Shell firing device with variable firing range used for training

Abstract

The invention discloses a shell firing device with a variable firing range used for training. The device comprises a machine body and a shell filling barrel. A barrel cavity, communicating leftwards and rightwards, is arranged in the shell filling barrel. The shell filling barrel is fixedly installed on the left end surface of the machine body. A first sliding groove is arranged in the machine body. The center of the left end wall of the first sliding groove is equipped with a first through hole communicating with the first sliding groove and the barrel cavity. A rectangular groove, extendingrightwards, is arranged in the right end wall of the first sliding groove. A rectangular block is slidably installed in the rectangular groove. A first sliding block is installed in the first slidinggroove in a slidable manner. The center of the left end surface of the first sliding block is fixedly equipped with a push block used for pushing shells. The center of the left end surface of the pushblock is fixedly equipped with a hitting column acted upon shell primers. The first sliding block is fixedly equipped with a first driving motor. The right end of the first driving motor is equippedwith a first threaded rod which extends rightwards in a power manner.

Description

technical field [0001] The invention relates to the technical field of cannonball launching, in particular to a training cannonball launching device with variable range. Background technique [0002] Shells refer to ammunition with a caliber of more than 20mm that is launched by artillery to complete killing, blasting, penetration and other tactical purposes. It usually includes several parts such as hood, projectile (warhead), fuze, belt, primer and cartridge (contained propellant). When soldiers train, they often use empty shells, that is, the shell body is not filled with explosives. Consistent with real shells, the range of traditional shells mainly depends on the booster of the launcher and the amount of gunpowder fired, and the amount of gunpowder fired has been fixed when the shell is formed, and the traditional launcher is difficult to adjust the booster, which cannot be used for training. Contents of the invention [0003] Aiming at the deficiencies of the abov...
