The Design of Negative-Pressure Precision Millet Seed-Metering Device

In order to solve the millet sowing labour, improve the accuracy of sowing and seeding efficiency, reduce the leakage sowing rate, this paper presents a negative pressure precision millet seed-metering device with adjustable disc gap. Each set of seeding device is composed of two discs, can adjust the gap to meet the requirements of different seed amount. The millet seedmetering according to the requirements of sowing and achieve the required seeding rate, row spacing and plant spacing, saving a large amount of seed, increase the utilization rate of the seeds, ensure production, fully meet the demand for Chinese farmers. The structure and the arrangement of the seed-metering device was optimized, and can be adjusted according to the actual requirements. Also takes into account the economic savings, take discharge device and a furrow opener together, reduce the complexity, and the seeding effect is not affected. So as to achieve the purpose of the design of the seeding machine to achieve the desired.
