A kind of screening machine screens structure
The utility model is related to grain processing field, and in particular to a kind of screening machine screens structure.
Grain cleaning equipment is seed processing industry with grain stocking industry than one of indispensable equipment, and grain is in storage
Or need the stone that will be mingled in grain, light miscellaneous, small miscellaneous, big miscellaneous and moldy kernel to screen away before processing, to ensure grain
High-quality degree.Current grain needs to exclusively carry out the work of stone before refiner is entered, and is first carried out on special stone remover
Screening, then enters back into recleaner screen, so by two procedures, can extend process time, influences processing efficiency.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of with the screening machine screening structure for going stone function.
The technical scheme that the utility model is used is：A kind of screening machine screens structure, and it includes material bin and material bin
The dust excluding hood that is connected, it is arranged on below dust excluding hood and goes what stone platform and feeding mouth were connected with the discharging opening for removing stone platform
Screen box；The downside end for removing stone platform is discharging opening, and side high is provided with stone outlet hole, described to remove stone platform near discharging opening
One end and screen box be hinged.
Go to be provided with Shitai County's angle regulator between stone platform and screen box described, it is described to go Shitai County's angular adjustment to fill
Put one end to be hinged with screen box, the other end is hinged with stone platform is removed.
Dedusting airduct is additionally provided with dust excluding hood.
The discharging opening of stone platform is being gone to be provided with discharging pneumatic jig, material enters sieve from after discharging opening discharge through the pneumatic jig that discharges
Case, the discharging pneumatic jig is connected with dedusting airduct.
Good effect of the present utility model is：During material first removes material before screen box is entered, by removing stone platform
Stone, enters back into screen box and is screened, and effectively reduces screen box screening pressure, screening effect is improved, while simple structure, is manufactured into
This is relatively low.Stone platform is gone to be hinged with screen box, screen box vibration drive goes stone Platform Vibration to remove stone, saves electric power resource, reduces processing
Cost.Stone platform is removed with angle regulator, can be easy to adjust platform angle according to actual needs.Stone platform top is gone to be provided with
The dust excluding hood of dedusting airduct is connected, is going to form negative pressure above stone platform, stone effect is gone in raising, while negative pressure is conducive to material point
Layer, improves overall screening effect.Going the discharging opening of stone platform to be provided with discharging pneumatic jig, material carries out second selection by winnowing, sieving
Select effect more preferable.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
In the accompanying drawings, 1- material bins, 2- bulk material plates, 3- dust excluding hoods, 4- dedustings airduct, 5- dedustings cyclone, 6- blower fans, 7-
Stone outlet hole, 8- go stone platform, 9- go Shitai County's angle regulator, 10- discharging openings, 11- discharging pneumatic jig, 12- screen boxs, 13- frames,
The small miscellaneous outlet of 14- vibrating motors, 15-, the big miscellaneous outlets of 16-, the outlet of 17- honest materials, 18- feed boxes.
As shown in Figure 1, the utility model include material bin 1 be connected with material bin 1 dust excluding hood 3, be arranged on dedusting
Stone platform 8 and feeding mouth are removed with the screen box 12 for going the discharging opening 10 of stone platform 8 to be connected below cover 3；The screen box 12 sets
Put in frame 13, described go stone platform 8 to include housing and be arranged on the lip(ped) sieve of enclosure interior, the stone platform 8 that goes
Downside end is discharging opening 10, and side high is provided with stone outlet hole 7, described to remove stone platform 8 near one end of discharging opening 10 and screen box
12 are hinged, and vibrating motor 14 is provided with screen box 12.Bulk material plate 2 is provided with dust excluding hood 3, material enters from material bin 1
During dust excluding hood 3 bulk cargo is carried out through bulk material plate 2.Dust excluding hood 9 is buckled and is going to the top of stone platform 8, and its surrounding passes through canvas etc. and goes
The surrounding connection of stone platform 8, it is ensured that the sealing of dedusting.
Go to be provided with Shitai County's angle regulator 9 between stone platform 8 and screen box 12 described, it is described to go Shitai County's angle to adjust
The one end of regulating device 9 is hinged with screen box 12, and the other end is hinged with the housing of stone platform 8 is removed.It is height to remove Shitai County's angle regulator 9
Adjusting screw or pressure leading screw can also use hydraulic cylinder or cylinder.
Dedusting airduct 4 is additionally provided with dust excluding hood 3, dedusting airduct is connected with dedusting cyclone 5 and blower fan 6.
The discharging opening 10 of stone platform 8 is being gone to be provided with discharging pneumatic jig 11, material is from after the discharge of discharging opening 10 through the pneumatic jig that discharges
11 enter screen box 12, and the discharging pneumatic jig 11 is connected with dedusting airduct 4.
When in use, material enters in dust excluding hood 3 the utility model through material bin 1, and the same of Bulk Grain is carried out by bulk material plate 2
When, the dedusting airduct of top carries out dedusting to material, then falls on stone platform 8, in the presence of stone platform 8 is removed, stone
Motion upwards is discharged from stone outlet hole 7, and rest materials are discharged from discharging opening 10, carries out second selection by winnowing into discharging pneumatic jig 11, so
After fall into screen box 12 and screened, filter out it is small miscellaneous discharged from small miscellaneous outlet 15, it is big it is miscellaneous discharged from big miscellaneous outlet 16, after screening
