Shell withdrawing structure for sitting force-free cannon

Abstract

The invention relates to a mechanical automatic ejection structure of a sitting force-free gun, which can be used on a launching device of the sitting force-free gun, and belongs to an ejection structure for the sitting force-free gun. An ejection structure for a sitting force-free gun comprises an ejection hook, a fixing screw, a spring and a latch shaft. The ejection hook is of a stepped shaft structure, the end face of the large-diameter section is provided with an inclined face, and the side face of the large-diameter section is provided with a positioning guide groove. The ejection hook is inserted into the latch shaft, and is inserted into the positioning guide groove from the outside of the latch shaft through the fixing screw; the small-diameter section is sleeved with the spring, and the spring is used for preventing the ejection hook from interfering with locking when the ammunition is loaded in place and locked. The ejection structure is simple in overall structure and safe to use, and automatic mechanical ejection can be achieved in the operation process.

Description

technical field [0001] The invention belongs to an ejection structure for a recoilless gun, and is a mechanical automatic ejection structure for a recoilless gun, which can be used in a launching device of a recoilless gun. Background technique [0002] After the recoilless gun has fired the projectile, the shell of the projectile will be deformed by heat and pressure, making it fit the gun bore, making it difficult to take out the shell, making it difficult to launch the next round of ammunition, which will affect the firepower output of the artillery. The traditional shell extraction method generally uses other mechanisms or parts to manually remove the shell. This shell extraction method increases the shooter's operation steps, prolongs the time for the shooter to launch ammunition, and weakens the firepower output during combat time. Contents of the invention [0003] The purpose of the present invention is to provide an ejection structure for a recoilless gun. [000...
