In the past, threshing of grain was a hard and exhausting job, and it took a lot of time. In order to change this case, Scotland inventor James Meckel and his son Andrew After a long effort finally developed the first thresher in the late eighteenth Century. This thresher machine is equipped with a wooden frame that rotates on the roller. A narrow belt is installed on the wooden frame. When it rotates, it forms a stream of air, thus blowing away the shell on the wheat. Andrew also gave the machine a flapping device that loosened the shell. The Merkel thresher can be driven by any power source that is easy to find. They chose to use horses to drive the first threshing machine, but soon produced a new type of machine powered by water and steam.

In general, the emergence of the grain sheller greatly saves the farmer’s time and energy, so that farmers can have more time and energy to do other jobs. They can make more money, and will have a better life someday.
穀物脱穀機の動作原理：
穀物が脱穀機に投入された後、脱穀ローラーと凹版からなる脱穀装置が攻撃され、こすれ合い、分離装置の篩穴を通じて穀物が清掃され、ファンと風選の共同作用により穀物が清掃される。
