Abstract

The invention discloses an ammunition conveying mechanism of a chain type ammunition feeding machine gun with simple structure and few friction surfaces. The ammunition conveying mechanism comprises amachine frame and a receiver, and is characterized in that the side wall of the machine frame is provided with a first working surface and a second working surface which extend forwards and backwardsand are perpendicular to each other, the first working surface of the machine frame is a curved surface, the horizontal projection of the first working surface is a curve, the second working surfaceof the machine frame is provided with a reset groove which extends forwards and backwards, and the horizontal projection of the reset groove corresponds to the horizontal projection of the first working surface of the machine frame; and the ammunition conveying mechanism further comprises a rammer base, a rammer lever and rammer teeth, wherein the rammer base is fixed on the receiver, the rammer lever is hinged on the rammer base through a first rotating shaft extending forwards and backwards, the rammer teeth are hinged on the upper end of the rammer lever through a second rotating shaft extending forwards and backwards, a torsion spring for resetting the rammer teeth is arranged on the second rotating shaft, a roller which is in rolling fit with the first working surface of the machine frame is arranged at the lower end of the rammer lever, and a reset projection which is in sliding fit with a reset groove of the machine frame is arranged on the rammer lever.

Description

technical field [0001] The invention belongs to the technical field of machine gun ammunition feeding mechanism, and relates to a chain type ammunition feeding mechanism of a machine gun. Background technique [0002] The ammunition feeding mechanism of the chain feed machine gun is an important mechanism of the machine gun, which is directly related to the reliability of the overall work of the machine gun. The existing machine gun ammunition feeding mechanism, such as the patent application number "201711374043.6" and the name "a small and medium-caliber machine gun ammunition feeding mechanism", uses a series of components such as "shift lever, shift fork, and small lever structure" to drive " "Pluck the crank" and "pick the crank" to translate the ammunition from left to right. Not only is the transmission complicated, but there are many friction surfaces, and it is inconvenient to use and maintain. Contents of the invention [0003] The purpose of the present inventi...
