超精型花生联合收获机的总体设计 摘要 超精型花生联合收获机双行作业，将花生的藤、果和土一同起耕。三者一次性分离，一次完成花生的联合收获作业。具体的工作过程包括：分扶藤苗，起耕，梳果，碎土，输藤，清送，输果。 超精型花生联合收割机根据花生的生长特点以及收获的工艺要求，合理地设计出关键工作部分，使得机构具有结构紧凑、重量轻、分离彻底的特点。采用多面型粉碎齿，第一道粉碎就可以使土块的破碎率达到70%以上；摘果刀片用于藤果分离；由输送轮将藤苗输向后面并抛出；分土后的花生进一步清选后落入果箱。收获后的果子可以直接上常 该机器的成本低，适合小批的花生种植收获。其工作效率相对于手工作业有了跨越性的提高。 关键词：超精型；高效；分离彻底；低成本 ABSTRACT Two-li
