Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. The propellant powder comprises a cartridge, 2 parts of primer, 3 parts of black gunpowder, 4 parts of mono-camphor-11A-8/1 propellant powder, 5 parts of mono-base 5/7 propellant powder, 6 parts of nitrocellulose paper board, 7 parts of hard paper cover plate.
Detailed Description
The present invention will be described with reference to the accompanying drawings.
As shown in figure 1, the charging structure for the high-chamber pressure artillery comprises a medicine cylinder 1, a primer 2, a black gunpowder package 3, a single camphor-11A-8/1 propellant 4, a single base 5/7 propellant 5, a nitrocellulose paper board 6 and a hard paper cover plate 7, the cartridge 1 is a cone frustum shaped shell with an open upper part, the primer 2 is fixedly arranged at the bottom of the cartridge 1, the black fire explosive bag 3 is fixedly arranged at the upper part of the primer 2, the single camphor-11A-8/1 propellant powder 4 is arranged at the periphery in the cartridge 1, the single base 5/7 propellant powder 5 is arranged at the central part in the cartridge 1, the nitrocellulose paper board 6 is arranged between the single camphor-11A-8/1 propellant powder 4 and the single base 5/7 propellant powder 5, and closely contact with the two, the cardboard cover plate 7 is arranged on the upper part of the single base 5/7 propellant powder 5; the cartridge 1 is made of brass, the thickness is 3mm, the diameter of the bottom surface is 55mm, and the diameter of the top surface is 38 mm; the primer 2 is military No. 8 primer; the single camphor-11A-8/1 propellant 4 is military propellant and is 90mm long; the single-base 5/7 propellant is 5 military-standard propellant, and is a typical granular propellant; the nitrocellulose paper board 6 can be cut according to the filling requirement; the hard paper cover plate 7 is a common civil corrugated board, the thickness of the hard paper cover plate is 3mm, and the hard paper cover plate is cut according to the loading amount.
When the firework powder launching device is used, the primer 2 is rotationally arranged in the medicine cylinder 1, then the black firework powder bag 3 is arranged, the black firework powder bag 3 is placed in the middle and is tightly combined with the medicine cylinder 1 and the primer 2, the periphery in the medicine cylinder 1 is filled with the mono camphor-11A-8/1 launching powder 4, the uniform filling is required, no gap exists, then the mono camphor-11A-8/1 launching powder 4 is sealed by using the nitrocotton paper board 5, and after the mono camphor-11A-8/1 launching powder 5 is filled according to the requirement, the hard paper cover plate 7 is used for sealing at the upper part.
