BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an oscillating sorting device disposed below a handling cylinder for sorting grains after threshing.

[0002]

2. Description of the Related Art Conventionally, in a threshing machine such as a combine or the like, grains and the like that have been threshed by a handling cylinder and leaked from a crimp net are sorted by a rocking sorter. Wind was performed by the sorting wind, and the fines were returned to the Glen tank, the second was returned to the sorting device, and straw waste and the like were discharged. Then, the chaff of the swing sorting apparatus was disposed to be inclined forward, and the interval between the fins constituting the chaff was constant.

[0003]

However, if the chaff of the swinging sorting device is arranged forward as in the prior art, the sorting accuracy is high in the case of a small number of grains, but the large amount of When the kernels were sent, straw chips and the like were not easily sent to the rear, which reduced the sorting efficiency. In addition, conversely, the chaff portion of the swinging sorting device is arranged rearwardly, the flow of the sorting material becomes faster, and without being sufficiently subjected to sorting,
Sorting is performed coarsely in the front part and culm cuts are easy to mix, sent backward without sorting, stagnation on the second conveyor is likely to occur, and paddy and small straw chips etc. There was a problem that the waste was discharged outside the machine without being sorted out.

[0004]

The present invention is configured as follows in order to solve such a problem. In a sorting device for rocking sorting and wind sorting of grains and the like after threshing, a movable chaff 42 composed of a large number of fins 42a is rotatable around the upper part of the fins 42a so that the inclination can be changed, and the respective fins can be changed. An imaginary line connecting the upper ends of the 42a is formed in a V-shape, and the V-shaped valley is the most conveyer 10a.
Is configured to be located above the.
