Grain counters and threshers are agricultural machinery and equipment used in the processing and harvesting of crops. Their main role is to help farmers improve productivity and reduce labour intensity. Although both are agricultural machinery and equipment, their functions and working principles are very different.

Grain counting machines are mainly used for cleaning and sorting impurities and bad grains in crops, such as beans and grains. Grain counting machine usually consists of conveying department, cleaning department, sorting department and electric control system. Firstly, through the action of the conveying section, the crops with impurities and bad grains are fed into the cleaning section of the counting machine. The cleaning section removes the impurities and dust from the surface of the crop by means of water rinsing to make it cleaner and more hygienic. Next, the cleaned crop will be fed into the sorting section, where the impurities, broken and substandard crops will be separated by mechanical vibration and airflow, leaving only the good quality crops. The sorted crop will be sent out of the machine to complete the whole process of grain counting.

The threshing machine is mainly used for harvesting mature grain crops, such as wheat, rice, corn and so on. The threshing machine usually consists of conveying section, threshing section, sorting section and electric control system. Firstly, the mature grains are collected and fed into the threshing section through the action of the conveying section. The threshing section crushes and separates the grain skins or husks by mechanical or power means to obtain better quality grains. Next, the threshed grains will be fed into the sorting section, where the crumbs and impurities will be separated out by mechanical vibration and airflow, leaving only clean grains. , The sorted grain will be sent out of the machine, completing the whole process of threshing.

From the above description, it can be seen that the difference between grain counting machine and threshing machine is mainly reflected in the function and working principle. Grain counting machines are mainly used for cleaning and sorting impurities and bad grains, while threshing machines are mainly used for harvesting and threshing grains. Grain counting machine completes the processing of crops through cleaning and sorting, while the threshing machine completes the processing of grains through threshing and sorting. In addition, the counting machine and threshing machine are different in structure, in which the counting machine pays more attention to cleaning and hygiene, and the threshing machine pays more attention to production efficiency and output quality.

In practical application, grain counting machine and threshing machine are indispensable agricultural machinery and equipment for farmers. Through reasonable selection and use, they can effectively improve production efficiency, reduce labour intensity, and improve the quality and yield of crops. Therefore, in agricultural production, grain counting machine and threshing machine both play an important role, for the farmers have a positive role in promoting the production of life.
