Description

Technical field

The utility model relates to military equipment, namely to an automatic feed system for tape-fed cannon-barrel mounts, and can be used for continuous firing with ammunition supply in automatic mode without the presence of a serviceman and reloading the tape.

Prior Art

A known power supply system for automatic weapons (patent RF 2406052, IPC F41A 9/57, published 12/10/2010), containing a guide neck, fixed at one end on the receiving window of the weapon, and the other - on the store with a cartridge belt. In this case, the guide neck is made of two telescopically connected parts, and the bending radius of the necks, at the points of their connection, coincides with the horizontal axis of rotation of the weapon. A disadvantage of the known power supply system for automatic weapons is the large overall dimensions, which makes it difficult to place the power system inside the weapon station.

Closest to the claimed technical solution is an automatic weapon power supply system containing a guide neck made of two parts: an upper movable, fixed on the weapon, and a lower fixed, fixed on the magazine with a cartridge belt (RF patent 2509972, IPC F41A 9/29, published 03/20/2014). At the same time, the upper movable part of the neck is bent in the form of a loop to ensure that the cartridge belt is directed parallel to the barrel axis with the cartridge noses outward. At the entrance to the weapon, the tape unfolds so that the cartridges turn their noses in the direction of fire.

A disadvantage of the known solution is the unreliability of the design, due to the fact that the guide has bends in a plane parallel to the cartridge belt to turn the tape. In this case, the bending radius has a value commensurate with the width of the tape. Cartridge tape has significant rigidity in the plane parallel to the stacking of cartridges. When moving the tape along the guide neck, it will slow down and jam on its side stops.

A variant of the formation of an endless tape is a technical solution (patent US 8763511, F41A 9/29, published on 07/01/2014), in accordance with which it is possible to connect the rear end of the tape tucked into the barreled weapon and the front end of the next tape located in the cartridge box.

The disadvantage of this solution is the need to manually perform the connection of the ends of the previous and subsequent tape, which requires the mandatory presence of a person.

Known power supply system for automatic weapons, containing a guide neck, fixed at one end on the receiving window of the weapon, and the other - on the store with a cartridge belt (RF patent 2513334, IPC F41A 9/54, published 20.04.2014). The end of the neck fixed on the weapon is bent in a plane parallel to the axis of the weapon barrel bore, rollers are installed at the inlet of the tape into the weapon, ensuring the supply of cartridges to the receiving window of the weapon, the other end of the neck is equipped with a limiter and is hinged to the magazine. The axis of the hinge coincides with the axis of rotation of the weapon. The end of the neck mounted on the magazine is made in the form of a movable carrier fixed on the guide and equipped with two rollers interacting with the cartridge belt.

The known solution has significant dimensions. The radius of rotation of the cartridge belt in its plane is determined by the distance between adjacent cartridges in the belt. Its small value determines a significant bending radius of the tape and, as a result, significant dimensions.

Known cartridge belt increased capacity (RF patent 2663774, IPC F42B 39/08, published 08/09/2018). Ammunition in the cartridge belt until its ends are connected are located on both sides of the belt, and on different sides of the belt the ammunition is directed in opposite directions. After connecting the ends, the cartridge belt becomes one-sided. Ammunition on the cartridge belt are located at a distance from each other, providing the twisting of the tape when connecting its ends. The cartridge belt is made flexible, long and small width to ensure its twisting and joining the ends.

This technical solution significantly complicates the design of the feeder and is not feasible without additional equipment - supporting guides. In addition, the solution is not applicable to standard barreled weapons, due to the fact that two cartridges located one above the other fall into it at the same time.

Utility Model Disclosure

The technical problem to be solved by the utility model is to increase the reliability of the operation of the power supply system for automatic barreled weapons.

The technical problem is solved by the fact that in a well-known solution containing a magazine, an ammunition belt, guide necks for it, mounted on a weapon and a magazine, bent in the form of a loop to ensure that the tape is directed parallel to the axis of the barrel, the guide necks are made with a working surface parallel to the axis of the barrel on all the way from the magazine to the weapon, they form a closed chain with the weapon and the magazine, and the tape is made endless. In addition, the store is equipped with a mechanism for loading the belt with ammunition.

Brief description of the figures of the drawings

The essence of the utility model is illustrated by an illustration.

Figure 1 is a schematic representation of the technical solution. An embodiment of the utility model

The power supply device for automatic barreled weapons 1 includes a magazine 2, an ammunition belt 3, guide necks: inlet 4 and outlet 5 (Fig. 1). Each of the guide necks 4 and 5 is fixed to the magazine 2 and the weapon 1, respectively. The guide neck 4 is fixed at the exit a from the magazine 2 at one end, and at the other b on the basis of the receiver of the barreled weapon 1. The guide neck 5 is connected at one end C to the base of the receiver barrel weapon 1 (from the side of the opposite supply of the ammunition belt 3), and the second at the entrance to the store 2 - d.

The completed connection of the guides 4 and 5 with the barreled weapon 1 and the magazine 2 creates a closed, continuous chain. At the same time, along its entire length, the position of the surfaces of the guides 4 and 5, coupled with the tape parallel to the axis of the barrel weapon 1, is maintained. The guides 4 and 5 are located in the form of a loop with turns made only in one plane. As a result, the tape for ammunition 3 (and, accordingly, ammunition), throughout its contact with the guides 4 and 5, is parallel to the axis of the barrel of the weapon 1. This eliminates the bending of the tape for ammunition 3 in the plane of the ammunition and, accordingly, their jamming in the guides 4 and 5 is excluded. Before installing tape 3, its ends are connected to each other, which translates it into a state without ends - i.e. endless. In addition, the absence of a bend in the plane of the tape 3 eliminates the need for guides with a large radius - the compactness of the installation is ensured.

Shop 2 is equipped with a mechanism for loading the tape with cartridges (not shown in Fig. 1). In addition, it is equipped with a lifting cover 6 connected to the magazine body 7 through a hinge 8.

Preparing the power supply for automatic barreled weapons for operation. A part of the ammunition belt 3, loaded with ammunition, is placed in the receiver of the weapon 1, superimposed on the guide 4, inserted into the magazine 2, through the exit a, carried out through the loading mechanism. The unloaded part is withdrawn from magazine 2 through d.

The second end of the tape for ammunition 3 without ammunition, withdrawn from the receiver, in the zone c is placed on the guide 5 and connected to the end of the tape, withdrawn from the magazine 2. The tape for ammunition 3 becomes closed into an endless one.

Ammunition is being loaded into magazine 2. To do this, the cover 6 rotates in the hinge 8 relative to the magazine body 7.

The device has small dimensions due to the fact that the radius of rotation of the tape in the guide necks can be small. In fact, the dimensions of the device are determined only by the capacity of the store 2. In this case, there is a dense, continuous packing of ammunition in it. After loading the ammunition, automatic power is provided to the weapon 1 without human intervention.

The power supply device for automatic barreled weapons is ready for operation.

The operation of the power supply device for automatic barreled weapons.

After a shot from a barrel weapon, the movement of the ammunition belt 3, closed into an endless one, from the store 2 to the barrel weapon 1 takes place by one link of the belt. In store 2, the ammunition is driven into the ammunition belt 3. At the same time, through d, the tape is inserted into one link.

The movement of the tape for ammunition 3 is carried out in a closed circuit without transitions through the elements with the possibility of braking or jamming. The tape for ammunition 3, due to the fact that the guide necks 4 and 5 are made with a working surface parallel to the axis of the barrel of the barreled weapon 1, has no bends in the plane of the tape throughout its entire length. As a result, the need to use side stops on the guides 4 and 5 and the possibility of the ammunition tape 3 getting stuck in them is eliminated. High reliability of the operation of the power supply device for automatic barreled weapons is ensured.
