家庭用玉米脱粒机结构设计

家庭用玉米脱粒机结构设计摘要：自1785年由苏格兰人安德鲁·迈克尔安朱梅克研制出世界上最早的旋转式脱谷机后，国内外学者对该设备进行了广泛的实验与研究，并在此基础上研制出了新型的旋转式脱谷机。一八一五年，美国发明了全球首部人工操纵的玉米脱粒器，专门用于打谷子。从那以后，人类就没有停止过对这台设备的改造。国内自主开发的撞击机理型脱粒器在70年代初开始推广使用，当时主要是大中型脱粒器。80年代以来，随着家庭联产承包责任制在农村推广，为了满足农民的需求，我们先后研制出了一系列中、小型玉米脱粒机。伴随着时代的进步，机械化在我国得到了快速的推广。因为我们国家是个农业大国，同时也是我们国家的经济基础。因此，推广机械化在我们国家的发展中起到了非常关键的作用。然而，因为我们国家目前的农业状况，大部分都是小农经济，这就导致了在有些领域中，很难推广到大规模的机器，因此就必须要推广到更多的家庭中去。玉米脱粒机就是一种很好的例子，随着玉米的种植面积越来越大，玉米的脱粒也变成了困扰着人类的一个难题，因为用手去脱粒，不仅速度快，还费时间，还会有很多人去做，非常的不便，但是用手去做，却可以用更少的人力去做，最重要的是，它的工作效率会得到很大的提升，因此，它是农民们必不可少的一种农业机械。玉米去壳之后，晾晒一段时间，再用打谷机将玉米从籽粒中分离出来，这个机器叫做“玉米机”。其工作原理为：在玉米脱粒过程中，采用了一种通过钉齿滚简式旋转的钉子。齿与筛网之间的间隙相互合作，从而让玉米粒被拖下（在钉齿滚简和筛网之间的摩擦作用下，玉米粒与玉米芯被分开，通过其他的机械装置，从两个独立的出口中被排到了机身外面，籽粒被筛孔中被分离出来，玉米芯被从机器尾部排出，玉米丝，皮屑被从风机中排出。一个循环，就是将谷子放进去，然后将谷子放出来，然后再放出来。本产品，脱粒效果取决于辊子的长短及直径，大家可以依据自身的脱粒效果，选择合适的谷物脱粒机。关键词：玉米脱粒机：脱粒结构：设计Structural design of household cornthreshing machineAbstract:Since the world's earliest rotary threshing machine was developed by Scottish manAndrew Michael Anjuemaker in 1785,scholars at home and abroad have conducted extensiveexperiments and research on this equipment,and on this basis,a new type of rotary threshingmachine has been developed.In 1815,the United States invented the world's first manuallyoperated corn thresher,specifically designed for threshing millet.Since then,humans havenever stopped modifying this device.The domestically developed impact mechanism thresherbegan to be promoted and used in the early 1970s,mainly consisting of large andmedium-sized threshers.Since the 1980s,with the promotion of the household contractresponsibility system in rural areas,we have developed a series of small and medium-sizedcorn threshing machine to meet the needs of farmers.With the progress of the times,mechanization has been rapidly promoted in China.Because our country is a majoragricultural country and also the economic foundation of our country.Therefore,promotingmechanization has played a crucial role in the development of our country.However,due tothe current agricultural situation in our country,most of it is a small-scale agriculturaleconomy,which makes it difficult to promote it to large-scale machines in some fields,so it isnecessary to promote it to more households.Threshing machine is a good example.With thegrowing planting area of comn,comn threshing has become a problem that puzzles mankind.Because threshing by hand is not only fast,but also time-consuming,and many people will doit,which is very inconvenient.But it can be done by hand with less manpower.Mostimportantly,its work efficiency will be greatly improved.Therefore,It is an essentialagricultural machinery for farmers.After the corn is hulled,it is dried for a period of time,and then separated from the seedsusing a thresher.This machine is called a "corn machine".Its working principle is that duringthe corn threshing process,a nail that rotates through a toothed drum is used.The gaps between the teeth and the screen mesh cooperate with each other,So that thecorn kernel
