Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1 As shown:

[0027] An adjustable-distance borehole interval charging device includes a propellant tube 101 and a placement port 102 formed on the surface of the propellant tube 101 for placing explosives.

[0028] In this implementation plan: In order to solve the technical problems existing in the prior art, such as the "when preparing for blasting, multiple explosives may need to be placed in a single blast hole. However, it is difficult to accurately control the interval between the explosives during the placement process, and it is inconvenient to determine the placement position of multiple sets of explosives, so that the explosives are difficult to produce the expected effect and affect the blasting effect" in combination, this problem is obviously a real and difficult problem to solve. All electrical equipment involved in this product is powered by an external power source.

[0029] Furthermore:

[0030] like Figures 1-3 As shown:

[0031] Based on the above: one end of the propellant tube 101 is fixed with a sleeve 104;

[0032] The sleeve 104 has a sliding limit rod 105 inside, and the surface of the push rod 105 is provided with scale lines 106. The inner side wall of the sleeve 104 is fixed with a limit strip, and the surface of the push rod 105 is provided with a sliding groove that matches the limit strip. The push rod 105 and the limit strip are slidably connected through this sliding groove. The outer surface of the propellant tube 101 is fixed with a retaining ring 103.

[0033] A drive mechanism 2 is installed on the sleeve 104 to move the drive rod 105;

[0034] The drive mechanism 2 includes fixed plates 201 symmetrically arranged on the surface of the sleeve 104, a reciprocating screw 203 rotatably connected between the two sets of fixed plates 201 via bearings, and a drive motor 202 fixed on the surface of one set of fixed plates 201 to drive the reciprocating screw 203 to rotate.

[0035] The reciprocating screw 203 is threaded with an L-shaped bracket 205. A locking pin 207 slides on one end of the L-shaped bracket 205. A spring 206 is wound around the surface of the locking pin 207. The two ends of the spring 206 are fixedly connected to the locking pin 207 and the L-shaped bracket 205 respectively. The surface of the push rod 105 is provided with multiple sets of equally spaced insertion holes 208. The locking pin 207 is inserted into one of the insertion holes 208. A rectangular hole is provided on the upper surface of the sleeve 104.

[0036] The output end of the drive motor 202 is fixed to one end of the reciprocating lead screw 203. One end of the L-shaped frame 205 is provided with a moving hole that matches the locking pin 207. The locking pin 207 and the L-shaped frame 205 are slidably connected through this moving hole.

[0037] A limiting rod 204 is fixed between two sets of fixing plates 201, and the L-shaped frame 205 slides on the surface of the limiting rod 204 through the through hole.

[0038] The top rod 105 is equipped with an interconnectable splicing mechanism 3;

[0039] The splicing mechanism 3 includes an insert block 301 fixed to one end of the top rod 105, a locking block 303 sliding inside the insert block 301, and a spring 302 fixed between the insert block 301 and the locking block 303.

[0040] The other end of the push rod 105 is provided with a slot 304 that is compatible with the insert block 301, and the push rod 105 is provided with a lock hole 305 that is compatible with the lock block 303 at the position of the slot 304.

[0041] A limiting groove adapted to the locking block 303 is provided on one side of the insert block 301, and the locking block 303 and the insert block 301 are slidably connected through this limiting groove.

[0042] In this implementation scheme: When using the adjustable-distance borehole interval charging device, the explosive is first placed into the explosive tube 101 through the placement port 102. At this time, one end of the explosive tube 101 is inserted into the drilled hole, and the retaining ring 103 is fixed and pressed against the rock sidewall. Then, the drive motor 202 is connected to the battery for power. Starting the drive motor 202 drives the reciprocating screw 203 to rotate. Due to the threads of the reciprocating screw 203 and the L-shaped bracket 205... The connection drives the L-shaped frame 205 to move, and the L-shaped frame 205 moves on the limiting rod 204. The limiting rod 204 limits the L-shaped frame 205, making the movement of the L-shaped frame 205 more stable. Since the locking pin 207 is inserted into the insertion hole 208, the spring 206 can push the locking pin 207 into the insertion hole 208 steadily. The movement of the L-shaped frame 205 drives the top rod 105 to move.

[0043] By moving the push rod 105, the explosive inside the blasting tube 101 can be moved and pushed into the rock hole. In this process, by observing the scale line 106, it can be determined that the push rod 105 has extended into the rock hole, and then the filled explosive is tamped.

[0044] At this point, observe the position of the scale line 106 on the top rod 105. Then, fill the obstruction with material. As the drive motor 202 drives the reciprocating screw 203 to rotate, the reciprocating screw 203 drives the L-shaped frame 205 to move reciprocally. When the L-shaped frame 205 drives the top rod 105 to move unidirectionally, after the L-shaped frame 205 moves to the right end of the sleeve 104, this process will drive the top rod 105 to move synchronously to the right. Then, by pulling the locking pin 207, the locking pin 207... 07 disengages from the socket 208. When the drive motor 202 drives the reciprocating screw 203 to move the L-shaped frame 205 to move the left end of the sleeve 104 again, the locking pin 207 aligns with the socket 208 of the push rod 105. Subsequently, the locking pin 207 is inserted into the socket 208. When the drive motor 202 moves the L-shaped frame 205 to the right, it further moves the push rod 105 to the right. Through this operation, the push rod 105 can be pushed or pulled out in one direction.

[0045] The barrier is then placed inside the explosive tube 101, and pushed into the rock hole again by the push rod 105. The barrier is then tamped down, and this operation is repeated to ensure that the explosive separation effect is fully utilized. After each tamping, the scale line 106 on the push rod 105 is observed to record the tamping of the barrier and the explosive. By continuously observing the scale line 106 on the push rod 105, the spacing between the explosives can be accurately controlled. By flexibly filling the barrier, the precision of the explosive spacing can be accurately controlled, and the placement of the explosive can be determined so that the explosive detonation can produce the expected effect, thereby achieving a better blasting effect.

[0046] When the push rod 105 is continuously fed, if its length is insufficient to push the explosive to the specified distance, the push rod 105 can be spliced. First, press the locking block 303 on one set of push rods 105, compressing the locking block 303 into the insert block 301 and compressing the second spring 302. Then, pick up another set of push rods 105, aligning the slot 304 on the other set of push rods 105 with the insert block 301, and insert the slot 304 on the other set of push rods 105 into the insert block 301. At this time, when the locking block 303 aligns with the locking hole 305, the second spring 302 rebounds and drives the locking block 303 into the locking hole 305, connecting and locking the two sets of push rods 105, thus realizing the splicing operation. By continuously splicing, push rods 105 of different lengths can be used to push explosives or obstruction groups to deeper positions in the rock eyeholes, improving the effectiveness of the device.

[0047] It should be noted that: the inner wall of the sleeve 104 is fixed with a limiting strip, and the surface of the push rod 105 is provided with a sliding groove that matches the limiting strip. The push rod 105 and the limiting strip are slidably connected through this sliding groove. The outer surface of the propellant tube 101 is fixed with a fixing retaining ring 103. Through the cooperation of the sliding groove and the limiting strip, the push rod 105 can be limited, making the push rod 105 more stable during its movement on the sleeve 104.

[0048] It should be noted that this device is also equipped with a storage battery, which can supply power to the drive motor 202.

[0049] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
