Description
Technical field
The present invention relates to cereal impurity removing technology field, more particularly to a kind of grain sieving device.
Background technology
In the season that crops are gathered in, peasants need the cereal dried carrying out screening and removing impurities, are entrained in excluding
Cereal free from foreign meter, could to the last be stowed in silo by sand and dust, rice husk, stalk in cereal etc..In tradition
Dedoping step in, it then is that peasants bend over to contain the cereal dried into winnowing pan by the way that ventilating fan frame is high that peasants, which are, directly
Play waist and lift winnowing pan so that then winnowing pan falls down the cereal in winnowing pan, these cereal are blown by ventilating fan higher than ventilating fan
During the wind gone out, the impurity being entrained in cereal can be blown far, so that cereal is separated with impurity.But, it is this traditional
Knot screen make it that the labor intensity of peasant is very big；Moreover, peasant can only screen the winnowing pan of a winnowing pan one to cereal, no
Can continuously it be screened, so screening efficiency is also very low.
The content of the invention
The technical problem to be solved in the present invention is to overcome existing technological deficiency there is provided a kind of labor intensity of peasant is small
And the high grain sieving device of screening efficiency.
The technical solution of the present invention is to provide a kind of grain sieving device with following structure：Including pedestal, material
Bucket, vertical passageway, slanted channel, blower fan, wobble plate, swing rod, support and travelling gear, support are fixedly connected on pedestal, and branch
The collecting bag for holding cereal after removal of impurities is socketed with frame；Hopper is connected with vertical passageway upper port, vertical passageway lower port
Connected with slanted channel upper port, slanted channel lower port is aligned with the collecting bag sack on support, and vertical passageway is fixedly connected
On pedestal；Assembling is offered on the side wall of vertical passageway and led to for blower fan to vertical on the side wall of vertical passageway
What the debris after being offered on the air intake passage of road inner blower, the opposite side wall of vertical passageway for being screened through blower fan was discharged goes out
Wind passage, air intake passage axis is overlapped with air-out passage axis；Described wobble plate is rotatably connected on inside vertical passageway, wobble plate edge
Length direction is provided with multiple strip through holes passed through for the cereal screened without blower fan, and wobble plate, which is provided with, to be used for and vertical passageway
The power transmission shaft of connection is rotated, wobble plate is vertically located above the air intake passage on vertical passageway；Swing rod is rotatably connected on base
On seat, swing rod upper end is provided with arc-shaped rack, and the center of circle of arc-shaped rack is overlapped with the center of rotation on swing rod relative to pedestal, and pendulum
End part of driving shaft on plate, which is provided with, is used for the first gear that arc-shaped rack is engaged, and swing rod lower end is provided with the first open slot；Driving cog
Wheel be rotatably connected on pedestal, travelling gear end face be provided with the first straight pin, the first straight pin to travelling gear axis away from
It is located at from more than zero, first straight pin in the first open slot of swing rod lower end；Vertically it is fixedly connected on described pedestal
Have in the L-shaped rack vertically slidably connected on slide, slide for housing collecting bag, L-shaped rack vertically
Provided with second straight line rack, and second straight line rack is engaged with travelling gear；Described pedestal, which is provided with, to be used to drive driving cog
Take turns the drive device of rotating.
Unscreened cereal can be poured into the present invention in hopper, be then turned on drive device work；Driving dress
Putting can rotate and reverse with nutating gear, and travelling gear can pass through the first open slot and the first cylinder during rotating
The mating band driven fork bottom of pin swings, i.e., swing rod upper end can also swing；Swing rod upper end is being swung
During, it can be rotated by arc-shaped rack with the driving first gear that engages of first gear；That is wobble plate and power transmission shaft
Also first gear synchronous axial system can be followed, so that wobble plate can be rotated relative to vertical passageway, and will be fallen into from hopper vertical logical
The cereal in road is broken up, and facilitates follow-up blower fan to blow down the impurity adulterated in cereal, and impurity is discharged from air-out passage；And exclude
Cereal after impurity then flows through slanted channel and fallen into collecting bag.In addition, the setting of strip through hole can allow paddy in wobble plate
Thing passes through, and improves the effect that wobble plate breaks up cereal.In addition, travelling gear can drive second straight line tooth during reciprocal rotating
Bar is vertically moved back and forth up and down, and then drives L-shaped rack also along shaking or being rocked with this above and below vertical direction to shake
Dynamic or shake collecting bag, then can store compacter, i.e., the cereal density in collecting bag is more by the cereal in collecting bag
More cereal can be stored in height, same collecting bag.Artificial removal of impurities is replaced to greatly reduce farmer by plant equipment
Labor intensity, and can be automated by the device and exclude the impurity that includes in cereal, and can by screening it is good it
Cereal afterwards is directly loaded into collecting bag, and expending extra muscle power without farmer is used to the cereal accumulated on the ground loading receipts
Receive in bag, that is, improve the operating efficiency of screening.Therefore, a kind of labor intensity of peasant of present invention offer is small and screening efficiency is high
Grain sieving device.
As a preferred embodiment, described drive device include guide pad, shell, the first magnet assemblies, the second magnet assemblies,
