Mortar launching device

Abstract

The invention discloses a mortar launching device. The device comprises a mortar breech, an elastic part, a blocking part, and a barrel shaped tube with a bore, wherein the breech is mounted at one end of the tube; a firing pin positioned in the bore is arranged on the breech; the blocking part comprises a shaft sleeve, and a heading which is arranged at the outer side of the shaft sleeve; the shaft sleeve sleeves the firing pin; the first end of the elastic part is arranged against the blocking part, and while the second end of the elastic part is arranged against the breech; at least one first exhaust hole is formed in the breech; when the elastic part is in the original state, the first exhaust hole is communicated with the bore; when the elastic part is compressed, the first exhaust hole is blocked through the beading. With the adoption of the device, a mortar can reliably downwards slide; the inside diameter of the tube under small gaps is adopted on the premise that the air can be exhausted through the first exhaust hole in the breech; therefore, the initial speed of the mortar can be increased, the firing range can be expanded, and meanwhile, the launching precision can be efficiently improved.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of muzzle loading mortars, in particular to a mortar launching device. Background technique [0002] Such as figure 1 As shown, in the traditional mortar, the shell is loaded from the muzzle, and then the shell slides down the barrel by its own gravity and hits the firing pin at the bottom to fire, and the gas generated by the shell is discharged from the muzzle. In order to allow the compressed gas in the barrel to flow out smoothly when the shell slides down without affecting the downward speed of the shell, there must be a gap between the shell and the wall of the bore, that is to say, the diameter of the shell is smaller than the inner diameter of the barrel, which is the purpose of muzzle loading. A necessary condition for shells. [0003] The air under the shell needs to be discharged upwards from the gap between the shell and the bore wall, so it takes a certain amount of t...

Problems solved by technology

[0005] The existence of the gap also affects the centering of the shell in the chamber, causing the fired shell to swing when it moves along the barrel, and the amount of gunpowder gas leakage of each shell is inconsistent, resulting in the dispersion of the muzzle velocity, which reduces the shooting accuracy of the shell.

[0006] To sum up, if the gap between the shell and the bore wall is large, the rate o...
