玉米果穗剥皮机的设计与仿真 摘要 最近各行各业的发展都是很快的，农业上对于机械化的要求也是非常明确的，现在生产的玉米变多，所以将玉米的皮剥掉的劳动量自然也就变大了，要想实现机械化生产农业机械是非常关键的，农产品在市面上的销售怎么样，主要就在于农业机器的质量，还有工作效率是高还是低。我们国家，主要种植玉米的地方在北方，在将玉米摘下来，还有剥皮的时候都是通过人工来进行，工人在进行工作的时候强度是非常大的，效率也不高。要想将这种状况进行改善，这篇设计了一台专门对玉米进行剥皮的机器，这样就可以进行自动化工作了，那么工作效率就变高了，工人的劳动强度就变低很多。 本次设计是在了解和掌握玉米果穗剥皮原理、研究现状及发展趋势的基础上进行的。其主要设计内容有玉米果穗剥皮总体方案及工作原理的确定；对齿轮传动、带传动进行设计与计算；剥皮棍的设计、计算与校核；电动机、键等标准件的选择与确定。最后，通过三维、二维绘图软件完成玉米剥皮整体三维造型、装配图及主要零部件图的绘制等。 本次设计的玉米果穗剥皮机，其结构简单，操作方便，能够在很大程度上减轻工人的劳动强度，为其发展、设计与制造提供一个的帮助。 关键词农业；机械化；玉米果穗；剥皮机；设计 Abstract I
