Description
Technical field
The invention belongs to agricultural machinery, relates generally to a kind of grain cleaning sieve.
Background technique
Sorting screen on current corn sorting device is the single compass screen surface structure of rigid monoblock type, and whole compass screen surface cleans work
Vibration frequency when industry is consistent with amplitude.It is found in production operation using practice, that cleans out is miscellaneous remaining in monoblock type compass screen surface
Packing phenomenon easily occurs for rear portion, cannot be discharged in time, affect the dispersion on compass screen surface of the corn kernel cleaned and mixture, point
Layer reduces the screening quality effect of equipment and cleans operating efficiency, and miscellaneous remaining middle entrainment corn kernel is more, and seed is caused to damage
It loses.
Summary of the invention
The purpose of the invention is aiming at the above-mentioned problems of the prior art, a kind of jade of new construction of researching and designing
Rice seed cleaning combines screening mechanism with impurities removal, reaches the dispersion improved corn kernel and mixture on major and minor sorting screen surface, divides
The purpose that miscellaneous remaining, guarantee cleans operation quality, reduces seed entrainment loss is quickly discharged in layer effect, realization.
The purpose of the invention is achieved in that corn kernel cleans that screening mechanism is combined with impurities removal includes mechanism rack,
The installation driving shaft and driven shaft being parallel to each other on the downside of the mechanism rack left end on position, on driving shaft and driven shaft respectively
It is fixedly mounted with driving gear, eccentric wheel A and driven gear, eccentric wheel B；It respectively can on the forward and backward outside left in mechanism rack left end
The hinge of swing installs two-way rocking bar；Support is hinged and installs main sorting screen respectively in the top and bottom portion of the two-way rocking bar
Being hinged with hanging, installation is secondary to clean main sieve；Tune can be moved left and right from left to right on mechanism rack front and rear sides upper end
The equipped Holder for hanging household utensiles A and Holder for hanging household utensiles B of section are hung on the Holder for hanging household utensiles A by the adjustable sunpender assembly hinge of screw-type bi-directional expansion
Secondary sorting screen is hung, the pair sorting screen can be controlled to be supported on main sorting screen integrally to the mobile insertion adjusted of pull, main clear
Choosing sieve and secondary sorting screen are in that left low and right high shape is arranged obliquely, and the both ends of sorting screen actuating arm are hinged at eccentric wheel B and master respectively
On sorting screen, sieved on the Holder for hanging household utensiles B by the miscellaneous remaining discharge of sunpender hinge hanging installation, miscellaneous remaining discharge sieve is located at pair sorting screen
Lower right-hand side position at, and be arranged obliquely in left low and right high shape, the both ends for the adjustable actuating arm that stretches are hinged at eccentric wheel A respectively
On miscellaneous remaining discharge sieve；The opposite installation branch of adjusting can be moved left and right from left to right on mechanism rack front and rear sides position
Plate is hinged by supporting crank on the supporting plate and supports miscellaneous remaining discharge sieve；It can on the forward and backward side lower part of mechanism rack right end
The installation support base for moving left and right adjusting is hinged by the adjustable strut assembly of screw-type bi-directional expansion on support base and supports installation
It is secondary to clean secondary sieve, it is described it is secondary clean secondary sieve and be located at miscellaneous remaining discharge sieve lower section, it is secondary clean secondary sieve can control it is mobile to pull
The insertion of adjusting be supported on it is secondary clean it is integral on main sieve, it is secondary to clean main sieve and secondary clean secondary sieve and incline in left low and right high shape
Tiltedly configuration；The vibration frequency of the main sorting screen and secondary sorting screen is greater than the vibration frequency of miscellaneous remaining discharge sieve, the main sorting screen
For amplitude with secondary sorting screen less than the amplitude of miscellaneous remaining discharge sieve, the main sorting screen, the tilt angle of secondary sorting screen are remaining greater than miscellaneous
It is discharged the tilt angle of sieve, it is described secondary to clean main sieve, the secondary tilt angle for cleaning secondary sieve and main sorting screen, secondary sorting screen
Tilt angle is equal.
Traditional rigid monoblock type sorting screen is decomposed into adjustable compass screen surface according to material screening theory by the invention
Length and mutually matched main sorting screen and secondary sorting screen and miscellaneous remaining discharge sieve structure, and using the vibration of major and minor sorting screen frequency
Rate is greater than miscellaneous remaining discharge sieve, its amplitude is less than the technical parameter selection of miscellaneous remaining discharge sieve, is accelerating the miscellaneous remaining velocity of discharge and effect
It rate and avoids miscellaneous remaining while being accumulated on compass screen surface, and improves corn kernel and mixture on major and minor sorting screen compass screen surface
The rate of recovery is cleaned in dispersion, layered effect, guarantee, reduces grain loss, have structure novel, uniqueness, rationally, operation quality it is good,
High-efficient, adjusting simple and convenient, adaptable, service-strong feature.
