Description

Technical Field

[0001] The utility model relates to the technical field of weapon stations, in particular to a double-layer ammunition box feeding mechanism and an ammunition box hanging rack structure. Background Art

[0002] With the continuous emergence of unmanned platforms, the 12.7mm anti-aircraft machine guns traditionally mounted on armored vehicles such as tanks, armored vehicles, and self-propelled artillery can no longer meet the platform's combat needs. Therefore, there is an urgent need to use a top-mounted remote-controlled weapon station that is highly versatile, has good passability, and is safe and reliable.

[0003] This type of remote-controlled weapon station usually requires a large amount of ammunition, and the original 60-round ammunition box for the vehicle-mounted machine gun can no longer meet the use requirements, so the use of large-capacity ammunition boxes and feeding mechanisms came into being. The large-capacity ammunition box itself weighs a lot when fully loaded, about 38kg. If the ammunition box is directly installed on the swing frame and pitches with the elevation mechanism, it will greatly increase the elevation servo load and generate a large unbalanced torque. The stability of the dynamic shooting of the weapon station is not easy to guarantee, so the ammunition box must be fixed on the azimuth rotary bracket. The weapon station adopts a top-mounted installation method. The distance between the ammunition box and the machine gun feed port is far, and the ammunition box is arranged parallel to the line of fire. The ammunition feeding route needs to be turned before feeding can be realized. The feeding resistance is large, and it is easy to stop firing and other faults.

[0004] Due to the large size difference between the front and rear ends of the 12.7mm bullet, after the bullets are arranged in a "Z" shape in the magazine, the bullet tips are tilted at a large angle. At the fifth layer, the bullets are basically in a vertical state, that is, the bullet tips are facing downward, intersecting with the bullet tips of the rows of bullets below, increasing the resistance to bullet feeding and easily causing problems with insufficient bullet feeding force.

[0034] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0035] Example: See Figure 1 — Figure 7 .

[0036] The ammunition box 1 of the weapon station is installed in the inner cavity of the ammunition box bracket body 12, and the ammunition box limit block 11 is pressed and limited by the front limit block 13 and the bracket locking plate 16, the bracket locking plate 16 is closed, the locking shaft 15 is pressed downward to the bottom, and is locked by the upper limit pin of the bracket seat 14, the limited installation of the ammunition box 1 is completed, the locking shaft 15 is lifted to the upper limit position, the bracket locking plate 16 is opened counterclockwise, and the handle 10 is grabbed by hand and pulled outward to remove the ammunition box 1; the ammunition box bracket 5 is fixedly installed on the bracket 4 by 8 M10 bolts and washers 29, so that the ammunition box 1 rotates with the bracket 4 in azimuth (rotation in the horizontal plane, the bracket 4 is connected to the weapon station); first, the coaxial seat 18 is inserted into the left ear shaft 28, and then the connecting seat 20 is pressed by 4 M5 screws and washers 27, and the hard guide 2 is fixed to the cradle 3, and pitches with it in the height direction.

[0037] Arrange the bullets loaded into the ammunition belt in the shape of a "Z" in the ammunition box 1, with one end of the bullet tip placed on the bottom plate ammunition box pad 26 and the angled end of the middle partition 23 facing upward, and first install the middle partition 23 and flip it upward to the highest point around the partition hinge 24. After filling the second compartment 25, then install the first compartment 22 until the bullets are loaded, and then cover the ammunition box cover 8, press the ammunition box lock 9, and complete the loading of the ammunition box; pull the bullets out of the ammunition box body 6 along the middle position of the two rollers 7, load them into the feed port of the hard guide 2, drag them out of the feed channel 19 along the ratchet mechanism 17 and the bullet wheel 21, open the ammunition feed cover, and hang the first round of ammunition on the gun body, close the ammunition feed, and complete the loading of the weapon station. When the weapon station is turned in height, the ammunition box 1 is fixed, the hard guide 2 pitches with the cradle 3, and the bullets rotate around the ear axis in the hard guide 2 to realize the feeding during the turning process.

[0038] The bullet outlet of the ammunition box is located in the middle of the ammunition box, shortening the ammunition feeding route in the ammunition box; the ammunition box adopts an upper and lower double-layer structure to meet the 200-round ammunition load requirement; one end of the hard guide is installed on the swing frame and the ear axis, and when the weapon station rotates vertically, the hard guide bullet inlet rotates around the ear axis.

[0039] An angled bottom plate and a middle partition are provided in the ammunition box. When the bullets are arranged in the ammunition box, the bullet heads of the bottom part are raised at a certain angle and the bottoms of the bullets face downward. When the bullets are full, they are basically in a horizontal state, which solves the shooting failure caused by the tilt of the bullets. The ammunition box adopts a double-layer structure. When shooting, the rear compartment starts to feed bullets only after the bullets in the upper compartment of the ammunition box are fired. The feeding route in the ammunition box is relatively short. At the same time, a roller structure is provided at the bullet outlet position of the ammunition box. When feeding, the bullets are fed along the roller position, which reduces the feeding resistance and makes the feeding route reasonable and controllable.

[0040] The hard guide consists of a feed channel, a connecting seat, a coaxial seat, a ratchet mechanism and a magazine wheel. The feed channel is designed to match the flexibility of the 12.7mm ammunition chain and is welded from sheet metal with a smooth surface and low resistance. The hard guide has a ratchet mechanism at the bullet introduction position, and the bullet moves in one direction, reducing the resistance generated by the bullet itself during feeding. The coaxial seat moves coaxially with the ear shaft and rotates with the height of the swing frame, ensuring the reliability of feeding.
