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,收获受季节和天气限制。据我的了解,马铃薯这种农作物的收获难度系数很大,而且从季节的角度看它的季节性很强而且,由于长年都没游戏的关于这方面的机械研究产品,所以给农民带来了很大的困扰,本课题就是以为了解决上述问题为研究目的来对马铃薯收获机进行研究,对这个机械产品进行应用上的分析。同时我设计的这是组合分离式马铃薯收获机。主要就是对此机械产品的主要参数进行了准确的选择选择,对主要零部件的设计进行了精准的理论计算。同时做出相应的CAD图纸用来一目了然的了解到我的设计。最重要的是要从实际情况中来确定研究思路,所以我就深入到种植场地上认真观察实际情况,这一举措对我的设计确实帮助不少。而且从往年国内外的期刊杂志上了解了很多情况,让我对此设计又增加了不少信心,思路更加清晰,做出的设计必须要满足实际要求。?

Design of potato harvester
Abstract: the potato is a product of the underground, and it is the tuber propagation. The harvest is restricted by seasons and weather. According to my understanding, the potato crop harvest difficult coefficient and from the point of view of the season see its seasonal very strong and, due to the long-term game of on the study of mechanical products, so to farmers brought great distress, the subject is in order to research purpose to study of potato harvester, the mechanical products for application on the analysis of the problem to solve. At the same time I designed this is a combination of separate type of potato harvester. Mainly is the main parameters of this mechanical products to choose the correct choice, the design of the main parts of the precise theoretical calculation. At the same time make the corresponding CAD drawings for a clear understanding of my design. The most important is to determine the research ideas from the actual situation, so I went deep into the planting site carefully observe the actual situation, this initiative to my design really help a lot. And from the domestic and foreign periodicals in previous years to understand a lot of things, so I designed to add a lot of confidence, ideas more clearly, to make the design must meet the actual requirements.
