<P>PROBLEM TO BE SOLVED: To provide a grain discharging apparatus of a combine harvester in which a cleaning port is enlarged evading the strength loss of an auger vertical tube, and the workability of the cleaning and the inspection in the auger vertical tube is improved. <P>SOLUTION: The grain discharging apparatus of combine harvester is characterized as follows. In the combine harvester 1 which includes: an auger vertical tube 9 erected in the backward of a grain tank 4; an auger horizontal cylinder 10 extending from the upper end of the auger vertical tube 9 to the horizontal direction or diagonally to the upper direction; and an auger turning mechanism 11 making the entire of the auger horizontal cylinder 10 and the portion or the whole of the auger vertical tube 9 perform rotation operation by centering on the auger vertical tube 9, when a cleaning port 9a is formed at a portion of the circumference of the auger vertical tube 9 and an attaching and detaching cover 20 covering the cleaning port 9a is provided, a reinforcing member 24 is provided for the right and left both side parts of the cleaning port forming position in the circumference of the auger vertical tube 9, and the top and bottom length of the reinforcing member 24 is lengthened longer than the top and bottom length of the cleaning port 9a. <P>COPYRIGHT: (C)2013,JPO&INPIT |
