Abstract

The present invention relates to a kind of grain cleaning machines, belong to agricultural machinery technological field.Cereal is transported to from feed inlet in roller by the present invention, cereal follows drum movement under the baffle effect of drums inside, cleaning fan is opened to drums inside air blast simultaneously, cereal moves under baffle effect above drums inside, it falls under the effect of gravity, since impurity is different from grain quality in cereal dropping process, lighter impurity is blown away in dropping process by the wind that wind turbine generates, it is discharged on the right side of from roller, cereal after selection by winnowing is under the effect of gravity constantly to movement on the left of roller, it enters on sieve, sieve screens cereal, remove larger impurity, cereal after screening is fallen into storage bin.Roller is arranged in the present invention skewed, and is arranged to sieve on the left of roller so that cereal enters back into sieve after selection by winnowing and screened, and by the impurity removal that volume in cereal is larger, effectively increases the quality of grain cleaning.

Description

A kind of grain cleaning machine
Technical field
The present invention relates to a kind of grain cleaning machines, belong to agricultural machinery technological field.
Background technology
Main component is rice grain, also many impurity, such as empty grain, short stem in the emersion object of rice combine Stalk, dust etc..The presence of impurity easily makes rice moldy metamorphism, causes the loss of grain, so harvested cereal emersion object It has to pass through and cleans and could be stored.
Cleaning plant is the important component of combine harvester, its function is to utilize to be cleaned each component part of object Between the difference of physical-mechanical properties they are separated, cleaning room is discharged in impurity, it is more clean so as to obtain Seed.Cleaning plant influences the working performance of complete machine, and seed percentage of impurity, the cleaning loss percentage in sorting performance are to weigh connection Close one of the mostly important index of harvester product quality.According to the professional standard JB/T5117 requirements of country:Combining Machine total loss rate≤1.5%, percentage of damage≤2%, impure rate≤0.7%.Some existing domestic harvesters, when gathering in rice, Clean ineffective, loss of cereal crops is excessive, some are 6% or more, and impure rate is 4% or more.Me is can be seen that from data The existing harvester of state, which cleans horizontal and national standard, apparent gap, and indices, which can't reach, once cleans storage It is required that thus will have a direct impact on the product quality of cereal and the operating efficiency of processing of farm products.Therefore, new cereal is studied Clean technique and method has higher theoretical and practical values to enriching, improving existing cleaning plant.
A series of method of cereal cleaned mainly by mechanical works is miscellaneous with other the short stem waited in clear cereal Object removes.There is common grain cleaning mode in agricultural:Screening, selection by winnowing, pneumatic jig combined type.Screening be by sorting screen, according to The difference separation cereal and impurity of cereal and impurity width, thickness and length and shape.Selection by winnowing is a kind of most important cereal Method is cleaned, when cleaning, using difference of the various composition in terms of the aerodynamic properties such as floating velocity in cereal to be cleaned, Complete the separating cleaning of seed and cane, impurity etc..
Sun Shouquan proposes a kind of grain threshing cleaner for combine within 2001, sets about improving from vibrating screen Its internal structure, two pieces of different sieve plates of screen-aperture are arranged on the same vibrating screen and swing together by he, and are sieving Aggregate bin is placed below sub- end, the filled grains being separated can be recycled, be reduced loss late, the breakthrough in structure Also greatly improve the cleaning plant cleans effect.
Feitian thunder irrigates heavy industry and proposes a kind of cleaning and separating apparatus for combine-harvester, the device by drum sieve, double layer planar sieve and Wind turbine forms, and cylinder vibration wire screen is set in the centre position of two horizontal screens.Upper sieve can make the seed tossed out from drum sieve Grain and the sundries such as short cane carry out vibration screening again, lower screen can make the seed fallen from drum sieve and short cane again into Row vibration screening effectively prevents the sundries such as short cane to fall directly into seed screw feeder, preferable to improve seed cleannes.
Invention content
Present invention mainly solves the technical issues of:It is irregular for the distribution of conventional grain cleaning plant interior air-flow field pressure, Cause cereal actual motion track to completely offset from theory movement track, causes larger cleaning loss and percentage of impurity is increased asks Topic, the present invention provides a kind of grain cleaning machines.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention:
A kind of grain cleaning machine, including cleaning fan and roller, the cleaning fan are arranged on the left of roller, cleaning fan It is connected by rotary shaft between roller, the drums inside is provided with baffle, and roller left part is sieve, roller bottom Portion is provided with storage bin, and right side is connected by rotary shaft with holder, is feed inlet above holder.
A kind of application process of grain cleaning machine is:Cereal is transported to from feed inlet in roller, rotary shaft driving rolling Cylinder rotation, cereal follows drum movement under the baffle effect of drums inside, while cleaning fan is opened to drums inside air blast, Cereal moves under baffle effect above drums inside, falls under the effect of gravity, due to impurity in cereal dropping process Different from grain quality, lighter impurity is blown away in dropping process by the wind that wind turbine generates, and is discharged from roller right side, to real Now to the selection by winnowing of cereal, cereal after selection by winnowing constantly to mobile on the left of roller, enters on sieve, in roller under the effect of gravity Continuous rotation lower screen cloth cereal is screened, remove larger impurity, the cereal after screening is fallen into storage bin.
The roller is oblique, and angle of inclination is 30 °.
The cylindric sieve of roller left distal end connection.
The beneficial effects of the invention are as follows:
(1)In the present invention in such a way that selection by winnowing and trommelling are combined, by the way that baffle is arranged in roller so that cereal exists It moves with roller in roller, will fall under the effect of gravity when cereal moves to above drums inside, cereal falls The impurity of lighter weight in cereal can be removed by wind turbine in the process, in this way so that cereal can in roller Selection by winnowing is repeated, effectively increases the quality of impurity removal.
(2)Roller is arranged in the present invention skewed so that when cereal moves in roller, since roller is oblique Cereal during exercise can be to movement on the left of roller, and is arranged to sieve on the left of roller so that cereal enters back into after selection by winnowing Sieve is screened, and the larger impurity of volume in cereal is removed, the quality of grain cleaning is effectively increased.
