Description
Technical field
It is particularly a kind of for being carried out before cereal deep processing enterprise and grain storage the present invention relates to a kind of grain machinery
The combined cleaning sieve of multipass sort.
Background technology
The cereal such as paddy 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 carry 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
For 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
Cleaning equipment is planted, its distinct device has its different performance and feature, also respectively have its not enough.For example：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 just very poor；Screening installation, Main Function is 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 current these simple functions, 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 still suffer from setting
Standby huge, efficiency is low, noise and the defect such as dust is big.Generally, when grain screening installation works, due to needing cereal
Flying upward carries out dust suction and screening, so the dust inside machine is very big.When cereal is 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 occurs slack existing when by sieve aperture
As so as to reduce screening efficiency.
A series of multifunctional combination cleaning sieves have been invented by development for many years by our company, and selection by winnowing is entered with screening installation
Row multifunctional combination.Operating efficiency is improve, 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 base plate of monoblock type screen box, by external air intake device so that screen box one
Side swing type gravity screening, while being siphoned away the dust and husk of lightweight by inlet scoop.Though the screen box upside of the patent is expected
Setting brush mechanism, the brush mechanism is 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 base plate, it is impossible to when passing through cereal
Fully fly upward, almost do not have the effect of anticipation, compass screen surface is often blocked, air draught dust removing effects are poor.
In order that cereal is in primary selection by winnowing, can sufficiently be flown upward, so that pick-up performance reaches most preferably, 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）, in air draught dress
In the presence of putting, without any power, when cereal passes through in clear grain device, cross section is the bending of J-shaped to clear grain device in casing
Under plate effect, 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, completion once primary sorting.Product
Simple structure, 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 screening again.
The product of current grain cleaning sieve is a lot, but still suffers from many problems, it is necessary to further research and development and innovation, improve
Sorting quality and efficiency, reduce running noises, screen box even running.
The content of the invention
Technical barrier to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of many fractions of grain
