【摘要】 <正> 谷物康拜因上逐稭器的分离质量对脫出物的喂入量和湿度的变化至为敏感,喂入过多和湿度增大时分离就不淨。逐稭器由于其通过能力低,限制了机器生产能力的发揮,已成为康拜因上最薄弱的一环。目前在逐稭器的設計中用理論公式計算确定它的参数时,由于脫出物的运动复杂,性状多变,系数不易正确选定,其結果往往不可靠;因而設計者常常参考更多还原

【Abstract】 The length of straw shaker (L_T) is one of the most important parameters. The effect of separation by straw shaker is chiefly depended upon the thickness of straw layer, which is approximately determined by the degree of straw flow constriction (C_T: Ratio of machine working width to the straw shaker width).In this paper on the basis of statistical analysis of technical characteristics of 90 grain combine two empirical formulas indicating the relation between L_T and C_T for the straw walker and one-piece oscillating straw rack respectively are given. These empirical formulas are confirmed theoretically and by some borrowed experimental data to a certain extent.更多还原
