一般情況下，他還勉強能找到不少活，如幫人接羊羔，犁犁田之類的事，以此來維持春閑和初夏時的生機。Based on the analysis of the real work state of the tractor in the field, take the typical plough implement unit as an example ; a further study was made in this paper, including the theory of the automatic transmission and the quality of gearshift
本文以典型的犁耕機組為例，在分析拖拉機田間作業工況的基礎上，深入研究了拖拉機自動變速系統理論及換檔品質的問題，改進了換檔執行機構，用模糊控制方法對換檔品質進行了優化。Based on wide - ranging knowing the mechanical technology of overturning crops stalk into soil inland and overseas, combined with the present condition and the requirement of the mechanical technique developing, aimed at the tendency of the remained stalks heightened of food crops in south china, the thesis brings up an mechanizing technical project and mating device, which contain the function of plowing soil and overturning crops stalk on the base of plough. it is tightly packed, reliable and can be used conveniently
本文是在對國內外秸稈還田機械技術廣泛了解的基礎上，結合我國秸稈還田的現狀及其對機械技術發展的需求，針對我國南方主要糧食作物收獲后滯留在田間的秸稈日益增高的態勢，提出了一種基於犁耕基礎上的集土壤翻耕與高稈翻埋功能於一體，結構緊湊、使用方便、性能可靠的機械化技術方案及配套裝置。The thesis had done the theories analysis in detail and built the relevant mathematics models aiming at the mechanics characteristic about the lodging of stalk, the elastic and plastic deform of stalk under the action of the transverse loads, the mechanics condition which causes stalk pushed, the relation between the speed of unit and the surface radius of ski, the relevant location between the thickness of the compressed stalk and action location of load, the relevant location between the mating device and plough, the coefficient of overturning soil under the thickness of the compressed stalk and so on. in addition, the computer aided analysis and simulating experiments in field were acted by choice
本文對秸稈自倒伏力學特性；橫向載荷作用下的莖稈彈塑性變形與秸稈被推倒的力學條件；機組作業速度與滑撬曲面半徑的關系；秸稈壓實厚度與加載作用點的相對位置；配套裝置與犁體相對位置；秸稈壓實厚度下的翻垡系數等，進行了較詳細的理論分析並建立了相關數學模型。在此基礎上，本項研究還選擇性地進行了計算機輔助分析和田間模擬試驗。Suddenly ploughed tracts and irrigation channels appeared, and the glisten of flooded rice - fields ; and cranes preceded the suburbs of mari
