摘要

花生是传统的农作物，可以进行多种类深加工，现在花生产品和农业结构调整已经变成我国重点种植的农作物，其加工产品远销世界各地，在这种广阔的发展前景的推动下，花生生产势头猛涨，并有逐渐集中生产的趋势，一套成熟的产业链已经形成。然而中国花生生产机械化发展却严重阻碍了花生产业的发展，传统花生收获主要依靠人工完成，劳动强度大、作业成本高、效率低、损失大，这些问题已经严重制约着其产业的长足发展。本论文设计了振动筛式花生收获机的总体结构、工作原理、技术特点以及关键部件结构与工作参数设计等。该设备主要由挖掘铲、振动筛、行走轮、动力传动装置及机架等组成。此机械设备工作顺畅运行可靠，生产率：0.1～0.13hm2/h，荚果破碎率：1%，清土率高，损失率低,损失率：3%,，适用于个体较大规模的机械化生产，解放劳动力。
