Description

Technical Field

[0001] This invention relates to the field of automatic rocket feeding technology, specifically a box-type automatic feeding mechanism. Background Technology

[0002] Rockets are munitions propelled by rocket engines. They are primarily used to kill or suppress enemy personnel, and to destroy fortifications and weaponry. Based on their flight stabilization method, they are classified into fin-tailed rockets and turbine-powered rockets.

[0003] After a box of rockets is launched, there is no automatic ammunition supply mechanism to replenish the ammunition. The entire ammunition box needs to be hoisted and replaced. However, in the rod-type ejection launch method, the ammunition box contains the ejection rod, firing mechanism, etc. Replacing the ammunition box is costly and inefficient. Therefore, a new type of box-type automatic ammunition replenishment mechanism needs to be designed.

[0004] Therefore, we propose a box-type automatic ammunition feeding mechanism to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a box-type automatic ammunition feeding mechanism that is compact in structure, easy to operate, and has a strong loading capacity. It can realize the automatic feeding of ammunition boxes, meet market demand, and is suitable for promotion, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a box-type automatic ammunition feeding mechanism, comprising an ammunition loading box and a fixed chassis installed at the lower end of the ammunition loading box; A feeding frame is installed in the middle of the fixed chassis, and the loading box is disposed in the feeding frame. Two racks are installed at the lower end of the loading box. A guide rail is installed at the upper end of the fixed chassis. The spacing of the guide rail is consistent with the spacing of the two racks at the lower end of the loading box, and six racks are installed circumferentially. The racks are slidably mounted on one side of the guide rail. An electric push rod is installed at the lower end of the fixed chassis. The extension rod of the electric push rod is disposed at the lower end of the feeding frame. A firing system is connected to the upper end of the feeding frame. A firing box is installed at the upper end of the firing system. The electric push rod is used to push the bullet into the firing box. A locking device is installed on the inner ring of the fixed chassis.

[0007] Preferably, a limit switch is fixedly installed at one end of the rack, the limit switch is installed on the upper end of the fixed chassis, and a collision protection block is also installed on the upper end of the fixed chassis. The limit switch and the collision protection block limit the movement of the ammunition box to the outermost side of the fixed chassis, and the fixed chassis is fixedly installed on the combat system platform.

[0008] Preferably, a drive structure is installed at the lower end of the fixed chassis, and multiple drive structures are provided, with each drive structure hanging below the lower end of the ammunition box.

[0009] Preferably, the ammunition box is a square box structure, which contains twenty rounds of ammunition. The lower end of the ammunition box is fixedly connected to the rack and pinion, and the ammunition feed rack is a square basket structure.

[0010] Preferably, a rotating shaft is installed inside the ammunition feed rack, and a first baffle is rotatably mounted on one end of the rotating shaft.

Through the coordination of mechanisms such as the ammunition feed rack, ammunition box, fixed chassis, electric push rod, guide rail, rack, transmission system, motor, anti-collision block, limit switch, and locking mechanism, during ammunition feeding, the firing system and firing box rotate vertically downwards under the action of the elevation mechanism and lock. The ammunition feed rack, depending on the ammunition type, rotates horizontally circumferentially under the drive of the azimuth mechanism to align with one of the six ammunition boxes (six square ammunition boxes are used to load different types of ammunition as needed) and locks. The drive mechanism then drives the rack to push the ammunition box into the ammunition feed rack. The ammunition is vertically aligned and locked with the launch box's ammunition magazine. The ammunition-fixing device in the loading box is unlocked, and the vertical electric push rod extends to feed the ammunition.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-5 The present invention provides a technical solution: a box-type automatic ammunition feeding mechanism, including an ammunition box 1 and a fixed base 9 installed at the lower end of the ammunition box 1. The fixed base 9 is in the shape of a flat ring and serves as the mounting base for the ammunition feeding mechanism. An ammunition feeding frame 7 is installed in the middle of the fixed base 9. The ammunition box 1 is placed in the ammunition feeding frame 7. Two racks 2 are installed at the lower end of the ammunition box 1. A guide rail 4 is installed at the upper end of the fixed base 9. The spacing of the guide rail 4 is consistent with the spacing of the two racks 2 at the lower end of the ammunition box 1, and six racks 4 are installed circumferentially. The racks 2 are slidably installed on one side of the guide rail 4.

[0019] A limit switch 3 is fixedly installed at one end of the rack 2. The limit switch 3 is installed on the upper end of the fixed chassis 9. A crash block 8 is also installed on the upper end of the fixed chassis 9. The limit switch 3 and the crash block 8 limit the movement of the ammunition box 1 to the outermost side of the fixed chassis 9. The fixed chassis 9 is fixedly installed on the combat system platform.

[0020] A drive structure 5 is installed at the lower end of the fixed chassis 9. Multiple drive structures 5 are respectively hung at the lower end of the loading box 1 to provide a power source for the movement of the loading box 1. The drive structure 5 includes a motor, a belt and a gear. The gear meshes with the rack 2. After the motor starts, the gear rotates and the rack 2 moves on the guide rail 4, which facilitates the movement of the loading box 1 into the ammunition supply rack 7.

[0021] The ammunition box 1 is a square box structure, which contains twenty rounds of ammunition. The lower end of the ammunition box 1 is fixedly connected to the rack 2. The ammunition feed rack 7 is a square basket structure. An electric push rod 6 is installed at the lower end of the fixed chassis 9. The extension rod of the electric push rod 6 is located at the lower end of the ammunition feed rack 7. The upper end of the ammunition feed rack 7 is connected to the firing system 10. A firing box 11 is installed at the upper end of the firing system 10. The electric push rod 6 is used to push the ammunition into the firing box 11. A locking lock 12 is installed on the inner ring of the fixed chassis 9. The locking lock 12 locks the ammunition feed rack 7 on both sides after it rotates and aligns with the ammunition box 1, which facilitates the stability of ammunition feeding.

[0022] Each extension rod of the electric push rod 6 is coaxial with the ammunition box 1 and the launch box 11 after the ammunition feed rack 7 moves into place, vertically pushing the ammunition from the ammunition box 1 to the launch box 11. The launch system 10 is fixed to the combat system platform by a rotating seat, and the launch box 11 is mounted on the launch system 10 by a high and low trunnion. The electric push rod 6 pushes the ammunition in the ammunition box 1 to the launch box 11. The bottom of the ammunition is fixed to the launch box 11, and the vertical ammunition feeding is completed. The telescopic rod of the electric push rod 6 is retracted, and the launch box 11 adjusts its angle according to combat requirements for combat firing.

[0023] The ammunition feed rack 7 has a rotating shaft 22 installed inside. A first baffle 13 is rotatably installed at one end of the rotating shaft 22. The first baffle 13 is elastically connected to the inner wall of the ammunition feed rack 7 through a first elastic element 18. A limit block 23 is fixedly installed on the inner wall of the ammunition feed rack 7. A second baffle 19 is also rotatably installed on the rotating shaft 22. The second baffle 19 is fixedly connected to the first baffle 13.

[0024] A groove 14 is provided on the first baffle 13, and a first contact piece 17 is fixedly installed on one side of the groove 14.

[0025] The rotating shaft 22 is also rotatably mounted with a third baffle 15. The third baffle 15 is rotatably mounted on the upper end of the first baffle 13. The lower end of the third baffle 15 is rotatably mounted with a second contact piece 16. The second contact piece 16 is slidably mounted in the slide groove 14. One end of the second contact piece 16 is also elastically connected to the inner wall of the slide groove 14 through a second elastic member 21.

[0026] A third contact piece 20 is fixedly installed on the second baffle 19.

[0027] When the ammunition box 1 moves into the ammunition rack 7, one end of the ammunition box 1 abuts against the third baffle 15. The second contact piece 16 at the lower end of the third baffle 15 pulls up the second elastic element 21 and makes contact with the first contact piece 17. The two contacts are electrically connected, triggering an alert. At this time, the third baffle 15 and the first baffle 13 are nearly overlapped. The ammunition box 1 continues to be pushed forward. The first baffle 13 and the second baffle 19 rotate 90 degrees and lock into one corner of the ammunition box 1. The first elastic element 18 is compressed until the third contact piece 20 of the second baffle 19 abuts against the ammunition box 1. The contact piece is a conductive structure, triggering an alert a second time. After the two alerts, it can not only play a limiting role, but also ensure that the ammunition box 1 moves into place and completes docking with the electric push rod 6, which facilitates the pushing of the electric push rod 6.

[0028] Working principle: The fixed chassis 9 serves as the mounting base for the ammunition feeding mechanism; the ammunition box 1 is equipped with a 20-round magazine that can store 20 rounds of ammunition, and a rack 2 is installed at the lower end, allowing it to slide horizontally on the fixed chassis 9 and the ammunition feed rack 7. Six ammunition boxes 1 are evenly distributed around the fixed chassis 9, capable of loading different types of ammunition, totaling 120 rounds; anti-collision blocks 8 and limit switches 3 are installed on the side of the ammunition feed rack 7 and on the fixed chassis 9, providing movement limits for the ammunition boxes 1; the drive structure 5, composed of a motor and transmission components, provides the power source for the movement of the ammunition boxes 1, with one set for each ammunition box 1, which loads the ammunition on the fixed chassis 9... The ammunition box 1 is moved to the ammunition feed rack 7, or after the ammunition is fed, the empty ammunition box 1 is moved back to the fixed chassis 9; the electric push rod 6 is installed at the lower end of the ammunition feed rack 7. After the ammunition box 1 is moved into place on the ammunition feed rack 7, the ammunition is pushed vertically from the ammunition box 1 to the launch box 11; the locking 12 locks the ammunition feed rack 7 on both sides after it rotates and aligns with the ammunition box 1, which facilitates the stability of the ammunition feeding; the ammunition feed rack 7 is a basket-type design. The upper part is fixed to the launch system 10 and rotates circumferentially with the launch system 10 and the launch box 11 to maintain the same direction. The bottom upper surface is equipped with a guide rail 4 to facilitate the movement of the ammunition box 1.

[0029] During ammunition feeding, the firing system 10 and firing box 11 rotate vertically downwards under the action of the elevation mechanism and lock. The ammunition feeding rack 7 rotates horizontally around the circumference under the action of the azimuth mechanism according to the ammunition type and aligns with one of the six ammunition loading boxes 1 (the six square ammunition loading boxes 1 are loaded with different types of ammunition as needed) and locks. The drive structure 5 drives the rack 2 to push the ammunition loading box 1 into the ammunition feeding rack 7. After it is in place, it is vertically aligned with the ammunition tube of the firing box 11 and locked. The ammunition fixing device in the ammunition loading box 1 is unlocked. The vertical electric push rod 6 extends and pushes the ammunition to feed the ammunition. After the ammunition is in place and fixed in the firing box 11, the vertical ammunition feeding is completed. The electric push rod 6 extends and retracts, unlocking the gun. The drive structure 5 drives the rack 2 to push the ammunition loading box 1 in the ammunition feeding rack 7 back to the fixed chassis 9. The firing box 11 rotates at the angle according to the firing mission. This cycle is repeated to achieve fixed-angle loading.
