Description

Technical Field

[0001] This utility model relates to the field of explosive filling technology, specifically to an emulsion explosive filling assembly. Background Technology

[0002] Powdered emulsion explosives are a new type of emulsion explosive. They are formed by using a water-in-oil emulsion matrix under certain process conditions through strong shearing. The matrix is ​​dispersed in a solution of oxidant with low water content or fine droplets of molten oxidant, and a continuous phase of oil phase solution composed of specific carbonaceous fuel and emulsifier. Then, it is made into powdered ammonium nitrate explosives by methods such as spray powdering, rotary flash evaporation, or cooling and solidification followed by pulverization.

[0003] To ensure the accuracy of blasting, existing powdered emulsion explosives are usually filled manually. The powdered emulsion explosive is filled into the explosive cartridge through a funnel and compacted at the same time to improve the density, uniformity and explosive performance of the explosive. However, when filling different explosive cartridges manually, it is often necessary to pick up and put down the funnel and compaction tools, which is a cumbersome operation and not conducive to the filling of emulsion explosives.

[0016] 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.

[0017] Please see Figure 1-4This utility model provides a technical solution: an emulsion explosive filling assembly, including a base 1, a support plate 2 fixedly connected to the top of the base 1, a limiting plate 3 fixedly connected to one side of the top of the support plate 2, a round shaft 4 fixedly connected to the middle position of the top of the support plate 2, a transmission frame 5 rotatably connected to the round shaft 4, a funnel 6 fixedly installed at one end of the transmission frame 5, a handle 7 fixedly connected to one side of the funnel 6, a storage cylinder 8 fixedly connected to the other end of the transmission frame 5, a return spring 9 fixedly connected to the inner wall of the top of the storage cylinder 8, a pressure plate 10 fixedly connected to the bottom end of the return spring 9, a transmission rod 11 fixedly connected to the center position of the top of the pressure plate 10, the transmission rod 11 passing through the storage cylinder 8, the transmission rod 11 and the storage cylinder 8 being slidably connected, a bracket 12 fixedly connected to the middle position of the support plate 2, a limiting cylinder 13 fixedly connected to one end of the bracket 12, metal spring pieces 14 fixedly connected to the inner walls of both sides of the limiting cylinder 13, and a pressing plate 15 fixedly connected to the ends of the two metal spring pieces 14 away from the limiting cylinder 13.

[0018] A push button is fixedly connected to the top of the transmission rod 11. The push button has an anti-slip design, making it easy to press the transmission rod 11 by squeezing the button. A support seat 16 is fixedly connected to the top of the base 1 corresponding to the extrusion plate 15. The support seat 16 has a stepped structure design, which facilitates the support of the explosive filling cylinder and avoids friction between the explosive filling cylinder and the base. The transmission frame 5 has an L-shaped structure design with chamfered corners, which facilitates the rotation switching between the funnel 6 and the storage cylinder 8 by the L-shaped structure design of the transmission frame 5, reducing the rotation stroke and enabling it to complete rapid rotation and switching. The metal spring 14 has an inclined structure, and the extrusion plate 15 has an arc structure design, which facilitates the extrusion plate 15 to be squeezed by the metal spring 14, so that the two extrusion plates 15 can effectively clamp and fix the explosive filling cylinder.

[0019] Specifically, when using this utility model, the explosive filling cylinder is inserted between two extrusion plates 15. The metal springs 14 on both sides of the inner wall of the limiting cylinder 13 then extrude the explosive filling cylinder by extrusion plates 15. At this time, the powdered emulsion explosive is filled into the explosive cylinder through the funnel 6. After filling, the funnel 6 is rotated by the handle 7. The funnel 6 then drives the transmission frame 5 to rotate around the circular shaft 4. The rotating transmission frame 5 then drives the limiting cylinder 13 to rotate. When one side of the transmission frame 5 is tightly attached to the limiting plate 3, the transmission frame 5 drives the limiting cylinder 13 to move to the top of the explosive cylinder. At this time, the pressing button is pressed. The pressing button then drives the pressure plate 10 to move downward through the transmission rod 11. The moving pressure plate 10 stretches the return spring 9. At the same time, the moving pressure plate 10 compacts the powdered emulsion explosive at the top of the explosive cylinder, thereby improving the density, uniformity and explosive performance of the explosive. After pressing, the return spring 9 drives the pressure plate 10 and the transmission rod 11 to return to their original positions.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
