Description

Seed screener

Technical field

This utility model is related to agricultural machining apparatus field, more particularly to a kind of seed screener.

Background technology

At present, when the seed to crops is chosen seeds, the mode for manually sorting is typically with, such as will be multiple The different handss screen banks of mesh number is combined, and sieves the impurity such as the fine sand adulterated in seed, rubble, soil by hand sieve nest Remove, be classified out the arable seed of full grains.And this screening mode not only easily causes the fine sand, broken for screening The impurity such as stone, soil are arbitrarily scattered, and the dust contained in impurity is flown away to environment, and increased human cost, Waste time and energy.Although prior art also has being sorted to seed using special screening machine, existing screening machine price is held high Expensive, noise is big, the quality of sorting seed does not reach standard yet, it is difficult to meet actual demand.

Content of the invention

In view of this, the purpose of this utility model is to provide a kind of seed screener, not only can achieve the two-stage of seed Rapid screening, reduces operator's labor intensity, it is ensured that the quality of screening seed, and can avoid to environment, can Realize quickly discharging.

Seed screener of the present utility model, including casing and the case lid being arranged on casing, is provided with the casing Primary filter plate and cascade filtration plate, the primary filter plate and cascade filtration plate are inclined in casing respectively, described first The two ends of level screen plate are fixed on case lid bottom by support bar respectively, and are vacantly located in casing, the cascade filtration plate position Below primary filter plate, cascade filtration plate hight end is located at below primary filter plate low side, and cascade filtration plate low side is located at primary The high-end lower section of screen plate, is provided with feed hopper and dust removal port on the case lid, the feed hopper is located on primary filter plate hight end Side, is provided with dust extraction fan in the dust removal port, is respectively equipped with the first discharging opening and the second discharging opening on the box bilateral wall, First discharging opening is located at primary filter plate lower end, and the second discharging opening is located at cascade filtration plate lower end, the casing bottom Portion is tapered portion wide at the top and narrow at the bottom, and the tapered portion lower end is provided with discharge gate, and tapered portion bottom is provided with support feet.

Further, the case lid may be detachably retained at casing top.

Further, the primary filter plate end is symmetrically arranged on two with support bar, and the support bar lower end is weldingly fixed on On primary filter plate, upper end may be detachably retained at case lid bottom.

Further, the cascade filtration plate two ends are fixed by screws on the corresponding side wall of casing respectively.

The beneficial effects of the utility model：Seed screener of the present utility model, by arranging the primary filter plate for inclining With cascade filtration plate, the seed containing impurity is entered after casing through feed hopper, primary mistake can be carried out by primary filter plate first Filter, and by primary filter after seed discharged by first outlet material, then fine straining is carried out by cascade filtration plate, and by fine straining after Seed is discharged by second outlet material, and the impurity such as fine sand, rubble, soil in seed is fallen directly in the tapered portion of casing, by Discharge gate is discharged；Simultaneously by arranging dust removal port and dust extraction fan, the dust produced in screening process is enable to be discharged into and remove In the dust arrester of dirt fan connection, it is to avoid to environment, so as to not only can achieve the two-stage rapid screening of seed, drop Low operator's labor intensity, it is ensured that the quality of screening seed, and can avoid to environment, can achieve quickly to go out Material.

Description of the drawings

With reference to the accompanying drawings and examples this utility model is further described：
