Abstract

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to the field of armament, namely, to the mechanisms for supplying cartridges of automatic weapons with ribbon feeding. Mechanism for feeding cartridges of automatic weapons with belt feed contains an axially rotating feed lever with a spring loaded feeder and a limiter. Mechanism for the supply of cartridges is also provided with a cutter hinged on the lid and configured to interact with the cartridge belt. Cutter is a spring-loaded two-arm lever with a profile surface interacting with the feed lever. At the end of the feeding of the cartridge belt, one shoulder of the cutter interacts with the cartridge belt, the other arm interacts with the lid.

EFFECT: improved reliability of the cartridge feed mechanism is achieved.

Description

The invention relates to automatic weapons and can be used in feed mechanisms of automatic weapons with tape power.

In all samples of automatic weapons with tape-fed ammunition, when the cartridge belt is fed, the cartridge belt is inertially moved inside the automation of the product, which reduces the reliability of the mechanism for supplying the weapon sample.

The known mechanism for supplying cartridges of a 30 mm automatic grenade launcher on an AGS-17 machine (see Manual for a 30 mm automatic grenade launcher on an AGS-17 machine, USSR Ministry of Defense, Moscow, 1982, http://forum.guns.ru/ forummessage / 18 / 140174.html), selected as the closest analogue, containing a rotating feed lever with a spring-loaded feed and limiters. The stops are two locking fingers located on the cover. When the shutter moves forward, the feed lever moves to the right and the feeder goes behind the next cartridge, the guards keep the tape from moving back inside the weapon. When the shutter recovers after a shot, the feed lever moves to the left and the feeder moves the tape one step, the next cartridge rests against the special projections of the receiver and is installed on the lower line. In the magazine box, attached to the grenade launcher, there is a protruding plate element to eliminate the inertial movement of the cartridge strip when feeding inside the weapon.

The disadvantage of this design is the low reliability of the cartridge feeding mechanism, since the protruding plate element does not completely eliminate the inertial movement of the cartridge strip inside the weapon.

The technical task of the invention is to increase the reliability of the feed mechanism of the cartridge strip.

The technical result consists in the complete exclusion of the inertial movement of the cartridge belt inside the weapon when feeding the cartridge tape.

The problem is achieved in that the feed mechanism of the cartridges of automatic weapons with tape power contains a rotating on the axis of the feed lever with a spring-loaded feeder, a limiter. The cartridge feed mechanism is equipped with a cutter pivotally mounted on the lid and configured to interact with the cartridge strip, the cutter is a spring-loaded two-arm lever with a profile surface that interacts with the feed lever, and at the end of the cartridge ribbon supply one cutter shoulder interacts with the cartridge ribbon, the other shoulder interacts with the cover.

The invention is illustrated by drawings, which depict:

figure 1 - General view of the weapon - the position of the parts of the feed mechanism at the beginning of the supply of cartridge strip per step;

figure 2 - top view of the weapon - the position of the parts of the feed mechanism at the beginning of the supply of cartridge strip per step;

figure 3 - General view of the weapon - the position of the parts of the feed mechanism at the end of the supply of cartridge strip per step;

figure 4 is a top view of the weapon - the position of the parts of the feed mechanism at the end of the supply of cartridge strip per step.

The feed mechanism for cartridges of automatic weapons with a tape supply contains a feed lever 1 of a cartridge belt 2 with a spring-loaded feeder 3. In the cover 4, which is not fixed during firing, on the axis 5 there is a cutter 6 with a spring 7, on the axis 8 there is a limiter 9 with a spring 10. Cutter 6 is made in the form of a two-shouldered lever, one shoulder 11 of which, with its end face 12, interacts with the cartridge belt 2, and with the profile surface 13 interacts with the feed lever 1 when moving it, the other shoulder 14 interacts with the cover 4. The cartridge feed mechanism new includes a puller 15, on which the profile surface 16 is made.

At the beginning of the feed, the feed lever 1 is located under the cutter 6 and squeezes it up. When applying, the feed lever 1 pushes the cartridge belt 2 with the feeder 3, while the limiter 9, folding, jumps over the next link of the cartridge belt 2 and under the action of the spring 10 rises to its original position. As the feed lever 1 moves forward in the feed direction, the next cartridge, sliding along the profile surface 16 of the puller 15, decreases from the link, and the cutter 6 falls under the action of its spring 7 and at the end of the feed rises to a position that prevents the inertial run of the cartridge strip over the line lowering - duplication, and holds the released link in a position that does not interfere with the lowering of the reduced cartridge into the barrel.

When the feed lever 1 moves backward, the stopper 9 holds the cartridge belt 2 in place, the feeder 3 folds and jumps over the released link of the cartridge belt 2. The feed lever 1 pushes the cutter 6 up and out of the interaction with the cartridge belt 2, providing the next cartridge.

The proposed design of a feed mechanism for automatic weapons with tape power allows you to increase the reliability of the feed mechanism due to the complete elimination of the inertial movement of the cartridge belt inside the weapon when feeding the cartridge belt.
