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。

Abstract
With lifestyle changes, the simple packaging of peeled vegetables becomes many people's choice. At present, some of the lotus root productions are still using manual operation, which make low production and waste of labor.
Aiming at solving these problems, this paper designs a semi-automatic lotus root peeling machine, which carries out the research of key technology of machine： By analyzing the physical characteristics of lotus root, this paper determines the feeding mode of lotus root which has the radius of 10cm circular arc shape and the rotates root clamped by the double feed roll.
This paper determines the mechanism of the machine is friction-removing with the combination of dynamic and static brush wheels, and has 3 kinds of different peeling ways, which improves the fault-tolerant rate of the peeling; The paper determines many important parameters such as feed speed and brush wheel speed. At the same time, the transmission mode of the machine is determined, including bevel gear transmission and v-belt transmission and so on.
In this paper, the key components are analyzed by ANSYS, the results show that the strength and other indexes can meet the design requirements.
