously, the arrangement of explosive cartridges outside the blast hole ensures correct arrangement order, avoiding potential errors that may occur when directly placing them into the blast hole, thus guaranteeing the reliability and consistency of the blasting effect. 2. Throughout the loading process, the explosive cartridges remain protected by the insertion tube 323, effectively preventing direct scraping and collision with the rough hole wall. This also reduces the risk of damage to the cartridge casing and explosive scattering caused by manual throwing or friction, improving operational safety and ensuring the explosiveness of the explosive.

[0026] In further proposals, such as Figure 3 and Figure 4As shown, the present invention also includes a rotating mechanism 4, which is used to realize the overall posture change of the drug cartridge insertion mechanism 3. Specifically, the rotating mechanism 4 includes a base beam 41, a first leg 42, and a rotating drive hydraulic cylinder 43. The base beam 41 is rigidly fixed to the top surface of the upper platform 11 of the traveling mechanism 1 by high-strength bolts or welding, providing a stable foundation for the entire rotating mechanism 4. The bottom end of the first leg 42 is fixedly connected to the front end of the base beam 41 by a pin, and its top end is hinged to the bottom side end of the suspension beam 311 by a wear-resistant pin, so as to ensure the stability and load-bearing capacity of the suspension beam 311 during rotation. The bottom end of the rotating drive hydraulic cylinder 43 is hinged to the rear end of the base beam 41 by a pin, and its top end is also hinged to the rear end of the base beam 41 by a wear-resistant pin. The rotating drive hydraulic cylinder 43 is connected to the bottom center of the suspension beam 311 via a pin. It is preferably a double-acting hydraulic cylinder with a built-in displacement sensor and hydraulic lock to ensure the accuracy of position control and reliable self-locking at any position, preventing accidental retraction or slippage under load. The extension and retraction of the rotating drive hydraulic cylinder 43 can drive the suspension beam 311, thereby driving the entire cartridge insertion mechanism 3 to smoothly and controllably switch between the vertical working state (the insertion tube 323 is perpendicular to the ground, ready to be inserted into the blast hole below) and the horizontal state (the insertion tube 323 is parallel to the ground, ready to be filled or in the equipment transfer and transportation posture).

[0027] This design uses a hydraulic cylinder to switch the insertion tube 323 between horizontal and vertical positions. When the insertion tube 323 is placed horizontally, its height is significantly reduced, allowing operators to easily and accurately push multiple explosive cartridges horizontally into the tube from its rear end. This avoids the risks of collisions, impacts, cartridge deformation, or separation of explosives from their packaging caused by free fall of cartridges in a vertical position. After all cartridges are inserted, the insertion tube 323 slowly and smoothly tilts to a vertical position along with the cantilever beam 311. During this process, the cartridges slide gently and orderly under gravity and are tightly arranged at the elastic retaining ring 324 at the bottom of the insertion tube 323. This controlled movement effectively prevents the cartridges from becoming disordered, stuck, or damaged within the tube, ensuring the correct loading density and sequence. Furthermore, when the cartridge insertion mechanism 3 is laid down to a horizontal position, the overall passage height of the equipment is reduced, allowing the device to safely and smoothly pass through height-restricted areas, improving the equipment's mobility and relocation efficiency in complex mining environments. The rotation function enables the device to handle not only vertically downward blasting holes, but also blasting holes with a certain tilt angle by adjusting the rotation angle, thus enhancing the equipment's adaptability to different engineering needs.

[0028] In further proposals, such as Figure 4 and Figure 5As shown, the guide rail 321 is rotatably mounted on the front support 312 and the rear support 313 by a motor drive. This means that the guide rail 321 not only serves as a linear motion track for pushing in the movable seat 322, but it can also rotate around its axis, thereby driving the entire insertion tube 323 to rotate. The insertion assembly 34 includes a guide rail 341, a lead screw 345, an insertion movable seat 342, a connecting crank 343, and a telescopic abutment 344. The two ends of the guide rail 341 are rigidly fixed to the front support 312 and the rear support 313 by welding, respectively. The lead screw 345 is rotatably mounted on the front support 312 by a motor drive. On the front support 312 and rear support 313, a through hole is provided in the middle section of the front support 312 for the insertion tube 323 to pass through. The extension direction of the guide rail 341 is parallel to the extension direction of the insertion tube 323. The insertion tube 323 is located between the guide rail 341 and the cantilever beam 311. The abutting moving seat 342 is movable along the guide rail 341. The abutting moving seat 342 is threadedly connected to the lead screw 345. Under the drive of the motor, the abutting moving seat 342 moves linearly back and forth along the guide rail 341. One end of the connecting crank 343 is fixedly connected to the outside of the abutting moving seat 342, and the other end is fixedly connected to the tail end of the telescopic abutment 344. The telescopic abutment 344 is driven to extend and retract by the pushing electric cylinder 522. The telescopic abutment 344 extends in the same direction as the insertion tube 323. The outside of the insertion tube 323 is provided with a groove 323a for the telescopic abutment 344 to pass into the inside. When the guide rail 321 is rotated to the insertion hole position, the telescopic abutment 344 extends from the groove 323a into the insertion tube 323 and is directly aligned with the uppermost medicine roll.

[0029] In this structure, after the drug cartridge is loaded, the guide rail 321 rotary motor starts, driving the guide rail 321 and the fixed insertion tube 323 to rotate together. This rotation causes the groove 323a on the outside of the insertion tube 323 to align with the telescopic abutment 344. Subsequently, the telescopic abutment 344 extends into the insertion tube 323 and is coaxial with the insertion tube 323. At this time, the motor of the pushing assembly drives the pushing moving seat 322 and the insertion tube 323 fixed thereto to insert downward into the blast hole. After insertion, the abutment moving seat 342 drives the entire abutment assembly 34 to move downward. The telescopic abutment 344 is driven by the electric cylinder to extend and abut against the top of the drug cartridge at the upper end of the insertion tube 323. At this time, the telescopic abutment 344 remains in a fixed position. As the insertion tube 323 moves upward with the pushing moving seat 322, the drug cartridges are blocked by the telescopic abutment 344, thus being "peeled" one by one and neatly placed in the hole. After the tube is retracted, the telescopic abutment 344 retracts and abuts against the movable seat 342, causing the telescopic abutment 344 to move back. The guide rail 321 can then rotate and reset to the initial loading angle, preparing for the next work cycle.

[0030] This design significantly shortens the overall length of the equipment through spatial layout. By employing a clever rotating slot design, the insertion component is changed from the traditional, space-consuming, coaxially aligned arrangement with the insertion tube 323 to a radially lateral arrangement. This eliminates the need for the insertion assembly 34 to be installed directly behind the insertion tube 323, saving axial space and effectively reducing the overall length of the entire medication insertion mechanism 3. This results in a more compact structure, prevents equipment wobbling, and improves equipment stability.

[0031] In further proposals, such as Figure 3 and Figure 4 As shown, the drug cartridge insertion mechanism 3 also includes a limiting component, which includes an upper limit seat 351. The upper limit seat 351 is fixed to the outside of the suspension beam 311. When the insertion tube 323 is in the insertion hole position, the upper limit seat 351 blocks the outside of the insertion tube 323.

[0032] In further proposals, such as Figure 3 As shown, the guide assembly 33 also includes a plurality of balls 332, which are rotatably disposed inside the guide cylinder 331. Part of the balls 332 protrude from the inside of the guide cylinder 331 and are used to support the outside of the insertion tube 323.

[0033] When the insertion tube 323 moves up and down linearly under the drive of the motor, its outer wall comes into direct contact with the exposed balls 332 inside the guide cylinder 331. Traditional sliding friction is transformed into rolling friction. This structure provides the insertion tube 323 with high-precision, low-friction, and high-stability linear guidance.

[0034] In further proposals, such as Figure 3 and Figure 4 As shown, the rotating mechanism 4 also includes a second leg 44, which is fixed to the rear end of the bottom beam 41. When the rotating drive hydraulic cylinder 43 drives the bottom beam 41 to a lateral state, the second leg 44 supports the bottom side of the cantilever beam 311.

[0035] In further proposals, such as Figure 1 and Figure 2As shown, it also includes a feeding mechanism 5, which includes a standing assembly 51 and a pill loading assembly 52. ​​The standing assembly 51 includes a support frame 511 and a standing platform 512. The pill loading assembly 52 includes an arc-shaped base 521. The support frame 511 is fixed to the upper platform 11 of the traveling mechanism 1 by high-strength bolts or welding, providing a stable support foundation for the entire feeding mechanism 5. The arc-shaped base 521 is also fixed to the support frame 511, and its inner surface is set as a smooth concave arc surface to ensure that the pills can slide in smoothly and avoid surface damage. The standing platform 512 is made of anti-slip grating or patterned steel plate. Correspondingly, a lower limit seat 352 is fixedly installed on one side of the suspension beam 311. After the guide rail 321 is rotated to move the insertion tube 323 away from the insertion component 34, it is finally blocked by the lower limit seat 352. When the cantilever beam 311 is horizontal, the insertion tube 323 blocked by the lower limit seat 352 is coaxial with the arc-shaped base 521, and the arc-shaped base 521 is located at the tail end of the coaxial insertion tube 323. The standing platform 512 is located outside the arc-shaped base 521 and lower than the arc-shaped base 521, which makes it convenient for the operator to take the medicine roll from the material box or conveying structure next to him, and also allows him to easily place the medicine roll horizontally on the arc-shaped base 521 and push it into the insertion tube 323. The area of ​​the standing platform 512 should meet the needs of an operator to stand safely and comfortably. Protective railings and kickboards should be set around it to comply with the mine safety regulations.

[0036] This structure provides a safe, efficient, and ergonomic lateral loading method: a dedicated standing platform 512 provides the operator with a stable, safe, and comfortable working position; the curved base 521 allows the explosive cartridges to be smoothly and accurately centered and slid horizontally into the insertion tube 323. This structure greatly simplifies the operation, reduces loading difficulty, increases loading speed, and effectively protects the integrity of the explosive cartridges and ensures their arrangement order. The horizontal loading method avoids the impact and collision that may occur if the explosive cartridges fall directly under gravity. The smooth guidance of the curved base 521 maximizes the protection of the explosive cartridge outer skin from damage and prevents the explosive from scattering. At the same time, the sequential horizontal loading method ensures that the arrangement order of the explosive cartridges in the insertion tube 323 is consistent with the design requirements, avoiding confusion.

[0037] In further proposals, such as Figure 2 As shown, the drug roll inlet assembly 52 also includes a pushing cylinder 522, a transmission crank 523, and a push plate 524, which are used to automatically push the drug roll from the arc-shaped base 521 to the horizontal insertion tube 323. The push plate 524 is slidably disposed on the arc-shaped base 521. The pushing cylinder 522 is fixed to the bottom side of the standing platform 512. The transmission crank 523 is connected between the push plate 524 and the output end of the pushing cylinder 522. The pushing cylinder 522 drives the push plate 524 to reciprocate on the arc-shaped base 521.

[0038] This solution automates the loading of medicine rolls by replacing manual pushing with an electric cylinder. The pushing speed, stroke, and force remain constant, eliminating problems such as uneven force and inconsistent rhythm that may occur with manual operation. This makes the loading action of each medicine roll consistent and repeatable, improving the stability of the loading rhythm and overall efficiency.

[0039] In further proposals, such as Figure 1 As shown, there are two rotating mechanisms 4 and drug roll insertion mechanisms 3, and the rotating mechanisms 4 are arranged and installed on the upper platform 11.

[0040] This invention employs a parallel layout of a dual-rotation mechanism 4 and a charge insertion mechanism 3. Through parallel operation and process optimization, it significantly improves the continuity and efficiency of charge loading operations in open-pit mine blasting holes, with the two mechanisms working alternately. When mechanism one performs the complete loading cycle of "positioning-insertion-push-reset," mechanism two can simultaneously prepare for "rotating to the loading position-receiving charge loading." This means that while one mechanism completes its operation and moves to the next hole, the other mechanism is already fully loaded with charge and ready to go. The equipment only needs to move to the next blasting hole, and the ready mechanism can immediately begin the insertion operation, eliminating the inherent "loading waiting time" in single-mechanism designs and maximizing the effective working time of the equipment.

[0041] In further proposals, such as Figure 1 and Figure 7 As shown, it also includes an alignment mechanism 6, used to compensate for deviations after the initial positioning of the traveling mechanism 1, ensuring that the axis of the insertion tube 323 is precisely aligned with the axis of the blast hole. It employs a double-layer cross slide structure: the alignment mechanism 6 includes a middle platform 61, a lower platform 62, a first push cylinder 63, and a second push cylinder 64; the lower platform 62 is fixedly connected to the traveling mechanism 1, and its surface is provided with a finely ground hardened guide rail 321. The middle platform 61 is horizontally linearly movable on the surface of the lower platform 62, and its surface is also provided with a finely ground hardened guide rail 321. The first push cylinder 63 is fixed on... The lower platform 62 pushes the middle platform 61 to move, and the upper platform 11 is linearly moved on the surface of the middle platform 61. The second pushing cylinder 64 is fixed on the middle platform 61 and pushes the upper platform 11 to move. The moving direction of the upper platform 11 is perpendicular to the moving direction of the middle platform 61. After the traveling mechanism 1 moves to the position of the blast hole, the horizontal direction of the insertion tube 323 is adjusted so that the insertion tube 323 coincides with the blast hole. This structure reduces the overall adjustment movement of the traveling mechanism and shortens the preparation time between stopping and starting insertion at each hole position.
