1、本科机械毕业设计论文CAD图纸QQ401339828种子拌药机结构设计摘要为了防止病虫对播下种子的危害，同时增加种子抗病虫害的能力和增加适合作物生长的微量元素，当前大量采用种子包衣技术。种子拌药也属于种子包衣的一种，是由种子拌药机完成的。根据目前农业生产的特点，设计种子拌药机，从而适应农业生产。主要完成传动装置，搅拌器，供料系统，供液系统等的设计。此种子拌药机具有搅拌均匀，破碎率小，操作简单且适应性广，成本低的特点。利用搅龙的搅拌旋转和种子与种子之间，种子与搅龙之间的翻转滚动相互摩擦来完成种子的拌药，药
2、剂就粘在种子表面上，经过一定的时间，即可获得符合质量要求的种子。目前在拌种工艺中成熟可靠，且物耗、能耗低、成本也低、故设计螺旋搅龙式拌药机。为了避免损坏种子，提高种子包衣的均匀性搅龙边缘与搅料器的外缘都采用橡胶材料。本次设计主要由以下几步构成：首先，确定拌药机总体设计方案，及种子拌药机主要机构的构造及原理，进行传动方案的比较。之后对传动系统及传动系统零件进行计算。关键词 种子拌药机；螺旋搅龙；拌种III本科机械毕业设计论文CAD图纸QQ401339828SeedMixMedicineDesignAbst
