Description

Technical Field

[0001] This invention belongs to the field of blasting construction equipment, and particularly relates to a detonator loading device and method for blasting construction. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] During tunnel construction, the tunnel excavation is mostly carried out using the drill-and-blast method. Multiple blast holes are drilled on the tunnel face according to the construction requirements. Then, detonators are manually loaded into the blast holes, and the detonator leads are connected to form a network for detonation. The shock wave generated by the explosion of the explosives loaded into the blast holes and the work done by the explosives break the rock mass within the tunnel area.

[0004] Currently, when loading detonators into blast holes, construction workers often need to carry a large number of detonators and manually load them one by one. After loading, in order to improve the blasting effect, each blast hole also needs to be sealed with stemming material. Therefore, the inventor found that in the detonator loading operation, especially when there are a large number of blast holes on the working face, the labor intensity of construction workers is high, and the process of handling detonators and stemming material cannot be carried out continuously, which makes the manual operation of loading detonators and stemming material into each blast hole inefficient. Summary of the Invention

[0005] In order to solve the technical problems existing in the background art, the present invention provides a detonator loading device and method for blasting construction, which can realize the continuous batch picking and loading of detonators and drilling mud. Moreover, during the entire detonator loading operation, the construction personnel do not need to carry the detonators and drilling mud themselves. Compared with the traditional operation of filling the blast holes one by one by hand with detonators and drilling mud, the operation efficiency is improved.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The first aspect of the present invention provides a detonator loading device for blasting operations.

[0008] A detonator loading device for blasting operations includes: an installation platform, a sector-shaped turntable, a detonator placement cylinder, a stemming material placement cylinder, a rotating mechanism, and a push rod;

[0009] The top center of the fan-shaped turntable is provided with a U-shaped placement groove, and the front side of the fan-shaped turntable is provided with a U-shaped guide groove. The U-shaped placement groove and the U-shaped guide groove are arranged opposite each other, and the bottom of the U-shaped guide groove is fixed on the installation platform.

[0010] The detonator placement cylinder and the clay placement cylinder are symmetrically arranged along the center of the U-shaped placement groove, and are both fixed on the installation platform and inclined above the fan-shaped turntable; the bottom of the detonator placement cylinder and the clay placement cylinder are slidably connected to the top surface of the fan-shaped turntable.

[0011] The push rod is horizontally positioned on the rear side of the fan-shaped turntable, with the push rod facing the U-shaped placement groove. By moving the push rod horizontally, the detonator that falls from the detonator placement cylinder into the U-shaped placement groove is pushed into the borehole, and the clay that falls from the clay placement cylinder into the U-shaped placement groove is pushed into the borehole opening to seal the detonator.

[0012] The rotating mechanism is mounted on the installation platform. The output end of the rotating mechanism is connected to the fan-shaped turntable, which is used to drive the fan-shaped turntable to rotate vertically and circumferentially to switch the position of the U-shaped placement slot, thereby realizing the process of continuous batch loading of detonators and drilling mud.

[0013] In one embodiment, both the detonator placement cylinder and the clay placement cylinder are provided with inclined platforms at their bottom outlets, and the inclined surfaces of each inclined platform face the U-shaped guide groove.

[0014] In one embodiment, the push rod is connected to a moving mechanism, which is mounted on a mounting platform and is used to drive the push rod to move horizontally.

[0015] In one embodiment, the moving mechanism includes a horizontally arranged tube body, the bottom of which is fixed to an installation platform. The push rod is slidably fitted into the tube body. Guide slots are provided on both sides of the tube body along its length. A slide rod is slidably fitted into each guide slot. One end of each slide rod extends into the tube body and is fixed to the side wall of the push rod, while the other end of each slide rod extends out of the tube body.

[0016] In one embodiment, the push rod is provided with a telescopic rod assembly and a T-shaped mounting groove on the side wall facing the U-shaped placement groove. The telescopic rod assembly includes a T-shaped rod, which is slidably fitted into the T-shaped mounting groove. An electromagnet is fixed on the groove wall of the U-shaped placement groove facing the large end of the T-shaped rod. An iron block is embedded and fixed on the side wall of the large end of the T-shaped rod facing the electromagnet. Multiple horizontally arranged return springs are connected to the side wall of the large end of the T-shaped rod facing away from the electromagnet. The other end of each return spring is connected to the inner wall of the T-shaped mounting groove.

[0017] In one embodiment, the rotating mechanism includes a mounting block, a slider, an arc spring, a first limiting block, and a gripping rod;

[0018] The mounting block is vertically positioned on the rear side of the fan-shaped turntable, and its bottom is fixed to the mounting platform. The top of the mounting block is lower than the U-shaped placement groove, and an arc-shaped mounting slot is provided through the side wall of the mounting block. The arc-shaped mounting slot is concentrically positioned with the fan-shaped turntable.

[0019] The slider is slidably mounted in the arc-shaped mounting slot; the arc-shaped springs are set in the arc-shaped mounting slot and symmetrically arranged on both sides of the slider; one end of each arc-shaped spring is connected to the slider, and the other end of each arc-shaped spring is connected to the inner wall of the arc-shaped mounting slot.

[0020] The mounting block is provided with first limiting blocks on the front and rear sides respectively. The first limiting blocks are fixed to the front and rear side walls of the slider respectively. The limiting block located on the front side of the mounting block is fixedly connected to the rear side wall of the fan-shaped turntable.

[0021] The grip rod is horizontally fixed to the first limiting block located on the rear side of the mounting block.

[0022] In one embodiment, a stop bar is fixed on the rear side wall of the mounting block. The stop bar is located directly below the U-shaped placement groove, and the height of the stop bar is higher than the top height of the mounting block. Inclined second limiting blocks are fixed on both sides of the top of the mounting block, and the second limiting blocks are respectively positioned directly below the detonator placement cylinder and the clay placement cylinder.

[0023] In one implementation, the installation platform is mounted on top of the lifting platform.

[0024] In one embodiment, the installation platform is mounted on top of the lifting platform, and a traveling mechanism is provided at the bottom of the lifting platform.

[0025] In one embodiment, the installation platform is a rectangular frame, and a storage tank is provided inside the installation platform. The storage tank is divided into a detonator storage area and a clay storage area by a partition.

[0026] A second aspect of the present invention provides a detonator loading method using the detonator loading device for blasting construction as described above.

[0027] A detonator loading method using the detonator loading device for blasting operations as described above, comprising:

[0028] When the U-shaped placement trough is between the detonator placement cylinder and the gun clay placement cylinder, the fan-shaped turntable blocks the bottom of the detonator placement cylinder and the gun clay placement cylinder, thereby temporarily storing the detonator and gun clay.

[0029] When loading, align the U-shaped guide groove with the borehole. First, control the fan-shaped turntable to rotate counterclockwise, so that the U-shaped placement groove rotates to be directly below the detonator placement tube. At this time, the detonator in the detonator placement tube will fall into the U-shaped placement groove. Then, rotate the fan-shaped turntable clockwise so that the U-shaped placement groove is located between the detonator placement tube and the clay placement tube, and is directly opposite the U-shaped guide groove. At this time, use the push rod to push the detonator in the U-shaped placement groove into the U-shaped guide groove. Then, use the push rod to push the detonator in the U-shaped guide groove into the borehole. Finally, remove the push rod from the U-shaped guide groove and the U-shaped placement groove.

[0030] Next, control the fan-shaped turntable to rotate clockwise, so that the U-shaped placement groove rotates to be directly below the clay placement cylinder. At this time, the clay in the clay placement cylinder will fall into the U-shaped placement groove. Then, rotate the fan-shaped turntable counterclockwise so that the U-shaped placement groove is located between the detonator placement cylinder and the clay placement cylinder, and is directly opposite the U-shaped guide groove. At this time, use the push rod to push the clay in the U-shaped placement groove into the U-shaped guide groove. Then use the push rod to push the clay in the U-shaped guide groove to the borehole opening to seal the detonator. Finally, make the push rod move backward out of the U-shaped guide groove and the U-shaped placement groove, thus completing the entire process of loading a detonator. The same process is used to load the remaining barrels.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] This invention uses a rotating mechanism to drive a fan-shaped turntable to switch the position of the U-shaped placement slot. The U-shaped placement slot is used to complete the process of taking detonators and taking drilling mud, thereby realizing the continuous batch filling of detonators and drilling mud. Moreover, during the entire detonator filling operation, the construction personnel do not need to carry detonators and drilling mud themselves. Compared with the traditional operation of filling blast holes one by one by hand with detonators and drilling mud, the operation efficiency is improved.

[0043] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0044] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0045] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0046] This embodiment provides a detonator loading device for blasting operations, such as... Figure 1 As shown, it includes a lifting platform 1, an installation platform 2, a fan-shaped turntable 3, a detonator placement cylinder 41, a clay placement cylinder 42, a rotating mechanism, a push rod 5, and a moving mechanism.

[0047] like Figure 2 and Figure 3 As shown, in order to support and protect construction personnel, the installation platform 2 is rectangular. In order to store more detonators and drilling mud to replenish detonators into the detonator placement cylinder 41 and drilling mud into the drilling mud placement cylinder 42, a storage tank 21 is provided inside the installation platform 2. The inside of the storage tank 21 is divided into a detonator storage area 23 and a drilling mud storage area 24 by a partition 22.

[0048] The bottom of the lifting platform 1 is equipped with a traveling mechanism; the lifting platform 1 can be a hydraulic lifting machine.

[0049] In order to maintain stability when traveling on uneven roads, the walking mechanism is a tracked chassis, and the bottom of the hydraulic lift is connected to the tracked chassis.

[0050] In order to facilitate movement to various blast holes during detonator loading, a rotary table 9 is connected between the tracked chassis and the hydraulic lift. The rotary table 9 can drive the hydraulic lift mounting platform 2 to rotate horizontally. When the tracked chassis is not convenient to turn, the auxiliary mounting platform 2 rotates to face the blast hole for detonator loading.

[0051] The installation platform 2 is set on top of the lifting platform 1; the fan-shaped turntable 3 is set vertically, and a U-shaped placement groove 31 is provided at the center of the top of the fan-shaped turntable 3. A U-shaped guide groove 32 is provided on the front side of the fan-shaped turntable 3. The U-shaped placement groove 31 and the U-shaped guide groove 32 are set opposite each other. The bottom of the U-shaped guide groove 32 is fixed to the installation platform 2 by a positioning rod 33; the detonator placement cylinder 41 is set at an angle above the fan-shaped turntable 3 and is located on one side of the U-shaped placement groove 31. The bottom of the detonator placement cylinder 41 is slidably connected to the top surface of the fan-shaped turntable 3. The detonator placement cylinder 41 is fixed to the bottom of the installation platform 2 by a fixing bracket; the clay placement cylinder 42 is inclinedly set above the fan-shaped turntable 3 and symmetrically arranged with the detonator placement cylinder 41 along the center of the U-shaped placement groove 31. The bottom of the clay placement cylinder 42 is slidably connected to the top surface of the fan-shaped turntable 3. The clay placement cylinder 42 is fixed to the inner bottom surface of the mounting platform 2 by a fixing frame. The rotating mechanism is set on the mounting platform 2, and the output end of the rotating mechanism is connected to the fan-shaped turntable 3 to drive the fan-shaped turntable 3 to rotate vertically and circumferentially. The push rod 5 is horizontally set on the rear side of the fan-shaped turntable 3 and is set directly opposite the U-shaped placement groove 31. The moving mechanism is set on the mounting platform 2, and the output end of the moving mechanism is connected to the push rod 5 to drive the push rod 5 to move horizontally.

[0052] During blasting operations at the tunnel face, a traveling mechanism moves the lifting platform 1 to the face. The platform is then raised and lowered to fill detonators into blast holes at different heights. Before filling, detonators are placed in batches in the detonator placement cylinder 41, and stemming material is placed in batches in the stemming material placement cylinder 42. Due to the presence of the fan-shaped turntable 3, when the U-shaped placement groove 31 is positioned between the detonator placement cylinder 41 and the stemming material placement cylinder 42, the turntable 3 blocks the bottom of both cylinders, temporarily storing the detonators and stemming material. During filling, the U-shaped guide groove 32 is aligned with the blast hole, referring to... Figure 4 and Figure 5As shown, firstly, the rotating mechanism drives the sector-shaped turntable 3 to rotate counterclockwise, causing the U-shaped placement groove 31 to rotate directly below the detonator placement cylinder 41. At this time, the detonators in the detonator placement cylinder 41 will fall into the U-shaped placement groove 31. Then, the sector-shaped turntable 3 is rotated clockwise, so that the U-shaped placement groove 31 is located between the detonator placement cylinder 41 and the clay placement cylinder 42, and directly opposite the U-shaped guide groove 32. At this time, the moving mechanism drives the push rod 5 to move forward, using the push rod 5 to push the detonators in the U-shaped placement groove 31 into the U-shaped guide groove 32. Then, the push rod 5 pushes the detonators in the U-shaped guide groove 32 into the borehole. Then, the moving mechanism drives the push rod 5 to move backward, causing the push rod 5 to retract from the U-shaped guide groove 32 and the U-shaped placement groove 31. Then, the rotating mechanism drives the sector-shaped turntable 3 to rotate clockwise, causing the U-shaped placement groove 31 to rotate directly below the clay placement cylinder 42. At this time, the clay in the clay placement cylinder 42 will fall into the borehole. The detonator falls into the U-shaped placement groove 31, and then the fan-shaped turntable 3 is rotated counterclockwise so that the U-shaped placement groove 31 is located between the detonator placement cylinder 41 and the clay placement cylinder 42, and is directly opposite the U-shaped guide groove 32. At this time, the moving mechanism drives the push rod 5 to move forward, and the push rod 5 pushes the clay in the U-shaped placement groove 31 into the U-shaped guide groove 32. Then, the push rod 5 pushes the clay in the U-shaped guide groove 32 to the borehole opening to seal the detonator. Finally, the push rod 5 is moved backward from the U-shaped guide groove 32 and the U-shaped placement groove 31, thus completing the entire process of loading a detonator. The subsequent loading of other barrels is the same as the above process, and will not be described in detail here. With this device, the continuous batch picking and loading of detonators and clay can be completed. The construction personnel do not need to carry detonators and clay themselves. Compared with the traditional operation of filling the borehole one by one by hand with detonators and clay, the operation efficiency is improved.

[0053] As a specific implementation of the rotating mechanism, such as Figure 2 , Figure 3 Figure 5 and Figure 6As shown, the rotating mechanism includes a mounting block 6, a slider 63, two arc-shaped springs 64, two first limiting blocks 65, and a gripping rod 66. The mounting block 6 is semi-circular and vertically positioned on the rear side of the fan-shaped turntable 3. The bottom of the mounting block 6 is fixed to the bottom of the mounting platform 2 by a support rod 61. The top of the mounting block 6 is lower than the U-shaped placement groove 31. An arc-shaped mounting slot 62 is provided through the side wall of the mounting block 6, and the arc-shaped mounting slot 62 is concentrically positioned with the fan-shaped turntable 3. The slider 63 is slidably engaged in the arc-shaped mounting slot 62. The two arc-shaped springs 64... The mounting block 64 is symmetrically arranged on both sides of the slider 63 within the arc-shaped mounting slot 62. One end of each arc-shaped spring 64 is connected to the slider 63, and the other end of each arc-shaped spring 64 is connected to the inner wall of the arc-shaped mounting slot 62. Two first limiting blocks 65 are arranged on the front and rear sides of the mounting block 6, and the two first limiting blocks 65 are fixed to the front and rear side walls of the slider 63 respectively. The limiting block 65 located on the front side of the mounting block 6 is fixedly connected to the rear side wall of the fan-shaped turntable 3. The gripping rod 66 is horizontally fixed on the first limiting block 65 located on the rear side of the mounting block 6.

[0054] When the rotating mechanism drives the sector-shaped turntable 3 to rotate, the construction worker can use the grip rod 66 to move the slider 63 within the arc-shaped mounting slot 62. When the grip rod 66 is pulled or pushed counterclockwise, it will cause the slider 63 to rotate counterclockwise. During the movement of the slider 63, the first limit block 65 will drive the sector-shaped turntable 3 to rotate counterclockwise synchronously. Similarly, when the grip rod 66 is pulled or pushed clockwise, it will drive the sector-shaped turntable 3 to rotate clockwise synchronously. Since the two arc-shaped springs 64 are symmetrically arranged on both sides of the slider 63, whether the slider 63 rotates clockwise or counterclockwise, one arc-shaped spring 64 will be in a compressed state and the other arc-shaped spring 64 will be in an extended state. When the construction worker releases the grip rod 66, the elastic force of the two arc-shaped springs 64 will cause the slider 63 to automatically move to the center of the arc-shaped mounting slot 62, thereby driving the sector-shaped turntable 3 to rotate counterclockwise. The U-shaped placement groove 31 on the turntable 3 automatically moves to the middle position between the detonator placement cylinder 41 and the clay placement cylinder 42, and is directly opposite the U-shaped guide groove 32, thereby realizing the automatic positioning function. This facilitates positioning and filling, and also saves physical strength. Therefore, the above setting simplifies the process. The construction personnel only need to rotate the U-shaped placement groove 31 counterclockwise by holding the lever 66 to obtain the detonator directly below the detonator placement cylinder 41, and then release the lever 66 to automatically move the U-shaped placement groove 31 to move the detonator to the middle position between the detonator placement cylinder 41 and the clay placement cylinder 42 to fill the blast hole with the detonator. Then, by rotating the U-shaped placement groove 31 clockwise by holding the lever 66 to obtain the clay directly below the clay placement cylinder 42, and then releasing the lever 66, the U-shaped placement groove 31 will automatically move the detonator to the middle position between the detonator placement cylinder 41 and the clay placement cylinder 42 to seal the detonator at the blast hole opening with the clay.

[0055] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, in order to limit the rotation limit position of the fan-shaped turntable 3 and prevent excessive rotation angle, a stop bar 67 is fixed on the rear side wall of the mounting block 6. The stop bar 67 is located directly below the U-shaped placement groove 31, and the height of the stop bar 67 is higher than the top height of the mounting block 6. Two inclined second limiting blocks 68 are fixed on both sides of the top of the mounting block 6. The two second limiting blocks 68 are respectively positioned directly below the detonator placement cylinder 41 and the clay placement cylinder 42. With the above arrangement, when the fan-shaped turntable 3 rotates counterclockwise and causes the U-shaped placement groove 31 to rotate... Directly below the detonator placement cylinder 41, the stop lever 67 will rotate with the sector-shaped turntable 3 and contact the second limiting block 68 on the left side to limit the maximum counterclockwise rotation angle. This ensures that when the sector-shaped turntable 3 rotates to its maximum counterclockwise angle, the detonator in the detonator placement cylinder 41 will fall into the U-shaped placement groove 31. Similarly, the second limiting block 68 on the right side will limit the maximum clockwise rotation angle of the sector-shaped turntable 3, ensuring that when the sector-shaped turntable 3 rotates to its maximum clockwise angle, the clay in the clay placement cylinder 42 will fall into the U-shaped placement groove 31.

[0056] like Figure 4 As shown, in order to facilitate the sliding of the detonators stored in the detonator placement cylinder 41 into the U-shaped placement groove 31, and in order to facilitate the sliding of the gun clay stored in the gun clay placement cylinder 42 into the U-shaped placement groove 31, inclined platforms 43 are provided at the bottom outlets of both the detonator placement cylinder 41 and the gun clay placement cylinder 42, and the inclined surface of each inclined platform 43 faces the U-shaped guide groove 32.

[0057] As a possible specific implementation method for the mobile mechanism, such as Figure 2 , Figure 3 and Figure 7 As shown, the moving mechanism includes a horizontally arranged tube 7. The bottom of the tube 7 is fixed to the bottom of the mounting platform 2 by a fixing rod 71. The push rod 5 is slidably locked inside the tube 7. Guide slots 72 are provided on both sides of the tube 7 along its length. A sliding rod 73 is slidably locked in each guide slot 72. One end of each sliding rod 73 extends into the tube 7 and is fixed to the side wall of the push rod 5. The other end of each sliding rod 73 extends out of the tube 7. In this embodiment, when the construction worker is filling the detonator, he holds one of the sliding rods 73 and pushes the sliding rod 73 forward to drive the push rod 5 to move forward synchronously, thereby completing the operation of filling the detonator or drilling mud. By pushing the sliding rod 73 backward, the push rod 5 is driven to move backward synchronously, thereby causing the sliding rod 73 to exit from the U-shaped guide slot 32 and the U-shaped placement slot 31.

[0058] Considering the different movement distances of the detonator inserted into the borehole and the borehole sealing mud, a telescopic rod assembly is provided on the side wall of the push rod 5 facing the U-shaped placement groove 31. The telescopic rod assembly includes a T-shaped rod 81. A T-shaped mounting groove 51 is opened on the side wall of the push rod 5 facing the U-shaped placement groove 31. The T-shaped rod 81 is slidably fitted into the T-shaped mounting groove 51. An electromagnet 82 is fixed on the groove wall of the U-shaped placement groove 31 facing the larger end of the T-shaped rod 81. One of the sliding rods 73 is provided with a push switch 83 for controlling the on and off of the electromagnet 82. An iron block 84 is embedded and fixed on the side wall of the larger end of the T-shaped rod 81 facing the electromagnet 82. Multiple horizontally arranged return springs 85 are connected to the side wall of the larger end of the T-shaped rod 81 facing away from the electromagnet 82. The other ends of the multiple return springs 85 are connected to the inner wall of the T-shaped mounting groove 51. In this embodiment, it should be noted that... Figure 8 As shown, when the electromagnet 82 is de-energized, the small end of the T-shaped rod 81 extends to the outside of the push rod 5 under the elastic force of multiple return springs 85. When the electromagnet 82 is energized and attracts the iron block 84, the T-shaped rod 81 retracts inside the push rod 5. Therefore, when the slide rod 73 is pushed forward to move the clay using the push rod 5, the electromagnet 82 is energized, the iron block 84 is attracted and compresses the multiple return springs 85, causing the T-shaped rod 81 to retract inside the push rod 5. When the slide rod 73 moves forward... When the guide slot 72 reaches its limit position, the push rod 5 can just push the mud to the borehole opening for sealing. When pushing the detonator, the push rod 5 moves the same distance but does not push the detonator completely into the borehole. At this time, press the push switch 83 once to de-energize the electromagnet 82. Then, under the elastic force of multiple return springs 85, the T-shaped rod 81 extends out from the push rod 5. The T-shaped rod 81 is used to push the detonator into the borehole again, so that the detonator is in the borehole and the explosion effect is guaranteed.

[0059] The detonator loading method using the detonator loading device for blasting operations described above includes the following specific steps:

[0060] When the U-shaped placement trough is between the detonator placement cylinder and the gun clay placement cylinder, the fan-shaped turntable blocks the bottom of the detonator placement cylinder and the gun clay placement cylinder, thereby temporarily storing the detonator and gun clay.

[0061] When loading, align the U-shaped guide groove with the borehole. First, control the fan-shaped turntable to rotate counterclockwise, so that the U-shaped placement groove rotates to be directly below the detonator placement tube. At this time, the detonator in the detonator placement tube will fall into the U-shaped placement groove. Then, rotate the fan-shaped turntable clockwise so that the U-shaped placement groove is located between the detonator placement tube and the clay placement tube, and is directly opposite the U-shaped guide groove. At this time, use the push rod to push the detonator in the U-shaped placement groove into the U-shaped guide groove. Then, use the push rod to push the detonator in the U-shaped guide groove into the borehole. Finally, remove the push rod from the U-shaped guide groove and the U-shaped placement groove.

[0062] Next, control the fan-shaped turntable to rotate clockwise, so that the U-shaped placement groove rotates to be directly below the clay placement cylinder. At this time, the clay in the clay placement cylinder will fall into the U-shaped placement groove. Then, rotate the fan-shaped turntable counterclockwise so that the U-shaped placement groove is located between the detonator placement cylinder and the clay placement cylinder, and is directly opposite the U-shaped guide groove. At this time, use the push rod to push the clay in the U-shaped placement groove into the U-shaped guide groove. Then use the push rod to push the clay in the U-shaped guide groove to the borehole opening to seal the detonator. Finally, make the push rod move backward out of the U-shaped guide groove and the U-shaped placement groove, thus completing the entire process of loading a detonator. The same process is used to load the remaining barrels.

[0063] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

10. A detonator loading method using the detonator loading device for blasting construction as described in any one of claims 1-9, characterized in that, include: When the U-shaped placement trough is between the detonator placement cylinder and the gun clay placement cylinder, the fan-shaped turntable blocks the bottom of the detonator placement cylinder and the gun clay placement cylinder, thereby temporarily storing the detonator and gun clay. When loading, align the U-shaped guide groove with the borehole. First, control the fan-shaped turntable to rotate counterclockwise, so that the U-shaped placement groove rotates to be directly below the detonator placement tube. At this time, the detonator in the detonator placement tube will fall into the U-shaped placement groove. Then, rotate the fan-shaped turntable clockwise so that the U-shaped placement groove is located between the detonator placement tube and the clay placement tube, and is directly opposite the U-shaped guide groove. At this time, use the push rod to push the detonator in the U-shaped placement groove into the U-shaped guide groove. Then, use the push rod to push the detonator in the U-shaped guide groove into the borehole. Finally, remove the push rod from the U-shaped guide groove and the U-shaped placement groove. Next, control the fan-shaped turntable to rotate clockwise, so that the U-shaped placement groove rotates to be directly below the clay placement cylinder. At this time, the clay in the clay placement cylinder will fall into the U-shaped placement groove. Then, rotate the fan-shaped turntable counterclockwise so that the U-shaped placement groove is located between the detonator placement cylinder and the clay placement cylinder, and is directly opposite the U-shaped guide groove. At this time, use the push rod to push the clay in the U-shaped placement groove into the U-shaped guide groove. Then use the push rod to push the clay in the U-shaped guide groove to the borehole opening to seal the detonator. Finally, make the push rod move backward out of the U-shaped guide groove and the U-shaped placement groove, thus completing the entire process of loading a detonator. The same process is used to load the remaining barrels.
