摘　　要：打结器是方草捆机的核心部件,目前国内外主流型式是D型打结器。受生产质量、工作环境、使用保养等因素影响,国内实际打捆作业过程中D型打结器往往过早失效,制约了牧草、秸秆的及时收获,增加了作业维护成本。因此,明确D型打结器失效形式,分析D型打结器损伤机理,归纳总结打结器改进措施,有利于改善打结器工作效果,为打结器设计制造国产化提供技术支持。Knotter is the core component of square straw bundling machine,and the main type of it is D type both at home and abroad.Practically,D type knotter usually becomes premature invalid during the bundling process,because of production quality,working environment,maintenance,and other factors,which restricts the timely harvest of grass and straw,and also increases the cost for maintenance.Hence,clearing the failure mode,analyzing the damage mechanism and summarizing the improvement measures of D type knotter have great advantages for improving its working effect.The conclusions can provide technical support for the localization of knotter design and manufacture.
