摘要
基于高粱种子特性及对播种技术的要求,优化设计了一种勺轮式高粱精量排种器的勺轮盘,通过理论计算与分析确定了高粱勺轮盘的结构和关键参数,并通过田间试验验证了其播种性能。结果表明:排种器播种高粱完全可以实现单粒精播,播深合格率90.67%,株距27~34cm,出苗率87%,漏播率5.7%,满足高粱精密播种的相关国家标准,为高粱机械化播种奠定了基础。
Based on the characteristics of sorghum seeds and the requirements of seeding technology,this paper optimized the design of a spoon-wheel sorghum precision seed metering device.Through theoretical calculation and analysis,the structure and key parameters of sorghum spoon-wheel were determined,and its seeding performance was verified by field experiments.The results showed that the seed metering device could realize single seed fine sowing of sorghum,in which the qualified rate of seeding depth was 90.67%,the plant spacing was 27-34cm,the seedling emergence rate was 87%,and the missed sowing rate was 5.7%,which met the relevant national standards of sorghum precision seeding and laid a foundation for the mechanization of sorghum seeding.
