Problems solved by technology

Although these two impact-type shell-extraction mechanisms are simple in structure and easy to manufacture, their shell-extraction action is intense, and the shell-extraction time is very short between 6-10 milliseconds. Part wear, cartridge breakage and other problems will affect the use of artillery

Abstract

The invention discloses a shock-absorbing gentle type automatic casing extracting device, which comprises a pumping bobbin and a cam. The front end is equipped with a shell claw to cooperate with the bottom edge of the cartridge, and the rear end of the pumping tube is close to the upper contour surface of the cam. The lower end of the cam is hinged to the upper end of the first connecting rod, and the lower end of the first connecting rod is connected with the second connecting rod and the third The upper end of the connecting rod is hinged, the lower end of the second connecting rod is hinged with the slider, one end of the slider is connected with one end of the compression spring, the slider is located in the chute of the chute plate, and the chute plate is installed in the direction of the other end of the slider There is a shell template, the other end of the compression spring is connected with the gun body, and the lower end of the third connecting rod is hinged with the gun body. The shock-absorbing and gentle automatic shell extracting device of the present invention can avoid multiple violent collisions, overcome problems such as yielding and fracture of shell extracting parts, and make the shell extracting process relatively stable.

Description

technical field [0001] The invention relates to an auxiliary device for artillery, in particular to a shock-absorbing and gentle automatic shell extraction device. Background technique [0002] At present, artillery-related technologies have been more and more used in civilian fields: not only for mine blasting, but also for opening mountains and repairing roads, and can even be used to extinguish high-rise fires by launching fire-fighting projectiles, bringing people Great convenience and security. [0003] For large and medium-caliber artillery, the most likely problem in the shooting process is that the shell extraction mechanism cannot successfully complete the shell extraction action after shooting, resulting in that the shell casing cannot be pulled out in time. If it is at the emergency scene, it will directly affect the continued use of the artillery, and even Affect disaster control and engineering progress. [0004] Most of the existing artillery adopts the percu...
