Description

Technical Field

[0001] The utility model relates to the technical field of artificial recoil devices for artillery, and in particular to a portable artificial recoil device for artillery. Background Art

[0002] The artillery recoil device, also known as the "recoil and recuperator", is composed of a recoil mechanism and a recuperator, etc.; it is an artillery component that elastically connects the gun barrel and the gun carriage to reduce the force on the gun carriage during firing; artificial recoil of the artillery refers to the activity of using an artificial recoil device to make the recoil part of the artillery recoil during the assembly, use or maintenance of the artillery. The purpose of this process is to check the performance of the artillery recoil device and the automatic breech opening action of the breech block, etc.

[0003] There are two existing artificial recoil devices. One is a screw-type artificial recoil device, which entirely relies on manual rotation of the nut to drive the screw to pull the gun breech to recoil; the other is a hydraulic artificial recoil. During operation, personnel need to run back and forth up and down. By operating the double-purpose pump, the recoil liquid is injected into the inner cylinder of the recuperator through the conduit and connector to achieve artificial recoil. Currently, the two existing artificial recoil devices are not convenient for manual operation and are time-consuming and laborious. Summary of the Utility Model
