摘　　要：针对柠条、沙棘、沙柳和紫穗槐等灌木植物机械化收获需求,研发设计了9L-200型灌木收获机。采用适合于沙地、沙坡、丘陵地和泥泞地的履带底盘,驱动采用定量液压泵+比例阀+变量行走马达;利用锯切原理,设计双圆锯盘向内旋转对灌木实施无支撑切割的切割拨送割台;开发组合式切碎滚筒装置;通过增减动刀和动刀刀架数量,实现切段长度的有级调整;设置了反转齿箱装置,达到快速排除堵塞的效果。经国家农机具质量检验检测中心现场检测及田间试验检测,该机生产率为0.40~0.67 hm2/h,物料切割长度20~40 mm可调,各项性能指标达到了设计要求,可满足大规模灌木平茬收获和工业化资源利用的市场需求。In view of demand of mechanized harvesting of shrub plants such as Caragana korshinskii,Hippophae rhamnoides L.,Salix cheilophila S.,and Amorpha fruticosa L.,the 9L-200 shrub harvester was developed and designed.Crawler chassis suitable for sandy land,sandy slope,hilly land and muddy land was adopted,and quantitative hydraulic pump+proportional valve+variable travel motor was used for driving.Based on sawing principle,a cutting and feeding header with double circular saw discs rotating inwards to cut shrubs without support was designed.Combined chopping drum device was developed.By increasing or decreasing number of moving knives and tool holders,stepwise adjustment technology of cutting length was realized.A reverse gear box device has been installed to achieve rapid removal of blockages.According to field inspection and field test of National Agricultural Machinery Quality Inspection and Testing Center,productivity of the machine was 0.40~0.67 hm2/h,material cutting length was 20~40 mm adjustable,and all performance indicators met design requirements,meeting market needs of large-scale shrub flat stubble harvesting and industrial resource utilization.
