Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a threshing and grain-supporting apparatus for a combine, and more particularly to an apparatus for increasing the rigidity of a body of a threshing apparatus by supporting the first and second graining machines. .

[0002]

The threshing device is a threshing system in which a spike is passed through a threshing room or a dusting room to the rear while nipping and transporting a root portion of a grain culm by a feed chain or a culling device. Since the processing is performed, the structure is likely to be unstable due to the stalk transport resistance or the like and easily swinging. Such an unstable configuration is reinforced by the configuration of the first and second frying machines.

[0003]

The configuration of the device.

[0004]

The grain culm conveyed by the feed chain 3 is threshed by the rotation of the handle drum 2 in the threshing chamber 4 and is transferred to the culm removing device 5 to convey the dust chamber 7. It is discharged backward. The grains dropped from the threshing room 4 etc. to the sorting room 1 and sorted out are taken out to the Glen tank via the first graining machine 9, and the second grain such as straw waste having the grain is converted into the second graining machine 10. And returned to the second processing room and the like to be threshed. Above the threshing back wall 8 of such a threshing apparatus 11, a main tube 12 is provided along the back and forth direction of the back wall 8, and outside the main tube 12, the first threshing machine 9 and two Since the upper part of the second graining machine 10 and the second graining machine 10 themselves are connected and supported by superposing the upper part with the second graining machine 10 on the inside and outside, the rigidity of the threshing back wall part 8 can be increased. And stable threshing can be maintained, and the configuration can be simplified.
