a launcher

Abstract

The embodiment of the invention provides a launching device. By adoption of the launching device, the problem that in the prior art, high-pressure air enters a gun barrel unstably and the shot acceleration is relatively slow can be solved. The launching device comprises an air chamber, an air control device, a launching mechanism and the gun barrel, wherein the air control device and the launchingmechanism are positioned inside the air chamber; and the gun barrel and the air chamber are connected. According to the launching device provided by the embodiment of the invention, an impact hammeris pushed through pressure on two sides of the impact hammer to impact a piston rod at high speed, so that the high-pressure air can instantly enter the gun barrel at the maximum flow rate to push a shot body or a birdshot for being launched; the motion of a piston is achieved when the piston is impacted by the impact hammer through the air floating effect, so that the operation can be flexible, the reliability can be high, and the problem about the resistance to the motion of the piston can be solved; furthermore, the motion speed of the piston is higher, so that the air inlet section where the high-pressure air enters air cavities can instantly reach the maximum, and then the high-pressure air can instantly enter the gun barrel at the maximum flow rate; and accordingly, the constant-pressure and constant-acceleration process that the high-pressure air enters the gun barrel to push the shot body or the birdshot can be guaranteed.

Description

technical field [0001] The invention relates to a launch technology, in particular to a pneumatic ram type air cannon launch device. Background technique [0002] refer to figure 2 , Document 1 "Research and Design of Impact Sliding Valve Firing Mechanism, Mechanical Manufacturing [J], 44 (500) (2006) 26-28" discloses a kind of air cannon firing mechanism for firing bird bombs, which includes a barrel 4. Air blocking head 15, piston connecting rod 31, piston 33, small air intake channel 17, intake nozzle 3, deflation nozzle 2, left air chamber 13, right air chamber 14, high pressure chamber 16, air storage chamber Connect pipe 22, spring 18 and cylinder 20. The assembly relationship requires that the air blocking head 15 is sealed with the end of the gun barrel 4, the high-pressure chamber 16 is sealed with the left air chamber 13 and the gas does not communicate with each other, the piston 33 is sealed with the inner wall of the cylinder 20, and the right air chamber 14 i...
