Improvement for corn threshing device after people have never stopped. The early 7039。s selfdeveloped impact principle of corn threshing machine is widely used in large, medium, when threshing machine. After entering 80 age, rural began to implement the household contract responsibility system, our country has developed a series of impact principle, small corn thresher, in order to meet the production needs of farmers. With the development of society, the mechanization in China spread very quickly, because China is a big agricultural country and agriculture is the economic foundation of our country, so the application of mechanized is crucial for the development of our agriculture, but the agricultural current situation of our country, mostly belonging to the smallscale peasant economy, so the decision in some aspects. Large machinery is difficult to popularize, so need to popularize some small household machinery. Corn threshing machine which is a very typical example, along with the people of the maize yield increase, corn threshing became a priority in an issue that people first, manual threshing too slow, timeconsuming, and requires a lot of people, very inconvenient, corn threshing machine, to solve the a problem, need less labor, and is mainly the work efficiency is greatly improved, so the corn thresher is essential for an agricultural farm. The corn thresher is corn peeling, after drying for a period of time, then the use of corn thresher for corn and corn cob separately, this machine is the corn threshing machine. Its working principle is: corn thresher for corn threshing, the gap between tooth and nail screen tooth cylinder rotary motion of the match, the corn grain down (between the nail tooth roller and a screen kneading action, the corn grain from corn cob, I Suke and other mechanical corn and corn cob respectively from two different outlet outside a machine body, separated by the sieve grain, corn cob discharging machine tail, from corn silk, dander from outlet. Circular threshing, the threshing fill discharge the body of the loop. This kind of machine, the threshing efficiency by the drum length and diameter is determined according to the threshing efficiency, people can own, corn thresher, the reasonable selection of appropriate.Key wordcorn sheller；Threshing structure；design 目 錄1. 引言……………………………………………… 32. 玉米脫粒機(jī)的總體結(jié)構(gòu)的設(shè)計(jì)………………… 5 …………………… 5 ……………………… 63. 電動(dòng)機(jī)的選擇………………………………………7 ………………………………… 7 ……………………… 7 ………………………………… 8 ………………8 ……………………8 …………………
