At present, most of small grain crops such as millet and forage seeds are sown by external force feed in mainland China, which has some problems of wasting seeds, uneven seed distribution and so on. Therefore, it is needed to design a precise feed device for small grain corps. The author's of this paper seed-metering device using Pro/Engineer. The movement simulation and module. According to the analysis results, the defaults of the feed device were showed that this device is simple and suitable and suitable for the seeding requirements of small grains.
