Description
Technical field
The present invention relates to grain cleaning technical field, particularly relate to a kind of grain header cleaning and sorting system.
Background technology
The dressing mechanisms such as reciprocating sieve are had when large-scale harvester is cleaned, but small harvester crushing straw when thrashing cylinder is simply cleaned is transported to way to move grains and connects grain mouth, percentage of impurity is high, though through fan induced draught, utilize stalk different from the proportion of cereal and reach and tentatively clean, but fall by can become to concentrate when carrying way to move grains out due to cereal, part stalk can be mixed in cereal, fall with cereal, cause the percentage of impurity cleaning rear cereal too high, fail stalk in cereal to be separated with the grain degree of depth.
Summary of the invention
In order to solve the technical problem existed in background technology, the present invention proposes a kind of grain header cleaning and sorting system, achieving and grain in cereal and stalk are carried out the degree of depth being separated, its structure is simple, cleans effective.
A kind of grain header cleaning and sorting system that the present invention proposes, comprise and clean air duct, air exhauster and grain sack, clean air duct and there is cylindrical outer wall, clean air duct both ends open, wherein, one end is air intake opening, the other end is air-out opening, air exhauster by air-out opening with clean air duct and be communicated with, grain sack is positioned at below air intake opening, the area of air-out opening is less than the area of air intake opening, clean in the middle part of air duct is the portion of cleaning, the portion of cleaning is straight-tube shape and its side is provided with cereal entrance, clean between portion and air intake opening is scroll portion, scroll portion is taper tubular, clean in air duct inner chamber and be provided with vortex generating mechanism, vortex generating mechanism comprises some guide vanes, one end of guide vane is fastened on air intake opening part, and the other end is positioned at the portion of cleaning and scroll portion junction, each guide vane is close to cylindrical outer wall and is arranged, guide vane is bending along its length and each guide vane bending direction is consistent, guide vane away from the level height of air intake open at one end lower than cereal entrance.
Preferably, each guide vane is evenly distributed.
Preferably, clean in the middle part of air duct and be provided with airtight watch window.
Preferably, watch window and cereal entrance are oppositely arranged.
In the present invention, grain conveying device by cereal entrance with clean air duct and be communicated with, cereal enters through cereal entrance in the inner chamber cleaning air duct and cleans portion, air-flow is passed into cleaning in air duct inner chamber by air intake opening, air-flow forms eddy airstream through vortex generating mechanism in scroll portion, clean the cereal in portion disperseed in the effect of eddy airstream and form of short duration suspension, the stalk that density is less flies out from air-out opening with eddy airstream, the grain that density is larger drops from air intake opening under gravity, thus achieve being separated of stalk and grain, complete cleaning of cereal, wherein, vortex generating mechanism is designed to be made up of some guide vanes, by one end of guide vane is fastened on air intake opening part, and the other end is positioned at the portion of cleaning and scroll portion junction, increase the stroke of air-flow in vortex production mechanism, the intensity of the eddy airstream of formation can be improved, guide vane is designed to bend along its length and each guide vane bending direction is consistent, also the intensity of the eddy airstream of formation can be improved further, the portion of cleaning is designed to straight-tube shape be also conducive to further improving the stability of eddy airstream in the portion of cleaning, thus effect is cleaned in raising.
Accompanying drawing explanation
