基于摩擦特性的轮式对虾背腹定向装置

摘要

In order to realize the automation of shrimp peeling ,a set of device was designed for decapitated shrimps ,which can make the shrimp’s back toward the desired direction .Based on the different friction properties of the shrimp's back and abdomen ,a set of device was de‐signed using three steering w heel to realize the decapitated shrimp's orientation ,and the exper‐iment was carried out using frozen shrimp of 11 .5-12 g .Both the theoretical analysis and ex‐periment results showed that this device could set the decapitated shrimps'backs toward the desired direction .When the diameter of the second driving wheel roller was60 mm and inner diameter was 43 mm ,the shrimp directional reliability was found stable .When roller speed was 69 r/min< R<145 r/min ,the device could guarantee the processing capacity not less than 100 kg/h .This experimental results may provide technology references for directional device design in shrimp automation processing .%为实现对虾剥壳自动化，设计了一种去头对虾背腹定向装置。以去头对虾为研究对象，根据对虾背腹摩擦特性，设计3个转向轮装置实现去头虾背腹定向，并采用质量为11．5～12 g的冷冻对虾进行了试验研究。理论分析和试验结果均表明，该定向装置可以实现对虾背腹定向；当第2主动轮辊子外径为60 mm ，内径为43 mm时，对虾定向稳定；第2主动轮转速要求69 r／min＜ R＜145 r／min ，可以保证加工能力不小于100 kg／h。研究结果可为对虾连续化加工中定向设备的产品开发提供技术依据。
