摘　　要：为解决菲律宾蛤仔分级称量准确率不高,工序协作度不足等问题。实验以菲律宾蛤仔为研究对象,研制滚筒筛分级匹配自动称量的菲律宾蛤仔分级称量集成装备。基于离散元仿真对菲律宾蛤仔分级称量过程进行模拟分析,采用Design-Expert软件进行响应曲面分析,探究滚筒筛转速、滚筒筛倾角及喂料量对分级准确率和称量准确率的影响,优化整机作业参数,并进行整机作业验证。结果显示,各因素对菲律宾蛤仔分级准确率和称量准确率影响的主次顺序为滚筒筛倾角>滚筒筛转速>喂料量,在滚筒筛转速为17 r/min、滚筒筛倾角为3°、喂料量为200 kg/h的作业条件下,装置分级准确率为96.09%,称量准确率为98.79%。完成样机制造及分级称量作业验证,分级准确率为96.56%,称量准确率为98.16%。研究表明,在菲律宾蛤仔分级称量过程中,合理设置滚筒筛的倾角、转速、喂料量等工作参数,可以实现较高的分级准确率和称量准确率。本研究可为贝类捕后分级称量装置设计提供参考。This study utilized Ruditapes philippinarum as the research subject to develop integrated grading and weighing equipment featuring drum screen grading coupled with automatic weighing to address the issues of low accuracy in grading and weighing R.philippinarum,as well as insufficient procedural coordination.Utilizing discrete element simulation,the grading and weighing processes of R.philippinarum were simulated and analyzed.The impact of roller screen rotational speed,roller screen tilt angle,and feed capacity on grading and weighing accuracies was investigated using response surface analysis in Design-Expert software.This study aimed to optimize the operational parameters of the complete equipment and validate its performance.The findings indicated that the primary factors affecting the accuracy of grading and weighing R.philippinarum,in descending order of influence,were the roller screen tilt angle,roller screen rotational speed,and the feed capacity.The device achieved a grading accuracy of 96.09%and a weighing accuracy of 98.79%under operational conditions of a roller screen rotational speed of 17 r/min,a roller screen tilt angle of 3°,and a feed capacity of 200 kg/h,.After completing the prototype manufacturing and operational validation,the grading accuracy was recorded at 96.56%,and the weighing accuracy at 98.16%.The results demonstrated that setting appropriate parameters for the roller screen tilt angle,roller screen rotational speed,and feed capacity could significantly enhance grading and weighing accuracies in the process of handling R.philippinarum.This research provides valuable insights for the design of post-harvest grading and weighing devices for shellfish.
