摘　　要：茎秆切割是作物收获的关键环节,甘蔗、木薯等作物茎秆粗壮、质地硬,切割难度大,其切割装置的作业性能是影响收割机作业质量和效率的关键因素。为此,综述国内外硬质茎秆作物切割装置的研究进展,重点从硬质茎秆切割器的关键参数、切割阻力与功耗、割刀磨损等方面总结其存在的问题及研究现状,由此指出硬质茎秆切割装置研究存在茎秆建模过于简单、刀具材料研究不足、茎秆与刀具研究相分离、缺乏结构创新等问题。同时展望应加强基础研究、深入研究切割理论、开展仿生割刀研究、加强农机农艺相结合等相关发展趋势,以期为我国硬质茎秆作物收获机械化的研究提供参考。Stem cutting is a key link in crop harvesting.Sugarcane,cassava and other crops stem thick,hard texture,difficult to cut,cutting device performance is the key factor affecting the quality and efficiency of harvester operation.In this paper,the research status of hard stem crop cutting equipment at home and abroad was introduced.The existing problems and research status of hard stem cutter were summarized from key parameters,cutting resistance and power consumption,cutter wear and other aspects.It is pointed out that there are some problems in the research of hard stem cutting device,such as too simple modeling of stem,insufficient research on cutting tool materials,separation of stem and cutting tool,and lack of structural innovation.At the same time,it is expected to strengthen the basic research,in-depth research on cutting theory,carry out bionic cutter research,strengthen the combination of agricultural machinery and agronomy and other related development trends,in order to provide reference for the research of hard stem crop harvesting mechanization in China.
