Brought beneficial effect is by adopting the above technical scheme: the plantation side that the present invention passes through the feeding millet of improvement
Method improves the grain weight and germination percentage of seed-grain.The present invention specially devises vibrating screen, in benefit to improve seed-grain screening efficiency
While screening with compass screen surface, lateral purging is carried out to seed-grain using the first compressed air puff prot, makes the impurity of lightweight
It comes together in the first collecting box, and short grained heavier impurity then passes through sieve nest and comes together in the second collecting box.For first
Impurity in collecting box carries out secondary separation to impurity by water tank, can be smaller by the grain being collected into the first collecting box weight
Seed-grain is separated, to be recycled.Second compressed air puff prot is used to carry out the seed-grain on compass screen surface longitudinal purging,
On the one hand it is driven convenient for impurity by lateral purge stream, in addition can increase the frequency of exposure of seed-grain and compass screen surface, accelerate screening
Efficiency.When air flow contacts are to rotary inner core bottom surface, under the action of water conservancy diversion inclined-plane, air-flow pushes rotary inner core rotation, then
It is sprayed by through-hole, so that the variation in jet-impingement direction is realized, to further increase the purging effect to seed-grain.
