[0023] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] The present invention provides a charging device for a directional shaped energy blasting tube. Figure 1-5 As shown, the charging device for directional shaped charge blasting tubes includes: a workbench 1 and a plate chain conveyor 3 installed on the workbench 1 for conveying blasting tubes 8; a motor reducer 4 installed on one side of the workbench 1, and the output shaft of the motor reducer 4 is connected to the output rod of the plate chain conveyor 3; a charging machine 6 provided above the workbench 1 for conveying explosives to the blasting tube 8; a drug delivery pipe 7 fixedly installed on the blasting tube 8 for discharging explosives into the blasting tube 8; and a limiting mechanism provided on the workbench 1 for limiting the blasting tube 8 on the plate chain conveyor 3.

[0025] In this embodiment, the blasting tube 8 is placed on the support plate 12, and then the motor reducer 4 is started, and the plate chain conveyor 3 begins to convey the blasting tube 8 to the charging position, and then the valve on the drug delivery pipe 7 is started to discharge the explosives into the blasting tube 8 through the drug delivery pipe 7. By controlling the frequency of the plate chain conveyor 3 and the discharge speed of the loader 6, automatic charging operation is realized. The limiting mechanism ensures the stability of the blasting tube 8 during the transportation and charging process. After the loading is completed, the blasting tube 8 continues to be conveyed to the next process by the plate chain conveyor 3. Compared with the traditional manual charging method, the present device realizes automatic charging, greatly improves production efficiency, and also improves work safety. The blasting tube 8 is limited on the plate chain conveyor 3 by the limiting mechanism to ensure that the blasting tube 8 maintains a stable position and posture during the transportation and charging process to prevent it from moving or tilting and affecting the charging effect.

[0026] In a further preferred embodiment of the present invention, a support frame 5 is fixedly installed on the top of the workbench 1, and the support frame 5 is fixedly connected to the charging machine 6. A hydraulic cylinder 9 is fixedly installed on the top of the support frame 5, and a push plate 10 is fixedly installed on the output rod of the hydraulic cylinder 9, and the push plate 10 is in sliding contact with the inner wall of the charging machine 6.

[0027] In this embodiment, when the hydraulic cylinder 9 is extended and retracted, the push plate 10 will slide on the inner wall of the charging machine 6, thereby pushing the explosives into the drug delivery tube 7 along a specific path and finally discharged into the blasting tube 8. This design can ensure the uniform distribution and precise control of the explosives. Through the coordinated use of the hydraulic cylinder 9 and the push plate 10, the precise control and uniform distribution of the explosives can be achieved, thereby improving the charging accuracy and ensuring the blasting effect. The addition of the support frame 5 enhances the stability of the charging machine 6 during operation and avoids problems such as inaccurate charging or malfunction due to vibration or shaking.

[0028] In a further preferred embodiment of the present invention, a connecting plate is fixedly installed on the bracket 2 of the plate chain conveyor 3, and a discharge hopper 11 is fixedly installed on the top of the connecting plate. The hopper mouth of the discharge hopper 11 is located above the blasting tube 8, and the mouth of the drug delivery tube 7 is located directly above the discharge hopper 11.

[0029] In this embodiment, after the explosives are discharged from the charging machine 6 through the drug delivery pipe 7, they will directly fall into the discharge hopper 11 and then flow into the blasting tube 8 along the hopper mouth. This design ensures the accurate delivery and efficient utilization of the explosives. By adding the discharge hopper 11, the explosives can be more effectively received and guided into the blasting tube 8, reducing the waste and loss of explosives during the transportation process and improving the charging efficiency. The design of the discharge hopper 11 enables the explosives to flow more smoothly into the blasting tube 8, avoiding charging problems caused by uneven distribution or blockage of explosives, and optimizing the charging process.

[0030] In a further preferred embodiment of the present invention, the limiting mechanism includes: a support plate 12 installed on the plate chain of the plate chain conveyor 3; a placement opening opened at the top of the support plate 12, and the placement opening is adapted to the blasting tube 8; anti-slip pads 13 installed on both sides of the placement opening, and both of the anti-slip pads 13 are in close contact with the blasting tube 8; a limiting wheel 14 rotatably installed on the bracket 2, and the limiting wheel 14 is in sliding contact with the top of the blasting tube 8.

[0031] In this embodiment, the placement opening at the top of the support plate 12 is adapted to the shape and size of the blasting tube 8, ensuring that the blasting tube 8 can be stably placed on the support plate 12, and the anti-slip pad 13 increases the friction between the blasting tube 8 and the support plate 12, preventing the blasting tube 8 from sliding or shifting due to vibration or shaking during transportation. The limiting wheel 14 further limits the movement range of the blasting tube 8 during transportation, ensuring that the blasting tube 8 always remains in the correct position and posture. At the same time, the rotation design of the limiting wheel 14 can reduce the friction resistance between the blasting tube 8 and the blasting tube 8, making the transportation process smoother. Through the coordinated use of components such as the support plate 12, the anti-slip pad 13 and the limiting wheel 14, the blasting tube 8 can be more effectively fixed and supported to prevent it from sliding or shifting due to vibration or shaking during transportation and charging, thereby improving the stability of charging.

[0032] In a further preferred embodiment of the present invention, a connecting frame 15 is fixedly installed on the top of the connecting plate, a first electric telescopic rod 16 is fixedly installed on the top of the inner wall of the connecting frame 15, and a pressure plate 17 is fixedly installed on the output rod of the first electric telescopic rod 16, and the pressure plate 17 is adapted to the opening at the top of the blasting tube 8.

[0033] In this embodiment, after the blasting tube 8 is loaded, the output rod of the first electric telescopic rod 16 drives the pressure plate 17 to slide, so that the pressure plate 17 flattens the explosives accumulated on the blasting tube 8, thereby facilitating the subsequent sealing operation of the opening of the blasting tube 8. The pressure of the pressure plate 17 can ensure that the explosives can be fully filled into the blasting tube 8, thereby reducing the waste and loss of explosives and improving the charging efficiency.

[0034] In a further preferred embodiment of the present invention, a connecting block 18 is fixedly installed at the bottom of the discharge hopper 11, a second electric telescopic rod 19 is fixedly installed on one side of the connecting block 18, and a sealing plate 20 is fixedly installed on the output rod of the second electric telescopic rod 19. The sealing plate 20 is slidably connected to the discharge hopper 11 and seals the bucket mouth of the discharge hopper 11.

[0035] In this embodiment, when the second electric telescopic rod 19 is extended, the sealing plate 20 will move upward and press tightly against the mouth of the discharge hopper 11 to achieve sealing of the mouth. When the second electric telescopic rod 19 is shortened, the sealing plate 20 will move downward, opening the mouth and allowing the explosives to be discharged from the discharge hopper 11. By cooperating with the second electric telescopic rod 19 and the sealing plate 20, the mouth of the discharge hopper 11 can be sealed and controlled to prevent leakage or overflow of explosives from the mouth, thereby ensuring the safety and stability of the charging process.

[0036] In a further preferred embodiment of the present invention, a limiting plate 21 is fixedly installed on the top of the workbench 1, and a limiting groove is opened on one side of the limiting plate 21. A collecting box 22 is slidingly provided on the workbench 1, and the collecting box 22 is located below the discharge hopper 11 and the pressure plate 17. A limiting rod 23 is fixedly installed on one side of the collecting box 22, and the limiting rod 23 is slidingly connected to the limiting groove. A clamping block 24 is rotatably installed on one side of the limiting plate 21, and the clamping block 24 is in rotational contact with one end of the limiting rod 23.

[0037] In this embodiment, the collection box 22 collects excess explosives or waste generated during the charging process to prevent them from being scattered on the workbench 1 and causing pollution or waste. The cooperation between the limiting rod 23 and the limiting groove can ensure the stable sliding of the collection box 22 on the workbench 1 and prevent it from falling off or shifting. When the collection box 22 slides to a predetermined position, the block 24 can be rotated to make it in close contact with one end of the limiting rod 23, thereby fixing and locking the collection box 22 to prevent it from moving or tipping over during the charging process.

[0038] In summary, compared with related technologies, this device reduces the number of on-site charging personnel, reduces labor intensity, and increases charging output through automated charging, effectively ensuring the sustainability of production.
