Threshing cylinder

A threshing cylinder comprising:

• a threshing cylinder support shaft that is rotatably provided in a threshing chamber into which the entirety of harvested crops is fed, so as to be oriented along a front-rear direction of the threshing chamber;
• a raking section that is supported by a front portion of the threshing cylinder support shaft and that rakes the fed crops toward a rear of the threshing chamber;
• and
• a threshing processing section that is supported by a portion of the threshing cylinder support shaft located rearward of the raking section and that performs threshing processing on the crops raked by the raking section,
• wherein the threshing processing section comprises:
• a front support member that is supported by the threshing cylinder support shaft;
• a rear support member that is supported by a portion of the threshing cylinder support shaft located rearward of the front support member;
• an intermediate support member that is supported by a portion of the threshing cylinder support shaft located between the front support member and the rear support member;
• a plurality of bar-shaped threshing teeth support members that are supported by the front support member, the intermediate support member, and the rear support member in a state in which the threshing teeth support members extend along the threshing cylinder support shaft and are spaced in a circumferential direction of the threshing processing section;
• and
• a plurality of bar-shaped threshing teeth that are supported by each of the plurality of threshing teeth support members in a state in which the threshing teeth protrude outward in a radial direction of the threshing processing section from the threshing teeth support member and are spaced in a direction extending along the threshing cylinder support shaft,
• wherein each of the plurality of threshing teeth support members is divided into a front-side divided threshing teeth support member located forward of the intermediate support member, and a rear-side divided threshing teeth support member located rearward of the intermediate support member, and
• wherein in a circumferential direction of the threshing processing section, the plurality of front-side divided threshing teeth support members have the same arrangement pitch, the plurality of rear-side divided threshing teeth support members have the same arrangement pitch, and an arrangement of the front-side divided threshing teeth support members and an arrangement of the rear-side divided threshing teeth support members are different, and in the circumferential direction of the threshing processing section, all intervals between the front-side divided threshing teeth support member and the rear-side divided threshing teeth support member adjacent thereto are equal.
