[0002] In open-pit deep-hole blasting operations, if the amount of mixed explosive injected into the hole exceeds the designed amount, the traditional treatment method often requires abandoning the blast hole and using a powered rotary drill to re-drill near the blast hole; this approach not only incurs high costs (including the cost of using the drill and explosive waste), but also poses safety hazards when powered equipment enters the blast area, which is not conducive to the safe conduct of blasting operations. Summary of the Invention

[0003] In order to overcome the shortcomings that in traditional deep-hole blasting operations, the treatment method for excessive explosives requires abandoning the blast hole and using a powered rotary drill to re-drill near the blast hole, which is costly and poses safety hazards when powered equipment enters the blast area and is not conducive to the safe conduct of blasting operations, the present invention provides a deep-hole mixed explosive extraction device at a blasting site.

[0004] Technical Solution: A deep-hole mixed explosive extraction device at a blasting site includes a chassis; it also includes a manual hoist, a steel wire rope, a round tube, and a baffle; the manual hoist is fixedly connected to the chassis; two steel wire ropes are arranged on the manual hoist; the two steel wire ropes are commonly fixedly connected to the round tube; the baffle is rotatably connected inside the round tube; a groove for avoiding detonator leads is opened on the baffle.

[0007] Optionally, the chassis bracket is made by die-casting with high-strength aluminum alloy material.

[0008] Optionally, the baffle is made of rubber material.

[0009] Optionally, it also includes a fixing frame, a placing frame, and a counterweight; the fixing frame is connected to the chassis; two placing frames are fixedly connected to the fixing frame; the counterweight is placed between the two placing frames.

[0010] Optionally, a wire groove is opened in the middle of the fixing frame, and the middle part at the rear of the fixing frame is directly above the quarter point on the inner wall at the rear of the round tube.

[0011] Optionally, the fixing frame further includes a slide rail, a second mounting frame, a rotating ring, a limiting plate, a grip rod, a plug rod, and a brush plate; the second mounting frame is fixedly connected to the bottom frame; two slide rails are fixedly connected to the bottom frame; the fixing frame slides within the two slide rails; the rotating ring is rotatably connected to the second mounting frame; two limiting plates are fixedly connected to the rotating ring; a through hole is respectively formed in each of the two limiting plates, and two steel wire ropes respectively penetrate through one through hole; a plurality of plug rods are fixedly connected to the rotating ring; a plurality of plug rods are inserted into the round tube; a brush plate is fixedly connected to each plug rod, and a plurality of bristles are respectively arranged on each brush plate.

[0012] Optionally, the wall of the through hole on the limiting plate is smooth.

[0013] Optionally, the lower part of the plug rod is conical.

[0014] The beneficial effects of the present invention are as follows: 1. The present invention takes out the excess explosive by controlling the lowering and rising of the round tube and the baffle, avoiding the problem that when the amount of explosive injected into the hole exceeds the designed amount in the case of mixed loading of explosives, the blast hole needs to be discarded, resulting in waste of mixed loading explosives and potential safety hazards; and by making the detonator lead wire located in the groove, when the baffle rotates to close the round tube, the detonator lead wire located in the groove is pushed towards the inner wall of the round tube, and the detonator lead wire is located in the movable space formed by the groove and the inner wall of the round tube, avoiding wear and tear and damage to the detonator lead wire.

[0015] 2. The present invention fixes the detonator lead wire on the counterweight block by using tape, and then removes the counterweight block from the two placement frames. Under the action of the counterweight block, the detonator lead wire is straightened. After the detonator lead wire is straightened, in the front-rear direction, the detonator lead wire is aligned with the groove on the baffle. In this way, when the baffle rotates to push the detonator lead wire towards the inner wall of the round tube, it is ensured that the detonator lead wire is located in the movable space formed by the groove and the inner wall of the round tube, avoiding damage to the detonator lead wire.

[0016] 3. The present invention makes the detonator lead wire close to the inner wall of the round tube through the fixing frame, avoiding a large interaction force between the detonator lead wire and the groove of the baffle, and reducing the problem of wear of the detonator lead wire when the round tube and the baffle rise.

Detailed implementation manners

[0019] The following describes the implementation manners of the present invention with reference to the attached drawings.

[0020] Embodiment 1 A deep-hole bulk-loading explosive extraction device at the blasting site, as Figures 1 - 6 shown, includes a chassis 1; It further includes a manual hoist 2, a steel wire rope 3, a round tube 4 and a baffle plate 5; the manual hoist 2 is fixedly connected to the chassis 1; two steel wire ropes 3 are arranged on the manual hoist 2; the two steel wire ropes 3 are commonly fixedly connected to the round tube 4; the lower part inside the round tube 4 is rotatably connected to the baffle plate 5; a groove 501 is opened on the baffle plate 5.

[0021] In order to facilitate the insertion of the round tube 4 into the explosive, the bottom of the round tube 4 is an obliquely cut ellipse.

[0022] In order to facilitate the insertion of the baffle plate 5 into the explosive, the end of the baffle plate 5 away from the groove 501 is set to be pointed.

[0023] The support of the chassis 1 is made by die-casting with high-strength aluminum alloy material, having sufficient stability and load-bearing capacity.

[0024] The baffle plate 5 is made of rubber material, having good sealing performance.

[0025] It also includes a fixing frame 22, a placing frame 23 and a counterweight 24; the fixing frame 22 is connected to the bottom frame 1; two placing frames 23 are fixedly connected to the fixing frame 22; the counterweight 24 is placed between the two placing frames 23.

[0026] In order to make the detonator lead 8 located at the rear quarter point of the inner wall of the round tube 4, a wire groove 2201 is opened in the middle of the fixing frame 22, and the middle part at the rear of the fixing frame 22 is directly above the rear quarter point of the inner wall of the round tube 4.

[0027] Taking Figure 1 the perspective as a reference, the side where the bottom frame 1 is labeled is the front side, and the side where the manual hoist 2 is labeled is the rear side.

[0028] During use, manually carry the device above the blast hole with excessive mixed explosive injection. The round tube 4 is directly above the blast hole. Then, manually pass the detonator lead 8 in the blast hole through the round tube 4 and make the detonator lead 8 located in the groove 501 of the baffle 5. Then, manually drive the manual hoist 2 manually, so that the two steel wire ropes 3 are relaxed. Under the action of the self - gravity of the round tube 4, the round tube 4 descends into the blast hole. In order to facilitate the insertion of the round tube 4 into the explosive, the bottom of the round tube 4 is set as an obliquely cut ellipse. Due to the resistance of the explosive, when the baffle 5 descends, it rotates to a vertical state with the groove 501 facing upwards; compared with lifting the round tube 4 by using a single steel wire rope 3, lifting the round tube 4 by two steel wire ropes 3 together can reduce the sway of the round tube 4 and ensure that the round tube 4 is inserted into the explosive in a vertical state; then, manually drive the manual hoist 2 manually to wind up the two steel wire ropes 3. The two steel wire ropes 3 drive the round tube 4 to rise. When rising, due to the resistance of the explosive and the self - gravity of the baffle 5, the baffle 5 rotates downward to seal the lower part of the round tube 4. In this way, the round tube 4 and the baffle 5 rise to take out the excess explosive. After taking out, manually turn the round tube 4 over and pour the explosive into the recovery container. Repeat the above process until all the excess explosive in the blast hole is taken out; in this way, it is avoided that when the amount of mixed explosive injected into the hole exceeds the designed amount, the blast hole needs to be abandoned, resulting in waste of mixed explosive and potential safety hazards; note that when the baffle 5 rotates, the detonator lead 8 located in the groove 501 is pushed towards the inner wall of the round tube 4. The detonator lead 8 is located in the movable space formed by the groove 501 and the inner wall of the round tube 4. When the round tube 4 and the baffle 5 rise, the detonator lead 8 is always in this movable space, avoiding abrasion, pulling and damage to the detonator lead 8.

[0029] It should be noted that the rotation angle of the baffle 5 is limited, that is, when the baffle 5 is in a horizontal state to seal the lower part of the round tube 4, the baffle 5 cannot continue to rotate clockwise downward, and when the baffle 5 is in a vertical state to open the lower part of the round tube 4, the baffle 5 cannot continue to rotate counterclockwise upward.

[0030] When actually arranging detonators, the detonator lead 8 is inclined in the explosive. The inclination angle is limited by the uncertainty of manual arrangement. There is a situation where the detonator lead 8 is not directly opposite to the groove 501 on the baffle 5 in the front-back direction. Moreover, when filling the explosive, the explosive will pull the detonator lead 8, resulting in the detonator lead 8 being in a bent and loose state in the explosive. Similarly, there is a situation where the detonator lead 8 is not directly opposite to the groove 501 on the baffle 5 in the front-back direction. After the baffle 5 descends and rotates, the detonator lead 8 is not in the moving space formed by the groove 501 and the inner wall of the circular tube 4, but is pressed against the inner wall of the circular tube 4 by other parts of the baffle 5. When the circular tube 4 and the baffle 5 rise later, the circular tube 4 and the baffle 5 will wear and pull the detonator lead 8, thus causing damage to the detonator lead 8. Therefore, after manually passing the detonator lead 8 in the blast hole through the circular tube 4 and making the detonator lead 8 located in the groove 501 of the baffle 5, as Figure 4 and Figure 5 shown, the detonator lead 8 is fixed to the counterweight 24 with tape. Then, the counterweight 24 is removed from the two placement racks 23. Under the action of the counterweight 24, the detonator lead 8 is straightened. After the detonator lead 8 is straightened, in the front-back direction, the detonator lead 8 is directly opposite to the groove 501 on the baffle 5. In this way, when the baffle 5 rotates and pushes the detonator lead 8 towards the inner wall of the circular tube 4, it is ensured that the detonator lead 8 is in the moving space formed by the groove 501 and the inner wall of the circular tube 4, avoiding damage to the detonator lead 8.

[0031] Considering that although the detonator lead 8 is directly opposite to the groove 501 on the baffle 5 in the front-back direction, when the baffle 5 rotates and pushes the detonator lead 8 towards the inner wall of the circular tube 4, the detonator lead 8 is in close contact with the groove 501 of the baffle 5, and there is an interaction force between the detonator lead 8 and the groove 501 of the baffle 5. When the circular tube 4 and the baffle 5 rise, the baffle 5 will wear and pull and damage the detonator lead 8. Therefore, after fixing the detonator lead 8 to the counterweight 24 with tape, the position of the detonator lead 8 is adjusted so that the detonator lead 8 is located on the wire groove 2201. The wire groove 2201 is located in the middle of the fixing frame 22, and the middle part at the rear of the fixing frame 22 is directly above the rear quarter point of the inner wall of the circular tube 4. While ensuring that the detonator lead 8 is directly opposite to the groove 501 on the baffle 5 in the front-back direction, the detonator lead 8 is made close to the inner wall of the circular tube 4. In this way, after the baffle 5 rotates, it is avoided that there is a large interaction force between the detonator lead 8 and the groove 501 of the baffle 5, reducing the problem of wear of the detonator lead 8 when the circular tube 4 and the baffle 5 rise.

[0032] Embodiment 2 On the basis of Embodiment 1, as Figures 4 - 8As shown in the figure, it further includes a slide rail 21, a second mounting bracket 31, a rotating ring 32, a limiting plate 33, a grip rod 34, a plug rod 35 and a brush plate 36; the second mounting bracket 31 is welded on the chassis 1; two slide rails 21 are fixedly connected to the chassis 1; the fixed bracket 22 slides in the two slide rails 21; the second mounting bracket 31 is rotatably connected with the rotating ring 32; two limiting plates 33 are welded on the rotating ring 32; a through hole is respectively opened on each of the two limiting plates 33, and the three steel wires 3 respectively penetrate through a through hole; four plug rods 35 are welded on the rotating ring 32; two plug rods 35 are inserted into the round tube 4; a brush plate 36 is welded on each plug rod 35, and a number of bristles are respectively arranged on each brush plate 36.

[0033] In order to reduce the wear of the steel wire 3, the wall of the through hole on the limiting plate 33 is smooth.

[0034] In order to facilitate the insertion of the plug rod 35 into the round tube 4, the lower part of the plug rod 35 is conical.

[0035] In order to smoothly insert the round tube 4 into the explosive, the diameter of the round tube 4 needs to be set smaller than the inner diameter of the blast hole. This results in some explosive remaining on the inner wall of the blast hole after the round tube 4 removes the excess explosive, causing waste. Moreover, each time the round tube 4 removes the excess explosive, the explosive between the outer wall of the round tube 4 and the inner wall of the blast hole will fall downward. When the round tube 4 performs the last material extraction, the explosive between the outer wall of the round tube 4 and the inner wall of the blast hole will fill the originally appropriate amount of explosive. Combined with the remaining explosive on the inner wall of the blast hole, it will cause the amount of explosive in the blast hole to still be excessive, leading to excessive explosion during detonation. Therefore, after the round tube 4 removes the excess explosive in the blast hole, manually pull the fixed frame 22 to slide forward in the two slide rails 21, so that the fixed frame 22 and the detonator lead 8 are away from the steel wire rope 3, giving the steel wire rope 3 sufficient space for movement. Then, manually insert the insertion rod 35 and the brush plate 36 into the round tube 4. Next, manually drive the manual hoist 2 to relax the two steel wire ropes 3. Under the action of the self-gravity of the round tube 4, the round tube 4 descends into the blast hole, and the insertion rod 35 and the brush plate 36 follow the round tube 4 and descend into the blast hole. The bristles of the brush plate 36 come into contact with the inner wall of the blast hole. Then, control the operator to rotate the rotating ring 32 through the grip rod 34. The rotating ring 32 drives the two limit plates 33 to rotate. When the two limit plates 33 rotate, they drive the two steel wire ropes 3 and the round tube 4 to rotate. The insertion rod 35 and the brush plate 36 follow the round tube 4 to rotate and sweep the remaining explosive on the inner wall of the blast hole. Since the two steel wire ropes 3 will be wound around each other and store energy when rotating, when the operator releases the grip rod 34, the two steel wire ropes 3 and the round tube 4 rotate in reverse to restore their original positions. During the restoration rotation, the round tube 4 rotates faster, and the insertion rod 35 and the brush plate 36 again follow the round tube 4 to rotate quickly to completely sweep the remaining explosive on the inner wall of the blast hole. Then, repeat the operations of the round tube 4 descending and the rotating ring 32 rotating until the remaining explosive on the inner wall of the blast hole is completely swept clean. Then, manually remove the insertion rod 35 and the brush plate 36 from the round tube 4, manually push the fixed frame 22 to slide backward in the two slide rails 21 to reset, and then control the round tube 4 to descend again to remove the swept explosive and the explosive that has fallen downward between the outer wall of the round tube 4 and the inner wall of the blast hole, avoiding waste of explosive and excessive amount of explosive. It should be noted that in blasting operations, since the depth and diameter of the blast hole are known, and the depth of the appropriate amount of explosive filled in the blast hole can also be calculated. That is, the maximum depth that the round tube 4 needs to descend is the depth of the blast hole minus the depth of the appropriate amount of explosive filled, which can ensure that the swept explosive and the explosive that has fallen downward between the outer wall of the round tube 4 and the inner wall of the blast hole are basically completely removed.

[0036] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention.
