摘　　要：本文设计了一种自走式密植棉秆整株收获机,可实现对棉秆田间根侧切土减阻、铲拔、捡拾输送及收集作业。利用Solidworks软件对自走式密植棉秆整株收获机进行三维建模,并对关键作业部件进行静力学仿真分析。静力学分析结果表明,铲拔刀的最大等效应力为158.94MPa,最大总变形为0.093mm,受力后的等效应力与总变形均低于所选材料的承受极限,材料选用安全可靠,符合设计要求。分析结果为该机进一步优化设计提供理论参考,同时可为大田作物秸秆收获机械研究和发展提供新思路。In this paper,the design of a self-propelled close planting cotton stalk harvester was expounded.Through the application of this machine,the soil cut on the side of root for reducing the resistance,shoveling,pick up,transport and cotton stalk collecting can be realized.The 3 D model of self-propelled close planting cotton stalk harvester was established by SolidWorks software,and the static simulation analysis of key operation components was carried out.The results of static analysis indicated that,the maximum equivalent stress of the shovel cutter was 158.94 Mpa,and the maximum total deformation was 0.093 mm.The equivalent stress and total deformation after loading were lower than the bearing limit of the selected material.The material selection was safe and reliable and met the design requirements.The analysis results provided a theoretical reference for the further optimization design of the machine,and provided a new idea for the research and development of field crop straw harvester.
