玉米收获机摘穗装置主要结构和运动参数研究

Research on Main Configuration and Motion Parameters of Corn Combine’s Snaping Device

以4YW-2型玉米联合收获机为研究对象,利用试验台深入研究了摘辊间隙、螺旋筋升角、摘辊转速对收获过程中玉米茎秆沿摘辊轴向、周向运动速度的影响规律。结果表明:各因素与轴向运动速度呈线性关系,与周向运动呈非线性关系,摘辊间隙应该是设计中首要因素。

The process of picking is the main and vital work of corn combine,and the snaping device is the core part of corn combine.Through researching the laws of corn stalk’s motion in snaping device,the corn stalk’s motion law,and the main structure and motion parameters’influnce are available, which provides some design foundation for corn combine.
