摘　　要：依据对种子包衣的农艺要求,设计了一种新型种子包衣装置。该装置主要由种子定量供应部分、药剂计量供给部分、种子与药剂混合部分、种子与药剂搅拌输送部分、混合室回转清理部分及提升机送种部分等组成,可一次完成供种、供液、药种混合和搅拌输送等作业。设计的叶轮定量供给装置,避免了因外槽轮槽口深度较小而对大粒种子排量精度影响的问题,保证了料种及时、精确的供给。设计了交错式3段螺旋搅龙输送机构,不但可以保证输送能力,而且可以更好地保护种子。利用离心运动及平抛运动规律设计的阶梯状锥形甩盘,实现了种子在空间上的均匀散开,使种、药混合更加均匀。此外,还设计了与包衣装置相匹配的料种提升装置。According to agronomic requirements of seed coating,a new seed coating device was designed. This device consisted of seeds quantitative supplying,liquids quantitative supplying,seed and liquid mixing,seed and liquid conveying,mixing chamber rotary cleaning and bucket elevator etc. This coating device could finish many operation links such as supplying seed,supplying liquid,mixture and transportation of seed and liquid at one time. Design of impeller quantitative supply device avoided question that effecting displacement accuracy of large seeds because of smaller depth of outer groove wheel notch. A timely and accurate supply of seeds was ensured. Design of staggered three section spiral auger transmission mechanism that not only could ensure delivery capacity,but also could better protect seed. Design of ladder shaped taper swinging disc that using centrifugal movement and horizontal projectile motion,which could achieve seed evenly distributed in space,so that seed and liquid mixture were more uniformly. Moreover,bucket elevator for the seeds to match coating device was designed.
