Description

Technical Field

[0001] This utility model relates to the field of explosive charging technology, specifically to an explosive charging structure for blasting operations in open-pit mine voids. Background Technology

[0002] Open-pit goaf refers to the unfilled space left after ore or rock has been excavated and removed during open-pit mining. These goafs are usually caused by layered mining, bench mining, or other mining methods, and may form large spaces or depressions. When blasting open-pit goafs, charging structures are typically used to quickly complete the loading task. A blasting charging structure is a specialized device or tool used to load explosives into blast holes or other predetermined locations. Through efficient charging devices, blasting preparation time is shortened, mining progress is accelerated, and the time and labor required for manual charging are reduced.

[0003] In existing technologies, when blasting open-pit mine voids using a charging structure, the explosives cannot be properly compacted after being filled into the blast holes. This results in insufficient compaction of the explosives, which may lead to a loose distribution of the explosives within the blast holes. Consequently, the charging quality and blasting effect cannot be effectively improved. Therefore, to address these issues, a new charging structure for blasting operations in open-pit mine voids is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a blasting charge structure for open-pit mine voids, in order to solve the problem mentioned in the background art that the explosives cannot be properly compacted, resulting in insufficient compaction of the charge and looseness of the explosives in the blast hole, thus failing to improve the charge quality and ensure the blasting effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a blasting charging structure for open-pit mine voids, comprising a base, a support frame fixedly connected to the upper surface of the base, a cartridge fixedly connected to the inner side of the support frame, an inlet pipe fixedly connected to the top of the cartridge, an outlet pipe fixedly connected to the bottom of the cartridge, a telescopic cylinder fixedly installed on the inner surface of the base, a connecting plate fixedly connected to the output end of the telescopic cylinder, a connecting pipe fixedly connected to the inner side of the connecting plate, both the connecting plate and the connecting pipe being movable on the surface of the outlet pipe, the connecting plate being movable inside the support frame, a through groove being opened on the inner side of the base, and the connecting pipe being movable inside the through groove;

[0006] The inner side of the support frame is provided with a pressing mechanism, which includes a screw rod that is movably connected to the inner side of the support frame. A first motor is fixedly installed at the top of the support frame. A sleeve rod is threadedly connected to the surface of the screw rod, and a pressure block is fixedly connected to the bottom end of the sleeve rod.

[0007] Preferably, the pressing mechanism further includes a limiting block, which is fixedly connected to the surface of the sleeve rod, and a connecting block is fixedly connected to the upper surface of the base, with a limiting groove formed on the inner side of the connecting block.

[0008] Preferably, the screw is fixedly connected to the output end of the first motor, and the limiting blocks are fixedly connected in two sets on both sides of the sleeve rod.

[0009] Preferably, the sleeve rod, pressure block, and limiting block are all movably located inside the base, and the sleeve rod and limiting block are movably connected to the limiting groove and the connecting plate.

[0010] Preferably, the inner side of the cartridge is provided with an anti-clogging mechanism, the anti-clogging mechanism including a rotating rod, the rotating rod being movably connected to the inner side of the cartridge, a second motor being fixedly installed at the top of the cartridge, a connecting rod being fixedly connected to the surface of the rotating rod, a fixing plate being fixedly connected to the inner wall of the cartridge, and a spiral conveying rod being movably connected to the inner side of the fixing plate.

[0011] Preferably, the rotating rod and the output end of the second motor are fixedly connected, the spiral conveying rod and the rotating rod are fixedly connected, and the spiral conveying rod is movable inside the medicine discharge pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By driving the screw to rotate through the first motor, the sleeve rod can drive the pressure block to move vertically under the action of the first motor. The vertical movement of the pressure block can press down the explosive in the blast hole, thereby making the explosive flat and preventing it from being too loose in the blast hole. This can improve the loading effect and quality, facilitate better blasting operations, and help improve blasting performance.

[0014] 2. The second motor drives the rotating rod to rotate, causing the connecting rod and the screw conveyor rod to rotate accordingly. The rotation of the connecting rod disperses the explosives, preventing them from clumping together and accumulating inside the cartridge, thus avoiding blockages in the cartridge and discharge pipe. The rotation of the screw conveyor rod transports the explosives and clears the discharge pipe, further preventing blockages and ensuring stable discharge of the explosives, thereby guaranteeing the continuity of the loading process.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 One embodiment provided by this utility model:

[0022] The telescopic cylinder 15, the first motor 21, and the second motor 31 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0023] A blasting charging structure for open-pit mine voids includes a base 1. A support frame 11 is fixedly connected to the upper surface of the base 1. A cartridge 12 is fixedly connected to the inner side of the support frame 11. An inlet pipe 13 is fixedly connected to the top of the cartridge 12, and a discharge pipe 14 is fixedly connected to the bottom of the cartridge 12. A telescopic cylinder 15 is fixedly installed on the inner surface of the base 1. A connecting plate 16 is fixedly connected to the output end of the telescopic cylinder 15. A connecting pipe 17 is fixedly connected to the inner side of the connecting plate 16. Both the connecting plate 16 and the connecting pipe 17 are movable on the surface of the discharge pipe 14. The connecting plate 16 is movable on the support frame 1. Inside the base 1, a through groove 18 is provided. The connecting pipe 17 moves inside the through groove 18. The base 1 allows the entire device to be moved, making it easy to move the connecting pipe 17 above the borehole. The extension of the telescopic cylinder 15 allows the connecting plate 16 to drive the connecting pipe 17 down, thereby allowing the connecting plate 16 and the connecting pipe 17 to move on the surface of the discharge pipe 14, so that the connecting pipe 17 enters the borehole. The charging pipe 13 allows the explosive to enter the cartridge 12 for storage. The explosive can enter the borehole through the discharge pipe 14 and the connecting pipe 17, thus completing the charging.

[0024] A pressing mechanism is provided on the inner side of the support frame 11. The pressing mechanism includes a screw 2, which is movably connected to the inner side of the support frame 11. A first motor 21 is fixedly installed on the top of the support frame 11. A sleeve 22 is threadedly connected to the surface of the screw 2. A pressure block 23 is fixedly connected to the bottom end of the sleeve 22. By setting the sleeve 22, the sleeve 22 can drive the pressure block 23 to move vertically during the rotation of the first motor 21. This facilitates the pressing of the explosives filled in the borehole by the pressure block 23, making the explosives more compact and thus improving the loading effect and the blasting quality.

[0025] Furthermore, the pressing mechanism also includes a limiting block 24, which is fixedly connected to the surface of the sleeve rod 22. A connecting block 25 is fixedly connected to the upper surface of the base 1. A limiting groove 26 is opened on the inner side of the connecting block 25. By setting the limiting block 24 and opening the limiting groove 26, the sleeve rod 22 can be limited, which can prevent the sleeve rod 22 from shifting under the action of the first motor 21, thereby ensuring the stable lifting and lowering of the pressing block 23.

[0026] Furthermore, the screw 2 and the output end of the first motor 21 are fixedly connected, and the limiting blocks 24 are fixedly connected in two sets on both sides of the sleeve rod 22. The first motor 21 drives the screw 2 to rotate, which enables the sleeve rod 22 to drive the pressure block 23 to move vertically. In turn, the pressure block 23 continuously rises and falls, which facilitates pressing down the explosive in the borehole and flattening the explosive.

[0027] Furthermore, the sleeve rod 22, the pressure block 23, and the limiting block 24 are all movable inside the base 1. The sleeve rod 22 and the limiting block 24 are movably connected to the limiting groove 26 and the connecting plate 16. Through the opening of the limiting groove 26, when the sleeve rod 22 drives the pressure block 23 to move vertically under the action of the first motor 21, the lifting and lowering movement of the sleeve rod 22 can be guaranteed.

[0028] Furthermore, an anti-blocking mechanism is provided on the inner side of the cartridge 12. The anti-blocking mechanism includes a rotating rod 3, which is movably connected to the inner side of the cartridge 12. A second motor 31 is fixedly installed at the top of the cartridge 12. A connecting rod 32 is fixedly connected to the surface of the rotating rod 3. A fixing plate 33 is fixedly connected to the inner wall of the cartridge 12. A spiral conveying rod 34 is movably connected to the inner side of the fixing plate 33. The rotating rod 3 is driven to rotate by the second motor 31, which allows the connecting rod 32 to rotate under the action of the rotating rod 3. This facilitates the breaking up of agglomerated explosives through the connecting rod 32, preventing the accumulation of agglomerated explosives and thus preventing blockage of the explosives in the cartridge 12 or the discharge pipe 14.

[0029] Furthermore, the output end of the rotating rod 3 and the second motor 31 are fixedly connected, and the spiral conveying rod 34 is fixedly connected to the rotating rod 3. The spiral conveying rod 34 is movable inside the discharge pipe 14. By setting the spiral conveying rod 34, when the rotating rod 3 rotates, the spiral conveying rod 34 rotates accordingly, which can realize the conveying of explosives, making it easier for the explosives to be stably discharged and enter the borehole.

[0030] Working principle: In use, after the explosive is loaded through the connecting pipe 17, the base 1 is moved so that the bottom of the pressure block 23 faces the borehole. The first motor 21 is electrically connected to an external power source. The operator starts the first motor 21 by pressing the switch. The first motor 21 drives the screw 2 to rotate. The sleeve 22 is limited by the limiting block 24 and the limiting groove 26. Under the action of the first motor 21, it drives the pressure block 23 to move vertically, so that the sleeve 22 and the limiting block 24 can move inside the connecting plate 16 and the limiting groove 26. At the same time, the sleeve 22, the pressure block 23 and the limiting block 24 move inside the base 1. By continuously lowering the pressure block 23, the explosive in the borehole is pressed down, which can flatten the explosive.

[0031] The second motor 31 is electrically connected to an external power source. The operator starts the second motor 31 by pressing a switch. The operation of the second motor 31 drives the rotating rod 3 to rotate. The connecting rod 32 and the screw conveyor rod 34 will rotate under the action of the rotating rod 3. The rotation of the connecting rod 32 can disperse the explosive in the cartridge 12 to prevent the explosive from clumping. The rotation of the screw conveyor rod 34 can transport the explosive and clear the discharge pipe 14.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
