After qualified seed of particle diameter flowed into second collection frame 3, because the seed of some ghost, because the particle diameter is enough big and not screened, so toward second collection frame 3 water injection this moment, the unqualified seed of ghost floats at the surface of water owing to the buoyancy that receives water, when the horizontal plane surpassed delivery port 32, along with rivers through delivery port 32 fall into third collection frame 30 in, and fall on second sieve 31, water is discharged through second outlet pipe 33, at this in-process, accessible spout 26 slip scraper blade 27, further scrape out delivery port 32 with the levitated unqualified seed in upper strata, further improved screening effect. After the screening is completed, the water valve 29 is opened, the water in the second collection frame 3 is discharged through the first water outlet pipe 28, and the seeds are left in the second collection frame 3 due to the effect of the first sieve plate 25.
As shown in fig. 5 and 6, the seed screening apparatus mechanism for agricultural production further includes a cover plate 34, a screw 37 and a turntable 38; the cover plate 34 is hinged to the top of the separating cylinder 7 and used for shielding a feeding hole formed in the top of the separating cylinder 7; one side of the cover plate 34 is provided with a second threaded hole 36, a screw 37 is in threaded connection with the second threaded hole 36, the top end of the screw is fixedly connected with the rotary disc 38, and the bottom end of the screw penetrates through the second threaded hole 36 and is in threaded connection with a first threaded hole 35 formed in the top of the separating cylinder 7.
When seeds need to be screened, the cover plate 34 is modified, and the turnplate 38 is screwed to drive the screw rod 37 to rotate, so that the screw rod 37 is screwed into the first threaded hole 35, and the cover plate 34 is fixed to prevent the damage caused by swinging in the rotating process of the separating cylinder 7; the cover plate 34 covers the top of the separating cylinder 7 to prevent seeds from being thrown out of the separating cylinder 7, so that seed loss is avoided.
As shown in fig. 7, the seed screening apparatus mechanism for agricultural production further includes a handle 39; a handle 39 is secured to the top of the blade 27.
When unqualified seeds on the water surface need to be scraped by the scraper 27, the scraper 27 can be slid more conveniently and more easily through the handle 39.
As shown in fig. 8, the seed screening apparatus mechanism for agricultural production further includes a third screen deck 40; the third screen plate 40 is fixed in the second collecting frame 3 and is located above the first screen plate 25.
After falling into second collection frame 3 when the qualified seed of particle size, at first fall on third sieve 40, because the mesh diameter ratio of third sieve 40 is bigger than first sieve 25, so sieve the seed once more, improved the screening effect.
Wherein, the bottom of the separating cylinder 7 inclines towards the direction of the first baffle plate 12; the seeds can flow out from the separating cylinder 7 more conveniently, and the collection is convenient.
