摘要 我国是一个农业大国，对农作物的生产量大，因此加工农作物的机器也日益需求量大。而在日常生活之中，人们对食物的需求量也越来越大，其中花生，是人们喜欢食用的一种农作物。花生不仅可以直接被人食用，而且还可以加工成食用油及各种营养丰富的食品，提供人们着丰富的蛋白物质。目前，我国生产的花生不仅解决了国内人口对花生的需求，并对国外出口。因此，花生产量的提升，不仅仅是解决人口温饱的问题，还为我国的经济发展提供了发展基础。而发展农业机械，即花生加工自动化机械，是我国急需解决的问题。本文研究的花生摘果机，是利用机器代替人工劳作，提供了生产效率，降低了加工成本。 本课题设计的花生摘果机以自动化设备代替人工劳作为目的，降低人们的劳动工作量，提高花生生产产量。本文主要通过分析现有国内外花生摘果机的结构，工作原理，结合实际上花生摘果机的应用，优化改善此自动化设备的功能，设计传动结构，通过计算选择传动电机等标准件，并完成整套机器的设计。最后通过使用三维软件将设计的花生摘果机绘制出来，使其更加直观，保证设计合理，配合得当，结构紧凑完整。本文设计了一种功能完善，设备稳定，产量高的花生摘果机，以满足人们对花生的需求。 关键词:花生；花生摘果机；传动结构；设计；三维建模 Abstract Chi
