As limiting deflector: described deflector and horizontal angle are as 30 ° to 60 °.
This utility model additionally provides a kind of grain cleaner air sieve, including the main frame for grain being carried out vibration screening, being provided with at least two-layer in main frame for the sieve screening grain, the surface entering grain end of described main frame is fixed with grain cleaner air sieve fan housing described above.
As limiting main frame: described main frame is the U-shape structure of comprehensive opening as top, described sieve is sequentially arranged at intervals downwards by the top of U-shape structure.
Restriction as to sieve: being provided with first case sieve and the second sieve two-layer sieve altogether in described main frame, the first sieve is fixedly arranged on U-shape structure upper end, and the second sieve is fixed at below the first sieve.
As sieve being further defined that described first sieve and the second sieve are punching sieve.
Owing to have employed above-mentioned technical scheme, compared with prior art, acquired technological progress is this utility model:
(1) this utility model shell is class arcuate structure, the wind of outer fan is having more adsorptivity after class arcuate structure, and class arc shell is provided with the breach being connected with external environment condition, and utilize an opposite shell moveable cover plate to be covered by breach, when air quantity is adjusted by needs, except the rotating speed of blower fan can be regulated, air quantity can also be accurately regulated by the area of regulation cover plate covering breach, the regulation making air quantity is the most accurate, can be prevented effectively from that wind-force is excessive and sucking-off grain, or wind-force is too small cannot the defect of effective sucking-off impurity；
(2) this utility model is provided with deflector in class arc shell, it is possible to the wind direction in housing is carried out effective water conservancy diversion, even the adsorption effect of wind is more preferable；
(3) main frame of the present utility model is set to U-shape structure, makes the comprehensive opening in top of main frame arrange, and the visual field that can make staff when screening grain is relatively sharp, and facilitates the manual remove impurity of staff to operate；
(4) the equal sieve of sieve in main frame of the present utility model uses punching sieve, even if grain grain is stuck at sieve aperture, blowing and the vibration of main frame by blower fan, the most easily make grain grain depart from sieve aperture, and then can effectively prevent grain grain from blocking sieve aperture, make screening effect of the present utility model more preferable.
In sum, this utility model simple in construction, can not only accurately regulate air quantity, provide more convenient operating platform for staff simultaneously, effectively prevent grain from blocking sieve aperture.
This utility model is applicable to the grain cleaner of disposable type.
This utility model is described in further detail below in conjunction with specific embodiment.
