Research and test of key components of the squirrel-cage bullet shell counter

Abstract In order to solve the problem of counting when the bullet shells is recovered, a kind of squirrel-cage bullet shells counters is designed. Through theoretical analysis and test, The angle of the bullet slot of the squirrel cage shell counter is 31.3 ° and the rotation speed of the cartridge mechanism is 10 R / min. The squirrel cage shell counter has the advantages of simple structure, few components, 3D printing technology, greatly reducing the weight and power consumption. The whole machine test results show that: The counting efficiency of the slot type bullet shell counter is 87.4 pieces / minute, and the counting accuracy is 99.8%. The counting efficiency and precision of the slot type bullet shell counter can meet the design requirements of the army. This research not only provides a practical shell counting tool for the military, but also provides a reference for the innovation, research and optimization design of other similar mechanical equipment.
