对虾剥壳设备的自动定向与分级控制

目的:实现对虾深加工的全自动化。方法:在分析南美白对虾形体特征的基础上,根据对虾重心位于虾体最厚处与虾尾之间的特点,设计一种对虾头尾自动定向与分级控制装置。以定向辊轴线与水平线的夹角、定向辊转速为试验因素,对定向部件进行试验。结果:当定向辊转速为60 r/min,轴线与水平线夹角为15°时,对虾下落速度均匀平稳,头尾定位成功率高,有利于对虾后续的分级输送。结论:该装置实现了对虾头尾定位及分类,有利于对虾加工的全自动化。

Research on automatic orientation and grading of shrimp shelling device

Objective: To realize the full automation of shrimp deep processing. Methods: Based on analysis of physical characteristics of northern and southern American shrimps, according to the feature of the center of gravity located between the thickest part of the shrimp body and the tail of the shrimp, an automatic orientation and grading device of shrimp head and tail was designed. Taking the clip angle between directional roller shaft line and horizontal line and the speed of directional roller as testing factors, the directional components were tested. Results: When the directional roller speed was 60 r/min, and the angle between axis line and horizontal line was 15°, the falling speed of shrimp was even and stable with high directional rate, which was benefit for subsequent grading transportation. Conclusion: The device realizes the shrimp head and tail positioning and classification, which is conducive to the full automation of shrimp processing.
