| 摘 要： | 针对我国包衣机普遍存在的包衣成膜低、包衣不均和种子破损率高等问题，结合国家对种子包衣作业的要求，设计了一种新型的基于气流悬浮的种子包衣机。该包衣机通过对上升气流的引入再分配和切向气流的引入，使种子始终处于漂浮旋转的状态，减少运动阻力和种子间的磨损。同时，计量泵定量给药，喷头切向喷药，保证了稳定的药种比。该包衣机可一次性完成包衣、干燥和输送的功能，确保种子包衣的高质量且覆膜均匀不脱落。

| Abstract: | Aiming at problems of low film forming，uneven coating and high rate of seed damage，a new type of seed coating machine based on air suspension was designed according to national requirements for seed coating operation.Through the introduction and redistribution of updraft and tangential airflow，seeds were kept in the state of floating and rotating，resistance of movement and seed wear were reduced.Quantitative dosing of metering pump and tangential spraying of nozzle ensured a stable seed ratio.The coating machine can complete functions of coating，drying and conveying at one time，so as to ensure high quality of seed coating and uniform film coverage. |
