烟草包衣种子筛
本技术属于种子筛选机
,涉及一种烟草包衣种子筛。
技术介绍
目前我国烟叶种植中一般采用烟草包衣种子来种植,以提高种子的抗逆能力和活力。在烟草包衣种子的生产过程中,要求每个包衣内仅有一粒种子,但由于烟草种子粒径太小,在用包衣机对种子进行包衣时,会出现包衣内含有多粒种子的情况,因此种子生产企业需要对每批包衣种子的单籽粒进行筛选,去除包衣内含有多粒种子的包衣种子。在现有的种子筛选
中,用网筛筛选种子的应用较为普遍,其中与本专利技术最为接近的现有技术是中国专利技术专利公布的一种水稻种子除杂筛选机,申请号:201310226947.X;和一种大粒种子筛选机,申请号:201410634689.3。其工作原理是,在网筛震动和种子自身的重力条件下,不同大小颗粒的种子通过均匀布孔的单层或多层网筛筛孔,大于筛孔的颗粒留在筛面上,小于筛孔的颗粒透过筛孔,从而不同大小级别的种子被分开。这两种筛选机都能筛除杂质,筛分不同大小的种子,但是由于烟草包衣种子为圆形、粒径较小,这两种筛选机结构庞大、复杂,振动幅度较大,都不适合筛选烟草包衣种子。
