Quick loading and unloading device for artillery

Abstract

The invention discloses a quick cannonball loading / unloading device for an artillery. The quick cannonball loading / unloading device comprises a machine body, wherein a power driving system, a cannonball pushing arm assembly, a cannonball toggling mechanism and a cannonball supplying mechanism are arranged on the machine body; the power driving system comprises a motor and an eccentric wheel; the cannonball pushing arm assembly comprises a guide bush; the cannonball toggling mechanism comprises a chain toggling driving shaft, a cannonball toggling lever and a cannonball toggling arm; the cannonball supply mechanism is arranged above the driving shaft and comprises a cannonball feeding box, a cannonball feeding valve, a cannonball feeding shifting fork and a driving ratchet. By adopting the scheme provided by the invention, the quick cannonball loading / unloading device has the advantages of high pressing speed of a 25mm artillery cannonball, high efficiency, convenience for carrying, capability of being quickly combined and detached, fewer needed persons, low work intensity and the like.

Description

technical field [0001] The invention belongs to the field of weapons and equipment, in particular to a rapid loading and unloading device for artillery. Background technique [0002] The 25mm automatic gun is the main battle weapon of our army's light armored equipment. Its ammunition supply method adopts a belt-type ammunition supply. Before shooting, it is necessary to use a bomb press to press the shells on the chain, and then load the shells on the automatic gun for shooting. . And there are three problems in the loading and unloading machine equipped by the army at present: 1, the bullet pressing speed is slow, takes a long time, and the work efficiency is low. On average, only 20-22 rounds of shells can be press-loaded per minute, while the ammunition base for a 25mm automatic gun is 400 rounds, and it takes nearly 20 minutes to press-load (without failure), and a company of 10 vehicles has 4,000 rounds of shells. It takes nearly 4 hours to complete the bomb pressin...

AI Technical Summary

Problems solved by technology

And there are three problems in the loading and unloading machine equipped by the army at present: 1, the speed of pressing the bomb is slow, it takes a long time, and the work efficiency is low

On average, only 20-22 rounds of shells can be press-loaded per minute, while the ammunition base for a 25mm automatic gun is 400 rounds, and it takes nearly 20 minutes to press-load (without failure), and a company of 10 vehicles has 4,000 shells. It takes nearly 4 hours to complete the bomb pressing, which greatly delays the preparation time

2. The labor intensity of the crew is high, and the operation continuity is poor

When preparing for combat, the crew needs to work manually for 4 hours in a row to complete the pressing work, and then reload the automatic gun. The working time is long and the labor intensity is high, which seriously affects the efficiency of combat preparation.

3. The operating procedures are cumbersome and the failure rate is high

The loading and unloading machine requires the cooperation of many people in the operation process to complete the loading and unloading action, and the operation is relatively cumbersome; and due to design defects, the loading and unloading action is relatively rough, and the linkage mechanism is unreliable, which often leads to the shell being out of order. If the alignment is not in place, it is prone to situations such as improper pulling of the bullet, jamming, poor combination of the shell and the chain, and even serious safety hazards.
