联合收割机的生产率是以滚筒的额定喂入量(公斤/秒)为标志的。它的设计依据是分离机构的分离能力,即裹粮损失不超过0.5%时的最大喂入量。故此,农机工作人员也常把联合收割机的脱粒与分离机构的关系比做人的嘴(吃)与胃(消化)的关系。联合收割机的分离装置——逐稿器,大致有三种类型,即回转式、平台式和键式逐稿器。科学理论和生产实践都已证明,键式逐稿器(以下简称键簧)的分离性能优于回转 Combine harvester productivity is based on the rated feed roller (kg / sec) for the mark. Its design is based on the separation capability of the separation mechanism, ie the maximum feed when the loss of the coated grain is no more than 0.5%. Therefore, the agricultural machinery workers often combine harvester threshing and separation mechanism than the relationship between human mouth (eat) and the stomach (digestion). Combine harvester separation device - by - draft, there are roughly three types, namely, rotary, platform and key by the draft. Both scientific theory and production practice have proved that the separation performance of the key-press (hereinafter referred to as the key spring) is superior to the revolution
