Description

Technical Field

[0001] This utility model belongs to the technical field of explosive loading equipment for blasting engineering, and specifically relates to a device for filling emulsion explosives after drilling. Background Technology

[0002] In open-pit mining, tunnel excavation, and earthmoving blasting projects, after drilling, emulsion explosives need to be filled into the borehole and detonators need to be installed. Traditional operations usually rely on manual labor for loading explosives and installing detonators, which results in low efficiency and poor safety. Although mechanized filling devices can improve efficiency, existing equipment still suffers from insufficient detonator installation accuracy, waste of explosive residue, and low reliability of detonator placement. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a filling device for emulsion explosives after drilling, which simultaneously realizes efficient filling of emulsion explosives, precise placement of multi-segment detonators, and scraping of residual explosives.

[0004] To achieve the above objectives, this utility model provides the following technical solution: This utility model includes a track structure, an explosive pump, a filling moving seat, a filling rod, and a material removal structure; the filling rod extends from the filling moving seat and has a propellant hole for conveying emulsion explosive along the filling rod; the explosive pump outputs emulsion explosive and conveys it to the end of the filling rod via the filling moving seat; the material removal structure includes a material removal pipe, which is slidably disposed on the outside of the filling rod.

[0005] Optionally, a track structure is also included, wherein the filling moving seat is moved and mounted on the track structure by a motor drive.

[0006] Optionally, the material removal structure further includes a material removal moving vehicle, which is driven by a motor to move on the track structure.

[0007] Optionally, a tube insertion hole for filling the detonator is also provided along the filling rod.

[0008] Optionally, there are two insertion holes, which are located parallel to each other on both sides of the medicine hole.

[0009] Optionally, it also includes a number of filling telescopic cylinders equal to the number of the insertion holes; the filling telescopic cylinders are mounted on the filling moving seat; the end of the filling telescopic cylinder is fixedly provided with a push rod for pushing out the detonator in the insertion hole.

[0010] Optionally, a rubber scraper ring is provided on the inner side of the discharge pipe.

[0011] Optionally, the rubber scraper ring is fixedly mounted on the inner side wall of the discharge pipe near the end of the filling rod.

[0012] Optionally, the material removal structure further includes a pipe support frame; the pipe support frame is fixed to the end of the track structure; the material removal pipe is slidably disposed on the pipe support frame.

[0013] The beneficial effects of this utility model are as follows: This device is used to fill the borehole with emulsion explosives and detonators after drilling. With the movement of the filling moving seat, the filling rod extends into the borehole, eventually reaching the bottom. Through the operation of the explosive pump, the emulsion explosives flow out through the output end of the filling tube and gradually fill the borehole to the required depth. Before the filling rod extends in, the detonator is placed in the insertion hole and extends into the borehole with the filling rod. After the emulsion explosives are filled, the device moves with the retraction of the filling rod. After the filling rod moves upward a certain distance, it pushes the filling telescopic cylinder, thus releasing the detonator. The detonator is pushed out of the insertion hole and retained inside the emulsion explosive. In this embodiment, two insertion holes are provided, which can be used to place the detonator in the lower and upper sections of the emulsion explosive section to ensure successful detonation. By moving the material removal vehicle, the material removal tube is moved into the borehole outlet and fixed in position. As the filling rod retracts, the emulsion explosive attached to the surface of the filling rod is scraped off by the rubber scraper and flows back into the hole. This device can prevent most of the emulsion explosive from moving out of the borehole with the filling rod, saving emulsion explosive and avoiding the safety hazards caused by the emulsion explosive being exposed on the equipment.

The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0018] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0019] This utility model provides a device for filling emulsion explosives after drilling, such as Figures 1-4 As shown, the device includes a track structure 1, an explosive pump 2, a filling moving seat 3, a filling rod 4, and a material removal structure 5. The filling moving seat 3 is movably mounted on the track structure 1. The filling rod 4 extends from the filling moving seat 3. The explosive pump 2 outputs emulsion explosive, which is conveyed to the end of the filling rod 4 via the filling moving seat 3. An explosive hole 41 for conveying the emulsion explosive and a tube hole 42 for filling detonators are provided along the filling rod 4. The device also includes a number of filling telescopic cylinders 6 equal to the number of tube holes 42. The filling telescopic cylinders 6 are mounted on the filling moving seat 3. A stop rod 7 is fixedly provided at the end of the filling telescopic cylinder 6, and the stop rod 7 extends along the tube hole 42. When the filling telescopic cylinder 6 extends, it drives the push rod 7 to push out the detonator placed at the end of the insertion hole 42; the material removal structure 5 includes a material removal pipe 51, a material removal moving vehicle 52, and a pipe support frame 53; the pipe support frame 53 is fixed to the end of the track structure 1; the material removal pipe 51 is slidably disposed on the pipe support frame 53; the material removal moving vehicle 52 is movably disposed on the track structure 1; the material removal pipe 51 is slidably disposed on the outside of the filling rod 4 and can slide along its axial direction; a rubber scraper ring 54 is provided on the inner side of the end of the material removal pipe 51, and the rubber scraper ring 54 is fixedly disposed on the inner side wall of the material removal pipe 51 near the end of the filling rod 4.

[0020] This device is used to fill the borehole with emulsion explosives and detonators after drilling. As the filling moving seat 3 moves, the filling rod 4 extends into the borehole, eventually reaching the bottom. Through the operation of the explosive pump 2, the emulsion explosives flow out from the output end of the filling tube and gradually fill the borehole to the required depth. Before the filling rod 4 extends, the detonator is placed in the insertion hole 42. After the emulsion explosives are filled, the detonator moves with the retraction of the filling rod 4. After the filling rod 4 moves upward a certain distance, it pushes the filling telescopic cylinder 6, thus pushing the detonator out of the insertion hole 42. To prevent the emulsion explosive from being trapped inside, two placement holes 42 are provided in this embodiment. The detonator can be placed in the lower and upper sections of the emulsion explosive section to ensure successful detonation. By moving the material removal vehicle 52, the material removal pipe 51 is partially moved into the borehole outlet and fixed in position. As the filling rod 4 retracts, the emulsion explosive attached to the surface of the filling rod 4 is scraped off by the rubber scraper ring 54 and flows back into the hole. This device can prevent most of the emulsion explosive from being moved out of the borehole with the filling rod 4, saving emulsion explosive and avoiding the safety hazards caused by the emulsion explosive being exposed on the equipment.
