Description

A kind of harvester and for sorting mechanism on harvester
Technical field:
The present invention relates to a kind of harvester more particularly to a kind of sorting mechanisms of harvester.
Background technique:
The tool that harvester is produced as agricultural modernization is the machinery of integration harvesting crops.Can be used for gathering in paddy, The cereal crops such as wheat, the disposable harvesting for completing harvesting, threshing, separation, screening, pack and one.
Existing small harvester generally comprises pulling feeding part, threshing screen fraction, collection part etc..Pulling feeding Part manually by crop harvesting and can also be deposited in field in advance certainly, then again for pulling up crop by cutting off on soil Hand-held threshing is carried out with thresing machine, the threshing screen fraction can make grain by falling off on stalk and carrying out screening separation, finally The grain separated is subjected to pack operation by collection part.
In existing harvester, it is partially not provided with sorting mechanism, for small harvester, due to sky Between limited, most of sorting mechanism that is not provided with.It only passes through separating mechanism threshing and finishes and just carried out receipts Flexible Container, so that There is also many sundries, such as stone, stalk, weeds in grain or grain.
It is mostly combine harvester for being loaded with the harvester of sorting mechanism, handling capacity is big, and its sorting mechanism is big Existing general sieve is mostly used to carry out vertical tremor screening, therefore, screening effect is still bad, the cereal screened Or impurity is still remained inside grain.And part combination harvester can be screened to reach preferable screening effect using multiple tracks Mode, i.e., first screening finish after to the crops such as grain be collected and pass through auger by together screening after grain again It is secondary to be sent to progress secondary screen choosing in sorting mechanism, it could even be possible to tertiary screen choosing is carried out, to reach combine harvester containing miscellaneous The standard 2.0% of rate.
But for small harvester, there is no enough spaces to carry out the setting of sorting mechanism, or be provided with Sorting mechanism, but it is too short to sieve road, and can not repeatedly be screened, therefore gathers in crop using small harvester, processing The final percentage of impurity of crop is much higher than the percentage of impurity of combine harvester, according to current standard, the percentage of impurity mark of small harvester Standard is 7.0%.
But for most of peasant, especially for the peasant of southwest, due to topography limitation can not or Person is inconvenient to use large-scale combine harvester, can only use small-sized harvester, but the percentage of impurity of small harvester is higher, It generally requires to carry out impurity elimination processing again before selling after the crop gathered in using small harvester.Therefore, it is badly in need of The low small harvester of percentage of impurity can be substantially reduced to one kind, avoids carrying out removal of impurities processing again and leading to increased costs, manually Increase.
Summary of the invention:
