Description

Technical Field

[0001] This utility model relates to the field of mining technology, and in particular to a blast hole charging structure for mining blasting. Background Technology

[0002] A mine refers to an independent production and operation unit with a defined mining boundary for extracting ore. A mine mainly includes one or more mining workshops (also called pitheads, mine shafts, open-pit mines, etc.) and some auxiliary workshops. Most mines also include ore dressing plants. Mines include coal mines, metallic mines, non-metallic mines, building material mines, and chemical mines, etc. Mine scale is usually expressed in terms of annual or daily output. Annual output is the amount of ore produced by the mine each year. Some mines require blasting with explosives during the mining process to facilitate ore extraction. Chinese patent application number 201921679041.2 describes a mining blasting method. The beneficial effects of the borehole charging structure are as follows: the charging cylinder is placed at the upper end of the through hole by the slider a moving in the groove a, and then the charging cylinder is pressed down to align with the through hole. Then the explosive is loaded into the charging cylinder through the feed pipe. Furthermore, the piston is driven by pushing the push rod downward to fully load the explosive into the borehole, resulting in a higher density of explosive loading and further improving the blasting effect. However, when using it, after the explosive is squeezed, the entire device needs to be placed at the borehole. During use, multiple mechanisms are required to squeeze the explosive one by one, resulting in a certain degree of resource waste. Utility Model Content

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example 1

[0028] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention. This embodiment provides a blast hole charging structure for mining blasting. The blast hole charging structure for mining blasting includes a support assembly 100 and a charging assembly 200. By setting up the support assembly 100, it is convenient for workers to place the device and operate each component, thereby compacting the explosive inside the blast hole. By setting up the charging assembly 200, it is convenient for workers to quickly seal the blast hole and improve the density of the explosive.

[0029] The support assembly 100 includes a base plate 101 and a fixing frame 102, the fixing frame 102 being fixedly connected to the top of the base plate 101.

[0030] The base plate 101 facilitates the placement of the device by the staff, while the fixing frame 102 enables quick operation of each component, improving work efficiency.

[0031] The drug loading assembly 200 includes a drug inlet pipe 201 and a plugging pipe 202. The drug inlet pipe 201 is disposed inside the base plate 101, and the plugging pipe 202 is disposed at the bottom of the base plate 101.

[0032] By setting up the inlet pipe 201, it is convenient for the staff to fill the blast hole with explosives. At the same time, the plugging pipe 202 can seal the blast hole after compaction. Example 2

[0033] Reference Figure 2 and Figure 3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0034] Specifically, the base plate 101 includes a sliding groove 101a and a fixing rod 101b. The sliding groove 101a is formed inside the base plate 101, and the fixing rod 101b is slidably connected inside the base plate 101.

[0035] By setting the slide groove 101a, the drug inlet tube 201 can drive the fixed rod 101b to slide inside the slide groove 101a. At the same time, under the action of the fixed rod 101b, the movement of the drug inlet tube 201 can remain stable.

[0036] Specifically, the base plate 101 also includes a first spring 101c and a through hole 101d. The first spring 101c is sleeved on the outside of the fixing rod 101b, and the through hole 101d is opened inside the base plate 101. One end of the first spring 101c is welded to one side of the inner wall of the slide groove 101a.

[0037] The operator pushes the feed tube 201, causing it to slide inside the slide groove 101a. Simultaneously, the movement of the feed tube 201 causes the fixing rod 101b on its outer side to slide inside the base plate 101. The fixing rod 101b and the base plate 101 are in a sliding connection relationship, which in turn compresses the first spring 101c, exposing the through hole 101d. The operator can then observe the explosive charge inside the borehole through the through hole 101d.

[0038] Specifically, the fixed frame 102 includes an extrusion rod 102a, a rotating tube 102b, and an extrusion head 102c. The extrusion rod 102a is disposed inside the fixed frame 102. The rotating tube 102b is rotatably connected to the bottom of the fixed frame 102. The inner wall of the rotating tube 102b is threadedly engaged with the outer side of the extrusion rod 102a. The extrusion head 102c is fixedly connected to the bottom of the extrusion rod 102a.

[0039] Rotating the rotating tube 102b causes the extrusion rod 102a to move. When the extrusion rod 102a moves, it causes the extrusion head 102c to move inside the inlet tube 201 and the plugging tube 202, thereby compressing the explosive inside the borehole and increasing the density of the explosive. Example 3

[0040] Reference Figure 4 and Figure 5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0041] Specifically, the drug inlet tube 201 includes a fixing ring 201a and a drug inlet cover 201b. The fixing ring 201a is fixedly connected to the outside of the drug inlet tube 201, and the outside of the fixing ring 201a is fixedly connected to one end of the fixing rod 101b. The drug inlet cover 201b is fixedly connected to the inner wall of the drug inlet tube 201.

[0042] The extrusion rod 102a is not connected to the fixing frame 102. The size of the internal slot of the fixing frame 102 is larger than the size of the extrusion rod 102a. In the equivalent of embodiment 2, when the rotating tube 102b is rotated in the opposite direction, the extrusion rod 102a can drive the extrusion head 102c to move, so that the extrusion head 102c is disengaged from the inside of the inlet tube 201 and the inlet cover 201b. After the extrusion head 102c moves to the designated position, the operator can fill the explosive inside the borehole through the inlet cover 201b. At the same time, after the explosive inside the borehole is compacted, the inlet tube 201 is pushed, and the fixing rod 101b can be moved through the fixing ring 201a, so that the through hole 101d can be exposed.

[0043] Specifically, the blocking tube 202 includes a fixing plate 202a, an adjusting member 202b, and a positioning member 202c. The fixing plate 202a is fixedly connected to the bottom of the base plate 101, the adjusting member 202b is disposed at the bottom of the fixing plate 202a, and the positioning member 202c is disposed at the bottom of the base plate 101.

[0044] Under the action of the adjusting member 202b, the position of the other clamping plate 202c-5 located at one end of the moving rod 202b-4 can be adjusted, thereby allowing the other clamping plate 202c-5 to disengage from the inside of the blocking tube 202, while facilitating the clamping of the blocking tube 202.

[0045] Specifically, the plugging tube 202 also includes a side block 202d, a sealing plug 202e, and a positioning plug 202f. The side block 202d is fixedly connected to the outside of the plugging tube 202, the sealing plug 202e is threadedly connected to the inside of the plugging tube 202, and the positioning plug 202f is located inside the side block 202d.

[0046] After the plugging tube 202 is disassembled, the positioning bolt 202f is rotated to move to the designated position, thereby fixing the plugging tube 202 and preventing it from falling out of the borehole. Then, the sealing plug 202e is rotated to seal the plugging tube 202, thereby sealing the borehole.

[0047] The adjusting component 202b includes a first sliding plate 202b-1, a screw hole 202b-2, an adjusting tube 202b-3, and a moving rod 202b-4. The first sliding plate 202b-1 is slidably connected to the inside of the fixed plate 202a. The screw hole 202b-2 is opened inside the first sliding plate 202b-1. The adjusting tube 202b-3 is rotatably connected to the rear surface of the first sliding plate 202b-1. The moving rod 202b-4 is threadedly connected to the inside of the adjusting tube 202b-3.

[0048] Rotating the adjusting tube 202b-3 can move the moving rod 202b-4. At the same time, by adjusting the position of the first sliding plate 202b-1, the position of the other clamping plate 202c-5 at the moving rod 202b-4 can be adjusted, which makes it easier for the staff to disassemble and assemble the blockage tube 202.

[0049] The positioning component 202c includes a second sliding plate 202c-1, a fixing tube 202c-2, and a second spring 202c-3. The second sliding plate 202c-1 is disposed at the bottom of the base plate 101, the fixing tube 202c-2 is fixedly connected to the front surface of the second sliding plate 202c-1, and the second spring 202c-3 is welded to one side of the inner wall of the fixing tube 202c-2.

[0050] When positioning the plug tube 202, the plug tube 202 is placed in the inner ring of the clamping plate 202c-5. At the same time, the position of the moving rod 202b-4 is adjusted by adjusting the adjusting tube 202b-3, which causes the plug tube 202 to be squeezed. Under the elastic force of the second spring 202c-3, the plug tube 202 is clamped and positioned.

[0051] The positioning component 202c also includes a sliding rod 202c-4 and a locking plate 202c-5. The sliding rod 202c-4 is slidably connected to the inside of the fixed tube 202c-2, and the locking plate 202c-5 is fixedly connected to one end of the sliding rod 202c-4.

[0052] Under the action of the clamping plate 202c-5, its inner ring can fit against the outer side of the plugging tube 202. Then, under the action of the other clamping plate 202c-5 at the moving rod 202b-4, the other clamping plate 202c-5 at the moving rod 202b-4 is fixedly connected to the end of the moving rod 202b-4 away from the adjusting tube 202b-3. Then, under the action of the two clamping plates 202c-5, the plugging tube 202 can be clamped and positioned, and at the same time, it is convenient to disassemble and assemble the plugging tube 202, so that the plugging tube 202 can plug the blast hole.

[0053] In use, the operator first moves the device to the designated position according to the location of the blast hole. Then, they rotate the bolts inside the fixed plate 202a and the bolts inside the other fixed plate 202a at the location of the second sliding plate 202c-1, allowing the first sliding plate 202b-1 and the second sliding plate 202c-1 to slide. Next, the operator rotates the sealing plug 202e, disengaging it from the plugging tube 202. Then, they push the first sliding plate 202b-1 and the second sliding plate 202c-1, causing the plugging tube 202 to... Move to the initial position, insert the plugging tube 202 into the borehole, and then stabilize the base plate 101. Rotate the rotating tube 102b, which allows the extrusion rod 102a to move. When the extrusion rod 102a reaches the designated position, the extrusion head 102c disengages from the inlet tube 201, simultaneously exposing the inlet cover 201b. The operator then places the explosive through the inlet cover 201b, allowing the explosive to pass through the inlet tube 201 and the plugging tube 202 into the borehole. Inside the borehole, after the explosive reaches the designated weight, the operator rotates the rotating tube 102b again. This causes the rotating tube 102b to move the compression rod 102a, allowing the compression head 102c to enter the borehole through the blocking tube 202. This compresses the explosive inside the borehole, increasing its density. After the explosive is compressed, the operator rotates the rotating tube 102b again, causing the compression head 102c to disengage from the feed hood 201b. The condition of the explosive inside the borehole is then observed through the through hole 101d. Then, rotate the adjusting tube 202b-3 again to move the moving rod 202b-4, thereby causing the other clamping plate 202c-5 at the moving rod 202b-4 to disengage from the outside of the blocking tube 202. At the same time, push the clamping plate 202c-5 to compress the second spring 202c-3. Then, the operator rotates the sealing plug 202e to allow the sealing plug 202e to enter the interior of the blocking tube 202, thereby preventing external debris from entering the interior of the blocking tube 202. Then, the blocking tube 202 is fixed and positioned by the positioning bolt 202f.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
