Abstract
The utility model relates to a kind of grain cleaner, comprises feed system, front dust pelletizing system, screening system, rear dust pelletizing system; The adjustment of described feeding capacity installs feeding agitator by spout place and feeding drum controls; Described air quantity is regulated by frequency control; Sieve is in " tilting in the other direction " configuration; Former and later two expansion chambers are established below described grain cleaner fan induced draught mouth.The utility model has compact conformation, selection by winnowing is effective, functional.
Description
Technical field
The utility model belongs to grain cleaner field, particularly a kind of grain cleaner.
Background technology
Because the different harvesting method of harvest machinery is different, just different in the quality of different region, place seeds and grain, have many alloys just to occur in seed after harvesting and grain, such as weed seed, handstone, crushing straw, degeneration, the seed of immature, disease damage, mechanical damage or grain.Seed and grain cleaner in this case in order to obtain high-quality have just occurred.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of grain cleaner.
Technical solution of the present utility model: a kind of grain cleaner, comprises feed system, front dust pelletizing system, screening system, rear dust pelletizing system; The adjustment of described feeding capacity installs feeding agitator by spout place and feeding drum controls; Described air quantity is regulated by frequency control blower fan; Sieve is in " tilting in the other direction " configuration; Former and later two expansion chambers are established below this grain cleaner fan induced draught mouth described.
Further, feeding agitator and feeding drum are installed by described spout place, and feeding agitator is connected by Chain conveyer with feeding drum, and driven by a variable frequency adjustment motor, the rate of feeding of adjustable like this cleaner, makes cereal freely flow continuously, ensures continuous, even feeding.
Further, sieve is in " tilting in the other direction " configuration, and screen box all has self-balancing effect in front and back and above-below direction, thus the vibrations of machine are obviously reduced.
Further, below described grain cleaner fan induced draught mouth, establish former and later two expansion chambers, realize feeding end and discharge end twice removal of impurities, improve purification capacity, bottom expansion chamber, be provided with impurities removal screw feeder.
beneficial effect:
Compared with prior art, grain cleaner of the present utility model has the features such as compact conformation, selection by winnowing be effective, functional to the improvement of grain cleaner with produce significant.Alleviate peasant's labour intensity, improve the quality of production and labor productivity, realize the dressing machine tool in vast rural area.
accompanying drawing illustrates:
Fig. 1 is structure chart of the present utility model;
In Fig. 1, the assorted remaining spiral propeller of 1-ladder shuttle board, 2-fan, 3-sieve, 4-cereal spiral propeller, 5-.
Detailed description of the invention
As shown in Figure 1, grain cleaner of the present utility model, comprises feed system, front dust pelletizing system, screening system, rear dust pelletizing system; The adjustment of described feeding capacity installs feeding agitator by spout place and feeding drum controls; Described air quantity is regulated by frequency control blower fan; Sieve is in " tilting in the other direction " configuration; Former and later two expansion chambers are established below this grain cleaner fan induced draught mouth described.
Wherein, described at spout place installation feeding agitator and feeding drum, feeding agitator is connected by Chain conveyer with feeding drum, and driven by a variable frequency adjustment motor, the rate of feeding of adjustable like this cleaner, makes cereal freely flow continuously, ensures continuous, even feeding.Sieve is in " tilting in the other direction " configuration, and screen box all has self-balancing effect in front and back and above-below direction, thus the vibrations of machine are obviously reduced.Establish former and later two expansion chambers below this grain cleaner fan induced draught mouth described, realize feeding end and discharge end twice removal of impurities, improve purification capacity, bottom expansion chamber, be provided with impurities removal screw feeder.
During work, crop seeds to be cleaned enters the import suction channel of impurity removed system by feeding hopper, wherein spout has plate valve to control, wind-force is adjusted in advance according to category, this time is the dust in material and flat seed and slightly gently mix by dedusting and light discharger of mixing, heavier light mixing falls into bottom expansion chamber, discharged by auger conveyor bottom it, then material is fallen on screen box ground floor compass screen surface, along with the vibration of sieve, some irregular culm and clods, because impurity is comparatively large, will go out have compass screen surface to flow out by assorted mouth.Remaining material is fallen on second layer compass screen surface through sieve aperture, is constantly vibrated by sieve, discharges under residual assorted in seed flows to sieve by second layer compass screen surface from impurity outlet; And cleaner seed second layer compass screen surface hole slides into compass screen surface end, the fine impurities such as lightweight silt and weeds bits, through outlet suction channel by sucking-off again, last material is discharged from discharging opening.
Embodiment recited above is only be described the preferred embodiment of the present invention, not limits the spirit and scope of the present invention.Under the prerequisite not departing from design concept of the present invention; the various modification that this area ordinary person makes technical scheme of the present invention and improvement; all should drop into protection scope of the present invention, the technology contents of request protection of the present invention, all records in detail in the claims.
