[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a configuration for efficiently performing wind selection by a Kara Minou fan of a threshing device.

[0002]

[Prior Art]

 Conventionally, in threshing devices such as combine harvesters, grains that have been threshed by the handling cylinder and leaked through the crimp net are sorted by the swing sorting device, and further, in the middle of falling, sorting is performed by the sorting wind from Kara The technology is well known.

[0003]

[Problems to be solved by the device]

 However, if the configuration is such that wind selection is performed when falling from the rocking sorting device as in the past, if a slightly damp grain or the like falls, retention easily occurs in the chaff front part of the rocking sorting device. In addition, when a large amount of grains fell, straw chips and the like tended to be mixed in the first product, and the second product also increased, resulting in a decrease in processing capacity.

[0004]

[Means for Solving the Problems]

 In order to solve such a problem, the present invention proposes a sorting device for swinging and wind-selecting grains after threshing, in which a chaff and a Glensive are placed in front of the swinging sorting device arranged below the handling cylinder. A guide plate for guiding the sorting air is arranged between them, and openings for blowing the sorting air from the Kara-moh are provided at the introduction part to the guide plate and the introduction part between the gren sieve and the first conveyor. ..
