PROBLEM TO BE SOLVED: To provide a structure for transmission around a grain tank 7 of a combine harvester capable of conveniently performing shaking of the grain tank 7 around a vertically directed shaft Y to the outer lateral side of the machine body without being disturbed with the presence of a transmission passage from an engine 13 to a grain unloading apparatus 8 and further eliminating the need of a conventional structure for automatically separating a driven pulley 35 from a transmission belt 36. SOLUTION: The combine harvester is equipped with the grain tank 7 provided on one side of left and right on a machine frame 2, the engine 13 installed in a site on the front side of the grain tank 7, a vertically directed cylindrical transporting case 10 in a site on the rear side and further the grain tank 7 shaken around the vertically directed cylindrical transporting case 10. In the combine harvester, the structure is composed so as to interlockingly connect an output shaft 25 of the engine 13 and an input shaft 33 provided on the lower side of the transporting case 10 for inputting rotation required for transporting operation of the vertically directed cylindrical transporting case 10 through belt transmission mechanisms 26A and 26B. The input shaft 33 is composed so as to hold a constant relative arrangement relatively to the machine frame 2 irrespective of the shaking of the grain tank 7. COPYRIGHT: (C)2003,JPO
