摘要：In order to realize the mechanized planting of cyperus esculentus, reduce its labor input and meet precision sowing requirement, a precision air suction cyperus esculentus seed-metering device was to be developed. Physical characteristics of the cyperus esculentus seeds was to be calculated and analyed. Through calculation and test, diameter of seed discharge plate, numbers of seed suction opening and shape and diameter of the seed suction opening was determined. It designs a mixing device installed on the discharge plate, through the orthogonal experiment it gets the best geometric dimensioning of the mixing device: height is 5 mm and breadth is 3 mm. Through comparison testing that whether there is the mixing device or not on the discharge plate, it determines that the mixing device with the discharge plate has the best seeding performance when the seed suction opening diameter is 6.5 mm.
