(C) Problems to be solved by the device However, the culms (54) threshed by the threshing screw rotor (53) of the threshing unit (50) are sequentially transferred backward only by the rotation of the screw rotor (53). Therefore, the culm (54) is discharged to a position on one side of the machine body and to a position immediately after the traveling crawler (55), and the culm is discharged. If it gets clogged on the way, the passage of the sorting wind will be blocked and it will not come out to the rear. Therefore, the grain in the threshing chamber cannot be reliably sorted, and the threshing work cannot be performed efficiently.

(D) Means for Solving the Problems In the present invention, in the ordinary combine harvester in which the culm treatment chamber is provided behind the threshing treatment chamber and culms are discharged through the culm treatment chamber, In addition, a culm carrier device for laterally conveying and discharging the culm from the left and right sides of the machine body toward the culm discharge opening formed on the center side of the machine body is provided. A guide plate for guiding the laterally discharged culm is provided at a position immediately behind the air guide, and a wind vent passage is formed between the guide plate and the outer wall of the machine body. Does not provide a structure for the culm treatment chamber in a normal combine, characterized in that the lower part of the air vent passage is opened directly below the machine body while communicating with and through the opening formed in the upper part of the guide plate. It is what

As described above, according to the present invention, in the ordinary combine harvester in which the culm processing chamber is provided behind the threshing processing chamber (4-1) and the culms are discharged through the culm processing chamber (18-1). , A culm transport device (17-1) is installed in the culm processing chamber (18-1),
Since the ventilation system (17-1) is provided with a wind vent passage (47-1), the culms that pass through the culm processing chamber (18-1) are transported augers (22-1), etc. Since the culm carrier device (17-1) having the above structure can forcibly convey the culm to the center of the machine and drop it, the culm will not be blocked in the middle.

Then, the sorted wind passing through the culm treatment chamber (18-1) is discharged through the wind vent passage (47-1) provided in the culm conveying device (17-1), so that the sorted wind passes through. Is improved, the sorting accuracy of grain culms is improved, and the sorting wind discharged downwards through the air passage (47) acts as an air curtain, and from the culm opening (23-1). Since the discharged culm and dust can be guided while being blown toward the ground surface, it is possible to reliably prevent the culm and dust from soaring upward.
