不对行棉秆拔取收获台设计与试验（Design and Experiment on Cotton Stalk Pulling Head with Regardless of Row）
拔棉秆机 不对行 拔取 设计
2010/12/29
针对棉花种植行距不统一，导致目前拔棉秆机适用范围小、效率低、功能单一等问题，设计了具有整理棉秆和分离泥土功能的不对行棉秆拔取收获台。简述了整机结构和工作原理，并对关键部件进行了理论分析、设计计算和选型，对样机的主要性能指标进行了田间测试。试验结果表明，拔茎辊转速502r/min、整机前进速度0.93m/s时，生产率为0.8hm2/h，拔净率为97.7%，各项指标达到了设计要求。
