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

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502 r/min、整机前进速度0.93 m/s时,生产率为0.8 hm2/h,拔净率为97.7%,各项指标达到了设计要求。

Because of variety of cotton row spacing,there were some problems on cotton stalk pulling machine such as smaller using scope,lower efficiency and function singleness etc.In order to solve the problems,a new cotton stalk pulling head with regardless of row which could rearrange cotton and separate soil was designed.The whole structure and operating principles of the pulling head were introduced,and the critical components were designed by theoretical analysis and calculations.The main performance indexes of a prototype were measured by field tests.The results indicated that production coefficient was 0.8hm2/h and pulling rate was 97.7%,when rotational speed of the pulling roller was 502r/min and advance speed was 0.93m/s,and all main parameter indexes reached their design requirements.
