Development and experiment of seed metering for grass plot seeder
摘要
Abstract
In order to develop a grass plot seeder,which is suitable for cultivation of fine grass varieties,a seed metering test platform was developed which has a special designed transmission mechanism and a seed cup with an adjustable ring.Several kinds of seeds can be fed by feeding mechanism in feeding cup when seeding shaft as well as distributor cone rotates one complete revolution.Seed motion and the relationship between seed outlet and seed cup were analyzed in this paper.Result of orthogonal experiment showed that the number of sweeper blades was one of the main influencing factors of the variation coefficient of seeding uniformity.When 12 sweeper blades and 9 grooves cone were used in test,the variation coefficient of the Pacesetter's seeding uniformity got to the minimum value 16.46％.This research provides a reference for grass plot seeder's development.关键词
