Technical Field

[0001] The utility model relates to the technical field of fireworks production, in particular to a mud bottom structure for a fireworks tube. Background Art

[0002] The fireworks manufacturing process involves a step called "mud-bottoming," which involves filling the bottom of the firework tube with an appropriate amount of soil and compacting it. The mud bottom of the firework tube affects the quality of the fireworks. Combination fireworks are generally made by bundling multiple firework tubes before the mud-bottoming step. Workers usually place the filled firework tubes on a mud-bottoming workbench for compaction, making it difficult to accurately press down combination fireworks of different shapes, and the pressing operation is laborious. Utility Model Content

At the same time, the pressing operation is more labor-saving, and can effectively solve the problems in the background technology.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

[0005] The top of the two lifting connecting rods is connected to the pressure support frame, and the detachable mud bottom supporting plate is installed on the bottom surface of the mud bottom supporting plate.

[0006] As a preferred technical solution of the present invention, first plug-in grooves cooperating with the positioning plate of the combined firework tube are provided on both side surfaces of the firework tube fixing seat.

[0007] As a preferred technical solution of the present invention, second plug-in grooves cooperating with the mud bottom support plate are provided on both side surfaces of the downward pressure support frame.

[0008] As a preferred technical solution of the present invention, the rear sides of the firework tube fixing seat and the downward pressure support frame are both provided with adsorption protrusions.

[0009] As a preferred technical solution of the present invention, the front side surfaces of the combined firework tube positioning plate and the mud bottom support plate are both provided with plug-in protrusions.

[0010] As a preferred technical solution of the present invention, the lower parts of the circumferences of the two lifting connecting rods are connected with a limit plate, and the limit plate is located below the mud bottom working platform.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The mud bottom structure for a fireworks tube facilitates replacement of the combined fireworks tube positioning plate and the mud bottom support plate by providing a fireworks tube fixing seat, a downward pressing support frame, a first plug-in slot and a second plug-in slot, thereby accurately pressing down combined fireworks of different shapes, thereby improving work efficiency. The downward pressing support frame, a return spring, a lifting connecting rod and a foot pedal are provided to facilitate users in compacting the mud bottom of the fireworks tube, and the downward pressing operation is relatively labor-saving. After the downward pressing operation is completed, the mud bottom support plate can be automatically reset under the elastic force of the return spring. BRIEF DESCRIPTION OF THE DRAWINGS
