Description

Technical Field

[0001] This invention relates to the field of mining technology, specifically to a blasting mining device. Background Technology

[0002] Blasting mining is a technique for extracting minerals by using explosives to break down ore or rock. This method is typically used for mining harder ores, such as metallic ores and coal. In blasting mining, explosives are placed in the ore or rock and then detonated to break it down. The broken ore or rock is removed and transported to a processing plant for further processing.

[0003] In existing patent literature, there is a patent application dated October 22, 2019, with authorization publication number CN 209524831 U entitled "A Blasting Device for Mining". This patent includes an alloy base plate and a detonator. The top of the alloy base plate is provided with an alloy shell, and the bottom of the alloy shell is provided with a sealing ring. The top of the alloy shell is provided with screws, reflective strips, and indicator lights, and the screws are fixedly connected to the alloy shell. Mounting plates are provided on both sides of the alloy base plate, and the mounting plates are fixedly connected to the alloy base plate. The top of the mounting plates is provided with expansion bolts, and the expansion bolts are movably connected to the mounting plates. The front of the alloy shell is provided with a dust cover, a groove, and an anti-collision device. The alloy shell has a slot, an explosive box, and a ring inside. The explosive box is fixed to the alloy base plate by the slot. The outer side of the explosive box has a buffer cotton and a fixing post. The buffer cotton and the explosive box are bonded together with adhesive. A detonator is provided on the front of the slot. A handle is provided on one side of the detonator. The front of the detonator has a heat dissipation hole and a terminal post. The heat dissipation hole is embedded in the front of the detonator. A support foot is provided at the bottom of the detonator. The explosive box contains grease, a vacuum insulation plate, and explosive particles.

[0004] However, this patent uses an electric wire to connect the detonator and the initiator for detonation triggering. The wired method requires the laying of electric wires, which is inconvenient for detonation. Moreover, if an emergency or accident occurs after detonation through the initiator and the detonator needs to be stopped, the initiator does not have a stop function, which may cause personal injury or property damage. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the above-mentioned background art by proposing a blasting mining device.

[0006] To achieve the above objectives, the invention provides the following technical solution: A blasting mining device includes a remote-controlled blasting tube and an infrared remote controller. The remote-controlled blasting tube is remotely activated or deactivated via the infrared remote controller. The remote-controlled blasting tube includes a gunpowder device, a detonation device, an ignition device, a control device, and a deactivation stop device. The gunpowder device, detonation device, ignition device, and control device are arranged sequentially from bottom to top. The deactivation stop devices are located on both sides of the detonation device.

[0007] By adopting the above scheme, in application, the remote-controlled blasting tube is remotely activated by an infrared remote controller. The infrared remote controller activates the control device, which ignites the detonator via an ignition device. The detonator then guides the explosive device to detonate. Simultaneously, the remote-controlled blasting tube is remotely activated and detonated by an infrared remote controller. The detonator is then extinguished in time by a detonation stop device to prevent detonation in case of emergency or accident, thereby avoiding blasting and thus preventing casualties or property damage.

[0008] As a further preferred embodiment, the gunpowder device includes a gunpowder tube, which has a double-layered tube structure and is filled with gunpowder.

[0009] By adopting the above scheme, the gunpowder tube has a double-layer tube structure, which can effectively avoid the compression of gunpowder during transportation, thereby improving its strength and ensuring its safety.

[0010] As a further preferred embodiment, the detonation device includes a wire winding post, which is fixed above and to the outside of the gunpowder tube. A wire is spirally wound on the wire winding post, and the wire is fixed from top to bottom by adhesive application. One end of the wire extends into the gunpowder tube.

[0011] By adopting the above method, the detonator is spirally wound around the detonator winding post, which can effectively extend the detonation time and reserve enough time to stop the detonation if it is necessary to stop the detonation.

[0012] As a further preferred embodiment, the ignition device includes a reference base, a through hole is provided in the middle of the reference base, a trigger pin is installed through the through hole, guide blocks are fixed on both sides of the trigger pin, the guide blocks are installed through a guide shaft, a limit head is fixed at the upper end of the guide shaft, and a reset spring located below the guide block is also fitted on the guide shaft. A flint is fixed below the trigger post, and a flint is fixed below the flint. The flint extends into the flint and rubs against the inner surface of the flint. Several ignition holes are opened on one side of the flint. A chuck is also installed on the side corresponding to the ignition hole. The chuck is mounted through the guide shaft. A spring is sleeved on the guide shaft. The other end of the lead wire held by the chuck is close to the ignition hole. A rotatable ignition trigger wheel is mounted above the trigger column. The surface of the ignition trigger wheel is provided with multiple evenly distributed trigger heads. The ignition trigger wheel is driven to rotate by a motor.

[0013] By adopting the above scheme, during ignition, the motor drives the ignition trigger wheel to rotate. During the rotation, the trigger head can press down against the ignition post, and then be reset by the return spring. This achieves up-and-down reciprocating movement, thereby causing flint one and flint two to continuously contact and rub against each other to generate sparks. The sparks will be generated at the ignition hole, which can ignite the fuse and thus achieve ignition.

[0014] As a further preferred embodiment, the control device includes a central processing unit (CPU), an infrared receiving module, and a battery, with the CPU serving as the signal processing center. The motor, the infrared receiving module, and the battery are electrically connected to the CPU.

[0015] As a further preferred embodiment, the detonation stop device includes an outer shell, an iron core fixed inside the outer shell, a coil wound around the iron core, the coil being electrically connected to a central processing unit, and guide seats being respectively mounted on the left and right sides of the lead winding column. A permanent magnet plate is fixed to the guide seat through a connecting plate, and the position of the permanent magnet plate corresponds to the position of the iron core. The surface of the guide seat is fixed with multiple inflatable thin airbags arranged side by side from top to bottom, and the inflatable thin airbags are filled with flame retardant powder.

[0016] By adopting the above scheme, when the detonation stop device is not triggered, the permanent magnet will be attracted and fixed to the iron core. At this time, the inflatable thin airbag is far from the fuse, and the burning fuse will not damage the inflatable thin airbag. When the detonation stop device is triggered, the central processing unit controls the supply of power to the coil. At this time, the iron core and the coil form an electromagnet, and its magnetism is exactly opposite to the magnetism of the permanent magnet, thereby pushing the inflatable thin airbag closer to the burning fuse. The sparks will burn the inflatable thin airbag at the corresponding position. At this time, the flame retardant powder inside the inflatable thin airbag will extinguish the burning fuse, thereby stopping the detonation.

[0017] As a further preferred embodiment, the infrared remote controller includes a switch control component, a second central processing unit, an infrared emitting module, and a second battery. The second central processing unit serves as the signal processing center, and the switch control component, the infrared emitting module, and the second battery are electrically connected to the second central processing unit. The switch control assembly includes an explosion start switch and an explosion stop switch.

[0018] As a further preferred embodiment, the upper end of the trigger post is an arc-shaped head, and the surface of the trigger head is an arc-shaped surface.

[0019] By adopting the above solution, the friction between the two can be reduced, making the triggering process smoother.

[0020] As a further preferred embodiment, the inflatable thin airbag is semi-circular, and the two inflatable thin airbags can form a complete circular inflatable thin airbag, completely surrounding the lead wire.

[0021] By adopting the above solution, no matter where the fuse burns, the spark will burn through the corresponding inflatable thin airbag. At this time, the flame retardant powder inside the inflatable thin airbag will extinguish the burning fuse, thus ensuring effective extinguishing.

[0022] As a further preferred embodiment, the inflatable thin airbag is also filled with air, and the atmospheric pressure inside the inflatable thin airbag is higher than the standard atmospheric pressure.

[0023] By adopting the above method, since the atmospheric pressure inside the inflatable thin airbag is higher than the standard atmospheric pressure, when it is burned out, the flame retardant powder will be sprayed out evenly under the action of atmospheric pressure, which can expand the extinguishing range and ensure successful extinguishing.

[0024] The beneficial effects of the invention compared to existing technologies are as follows: It uses infrared remote control to remotely initiate the explosion, which is more flexible and free during detonation and greatly ensures the safety during blasting. By installing a detonation stop device, the detonation can be stopped in time in case of emergency or accident, thereby avoiding explosion and thus preventing casualties or property damage.

Detailed Implementation

[0027] The technical solutions of the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the invention.

[0028] Please refer to Figure 1-10 The present invention provides a technical solution: A blasting mining device includes a remote-controlled blasting tube and an infrared remote controller. The remote-controlled blasting tube is remotely activated or deactivated via the infrared remote controller. The remote-controlled blasting tube includes a gunpowder device 1, a detonating device 2, an ignition device 3, a control device 4, and a deactivation stop device 5. The gunpowder device 1, detonating device 2, ignition device 3, and control device 4 are arranged sequentially from bottom to top. The deactivation stop device 5 is located on both sides of the detonating device 2.

[0029] In application, the remote-controlled blasting tube is remotely activated by an infrared remote controller. The infrared remote controller activates the control device 4, which ignites the detonating device 2 via the ignition device 3. The detonating device 2 guides the explosive device 1 to blast. At the same time, the remote-controlled blasting tube is remotely activated by the infrared remote controller to stop the explosion. The detonation stop device 5 extinguishes the detonating device 2 in time to prevent blasting in case of emergency or accident, thereby avoiding casualties or property damage.

[0030] The gunpowder device 1 includes a gunpowder tube 6, which has a double-layer tube structure and is filled with gunpowder 7.

[0031] The gunpowder tube 6 has a double-layer tube structure, which can effectively prevent the gunpowder 7 from being squeezed during transportation, thereby improving its strength and ensuring its safety.

[0032] The detonation device 2 includes a lead wire winding post 8, which is fixed to the upper outer side of the gunpowder tube 6. A lead wire 9 is spirally wound on the lead wire winding post 8. The lead wire 9 is fixed from top to bottom by applying adhesive. One end of the lead wire 9 extends into the gunpowder tube 6.

[0033] By spirally winding the detonator 9 onto the detonator winding post 8, the detonation time can be effectively extended, allowing sufficient time to stop the detonation should it need to be stopped.

[0034] The ignition device 3 includes a reference base 10, with a through hole 11 through the middle of the reference base 10. A trigger pin 12 is installed through the through hole 11. Guide blocks 13 are fixed on both sides of the trigger pin 12. The guide blocks 13 are installed through the guide shaft 14. A limit head 15 is fixed at the upper end of the guide shaft 14. A reset spring 16 located below the guide block 13 is also installed on the guide shaft 14. A flint 17 is fixed below the trigger post 12, and a flint 28 is fixed below the flint 17. The flint 17 extends into the interior of the flint 28 and rubs against the inner surface of the flint 28. Several ignition holes 19 are opened on one side of the flint 28. A chuck 20 is also installed on the corresponding side of the ignition hole 19. The chuck 20 is mounted through the guide shaft 21. A spring 22 is sleeved on the guide shaft 21. The chuck 20 holds the other end of the lead wire 9 close to the ignition hole 19. A rotatable ignition trigger wheel 23 is mounted above the trigger post 12. The surface of the ignition trigger wheel 23 is provided with a plurality of evenly distributed trigger heads 24. The ignition trigger wheel 23 is driven to rotate by a motor 25.

[0035] During ignition, the motor 25 drives the ignition trigger wheel 23 to rotate. During the rotation, the trigger head 24 presses down against the ignition post 12 and is then reset by the return spring 16, thus achieving up-and-down reciprocating movement. This causes the flint one 17 and flint two 18 to continuously contact and rub against each other, generating a spark. The spark is generated at the ignition hole 19, which can ignite the fuse 9, thus achieving ignition.

[0036] The control device 4 includes a central processing unit 26, an infrared receiving module 27, and a battery 28. The central processing unit 26 serves as the signal processing center, and the motor 25, the infrared receiving module 27, and the battery 28 are electrically connected to the central processing unit 26.

[0037] The detonation stop device 5 includes an outer shell 29, an iron core 30 fixed inside the outer shell 29, a coil 31 wound around the iron core 30, the coil 31 being electrically connected to a central processing unit 26, and guide seats 32 respectively mounted on the left and right sides of the lead winding column 8. The guide seats 32 are fixed with permanent magnet pieces 34 through connecting plates 33, and the position of the permanent magnet pieces 34 corresponds to the position of the iron core 30. The surface of the guide seat 32 is fixed with multiple inflatable thin airbags 35 arranged side by side from top to bottom, and the inflatable thin airbags 35 are filled with flame retardant powder 36.

[0038] When the detonation stop device 5 is not triggered, the permanent magnet 34 will be attracted and fixed to the iron core 30. At this time, the inflatable thin airbag 35 is far away from the fuse 9, and the burning fuse 9 will not damage the inflatable thin airbag 35. When the detonation stop device 5 is triggered, the central processing unit 26 controls the power supply to the coil 31. At this time, the iron core 30 and the coil 31 form an electromagnet, and its magnetism is exactly opposite to the magnetism of the permanent magnet 34, thereby pushing the inflatable thin airbag 35 closer to the burning fuse 9. The sparks will burn the inflatable thin airbag 35 at the corresponding position. At this time, the flame retardant powder 36 inside the inflatable thin airbag 35 will extinguish the burning fuse 9, thereby stopping the detonation.

[0039] The infrared remote controller includes a switch control component 37, a central processing unit 38, an infrared emitting module 39, and a battery 40. The central processing unit 38 serves as the signal processing center, and the switch control component 37, the infrared emitting module 39, and the battery 40 are electrically connected to the central processing unit 38. The switch control component 37 includes an activation explosion switch and a deactivation explosion switch.

[0040] In the above description, the upper end of the trigger post 12 is an arc-shaped head, and the surface of the trigger head 24 is an arc-shaped surface. This reduces the friction between the two, resulting in a smoother triggering process.

[0041] As described above, the inflatable thin airbag 35 is semi-circular, and two inflatable thin airbags 35 can form a complete circular inflatable thin airbag, completely surrounding the fuse 9. At this time, no matter where the fuse 9 burns, the sparks will burn through the corresponding inflatable thin airbag 35. At this time, the flame retardant powder 36 inside the inflatable thin airbag 35 will extinguish the burning fuse 9, thereby ensuring effective extinguishing.

[0042] As described above, the inflatable thin airbag 35 is also filled with air, and the atmospheric pressure inside the inflatable thin airbag 35 is higher than the standard atmospheric pressure. Because the atmospheric pressure inside the inflatable thin airbag 35 is higher than the standard atmospheric pressure, when it is burned out, the flame retardant powder 36 will be evenly sprayed out under the action of atmospheric pressure, which can expand the extinguishing range and ensure successful extinguishing.

[0043] Working principle of the invention: In application, a hole is drilled at the location in the mountain to be blasted, and then a remote-controlled blasting tube is inserted into the hole. The blast is then started or stopped by an infrared remote control.

[0044] At the time of detonation, the activation detonation switch in the switch control component 37 is pressed. At this time, the infrared emitting module 39 feeds back the infrared signal to the infrared receiving module 27, and then the central processing unit 26 controls the motor 26 to start, thereby igniting. The motor 25 drives the ignition trigger wheel 23 to rotate. During the rotation, the trigger head 24 can press down on the trigger post 12, and then reset by the return spring 16, thereby realizing the up and down reciprocating movement, thereby driving the flint 17 and flint 2 18 to continuously contact and rub against each other, generating sparks. The sparks will be generated at the ignition hole 19, which can ignite the fuse 9, thereby achieving ignition. At this time, since the detonation stop device 5 is not triggered, the permanent magnet 34 will be attracted and fixed on the iron core 30. At this time, the inflatable thin air bag 35 is far away from the fuse 9, and the burning fuse 9 will not damage the inflatable thin air bag 35. Then the fuse 9 gradually burns until it enters the gunpowder tube 6, and the gunpowder 7 is ignited, realizing blasting mining.

[0045] In case of emergency or accident, detonation should be stopped immediately to avoid explosion and thus prevent casualties or property damage. To stop detonation, press the stop explosion switch in the switch control component 37. At this time, the infrared emitting module 39 feeds back the infrared signal to the infrared receiving module 27, and then the central processing unit 26 controls the energization of the coil 31. At this time, the iron core 30 and the coil 31 form an electromagnet, and its magnetism is exactly opposite to the magnetism of the permanent magnet sheet 34, thereby pushing the inflatable thin airbag 35 close to the burning fuse 9. The sparks will burn the inflatable thin airbag 35 at the corresponding position. Since the atmospheric pressure inside the inflatable thin airbag 35 is higher than the standard atmospheric pressure, when it is burned, the flame retardant powder 36 will be evenly sprayed out under the action of atmospheric pressure, which can expand the extinguishing range and ensure successful extinguishing, thereby stopping the detonation.

[0046] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
