Description
Technical field
The present invention relates to cereal impurity removing technology field, more particularly to a kind of device for grain screening.
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 device for grain screening of screening efficiency.
The technical solution of the present invention is to provide a kind of device for grain screening with following structure：Including
Pedestal, hopper, vertical passageway, slanted channel, blower fan, wobble plate, swing rod, support and travelling gear, support are fixedly connected on pedestal
On, and the collecting bag for holding cereal after removal of impurities is socketed with support；Hopper is connected with vertical passageway upper port, vertical passageway
Lower port is connected with slanted channel upper port, and slanted channel lower port is aligned with the collecting bag sack on support, and vertical passageway is solid
Surely it is connected on pedestal；Assembling on the side wall of vertical passageway, offered on the side wall of vertical passageway for blower fan to
Debris row after being offered on the air intake passage of vertical passageway inner blower, the opposite side wall of vertical passageway for being screened through blower fan
The air-out passage gone out, air intake passage axis is overlapped with air-out passage axis；Described wobble plate is rotatably connected on inside vertical passageway,
Wobble plate 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 to turn with vertical passageway
The power transmission shaft of dynamic connection, wobble plate is vertically located above the air intake passage on vertical passageway, and opening is provided with the middle part of power transmission shaft
Second open slot directed downwardly；Swing rod is rotatably connected on pedestal, and swing rod upper end is provided with the second straight pin, and the second straight pin is located at pendulum
In the second open slot on plate, vertical passageway side wall is provided with the arc-shaped through-hole slided for the second straight pin, the circle of arc-shaped through-hole
The heart is overlapped with the center of rotation on swing rod relative to pedestal, and swing rod lower end is provided with the first open slot；Travelling gear is rotatably connected on
On pedestal, travelling gear end face is provided with the first straight pin, and the distance of the first straight pin to travelling gear axis is more than zero, first
Straight pin is located in the first open slot of swing rod lower end；Vertically it is fixedly connected with described pedestal on slide, slide
Vertically slidably connect and second straight line tooth is vertically provided with the L-shaped rack for housing collecting bag, L-shaped rack
Bar, and second straight line rack engages with travelling gear；Described pedestal is provided with the driving for being used for driving travelling gear rotating
Device.
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, drive axis can be driven by the cooperation of the second straight pin and the second open slot；That is wobble plate also can
Follow power transmission shaft to be rotated relative to vertical passageway, and the cereal that vertical passageway is fallen into from hopper is broken up, facilitate follow-up
Blower fan blows down the impurity adulterated in cereal, and impurity is discharged from air-out passage；And the cereal after despumation then flow through it is oblique
Passage is fallen into collecting bag.In addition, the setting of strip through hole can allow cereal to pass through, the effect that wobble plate breaks up cereal is improved
Really.In addition, travelling gear can drive second straight line rack vertically to move back and forth up and down during reciprocal rotating, enter
And drive L-shaped rack also along shaking or being rocked with this above and below vertical direction to rock or shake collecting bag, it will can then receive
The cereal in bag of receiving stores compacter, i.e., the cereal density in collecting bag is higher, can be stored more in same collecting bag
Many cereal.Replace artificial removal of impurities to greatly reduce the labor intensity of husbandmen by plant equipment, and pass through the device
The impurity for excluding and being included in cereal can be automated, and the cereal after screening well can be directly loaded into collecting bag,
Expending extra muscle power without farmer is used to the cereal accumulated on the ground being fitted into collecting bag, that is, improves the work effect of screening
Rate.Therefore, the present invention provides a kind of device for grain screening that the labor intensity of peasant is small and screening efficiency is high.
