Description

Technical Field

[0001] The invention relates to the technical field of blasting devices, in particular to an explosive box for mine blasting which is convenient for fixing explosives. Background Art

[0002] In today's mining industry, blasting operations are an extremely critical and indispensable link. With the continuous growth of demand for mineral resources, the scale of mining is expanding, and the frequency and complexity of blasting operations are also continuing to increase. Under such a development trend, the safe storage and transportation of explosives, as the core energy source of blasting operations, has become increasingly important. At present, the common mine blasting explosive boxes on the market have played a certain role in ensuring the safety of explosives.

[0003] However, there are still many shortcomings in the existing explosive boxes. Most explosive boxes lack an effective fixed structure. During the transportation or handling of explosives, especially on the complex and rugged roads in the mine, the bumps of the vehicle can easily cause the explosives to roll and collide in the box. This unstable state may not only damage the explosive packaging, but more seriously, it greatly increases the risk of accidental explosion, posing a huge threat to the safety of personnel and mine facilities. In addition, the internal space layout of the explosive box is generally single, mostly a large overall space, which is difficult to store and classify according to the different sizes and specifications of the explosives. The explosives are easy to scatter in the box, which is inconvenient to use, seriously affecting the efficient development of blasting operations. In addition, the mine environment is complex and changeable, and the humidity is unstable. The moisture-proof performance of the existing explosive boxes is often unsatisfactory. Once the explosives are damp, their performance will be significantly reduced, such as the reduction of explosion power and the reduction of detonation reliability, which not only affects the blasting effect, but also may cause serious safety accidents.

[0004] Based on this, the present invention designs an explosive box for mine blasting which is convenient for fixing explosives to solve the above problems. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art and provide an explosive box for mine blasting which is convenient for fixing explosives.

[0006] The technical solution adopted to solve the above technical problems is:

[0007] An explosive box for mine blasting that is convenient for fixing explosives, comprising a shell assembly, a monomer storage assembly for storing emulsion explosives separately installed in the shell assembly, a closing assembly for closing the monomer storage assembly installed on the monomer storage assembly, the closing assembly cooperates with the monomer storage assembly to fix the emulsion explosive, and an ion fan for removing static electricity is installed in the shell assembly;

[0008] The monomer storage assembly includes a storage shell assembly and a splicing assembly. The storage shell assembly and the splicing assembly are both provided with multiple groups. The storage shell assembly is connected with the shell assembly and the closing assembly. The splicing assembly is connected with the storage shell assembly. Two groups of storage shell assemblies can be connected via the splicing assembly.

[0009] Through the above technical scheme, emulsion explosives can be stored separately through storage shell assemblies. Each group of emulsion explosives is individually protected by a splicing assembly and a closing assembly. Different batches or types of emulsion explosives may have performance differences. Separate storage and protection can avoid their mutual contact, friction and collision. Two groups of storage shell assemblies can be combined through a splicing assembly. When taking them out, the required number of storage shell assemblies can be combined together through the splicing assembly according to actual storage and use needs, and can be flexibly adjusted to facilitate transportation during use. At the same time, the static electricity generated at the inner end of the shell assembly can be eliminated through the ion fan to prevent explosion.

[0010] Furthermore, the shell assembly includes a mounting shell, a cover plate, a mounting frame and a placement frame. The rear end of the cover plate is hinged to the upper end of the rear side panel of the mounting shell. The mounting frame is provided with two groups of symmetrically fixedly mounted on the left and right inner walls of the mounting shell. The ion blower is fixedly mounted on the left side wall of the mounting shell. The front and rear end faces of the placement frame are respectively fixedly connected to the front and rear inner walls of the mounting shell.

[0011] Furthermore, a plurality of groups of first ventilation grooves are provided on the inner side wall of the mounting frame at equal intervals from front to back.

[0012] Through the above technical solution, a desiccant is placed at the inner end of the mounting frame, and air circulation is facilitated through the first ventilation groove to increase the drying effect, while the wind from the ion fan effectively improves the drying effect.

[0013] Furthermore, the storage shell assembly includes a placement shell, a first spring and a placement base plate. The bottom surface of the placement shell is fitted and connected to the bottom surface of the mounting shell, and the placement shell is connected to the closing assembly. The first spring is circumferentially arranged in four groups. The lower end of the first spring is fixedly connected to the inner bottom surface of the placement shell, the upper end of the first spring is fixedly connected to the bottom surface of the placement base plate, and the outer wall of the placement base plate is limitedly slidably connected to the inner wall of the placement shell.

[0014] Furthermore, four groups of second ventilation grooves are provided at equal intervals in the circumferential direction on the outer side wall of the housing.

[0015] Through the above technical solution, the bottom surface of the storage shell assembly is provided with a first spring and a placement bottom plate to increase the buffering effect on the emulsion explosive, thereby reducing the impact on the emulsion explosive.

[0016] Furthermore, the splicing assembly includes a splicing plug-in block, a splicing card block, a limiting hole, a pin rod, a third spring and a limiting block. The splicing plug-in block and the splicing card block are respectively provided in two groups, and the two groups of splicing plug-ins and the two groups of splicing card blocks are respectively fixedly installed on the outer wall of the shell, and the two groups of splicing plug-ins are vertically arranged between them, and the two groups of splicing card blocks are vertically arranged between them, and the splicing plug-ins are used in conjunction with the splicing card blocks for clamping.

[0017] Furthermore, a limiting hole for cooperating with the pin rod plug-in is provided on the outer side wall of the lower end of each group of the splicing blocks, and a group of limiting holes, a pin rod, a third spring, and a limiting block are provided at the lower end of each group of the splicing blocks. The pin rod is slidingly connected to the placement shell, and the inner end face of the pin rod is in contact with the outer side wall of the limiting block. The outer end of the third spring is fixedly connected to the inner side wall of the lower end of the placement shell, and the inner end of the third spring is fixedly connected to the outer side face of the button at the inner end of the pin rod, and the limiting block is fixedly installed on the lower end face of the bottom plate of the placement shell.

[0018] Through the above technical solution, the splicing block is clamped with the splicing card block and then limited by the pin rod cooperating with the limiting hole on the splicing block. The lower end of the splicing block is a bevel that fits the bevel on the outside of the pin rod for sliding, which makes it easy for the splicing block to drive the pin rod to retract.

[0019] Furthermore, the placement rack is provided with a plurality of slots, and the slots are used for plugging in a combination of a placement housing, a splicing plug-in block, and a splicing card block.

[0020] Through the above technical solution, the combination of the placement shell, the splicing plug-in block, and the splicing card block is placed on the placement rack through the slot, so that the combination of the placement shell, the splicing plug-in block, and the splicing card block is easy to take and place. When taking it out, the required number of placement shells can be combined together through the splicing plug-in block and the splicing card block according to actual storage and use needs, and it can be flexibly adjusted to facilitate transportation during use.

[0021] Furthermore, the closing assembly includes a pressure plate, a connecting plate, a second spring, a closing cover, a slot and a limiting rod.

[0022] Through the above technical scheme, by placing the shell on the closing component cover, the pressure plate contacts the upper end surface of the emulsion explosive. When the closing cover is rotated, the pressure plate and the connecting plate rotate without generating friction to the emulsion explosive. At the same time, the emulsion explosive is completely fixed and buffered by the action force of the second spring and the action force of the first spring. In the process of the closing cover being combined with the placing shell, the closing cover drives the limiting rod to move downward from the vertical connecting groove of the slot, and then rotates toward the vertical non-connecting groove along the horizontal groove of the slot, and then reaches the vertical non-connecting groove of the slot to release the closing cover. Under the action force of the second spring, the limiting rod is clamped at the upper end of the vertical non-connecting groove of the slot to complete the closure.

[0023] The beneficial effects of the present invention are as follows: (1) the emulsion explosives are stored separately through the storage shell assembly, and each group of emulsion explosives is individually protected by the splicing assembly and the sealing assembly. Different batches or types of emulsion explosives may have performance differences. Separate storage and protection can avoid their mutual contact, friction and collision; (2) two groups of storage shell assemblies can be combined through the splicing assembly. When taking out, the required number of storage shell assemblies can be combined together according to actual storage and use requirements through the splicing assembly, and flexible adjustment is convenient for transportation during use; (3) static electricity generated at the inner end of the shell assembly is eliminated by the ion fan to prevent explosion. At the same time, a desiccant is placed at the inner end of the mounting frame. The first ventilation groove facilitates air circulation to increase the drying effect. At the same time, the wind from the ion fan effectively improves the drying effect. BRIEF DESCRIPTION OF THE DRAWINGS
