Embodiment
Illustrate present disclosure below in conjunction with specific embodiments.
As shown in figure 1, the invention provides a kind of structural representation of intelligent environment protection wind-force grain selecting machine, including screening
Case 10, dust arrester and screening storehouse 20；Dust arrester is located at the side of screen box 10, and screen box 10 and dust arrester are respectively positioned on sieve
Divide the top in storehouse 20.
As shown in Figure 1, Figure 2, Figure 3 shows, the upper end of screen box 10 is provided with feed hopper 11, and the lower section of feed hopper 11 is provided with
Waterfall type dissipates ware 12, and screen box 10 is internally provided with negative pressure cavity 14, and the negative pressure cavity 14 passes through suddenly change air-flow velocity or gas
Direction is flowed, makes the material separation of different weight miscellaneous to eliminate the weight in grain, such as blinding, enables blinding gravitational settling,
So as to discharge screen box 10, negative-pressure air fan 15 is provided with negative pressure cavity 14, negative-pressure air fan 15 is used to change the gas in negative pressure cavity 14
Flowing flow velocity or airflow direction so that grain particle, unsound grain and barnyard grass can move with airflow direction, and then directly
Heavier blinding is separated, and for blinding, lighter cereal-granules, unsound grain and barnyard grass can timely enter
Sieved in screening storehouse, negative-pressure air fan 15 controls rotating speed by respective controller, and negative-pressure air fan 15 is used for unexpected
Change the air-flow velocity or airflow direction in negative pressure cavity 14, only need a negative-pressure air fan 15 to can be achieved to efficiently separate blinding,
And enable grain particle, unsound grain and barnyard grass as airflow direction moves, the lower end of screen box 10 and it is located at
The scattered ware 12 of waterfall type is arranged right below the first discharging opening 17, is fixedly connected, sieves between the first discharging opening 17 and screen box 10
Select the lower end of case 10 and be provided with the second discharging opening 18 at negative-pressure air fan 15, it is fixed between the second discharging opening 18 and screen box 10 to connect

The separation such as the blinding of weight, corn particle, light impurity, unsound grain, the relatively large blinding of weight directly drop into first
Discharging opening 17, and depart from intelligent environment protection wind-force grain selecting machine, full cereal-granules from the first discharging opening 17（Such as corn）, it is light
Impurity, unsound grain etc. drop into the second discharging opening 18 under negative pressure and cross-ventilated effect, as shown in Fig. 2 raw grain is unscreened
The cereal-granules divided（Such as corn）, represented with a, blinding is represented with b, corn particle, light impurity barnyard grass and unsound grain it is mixed
Compound represents that the direction of arrow represents the respective direction of motion with c, and a is fallen from feed hopper 11, and b and c, b are divided into negative pressure cavity 14
Depart from from the first discharging opening 17, c drops into the second discharging opening 18 under negative pressure and cross-ventilated effect, so that foodstuff grain
In heavy seeds, such as blinding, greatly reduce, the probability containing grain is greatly reduced in impurity, improve the miscellaneous clearly yield of grain and
Impurity-eliminating effect, while also avoid blinding from being directly entered screening storehouse 20 and cause the mill of the inside spin of screening storehouse 20 propulsion screen drum 24
Damage；The air inlet of negative-pressure air fan 15 is provided with ventilative barrier film 151, for preventing corn particle, light impurity barnyard grass, unsound grain
Cause negative-pressure air fan 15 to damage in into negative-pressure air fan 15, and then ensure that negative-pressure air fan 15 being capable of normal operation and impurities removal.
As Figure 1 and Figure 4, the dust arrester includes blower fan 30 and dedusting separating mechanism 40, and described blower fan 30 enters
