Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model screen box structural schematic diagram.
Specific embodiment
As shown in attached drawing 1,2, the utility model includes dust-extraction unit, the screen box being connected with dust-extraction unit 3 and setting
Specific gravity platform 22 below 3 discharge end of screen box is provided with screen box drive link 21, institute between the specific gravity platform 22 and screen box 3
It states and is arranged in rack 19 in the middle part of screen box drive link 21 by shaft, the upper end and the hinge of screen box 3 and lower end and specific gravity platform
22 are hinged.Dust-extraction unit uses spiral dust catcher 29, and the feed end and discharge end of screen box 3 pass through air hose with spiral dust catcher 29
It is connected.It works since specific gravity platform has to outfit motor 25,25 one side of motor provides power for blower, another
Aspect drives the vibration of specific gravity platform 22 by eccentric structure, compares reselection functionality to realize.Specific gravity platform 22 passes through specific gravity platform connecting rod
30 are arranged on the rack, and the both ends of specific gravity platform connecting rod 30 are hinged with specific gravity platform 22 and rack 19 respectively, under the drive of motor 25,
Specific gravity platform 22 realizes vibration.At this point, the change of specific gravity platform 22 will drive screen box drive link 21 and realize reciprocal deflection, to drive screen box
3 carry out vibration screening.Without providing individual power motor for screen box, be greatly saved complete machine manufacturing cost also reduce it is whole
Machine quality.
The honest material exit of specific gravity platform 22 is provided with finished product and connects bucket 23, there is delivery chute more miscellaneous than reclosing at waste outlet
26。
Meanwhile in order to improve the sifting net rate of grain, pneumatic separator is increased in the discharge outlet of screen box mostly at present, to warp
Cross screen box screening after material carry out second wind election, be further reduced adulterated in material it is light miscellaneous.It but is to use mostly at present
The mode of vertical pneumatic jig increases a vertical pneumatic jig in the discharge outlet of screen box and carries out second wind election to material.But it is this only
The pneumatic jig structure of vertical structure is complex and more occupied space when installing, so that complete machine total quality is larger, and is easy
Existing failure.And the pneumatic jig selection by winnowing dynamics of these structures is larger, is more suitable for seed screening field, can will be unsuitable for seed
The particle of production all removes, and improves the quality of seed.But for grain depot storage, it is saturating so high sieve is not needed
Rate, can be wasted using this structure largely can be used for storing the grain used, but if remove the winnowing step, grain
It is light miscellaneous and more in food.
Therefore dust excluding hood is arranged in the discharging side of screen box 3 in the utility model；Screen box 3 includes cabinet, is arranged in cabinet
The first screen frame 4, the sieve 5 being arranged on the first screen frame 4 and the mesh grid 14 being arranged in below sieve 5, in the sieve 5
Ball 13 is provided between mesh grid 14.There is feed hopper 1 in one end of cabinet, is provided between feed hopper and sieve 5
Bulk Grain plate 2, the other end opening of cabinet, as discharging end, the material after screening is discharged from discharging end.The driving connects
Bar 21 and support link 20 are hinged with cabinet.Grain feeding bucket 16, the grain feeding bucket 16 are provided at the feeding inlet of the screen box 3
It is connected by grain feeding bucket dedusting air hose 17 with dust-extraction unit.
The dust excluding hood includes arc-shaped dedusting cover 8, the air duct joint 6 that 8 upper end of dedusting cover is arranged in and sets
The fish scale sieve 10 below dedusting cover 8 is set, is fixedly installed with the second screen frame 11 in the top surface of cabinet, fish scale sieve 10 is installed
On the second screen frame 11, and the fish scale sieve 10 is located at the top of sieve 5.Between dedusting cover 8 and fish scale sieve 10
Gap forms dedusting cavity, and dedusting cavity one end other end that is connected with the discharging end of screen box 3 is connected with air duct joint 8.Institute
It states air duct joint 6 dirt air hose 18 is screened out by Horizontal wind and be connected with pneumatic separation device.
Inclined wind deflector 7 is installed between the fish scale sieve 10 and air duct joint 6.Wind deflector 7 can change wind
Pipeline joint 6 is for the attraction direction of dedusting negative pressure and cavity wind, if the not wind deflector 7, the wind direction of air duct joint 6 is along wind
Pipeline joint 6 moves towards to attract, and forms nearly 90 degree of angle with dedusting cavity, attracts effect poor.Wind deflector 7 changes negative pressure
Negative pressure wind of the air duct joint 6 for dedusting cavity is changed to connect subparallel direction by the trend of wind, and such vacuum suction is more preferable,
It can effectively improve the saturating rate of sieve.
Cleaning door 9 is provided on the top surface of the dedusting cover 8.
The small miscellaneous small miscellaneous outlet 15 sifted out for accepting screen box 3 is provided in the lower section of the screen box 3, in the sieve
The discharge end of case 3 is provided with product outlet 12, and the product outlet 12 is connected with dedusting cavity.
The dust excluding hood of the utility model can manufacture integrally fixed form with screen box, and when machine assembly is whole as one
Module is assembled, and without being additionally provided installation space for selection by winnowing, while total quality is lighter.
The utility model passes through air hose with discharge outlet in the feeding inlet of screen box and connects dust-extraction unit, to progress Secondary Air
Choosing can greatly improve the sifting net rate of finished product.
Above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；Although referring to aforementioned reality
Example is applied the utility model is described in detail, those skilled in the art should understand that: it still can be to preceding
Technical solution documented by embodiment is stated to modify or equivalent replacement of some of the technical features；And these are repaired
Change or replaces, the spirit and scope for the utility model embodiment technical solution that it does not separate the essence of the corresponding technical solution.
