摘　　要：设计了一种棉秆对行起拔及残膜回收一体机,可完成边膜铲切和棉秆对行分禾、导秆、拔秆、输送、侧边铺放及表层残膜全量回收作业。利用SolidWorks软件对机具进行了三维几何建模,并对主要工作部件进行了设计计算,对棉秆起拔机构的机架进行了ANSYS静力学分析、疲劳寿命分析,结果表明:机架在正常工作下的最大位移为0.51605 mm,最大应力为78.75 MPa;循环10万次无疲劳失效,最大等效交变应力为80.39MPa,远低于机架材料的最大屈服强度。研究结果将为该机后续的改进设计提供理论参考。In this paper,an integrated machine of cotton stalk row pulling and residual film recovery was designed,which can complete the operations of edge film cutting,row dividing,guiding,pulling,conveying,side laying and surface residual film recovery.In order to ensure the rationality and applicability of the machine,three-dimensional geometric modeling of the machine is carried out by using SolidWorks software,and the main working parts were designed and analyzed.The frame of cotton stalk pulling mechanism was analyzed by ANSYS static analysis and fatigue life analysis.The results of static analysis showed that the maximum displacement of frame under normal working condition was 0.51605 mm,the maximum stress was 78.75mpa.The fatigue life analysis showed that there was no fatigue failure after 100000 cycles,he maximum equivalent alternating stress was 80.39 mpa,which was far lower than the maximum yield strength of frame material.The research results will provide a theoretical reference for the subsequent improvement design of the machine.
