There is threaded hole 34, wing bolt 35 is spirally connected with threaded hole 34.
The cereal screened will be needed to pour into screening frame 4 by feed hopper 20, cereal first passes through the second web plate 19 to downslide
Dynamic, the gravel or not full grain contained in cereal passes through the second web plate 19, the first web plate 8 falls into the second collection frame 5
It is interior.
While pouring into cereal, driving first motor 26 is run, and the first flabellum 22 will start turning, and generate air-flow, paddy
Process that object slides from the second web plate 19 and the process to fall to magnetic conveyer belt 11 will generate dust, these dust and residual
Broken wadding will be sucked in exhaust tube 21 by air-flow, and fall in the first dust frame 30.
When especially important, dust filtering web plate 25 will prevent dust and broken wadding from flying out from air outlet 24, to cause environment
Pollution.
When first dust frame 30 needs to take out, wing bolt 35 is rotated counterclockwise, the fixation released to the first sliding sleeve 33 is existing
, therefore the first sliding sleeve 33 can be moved downward along the first slide bar 32, lifter plate 31 will drive the first dust frame 30 from the first peace
Frame up 29 interior taking-ups.
Driven roller 10 will cooperate with driven voller 12 simultaneously, drive magnetic conveyer belt 11 to rotate counterclockwise, so will fall off
Cereal continues to transport to the left, then falls on the first web plate 8 and is screened again.
The iron filings and ferrous metal block contained in cereal will be attached on magnetic conveyer belt 11, and when these connect with scraper plate 17
When touching, scraper plate 17 rejects them from magnetic conveyer belt 11, and is fallen into third collection frame 14 by inclined plate 15.
Cereal passes through the screening again of the first web plate 8, and incongruent cereal and gravel will fall off into the second collection frame 5,
Open first baffle 6, the second collection frame 5 can be taken out, final standard compliant cereal eventually fall into the first collection frame 3 into
Row is collected, therefore has been reached and carried out hierarchical screening to cereal, guarantees that the impurity in cereal can be removed to the greatest extent, and
Screening process does not have excessive dust and generates.
Wherein, which further includes having the second dust frame 36, the second installing frame 37, second gear
Plate 38, mounting base 40, the 4th mounting plate 41, the second motor 42, bearing block 43, dust filtering cover the 44, second shaft 45 and the second flabellum
46；Second installing frame 37 is fixed in a side of the screening frame 4 far from the first installing frame 29, and the second dust frame 36 is placed in the second peace
Frame up bottom in 37, and 37 1 side of the second installing frame offers the second opening 39；Second baffle 38 and the second installing frame 37 are hinged,
And it is located in the second opening 39；4th mounting plate 41 is fixed in 37 top of the second installing frame, the second motor 42 by mounting base 40
It is fixed in the 4th mounting plate 41, dust filtering set 44 is fixed in 37 top of the second installing frame and screening frame 4, bearing block 43 are embedded in dust filtering set
44,45 middle part of the second shaft is pivotally connected with bearing block 43；Second shaft, 45 one end and the output end of the second motor 42 are affixed, another
End and the second flabellum 46 are affixed；The place of 44 handover of screening frame 4 and dust filtering set offers third opening 47.
Driving first motor 26 controls the work of the second motor 42 while operation, the second flabellum 46 will generate air-flow, and work as paddy
Object falls to the process of the first web plate 8 from magnetic conveyer belt 11, and remaining dust and broken wadding will be open 47 by air-flow by third
It sucks in dust filtering set 44, and finally falls in the second dust frame 36, second baffle 38 is opened, it can be by the second dust frame 36
It is taken out out of second installing frame 37.
Wherein, which further includes having the first dustcloth 48, the second sliding sleeve 49, the second slide bar
50, fixed block 51, first links up with the 52, second dustcloth 53, link 54 and the second hook 55；Second slide bar 50 is solid in the horizontal direction
Screening frame 4 is connected to close to a side of the first mounting plate 1, and between the first discharge port 9, the second discharge port 16；First is anti-
48 1 side of dirt cloth and screening frame 4 are affixed, are slidably connected by the second sliding sleeve 49 with the second slide bar 50 at the top of the first dustcloth 48,
Fixed block 51 is fixed in the second one end of the slide bar 50 far from screening frame 4, and the first hook 52 is fixed in fixed block 51, and second is dust-proof
