摘　　要：针对大型青贮机宽幅割台配套短缺、现有割台幅宽小、收获效率低的问题,研发设计了工作幅宽为6.0m的折叠式青贮机立辊割台。利用Solid Works三维设计软件分别对切割喂入滚筒、分禾装置、割台变速器、液压折叠装置等进行了仿真设计。样机田间试验结果表明:青贮机收获效率高,作业切割输送顺畅,收获损失率为0.9%,割茬平均高度118mm,达到了设计要求,可为我国6.0m及以上的大型青贮机割台的研究提供参考。Aiming at the problems of less large harvester header,small amplitude,low harvesting efficiency of large silage machine,a folding vertical drum harvester header with working width of 6.0 m was developed and designed.The 3 D design software Solid Works was used to simulate the cutters,the feed drum,the branching device,the transmission and the hydraulic folding device.The field test results showed that the data met the design requirements.The silage harvester had high harvesting efficiency,smooth cutting and transportation,the harvest loss rate was 0.9%,the average height of stubble was 118 mm.It has important reference value for the domestic design of large harvester header above 6.0 m.
