设计简介
摘要
目前，常见马铃薯去皮机多采用立式转筒型，立式结构多通过下端输入动力，上端悬置，这就使转筒存在运动不平稳的问题，同时，马铃薯主要依靠转筒底部的圆盘来达到去皮效果，而马铃薯依靠自身重力大多堆积在圆盘上，各马铃薯与圆盘接触的不均致使马铃薯去皮不均匀，去皮效果不佳。本文论述了解决以上两大问题的方法，即将转筒制成卧式，采用两端轴承固定的方法提高转筒运动平稳性，同时通过转筒筒壁上的凸起棱部分与马铃薯的摩擦来达到去皮效果，这使得马铃薯的去皮效果达到均匀且较佳。通过对两种去皮机各方面性能的综合对比，采用传统设计方法，获取整机各零件的参数，并且通过计算，论证了该设计方案的可行性，最终结论是卧式去皮机综合性能较立式去皮机更佳。

Abstract
At present, the common potato peeling machine adopts the vertical drum type, vertical structure in the lower end of the input power, the upper suspension, which makes the rotary movement exists unstable problem, at the same time, potato mainly rely on the drum at the bottom of the disk to achieve the peeling effect, and potato on its own gravity mostly accumulates on the disc, the potato contact with the disk does not have led to peel the potatoes peeled uneven, poor effect. This paper discusses the method ,to solve two problems the drum made of horizontal, with both ends of bearing fixing method for improving the rotary motion stability, at the same time through the rotating barrel wall convex edge part and potato friction to achieve the peeling effect, which makes the potato peeling effect to achieve uniform and better. Through to two kind of peeling machine all aspects of the comprehensive comparison, using the traditional design method, acquiring the various parameters of parts, and through calculation, it proves the feasibility of the design, the final conclusion is that the horizontal peeling machine comprehensive performance than vertical peeling machine.
