    • An automatic primer feed mechanism for use with a carrier assembly of a large caliber artillery piece, which includes mechanical assemblies for automatic primer loading after full breech closure and allows for spent primer cartridges to be extracted before opening of the breech to maximize safety, thereby allowing the gun crew to perform artillery piece misfire, sticker and check fire operations before the breech is opened. The mechanism includes a body member that mounts the automatic feed mechanism to the carrier of the artillery piece so as to interface with the carrier to position the mechanism on one side of the breech of the artillery piece. The body member includes a cam surface member, which provides a path for movement of an injection arm member. The tray member has guide rails for engagement with the body, which slides in relation thereto. A magazine containing a plurality of primer cartridges, which inserts in a receiver channel located in the tray member. The mechanism provides improved safety wherein live primers stored in a magazine are at a distance from the firing chamber hole that prevents flame from reaching a live charge before a fresh primer is injected therein.
    • 一种用于大口径火炮部件的载体组件的自动底漆进给机构,其包括用于在完全后膛关闭之后自动底漆装载的机械组件,并且允许在打开后膛之前抽出废底漆以最大化安全性,从而允许 枪手在炮膛打开之前进行炮兵炮击,贴上贴纸并检查火灾作业。 该机构包括:主体部件,其将自动进给机构安装到火炮的支架上,以与支架相接触,以将机构定位在火炮的后膛的一侧。 主体构件包括凸轮表面构件,其提供用于注射臂构件的移动的路径。 托盘构件具有用于与主体接合的导轨,其相对于其滑动。 一种包含多个底漆盒的盒子,其插入位于托盘构件中的接收器通道中。 该机构提供了改进的安全性,其中储存在料盒中的活性底漆距离燃烧室孔一定距离,防止火焰在其中注入新鲜底漆之前达到带电荷。
