Enter to clean in the inner chamber of air duct and clean portion, air duct inner chamber is passed through air-flow, gas by air intake opening to cleaning
Flow through vortex generating mechanism and form eddy airstream, clean the corn in portion and disperseed also in the effect of eddy airstream
Forming of short duration suspension, the straw that density is less flies out from air-out opening with eddy airstream, the paddy that density is bigger
Grain drops from air intake opening under gravity, it is achieved thereby that straw separates with grain, completes corn
Cleaning, wherein, vortex generating mechanism is designed as being made up of some guide vanes, its simple in construction, vortex gas
Stream is easily formed and adjusts, and the portion of cleaning is designed as straight-tube shape the most beneficially raising eddy airstream clearly
Select the stability in portion, thus improve and clean effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of cleaning and sorting machine for harvester that the present invention proposes.
Detailed description of the invention
As it is shown in figure 1, the structural representation of a kind of cleaning and sorting machine for harvester that Fig. 1 is the present invention to be proposed.
With reference to Fig. 1, a kind of cleaning and sorting machine for harvester that the present invention proposes, including cleaning air duct, described in clean wind
Cylinder there is cylindrical outer wall, described in clean air duct both ends open, wherein, one end is air intake opening, and the other end is
Air-out opening, and connected with outside air exhauster by described air-out opening, the area of described air-out opening is less than
The area of described air intake opening, described in clean in the middle part of air duct as the portion of cleaning, described in the portion of cleaning be straight-tube shape and its
Side is provided with corn entrance 1, and described air intake opening part is provided with vortex generating mechanism, and described vortex generates machine
Structure includes that some guide vanes 3, one end of described guide vane 3 are fastened on described air intake opening part, and another
End is cleaned in air duct inner chamber described in being positioned at, the length direction of described guide vane 3 and the described axle cleaning air duct
< 90 °, the incline direction of each described guide vane 3 is identical, described guide vane 3 for and α angle at an angle to direction
Level height away from described air intake open at one end is less than described corn entrance 1.
During specific design, described in clean and in the middle part of air duct, be provided with airtight watch window 2, consequently facilitating
The situation of cleaning is observed, to adjust air-flow size according to practical situation.
In the present embodiment, 30 °≤α angle≤60 °, α angle uses above-mentioned angle, and the eddy airstream of formation is stable,
