چکیده
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 established a three-dimensional model to design the spiral groove precision seed-metering device using Pro/Engineer. The movement simulation and clearance were tested between the seeding roller and the shell by mechanism module. According to the analysis results, the defaults of the feed device were modified, so that the model structure was optimized. The simulation results showed that this device is simple and suitable and suitable for the seeding requirements of small grains.
