2. Description of the Related Art Conventionally, in combine harvesters, Shokai Sho 6
As described in Japanese Patent Publication No. 4-13939, a processing chamber having a threshing processing cylinder parallel to the threshing section and a threshing processing cylinder parallel to the threshing section, and after being processed in the threshing section, falls through a rocking sorter to a second gutter. There is provided a reduction product transporter for reducing the processed product to the start end side of the processing chamber, and a reduction processing device is provided for reprocessing the second gutter processed product by the threshing process cylinder.

[0003]

However, since the conventional reduction processing apparatus is configured to reduce the treated product of the second gutter only to the starting end side of the processing chamber, for example, the treated product of the second gutter. There was a problem that even if the crop had a low yield or a crop that would be harmful if reprocessed, it would always be reprocessed by the threshing cylinder.

The main object of the present invention is to make it possible to easily select whether to reprocess or not to reprocess depending on the type of crop to be threshed.

[0005]

In order to achieve the above-mentioned object, the present invention provides a swinging sorting body for sorting a threshing section A and a processed product treated by the threshing section A. 4 and
In the combine reduction processing apparatus including the reduction product transporting body 6 that reduces the processed product that has dropped from the swing sorting body 4 to the second gutter 14, between the reduction product transporting body 6 and the swing sorting body 4. , A processing chamber 8 having a threshing processing cylinder 7 is provided, and the reduced material transporting body 6 is provided with a source-side and front-side inlets 64 that are separated in the transporting direction.
65 is provided so that the front-side charging port 65 communicates with the start end side of the processing chamber 8 and the source-side charging port 64 communicates with the end side of the processing chamber 8 via the shutter 9 and the end side of the processing chamber 8. ,
A discharge port 83 that opens on the rocking sorting body 4 is provided.

[0006]

According to the first aspect of the present invention, by closing the shutter 9, the communication passage from the original inlet 64 to the terminal side of the processing chamber 8 is shut off, and the second trough 14 is processed. ,
Since the reduction product can be returned to the starting end side of the processing chamber 8 from the front input port 65 of the carrier 6, the threshing processing cylinder 7 in the processing chamber 8 can perform the reprocessing. In addition, by opening the shutter 9, the processed material of the second gutter 14 can be returned to the terminal side of the processing chamber 8 from the original input port 64, so that the threshing processing cylinder 7 in the processing chamber 8 reprocesses it. Instead, it can be returned to the upper side of the swing selection body 4 from the discharge port 83 on the terminal side of the processing chamber 8.
Therefore, in the case of a crop that needs to be reprocessed due to a large amount of the processed material falling on the second gutter 14, the shutter 9 can be closed to return it to the starting end side of the processing chamber 8 for reprocessing. In addition, in the case of a crop in which the amount of processed material in the second gutter 14 is reduced, or in the case of which the reprocessing is harmful, the shutter 9 is opened to open the end of the processing chamber 8. Without returning to the side and reprocessing,
It is possible to perform re-sorting with the swing sorting body 4.
