Design and Performance Test about Fine and Small Amount Millet Sowing Machine

Focus on solution of problems about lack of special drill for grain growing，a fine and small amount millet sowing machine was designed.Structure design and parameter optimization of core component for metering device and pressing device were carried out.Through experimental design method，seeding effect of operation quality from experimental factors was obtained，and optimal parameter combination was optimized.Practice has proved that experimental design was reasonable，and it had certain practical significance.
