摘要花生中富含脂肪和蛋白质，既是主要的食用植物油来源，而且又可提供丰富的植物蛋白质。
花生在制取油脂、制取花生蛋白、生产花生仪器以及在花生贸易出口时，都需要对花生进行预处理加工。
花生的预处理主要包括花生的剥壳和分级、破碎、轧胚和蒸炒等。
花生在加工或作为出口商品时，需要进行剥壳加工。
花生在制取油脂时，剥壳的目的是为了提高出油率，提高毛油和饼粕的质量，利于轧胚等后续工序的进行和皮壳的综合利用。
花生剥壳的原理很多，因此产生了很多种不同的花生剥壳机械。
花生剥壳部件是花生剥壳机的关键工作部件，剥壳部件的技术水平决定了机具作业刚花生仁破碎率、花生果一次剥净率及生产效率等重要的经济指标。
在目前的生产销售中，花生仁破碎率是社会最为关心的主要指标。
花生脱壳机是将花生荚果去掉外壳而得到花生仁的场上作业机械。
由于花生本身的生理特点决定了花生脱壳不能与花生的田间收获一起进行联合作业，而只能在花生荚果的含水率降到一定程度后才能进行脱壳。
随着花生种植业的不断发展，花生手工脱壳已无法满足高效生产的要求，实行脱壳机械化迫在眉睫。
我国花生脱壳机的研制自1965年原八机部下达花生脱壳机的研制课题以来，已有几十种花生脱壳机问世。
只进行单一脱壳功能的花生脱壳机结构简单，价格便宜，以小型家用为主的花生脱壳机在我国一些地区广泛应用，能够完成脱壳、分离、清选和分级功能的较大型花生脱壳机在一些大批量花生加工的企业中应用较为普遍。
刮板式花生去壳机能否正常运转，看的是其主要部件的设计，如果设计不合理，机器就不能正常运转或者说不能运转，那么生产出来的这台机器就是一堆废品。
设计合理，机器就能正常的运转对并对花生果进行剥壳。
因此，刮板式花生去壳机的主要部件的设计在整个设计过程中显得尤为重要，合理的设计将提供给使用者更多的方便和实惠。

Preparation of peanut oil, extraction of peanut protein, peanut production equipment and export trade in peanuts, peanut require pretreatment processing. Peanuts include peanut sheller pretreatment and grading, crushing, rolling, such as embryo and steamed fried. Peanuts during processing or as an export commodity, the need to peel processing. Preparation of peanut oil, the peel is designed to improve the oil yield, increased crude oil and meal quality, conducive to the follow-up processes such as rolling the embryo and the husk of utilization.The principle of a lot of peanut sheller, resulting in a very wide variety of peanut shelling machine. Peanut sheller peanut sheller parts is the key working parts, peel components determines the level of technology equipment operation rate of just crushing peanuts, peanuts and a stripping ratio of net production efficiency and other important economic indicators. In the current production and sales in peanut crushing rate is most concerned about the major social indicators.Peanut shelling machine is to remove the pod peanut shell and get the field operating machinery. Since its physiological characteristics of peanut peanut peanut shelling the field can not be joint operations with the harvest, but only the moisture content in the pod down to a certain extent, be carried out after the shelling. With the continuous development of planting peanuts, peanut shelling by hand have failed to meet the requirements of efficient production, the implementation of mechanical shelling is imminent.Peanut Shelling Machine since 1965 the Ministry issued the original eight peanut shelling machine Machine issue, there have been dozens of peanut shelling machines come out. Function only for a single shelled peanut shelling machine structure is simple, cheap, to small home-based peanut shelling machine widely used in some parts of China, to complete the shelling, separating, cleaning and grading capabilities of the larger peanut sheller peanut processing in a number of high-volume business in more general use.Shelled peanuts scraper machine operating correctly, and read the main parts of the design, if poorly designed, the machine will not operate or can not operate, then the production out of this machine is a pile of waste. Designed, the machine can operate on the normal and the peanut sheller. Therefore, shelled peanuts scraper design of main parts of machine in the whole design process is particularly important, reasonable design will provide users with more convenience and benefits.Key words：Peanut Shelling Peanut shelling machine scraper目录摘要 (Ⅰ)ABSTRACT (Ⅱ)1绪论 (2)1．1研究背景 (2)1．2花生脱壳机械的发展 (2)1．3花生脱壳机械的研究应用现状 (7)1．4花生脱壳机械研究重点 (10)1．5花生脱壳机械应用前景展望 (11)2刮板式花生去壳机的结构及工作原理 (13)2．1刮板式花生去壳机的结构 (13)2．2工作原理 (14)3刮板式花生去壳机主要部件的结构设计 (16)3．1设计前各项参数的确定 (16)3．2V带传动 (19)3．3轴 (22)3．4刮板结构 (25)3．5半栅笼 (26)3．6箱体 (26)3．7壳仁分离装置 (27)3．8机架 (27)3．9附件 (27)4如何正确使用花生脱壳机 (28)5总结 (29)参考文献 (30)致谢 .................................................................................................................. 错误!未定义书签。
1 绪论1．1研究背景花生中富含脂肪和蛋白质，既是主要的食用植物油来源，而且又可提供丰富的植物蛋白质。
利用花生或脱脂后的花生饼粕的蛋白粉，可直接用于焙烤食用，也可作为肉制品、乳制口、糖果和煎炸食品的原料或添加剂。
以花生蛋白粉为原料或添加剂制成的食品，既提高了蛋白质含量，又改善了其功能特性。
花生蛋白粉还可以通过高压膨化制成蛋白肉。
花生是食用植物油工业的重要原料，利用花生油可制造人造奶油、起酥油、色拉油、调和油等，也可用作工业原料。
花生除经简单加工就可食用外，经深加工还可以制成营养丰富，色、香、味俱佳的各种食品和保健品。
花生加工副产品花生壳和花生饼粕等可以综合利用，加工增值，提高经济效益。
花生在制取油脂、制取花生蛋白、生产花生仪器以及在花生贸易出口时，都需要对花生进行预处理加工。
花生的预处理主要包括花生的剥壳和分级、破碎、轧胚和蒸炒等。
