Description
Technical field
The utility model belongs to screening installation technical field, and in particular to a kind of wheat seed screening machine.
Background technology
Wheat is a kind of grass planted extensively in the whole world, and the caryopsis of wheat is one of staple food of the mankind, mill
At the foods such as bread, steamed bun, biscuit, noodles can be made after flour；It can be made into beer, alcohol, white wine or biomass fuel after fermentation
Material.Wheat is rich in starch, protein, fat, minerals, calcium, iron, thiamine, riboflavin, niacin, vitamin A and vitamin C
Deng；Wheat is one of three big cereal, is almost eaten entirely, is only used as feed there are about 1/6th.The Yellow Basin and the Yangtze River is the world
The area of upper earliest cultivated wheat, China is one of the country that wheat is planted in the world earliest.
The genetic stability of wheat is higher, can directly reserve seed for planting, and the wheat routinely harvested is in harvesting and dryness in the sun process
In can be mixed into impurity, therefore screened when reserving seed for planting, screening process can remove shrivelled cur, stalk, the awn of wheat and
The impurity such as rubble improve the breeding rate reserved seed for planting and germination percentage.Current screening wheat generally use wind turbine is screened, this sieve
Select mode that can only remove the impurity such as the awn of wheat, stalk in seed；In addition it can use color selector to be screened, the sieve of color selector
Select effect good, the germplasm character after screening is outstanding, but the manufacturing of color selector and use cost are very high, is not suitable for small
Type enterprise uses.
Utility model content
For the defects in the prior art, the purpose of this utility model is to provide a kind of wheat seed screening machine.The screening
Machine structure is relatively easy, and production cost is low, but good for the screening effect of wheat seed, can be precisely separating out underproof
Seed and various impurity.
The technical solution of the utility model is：A kind of wheat seed screening machine, including feeding warehouse and reserve seed for planting storehouse, under feeding warehouse
Fang Liantong discharge gates, discharge gate is elongated, and setting is multiple in discharge gate is below discharging channel arranged in a straight line, discharge gate
Clean storehouse, and the side setting removal of impurities air blower inside the storehouse that cleans, removal of impurities air blower wind direction is horizontal direction, and the air blower that cleans goes out
Air port width is more than width of discharge opening, and the position opposite with removal of impurities air blower is equipped with impurity discharging port, impurities removal mouth width on the silo wall that cleans
Degree is more than air outlet width, and outside the storehouse that cleans the landing channel of setting diagonally downward, slides channel and connects with impurity discharging port；The removal of impurities

Receiving hopper is arranged in side, the first vibrating screen lower section, and receiving hopper back cut diameter is more than lower port diameter, and the lower section setting second of receiving hopper is shaken
Dynamic sieve, the sieve bottom of the second vibrating screen is V-shaped, is located in sorting bin on one side, and another side is located in storehouse of reserving seed for planting, and is located in sorting bin
Sieve pore is arranged on bottom in half sieve, and sieve pore is not arranged on the sieve bottom in storehouse of reserving seed for planting；Setting sorting air blast above second vibrating screen
Machine, the wind direction for sorting air blower blow to storehouse of reserving seed for planting by vibrating screen.Wherein, the screen size at the first Vibration Screen bottom is more than wheat
The screen size of wheat size, the second Vibration Screen bottom is less than wheat wheat size.
The process of the screening of the utility model is as follows：Wheat wheat to be screened is sent in feeding warehouse, by discharge gate
It dropping into removal of impurities storehouse, the state that wheat is fallen in discharge gate is in waterfall shape, then under the action of cleaning air blower, the awn of wheat,
Stalk, light impurities and shrivelled cur's are blown at impurity discharging port, and along channel discharge is slid, remaining seed and heavy are miscellaneous
Matter can drop into the first vibrating screen in sorting bin, and the sieve pore of the first vibrating screen is larger, therefore the weight of wheat and small volume
Matter impurity can be fallen on after the screening of the first vibrating screen below the first vibrating screen, and the larger heavy impurity of volume is sifted out, then
The heavy impurity of wheat and small volume under sieve is dropped by receiving hopper in the second vibrating screen, due to the spy of the second vibrating screen
Different structure, in vibration, heavy impurity can drop into the second vibrating screen bottom, and then the part sieve bottom out of sorting bin leaks out,
Wheat in second vibrating screen is blown away by sorting air blower, is dropped into and is reserved seed for planting in storehouse, after the above four screenings program, wheat
In the impurity such as stone, the awn of wheat, stalk, shrivelled cur's be sized away, leave the seed of full health.
In the utility model, removal of impurities air blower and the wind speed for sorting air blower are adjusted by air compressor control device；
By adjusting clean air blower and sort air blower wind speed, can make the screening machine to different moisture content wheat and it is different at
The impurity divided can show outstanding screening effect.
Preferably, the first vibrating screen and the second vibrating screen it is suitable for reading setting it is anti-overflow deliver for sale, the second vibrating screen it is anti-spilled
Field is in storehouse part of reserving seed for planting containing jagged.
In the utility model, anti-overflow on the first vibrating screen and the second vibrating screen is delivered for sale, can be to the wheat in vibrating screen
Blocking is formed, prevents in vibration processes wheat from the spilling suitable for reading of vibrating screen.
Preferably, feeding warehouse is infundibulate storehouse, and bottom size is less than size suitable for reading；It slides channel tail end and impurity is set
Collecting vessel.
In the utility model, feeding warehouse can store a large amount of wheats, be then uniformly discharged by discharge gate, complete wheat sieve
Choosing, the shrivelled wheat and light impurities of blowout can be recycled by sliding the impurity collecting vessel of channel tail end, therein shrivelled
Although wheat is not suitable as seed, but still may be used as the grain of bird feed, can prevent from causing grain after recycling
Waste.
A kind of wheat seed screening machine provided by the utility model has the advantages that compared with prior art：
The screening machine is simple in structure, and manufacturing cost and use cost are relatively low, can reduce seeds company's equipment purchase at
This, has higher economic value；The screening machine is very outstanding to the screening effect of wheat seed, can will be a variety of different miscellaneous
Matter and underproof screen for seeds branch away, and obtain the full wheat seed of health, and the wide adaptability of equipment can also be applied to not
It with the screening of water content seed, and can be recycled to screening out the unqualified seed come, avoid causing to waste.
