[0002]

2. Description of the Related Art Harvesting of standing culm culms with a combine equipped with a thresher is carried out by a reaper provided in front of a traveling chassis of the combine to shave the culmed culms. , It is transferred to the upper rear part by the feed chain of the thresher mounted on the upper side of the traveling chassis and the sandwiching rod, and is sandwiched by these feed chains and the sandwiching rod, and threshed during the sandwiching transfer in the threshing chamber. , Threshed grains, and a part of straw debris are supplied from the threshing chamber to the sorting chamber.

Further, the dust is supplied from the threshing chamber into the dust treatment chamber, is again threshed in the dust treating chamber, and some of the re-threshed grains and straw debris are discharged. It is supplied from the dust treatment chamber to the sorting chamber. Most of the straw that has been threshed is discharged outside the machine. Further, the second one that is not threshed is obliquely installed on the right side of the threshing machine, passes through the second reducing cylinder of the second reducing device through the second discharging cylinder, and is fed back into the second processing chamber. The threshering process is performed again in the second processing chamber, and some of the rethushinated grains and straw waste are supplied from the second processing chamber to the sorting chamber.

The threshing grains supplied from the threshing chamber, the dust treatment chamber and the second treatment chamber into the sorting chamber are subjected to swing sorting and wind sorting. The sorted grains are supplied to the grain storage tank and temporarily stored. In addition, the selected straw waste, shavings, etc. are discharged to the outside of the machine.
