摘　　要：地膜覆盖播种技术依赖于精密穴播机。甘肃省地处西北丘陵山区,大型农业机械作业困难,而小型农机发展相对不足,迫切需要适用于山区小地块播种的小型精密穴播机。因此,设计了一种手推式小型精密穴播机。该播种机采用外置式种箱和窝眼轮式精量排种器,能够有效避免种子拥堵和精量播种;采用齿轮传动,排种器排种和鸭嘴开启同步进行。田间试验结果表明:播种机播种深度合理,空穴率、穴粒数合格率等均合格,满足作物播种农艺要求。Seeding technology of plastic mulching depends on precision hill-seeders. Gansu Province is located in northwest hilly areas, where it is difficult to operate large agricultural machines, while the development of small agricultural machines is insufficient. It’s urgent for small precision hill-seeders suitable for planting on small plots of mountain. Therefore, a manumotive type small precision planter is designed. It uses external seed box and nest eye wheel precision seed metering device, can effectively avoid seeds congestion and conduct precision seeding. It also uses gear transmission, with seed metering device and duckbill mouth opening simultaneously. The results of field experiments show that the sowing depth of seeder is reasonable, the hole rate and the number of points pass rate are qualified, which meet the requirement of crop sowing.
