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 known T-72 tank [1], a disk-shaped conveyor is placed on the floor and contains double cassettes arranged horizontally one above the other in the direction to the center of the circle. Separate loading shots of the same length are located in the cassettes: at the top there is a projectile charge, at the bottom there is a projectile, part of them containing guided shells, and the other part of them are unguided shells. In the aft part of the BO there is a loading mechanism, consisting of a mechanism for withdrawing (raising) a shot to the sending line and a mechanism for sending the shot to the barrel.

 The disadvantage of this design is the impossibility of automatically loading unitary artillery rounds having different (large) lengths.

 The well-known infantry fighting vehicle BMP-3 [2] is armed with 100 mm rounds of various lengths: a short one with a high-explosive fragmentation shell and a long one 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 longer loading time of shots with a guided projectile due to the manual operation.

 The known device for storing ammunition of various types and automatic loading of a tank gun has a clip mounted on the aft of the tower, containing a stock of shells. The clip consists of at least two 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. [3].

 The disadvantage is the use of protective containers with fasteners that must be removed from the fighting compartment, which distracts the crew from performing the combat mission.

 The objective of the alleged invention is to create a design of the loading mechanism, providing semi-automatic loading of unitary shots of different lengths, reducing the loading time of shots and increasing the combat effectiveness of the crew of the fighting compartment.

 The problem is solved in that the loading mechanism of the rotating conveyor, which feeds the shots to the loading mechanism of a large-caliber gun - a launcher located in the infantry fighting vehicle, contains a clip and a stepping mechanism. The clip is made in the form of a movable platform moving on rollers between two racks. At the bottom of the clip has a support for shots mounted vertically. Shots are fixed by spring-loaded latches placed between two adjacent shots and pivotally connected to the platform. On a stand opposite from the platform, spring-loaded dogs abutting against the shot are articulated. At the top of the rack is a spring-loaded lever that interacts with the carriage copier. In the lower part there are wedges interacting with the latches of the platform. The platform drive is made in the form of a lever with a handle pivotally mounted on a rack and connected by a rod with a two-arm lever. One end of the two-shouldered lever is pivotally mounted on the rack, and a roller is installed at the other end, which interacts with the counter groove of the rack and the vertical groove of the carriage.

 The proposed solution is illustrated in the graphic materials, where in FIG. 1 shows a loading mechanism with a rotating conveyor; FIG. 2 is a view of the loading mechanism from the drive side, in FIG. 3 is a top view of the loading mechanism, in FIG. 4 is a view of the loading mechanism from the side opposite to the drive, in FIG. 5 is a view of the end loading mechanism.

 The loading mechanism 1 is located inside the rotating conveyor 2 and consists of a movable platform 3 (Fig. 5), mounted using the rollers 4 on the rack 5 (Fig. 4). The platform 3 is a welded structure, equipped with a support 6, on which the shots 7 are mounted. From tipping, the shots 7 are held by a stop 8 (Fig. 3) and spring-loaded latches 9, 10, 11 (Fig. 4) located on the platform 3.

 The manual drive of the platform is placed on the rack 5 and consists of a lever 12 (Fig. 2) with a handle 13 and a two shoulders lever 14 with a roller 15 (Fig. 4), pivotally connected by a rod 16 (Fig. 3).

 In the lower part of the rack 5, wedges 17 are pivotally mounted (Fig. 4), and in the upper part there is a lever 18 interacting with the copier 19 of the platform 3. On the opposite to the platform of the rack, spring-loaded dogs 20 are pivotally fixed (Fig. 3).

 The loading mechanism works as follows. In the initial position, shots 7 are fixed in the platform 3 by latches 9, 10, 11. The platform 3 relative to the rack 5 is fixed using a spring-loaded handle 13.

 When the lever 12 is rotated along the arrow “a”, the two-arm lever 14 is rotated accordingly, the roller 15 interacts with the grooves of the rack 5 and platform 3, while the platform 3 moves toward the conveyor 2. When the platform 3 moves with shots 7, the wedges 9, 10 squeeze the wedges 17 , and the latch 11 at the end of the stroke interacts with the bevel of the conveyor 2, while the extreme shot 7 is unlocked in the platform and fixed in the cell of the conveyor 2. Dogs 20 and lever 18 do not interfere with the movement of the platform.

 When the platform 3 moves backward, the latch 11 bends around the shot fixed in the conveyor 2, and the shots remaining in the platform move with it all the way to the dogs 20. The lever 18 interacts with the copier 19, while the lever 19 forcibly tracks the trajectory of the last of the shots remaining in the carriage. . By the time the shots are touched with the dogs 20, the wedges 17 squeeze the latches 9, 10, and the latch 11 under the action of the spring again becomes in working position. With further movement of the platform to the initial position, the latches 9, 10 round the shots and, under the action of their springs, become in a fixed position. In this case, the shots remaining in the platform are shifted relative to the platform by one step in the direction of the conveyor cell.

 Thus, the proposed solution made it possible to provide semi-automatic loading of unitary shots of different lengths, reduce the loading time of shots and increase the combat effectiveness of the crew of the fighting compartment.
