Keywords:   mini-tuber, pneumatic seed-metering device, physical and mechanical property


. In this paper, The physical and mechanical properties of micro-potato were studied. Included the three-axis size, moisture content, average grain weight, density, and the static and dynamic friction angle with different materials.a vibrating feeding pneumatic disc seed-metering device for mini-tuber was designed. The seed-metering device was made up of metering plate, air chamber, frame and vibrating seed feeding device. The working principle of the pneumatic disc seed-metering device was expounded.
