吸吹式水稻精量播种装置的设计

The Design of the Rice Aspiration Precision Seeder

针对当前水稻播种机的播种装置存在一定程度的伤种、重播、漏播、堵孔以及种子间距难以控制等问题,设计了吸吹式精量播种装置;介绍了其结构和工作原理,给出了工作参数和主要零件结构参数,为育秧盘的机械化精量播种打下了基础。

A rice aspiration precision seeder was designed to solve the existing problems on current seeders,such as hurting seed,re-seeding,omission,blocking and uncontrollable gap between each row.The structure and the operating principle of this new seeder were introduced,also the working parameter and the structural parameters of the major parts were provided in this thesis.It will lay the foundation for the mechanized precision seeding of the seedling nursing tray.
