割前脱粒联合收割机摘脱割台流场分布实验研究

Experiment Research of Air Flowing Speed Distribution on Header for Stripper Combine

应用激光多普勒测速装置对割前脱粒联合收割机摘脱滚筒周围气流速度大小进行了测试 ,利用所测的结果建立了气流分布的回归方程 ,为精确地描述摘脱割台脱出物的运动轨迹 ,找出其分布规律 。

The flowing speed distribution between stripper rotor and hood was qualitatively analyzed for stripper combine. With the Laser Dopper Velocimeter device, the velocity of air current around the stripper rotor was measured. By using the results the mathematical model of the air flowing velocity was constructed with regression method. It constructs the basis for accurately describing the threshed grain trace and falling place law.
