Description

 The invention relates to military equipment, and more specifically to automated storage and supply of ammunition in armored vehicles, ship installations and lightly armored infantry fighting vehicles.

 In the well-known infantry fighting vehicle BMP-3 [1], the armament has 100 mm rounds of carved length: short with a high-explosive fragmentation shell and long with a guided projectile. In this case, a shot with a guided projectile has a length of about two times more than a high-explosive fragmentation shot and is manually charged.

 The design drawback is the large loading time of shots with a guided projectile due to the execution of this operation manually.

 A known device for storing ammunition of various types and automatic loading of a tank gun [2] has a clip mounted on the aft of the tower, containing a stock of shells. The clip consists of at least 2 independent stores, each of which contains a certain number of shells and a separate step mechanism for feeding shells. In each store, the shells are located in separate ejected protective containers having fasteners for temporarily connecting the containers to each other and the entire container system with an appropriate feed mechanism.

 The disadvantage is the use of protective containers with fasteners, which must be removed from the fighting compartment, which has limited dimensions.

 The objective of the invention is to create the design of the device for supplying shots of an gun mount, which provides automatic loading of unitary shots of different lengths, increasing the number of shots delivered and reducing the time of supply of shots to the gun.

 The problem is solved in that in the known device for supplying shots of an gun mount containing a magazine and a stepping mechanism, the magazine is made in the form of a movable platform with latches, guides and a hook. The stepping mechanism consists of a rack mounted in the platform rails. Rollers and an earring interacting with the hook are pivotally mounted on the rail. On the axes of the latches are fixed levers interacting with the rollers of the rack, which is kinematically connected with the drive.

 The teeth of the rack are coupled to the lower gear of the drive, consisting of an electric motor and gearbox. Coaxially to the lower gear, a spring-loaded upper gear is mounted on the pins, mounted with the possibility of interaction with the movable gear of the manual drive. On the conical surfaces of the upper and lower gears, an asterisk is installed in contact with the rail.

 The invention is illustrated by drawings, where figure 1 shows a device for supplying shots of a gun mount with a conveyor, top view; figure 2 is a view of the device from the neck; figure 3 is a transverse section; figure 4 shows the drive in the context.

 The gun supply system of the gun mount consists of a base 1 (FIG. 2), a movable platform 2, a drive 3 and a wall 4 (FIG. 1). In the upper part of the base 1, rollers 5 are installed (Fig. 4), along which the platform 2 moves, a spring-loaded lever 8 (Fig. 1) and an arm 9 (Fig. 2). Wedges 6 and a guide 7 are installed in the lower part of the base. With bolts 10, the base is attached to the floor of the fighting compartment of the gun mount.

 On the body of the platform 2, latches 11 and 12 are installed (Fig. 3), a gear rack 13 with an earring 14 and rollers 15 mounted on the axles 16, a hook 17 and a copier 22 (Fig. 1).

 The guide 23 (FIG. 4) serves to mount the platform 2 on the base 1 with the possibility of moving in the longitudinal direction along the rollers 5. The rollers 21 (FIG. 2) mounted on the support 18 (FIG. 3) interact with the guide 7 (FIG. 2) and hold the platform in the transverse direction.

 The drive 3 is attached to the base 2 and consists of an electric motor, gearbox and a manual feed drive.

 Wall 4 (figure 1) using the racks 33 and 34 (figure 2) is attached to the floor of the fighting compartment. Spring-loaded clips 29 (FIG. 3) and a guide 30 are mounted on it with the possibility of adjusting the gap between it and the shots mounted on the platform.

 The device operates as follows. In the initial position, the platform 2 and the rail 13 are displaced along the arrow "G" to the stop, the rollers 15 of the rail 13 act on the levers 19, which through the rods 36, 37 and the clamps 11, 12 press the shots to the stop 35, the retainer 29 and hold them in a fixed position position.

 Work from the electric drive is as follows. The rotation from the electric motor through the gearbox is transmitted to the pinion gear 27, and through the pins 26 to the pinion gear 25. The rack 13 moves against the arrow "G", while the rollers 15 release the levers 19, and therefore the latches 11, 12. The platform remains in place until moment until the earring 14 captures the backlog 17, rigidly connected with the body of the platform. The rack makes a free run, while the rack prevents the rotation of the sprocket 20, and the gears 25 and 27, compressed by the spring 24, rotate. Thus, the friction clutch is turned on and loads the electric motor with the rated torque until it is connected to the platform rail.

 Further movement of the rail goes in conjunction with the platform, which sends an extreme shot to the conveyor "E" slot, where it is fixed. At the same time, a command is sent to turn off the electric motor and its reverse, and therefore, return the platform to its original position.

 First, the platform moves together with the shots until the latter stops in the latches 29, and then the platform moves relative to the shots. In this case, the rods 36 of the clamps 11 interact with the wedges 6 and the clamps “run” for the shots. Subsequently, the roller of the earring 14 ceases to be controlled by the base 1, the earring disengages from the hook 17 and the rail makes free play all the way into the hook 17, while the rollers 15 of the rail 13, acting on the levers 19, fix shots on the platform. As a result, the shots are shifted relative to the platform towards the conveyor by one step. The device is ready to feed the next shot into the conveyor.

 The operation of the loading mechanism from the manual feed drive is as follows.

 The lever 32 is rotated to a vertical position, while the spring 24 ceases to compress the gears 25 and 27, i.e. the friction clutch is turned off. Press the handle 31 down to the stop and turn along the arrow "D". The handle is released, it rises up under the action of the spring and in this position it is returned to its original position. In this case, gear 28 rises up to contact with gear 25. When the handle 31 is rotated, gear 28 is rotated, engages with gear 25 and rotates it. Through the pins 26, the rotation is transmitted to the six 27, which moves the rail.

 Further, the operation of the mechanism is similar to that of an electric drive. The reverse-rotational movement of the handle 31 is carried out to the end of the extreme shot into the conveyor cell and fixing it in this malposition. Then the platform with the remaining shots is returned to its original position.

 Thus, the proposed solution made it possible to provide automatic supply of unitary shots of different lengths, increase the number of shots delivered and reduce the time of supply of shots to the gun.
