Description
Technical field
A kind of grain machinery is the utility model is related to, before particularly one kind is used for cereal deep processing enterprise and grain storage
Carry out the combined cleaning sieve of multipass sort.
Background technology
The cereal such as rice are contaminated with substantial amounts of such as weeds, stalk, fag end, brick and tile, stone, glass fragment after harvesting
Debris, grain is before storage, it is necessary to carries out sorting cleaning to debris therein.The debris mixed in cereal, because species is more,
It is divided into again by its quality light miscellaneous（Such as rice husk, dust, crushing straw）It is miscellaneous with weight（Such as sand, blinding）, divide again by its volume
To be big miscellaneous and small miscellaneous.Cleaning equipment in current existing grain machinery, is all simple function, and such as selection by winnowing, gravity screening is several
Kind cleaning equipment, its distinct device, there is its different performance and feature, also respectively there is its deficiency.Such as：Pneumatic separator, it is main to make
Be separate it is light miscellaneous in cereal, it is good but miscellaneous, big to the weight of such as stone, big stalk etc. to light miscellaneous and dust cleaning effect
Miscellaneous cleaning effect is with regard to very poor；Screening installation, main function are the big or small impurity of segregation ratio cereal grain, and its counterweight is miscellaneous and big miscellaneous
Cleaning effect is good, but is very difficult to remove to gently miscellaneous.The grain cleaning equipment of these simple functions at present, counterweight it is miscellaneous and it is light it is miscellaneous can not
Once property completes sorting cleaning on same machine, and this is put in storage for large-scale grain processing enterprise and large-scale grain storage
Enterprise, it is clear that very big inconvenience can be brought.The multifunctional combination for also having some combined types at present is sieved, but these equipment are still suffered from and set
The defects of standby huge, efficiency is low, noise and dust are big.Generally, when grain screening installation works, due to needing cereal
Carry out dust suction and screening are flown upward, so the dust inside machine is very big.Cereal when being screened on the compass screen surface of screen box,
Also often sieve aperture is blocked because some impurity are trapped on compass screen surface so that cereal is slack existing by occurring during sieve aperture
As so as to reduce screening efficiency.
Our company has invented a series of multifunctional combination cleaning sieves, selection by winnowing and screening installation has been entered by development for many years
Row multifunctional combination.Operating efficiency is improved, makes compact integral structure, dust-proof, but still suffered from structure design, development
There is deficiency, it is necessary to constantly perfect.
The applicant applied " a kind of gravity flow primary separating sieve " on July 11st, 2015（The patent No.
2015104032970）, several inlet scoops are opened up on the bottom plate of monoblock type screen box, pass through external air intake device so that screen box one
Side swing type gravity screening, while being siphoned away the dust of lightweight and husk by inlet scoop.Though expect on the upside of the screen box of the patent
Setting brush mechanism, the brush mechanism are eccentric ratio type of drive, and brush can only be fixed on the top of compass screen surface, to compass screen surface
The cleaning that is not stopped of part, but brush brush less than place, can still block the other positions of compass screen surface.In addition, this is special
Sharp technology still has many immature, inlet scoops of the so-called Z-type step on screen box bottom plate, it is impossible to when passing through cereal
Fully fly upward, almost do not have the effect of anticipation, compass screen surface often blocks, and air draught dust removing effects are poor.
In order that cereal in primary selection by winnowing, can sufficiently be flown upward, so that pick-up performance reaches optimal, this hair
A person of good sense applied " a kind of clear grain device of gravity flow selection by winnowing " on January 23rd, 2016（The patent No. 2016200636613）, filled in air draught
In the presence of putting, clear grain device without any power, cereal in clear grain device by when, cross section is the bending of J-shaped in casing
Under plate effect, it can automatically seethe and fly upward, greatly increase the pick-up performance to cereal.The patented product can independently make
With as long as suction port is docked on the existing air-drafting and dust-removing device of grain depot, you can use, complete once primary sorting.Product
Simple in construction, small volume is easy to use.But the patented product can only be a primary cleaning plant, for massive debris
Also need to carry out gravity again to screen.
The product of grain cleaning sieve is many at present, but still suffers from many problems, it is necessary to further research and develop and innovate, and improves
Sorting quality and efficiency, reduce running noises, screen box even running.
The content of the invention
Technical barrier to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of grain is more
