Abstract
The utility model discloses a grain winnowing machine, including quick -witted case and fan, the machine incasement has the wind channel, the perpendicular intercommunication in top of wind channel one end has the feeder hopper, wind channel other end level intercommunication has the impurity export, wind channel below intercommunication has the product outlet, the fan is dried and is blown out impurity from the impurity export in to the wind channel along the wind channel axial, be equipped with the pendulum actuating cylinder who transfers aerofoil and drive accent aerofoil around the pivot wobbling in the impurity export, the pivot is located the top and the horizontal vertical wind tunnel of axial of impurity export. In the unchangeable condition of fan air -out flow, transfer the swing of aerofoil can change the size that impurity exported to adjust the wind speed in impurity exit, thereby adapt to the needs of different impurity flows and impurity size.
Description
Technical field
The utility model relates to agricultural mechanical field, particularly a kind of grain fanning-sorting machine.
Background technology
Grain fanning-sorting machine be for by cereal compared with the equipment that light impurity is separated from grain, its principle is according to aerodynamic principle, by the difference of light-heavy material density, lighter impurity is blown out from impurities outlet by blower fan, heavier finished product grain then falls under gravity, thus realizes being separated of grain and impurity.Problems existing is, the impurities outlet size of existing grain fanning-sorting machine is constant, and when blower fan wind speed is constant, the wind speed of impurities outlet is constant, cannot adapt to different impurity flows, also cannot adapt to the impurity of different size simultaneously.
Utility model content
In view of this, the technical problems to be solved in the utility model is to provide a kind of grain fanning-sorting machine, can change the size of impurities outlet according to impurity flow and impurity size.
Grain fanning-sorting machine of the present utility model, comprise cabinet and blower fan, in described cabinet, there is air channel, the upper vertical of one end, described air channel is communicated with feed hopper, described air channel other end level is communicated with impurities outlet, product outlet is communicated with below described air channel, described blower fan is axially dried along air channel and is blown out from impurities outlet by impurity in air channel, be provided with the air regulating board that pivotally swings in described impurities outlet and drive the oscillating cylinder of air regulating board, described pivot is positioned at the top of impurities outlet and axial horizontal vertical air channel.
Further, the horizontal both sides of described air regulating board vertically have chute, also comprise scraper, and the afterbody of described scraper is along slide, and the head of described scraper stretches out outside chute and scraped by the impurity between air regulating board and impurities outlet.
The beneficial effects of the utility model: grain fanning-sorting machine of the present utility model, comprise cabinet and blower fan, in described cabinet, there is air channel, the upper vertical of one end, described air channel is communicated with feed hopper, described air channel other end level is communicated with impurities outlet, product outlet is communicated with below described air channel, described blower fan is axially dried along air channel and is blown out from impurities outlet by impurity in air channel, be provided with the air regulating board that pivotally swings in described impurities outlet and drive the oscillating cylinder of air regulating board, described pivot is positioned at the top of impurities outlet and axial horizontal vertical air channel.In the situation that blower fan air-out flow is constant, the swing of air regulating board can change the size of impurities outlet, thus regulates the wind speed at impurities outlet place, thus adapts to the needs of different impurities flow and impurity size.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is schematic front view of the present utility model;
Fig. 2 is A-A sectional view in Fig. 1;
Fig. 3 is I portion zoomed-in view in Fig. 2.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in detail, as shown in the figure: the grain fanning-sorting machine of the present embodiment, comprise cabinet 1 and blower fan 2, in described cabinet 1, there is air channel 3, the upper vertical of one end, described air channel 3 is communicated with feed hopper 4, described air channel 3 other end level is communicated with impurities outlet 5, product outlet 6 is communicated with below described air channel 3, described blower fan 2 is axially dried along air channel and is blown out from impurities outlet 5 by impurity in air channel, the oscillating cylinder 9 of pivotally 7 air regulating boards swung 8 and driving air regulating board 8 is provided with in described impurities outlet 5, described pivot 7 is positioned at the top of impurities outlet 5 and axial horizontal vertical air channel.Cereal enters in air channel 3 from feed hopper 4, and blower fan 2 is dried in air channel 3, and lighter impurity such as husk etc. is blowed to impurities outlet 5 by wind-force, and heavier grain then falls to product outlet 6 under gravity.Because the air regulating board 8 at impurities outlet 6 place can swing up and down, thus the opening size size of adjustment impurities outlet 5, thus regulate the wind speed at impurities outlet place, thus adapt to the needs of different impurities flow and impurity size.
Owing to leaving gap between air regulating board 8 two ends and impurities outlet 5, the impurity such as straw can be stuck between air regulating board 8 and impurities outlet 5, and then affect the swing of air regulating board 8.For this reason, the horizontal both sides of air regulating board 8 vertically have chute 10, also comprise scraper 11, the afterbody of scraper 11 slides along chute 10, and the head of scraper 11 stretches out outside chute 10, when scraper is along slide, the impurity between air regulating board 8 and impurities outlet 5 can scrape by the head of scraper 11, avoids air regulating board 8 stuck by impurity.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
