摘要：In order to solve the problem that traditional millet drilling method needs labor-intensive artificial thinning-out, a hole-seeding method is proposed to replace it. Under hole-seeding conditions, an air-suction millet seed-metering device was designed. The design of air-cutting valve can assure that suction-holes are not clogged and reliably falling seeds. Suction-hole structure of the seed-metering device takes chamfer type. The dimension parameter of the chamfer hole is as follows: diameter of 4 mm, chamfer depth of 2.5 mm, fissuriform bottom of suction-hole is 1 mm width, number of holes is 32. The passing rate of hill spacing, repeat-sowing rate, leak-sowing rate and hill formation were analyzed by seed-metering test platform, which meets the precision of millet seed and agronomic requirements.
