摘要： 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.

摘要： A combine includes a threshing device and a grain tank that is located above the threshing device and stores threshed grain. A threshing cylinder 31 is located in a threshing chamber and rotates about a front-rear axis, and an arc-shaped receiving net extends along an outer circumferential portion of the threshing cylinder 31. A raking unit 33 is located in a front portion of the threshing cylinder 31 and rakes in reaped culm, and a threshing processing unit 34 is located rearward of the raking unit 33 in the threshing cylinder 31 and threshes the reaped culm. A top plate 30 includes a portion that extends from a location corresponding to an upper portion of the raking unit 33 to a location corresponding to an upper portion of the threshing processing unit 34 and that is removable from a main body portion of the threshing device in a body-rearward direction.

摘要： 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.
