[0002] With the rapid development of electronic technology, electronic automation has become a new stage in the development of automation. Electronic automation uses technologies such as integrated circuits, sensors and computers to achieve more precise and intelligent control of equipment and systems. In the agricultural production process, after the collected grains are dried, the work of husking and removing impurities is always indispensable. Rice mills will be used for husking. During the husking process, on traditional rice mills, it is necessary to manually control the switch of the feed hopper gate. Sometimes the gate is pulled too large and the material is discharged quickly, which will cause the machine to jam or affect the husking quality of the rice mill. Sometimes the gate is pulled too small, which will cause slow material discharge and affect the husking efficiency. It not only wastes electricity but also wastes time. Therefore, how to effectively control the gate of the rice mill feed hopper has become a problem that we need to solve urgently. Utility Model Content
