Abstract
The utility model relates to a screen, in particular to a double-layer seed selection screen. The problem that a coarse screen and a fine screen are required to be replaced alternatively during seed selection is solved. The double-layer seed selection screen comprises a screen frame. The lower portion of the inner cavity of the screen frame is provided with a fine screen mesh. The middle of the inner cavity of the screen frame is provided with a coarse screen mesh. The lower portion of the front side wall of the screen frame is provided with a seed discharging port which is through internally and externally, and the lower edge of the seed discharging port is flush with the upper surface of the fine screen mesh. The middle of the rear side wall of the screen frame is provided with an impurity discharging port which is through internally and externally, and the lower edge of the impurity discharging port is flush with the upper surface of the coarse screen mesh. A seed discharging blocking plate is installed on the seed discharging port in a sliding mode. An impurity discharging blocking plate is installed on the impurity discharging port in a sliding mode. The left side outer wall and the right side outer wall of the screen frame are respectively provided with one handle. The double-layer seed selection screen is suitable for seed screening, material screening, ore screening and the like.
Description
Technical field
The utility model relates to sieve, specifically a kind of double-deck sifter for seed selection.
Background technology
In daily life, the method for screening seed is: first adopt scalping sieve to remove the large particle diameter impurity (comprising stalk, bulky grain thing etc.) in seed, large particle diameter impurity is stayed in scalping, and seed is drained to outside scalping.Then adopt dusting cover sieve to remove the small particle diameter impurity (comprise not full seed, plant shell etc.) in seed, small particle diameter impurity is drained to outside dusting cover, and make seed stay (seed of staying in dusting cover uses as certified seed) in dusting cover.Therefore, staff, at screening kind of the period of the day from 11 p.m. to 1 a.m, certainly will alternately change scalping and dusting cover, causes thus seed screening inefficiency.Based on this, be necessary to invent a kind of brand-new sieve, need to alternately change the problem of scalping and dusting cover to solve screening kind of the period of the day from 11 p.m. to 1 a.m.
Summary of the invention
The utility model need to alternately be changed the problem of scalping and dusting cover in order to solve screening kind of the period of the day from 11 p.m. to 1 a.m, a kind of double-deck sifter for seed selection is provided.
The utility model is to adopt following technical scheme to realize: double-deck sifter for seed selection, comprises screen frame; The inner chamber bottom of screen frame is provided with fine screen mesh; The inner chamber middle part of screen frame is provided with wide-meshed screen; The front side wall bottom of screen frame offers the inside and outside seed outlet connecting, and the lower limb of seed outlet and the upper surface flush of fine screen mesh; The rear wall middle part of screen frame offers the inside and outside impurity outlet connecting, and the lower limb of impurity outlet and the upper surface flush of wide-meshed screen; On seed outlet, be slidably fitted with seed and discharge baffle plate; On impurity outlet, be slidably fitted with impurity and discharge baffle plate; Left side outer wall and the outer right wall of screen frame are respectively provided with a handles.
Concrete use procedure is as follows: screening kind of the period of the day from 11 p.m. to 1 a.m, the seed that slides respectively discharges baffle plate and impurity is discharged baffle plate, and seed outlet and impurity outlet are closed respectively.Then seed to be screened is poured over to the upper surface of wide-meshed screen.Staff's two hands are held respectively two handles, and the screen frame that rocks from side to side, and screen frame drives wide-meshed screen to rock from side to side together with fine screen mesh thus.Along with the shake of wide-meshed screen, the large particle diameter impurity in seed is stayed the upper surface of wide-meshed screen, and seed drains to the upper surface of fine screen mesh.And along with the shake of fine screen mesh, the small particle diameter impurity in seed drains to the below of fine screen mesh, seed is stayed the upper surface (seed of staying the upper surface of fine screen mesh uses as certified seed) of fine screen mesh.After screening, the seed that slides respectively discharges baffle plate and impurity is discharged baffle plate, and seed outlet and impurity outlet are opened respectively.Then screen frame is turned forward, the seed (being certified seed) of the upper surface of staying fine screen mesh is discharged (now by seed outlet, because impurity outlet is positioned at the rear wall of screen frame, the large particle diameter impurity of the upper surface of staying wide-meshed screen can't be discharged by impurity outlet, thereby avoided large particle diameter impurity and certified seed to mix).Finally screen frame is receded, the large particle diameter impurity of the upper surface of staying wide-meshed screen is discharged by impurity outlet.Based on said process, double-deck sifter for seed selection described in the utility model is by being undertaken integrated by fine screen mesh and wide-meshed screen, make staff without alternately changing scalping and dusting cover, get final product the disposable certified seed that filters out, efficiently solve thus screening kind of the period of the day from 11 p.m. to 1 a.m and need to alternately change the problem of scalping and dusting cover, thereby effectively improved seed screening effeciency.
Further, the outer wall bottom, front side of screen frame is provided with seed and discharges supporting plate, and the upper face of seed discharge supporting plate flushes with the lower limb of seed outlet; The rear side outer wall middle part of screen frame is provided with impurity and discharges supporting plate, and the upper face of impurity discharge supporting plate flushes with the lower limb of impurity outlet.When use, seed is discharged supporting plate and can be made seed discharge more swimmingly.Impurity is discharged supporting plate and can be made large particle diameter impurity discharge more swimmingly.
The utility model is rational in infrastructure, it is ingenious to design, and efficiently solves screening kind of the period of the day from 11 p.m. to 1 a.m and need to alternately change the problem of scalping and dusting cover, is applicable to seed and screens, and is equally applicable to material screening, ore screening etc.
