Description

Technical Field

[0001] This utility model relates to the field of ammunition supply technology, and in particular to a pneumatic projectile pushing device. Background Technology

[0002] In fields such as artillery loading, rapid transfer of ammunition depots, and continuous ammunition supply for automated weapon systems, traditional ammunition supply methods mainly employ two structural forms: mechanical transmission and hydraulic drive. Due to their precise and complex structure, mechanical transmission devices are prone to gear wear and connecting rod loosening in harsh environments such as high temperatures, dust, and humidity, leading to decreased transmission accuracy and frequent malfunctions such as ammunition jamming and supply interruptions, which seriously affect the continuous combat capability of weapon systems. Hydraulic drive devices are prone to pipeline leaks, and the viscosity of hydraulic oil changes greatly with temperature. In extremely cold or hot environments, the ammunition supply efficiency is greatly reduced, and they may even fail to function properly.

[0003] Furthermore, both mechanical and hydraulic systems are structurally inefficient at simultaneously supplying multiple rounds of ammunition, typically only one round at a time. Under the demands of high-intensity combat, this feeding efficiency falls far short of the weapon's rate of fire requirements. Therefore, traditional ammunition feeding methods suffer from drawbacks such as complex structure, low efficiency, and inconvenient operation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a pneumatic projectile feeding device, which solves the technical problems of complex structure, low efficiency, and inconvenient operation in traditional projectile feeding methods.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A pneumatic projectile feeding device uses air pressure to move the projectile and achieve the projectile feeding action. Before operation, the air compressor compresses the rated air pressure to the air tank and clamping / unlocking pneumatic circuit. During operation, the ultra-thin cylinder first unlocks the OK clamp at the tail of the projectile, and then the manual ball valve of the projectile feeding air circuit is operated to allow compressed air to flow from the air tank through the air distributor to the rear end of the projectile feeding cylinder and push the projectile to slide. The projectile slides to the receiving box and stops under the buffering effect of the buffer nylon flare at the head of the receiving cylinder. At the same time, the locking clip on the receiving cylinder locks the projectile to prevent it from moving backward.

[0007] The pneumatic projectile pushing device includes a test bench, a projectile feeding box, a projectile receiving box, and a pneumatic circuit.

[0008] Furthermore, the test bench adopts a linear optical axis guide rail and a locking slider design with a strong lock. Four sets of locking sliders with side locking are inserted into the linear optical axis guide rail. The lower clamps of the feed box and the receiving box are fixed to the locking sliders with screws. By adjusting the position of the locking sliders on the guide rail, the position between the feed box and the receiving box can be adjusted and locked.

[0009] Furthermore, the five ammunition feeding cylinders in the ammunition feeding box have two grooves on the front and rear of their outer rings, which are respectively fitted with two sets of upper and lower clamps in semi-circular arc. The sides of the clamps are fixed to the bosses, and the lower clamps are fixedly connected to the locking slider. The rear cover is fixedly connected to the upper and lower clamp studs. The air passage is sealed by pressing the end face of the ammunition feeding cylinder onto the sealing ring of the rear cover. A rubber sealing gasket is installed between the ultra-thin cylinder that clamps the pneumatic pipeline SDA and the rear cover. The fixing screw holes of the ultra-thin cylinder are designed as blind holes to enhance the sealing effect.

[0010] Furthermore, the five receiving cylinders in the receiving box have two grooves on the front and rear of their outer rings, which are fitted with two sets of upper and lower clamps in a semi-circular arc. The sides of the clamps are fixed to the bosses, and the lower clamps are fixedly connected to the locking slider. The tail end of the receiving cylinder has a flared opening to facilitate the movement of the bullet from the feeding cylinder to the receiving cylinder. The front end is designed with a hole diameter smaller than the cylindrical outer diameter of the cushioning nylon to position and restrict its forward movement. The outer ring of the cushioning nylon is cylindrical, with a conical flared opening inside. The outer ring is fixed to the end face of the front wall of the receiving cylinder. A threaded hole is opened on the receiving cylinder to install a locking mechanism. The locking mechanism is spring-loaded and rotates to reset. The bullet head and bullet body boss slide past the locking mechanism, and the locking pin extends to lock the boss on the bullet, fixing the bullet axially. When the locking mechanism is manually rotated, the locking pin retracts, and the bullet can move axially.

[0011] Furthermore, the pneumatic circuit is divided into a projectile feeding pneumatic circuit and a clamping / unlocking pneumatic circuit. The projectile feeding pneumatic circuit provides power for projectile feeding, while the clamping / unlocking pneumatic circuit ensures projectile fixation and unlocking. An air compressor compresses rated air pressure to the air tank and the clamping / unlocking pneumatic circuit. The clamping / unlocking pneumatic circuit is divided into two paths by a three-position five-way valve to five ultra-thin cylinders. One path of air pressure in the ultra-thin cylinders clamps the OK clip, while the other path unlocks it, achieving both the locking function for the projectile tail and the reliable unlocking function. In the projectile feeding pneumatic circuit, compressed gas from the air tank passes through a manual ball valve and is then divided into five paths by an air distributor to the rear end of the projectile feeding cylinder, pushing the projectile to slide.

[0012] This pneumatic projectile pushing device uses compressed air as its power source and achieves stable ammunition delivery through an optimized pneumatic cylinder and a precision air circuit control system. Its structure eliminates many complex mechanical parts and hydraulic lines, resulting in a simple and compact overall design that reduces the failure rate and significantly lowers maintenance difficulty. In terms of efficiency, the device can simultaneously push multiple rounds of ammunition as needed, significantly improving ammunition delivery efficiency and ensuring the efficient operation of equipment in fields such as artillery loading, rapid ammunition depot transfer, and continuous ammunition supply for automated weapon systems.

[0013] By employing the above technical solution, this utility model provides a pneumatic projectile pushing device, which has at least the following beneficial effects:

[0014] 1. The pneumatic projectile feeding device provided by this utility model has the advantages of simple structure, detachable, convenient installation, easy operation, high efficiency and wide application. It can realize the simultaneous feeding of multiple projectiles, thereby meeting market demand and is suitable for promotion.

[0015] 2. The pneumatic projectile pushing device provided by this utility model uses air pressure to push the projectile to move and realize the projectile feeding action. It can simultaneously feed 5 projectiles. It has a compact and simple structure, is easy to install, easy to operate, and operates quickly.

[0016] 3. The pneumatic projectile pushing device provided by this utility model innovatively designs a parallel multi-channel pneumatic pushing structure, which can realize the simultaneous pushing of multiple munitions with high efficiency. It adopts a modular design, and the components are connected through standardized interfaces. When a component fails, the operator can quickly replace the damaged module without the need for complicated tools, simply by plugging and unplugging. Attached Figure Description

[0037] like Figure 4 and 5As shown, the ammunition feeding box 2 consists of an ammunition feeding cylinder 21, a first clamp 22 composed of an upper clamp and a lower clamp, a rear cover 23, a sealing ring 24, and a sealing gasket 25.

[0038] like Figure 6 and 7 As shown, the ammunition receiving box 3 consists of an ammunition receiving cylinder 31, a second clamp 32 composed of an upper clamp and a lower clamp, a buffer nylon 33, and a locking mechanism 34.

The ammunition receiving cylinder 31 has a flared opening at its tail end, and the front end has a hole diameter smaller than the cylindrical outer diameter of the buffer nylon 33, which is used to position and restrict the forward movement of the buffer nylon 33. The outer ring of the buffer nylon 33 is cylindrical, and the inside is designed as a conical flared opening. The outer ring is glued and fixed to the front wall and end face of the ammunition receiving cylinder 31.

[0039] like Figure 8 , Figure 9 and 10 As shown, the pneumatic circuit 4 consists of a feed air path 41 and a clamping / unlocking pneumatic circuit 42.
