Abstract Aimed at lack of automated assembly line in the domestic vegetable seedling production field, combined with the seeding process of domestic vegetable seeds, the air-aspiration drum type tray precision seeding streamline was designed. The assembly line included an unpowered pressure hole device, a drum-inlaid convex suction nozzle, and a seeding machine for conveying and drum synchronous transmission. The data of air-aspiration drum type tray precision seeding steamline was showed as follows: seeding precision of 98%, seeding cavity rate of 0.6%, productivity of 580 disks/h, seeding amount of 145 disks/(kW·h), and seed breakage rate of 0.4%. The above data shows that the technical indicators of the streamline meet the standards, and the design is reasonable and reliable, which can satisfy
the needs of the actual use of the streamline.

气吸滚筒式穴盘精量播种流水线设计
针对国内蔬菜育苗生产领域缺乏自动化流水线的问题，结合国内蔬菜种子的播种工艺，设计了气吸滚筒式穴盘精量播种流水线。该流水线包括无动力压穴装置、滚筒镶嵌式凸型吸嘴、输送与滚筒同步传动的种子精播机等机构。设计的气吸滚筒式穴盘精量播种流水线检测数据为：播种精度98%，播种空穴率0.6%，生产率580 盘/h，播种量145 盘/（kW·h），种子破碎率0.4%。上述结果表明，流水线的技术指标符合标准，设计合理可靠，能够满足流水线实际使用的需求。
