Description

Technical Field

[0001] The present application relates to the field of blasting equipment, and in particular to a mine blasting charging device. Background Art

[0002] Blasting involves using the immense pressure generated by the explosion of explosives within a medium such as soil or rock to break it. To achieve optimal blasting results, the mass of explosives required is typically calculated based on the soil quality and the blasting area. Based on this calculated amount, several blastholes are drilled and installed. During blasting, workers directly insert explosive rolls into the holes, which gravity forces to the bottom of the holes. The designated charge is then placed according to the designed charge volume.

[0003] In related art, Chinese patent application number CN113932672A discloses a mining blasting charging device comprising a plurality of mounting members connected end to end. The mounting members comprise a mounting tube and a connecting tube fixed to the lower end face of the mounting tube and parallel to the mounting tube. The connecting tube is inserted into the corresponding mounting tube below. The upper end face of the mounting tube is provided with a connecting member for fixing the connecting tube and preventing the connecting tube from moving relative to the mounting tube. The connecting member comprises a connecting rod bonded to the upper end face of the mounting tube. The upper end of the connecting rod is bonded to a clamp that is sleeved on the outer surface of the upper connecting tube. By rotating the screw on the clamp, the clamp tightens the connecting tube, thereby connecting two adjacent mounting members. The mounting tube is provided with a support device for placing a charge roll. The support device comprises a support tube connected to the outer wall of the mounting tube, perpendicular to the mounting tube and integrally formed with the mounting tube. A positioning tube is inserted into the support tube. One end of the positioning tube is inserted into the support tube, and the other end of the positioning tube is fixed to an abutment plate parallel to the axis of the mounting tube.

[0004] During the blasting process, workers can connect several mounting parts end to end based on the depth of the blasthole, insert the connecting tube into the mounting tube, adjust the distance between adjacent mounting tubes, and use clamps to tighten the connecting tubes to connect the two adjacent mounting parts. Next, the drug roll is placed on the support tube and clamped together using the abutment plate and mounting tube to install the drug roll. The water bag is installed on the support plate and the mounting tube is filled with water. During the blasting process, the mounting tube, connecting tube, support tube, positioning tube, abutment plate, and water bag will be destroyed, which has a certain dust suppression effect.

[0005] The prior art has the following defects: first, an installation member is inserted into the blast hole, when the connecting cylinder does not reach the bottom of the blast hole, the connecting cylinder on the next connecting member is aligned with the installation cylinder already in the blast hole and is inserted into the installation cylinder, then the hoop is tightened by using a bolt to fix the connecting cylinder in the installation cylinder, and then the conveying into the blast hole is continued, when the initial connecting cylinder has not reached the bottom of the blast hole, the above steps are repeated, so that a plurality of installation members are connected in sequence until the depth of the blast hole is met, and in this process, the new installation member is taken and installed while conveying, which is inconvenient to operate, and needs to be improved. SUMMARY

[0006] In order to meet the depth of the blast hole, a new installation member needs to be taken and installed on the basis of the original installation member, which causes the problem of inconvenient operation, and the application provides a mine blasting charging device.

[0007] The mine blasting charging device provided by the application adopts the following technical scheme:

[0008] A mine blasting charging device comprises:

[0009] A plurality of installation sleeves, a water bag is arranged on the side wall of the installation sleeve. One end of the installation sleeve is an open structure, and a plurality of installation sleeves can be arranged in a spiral shape;

[0010] A plurality of connecting rods, the connecting rod is located between adjacent installation sleeves, one end of the connecting rod is fixed with the end of one of the installation sleeves, and the other end is inserted into another installation sleeve;

[0011] A plurality of sliding blocks, the sliding block corresponds to the installation sleeve one by one and is arranged in the installation sleeve and can move in the installation sleeve, and one end of the connecting rod inserted into the installation sleeve is hinged on the sliding block;

[0012] A plurality of installation assemblies, the installation assembly corresponds to the installation sleeve one by one and is arranged on the installation cylinder for fixing the charge.

[0013] By adopting the above technical scheme, in the initial state, the sliding block moves to the open structure of the installation sleeve and drives the connecting rod to move out of the installation sleeve completely, at this time, the hinge point of the sliding block and the connecting rod also moves out of the installation sleeve, the connecting rod rotates around the hinge point of the connecting rod and the sliding block, until the connecting rod and the sliding block are perpendicular, so that the two adjacent installation sleeves are arranged vertically, then the next connecting rod is repeated above steps and rotated in the same direction, so that the two installation sleeves separated by a single installation sleeve are arranged relatively parallel, so that the plurality of installation sleeves are arranged in a spiral shape, and are convenient to store.

[0014] When blasting is required, the connecting rod at the outermost end of the stored several mounting sleeves is inserted into the blasthole, and then the next connecting rod is turned over so that the next mounting sleeve is coaxial with the previous mounting sleeve. Then the sliding block is moved in the mounting sleeve to drive the connecting rod to be inserted into the mounting sleeve. The inner wall of the mounting sleeve abuts against the connecting rod, which restricts the connecting rod and prevents it from rotating. That is, the two adjacent mounting sleeves maintain a coaxial state and extend into the blasthole. Repeat the above steps to achieve coaxial splicing of several mounting sleeves and insert them into the blasthole until the length of the spliced ​​mounting sleeves meets the depth of the blasthole.

[0015] When the explosive cartridge explodes in the blasthole, the mounting sleeve, connecting rod, and water bag are all destroyed, thus suppressing dust during the blasting process. During the insertion of the mounting sleeve into the blasthole, the connecting rod can be flipped to achieve the coaxial splicing of two adjacent mounting sleeves, which is convenient to operate.

[0016] Optionally, a fixing assembly for fixing the sliding block in the mounting sleeve is further included, and the fixing assembly includes:

[0017] A fixing rod, a fixing hole is formed on the inner wall of the mounting sleeve, the fixing hole is located at an end of the mounting sleeve away from the mounting sleeve opening structure, the fixing rod is inserted into the fixing hole and can move in the fixing hole, and a positioning hole for inserting the fixing rod is formed on the side wall of the sliding block;

[0018] A fixing spring, the fixing spring being disposed in the fixing hole and being used to push the fixing rod toward the center axis of the mounting sleeve;

[0019] A pull rod, one end of which is fixed to the fixing rod, and the other end of which extends out of the mounting sleeve.

[0020] By adopting the above technical solution, after the connecting rod rotates to make the adjacent mounting sleeves coaxial, the sliding block is moved within the mounting sleeve, driving the connecting rod to be inserted into the mounting sleeve. The pull rod is pulled, causing the fixing rod to compress the fixing spring and retract it into the fixing hole, thus preventing interference with the movement of the sliding block. When the sliding block moves to abut the inner wall of the mounting sleeve on the side away from the opening structure, and the positioning hole is aligned with the fixing rod, the force pulling the pull rod is removed, and the fixing rod is inserted into the positioning hole under the action of the fixing spring, thereby securing the sliding block within the mounting sleeve. This prevents the connecting rod from completely moving out of the mounting sleeve and rotating, thereby increasing the stability of maintaining the coaxiality of the adjacent mounting sleeves.

[0021] Optionally, also include:

[0022] A sliding rod, which passes through the sliding block and is arranged along the width direction of the mounting tube, and has sliding holes at both ends of the sliding rod;

[0023] Two moving rods are arranged at two ends of the sliding rod respectively, the moving rods are inserted into the sliding hole and can move in the sliding hole, a moving groove is arranged on the side wall of the mounting cylinder along the length direction of the mounting cylinder, the moving rods pass through the moving groove and can move in the moving groove;

[0024] Two pushing springs are arranged in the sliding hole and correspond to the moving rods respectively, and are used for pushing the moving rods away from the sliding rod.

[0025] By using the above technical scheme, when the sliding block moves, the moving rods move in the moving groove, the inner wall of the moving groove and the side wall of the moving rod abut, which limits and guides the moving rod, so that the moving rod does not deviate during the movement, and the stability of the movement of the sliding block is increased. At the same time, when one end of the sliding block extends out of the mounting sleeve, the moving rod also moves to one end of the moving groove, which limits the continuous movement of the moving rod, so that the sliding block cannot move out of the mounting sleeve completely. When a plurality of mounting sleeves are spliced into a coaxial length that meets the depth of the blast hole and are inserted into the blast hole, the moving rods are pressed, so that the moving rods press the pushing springs and are completely accommodated in the sliding hole. At this time, the moving groove cannot limit the movement, so that the sliding block can be completely separated from the mounting sleeve, so that the adjacent mounting sleeves are separated, the mounting sleeve extending into the blast hole is detached from the mounting sleeves that are arranged together, and the blasting is facilitated, and the unused cartridges are not damaged.

[0026] Optionally, a limiting assembly is arranged on the mounting sleeve, and the limiting assembly comprises:

[0027] A limiting rod is arranged along the width direction of the mounting cylinder and is rotationally connected to the mounting cylinder, and opposite screw structures are arranged at two ends of the limiting rod;

[0028] A guide rod is fixed to the mounting sleeve and is parallel to the limiting rod;

[0029] Two limiting plates are arranged at two ends of the guide rod respectively and are threadedly connected to the limiting rod, the moving rod is located between the two limiting plates, the guide rod passes through the limiting plates, and the limiting plates can move on the guide rod.

[0030] By using the above technical scheme, the limiting rod is rotated, the limiting plates are threadedly connected to the limiting rod, and the guide rod limits the rotation of the limiting plates around the limiting rod, so that the two limiting plates move towards each other at the same time until the limiting plates abut against the moving rod, the two limiting plates apply pressing force to the moving rod, and the moving rod is clamped and fixed, so that the sliding block can be fixed in the mounting sleeve. The sliding block can be fixed when moving to any position in the mounting sleeve, so that the distance between the adjacent mounting sleeves can be adjusted, that is, the distance between the adjacent cartridges is adjusted according to different mining conditions, so that the blasting effect is better.

[0031] Optionally, a magnet is fixed on the end wall of the mounting cylinder opening structure, and an iron sheet that is attracted to the magnet is arranged on the side wall of the connecting rod.

[0032] By adopting the above technical scheme, when the plurality of mounting sleeves are accommodated in a vortex shape, the connecting rod on the adjacent mounting sleeve is perpendicular to the mounting sleeve, at this time, the magnet and the iron sheet are attached to each other, so that the connecting rod is fixed in a state of being perpendicular to the sliding block, that is, the connecting rod is not easy to rotate, thereby increasing the stability of the plurality of mounting sleeves accommodated in a vortex shape.

[0033] Optionally, the installation assembly further comprises:

[0034] A rubber pad is fixed on one side of the limiting plate close to the moving rod;

[0035] An abutting spring is arranged in the rubber pad and pushes the side of the rubber pad close to the moving rod in the direction close to the moving rod.

[0036] By adopting the above technical scheme, when the two limiting plates drive the rubber pad to abut against the moving rod, the rubber pad plays a protective role, so that the limiting plate and the moving rod are not easy to wear. While the limiting plate clamps and fixes the moving rod, the abutting spring pushes the rubber pad to press the moving rod, thereby increasing the pressing force received by the two opposite sides of the moving rod, that is, the fastening of the limiting plate clamping and fixing the moving rod is increased.

[0037] Optionally, the installation assembly comprises:

[0038] A positioning sleeve is fixed at one end on the mounting sleeve, and the other end is an open structure, a plurality of accommodating holes are uniformly arranged on the inner wall of the positioning sleeve along the length direction of the positioning sleeve;

[0039] A positioning rod is inserted into the positioning sleeve and can move in the positioning sleeve along the length direction of the positioning sleeve, one end of the positioning rod close to the mounting sleeve is fixed with a limiting block, and the other end is fixed with an abutting plate, and the abutting plate is parallel to the mounting sleeve;

[0040] A limiting block is inserted into and movable in the accommodating hole, and the limiting block can be adaptively inserted into the adjacent positioning block;

[0041] A positioning spring is arranged in the accommodating hole and used to push the limiting block in the direction close to the axis of the positioning sleeve;

[0042] A connecting rope is fixed at one end with the limiting block and extends out of the positioning sleeve at the other end.

[0043] By adopting the above technical scheme, when the cigarette is placed between the abutment plate and the outer side wall of the mounting sleeve, then the abutment plate is moved towards the mounting sleeve, so that the positioning rod drives the limiting block to move in the positioning sleeve, the connecting rope is pulled, so that the limiting block is pressed into the containing hole to avoid interfering with the movement of the limiting block. When the abutment plate abuts against the cigarette, the end of the limiting block extends out of the containing hole under the action of the positioning spring, thereby limiting the limiting block between adjacent limiting blocks, so that the abutment plate cannot move away from the mounting sleeve, thereby clamping the cigarette to achieve the installation of the cigarette on the mounting sleeve. Since the distance between the abutment plate and the mounting sleeve can be adjusted, the abutment plate can clamp and fix the cigarette with different sizes, and the applicability is good.

[0044] Optionally, the side of the limiting block away from the mounting sleeve is provided with a guide surface, and the side of the guide surface close to the axis of the positioning sleeve is inclinedly arranged towards the mounting sleeve.

[0045] By adopting the above technical scheme, when the positioning rod drives the limiting block to move in the positioning sleeve towards the mounting sleeve, the limiting block abuts against and slides on the guide surface, and the guide surface plays a guiding role, so that the limiting block is pressed into the containing hole to avoid interfering with the movement of the limiting block, and the connecting rope does not need to be pulled, so that the positioning rod moves in the positioning sleeve towards the mounting sleeve more conveniently.

[0046] Optionally, the outer side of the positioning sleeve is provided with a positioning plate, and one end of the connecting rope extending out of the positioning sleeve is fixed with the positioning plate.

[0047] By adopting the above technical scheme, when the limiting block moves in the positioning sleeve away from the mounting sleeve, the positioning plate can drive all the connecting ropes to move away from the positioning sleeve at the same time, so that all the limiting blocks can be stored in the containing hole, without pulling each connecting rope corresponding to each limiting block one by one, and the operation is convenient.

[0048] Optionally, the device further comprises:

[0049] A rotating rod is vertically inserted into the positioning sleeve and can rotate in the positioning sleeve, and the rotating rod is threadedly connected with the positioning rod.

[0051] A transmission bevel gear is engaged with the rotating bevel gear, the transmission bevel gear is coaxially fixed with a driving rod, and one end of the driving rod away from the rotating rod extends out of the positioning sleeve.

[0052] By adopting the technical scheme, when the cartridge is placed between the abutting plate and the mounting sleeve, the driving rod is rotated to drive the transmission bevel gear to rotate the rotating bevel gear to rotate the rotating rod, the rotating rod is threadedly connected with the positioning rod, thereby driving the positioning rod to move in the positioning sleeve until the abutting plate abuts against the cartridge, the driving rod is stopped, the thread has a self-locking function, the abutting plate will not move and clamp the cartridge on the mounting sleeve, when the abutting plate clamps the cartridge and the limiting block is not located between the adjacent positioning blocks, the rotating rod and the positioning rod can also fix the abutting plate, and the accuracy of adjusting the distance between the abutting plate and the mounting sleeve is increased.

[0054] 1. When blasting is needed, the connecting rod at the outermost end of the stored mounting sleeve is inserted into the blast hole, the next connecting rod is turned over, the next mounting sleeve is coaxial with the previous mounting sleeve, then the sliding block is moved in the mounting sleeve to drive the connecting rod to be inserted into the mounting sleeve, the inner wall of the mounting sleeve abuts against the connecting rod to limit the rotation of the connecting rod, that is, the adjacent two mounting sleeves maintain a coaxial state and extend into the blast hole.

[0055] 2. When the length of the spliced mounting sleeves meets the depth of the blast hole and is inserted into the blast hole, the moving rod is pressed to extrude the push spring and completely store it in the sliding hole, at this time the moving groove cannot limit the sliding block, so that the sliding block can be completely separated from the mounting sleeve, thereby separating the adjacent mounting sleeves, realizing the disassembly of the mounting sleeves from the stored mounting sleeves, facilitating blasting, and avoiding damage to unused cartridges.

DETAILED DESCRIPTION

[0063] The following is combined with Figures 1-6 This application is described in further detail.

[0064] The embodiment of the present application discloses a mine blasting charging device. Figure 1 and Figure 2 The mining blasting charging device includes several horizontally placed mounting sleeves 10, on the side walls of which are fixed water bags 160 and mounting components 40. The mounting components 40 are used to fix the drug roll on the mounting sleeves 10. One end of the mounting sleeve 10 is an open structure and the other end is coaxially fixed with a connecting rod 20. Several mounting sleeves 10 are connected end to end, that is, the connecting rod 20 on the previous mounting sleeve 10 can be inserted into the next mounting sleeve 10.

[0065] When blasting is required, first fix an appropriate amount of explosive roll on the mounting sleeve 10 using the mounting assembly 40, then send the mounting sleeve 10 into the blast hole, and then align the connecting rod 20 on the new mounting sleeve 10 with the mounting sleeve 10 located in the blast hole and insert it into the mounting sleeve 10, so that several mounting sleeves 10 are spliced ​​to meet the depth of the blast hole. When the explosive roll blasts in the blast hole, the mounting sleeve 10, the connecting rod 20 and the water bag 160 are blown up, thereby playing a role in dust suppression during the blasting process.

[0066] Reference Figure 2 and Figure 3The mounting assembly 40 comprises a positioning sleeve 41, a positioning rod 42, positioning blocks 43, positioning springs 44 and connecting ropes 45. The positioning sleeve 41 is vertically arranged, one end of the positioning sleeve 41 is fixed on the mounting sleeve 10, and the other end is of an open structure. A plurality of accommodating holes 411 are uniformly arranged on the inner wall of the positioning sleeve 41 along the length direction of the positioning sleeve 41. The positioning blocks 43 and the positioning springs 44 are both inserted into the accommodating holes 411. One end of the positioning spring 44 is fixed to the inner wall of the accommodating hole 411 away from the central axis of the positioning sleeve 41, and the other end is fixed to the end of the positioning block 43 away from the central axis of the positioning sleeve 41.

[0067] With reference to Figure 3 A guide surface 431 is cut on the top wall of the end of the positioning block 43 inserted into the positioning sleeve 41. The guide surface 431 is arranged obliquely towards the mounting sleeve 10 near the end close to the central axis of the positioning sleeve 41. Each positioning block 43 is fixed with a connecting rope 45. The end of the connecting rope 45 away from the positioning block 43 extends out of the positioning sleeve 41. The outer side of the positioning sleeve 41 is provided with a positioning plate 110. The end of the connecting rope 45 extending out of the positioning sleeve 41 is fixed to the positioning plate 110.

[0068] With reference to Figure 3 The positioning rod 42 is adapted to be inserted into the positioning sleeve 41. The positioning rod 42 is movable up and down in the positioning sleeve 41. The positioning rod 42 is integrally formed with a limiting block 421 on the side wall of the positioning sleeve 41. The limiting block 421 is located at the end of the positioning rod 42 close to the mounting sleeve 10. The other end is integrally formed with an abutting plate 422. The limiting block 421 is insertable between adjacent positioning blocks 43.

[0069] The cigarette is placed between the abutting plate 422 and the mounting sleeve 10. Then the abutting plate 422 is moved towards the mounting sleeve 10. The positioning rod 42 drives the limiting block 421 to move in the positioning sleeve 41. The limiting block 421 abuts against and slides on the guide surface 431. The guide surface 431 plays a guiding role. The positioning block 43 is pressed to be accommodated into the accommodating hole 411, without interfering with the movement of the limiting block 421. When the abutting plate 422 abuts against the cigarette, the end of the positioning block 43 extends out of the accommodating hole 411 under the action of the positioning spring 44. Thus, the limiting block 421 is limited between adjacent positioning blocks 43. The abutting plate 422 cannot move away from the mounting sleeve 10. Thus, the cigarette is clamped and fixed on the mounting sleeve 10. The distance from the abutting plate 422 to the mounting sleeve 10 is adjustable. Thus, the abutting plate 422 can clamp and fix cigarettes of different sizes, with good applicability.

[0070] When the adjusting of the medicine roll is needed, the positioning plate 110 is directly pulled, all the connecting ropes 45 are simultaneously moved away from the positioning sleeve 41, all the positioning blocks 43 are completely accommodated into the accommodating holes 411, the positioning rod 42 drives the abutting plate 422 to move away from the mounting sleeve 10.

[0071] With reference to Figure 3 , in order to increase the accuracy of adjusting the distance between the abutting plate 422 and the mounting sleeve 10, a rotating rod 120 is vertically arranged in the positioning sleeve 41, the rotating rod 120 is rotationally connected in the positioning sleeve 41, a rotating bevel gear 130 is coaxially fixed on the rotating rod 120, the rotating bevel gear 130 is engaged with a transmission bevel gear 140, the rotating bevel gear 130 is perpendicular to the transmission bevel gear 140, a driving rod 150 is coaxially fixed on the transmission bevel gear 140, and the driving rod 150 penetrates out of the positioning sleeve 41.

[0072] When the medicine roll is placed between the abutting plate 422 and the mounting sleeve 10, the driving rod 150 is rotated, the transmission bevel gear 140 is rotated to drive the rotating bevel gear 130 to rotate, the rotating rod 120 is rotated, the rotating rod 120 is threadedly connected with the positioning rod 42, thereby driving the positioning rod 42 to move in the positioning sleeve 41 until the abutting plate 422 abuts against the medicine roll, the driving rod 150 is stopped, the thread has a self-locking function, the abutting plate 422 will not move and the medicine roll will not be clamped on the mounting sleeve 10, when the abutting plate 422 clamps the medicine roll, the limiting block 421 is not located between the adjacent positioning blocks 43, the rotating rod 120 and the positioning rod 42 cooperate to fix the abutting plate 422.

[0073] With reference to Figure 4 and Figure 5 , the mounting sleeve 10 is provided with a sliding block 30, the sliding block 30 is movable in the mounting sleeve 10, and one end of the connecting rod 20 inserted into the mounting sleeve 10 is hinged on the sliding block 30. A sliding rod 60 is horizontally arranged in the sliding block 30, the sliding rod 60 is arranged along the width direction of the mounting sleeve 10, sliding holes 61 are formed at both ends of the sliding rod 60, a moving rod 70 is horizontally inserted into the sliding holes 61, the moving rod 70 is movable in the sliding holes 61, a propelling spring 80 is arranged in the sliding hole 61, one end of the propelling spring 80 is fixed to the inner wall of the sliding hole 61 close to the center of the sliding rod 60, and the other end is fixed to the end of the moving rod 70 close to the center of the sliding rod 60. A moving groove 12 is formed on the side wall of the mounting sleeve 10 along the length direction of the mounting sleeve 10, the moving rod 70 is fittedly arranged in the moving groove 12 and is movable in the moving groove 12. When the moving rod 70 moves to the end of the moving groove 12 close to the opening structure of the mounting sleeve 10, the sliding block 30 drives the connecting rod 20 to completely move out of the mounting sleeve 10.

[0074] With reference to Figure 1 and Figure 4, initial state, the sliding block 30 is moved to the limit position near the opening structure of the mounting sleeve 10, that is, the moving rod 70 is moved to one end of the moving groove 12 near the opening structure of the mounting sleeve 10, at this time the connecting rod 20 is completely moved out of the mounting sleeve 10, the connecting rod 20 is rotated to be perpendicular to the mounting sleeve 10, then the next connecting rod 20 is repeated above the same direction rotation, so that the two mounting sleeves 10 spaced apart by a single mounting sleeve 10 are arranged in parallel, so that the mounting sleeves 10 are arranged in a vortex shape, facilitating storage.

[0075] When blasting is needed, the connecting rod 20 at the outermost end of the stored mounting sleeve 10 is inserted into the blast hole, and the next connecting rod 20 is turned over so that the next mounting sleeve 10 is coaxial with the previous mounting sleeve 10, then the sliding block 30 is moved in the mounting sleeve 10, driving the connecting rod 20 to be inserted into the mounting sleeve 10, the inner wall of the mounting sleeve 10 abuts against the connecting rod 20, limiting the rotation of the connecting rod 20, that is, the adjacent two mounting sleeves 10 maintain the coaxial state and extend into the blast hole. Repeat the above steps to achieve the coaxial splicing of the mounting sleeves 10 and the insertion into the blast hole until the length of the spliced mounting sleeves 10 meets the depth of the blast hole.

[0076] When the length of the spliced mounting sleeves 10 meets the depth of the blast hole and is inserted into the blast hole, the moving rod 70 is pressed so that the moving rod 70 extrudes the push spring 80 and is completely stored in the sliding hole 61, at this time the moving groove 12 cannot limit the movement of the sliding block 30, so that the sliding block 30 can be completely separated from the mounting sleeve 10, thereby separating the adjacent mounting sleeves 10, achieving the disassembly of the mounting sleeves 10 from the stored mounting sleeves 10, facilitating blasting without damaging unused cartridges.

[0077] Referring to Figure 4 and Figure 5 When the mounting sleeves 10 are stored in a vortex shape, the connecting rod 20 on the adjacent mounting sleeve 10 is perpendicular to the mounting sleeve 10, in order to fix the connecting rod 20 on the mounting sleeve 10 in a state perpendicular to the sliding block 30, that is, the connecting rod 20 is not easy to rotate, thereby increasing the stability of the vortex structure of the stored mounting sleeves 10. A magnet 13 is embedded on the end of the opening structure of the mounting sleeve 10, and an iron sheet 21 is embedded on the side wall of the connecting rod 20, when the connecting rod 20 extends out of the mounting sleeve 10 and is perpendicular to the mounting sleeve 10, the magnet 13 and the iron sheet 21 are attracted to each other.

[0078] Referring to Figure 3When the moving rod 70 moves to the end of the moving slot 12 away from the opening structure of the mounting sleeve 10, i.e. the connecting rod 20 is received to the limit position in the mounting sleeve 10, in order to fix the sliding block 30 on the mounting sleeve 10, a fixing hole 11 is formed on the inner wall of the mounting sleeve 10, a fixing rod 51 is inserted in the fixing hole 11, the positioning rod 42 is fixed with a pull rod 170, and the end of the pull rod 170 away from the fixing rod 51 extends out of the mounting sleeve 10. A fixing spring 52 is arranged in the fixing hole 11, one end of the fixing spring 52 is fixed to the inner wall of the fixing hole 11, and the other end is fixed to the fixing rod 51. A positioning hole 31 is formed on the side wall of the sliding block 30 for inserting the fixing rod 51.

[0079] With reference to Figure 2 and Figure 6 , in order to realize the fixation of the sliding block 30 in any position in the mounting sleeve 10, the distance between adjacent mounting sleeves 10 can be adjusted, i.e. the distance between adjacent cartridges can be adjusted according to different mining conditions, so that the blasting effect is better. A limiting assembly 90 is arranged on the side wall of the mounting sleeve 10, the limiting assembly 90 includes a limiting rod 91, a guide rod 92 and two limiting plates 93, the limiting rod 91 and the guide rod 92 are vertically arranged, and the limiting rod 91 and the guide rod 92 are located on both sides of the length direction of the moving slot 12, the limiting rod 91 is rotationally connected to the mounting sleeve 10, the limiting rod 91 is a bidirectional screw rod, i.e. the two ends of the limiting rod 91 are provided with thread structures with opposite rotation directions, one end of the limiting rod 91 is threadedly connected with one of the limiting plates 93, and the other end is threadedly connected with the other limiting plate 93, the guide rod 92 penetrates the limiting plate 93, the limiting plate 93 can move on the guide rod 92, and the moving rod 70 is located between the two limiting plates 93.

[0080] With reference to Figure 6 , in order to increase the fastening of the two limiting plates 93 clamping the moving rod 70, a rubber pad 931 is fixed on the side of the limiting plate 93 close to the moving rod 70, when the two limiting plates 93 drive the rubber pad 931 to abut against the moving rod 70, the rubber pad 931 plays a protection role, so that the limiting plate 93 and the moving rod 70 are not easy to wear. An abutting spring 9311 is vertically arranged in the rubber pad 931, the abutting spring 9311 pushes the rubber pad 931 to press the moving rod 70, so as to increase the pressing force received by the opposite sides of the moving rod 70.

[0081] The implementation principle of the mine blasting charging device is as follows: in the initial state, the sliding block 30 is moved to the opening structure of the mounting sleeve 10, and the connecting rod 20 is completely moved out of the mounting sleeve 10, at this time, the hinged point of the sliding block 30 and the connecting rod 20 is also moved out of the mounting sleeve 10, the connecting rod 20 is rotated with the hinged point of the connecting rod 20 and the sliding block 30 as the shaft until the connecting rod 20 and the sliding block 30 are perpendicular, so that the adjacent two mounting sleeves 10 are vertically arranged, then the next connecting rod 20 is rotated in the same direction according to the above steps, so that the two mounting sleeves 10 spaced by a single mounting sleeve 10 are relatively parallel, and the plurality of mounting sleeves 10 are arranged in a spiral shape, which is convenient for storage.

[0082] When blasting is needed, the connecting rod 20 at the outermost end of the plurality of mounting sleeves 10 is inserted into the blast hole, the next connecting rod 20 is turned over, so that the next mounting sleeve 10 is coaxial with the previous mounting sleeve 10, then the sliding block 30 is moved in the mounting sleeve 10, the connecting rod 20 is inserted into the mounting sleeve 10, the inner wall of the mounting sleeve 10 abuts against the connecting rod 20, which limits the connecting rod 20 from rotating, that is, the adjacent two mounting sleeves 10 maintain the coaxial state and extend into the blast hole. Repeat the above steps to realize the coaxial splicing of the plurality of mounting sleeves 10 and insert them into the blast hole until the length of the spliced plurality of mounting sleeves 10 meets the depth of the blast hole.

[0083] When the cartridge is blasted in the blast hole, the mounting sleeve 10, the connecting rod 20 and the water bag 160 are all destroyed, thereby playing a dust suppression role in the blasting process. In the process of inserting the mounting sleeve 10 into the blast hole, the connecting rod 20 is turned over, so that the adjacent two mounting sleeves 10 are coaxially spliced, which is convenient to operate.

[0084] The above are preferred embodiments of the present application, but do not limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
