(Effects) Conventionally known Utility Model Application Publication No. 61-12337 discloses a combine harvester having a raking reel receiving power transmitted from one power source, an auger, and a first cutting blade, in which the raking reel and the auger are describes a combine transmission system in which the first cutting blade receives power transmission via a clutch (excluding the main clutch). In the known method, the scraping reel and the first cutting blade must be driven in order to rotate the auger, which poses a safety problem. However, the present invention provides a combine harvester having a scooping reel 5 receiving power transmitted from one power source, an auger 8, a first cutting blade 6, and a second cutting blade 17, in which the scraping reel 5
and the first cutting blade 6 is connected to the second cutting blade 1 through the first blade.
7 is configured to receive power transmission through the auger 8 and the second clutch (to), respectively, and the second clutch (to) is configured to be turned on and off in conjunction with the on/off operation of the first clutch. Since it is used as a transmission device for a combine harvester,
Since the second clutch 69 is disengaged in conjunction with the disengagement operation of the first clutch, the harvested grain can be removed while the raking reel 5, first cutting blade 6, and second cutting blade 17 are stopped. The culm can be fed into the auger 8, and the fed grain culm can be fed into the threshing machine M.
This has the effect that the grain can be sent to the third stage for threshing.
