气吸式排种器种子吸附过程的动力学分析

摘要：分析了气吸滚筒式排种器种子吸附过程的动力学特性，建立了吸附力 F 与滚筒转速ω、

率随着ω的增大而降低，随着α的增加呈现先增大后减小的规律，当ω＝10r/min、α＝30º

时，单粒吸种率达到 94%。 10

performance were received and an adsorption judgment was proposed. Taking rape seeds as

experimental material, sucking performance tests of precision seeder were carried out on the

test-bed. The results show that the seeds single pickup ratio decreases with the increasing ω, the
