Description

Technical Field

[0001] This utility model relates to the field of deep hole blasting technology, and more specifically, to a molybdenum mine blasting hole charging device that prevents clogging. Background Technology

[0002] Molybdenum mines are hard rock ore bodies, which are difficult to blast and require high precision in charging. When performing deep-hole blasting on molybdenum mines, it is necessary to pre-package the explosives inside the deep hole. Therefore, this type of charging device for deep-hole blasting technology in mining is required.

[0003] The existing charging devices all have fixed support structures. The ground needs to be leveled before use, otherwise the device cannot be kept in balance, which will affect the effect of use. At the same time, if there is water in the blast hole, the explosive will be affected by the mud and water and cannot reach the bottom of the hole quickly. The mud and water will also have a certain impact on the performance of the explosive.

[0004] A search revealed a Chinese patent with publication number CN221898361U that discloses a device for loading explosives through a blasting hole. This utility model uses a rotating shaft to drive the storage rod and support leg to change angles. By pressing the limiting block, the position of the support leg within the storage rod is adjusted, and the limiting block is fixed with the limiting hole, thereby fixing the support leg. The rotating shaft further strengthens the frame and improves stability. At the same time, the support block at the bottom of the support leg is made of rubber, making it suitable for humid areas with high water content.

[0005] However, in actual use, when the above-mentioned charging device is used to charge the explosives into the blast hole, there are certain stones inside the blast hole. These stones will gradually accumulate and pile up as the explosives enter, causing blockages to the advance of the explosives and affecting the efficiency of charging the explosives into the blast hole. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a molybdenum mine blasting hole charging device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A molybdenum mine blasting hole charging device with anti-clogging capability includes an outer tube, one end of which is fixedly connected to a baffle, and a base plate I fixedly connected to the bottom end of the outer tube. An inner tube is slidably connected to the inner side of the outer tube. Two limiting rods are fixedly connected to the bottom of the base plate I, and springs are fixedly connected to the inner sides of the limiting rods. A locking block is fixedly connected to one end of each spring, and the outer side of the locking block is slidably connected to the inner side of the limiting rod. A second base plate II is fixedly connected to the outer side of the inner tube, and two insertion holes are formed on the inner side of the second base plate. The inner side of each insertion hole is inserted into the outer side of the limiting rod. The outer tube and inner tube are each equipped with a protective mechanism at one end. The protective mechanism includes multiple positioning seats. One side of each positioning seat is fixedly connected to the outer side of the outer tube. A sliding groove is provided on the inner side of each positioning seat. A support is slidably connected to the inner side of the sliding groove. An arc-shaped baffle is fixedly connected to one side of the support. A buckle is fixedly connected to one end of the arc-shaped baffle. A pull rod is hinged to the inner side of the arc-shaped baffle. An inclined seat is fixedly connected to the bottom end of the pull rod. One side of the inclined seat is fixedly connected to the inner side of the inner tube. A splicing mechanism is provided at the bottom of the outer tube.

[0008] By adopting the above technical solution: the sliding of the inner tube inside the outer tube allows multiple arc-shaped baffles to be deflected. When entering the blast hole, the multiple arc-shaped baffles contract to form a cone shape, which can effectively prevent gravel from entering the outer tube and the inner tube. When loading explosives, the multiple arc-shaped baffles can expand to facilitate the explosives to pass through the inner tube and enter the blast hole, maintaining a smooth loading of explosives into the blast hole.

[0009] As a further description of the above technical solution: multiple outer rings are fixedly connected to the outer side of the outer tube, and multiple rollers are rotatably connected to the inner side of the outer rings.

[0010] By adopting the above technical solution, multiple outer rings and rollers are used to transform the sliding friction between the outer tube and the inner wall of the blast hole into rolling friction, so that the outer tube can smoothly enter the interior of the blast hole.

[0011] As a further description of the above technical solution: the splicing mechanism includes multiple slots, the slots are located on the inner side of the chassis, the inner side of the slots engages with a slider, the bottom of the slider is fixedly connected to a positioning frame, the inner side of the positioning frame is fixedly connected to a cylinder, and the top of the cylinder is fixedly connected to a pad.

[0012] By adopting the above technical solution, the splicing of the positioning frame and the outer tube makes it easier for staff to inspect and clean the inner wall of the inner tube through one end.

[0013] The technical effects and advantages of this utility model are as follows: 1. By setting up a protective mechanism, compared with the existing technology, the opening and closing of multiple arc-shaped baffles can effectively block the debris inside the blast hole from entering the interior of the outer tube. Combined with the rolling guidance of multiple rollers, the outer tube can smoothly enter the blast hole. At the same time, the explosive can smoothly and unimpededly enter the detonation point inside the blast hole, improving the loading efficiency of the explosive inside the blast hole. 2. By setting up a splicing mechanism, compared with the existing technology, the splicing and assembly of the positioning frame and the chassis can facilitate the transfer and use of the charging device. At the same time, the staff can directly visually inspect whether there is residual explosive on the inner wall of the inner tube, which simplifies the cleaning work and improves the efficiency of dealing with the blockage of the inner tube.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] The embodiments disclosed in this application are as follows: Figure 1-6 The anti-clogging molybdenum mine blasting hole charging device shown includes an outer tube 1, a baffle 2 fixedly connected to one end of the outer tube 1, a base plate 3 fixedly connected to the bottom end of the outer tube 1, an inner tube 4 slidably connected to the inner side of the outer tube 1, two limiting rods 23 fixedly connected to the bottom of the base plate 3, a spring 5 fixedly connected to the inner side of the limiting rod 23, a locking block 6 fixedly connected to one end of the spring 5, the outer side of the locking block 6 slidably connected to the inner side of the limiting rod 23, a second base plate 7 fixedly connected to the outer side of the inner tube 4, two insertion holes 8 opened on the inner side of the second base plate 7, the inner side of the insertion holes 8 being inserted into the outer side of the limiting rod 23, and a protective mechanism provided at one end of the outer tube 1 and the inner tube 4; the protective mechanism includes multiple positioning seats 11, one side of the positioning seat 11 fixedly connected to the outer side of the outer tube 1, and a sliding groove 12 opened on the inner side of the positioning seat 11, the inner side of the sliding groove 12 sliding... A support 13 is connected to the outer tube 1. An arc-shaped baffle 14 is fixedly connected to one side of the support 13. A buckle 17 is fixedly connected to one end of the arc-shaped baffle 14. A pull rod 15 is hinged to the inner side of the arc-shaped baffle 14. An inclined seat 16 is fixedly connected to the bottom end of the pull rod 15. One side of the inclined seat 16 is fixedly connected to the inner side of the inner tube 4. A splicing mechanism is provided at the bottom of the outer tube 1. The insertion hole 8 on the outer side of the chassis 2 7 is connected to the limiting rod 23. The positions of the insertion hole 8 and the chassis 1 3 are limited by the corresponding spring 5 and the locking block 6. This allows the inner tube 4 to push multiple inclined seats 16 and pull rod 15 to deflect and expand the arc-shaped baffle 14. Combined with the sliding guide of the support 13 and the corresponding positioning seat 11, multiple arc-shaped baffles 14 can be expanded to facilitate the explosive to enter the blast hole from one end of the inner tube 4.

[0023] Reference Figure 1 As shown, multiple outer rings 9 are fixedly connected to the outer side of the outer tube 1, and multiple rollers 10 are rotatably connected to the inner side of the outer rings 9. The multiple outer rings 9 and rollers 10 roll and guide the inner wall of the blast hole, thereby reducing the friction between the outer tube 1 and the inner wall of the blast hole and maintaining the stability of the outer tube 1 entering the blast hole.

[0024] Reference Figure 1 , Figure 3 and Figure 4 As shown, the splicing mechanism includes multiple slots 18, which are located inside the chassis 3. The slots 18 are engaged with sliders 19, and a positioning frame 20 is fixedly connected to the bottom of the slider 19. A cylinder 21 is fixedly connected to the inside of the positioning frame 20, and a pad 22 is fixedly connected to the top of the cylinder 21. The positioning frame 20 and the cylinder 21 can be separated from the outer tube 1, which facilitates the transfer and use of the loading device and allows the staff to observe and clean the inner wall of the inner tube 4 from one end.

[0025] The working principle of this utility model is as follows: When loading explosives into a molybdenum ore blasting hole, the outer tube 1 and the baffle 2 at one end are first inserted into the pre-drilled molybdenum ore blasting hole. The baffle 2 pushes the residual debris inside the blasting hole forward. At the same time, multiple outer rings 9 and rollers 10 on the outside of the outer tube 1 assist in rolling and guiding the outer tube 1 against the inner wall of the blasting hole. After the outer tube 1 and the baffle 2 have entered the appropriate position inside the blasting hole, the explosives are placed into the inner tube 4 from the other end. Then, multiple sliders 19 on one side of the positioning frame 20 are rotated and engaged with multiple slots 18 on one side of the chassis 3, so that the positioning frame 20 is connected to the outer tube 1. Then, the cylinder 21 is activated to push the pad 22 to push the inner tube 4, so that the explosives on the inner side of the inner tube 4 move along the inner tube 4 to the other end of the inner tube 4. Finally, the chassis is pushed. The second cylinder 7 drives the inner tube 4 to slide inside the outer tube 1, causing the two limiting rods 23 on one side of the chassis 3 to pass through the insertion hole 8. At the same time, the two springs 5 ​​push the locking block 6 to limit the chassis 7 that is locked outside the limiting rod 23. Meanwhile, the multiple inclined seats 16 at the other end of the inner tube 4 push the pull rod 15 to transmit power to the hinged arc-shaped baffle 14, causing the support 13 on one side of the arc-shaped baffle 14 to slide and deflect inside the corresponding positioning seat 11 and slide groove 12. After the multiple arc-shaped baffles 14 deflect and expand outward, the buckles 17 on one side of the multiple arc-shaped baffles 14 are positioned against the inner wall of the blast hole. Then, the cylinder 21 is activated again to push the pad 22 to push the explosive, so that the explosive enters the interior of the blast hole from the inner side of the outer tube 1, inner tube 4 and baffle 2. Finally, the outer tube 1 and inner tube 4 are removed from the interior of the blast hole for subsequent blasting operations.
