设计简介
摘要
随着农业发展，旋耕机的研究与生产也越来越广泛。各种用途的旋耕机都相继面世。旋耕机的用途的不同自然是有他们的主要工作部位决定的，因此旋耕机刀片的研究就尤为重要重要，各种各样的道具有外型不一也有同一系列不同材料的刀具。对于一台旋耕机而言或者说对于生产而言选取一款最适合的刀具是重中之重。所以相应的对比刀具的性能才是选择的关键。通过我对市场的有关方面的调查和了解发现，先进社会并没有相关的对比刀具性能的机器，这对于需要选用刀具的单位或者个人而言，没有明确的信息供他们合理的选着。针对现状我设计了一台旋耕机刀片专用磨损试验机供对比刀具性能实用。
我所设计的旋耕机刀片专用磨损试验机的工作原理是利用电动机提供动力带动链接转轴的带轮传动，使轴高速转动，从而使得轴上的刀具与磨料高速摩擦，通过对比一段时间的后刀具的磨损情况来对比刀具的耐磨性。
本设计的主要特点在于所设计的机构非常简单，实用性较强，生产此磨损试验机难度很小。而且此机械工作原理以及操作简单，其所用的材料普通，所以本机的制造成本不仅很低而且适用性很强，并且对于使用者基本上没有技术要求。本设计利用Auto CAD软件绘制相关的图纸，并用Pro/ Engineer软件进行实体建模。

Abstract
Agricultural development, the the rotavator the research and production is also more extensive. The various uses of rotary tiller have been published. The rotavator the use of different natural is their main work site decision, rotary tiller blade is particularly important to a wide variety of Tao has a shape different tool of the same series of different materials. For a rotavator or select a most suitable tool is the most important in terms of production. So the key to the performance of the comparison tool is selected. By the market parties to investigate and understand advanced social comparison tool performance machine for the unit or individual of the need to use the tool, there is no clear message for their election. For the status quo, I designed a rotary tiller blades wear testing machine for comparison tool performance and practical.
I designed the rotary tiller blade for wear testing machine works by the use of electric motor drive link shaft pulley transmission, axis high-speed rotation, so that the axis of the tool and the abrasive high-speed friction, by comparing the period of time the wear of the tool to compare the wear resistance of the tool.
The main features of this design is that the institutional design is very simple, practical strong, difficult to produce this wear test machine is very small. And mechanical work as well as simple operation, and its use of ordinary materials, the manufacturing cost of the machine is not only low but also the applicability of a strong and virtually no technical requirements for the utility. The design using Auto CAD software to draw the relevant drawings and Solid Modeling with Pro / Engineer software.
