  畢業(yè)設(shè)計(jì)說明書（論文）中文摘要

本次課題為刀片式秸稈粉碎還田機(jī)設(shè)計(jì)。本次設(shè)計(jì)在市場(chǎng)上現(xiàn)有機(jī)械的基礎(chǔ)上對(duì)還田機(jī)進(jìn)行改進(jìn)，以滿足廣大農(nóng)民朋友的需要。
　　　本次設(shè)計(jì)包括刀軸的設(shè)計(jì)、變速箱的設(shè)計(jì)、傳動(dòng)裝置的設(shè)計(jì)、定刀的設(shè)計(jì)、刀軸焊接的設(shè)計(jì)。首先從成本考慮，在原有基礎(chǔ)上對(duì)機(jī)構(gòu)進(jìn)行簡(jiǎn)化，以降低成本。本次設(shè)計(jì)的還田機(jī)刀軸轉(zhuǎn)速很高，為了減震，對(duì)其刀片排列提出“均力免振假設(shè)”，建立數(shù)學(xué)模型，再利用計(jì)算機(jī)自動(dòng)計(jì)算軟件計(jì)算刀片的分布點(diǎn)。在刀具方面采用淬火回火處理，降低成本，本可以有效的提高刀具的使用壽命。

Title  the design of blade type machine made for crushing straw and returning them to the farmland
Abstract
This topic is the design of blade type machine made for crushing straw and returning them to the farmland .This design improve the machine according the existing machinery on the market to meet the need of farmer friends.
This design includes the design of tool axis,gear-box,transmission device ,fixed tool and jointing of the tool axis.Considering the cost first,we predigest the mechanism at the top of the original foundation to low the cost.in this design the revolving speed of machine blade shaft is very high. to reduce shake,"dynamic balancing principle"is lodged on arranging of the blades and the math model is created, making use of cumper automatism count software to calculate the distributing point of the blades.Adopt quench and temper on tool to low the cost, it can raise the service life of the tool.

Key words   razor blade type   dynamic balancing principle   quench and temper
