拨禾指式玉米摘穗机构拨禾区段功能分析

Analysis of Feed-in Section in Corn Snapping Device with Finger Wheel

针对拨禾指玉米摘穗机构拨禾指曲线形状对拨禾输送性能的影响,分析了拨禾曲线工作过程在各工作区的功能,提出了横向拨禾α1区、螺旋喂入α2区、摘穗分禾α3区、拨穗α4区4个区域功能区段的作用与要求,初步建立了适合各功能区段要求的拨禾指曲线模型,并对模型进行了试验验证。

Focus on the impact of the shape of finger wheel in corn snapping device with finger wheel on delivery per -formance , proposed functions and requirements in lateral transport area α1 , spiral feeding areaα2 , harvesting areaα3 and ear-rotor areaα4 , initially established the shape model of finger wheel for each function zone requirements , and the mod-el is verified by test .
