Description
Technical field
The utility model relates to grain processing equipment field, particularly, relates to a kind of cereal selection by winnowing screening machine.
Background technology
Grain screening is a kind of for cereal is screened with impurity the device be separated.Due in the cereal of results containing comprising stalk, earth and some other granule foreign, in order to ensure after the putting in storage of cereal in quality, need to screen cereal before cereal puts in storage, remove impurity.
The principle of grain screening: be separated according to the different of size between cereal from impurity, conventional vibrations mesh screen structure processes, and because the mesh of mesh screen is certain, the particle filtering being less than mesh can be fallen, the particle that size is greater than mesh is then retained on mesh screen.
Owing to containing different types of impurity in cereal, the size of various impurity is also the same, and existing screening plant thoroughly by cereal and magazins' layout, and can not process for some dusts be attached on cereal nowhere.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of cereal selection by winnowing screening machine, to overcome the problem that cereal thoroughly can not be separated with impurity, can not be separated cereal and dust by existing screening plant.
The technical scheme in the invention for solving the above technical problem is: cereal selection by winnowing screening machine, comprise frame, the top of frame is provided with charging seat, charging seat is provided with feed hopper, frame sets gradually once screen tray below feed hopper, secondary screen tray, secondary vibration mesh screen is provided with in secondary screen tray, a vibrating screen is provided with in a screen tray, the sidewall of a screen tray is provided with trash discharge bucket, secondary screen tray is set to incline structure, the bottom of incline structure is provided with discharging opening, the below of discharging opening is provided with discharging channel, the mesh of a described vibrating screen is greater than the size of cereal, the mesh of described secondary vibration mesh screen is less than the size of cereal, the below of described discharging opening is provided with inlet scoop, and inlet scoop is connected with pipeline, and the exit of pipeline is provided with air blast.
Existing grain sieving device is all generally adopt one deck vibrating screen to screen cereal, normally the aperture of mesh screen is slightly larger than the size of cereal, the impurity such as larger-size stalk are made to be intercepted at mesh screen upper end, and the storing bin that the less cereal of size is arranged to lower end by screen filtration, the less granule foreign of some sizes enters in storing bin together along with cereal, cause can not being thoroughly separated between cereal with impurity, and some dusts be attached on cereal are processed nowhere.
A vibrating screen described in the utility model, secondary vibration mesh screen are a kind of existing Structure of Vibrating Screen, realize the vibration of mesh screen under external force (motor or other external force) effect; Described incline structure specifically refers to that secondary screen tray and horizontal plane have certain angle and make secondary mesh screen be inclined plane, then the bottom that the cereal be convenient to after screening is slipped to incline structure enters into discharging opening, and the bottom of the bottom of described incline structure specifically refers to the position that inclined plane is crossing with horizontal plane; A described vibrating screen preferably tilts towards trash discharge bucket, and the impurity landing being convenient to the larger-size stalk tackled on a vibrating screen is discharged at trash discharge bucket place.
The course of work of the present utility model: put into a screen tray by feed hopper by needing the cereal of screening, mesh due to a vibrating screen is greater than the size of cereal, cereal and the less impurity of size is made to enter into secondary screen tray by a vibrating screen, and the impurity such as larger-size stalk are intercepted at a vibrating screen upper end, vibration along with a vibrating screen is slipped to trash discharge bucket place and discharges, mesh due to secondary vibration mesh screen is less than the size of cereal, the impurity making size less is by secondary vibration mesh screen, cereal is then intercepted at secondary vibration mesh screen, because secondary vibration mesh screen is incline structure, cereal is slipped to discharge outlet in secondary vibration mesh screen vibration processes, in discharge outlet owing to being provided with inlet scoop, under the effect of air blast, dust on cereal is drawn in pipeline by inlet scoop and discharges, then the discharging channel be arranged on below discharging opening discharges storage not have the cereal of dust to enter into.
The utility model is greater than a vibrating screen of the size of cereal by arranging mesh, mesh is less than the secondary vibration mesh screen of the size of cereal, cereal is successively through a vibrating screen, the gradation sizing of secondary vibration mesh screen, larger-size impurity is discharged by trash discharge bucket by a vibrating screen interception, the impurity that size is less passes through secondary vibration mesh screen, cereal thoroughly and magazins' layout, cereal enters into discharging channel by the secondary vibration mesh screen tilted and discharges storage, thoroughly and magazins' layout, so, the utility model overcomes the problem that cereal and impurity can not thoroughly be separated by existing screening plant.
Further, frame is provided with holder, holder is provided with angle adjustment plate, angle adjustment plate is provided with adjustment hole, described secondary screen tray is arranged on holder by angle adjustment plate.
Angle adjustment plate described in the utility model specifically refers to a kind of for regulating the structure of secondary screen tray gradient, then bolt coordinates with the screwed hole on secondary screen tray realize secondary screen tray and angle adjustment plate to fix through adjustment hole, coordinates by the adjustment hole of adjustment secondary screen tray and differing heights the adjustment realizing secondary screen tray gradient.
Further, frame is provided with driving mechanism, driving mechanism is connected with bearing by connecting rod, and bearing is connected with holder, holder is disposed with secondary screen tray, a screen tray.
Further, stating driving mechanism is motor or hydraulic jack.
Further, the lower end of frame is provided with pedestal, and pedestal is provided with protective cover.
Further, vibrating screen, secondary vibration mesh screen are provided with fixed bar.
Fixed bar described in the utility model specifically refers to a kind of structure for improving vibrating screen, secondary vibration mesh screen structural stability, because vibrating screen, secondary vibration mesh screen will bear the gravitational thrusts from cereal and impurity, the poor meeting of Stability Analysis of Structures of mesh screen causes the distortion of mesh screen, fixing setting effectively can improve the structural stability of vibrating screen, secondary vibration mesh screen, slows down the trend of vibrating screen, secondary vibration mesh screen generation deformation.
Further, the exit of pipeline is provided with collection frame.
Further, inlet scoop place is provided with the screen pack that filter opening is less than cereal size.
Air blast is avoided to discharge in cereal intake line when effect.
To sum up, the beneficial effects of the utility model are:
1, the utility model is greater than a vibrating screen of the size of cereal by arranging mesh, mesh is less than the secondary vibration mesh screen of the size of cereal, cereal is successively through the gradation sizing of vibrating screen, secondary vibration mesh screen, larger-size impurity is discharged by trash discharge bucket by a vibrating screen interception, the impurity that size is less passes through secondary vibration mesh screen, cereal thoroughly and magazins' layout, cereal enters into discharging channel by the secondary vibration mesh screen tilted and discharges storage, thorough and magazins' layout.
2, the utility model is by arranging inlet scoop in discharge outlet, wind inlet connecting pipe, by the effect of air blast by the dust intake line on discharge outlet cereal, avoids dust to be attached on cereal and enters granary.
