Description

Technical Field

[0001] The utility model belongs to the technical field of ammunition tooling, and specifically discloses a light mortar ammunition taking device. Background Art

[0002] As a new type of guided ammunition, mortar-guided ammunition has irreplaceable advantages in the combat field. It has the characteristics of flexible and rapid deployment of traditional mortar ammunition and the ability to attack the top of the target at a large angle of attack, as well as the ability of precision-guided ammunition to accurately strike the target.

[0003] The light mortar launch platform is a commonly used mortar launch platform, and its barrel is a smoothbore gun structure, that is, the inside of the barrel is a smooth cylindrical surface. The characteristic of the light mortar is front loading, which requires the ammunition to be loaded from the front of the barrel and slide freely to the bottom of the barrel by gravity. After sliding into the bottom of the muzzle, it is divided into two firing modes: pull-fire and forced-fire. The pull-fire is driven by the gunner to pull the gun rope to drive the firing pin to fire the primer and the propellant. The forced-fire is driven by the ammunition falling into the bottom of the mortar by its own weight. The primer at the bottom of the ammunition hits the firing pin by gravity to fire the primer and the propellant. Both firing modes have the possibility that the primer and the mortar firing pin cannot completely and reliably collide. At this time, a device that can safely and reliably remove the unfired guided ammunition from the front of the mortar muzzle is needed. The head of the mortar guided ammunition is equipped with a guidance head and electronic control components. Due to the limitation of the internal space, the external structure of the projectile body cannot adapt to the ammunition extraction device of conventional ammunition. Therefore, a retrieval device that can adapt to the head structure of guided ammunition is needed.

[0004] During the process of extracting ammunition, if the guided ammunition is not firmly fixed to the extracting device, there is a risk that the guided ammunition will fall off from the extracting device, and the fallen guided ammunition may slide back into the bottom of the barrel and fire accidentally, which will pose a safety threat to the personnel who are performing the extracting operation. Therefore, a device is needed to safely remove guided ammunition from the front of the mortar muzzle.

[0005] Based on the above needs, it is necessary to design a light mortar ammunition extraction device that can adapt to the head of the guided ammunition and can also remove the guided ammunition safely and reliably. Utility Model Content
