A discharge support cylinder 36 having a vertical transfer spiral 36a installed therein is provided so as to be pivotable in a substantially vertical posture, and the upper end portion of the discharge support cylinder 36 has its entire length extending in the front-rear length of the combine 1 to the outside of the machine. A discharge auger 37 in which a discharge spiral 37a that discharges is retractably installed is arranged in the front-rear direction so as to be expandable, contractible, vertically rotatable, and horizontally rotatable.

The adjusting plate 8 provided on the upper side of the transfer rack 6a of the rocking / sorting device 5 is maximally adjusted to the right rear part of the adjusting plate 8 which divides the transfer passage into which the threshing processed material is transferred in plan view. At the same time, the right passage 10b of the left / right passages 10a and 10b formed by the partition plate 9 and the adjustment plate 8 which are interlocked and adjusted to the rear end position based on the adjustment of the adjustment plate 8.
The mesh of the Glen sheaves 7a located on the side is a small mesh (a), and the mesh of the Glen sheaves 7a located on the left passage 10a side is a large mesh (b).

As a result, depending on the flow rate of the threshed material, etc.,
Since the width of the transfer shelf 6a can be changed and the layer thickness of the transferred threshing products and the like can be made constant, stable sorting performance can be obtained at all times. When the supply posture is poor and the flow rate is low, such as when handling pillows or laying down, the sorting (silver non-sedimentary grain) is particularly bad, but stable sorting performance is achieved by setting the mesh size to (a). Can be

An adjusting plate 8 is rotatably provided on the upper side of the transfer shelf 6a of the swing selecting device 5, and the adjusting plate 8 is also provided.
A partition plate 9 interlocking with the rotational adjustment of the slide plate is provided slidably on the upper side of the gren sheave 7a.
With the configuration in which the transfer passage transferred on the transfer shelf 6a is divided into two parts to form the left and right passages 10a and 10b, in FIG. As shown, the screen 38 is provided in a wound state, and the screen 38 is moved in accordance with the sliding movement of the partition plate 9a.
At the same time, the take-up stretches and slides and moves,
The end of the screen 38 is attached to the moving boss 30b screwed into the transfer shaft 30a. The wind generated by the rotational driving of the blower blades 31a of the blower 31 is blocked by the screen 38, and is not blown to the large mesh (b) portion of the Glensieve 7a on the left passage 10a side, and the right passage 10b is not blown. This is a configuration in which the small mesh (a) portion of the side grain sheave 7a is ventilated.

As a result, the partition plate 9 and the screen 38 are adjusted based on the adjustment of the adjusting plate 8 of the rocking / sorting device 5 to be divided into the left and right passages 10a and 10b, and the right passage 10b side. Only the threshing-treated products are transferred and swing-sorted, and only the small meshes (b) of the Glensieeve 7a on the right passage 10b side are ventilated by the blower blades 31a of the blower 31. As a result, the sorting performance is improved.
