| 摘要花生虽小，但营养丰富，能为人体补充大量蛋白。日常生活中，花生米可以当作零食，也可以作为主菜的辅料，使菜肴更加美。最重要的是，花生可以压榨成花生油，而花生油油已成为人们日产生活中不可缺少的食用油之一。花生种植业是我国重要的农作物产业之一，在我国，花生种植已形成庞大的产业链，不仅内需大，而且还大量出口外国，是农业经济的重要组成部分。然而，我国的花生种植机械化水平不高，很多部分还需要人力完成，这使得花生种植业的劳动成本偏高，效率偏低，因此提高花生收割的机械化水平已成为目前紧要任务。花生去壳机是集花生去壳，分选，收集等一些列操作的机械装置，它大大的解放了劳动力，但是我国的花生去壳机仍面临着去壳率低，花生仁易损坏的问题，所以研究花生去壳原理，发展花生去壳机的机械结构是解决上述问题所要面临的重要难关。46307 毕业论文关键词:花生去壳机；原理；机械结构 Abstract Peanut is small, but nutritious and can add a large number of human proteins. Daily life, peanuts can be used as a snack or as a main course materials to make food more delicious. The most important thing is, you can press a peanut oil, soybean oil and edible oil has become one of the people living Nissan indispensable. Peanut farming is one of the important crop industry in our country, peanut planting has become a huge industrial chain, not only large domestic demand, but also a large number of foreign exports, it is an important part of the agricultural economy. However, China's peanut planting mechanization level is not high, many parts still need to complete the manpower, which makes the high labor costs of peanut planting, low efficiency, thereby increasing the level of mechanization of peanut harvest has become a critical task. Peanut shell machine is a peanut shell, sorting, collection and some other mechanical device column operations, which greatly liberated the labor force, but the country is still facing machine peanut shell shelled low, peanut easily corrupted Therefore shelled peanut principle, the development of peanut shell machine mechanical structure is an important difficulty to solve the above problems to be faced.
