家用玉米脱粒机设计 家用玉米脱粒机设计 摘 要 20 世纪 70 年代初，我国发展的纺织机械对纺织机械原理的影响，尤其是在大中型脱粒机上。20 世纪 80 年代，中国农村发展了契约责任制，然后又一系列冲动性原则，在需求小玉米的同时，重新审视农民的需求。随着.的发展，机械化在中国很流行，因为中国是一个伟大的国家，农业被认为是我们经济的基础，所以对我来说，通过农业机械对中国的发展至关重要，但是由于经济中的农业状况，大多数是小农户，而且它已经有人认为，在某些方面，大型机器几乎不扩散，一些小型机器也必须扩散。玉米粉碎机是一个典型的例子，玉米产量是如何不断增加的，谷物将一个钟摆旋入，而一个问题是，人工旋转太慢，花费时间，不得不出现许多人，非常舒适，玉米粉碎机，解决了这个问题，所需工作更少，但最重要的是效率显著提高，Drescher 说玉米农舍，不可缺少，农业机械。 关键词 ： 玉米脱粒机 脱粒结构 设计 0 Abstract In the early 1970s, the influence of textile machinery developed in China on the principle of textile machinery, especially on large and medium threshers. In the 1980s, Chinas rural areas developed contractual responsibility system, and then a series of impulsive principles, while demanding corn, re-examine the needs of farmers. With the development of society, mechanization is very popular in China, because China is a great country and agriculture is considered as the foundation of our economy, so for me, agricultural machinery is very important to Chinas development. But because of the agricultural situation in the economy, most of them are small farmers, and it has been thought that, in some aspects, large machines are almost non-proliferation. Some small machines must also spread. Corn mill is a typical example of how corn production is increasing. The grain turns a pendulum into it. One problem is that manual rotation is too slow and time-consuming. Many people have to appear. Its very comfortable. Corn mill solves this problem. It requires less work, but the most important thing is a significant increase in efficiency. Drescher said that corn farmhouse is indispensable. Less, agricultural machinery.
