Description

Technical Field

[0001] The utility model relates to the technical field of mining blasting devices, in particular to a mining blasting device. Background Art

[0002] Blasting is a technology that uses the compression, loosening, destruction, throwing and killing effects of explosives in the air, water, soil and rock media or objects to achieve the desired purpose. When explosive bags or charges explode in soil and rock media or structures, the soil and rock media or structures will be compressed, deformed, destroyed, loosened and thrown. It is mainly used in earthwork engineering and the demolition of metal buildings and structures.

[0003] Through patent search, it is found that a mining rock blasting device with publication number CN211903943U is formed by bonding multiple independent blasting bodies with special adhesive to form a blasting body. The upper and lower ends of two adjacent independent blasting bodies are bonded to each other, so that each independent blasting body is detonated separately from each other, and the distance between the fuses of the blasting bodies is used to form an interval for the detonation of each independent blasting body. In this way, the release time of the explosive energy of the entire blasting device is slowed down, and the flying rocks generated during the blasting are reduced, reducing the safety hazards caused by the rock blasting. The blasting device has a simple structure, low cost, and wide practical value, but it cannot adjust the number of independent blasting bodies and the internal charge in real time according to the actual situation on site, and is relatively inconvenient to use. For this reason, we propose a mining blasting device to solve or improve the above problems. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-6 , including a cartridge 1, a ring-shaped positioning plate fixed at the bottom of the cartridge 1, a detonator 3 arranged on one side of the top of the cartridge 1, a detonator lead 7 inserted in the detonator 3, a sealing sheet 4 arranged on one side of the top of the detonator 3, a diameter of the sealing sheet 4 slightly smaller than a diameter of a slot at the top of the cartridge 1, a ring-shaped positioning plate fixed at the bottom of the sealing sheet 4, a tooth block 5 fixed on the top of the sealing sheet 4, a plurality of groups of tooth blocks 5 fixed on the top of the sealing sheet 4, an arc buckle 8 fixed to the cartridge 1 At the top, there are several groups of arc-shaped buckles 8 symmetrically on the top of the drug-loading cartridge 1, and the toothed grooves 6 are opened on the inner surface of the drug-loading cartridge 1. There are several groups of toothed grooves 6 on the inner surface of the drug-loading cartridge 1. The number of tooth blocks 5 is the same as the number of toothed grooves 6. When the sealing sheet 4 enters the interior of the drug-loading cartridge 1, the tooth blocks 5 will be engaged and connected with the toothed grooves 6, so that the tooth blocks 5 can relatively fix the position of the fixed sealing sheet 4 through the toothed grooves 6 to prevent the sealing sheet 4 from detaching from the interior of the drug-loading cartridge 1.

[0022] The arc-shaped card slot 10 is provided at the bottom of the drug-loading cartridge 1. The arc-shaped card slot 10 is provided at the bottom of the drug-loading cartridge 1 in several groups. The number of the arc-shaped card buckles 8 is the same as the number of the arc-shaped card slots 10. When it is necessary to combine several assembled drug cartridges 1 into a whole, the bottom of one assembled drug cartridge 1 is aligned with the top of another assembled drug cartridge 1, and the arc-shaped card buckle 8 is inserted into the inside of the arc-shaped card slot 10 and rotated so that the arc-shaped card buckle 8 and the arc-shaped card slot 10 can be engaged. At this time, the position of the arc-shaped card buckle 8 is relatively fixed, so that the position of the drug-loading cartridge 1 fixed with the arc-shaped card buckle 8 is relatively fixed. The same operation is repeated several times to combine several assembled drug cartridges 1 into a whole. The surface of the drug-loading cartridge 1 A protective plate 2 is fixed, and two groups of protective plates 2 are symmetrically fixed on the surface of the cartridge 1. A lead through hole 9 is opened on the surface of the cartridge 1 near the bottom side, and the lead through hole 9 is located between the two groups of protective plates 2. When the detonator 3 is located inside the cartridge 1, the detonator lead 7 can pass through the lead through hole 9, so that one end of the detonator lead 7 is located between the two groups of protective plates 2, which is convenient for unified wiring of the detonator lead 7 after charging is completed. The protective plate 2 can protect the detonator lead 7 to a certain extent, avoiding friction between the detonator lead 7 and the surface of the object when the detonator lead 7 is inserted into the object to be blasted after wiring is completed, thereby reducing or avoiding the problem of the detonator lead 7 falling off due to friction.

[0023] Working principle: when blasting is required, select the detonator 3 of appropriate size according to the situation of on-site investigation, and place it in the annular positioning groove set at the bottom of the charge barrel 1. After placement, pour the required amount of gunpowder into the inside of the charge barrel 1 to make it evenly distributed inside the charge barrel 1. After charging, place the sealing sheet 4 on the top of the charge barrel 1 and press it to make the sealing sheet 4 and the tooth block 5 enter the inside of the charge barrel 1. The tooth block 5 is engaged with the toothed slot 6 to relatively fix the position of the sealing sheet 4, so that the bottom of the sealing sheet 4 is pressed tightly against the top of the charge inside the charge barrel 1, thereby completing the customization of the charge amount. After the sealing sheet 4 is installed, the detonator 3 is located at the bottom of the sealing sheet 4 and the inside of the charge barrel 1. The inside of the annular positioning groove at the bottom can reduce or avoid the tipping over of the detonator 3 during transportation or placement, thereby improving the stability of the device. When it is necessary to combine several assembled cartridges 1 into a whole, the arc-shaped groove 10 at the bottom of one assembled cartridge 1 is aligned with the arc-shaped buckle 8 at the top of another assembled cartridge 1, and the arc-shaped buckle 8 is inserted into the inside of the arc-shaped groove 10 and one assembled cartridge 1 is rotated to make the arc-shaped buckle 8 engage with the arc-shaped groove 10, thereby combining the two assembled cartridges 1 into a whole. The above operation can be repeated multiple times to combine several assembled cartridges 1 into a whole, thereby solving the problem that the number of loaded cartridges 1 and the loading cannot be adjusted according to the on-site usage conditions, and the use is relatively convenient.
