[0002] Fireworks are a traditional festive product in my country, with a very long history of production and folk customs. As the birthplace of fireworks and firecrackers, my country is also the world's largest producer and exporter. With the improvement of people's living standards, the demand for fireworks and firecrackers has also increased. The basic structure of fireworks includes a launching tube with its bottom sealed with a layer of soil, a fuse hole penetrating the center of this soil layer for connecting the fuse, and then the soil layer is filled with materials such as gunpowder, plugs, effect powder, and sealing layers.

[0003] When adding soil to the inside of the cannon barrel for compaction, the traditional method is to do it manually. This is not only time-consuming and labor-intensive, but also inefficient. Manual compaction can easily damage the cannon barrel, which increases production costs, affects production efficiency, and makes it inconvenient to use. Utility Model Content

Manual compaction can easily damage the tube, thereby increasing production costs and affecting production efficiency, and is inconvenient to use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes an operating table and an L-shaped bracket mounted on the upper surface of the operating table. The bracket has mounting holes, and a stirring cylinder is installed within these holes. A motor is mounted on the upper surface of the stirring cylinder. A rotating shaft is rotatably mounted on the inner top surface of the stirring cylinder. The top end of the rotating shaft extends through the stirring cylinder and is fixedly connected to the output shaft of the motor. Several stirring rods are mounted on the outer surface of the rotating shaft. A feeding frame is connected to the upper surface of the stirring cylinder, and a discharge pipe is connected to the bottom end of the stirring cylinder. A solenoid valve is mounted on the discharge pipe. An electric push rod is mounted on the lower surface of the horizontal portion of the bracket. A compaction plate is detachably mounted on the output shaft end of the electric push rod via a mounting assembly. A groove is formed on the upper surface of the operating table, and a threaded rod is rotatably mounted within the groove. One end of the threaded rod extends through the operating table and is mounted on a rotating plate. A slide is threaded onto the threaded rod, and a clamping assembly is provided on the upper surface of the slide.

[0006] By adopting the above scheme, a mixing drum, a rotating shaft, an electric push rod, and a threaded rod are set up. The rotating shaft is driven by a motor, which works in conjunction with the mixing rod to facilitate real-time mixing of the soil in the mixing drum, preventing soil clumping and allowing the soil to be discharged smoothly. The threaded rod and the slide block facilitate the movement of the barrel. The electric push rod drives the compaction plate to compact the soil in the barrel, thus saving time and labor, improving the production efficiency of the barrel, reducing costs, and making it convenient to use.

Rotating plate drives threaded rod 3 to rotate. Rotate the drive slide 4 to move, the slide 4 drives the support plate 5 to move, the support plate 5 drives the barrel to move. When the barrel is moved below the compaction plate 11, stop rotating the plate, then start the electric push rod 10. The electric push rod 10 drives the compaction plate 11 to move downward. The compaction plate 11 enters the barrel to compact the soil. Then reset the compaction plate 11 and remove the barrel. When it is necessary to clean the soil below the compaction plate 11, move the operating plate 26. The operating plate 26 moves forward and drives the slide rod to move. The slide rod drives the scraper 27 to move forward. The top of the scraper 27 abuts against the lower surface of the compaction plate 11. As the scraper 27 moves, it scrapes and cleans the soil at the bottom of the compaction plate 11. At this time, the soil falls into the collection frame 22. When it is necessary to disassemble the collection frame 22, move the pin 24. One end of the pin 24 moves out of the slot, and then the collection frame 22 can be removed.
