A reduction processing apparatus is provided.
[0003]
[Problems to be solved by the invention]
However, since the conventional reduction processing apparatus is configured to reduce the second processed material only to the starting end side of the processing chamber, for example, a crop that reduces the second processed material, or In the case of crops that would be harmful if reprocessed, there was a problem that they would always be reprocessed in the threshing cylinder.
[0004]
The main object of the present invention is to enable easy selection between reprocessing according to the type of crop to be threshed and the case without reprocessing.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a threshing portion, a rocking sorter that sorts the processed material processed in the threshing portion, and a treated material that has fallen from the rocking sorter to the second basket. A reduction product transport body that returns to a processing chamber in which the threshing processing cylinder is rotatably accommodated, and the threshing processing cylinder is a combine in which a spiral, a processing blade, and a discharge blade are sequentially provided in the direction of the rotation center line. In the processing chamber, the helix of the threshing treatment cylinder is located on the front side of the threshing part, and the discharge blade is located on the rear side of the threshing part. The reductant transport body has a front-side input port that communicates with the start end side of the processing chamber and a source-side input port that communicates with the upper end side of the processing chamber via a shutter. The discharge opening on the swing sorter at the lower end side of the processing chamber Characterized in that a is provided.
[0006]
[Effects of the invention]
In the present invention, by closing the shutter, the communication path from the original inlet to the terminal end of the processing chamber is blocked, and the second processed material is transferred from the front inlet of the reductant carrier to the processing chamber. Since it can reduce | restor to the start end side, it can reprocess with the threshing processing cylinder in this process chamber. Also, by opening the shutter, the second processed material can be reduced from the original inlet to the terminal side of the processing chamber, so that the processing chamber end side is not reprocessed by the threshing cylinder in this processing chamber. It can be reduced from the outlet to above the rocking sorter. Therefore, in the case of a crop that needs to be reprocessed due to a large amount of processed material falling to the second pot, it can be returned to the start end of the processing chamber and reprocessed by closing the shutter. In addition, in the case of crops that reduce the amount of processed material in the second row, or crops that would be harmful if reprocessed, the shutter is opened to return it to the end of the processing chamber for reprocessing. It can be re-sorted with a rocking sorter without processing.
