Field technology personnel are badly in need of the technical problem solved.
Utility model content
For deficiencies of the prior art, the purpose of this utility model is that solving the existing harvester course of work
Middle grain and debris separating rate are slow, low separation efficiency, and the problem of inferior separating effect, there is provided a kind of harvester selection by winnowing system
System, can carry out grain quickly, efficiently and exactly and separate with debris, so as to greatly improve the work efficiency of harvester.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is such：A kind of harvester selection by winnowing
System, including threshing bin, thrashing cylinder, material conveyor, separation bin and wind turbine；It is characterized in that：The material conveying twists
Dragon includes screw-conveyer-shaft, the first helical blade and the second helical blade；Material casting plate is equipped with screw-conveyer-shaft, and the material casting plate is located at
Between the both ends of screw-conveyer-shaft；First helical blade and the second helical blade are around being located on auger, and respectively from screw-conveyer-shaft
Both ends extend to material casting plate, and are connected with material casting plate；Wherein, the precession direction phase of the first helical blade and the second helical blade
Instead, make in screw-conveyer-shaft rotation process, material can be delivered at material casting plate by the first helical blade and the second helical blade at the same time；
In the bottom of threshing bin side, the position of the corresponding material casting plate is equipped with material discharge port；
The separation bin is located at the same side of threshing bin with material discharge port, and is connected with the material discharge port；The wind
Machine is located at the opposite side of threshing bin, its air outlet is located at the underface of material discharge port.
Further, the position of the top corresponding material outlet of the separation bin has debris discharge port, its bottom is close
The position of one end has grain discharge port, and a grain conveying auger is equipped with separation bin, can by the grain conveying auger
Grain is delivered to grain discharge port.
Further, a wind direction adjusting plate, the wind direction adjusting plate and separation bin side wall are equipped with the lower section of fan outlet
Rotation connection.
Compared with prior art, the utility model has the following advantages that：
1st, it is simple in structure, the material at thrashing cylinder both ends can be carried out to material casting plate at the same time by material conveyor defeated
Send, thus greatly reduce material time of delivery, improve the transfer efficiency of material, improve the work efficiency of harvester.
2nd, material conveyor is equipped with material casting plate, and when material is delivered at material casting plate, material casting plate is rotated with screw-conveyer-shaft
Material is dished out from material discharge port, so that during material is spilled over, the grain and the debris that are intertwined disperse,
Accelerate the separation of grain and material, be so more advantageous to being sufficiently separated grain and debris, separation accuracy higher can be made, and
And separative efficiency higher.
