摘　　要：研究了清田整地联合作业机齿形刮板式残膜、残茬及土壤输送装置的结构原理,分析计算刮板组工作行程的阻力、功耗和动能。以刮板组工作行程的功耗、动能消耗最小为目标函数,建立优化设计的数学模型,优化计算结果为刮板宽度890 mm,高度260 mm,间距500 mm,工作速度2.5 m/s,工作角度33°。通过试验表明优化设计结果合理,并确定了第1排刮板齿尖与起膜铲刃口的最佳距离为300 mm。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 890 mm, the width 260 mm, the distance 500 mm, the working speed 2.5 m/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 300 mm.
