Description

Technical Field

[0001] The invention belongs to the military field, and in particular relates to an automatic loading mechanism. Background Art

[0002] Electromagnetic Launch (EML) is a technology that uses electromagnetic energy to accelerate and launch projectiles in whole or in part. Devices that launch projectiles using EML technology are generally referred to as electromagnetic guns. Compared with traditional artillery, electromagnetic guns have the following advantages: electromagnetic guns use the work done by electromagnetic force as the launch energy, and will not produce strong shock waves and diffuse smoke, so they have good concealment; and electromagnetic guns can adjust and select appropriate energy to adjust the range of the projectile according to the nature and distance of the target, and are highly efficient; electromagnetic gun projectiles are small in size and light in weight, and have little air resistance during flight, so electromagnetic guns have good launch stability, high initial velocity, and long range; since the launch process of electromagnetic guns is entirely controlled by computers, and the warhead is equipped with laser guidance or other guidance devices, it has high shooting accuracy; at the same time, the launch cost is much lower than that of traditional artillery. Due to a series of unique advantages of electromagnetic guns, they show good development prospects, and countries are vigorously promoting the research of electromagnetic guns. Although electromagnetic catapult technology has many advantages and broad application prospects, as a new type of artillery shell ejection technology, there are still many key technologies that need to be solved in its practical application.

[0003] The high rate of fire and high power of electromagnetic guns make them better than traditional artillery. If they can be loaded automatically and quickly, the performance of electromagnetic guns will be even better. With the application of advanced technology in artillery equipment, it is a trend for artillery systems to realize automatic loading and precise strikes of artillery ammunition in a short period of time. The precise and rapid strike capability of artillery will also be greatly improved. At the same time, it also brings great challenges to artillery defense systems. In the future battlefield, if the enemy and us are engaged in a war and we cannot destroy the target at one time, the enemy may quickly detect our specific location and will be devastated by the enemy's counterattack. In order to avoid this situation, it is necessary to achieve a one-time accurate and rapid destruction of the enemy. Therefore, artillery must complete the precise strike of "multiple shells and a single target" in a short period of time, destroy the enemy at one time, and avoid our losses. Fire main battle artillery should have a modern fire control system, a fully automatic ammunition loading system, an automatic navigation system, etc., which greatly improves its rate of fire and hit probability.

[0004] When the artillery system is equipped with an automatic loader, rapid loading in a short period of time will make the artillery's attack and defense integrated, making it more powerful. Modern artillery with automatic loaders has the following advantages:

[0005] 1. Increase the firing rate of artillery: Traditional artillery ammunition loading requires the cooperation of multiple people, and sometimes mechanical tools are used to assist in loading. Manual loading is not only time-consuming, but also requires the cooperation of multiple people, and cannot achieve continuous operation tasks. However, the artillery system equipped with an automatic loader, under the control of the main control system, can start the preparation work for the next loading action after completing the loading of the previous shell. The actions of selecting and feeding the shells can be completed while the previous projectile is fired. The shells can be fed when the gun door is opened, and the automatic loader adopts mechatronic control, which is much faster than manual feeding.

[0006] 2. Improve reliability: Manual loading always has mistakes. The shells may slip out of sweaty hands. It is not uncommon to load the wrong shells or fail to push the shells into the chamber and close the gun port, especially in harsh environments. For example, in a self-propelled artillery on the move in the field, when the next shell is loaded into the barrel under unexpected circumstances such as bumps, pitching and deviation, this precise on-the-move shooting capability will be greatly reduced. The use of an automatic loader will not have such problems. It can provide continuous high-speed reloading in all-weather and harsh off-road conditions.

[0007] 3. Reduce the size of the artillery system: When the loader selects and loads ammunition in the fighting compartment, he basically works in a standing position, which takes up a large space and height. The use of automatic loaders eliminates the need for loaders, which can greatly save space in the fighting compartment.

[0008] 4. Improve the mobility of artillery: The use of automatic loaders can reduce the combat space and the armor that contains it. It reduces the weight of the artillery system and thus improves mobility.

[0009] The existing Chinese patent CN203758355U proposes "an automatic ammunition loading device for tanks". The invention proposes an automatic ammunition loading device for tanks, including a driving device, an information sending device and an automatic loader, and the automatic loader includes a magazine, an ammunition cartridge, a bullet pushing mechanism, a hoist and a bottom plate. However, the patent structure is relatively bulky, the control of the hoist is complex, and the energy consumption during the operation is large. Therefore, it is of low practicality and difficult to implement.

[0010] The existing Chinese patent CN206944814U proposes "an automatic belt-loading machine". The invention proposes an automatic belt-loading machine, including a workbench, a motor and a shuttle slot, a belt support frame, a cylinder and a push cam, etc. Its bullet pushing mechanism requires a high-pressure cylinder to discharge high-pressure gas through an air intake pipe to push the push cam forward to complete the assembly of bullets. Due to the large size of the shuttle slot, the heavy mass of the high-pressure cylinder, and the overall size of the loading mechanism, the possibility of assembling it on a weapon is relatively low.
