摘要:

研究了清田整地聯(lián)合作業(yè)機(jī)齒形刮板式殘膜、殘茬及土壤輸送裝置的結(jié)構(gòu)原理,，分析計(jì)算刮板組工作行程的阻力,、功耗和動(dòng)能,。以刮板組工作行程的功耗,、動(dòng)能消耗最小為目標(biāo)函數(shù),，建立優(yōu)化設(shè)計(jì)的數(shù)學(xué)模型,，優(yōu)化計(jì)算結(jié)果為刮板寬度890mm,，高度260mm,，間距500mm,，工作速度2.5m/s，工作角度33°。通過試驗(yàn)表明優(yōu)化設(shè)計(jì)結(jié)果合理,，并確定了第1排刮板齒尖與起膜鏟刃口的最佳距離為

Abstract:

300mm,。The structural principle of zigzag scraper transportation device in combine machinery for field cleaning and land preparation operations, which is used for remnant plastic film, stubble and soil, was studied. Meanwhile, the resistance, the energy consumption and power were analyzed. An optimization mathematical model was established for the pursuit of minimal energy consumption. The optimization results including the length of scraper 890mm, the width 260mm, the distance 500mm, the working speed 2.5m/s and the working obliquity 33°were obtained by calculation. Finally, the results were validated by experiment. The optimal distance between the first scrapers and loosening shovels was 300mm.  
