DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for treating culms in a threshing machine.

[0002]

2. Description of the Related Art A conventional threshing machine is characterized in that threshing material leaking from a threshing net below a threshing room provided with a handling cylinder pivotally supported on a handling cylinder shaft provided from a starting end to a terminating side of grain culm transfer. And the waste and the like discharged from the waste and waste discharge port provided at the end of the handling cylinder are supplied to a rocking sorting device below the threshing net, and are rocked and transferred while being rocked and transferred. Wind sorting is performed, and the best things such as grains are
Emitted outside the machine. Straw chips and dust are discharged outside the machine.

[0003] The threshed culm passes through the culm passage while passing through the middle partition plate at the beginning of the straw chip discharge port and the lower edge of the culm opening on the rear wall plate at the end of the threshing chamber. In this case, the grain attached to the culm is dropped, but the height of the inner partition plate and the height of the lower edge of the culm opening are the same.

[0004]

The grain culm to be threshed is transported in the threshing chamber from the start end to the end side of the grain culm supply in the threshing chamber, and the grain culm being transported is supported by the handling cylinder shaft. Threshing is threshed by the rotation of the handle, and threshed is discharged from the threshing net below the threshing chamber and from both the waste discharge port at the end of the handle and is shaken. It is supplied to a dynamic sorting device, and the swing sorting device performs the swing sorting and the pressurized air sorting, and the first selected grain or the like is discharged outside the machine and collected. Straw chips and dust are discharged outside the machine.

[0005] The threshed culm passes through the culm passage while passing through the middle partition plate at the beginning of the straw waste discharge port and on the lower edge of the culm opening on the rear wall plate at the end of the threshing chamber. Occasionally, the arboreal kernels that fall into the culm are dropped, but the height of these partitioning plates and the height of the lower edge of the culm opening are the same. In some cases, it is not possible to sufficiently remove the light grain, and the light grain is discharged out of the machine, resulting in a large grain loss. However, this is intended to be solved.

[0006]

According to the present invention, a front wall plate 12 is provided.
a and the back wall plate 12b rotatably support the handling cylinder 19,
The culm supplied from the starting end of the threshing chamber 14 is
