小型块茎类蔬菜（莲藕为例）去皮机设计DESIGN OF PEELING MACHINE FOR SMALL TUBER VEGETABLES (LOTUS ROOT) 摘要 随着生活方式的改变，简易包装的去皮蔬菜称为越来越多人的选择。目前部分莲藕的生产依然采用的是人工操作，具有生产效率低，浪费劳动力问题。旨在解决这些问题，本课题设计了一种莲藕半自动去皮机，本设计中关键技术的研究如下： 通过分析莲藕的物理特性，确定了双喂入辊旋转夹持的莲藕喂入方式；确定了本机器的去皮机理为动静刷轮结合的摩擦去皮，具有3种不同的去皮方式，并提高了去皮的效率；确定了喂入速度、刷轮转速等参数；同时确定了机器中的传动方式包括锥齿轮传动、V带传动等。最后，本文还对关键部件进行了ANSYS有限元分析，结果表明各项指标符合设计要求。 关键词莲藕去皮；动静刷轮；锥齿轮传动；ANSYS有限元分析 Abstract With lifestyle cha
