Description

Technical Field

[0001] The invention relates to the technical field of mine blasting, in particular to a blasting detonating device used in mine development. Background Art

[0002] Mine blasting is a key link in mining operations. Its purpose is to crush ore and rock to facilitate subsequent loading, transportation and processing.

[0003] In the existing mine blasting, construction workers first use drilling equipment to drill holes in the mine where blasting is required, then carry the blasting detonator to the drilling location, and then hold the blasting detonator and insert it into the drill hole in the mine, and finally detonate the blasting detonator through an induction device to carry out blasting.

[0004] Moreover, existing mine blasting workers are unable to determine the depth of each borehole, so the amount of explosives required for boreholes of different depths is also different. If boreholes of different depths do not have a matching amount of explosives, the ideal blasting effect cannot be achieved. At the same time, when there are too many blasting detonators and the boreholes are relatively shallow, the strong shock waves and flying rocks generated by the explosion will pose a safety hazard to the surrounding personnel. At the same time, when there are too few blasting detonators and the boreholes are relatively deep, the mine blasting standards cannot be met and mining cannot be carried out. At the same time, construction workers hold explosives and place them into the boreholes, which greatly increases the exposure time in the dangerous area and increases the safety risks of the workers. At the same time, construction workers also need to constantly pick up explosives and place them, which prolongs the duration of the entire mine blasting.

[0005] Therefore, a blasting detonation device for mining is proposed. Summary of the invention

[0006] The object of the present invention is to provide a blasting and detonating device for use in mining to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a blasting detonation device for mining, comprising a rectangular shell, two groups of rollers are arranged at the bottom of the rectangular shell, each group of rollers is arranged with no less than two rollers, and no less than four rollers are arranged, a handle is arranged on the side wall of the rectangular shell, an automatic ammunition filling component is arranged inside the rectangular shell, the automatic ammunition filling component comprises a sliding cavity one opened inside the rectangular shell, a loading shell is slidably connected inside the sliding cavity one, a groove one is opened inside the loading shell, a spring one is fixedly connected to the bottom of the groove one, a rubber plate one is fixedly connected to the end of the spring one away from the bottom of the groove one, a plurality of blasting detonators are placed inside the groove one, and a detonation sensor is fixedly connected to the side wall of the rectangular shell.

[0008] Furthermore, a press-and-ejection assembly is provided inside the rectangular shell, and the press-and-ejection assembly includes a sliding cavity 2 opened inside the rectangular shell, and a spring 2 is symmetrically fixedly connected to the upper surface of the rectangular shell, and no less than two springs 2 are provided, and the tops of the two springs 2 are fixedly connected to a pressing plate, and the bottom of the pressing plate is fixedly connected to a sliding column.

[0009] Furthermore, a depth measuring component is provided on the upper surface of the pressing plate, and the depth measuring component includes fixed blocks symmetrically fixedly connected to the upper surface of the pressing plate, and at least two fixed blocks are provided, a soft tape measure is rotatably connected between the two fixed blocks, and rotating disks are fixedly connected to both side walls of the soft tape measure, respectively, and a torsion spring is fixedly connected between the two rotating disks and the fixed blocks, an electric suction cup is fixedly connected to the bottom end of the soft tape measure, and a circular hole is opened inside the sliding column.

[0010] Furthermore, a limit assembly is arranged inside the rectangular shell, and the limit assembly includes a second groove opened inside the rectangular shell, the inner cavity of the second groove is fixedly connected to an electric telescopic rod, the output shaft end of the electric telescopic rod is fixedly connected to a second rubber plate, and the bottom of the rectangular shell is fixedly connected to a guide tube, and a guide hole is opened inside the guide tube.

[0011] Furthermore, the loading shell is threadedly connected to the side wall of the rectangular shell, and the shell of the blasting detonator is made of iron.

[0012] Furthermore, the side of the rubber sheet 1 away from the spring 1 is in contact with the outer side of the blasting detonator, and the rubber sheet 1 is slidably adapted to the inner cavity of the groove 1.

[0013] Furthermore, the sliding column is slidably adapted to the interior of the sliding cavity 2, and the outer side of the sliding column is in conflict with the blasting detonator close to one side of the sliding column.

[0014] Furthermore, the fixed block is rotatably connected to the side wall of the rotating disc, and the width of the soft measuring tape is matched with the diameter of the circular hole.

[0015] Furthermore, the second rubber plate is slidably adapted in the second groove, and the upper surface of the second rubber plate is in contact with the bottom of the blasting detonator.

[0016] Furthermore, the size of the guide hole matches the size of the blasting detonator, and the size of the guide hole matches the size of the sliding column.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The depth measuring component setting can measure the depth of the drill hole, thereby effectively ensuring the number of blasting detonators placed by the staff. Drill holes of different depths require corresponding amounts of explosives to achieve the ideal blasting effect and avoid the situation where there are too many blasting detonators and the drill hole is relatively shallow, and the strong shock wave and flying rocks generated by the explosion may cause damage to the safety of surrounding personnel.

The electric suction cup and the torsion spring can buffer the vertical downward movement of the blasting detonator, further reducing the vertical downward impact force of the blasting detonator.

[0019] The setting of the press-discharge component enables the staff to evenly place the blasting detonators into the mine boreholes by pressing the pressing plate, thereby achieving uninterrupted filling of ammunition and effectively reducing the interval time between the placement of two blasting detonators each time.

[0020] The setting of the automatic filling ammunition assembly enables the workers to load blasting detonators directly at the blasting site without having to do so, greatly reducing the exposure time in dangerous areas. At the same time, it avoids the workers' need to constantly pick up blasting detonators for delivery, thereby reducing the workers' workload.

[0021] The setting of the rollers and the handles can prevent workers from directly contacting the blasting detonators, and at the same time facilitate the transportation of the blasting detonators to the drilling area of ​​the mine. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] A press-and-discharge assembly is provided inside the rectangular shell 1, and the press-and-discharge assembly includes a sliding cavity 10 opened inside the rectangular shell 1, and the sliding cavity 14 is connected to the sliding cavity 10.

[0027] A depth measuring assembly is provided on the upper surface of the pressing plate 12, and the depth measuring assembly includes a fixed block 14 symmetrically fixedly connected to the upper surface of the pressing plate 12, and at least two fixed blocks 14 are provided, and a soft tape measure 17 is rotatably connected between the two fixed blocks 14, and the two side walls of the soft tape measure 17 are respectively fixedly connected with rotating disks 15, and the fixed block 14 is rotatably connected to the side walls of the rotating disk 15, and a torsion spring 16 is fixedly connected between the two rotating disks 15 and the fixed block 14, and the bottom end of the soft tape measure 17 is fixedly connected to an electric suction cup 19, and a circular hole 18 is opened inside the sliding column 13, the width of the soft tape measure 17 is adapted to the diameter of the circular hole 18, and the soft tape measure 17 is partially placed in the circular hole 18.

[0028] A limiting component is arranged inside the rectangular shell 1, and the limiting component includes a groove 20 opened inside the rectangular shell 1, and the groove 20 is communicated with the sliding cavity 10, the inner cavity of the groove 20 is fixedly connected with an electric telescopic rod 21, and the output shaft end of the electric telescopic rod 21 is fixedly connected with a rubber plate 22, the rubber plate 22 is slidably adapted inside the groove 20, and the rubber plate 22 is slidably adapted with the sliding cavity 10, the upper surface of the rubber plate 22 is in contact with the bottom of the blasting detonator 9, the bottom of the rectangular shell 1 is fixedly connected with a guide tube 23, and one end of the guide tube 23 extends to the outside of the rectangular shell 1, a guide hole 24 is opened inside the guide tube 23, the size of the guide hole 24 is adapted to the size of the blasting detonator 9, the size of the guide hole 24 is adapted to the size of the sliding column 13, and the guide hole 24 is communicated with the sliding cavity 10.

[0029] The above implementation works as follows: The initialization steps are as follows: The staff unscrews the screws on the loading shell 5, and puts the blasting detonators 9 one by one into the groove 6. The staff aligns the loading shell 5 with the inside of the sliding cavity 4 and pushes it. The staff also threadably connects the screws on the loading shell 5 with the rectangular shell 1. The spring 17 is in a compressed state, the torsion spring 16 is not contracted, the electric suction cup 19 is not powered on, and the spring 2 11 is not stretched.

[0030] The working steps are as follows: The staff holds the handle 3 and applies a forward force on the handle 3, so that the roller 2 starts to roll forward and drives the rectangular shell 1 to move horizontally. The staff pushes the rectangular shell 1 to multiple drilling directions of the mine.

[0031] The Auto-Reload Ammo component works as follows: When the loading shell 5 is placed in the sliding cavity 4, the spring 7 in the compressed state pushes the rubber plate 8 through the elastic stretching force, so that the rubber plate 8 slides horizontally on the groove 6 in the direction away from the spring 7, so that the rubber plate 8 pushes the multiple blasting detonators 9 to move synchronously, so that the blasting detonators 9 are blocked by the sliding column 13, and then the multiple blasting detonators 9 can be controlled by the sliding column 13 to enter the sliding cavity 10 one by one.

[0032] The setting of the automatic filling ammunition assembly enables the staff to avoid directly loading the blasting detonator 9 at the blasting site, greatly reducing the exposure time in the dangerous area. At the same time, it avoids the work steps of the staff constantly picking up the blasting detonator 9 for delivery, reducing the workload of the staff.

[0033] The working steps of the press-discharge assembly are as follows: At this time, the blasting detonator 9 closest to the sliding column 13 is resisted by the outer side of the sliding column 13, so that the rubber plate 18 can no longer push the blasting detonator 9 to slide on the groove 16 in the direction away from the spring 17. At the same time, the staff holds the pressing plate 12 and lifts the pressing plate 12 vertically upward. Therefore, the pressing plate 12 is subjected to a vertical upward force and moves vertically upward, stretching the spring 11, and the pressing plate 12 stretches the sliding column 13. At this time, the pressing plate 12 drives the sliding column 13 to slide vertically upward on the sliding cavity 10, so that the outer side of the sliding column 13 no longer resists the blasting detonator 9 closest to the sliding column 13. As mentioned above, the blasting detonator 9 at this time The blasting detonator 9 is pushed into the sliding cavity 10 by the rubber plate 8, and the staff no longer lifts the pressing plate 12 vertically upward. At this time, the pressing plate 12 moves vertically downward under the elastic contraction force of the spring 11. Therefore, the blasting detonator 9 closest to the sliding column 13 is affected by its own gravity and the thrust of the sliding column 13, so that the blasting detonator 9 slides vertically downward on the sliding cavity 10, and the bottom of the next blasting detonator 9 in the loading shell 5 conflicts with the upper surface of the rubber plate 22, so that the upper surface of the next blasting detonator 9 is conflicted by the vertical downward force of the sliding column 13, so that the next blasting detonator 9 will not leave the inner cavity of the loading shell 5.

[0034] The setting of the pressing and discharging assembly enables the staff to evenly place the blasting detonators 9 into the mine borehole by pressing the pressing plate 12, thereby achieving uninterrupted filling of ammunition and effectively reducing the interval time between placing two blasting detonators 9 each time.

[0035] The working steps of the limit assembly and the press-discharge assembly are as follows: At this time, the electric telescopic rod 21 begins to shrink after being energized, and the telescopic shaft end of the electric telescopic rod 21 drives the rubber plate 22 to slide horizontally on the groove 20 from the sliding cavity 10 to the direction close to the electric telescopic rod 21. Therefore, the upper surface of the rubber plate 22 no longer conflicts with the blasting detonator 9. At this time, the blasting detonator 9 is no longer limited by the rubber plate 22 and moves vertically downward. The blasting detonator 9 slides out of the guide tube 23 through the guide hole 24, and the sliding column 13 moves vertically downward due to the elastic contraction force of the spring 21, so that the outer side of the sliding column 13 again conflicts with the outer side of the next blasting detonator 9. At this time, the blasting detonator 9 finally passes through the guide tube 2 3 falls into the borehole of the mine. If the surface of the borehole is covered with slag to form an obstruction, the staff can press the pressing plate 12 and compress the spring 11, so that the sliding column 13 slides vertically downward and enters the interior of the guide hole 24. Therefore, the vertical downward force of the sliding column 13 pushes the blocked blasting detonator 9 vertically downward, so that the blasting detonator 9 can smoothly enter the borehole. When the staff no longer presses the pressing plate 12, the compressed spring 11 pushes the pressing plate 12 to move vertically upward through the elastic stretching force. Therefore, when the spring 11 returns to the initial state, the pressing plate 12 also returns to the initial state.

[0036] The depth measurement component works as follows: As described above, when the bottom of the blasting detonator 9 conflicts with the upper surface of the rubber plate 22, the electric suction cup 19 is energized to adsorb the top of the blasting detonator 9. When the limiting assembly no longer limits the blasting detonator 9, the vertical downward movement of the blasting detonator 9 drives the electric suction cup 19 to move synchronously. Therefore, the electric suction cup 19 moves vertically downward and pulls the soft tape measure 17. The soft tape measure 17 rotates continuously clockwise with the connection with the fixed block 14 as the center of the circle, so that the soft tape measure 17 drives the rotating disc 15 to rotate synchronously. Therefore, the rotating disc 15 contracts the torsion spring 16, so that the torsion spring 16 can also play a buffering role for the vertical downward movement of the blasting detonator 9. When the blasting detonator 9 is no longer vertically When it falls straight down into the borehole, the staff will add the scale on the soft tape measure 17 to the vertical length of the blasting detonator 9, so that the staff will record the depth of the borehole. If the depth of the borehole is too deep, it is necessary to pre-embed multiple blasting detonators 9. At this time, just repeat the above working steps. When the blasting detonators 9 in each borehole are pre-embedded, the electric suction cup 19 is powered off, and the torsion spring 16 rotates the rotating disc 15 in the opposite direction through the elastic stretching force. Therefore, the rotating disc 15 drives the soft tape measure 17 to recover the stretched part. At this time, the bottom of the soft tape measure 17 drives the electric suction cup 19 to move vertically upward, so that when the torsion spring 16 no longer stretches, the electric suction cup 19 returns to the starting position again.

[0037] The coordination of the limit assembly, the press-discharge assembly and the depth measuring assembly ensures that the blasting detonator 9 enters the borehole smoothly. At the same time, the rubber plate 22 prevents the blasting detonator 9 from being triggered by the direct vertical downward impact force of the blasting detonator 9. At the same time, pressing the pressing plate 12 can effectively prevent the blockage of the mine borehole from causing the blasting detonator 9 to be unable to enter. The electric suction cup 19 and the torsion spring 16 can buffer the vertical downward movement of the blasting detonator 9, further reducing the vertical downward impact force of the blasting detonator 9.

[0038] After the staff has pre-buried blasting detonators 9 in all the boreholes in the mine, the staff pushes the handle 3 again to transfer the rectangular housing 1 to a safe area. At the same time, the staff presses the detonation sensor 25, which controls the triggers inside the multiple blasting detonators 9, so that the multiple blasting detonators 9 blast the mine.

[0039] By setting up the depth measuring component, the depth of the borehole can be measured, thereby effectively ensuring the number of blasting detonators 9 placed by the staff. Drilling holes of different depths require a matching amount of explosives to achieve the ideal blasting effect and avoid the situation where there are too many blasting detonators 9 and the borehole is relatively shallow, and the strong shock wave and flying rocks generated by the explosion cause damage to the safety of surrounding personnel.

[0040] The provision of the roller 2 and the handle 3 can prevent the workers from directly contacting the blasting detonator 9, and at the same time facilitates the transportation of the blasting detonator 9 to the drilling area of ​​the mine.
