Then, when the combine is advanced while driving the traveling device 6, the grain culm in the field is cut by the cutting device 9 of the front cutting pre-processing device 11 as the traveling vehicle body 7 advances, and the grain culm transport device 10 Is transported upward by the action of, and is passed to the feed chain 26 and supplied to the threshing machine 8. Then, the culm is held at the head part by the mouth 27 while being transported with the root of the grain held by the feed chain 26.
Is supplied in a state where it is inserted into the handling room 13, and is subjected to threshing by the rotating handling cylinder 12. In this way,
The threshed which has been subjected to threshing is carried around in the handling chamber 13 by the rotating handling cylinder 12, and further leaks from the sorting net while being subjected to the threshing treatment. It reaches 14 and undergoes rocking sorting action.

The objects to be sorted are transferred on the transfer shelf 28 in the direction of the shelves to reach the chaff sheave 29, where the grains and the like leak and are separated and separated from the long straw and the like. At this time, Karamin 15

Further, the dust control plate 32 is controlled in an inclined direction (angle) at which the transfer of the dust is braked when the grain flow rate becomes smaller than the reference value. As described above, the dust adjustment plate 32 automatically performs dust adjustment according to the amount of the second object in the second processing chamber 3 to perform an effective second processing operation.

As described above, the second processing chamber 3 controls the rotation of the second processing cylinder in accordance with the grain flow rate in the room to perform the second processing action according to the actual condition. Dust particles falling into the chamber 1 can be diffused over a wide range, and accurate sorting can be performed without offset on the swing sorting plate 14.
