Light miscellaneous exit 37 on 31. The specific gravity blower 5 is arranged below the specific gravity concentrating table 313 .

The sieve holes of the specific gravity concentrating table 313 should be smaller than the grain size, and the sieve holes of the large miscellaneous sieve plate 311 and the small miscellaneous screen board 312 should be larger than the grain size. The specific gravity selection table 313 and the large miscellaneous sieve plate 311 can be conventional ordinary sieve plates, and the pictures are all the existing fish scale hole sieve plates. According to the type of the specific gravity blower 5 , the specific gravity blower 5 of the present invention is also provided with a sawtooth-shaped air-distributing plate 51 to ensure that the wind is evenly blown to the specific gravity selecting table 313 . The air guiding structure may be a pipe.

Among them, the small miscellaneous screen plate 312 can be set horizontally, and the selection machine of the present invention preferably the small miscellaneous screen plate 312 is inclined, so that the light miscellaneous air selection channel 33 is also in an inclined setting state, and the lower end of the light miscellaneous air selection channel 33 is in a state. It communicates with the specific gravity screening channel 34 . In this way, part of the grain can enter the specific gravity screening channel 34 through the sieve holes of the small miscellaneous sieve plate 312, and part can enter the specific gravity screening channel 34 from the lower end of the small miscellaneous sieve plate 312 (light miscellaneous air separation channel 33), and the screening efficiency of grains is high. . The inclination direction of the small impurity screen plate 312 is the same as the inclination direction of the specific gravity concentrating table 313 (the inclination angle may be different), which is convenient to send out impurities.

When in use, the grains enter from the hopper 2 to the large miscellaneous sieve plate 311 of the vibrating screen 3, and the large miscellaneous sieve board 311 screens out the impurities in the grain that are larger in volume than the grain, and the large miscellaneous impurities remain on the large miscellaneous sieve board 311 from the large miscellaneous impurities. The outlet 40 is discharged. After the grains pass through the sieve holes of the large miscellaneous sieve plate 311, they are gathered into the light miscellaneous air separation channel 33 through the material flow structure, and then enter the specific gravity screening channel 34 through the small miscellaneous sieve plate 312. During this process, the airflow generated by the specific gravity blower 5 passes through the sieve holes of the specific gravity concentrating table 313 to blow up the grains on the specific gravity concentrating table 313, and the grains flow out from the second grain outlet 35 under the action of gravity, with a relatively high specific gravity The heavy miscellaneous stones are discharged from the birth port 36 under the vibration of the specific gravity concentrating table 313, and a part of the airflow passing through the specific gravity concentrating table 313 is guided by the air guide structure and then enters the light miscellaneous air selection channel 33, and flows along the light miscellaneous wind. The selection channel 33 flows out from the light-miscellaneous outlet 37, so that the grains entering the light-miscellaneous air-sorting passage 33 can be selected by using this part of the air flow, so as to sort out the light miscellaneous mixed in the grains, so that the sorting machine does not need any more.

As shown in Fig. 2, the sluice structure includes the main sluice plate 321 and the auxiliary slug plate 322 respectively arranged at both ends of the large miscellaneous sieve plate 311. The main sluice plate 321 and the auxiliary sluice plate 322 can be welded on the screen box 31. On the wall, the main feeding plate 321 and the auxiliary feeding plate 322 are arranged in a figure-eight shape, thereby forming a first grain outlet 38 whose extension direction is perpendicular to the extension direction 6 of the light-miscellaneous air selection channel. The extension direction 6 of the light-miscellaneous air selection channel refers to from the connecting end of the light-miscellaneous air-selecting passage 33 and the specific gravity screening passage 34 to the communicating end of the light-miscellaneous air-selection passage 33 and the light miscellaneous outlet 37 . The extension direction of the first grain outlet 38 is perpendicular to the extension direction 6 of the light miscellaneous air selection channel, so that the grains are gathered from the first grain outlet 38 into the light miscellaneous air selection channel 33 from the first grain outlet 38 during the process of entering the light miscellaneous air selection channel. The curtain is convenient for the airflow to sort out the light impurities in the grain.

The grain outlet end of the main feeding plate 321 and the grain outlet end of the auxiliary feeding plate 322 can be set flush. In Figure 2, the grain outlet end of the main feeding plate 321 is lower than the grain outlet end of the auxiliary feeding plate 322 and extends outward, so that The first grain outlet 38 is made to discharge along the direction of wind flow in the light-miscellaneous wind selection channel. This not only facilitates the rapid separation of light impurities from the grains containing impurities under the action of gravity and wind, improves the efficiency of wind separation, and avoids blocking the first grain outlet 38, but also facilitates the discharge of light impurities from the light impurities outlet 37 with the airflow, avoiding airflow. A turbulent flow is formed in the light and miscellaneous wind selection channel 33, which affects the wind selection effect.

As shown in FIG. 2 , the specific gravity screening channel 34 has a top plate 341 whose one end is connected to the grain outlet end of the main feeding plate 321. The top plate 34 is inclined to the air inlet 332 of the light-miscellaneous air selection channel. The top plate 341 constitutes an air guide structure, so that the The lower end surface of the top plate 341 guides the wind. Wherein, the top plate 341 can be welded on the box wall of the screen box 31 .

If only relying on the top plate 341 to guide the wind, the wind flow is mainly concentrated on the upper end of the wind selection channel 33, which makes it difficult to sort out the light impurities. In FIG. 2 , the specific gravity screening channel 34 is also provided with a plurality of air guide plates 39 inclined to the air inlet 332 of the light and miscellaneous air selection channel. The wind selection channels 33 are arranged at intervals in the extending direction. The wind guide surface of the wind guide plate 39 is a concave arc surface, which can reduce the loss of wind energy during the wind guide process. The wind deflector 39 is a plurality of pieces and is arranged at intervals along the extension direction 6 of the light-miscellaneous air selection channel, so that while increasing the air volume for air selection, the wind flow can be introduced into the light-miscellaneous air selection channel 33 in layers through the air guide plate and the top plate. In this way, the air flow in the air selection channel 33 is uniform, and the selection effect of the selection machine is better.

As shown in FIG. 3 , one end of the light-miscellaneous air-selecting channel 33 connected to the light-miscellaneous outlet 37 is the light-miscellaneous air-selecting channel outlet end 331 , and the cross-sectional area of the light-miscellaneous air-selecting channel outlet 331 gradually decreases from the inside to the outside. Small. In this way, the closer to the light impurity outlet 37 in the light impurity air selection channel 33, the stronger the wind force, so that the small impurity sieve plate 312 is not screened by the large impurity sieve plate 311 during the vibration process. Under the synergistic action of the airflow and the small impurities screen plate 312, it is pushed to the light impurities outlet 37, because the closer to the light impurities outlet, the stronger the wind force is, so that these impurities can be separated and blown out, and the air selection effect of the concentrator is better. Similarly, in order to facilitate the discharge of heavier stones and other impurities screened on the specific gravity screening table, the cross-sectional area of the end connecting the specific gravity screening table with the stone outlet gradually decreases from the inside to the outside. 4 , the small miscellaneous sieve plate 312 is a fish scale hole sieve plate, and the fish scale holes 3121 thereof are arranged toward the light miscellaneous outlet 37 . In this way, compared with the ordinary sieve plate, the vibrating separation effect of the fish scale hole sieve plate is better, and it can guide the direction of the wind flow.

The stone outlet 36 is also provided with a stone outlet adjustment baffle 361 for adjusting the opening of the outlet. Specifically, the stone output adjusting baffle 361 is connected with the screen box 31 by bolts, and the bolt holes of the stone output adjusting baffle 361 are strip holes. When the type of grain, the size of the wind flow, etc. change, the outlet opening of the stone outlet 36 is adjusted by the stone outlet adjustment baffle 361 to prevent the airflow from blowing the grain out of the stone outlet 36 .

As shown in FIG. 3 , the vibrating screen 3 also includes a sliding screen 314 that is connected to the second grain outlet 35 . The screen hole of the sliding screen 314 is smaller than the grain size. some impurities. The sieve 314 is inlaid with magnets 315 to sort out iron impurities in the grains.
