2、将一个钟摆旋入，而一个问题是，人工旋转太慢，花费时间，不得不消失很多人，特别舒适，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，不行缺少，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,

3、 China"s 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 consid

4、ered as the foundation of our economy, so for me, agricultural machinery is very important to China"s 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

5、. 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. It"s very comfortable. Corn mill solves this problem.

6、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.
