| 摘 要： | 分析了三层滚筒式银杏分级机的结构特点及工作过程，并对分级机的分级性能及筛孔大小进行了试验研究。试验结果表明：滚简体转速是影响分级机分级性能的主要因素，而倾斜角对分级机分级性能的影响不显著；分级机各层滚筒筛应采用扩孔筛，且扩孔系数应从内层滚筒至外层滚逐渐增大。

| 关 键 词： | 银杏 分级机 三层滚筒筛 分级性能 扩孔系数 |

| Abstract: | This paper analyzed the structure and the working process of three-layer-cylindrical grader and the grading performance and screen mesh-size are experimentally studied.The results indicated that the rotating speed has obvious effects on grading performance,but the inclination has not such effects.The enlarged oblonghole screen can be used in three-layer-cylindrical grader,and the coefficient of enlarged oblonghole should be increased linearly from inlayer-cylinder to outlayer-cylinder. |

| Keywords: | gingko nut grader three-layer-cylindrical screen grading performance coefficient of enlarged oblonghole |
