Abstract

Disclosed is a long backseat pipe withdrawing type semi-automatic howitzer emitter capable of combination with light arms, characterized in that, a transmitting tube mounted with a gap vertically in the guide post bushing, a gun bolt case and a gun bolt body are formed into the backseat of the emitter. A swing block iron of the rigid interlocking gear can make and break by the push of the relative working face on the guide strike needle. When the shrapnel is emitted, the backseat simultaneously oppresses the big and small recoil check spring backseat to move to the place. When performing counterrecoil, the holdback blocks the guide strike needle to make the guide strike needle and the gun bolt body generate an amount of relative displacement and after the breech lock adducts inwards to form the unlocking shape and the joint gun bolt body also stops the counterrecoil. When the transmitting tube gun bolt casing is pushed counterrecoil by the large spring and socks away the cartridge case, the emitter is in a state with the boring open waiting to attract. The blocked guide strike needle and the joint gun bolt case are released when shooting, in the push of the small counter-recoil spring, the gun bolt case counterrecoil is pushed into the boring. The slave guide strike needle moves forward due to the self inertia and opens the block iron to finish the closedown and then strike the shrapnel primer. The shooting cycle is semi-automatic.
