马铃薯收获机的设计
摘要: 马铃薯为地下产物,且是块茎繁殖, 其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。

The design of potato harvester
Abstract: Potato is an under ground 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 bined separation potato digger has been
developed through selection of principal parameters and theoretical calculation for the design of
essential parts.
