Detailed Description
Referring to fig. 1-5, in order to illustrate an embodiment of the present invention, the emitting direction is defined as the front.
The two-shaft ammunition feeder is characterized in that a front cover component 1, an ammunition feeder frame component 2 and a gear box component 4 are used as a supporting structure, and the rest parts and components are assembled into a whole through the three components. The first transmission shaft mechanism consists of a chain-off gear shaft 13, a bullet-pushing groove 5 and a bullet-guiding wheel 6, and 7 bullet-containing grooves are uniformly arranged in the circumferential direction of the shaft; the second transmission shaft mechanism consists of a first bullet poking wheel shaft 10, a bullet poking wheel 8 and a second bullet poking wheel shaft 9, and 6 bullet containing grooves are uniformly arranged in the circumferential direction of the shaft.
The working principle is as follows: the gear box component 4 is meshed with a transmission gear on a rotating pipe machine gun to provide power for the bullet feeder; the gear box component is matched with an elastic feeding gear and an input gear 18 through an internal chain-off gear 16 and an idle gear 17, so that the chain-off gear shaft 13 and the first elastic-poking wheel shaft 10 output according to a fixed rotating speed ratio of 6: 7. The chain-off gear shaft 13 is a power shaft of the first transmission shaft mechanism, and the first poking elastic wheel shaft 10 is a power shaft of the second transmission shaft mechanism. The first transmission shaft mechanism achieves the functions of pulling the bullet chain, longitudinally releasing the chain and throwing the chain, under the action of the rear guide block 7, bullets are conveyed to the bullet poking wheel 8 of the second transmission shaft mechanism, and the bullet poking wheel 8 is driven by the second transmission shaft mechanism to convey ammunition to a specified position.
Pulling the elastic chain belt: the bullet inlet channel consists of a bullet inlet interface 14, a bullet pressing cover part 11, bullet blocking teeth 15, a bullet pushing groove 5 and a missile wheel 6. When the first bullet is hung, the bullet chain belt passes through the bullet inlet interface 14, the first bullet is placed on the bullet pushing groove 5 and the bullet guide wheel 6, and at the moment, the bullet chain belt is hung by the bullet stopping teeth 15, so that the bullet chain can move forward and cannot move backward. When shooting operation is carried out, the bullet pushing groove 5 and the missile wheel 6 rotate clockwise under the driving of the chain-off gear shaft 13, the bullet chain belt is driven to rotate clockwise to realize the pulling of the bullet chain, and at the moment, the bullets and the bullet chain are subjected to space constraint by the bullet pushing groove 5, the missile wheel 6 and the bullet pressing cover component 11.
Longitudinal chain removal: 7 ejector rod parts 3 are arranged in the ejector slot 5, and each ejector rod part 3 corresponds to one projectile. Under the action of the ammunition feeding curve groove 19, the ejector rod part 3 reciprocates back and forth. The bullet chain is blocked by the missile wheel 6 and can not move forwards, and is blocked by the missile pushing groove 5 and can not move backwards. When the chain releasing gear shaft 13 rotates clockwise, the elastic pushing rod component 3 moves forwards, the pushing elastic moves forwards, and longitudinal chain releasing is completed.
Chain throwing: when the bullet completely breaks away from the bullet chain, the bullet chain forms space restriction by the bullet pushing groove 5, the missile wheel 6 and the bullet supply case 12. Under the drive of the chain-removing gear shaft 13, the elastic pushing rod part 3 moves backwards, the elastic pushing rod part 3 is separated from the elastic chain and continues to rotate, and the elastic chain is thrown out from the chain-throwing port 20 to finish chain throwing.
And (3) conveying of ammunition: after the bullets are completely separated from the bullet chain, the missile wheels 6 rotate clockwise under the action of the rear guide block 7, the bullets are conveyed to the bullet poking wheels 8 of the second transmission shaft mechanism from the first main shaft, at the moment, the bullets move in a channel formed by the bullet poking wheels 8, the bullet supply chassis 12 and the rear guide block 7, and when the second bullet poking wheel shaft 9 of the gear box component 4 continues to rotate, the bullet poking wheels 8 continue to rotate clockwise, and the bullets are conveyed to a fixed position.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims.
