There is following problem in existing separator: 1. because top, selection by winnowing chamber is enclosed construction, the blowing mouth of blower fan directly connects the air inlet of selection by winnowing chamber, above selection by winnowing chamber body, easily produce vortex with the top position of grading bucket, thus the separating effect of impact to grain; 2. iron filings and the heavier granule foreign of quality of grain the inside cannot be sorted out; 3. the impurity of the lighter weight blowing out from air outlet and dust can pollute air.
Summary of the invention
The purpose of this utility model is to provide a kind of wind separator for grain, and its grain cleanliness factor good to the grading effect of grain, that obtain is high, in addition, can not cause dust pollution to air.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of wind separator for grain, comprise selection by winnowing chamber, blower fan, feed hopper and grading bucket, the front and back end of selection by winnowing chamber is respectively arranged with air inlet and air outlet, and the blowing mouth of described blower fan is connected with the air inlet of selection by winnowing chamber by the air channel of S shape; Described grading bucket is three, and the direction in the bottom of selection by winnowing chamber along air inlet to air outlet sets gradually, and the discharging opening place of described feed hopper is provided with magnetic guide plate.
Preferred: the air inlet place of described selection by winnowing chamber is provided with airflow fence.
Preferred: among three minutes hoppers, between every two adjacent minute hoppers, to be provided with the baffle plate of selecting that can regulate height.
Preferred: three minutes hoppers direction along air inlet to air outlet is heavily mix bucket, sturdy grain bucket and half real grain bucket successively, and the discharging opening of described feed hopper is positioned at the top of heavily assorted bucket.
Aforementioned arbitrary structures can be further preferred: the air outlet place of described selection by winnowing chamber connects discharge pipe, and the end of discharge pipe connects dust bag.
Aforementioned arbitrary structures can be further preferred: one end and the feed hopper of described magnetic guide plate are hinged, and the other end has angle regulator.
The utlity model has following beneficial effect: the wind that the pipeline by S shape blows out blower fan converts the wind of linear flow completely to, avoid at the indoor generation vortex of selection by winnowing, the classification of grain being impacted, the wind of assurance from air inlet to air outlet is all toward a direction linear flow, and obtains better grain selection by winnowing effect; Feed hopper bottom arranges magnetic guide plate, can the iron filings in grain be adsorbed, thereby it is effectively separated in grain.In addition, the airflow fence of air inlet has the effect that regulates wind direction.By adjusting, divide the baffle plate of selecting between hopper, can carry out the grain sorting of variety classes and different quality.Heavily assorted bucket among three hoppers, for carrying out effective separation by the heavier impurity of grain quality.The dust pollution causing in order to eliminate winnowing machine, arranges dust bag by the air outlet in selection by winnowing chamber and effectively solves.Can regulating the discharging opening size of feed hopper of magnetic guide plate, to control the whereabouts amount of grain, avoids whereabouts to measure the excessive selection by winnowing effect that affects.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cutaway view of the present utility model;
Fig. 3 is the enlarged drawing at A place in Fig. 2.
The specific embodiment
As shown in Figure 1 to Figure 3, a kind of wind separator for grain, comprises frame 1, in described frame 1, is provided with selection by winnowing chamber 2, and the front and back end of selection by winnowing chamber 2 is respectively arranged with air inlet and air outlet.Frame 1 is outside equipped with blower fan 4, and the blowing mouth of described blower fan 4 is connected with the air inlet of selection by winnowing chamber 2 by the air channel 10 of S shape, at the air inlet place of selection by winnowing chamber 2, is provided with airflow fence 17, to need to carry out the adjusting of wind direction according to selection by winnowing.The adjusting device of airflow fence 17 is positioned in the frame 1 in 2 outsides, selection by winnowing chamber, and the structure of airflow fence 17 is identical with the airflow fence of existing air-conditioning 17, and those skilled in the art, with reference to this structure, do not repeat them here.
