摘　　要：为了研制玉米秸秆皮穰叶分离设备,对剥穰机构进行了试验研究。利用试验台对其主要影响因素:剥穰刀与支持板间隙、剥穰刀数量、剥穰刀安装角和剥穰辊转速进行了试验,并以秸秆外皮完整率和含穰率作为评价指标。试验表明,当间隙2.0～3.0 mm、剥穰刀6把、剥穰刀安装角15°和剥穰辊转速1 000 r/min时,其外皮完整率达95%且含穰率低于2%。For studying the separation equipment for rind and pith of corn straw,the key mechanism for separation of rind and pith was experimented.In experiments,distance between pith-stripping blades and supporting blade,quantity and installation angle of pith-stripping blades,rotation speed of pith-stripping roll were chosen as experimental factors.Rind-intact percentage and pith-remain percentage were decided as evaluation indexes.The results showed that with distance of 2.0～3.0 mm,quantity of blades of 6 pieces,installation angle of blades of 15°and rotation speed of roll of 1 000 r/min,rind-intact percentage was over 95% and pith-remain percentage was below 2%.
