【摘要】 本文测定了重力式种子精选机台面上物料的粒重分布,记录了台面上表层及底层物料的流动方向。通过实验,搞清了振动及气流对于物料垂向偏析运动的作用效果。分析了结构参数及运动参数对表、底层物料纵向交错运动的关系,讨论了若干因素对物料沿台面合成运动的影响。更多还原

【Abstract】 In this paper, we measured the distribution of the weight of seeds on the platform, made a record of flow direction of surface layer and bottom layer materials on the platform.By means of tests, the relationship between vibration and air flow to the process of deviation of material in vertical direction is cleared. Influence of structure parameters and motion parameters on longitudinal staggered motion between surface layer and bottom layer materials are analyzed. Influence of several factors on composition moving direction of materials on platform is also discussed.更多还原
