中文摘要：

在采茶人工成本不断增加、采工紧缺以及无法实现智能采摘的压力下,机械化将代替人工采摘茶树鲜叶。机械化采摘鲜叶存在等级混乱、芽叶破碎等问题。通过风选机、色选机和筛选机等分选设备对鲜叶进行分选研究现状进行分析比较,提出鲜叶智能分选机的设计思路,将实现对鲜叶进行高准确、高效率地分选。

英文摘要：

Under pressure of increasing picking labor cost,fewer picking tea workers and impossible intelligent picking,mechanized picking will be applied to picking fresh tea leaves instead of artificial picking.Mechanized picking still exist some problems on fresh leaves＇grade confusion and broken bud leaves.On this paper,we analysis and compares current situation of fresh leaves sorting by winnowing sorter,color sorter,and screening machine,putting forward the design idea of intelligent sorting machine to achieve high accuracy and efficiency for fresh leaves sorting.
