Then, the combine starts the engine, engages in the threshing clutch, operates the rotating parts of the fuselage to prepare for the work, and stops the threshing work without driving the traveling device. To start. in this case,
As described above, the grain stalks harvested from the headland are manually supplied to the opening end of the transport chain 1 which is open.
While the stock is held and conveyed by the holding rod 2 and the transfer chain 1, the tip portion is supplied to the handling chamber 4 from the handling port and subjected to threshing by the rotating handling cylinder 10. And
Threshing is carried around by the rotating drum 1,
Further, while undergoing the grain-dropping treatment action, it leaks from the sorting net to reach the swing sorting shelf 7 of the sorting chamber 6 and undergoes the swing sorting action.

At this time, the sorting object leaking from the sorting net 18 of the swing sorting shelf 7 is moved to the transfer spiral 8 side most in FIG. 1 because the starting end side of the sorting net 18 is closed. Is restricted, and falls from the tip side to be supplied to the second transfer spiral 12 in a large amount. Further, in the case of the embodiment of FIG. 2, the sorting target that leaks from the sorting net 18 of the swing sorting shelf 7 is in a reduced state as shown by the solid line in FIG. The number of drops to the second transfer spiral 12 increases, and the number of drops to the first transfer spiral 8 inevitably decreases.

Next, the dust control plate 2 of the embodiment shown in FIG.
When the take-up guide 5 is retracted and rotated upward, the inclinations of 3, 23 ', and 23 "are automatically adjusted to the side of applying a transfer resistance to the dust flowing in the handling chamber 4. The dust in the handling room 4 stays in the handling room 4 for a long time, is sufficiently dehulled and supplied to the sorting room 6, and is carefully selected because the amount of the second waste is reduced. You can harvest the first grain.

As described above, at the time of pillow handling, the handling room 4
The amount of cereal culm supplied to the plant is small, and the supply is often intermittent, so that the threshing and sorting operations are not stable, and a large number of secondary products are generated and flow into the transfer spiral most. .
Therefore, each embodiment according to the present invention is configured as described above, and at the time of pillow handling, the amount of grains flowing into the transfer spiral is limited so as to be able to harvest carefully selected grains.
