Abstract
A lid is supported so as to be open and close by swinging upward and downward about a swing axis that is not parallel with the screw axis of a bottom screw.
Claims20
A combine comprising:
- a threshing device configured to thresh a harvested product harvested by a harvesting unit;
- 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 that is provided inside the lower tapered portion and is configured to discharge the threshing product from the threshing tank;
- and
- a threshing discharge device that is connected to the bottom screw and is configured to convey the threshing product from the bottom screw and discharge the threshing product in a body outward direction,
- wherein 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
- wherein 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.
4 more elements
A combine comprising:
- a threshing device configured to thresh a harvested product harvested by a harvesting unit;
- a threshing tank configured to store a threshing product;
- and
- a supply/convey device that extends between the threshing device and the threshing tank, and is configured to supply a threshing product obtained by the threshing device to the threshing tank,
- wherein the supply/convey device includes a conveying case, a drive rotating body arranged inside a lower end portion of the conveying case, a driven rotating body arranged in an upper end portion of the conveying case, an endless rotating body wound around the drive rotating body and the driven rotating body, and a conveying body that is supported by the endless rotating body and is configured to convey the threshing product,
- wherein a support shaft of the driven rotating body is supported by the upper end portion so as to be capable of displacement in a conveying direction,
- wherein the combine further comprises a coupling body that connects two ends of the support shaft, and
- wherein one position adjustment mechanism configured to perform adjustment for changing a position of the support shaft is provided so as to apply position changing force to the coupling body.

A harvester comprising:
- a harvesting unit;
- a threshing device that is provided rearward of the harvesting unit and is configured to thresh a harvest product harvested by the harvesting unit;
- a conveying device that extends rearward and upward from the harvesting unit and is configured to convey a whole culm of the harvest product from the harvesting unit to the threshing device;
- a driver portion provided at a position that is adjacent to a front of the threshing device and above the conveying device;
- and
- a transmission apparatus that is provided at a position that is adjacent to a front of the threshing device and below the conveying device, and is configured to adapt motive power from a drive source and transmit the adapted motive power to a traveling device,
- wherein a manual transmission operation tool configured to instruct a change in a transmission state of the transmission apparatus is provided in the driver portion, and
- wherein a transmission mechanism by which operation force applied to the transmission operation tool is transmitted to the transmission apparatus extends in a horizontal direction between the transmission apparatus and the threshing device.
