1、振动筛式花生收获机的设计摘要：花生是重要的油料作物，花生含油量高于油菜和大豆，我国花生产量占油料总产40%左右。花生不仅是优质油料作物，而且是主要的蛋白资源，加工品类多，产业链条长，现已成为我国重要的出口创汇产品和农业结构调整重点发展和扶持的种植品种。我国不仅是世界花生的生产大国和消费大国，也是贸易大国。花生种植，在世界范围均属劳动密集型产业。中国劳动力丰富，花生种植和出口具有明显优势。期以来，由于花生种植、收获和加工大都靠人工完成，但劳动强度大、效率低。而在整个花生生产过程中，收获环节用工占全过程的1
2、/3以上，占整个花生生产成本的50%以上。推动中国花生生产机械化发展，对降低作业成本，提高作业效率、促进农民增收，具有现实意义。本设计的振动筛花生收获机主要由挖掘铲、振动筛、行走轮、动力传动装置及机架等组成，并与功率为12kw左右的拖拉机配套使用，可以同时实现一次完成多行花生收获。收获过程中，挖出来的花生秧被传送到振动筛上，振动筛的振动可实现去除挖掘出的花生所带有的泥土，最后通过输送板实现花生秧一侧倒伏的工作原理。能大力提高花生收获的工作效率，降低收获成本，并实现机械化的生产。关键词：花生;振动筛;收获
