马铃薯去皮机结构设计 摘要 马铃薯去皮是马铃薯进行深加工的主要工序之一。目前，马铃薯去皮虽然已经开始依靠机械进行生产，但劳动的强度也比较大、生产效率低下。结合当前对马铃薯去皮技术的调研和分析,在目前技术和消费条件允许的情况下研究和设计改造一款操作更加简单安全,使用寿命更长的马铃薯去皮机，使之生产效率更高,以便于节省人力资源。本文设计了一种基于摩擦原理的小型机械式马铃薯去皮结构设备。该设备主要由电动部分、传动部分和存储部分组成，该系统通过电动机连接一级减速器带动滚刷和传动结构摩擦旋转，由进料口把物料放入滚筒进行工作，通过卸料口卸出物料，从而达到对马铃薯去皮的目的，该设计通过对现有设备的数据进行分析、方案的研究和数据的计算,完成了该马铃薯去皮机构的总体设计，通过马铃薯去皮机的设计主要工作系统,这样马铃薯去皮机可以更安全,稳定和正常运行,提高马铃薯去皮过程的机械化程度。 关键词：马铃薯去皮机；摩擦；传动；去皮 ABSTRACT The potato ski
