设计简介
摘 要:马铃薯为地下产物,且是块茎繁殖,收获受季节和天气限制。由于马铃薯的收获费时费力、劳动强度大且季节性强,因此给农民造成极大的困难。为了解决上述问题,本文就国内外马铃薯收获机现状、马铃薯收获机的研究和应用进行介绍和分析,设计了组合分离式马铃薯收获机。对该机的主要参数进行了选择,对主要零部件的设计进行了理论计算。

Abstract: Potato is an underground plant. Its harvest is limited by the crown of the year and weather. Since the potato harvesting process has some difficult problems for farmers such as being strenuous and time consuming, great in labor intensity and urgent in seasonal demand. The paper analyses the present situation of potato harvest, and a combined separation potato digger has been developed through selection of principal parameters and theoretical calculation for the design of essential parts.
