摘要
目前国内扇贝剥壳取肉仍以手工为主,加工环境恶劣、生产效率低。为改善这一现状,本文设计了一种针对海湾扇贝的仿人工剥壳机。仿照手工刀具剥离贝柱原理,采用弹性刀片,由气缸推动刀片贴合扇贝曲面对闭壳肌进行剥离。采用轮盘式布局,主要由贝壳切割组件、闭壳肌剥离组件等组成。利用MATLAB对测量数据进行分析,确定了闭壳肌的位置以及贝壳切割装置的切割位置距离贝壳边缘8 mm。通过Origin对扇贝壳体进行曲线拟合,建立扇贝内壳的几何模型,确定闭壳肌剥离刀片的尺寸宽b=20 mm、长l=14 mm,扇贝平均开口角度β=27°,弯曲角度范围α=2°~5°,并利用Adams进行仿真分析。试验结果表明,海湾扇贝剥壳机的剥壳成功率在85%以上,剥壳效率为20个/min,剥壳机满足扇贝加工品质及生产效率的要求。
At present,the domestic scallop shelling and meat extraction are still mainly done by hand,and the processing environment is harsh and the production efficiency is low.In order to improve this situation,an artificial peeling machine for bay scallops is designed.It is based on the principle of manual cutter peeling off the shells,using elastic blades,and the blades to fit the scallop curved surface to peel off the adductor muscle is pushed by the cylinder.The roulette layout is adopted,it is mainly composed of shell cutting components and adductor muscle components.The measurement data was analyzed by MATLAB,the position of the adductor muscle and the cutting position of the shell cutting device are 8 mm away from the edge of the shell.The scallop shell body was curve-fitted by Origin to establish a geometric model of the scallop inner shell.The size of the scallop muscle peeling blade b=20 mm wide l=114 mm long,the average opening angle of the scallopβ=27°,and the bending angle rangeα=2°~5°.Simulation analysis with Adams.The test results show that the success rate of the bay scallop shelling machine is over 85%,and the shelling efficiency is 20 pieces/min.The shelling machine meets the requirements of scallop processing quality and production efficiency.
