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。

Abstract
China is a large agricultural country, the production of crops is large, so the processing of crops machines are increasingly in demand. In daily life, people's demand for food is also growing, among them peanuts, is a kind of crop that people like to eat. Peanuts can not only be directly consumed by people, but also can be processed into edible oil and a variety of nutrient-rich food, providing people with a wealth of protein. At present, China's production of peanuts not only solve the domestic population of peanut demand, and exports abroad. Therefore, the increase of peanut production is not only to solve the problem of population saturation, but also to provide a basis for the development of China's economic development. The development of agricultural machinery, that is, peanut processing automation machinery, is an urgent problem to be solved in China. The peanut shelling machine studied in this paper is the use of machines instead of manual labor, providing production efficiency and reducing processing costs.
The peanut shelling machine designed in this topic aims to replace manual labor with automated equipment, reduce people's labor workload and improve the production of peanuts. This paper mainly analyzes the structure of the existing domestic and foreign peanut shelling machine, the working principle, combined with the application of the actual peanut peeling machine, optimize the function of this automation equipment, design the transmission structure, through the calculation of the selection of transmission motor and other standard parts, and complete the design of the whole machine. Finally, by using 3D software, the design of peanut peeling machine to draw out, make it more intuitive, to ensure that the design is reasonable, with proper fit, compact and complete structure. In this paper, a well-functioning, stable equipment and high yield peanut peeling machine is designed to meet people's demand for peanuts.
