Rigid ejection mechanism and ejection method for a shotgun

Abstract

The invention provides a hunting gun rigid ejection mechanism which comprises a cartridge receiver, a case pulling hook and an ejection piston. The case pulling hook is mounted on one side of the cartridge receiver, the ejection piston is mounted on one side, opposite to the case pulling hook, of the cartridge receiver, an inward claw portion is arranged on the inner side of the end of the case pulling hook and used for hooking an ejection shell, close to one side of the bottom, of a cartridge case during ejection and pulling to a direction away from the cartridge case, a step corresponding tothe claw portion of the case pulling shell is arranged at the top of the ejection piston, and a flat plate on the lower portion of the step is arranged to be a chamfered bevel. The invention furtherprovides a hunting gun rigid ejection method. The step is arranged at the top of the ejection piston, and the flat plate on the lower portion of the step is provided with the chamfered bevel, so thatthe lateral side of the bottom end face of the cartridge case is pulled by the case pulling hook to collide with the bevel during ejection, the end face, close to the lateral side, of the bottom of the cartridge case collides with a slope crest line of the step, and ejection is completed after the cartridge case rotates around the slope crest line by a certain angle and moves along the bevel by acertain distance. Hunting gun ejection reliability can be improved by the hunting gun rigid ejection mechanism.

Description

technical field [0001] The invention relates to an automatic weapon shell extracting mechanism and an extracting method, in particular to a hunting rifle rigid shell extracting mechanism and an extracting method. Background technique [0002] At present, the way that the shell case of automatic weapons is removed from the gun chamber is as follows: the bottom of the ordinary shell case is a cylindrical portion with an annular ejection groove, and the automatic machine head of the weapon has a cylindrical bottom socket, which is exactly the bottom cylinder of the shell case and The shell extraction groove 1 can fall into the shell bottom nest, and there is a shell hook on one side of the shell bottom nest. Driven by the pulling force, the cartridge moves backwards, and the cartridge casing moves back from the barrel with the automatic machine under the restriction of the pulling hook until it is completely moved out of the barrel. [0003] The ejection of general firearms is...

AI Technical Summary

Problems solved by technology

[0006] Therefore, there is a significant difference in the ejection of shotguns and ordinary cartridges. Under the same recoil speed V0 of the gun, the energy of ejection of shotgun cartridges is smaller, the anti-interference ability of the cartridge case is poor, and the flight is unstable, which leads to the reduction of the reliability of subsequent ejection. , prone to jamming
