Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the configuration of an oscillating sorting device which is disposed below the handling cylinder and which sorts grains after threshing.

[0002]

[Prior Art]

 Conventionally, in threshers such as combine harvesters, grains that threshed the culms by the handling cylinder and leaked through the crimp nets are sorted by the swing sorting device, and further, by the sorting wind from the Kara tsubo during the fall. After the wind sorting, the refined grains were returned to the Glen tank, the second ones were returned to the sorter, and the straw debris was discharged. Then, the chaff of the rocking / sorting device is arranged in a forward tilt, and the intervals of the fins constituting the chaff are constant.

[0003]

[Problems to be solved by the device]

 However, if the chaff of the rocking sorting device is tilted forward as in the past, the sorting accuracy is high in the case of a small amount of grain, but if a large amount of grain is sent, it becomes straw. The scraps were not sent to the rear easily, and the sorting efficiency was reduced. In addition, since the fin spacing was constant, the cutouts were easily mixed in the front part, and retention on the second conveyor was likely to occur.

[0004]

[Means for Solving the Problems]

 In order to solve such a problem, the present invention allows a chaff composed of a large number of fins to be pivoted around the upper part of the fins in a sorting device for swing-sorting and wind-selecting grains after threshing. The inclination is changeable, and an imaginary line connecting the upper ends of the respective fins is formed in a V shape.
