The combine may include a threshing tank that is configured to store a threshing product obtained by the threshing device and includes a lower tapered portion formed in a bottom portion. A bottom screw is provided inside the lower tapered portion and configured to discharge the threshing product from the threshing tank. A threshing discharge device is connected to the bottom screw and configured to convey the threshing product from the bottom screw and discharge the threshing product in a body outward direction. The threshing tank includes an inspection port formed in a bottom section of the lower tapered portion, and a lid configured to open and close the inspection port, and the lid opens and closes by swinging upward and downward about a swing axis that is not parallel with a screw axis of the bottom screw.

Threshing apparatus

Provided is a threshing cylinder with a threshing processing section provided on the rear side of a raking section. In the threshing processing section, a front support member, an intermediate support member, and a rear support member are supported by a threshing cylinder support shaft. A plurality of front-side divided threshing teeth support members are supported by the front support member and the intermediate support member in a state in which the front-side divided threshing teeth support members are arranged at the same arrangement pitch in the circumferential direction of the threshing processing section. A plurality of rear-side divided threshing teeth support members are supported by the intermediate support member and the rear support member in a state in which the rear-side divided threshing teeth support members are arranged at the same arrangement pitch in the circumferential direction of the threshing processing section.

Threshing cylinder

A combine harvester is provided with: a threshing device that performs a threshing process of threshing a crop; a grain tank that stores grain obtained by the threshing process; a grain discharging device that discharges grain to be stored in the grain tank to the outside of the vehicle body; a travel driving device that drives travel of the vehicle body; and an engine that serves as a power source. The combine harvester includes a first relay shaft to which power is transmitted from an output shaft of the engine, and the power of the engine is transmitted from the first relay shaft to the grain discharging device and the travel driving device in a branched manner.
