摘要 减轻人工坚果破壳的工作量繁重、人工成本高的麻烦是我此设计的最终目的用破壳机代替人工来节约破壳成本和提高工厂的效益。因为坚果种类繁多，这里我选用榛子来作为研究对象。开发深加工技术,拓宽榛子利用方法是提高榛子商品价值的主要途径,而解决这一问题的前提条件就是对榛子进行去壳。榛子剥壳机的设计是我本次的审计题目,以前人们的剥壳方法都是通过用手去剥的，这种方法剥出来的榛子仁虽然质量比较高但是生产率比较低，但我设计出来的这款剥壳机,榛子得主动剥壳可以得到实现,面且和人工用手剥壳相比,生产效率得到了大大提升。然而该产品与发达国家的榛子剥壳机相比,还是有很大的差距的,所以设计出新型的榛子剥壳机是比较迫切的事。 关键词：坚果破壳机，结构设计 Abstract It is the ultimate purpose of our desig
