Experimental Study on Soybean Cleaning Using Reciprocating Vibration Screen

摘要: 为综合研究筛子工作参数对筛上谷物运动和筛下物获选率的影响，对筛面倾角、曲柄半径、曲柄转速和振动方向角进行了正交旋转设计。用 ^６０Ｃｏγ示踪技术测试了筛上谷物运动，分别建立了谷物运动速度、筛下物获选率与筛子工作参数之间的回归方程，分析了谷物运动速度对筛下物获选率的影响，提出了两组筛子最佳工作参数。

Abstract: To study the effect of screen working parameters on the motion of the oversize and on thesifting percentage of the siftage,the orthogonal design was made in terms of sifter angle, crank radius, crank speed and vibrating angle. The motion of the oversize was tested by means of ^６０Coγ tracertechniqueand the regression equation was made about the screen working parameters. The effect of the grain motion on the sifting percentage of the siftage was analysed and two sets of optimum screen working parameters were obtained.
