[0019] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Example:

[0021] A blast hole charging structure, such as Figures 1 to 3 As shown, it includes a plurality of coaxially arranged drug-filled cartridges, and adjacent drug-filled cartridges are bonded with a telescopic rod together. The drug-filled cartridges include an upper cover plate 101, a lower cover plate 102 and four limit posts 103. The four limit posts 103 are arranged in a circular array between the upper cover plate 101 and the lower cover plate 102. The two ends of the telescopic rod are respectively bonded to the end surfaces of the upper cover plate 101 and the lower cover plate 102. The top and bottom surfaces of the limit posts 103 are bonded with sliders 2. The end surfaces of the upper cover plate 101 and the lower cover plate 102 that are close to each other are provided with slide grooves 3 for the slider 2 to slide. The slider 2 is provided with fixing members for fixing the limit posts 103 relatively to the upper cover plate 101 and the lower cover plate 102 respectively. The fixing members are plastic bolts 2 6. The slider 2 is provided with threaded holes 2 that are interconnected with the slide groove 3. One end of the plastic bolt 2 6 is threadedly connected in the threaded hole 2 and pressed against the inner wall of the slide groove 3.

[0022] When carrying out some larger-scale blasting operations, a deeper blasting hole is first drilled with a drilling device. When multiple explosives are placed in multiple charge cartridges, the user's hand first passes through the gap between two of the limit columns 103 and removes the plastic bolt 6 near the upper cover plate 101, so that the plastic bolt 6 is disengaged from the threaded hole 2 on the slider 2 near the top surface of the limit column 103. At this time, one end of the plastic bolt 6 near the lower cover plate 102 is still threadedly connected to the threaded hole 2 on the slider 2 on the bottom surface of the limit column 103, and contacts the inner wall of the slide groove 3 of the lower cover plate 102. The upper cover plate 101 can then be disassembled. At this time, the slider 2 located on the top surface of the limit column 103 is separated from the inner wall of the slide groove 3 of the upper cover plate 101. The explosives can then be placed between the four limit columns 103, and the upper cover plate 101 can then be installed so that the slider 2 located on the top surface of the limit column 103 is disengaged from the inner wall of the slide groove 3 of the upper cover plate 101. 3, the slider 2 on the top surface is fitted with the inner wall of the slide groove 3 on the upper cover plate 101, and then one end of the plastic bolt 2 is threadedly connected to the threaded hole 2 on the slider 2 located on the top surface of the limiting column 103 and pressed against the inner wall of the slide groove 3 of the upper cover plate 101. At this time, the explosives are respectively fitted with the bottom surface of the upper cover plate 101, the top surface of the lower cover plate 102 and the outer walls of the four limiting columns 103. Then, the telescopic rod is extended to increase the distance between two adjacent charge cartridges, and the telescopic rod is contracted to shorten the distance between two adjacent charge cartridges, so that there is a distance between two adjacent charge cartridges and the two adjacent explosives will not be directly stacked. After adjusting the distance between two adjacent charge cartridges by telescoping the telescopic rod, multiple charge cartridges, the telescopic rod and the explosives are put into the blasting hole together, thereby reducing the situation where multiple explosives are directly put into the blasting hole, resulting in the stacking of explosives and affecting the blasting effect.

[0023] like Figures 1 to 3 As shown, the telescopic rod includes a connecting tube 401 and a connecting rod 402 slidably connected in the connecting tube 401, the connecting tube 401 is bonded to the top surface of the upper cover plate 101, and the connecting rod 402 is bonded to the bottom surface of the lower cover plate 102. A positioning member for relatively fixing the two is provided between the connecting tube 401 and the connecting rod 402, and the positioning member is a plastic bolt 5. A threaded hole 1 is provided on the outer wall of the connecting tube 401, and one end of the plastic bolt 5 is threadedly connected in the threaded hole 1 and pressed against the outer wall of the connecting rod 402. When multiple explosives are placed in multiple charge cartridges respectively, the connecting rod 402 is first slid. At this time, the connecting rod 402 on the lower cover plate 102 on one of the drug cartridges is slidably connected to the connecting tube 401 on the upper cover plate 101 of the other drug cartridge. When the connecting rod 402 slides, it drives the lower cover plate 102, the upper cover plate 101, the explosive and the four limit columns 103 on the connecting rod 402 to move. When the distance between two adjacent drug cartridges is adjusted to the distance required by the user by sliding the connecting rod 402, one end of the plastic bolt 5 is threadedly connected to the threaded hole 1 and pressed against the outer wall of the connecting rod 402, thereby improving the stability of the connecting rod 402 in the connecting tube 401.

[0024] like Figures 1 to 3 As shown, the cross section of the slider 2 is T-shaped. When the diameters of the drilled blasting holes are different and different sizes of explosives need to be used, the user's hand first passes through the gap between two of the limit posts 103, and removes the plastic bolts 6 on the slider 2 located on the top surface of the limit post 103 and the plastic bolts 6 on the slider 2 located on the bottom surface of the limit post 103, and then holds and slides the limit post 103, and the limit post 103 is simultaneously driven to slide the top surface of the limit post 103. The slider 2 on the top of the limiting column 103 and the slider 2 on the bottom of the limiting column 103 move, at this time, the slider 2 located on the top of the limiting column 103 slides in the slide groove 3 of the upper cover 101, and the slider 2 located on the bottom of the limiting column 103 slides in the slide groove 3 of the lower cover 102, and then one end of the plastic bolt 2 6 close to the upper cover 101 passes through the threaded hole 2 on the slider 2 on the top of the limiting column 103 and is pressed against the inner wall of the slide groove 3 of the upper cover 101, and passes through One end of the plastic bolt 26 near the lower cover plate 102 is threadedly connected to the threaded hole 2 on the slider 2 located on the bottom surface of the limit column 103 and pressed against the inner wall of the slide groove 3 of the lower cover plate 102. The four limit columns 103 are far away from each other to place larger explosives, and the four limit columns 103 are close to each other to place smaller explosives. Thus, by sliding to adjust the spacing between the four limit columns 103, explosives of different sizes can be placed. The slider 2 on the top surface of the limit column 103 The cross-section of the slider 2 on the top surface of the limiting column 103 and the bottom surface of the limiting column 103 are both T-shaped, which can prevent the slider 2 on the top surface of the limiting column 103 from detaching when sliding in the slide groove 3 of the upper cover plate 101, thereby improving the stability of the slider 2 on the top surface of the limiting column 103 in the slide groove 3 of the upper cover plate 101, and at the same time prevent the slider 2 on the bottom surface of the limiting column 103 from detaching when sliding in the slide groove 3 of the lower cover plate 102, thereby improving the stability of the slider 2 on the bottom surface of the limiting column 103 in the slide groove 3 of the lower cover plate 102.

[0025] like Figure 1 and Figure 2As shown, rubber pads 7 are bonded to the relatively close end surfaces of the upper cover plate 101 and the lower cover plate 102, and a through groove connected to the slide groove 3 is opened on the rubber pad 7. A scale line is set on the end surface of the rubber pad 7 along the length direction of the slide groove 3. When the limiting column 103 is slid, the slider 2 on the top surface of the limiting column 103 slides in the slide groove 3 of the upper cover plate 101, and the slider 2 on the bottom surface of the limiting column 103 slides in the slide groove 3 of the lower cover plate 102, and at the same time, both ends of the limiting column 103 move in the through groove. , and by observing the scale lines, the four limit columns 103 can be conveniently adjusted to slide at equal intervals. When the explosive is placed in the cartridge, the top surface of the explosive is pressed against the rubber pad 7 on the end surface of the upper cover plate 101 close to the lower cover plate 102, thereby increasing the friction between the top surface of the explosive and the rubber pad 7, and the bottom surface of the explosive is pressed against the rubber pad 7 on the end surface of the lower cover plate 102 close to the upper cover plate 101, thereby increasing the friction between the bottom surface of the explosive and the rubber pad 7, thereby improving the stability of the explosive placed in the cartridge.

[0026] The upper cover plate 101, the lower cover plate 102, the limit column 103 and the telescopic rod are all made of PP material. PP material is relatively cheap and has good impact resistance, which can save the manufacturing cost of the upper cover plate 101, the lower cover plate 102, the limit column 103 and the telescopic rod.

[0027] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
