摘    要
本文對(duì)旱地立式驅(qū)動(dòng)耙的整體結(jié)構(gòu)和工作原理及旋刀運(yùn)動(dòng)軌跡進(jìn)行分析，并對(duì)主要的結(jié)構(gòu)參數(shù)和工作參數(shù)與旋刀平均工作阻力及每個(gè)刀盤功耗之間的關(guān)系進(jìn)行了分析。
在滿足農(nóng)業(yè)機(jī)械設(shè)計(jì)要求和機(jī)組配套掛接的要求下，給出了三套結(jié)構(gòu)設(shè)計(jì)方案，結(jié)合結(jié)果分析，擬確定了一套具有較強(qiáng)實(shí)用性和經(jīng)濟(jì)性的結(jié)構(gòu)設(shè)計(jì)方案。

Abstract

In this thesis, dryland vertical rake drive the overall structure and working principle of rotary cutter trajectory analysis, the establishment of a mathematical model of the major structural parameters and operating parameters of rotating knives and an average of resistance and power consumption between each cutter Analysis of the relationship
Agricultural machinery to meet the design requirements and unit articulated supporting the request, given the structural design of three sets of programs, combined with the results of analysis, to determine the practicality of a strong structure and economic design.
Key words  Vertical drive rake  Rotary knife   Parametric Analysis   Structural Design
