为了确定排种器轴转速和机组工作速度之间的最佳匹配关系，对排种器进行了台架试验和理论分析，也对挡种梳进行了改进设计。台架试验和田间考核表明，使用改进后的挡种梳可以显著地减少排种器阻力并且无堵塞现象
In order to determine the best matching relationship between the speed of the seed metering device and the operating speed of the unit, bench tests and theoretical analysis of the seed metering device were also conducted. Bench tests and field tests showed that using the improved baffling comb can significantly reduce the resistance of the seeder without clogging
