The Study on Mechanical Precise Seed-metering Device Experiment for Tobacco Seedlings
摘要
Abstract
On the basis of analyzing the structure and working principle of disc-type hole mechanical precision seed-me-tering device , discussing the feed wheel structure parameters when seed falling upon and seeding , and this article deter-mined the movement of seeds in the seed tray .In order to explore performance and accuracy of the mechanical tobacco seedling precision seed-metering device, it experimented on seed-metering device, regarding acceptable quality rate, over sowing rate , drain sowing rate , seed breakage rate , coefficient variation in rows , coefficient variation with seed spacing as evaluation , and regarding the two factors of feed wheel speed and distance from seeding mouth to the conveyor belt as variable .The test results show that the evaluations of metering device are acceptable quality rate 48 .61%, over sowing rate 31.94%, drain sowing rate 19.45%, coefficient variation in rows 1.68%, coefficient variation with seed spacing 3 .28%,with the conditions of the feed wheel speed n=8 r/min and the distance from seeding mouth to the con-veyor belt H=50mm.关键词
