Problems solved by technology
[0005] Although the reaping section of the conventional combine harvester can seek to reduce the vibration and noise generated by the cutting device, it is necessary to set a plurality of disc-shaped cutting knives with respect to a raised ridge bar. Depending on the model of the combine harvester, when the cutting width of the cutting device of the harvesting section is different, it is necessary to use cutting knives with different diameters
Therefore, in the harvesting section of the combine harvester, the structure of the cutting device becomes complicated

Embodiment Construction
[0036] Next, an embodiment of the present invention will be described.
[0037] First, the overall structure of the four-row harvesting combine 1 having the harvesting unit 20 according to an embodiment of the present invention will be described. In addition, the harvesting unit related to the present invention is not limited to a four-row harvesting combine, and a multi-row harvesting combine may also be applied.
[0038] Such as figure 1 As shown, the combine harvester 1 is provided with a traveling part 10, a harvesting part 20, a threshing part 30, a sorting part 40, a grain storage part 50, a straw processing part 60, an engine part 70, and a transmission part relative to the machine frame 2. 80 and control unit 90.
[0039] The walking part 10 is provided at the lower part of the machine frame 2. The running section 10 is configured to have a crawler-type running device 11 and the like, and the body can be moved in the forward or backward direction by the crawler-type running...

Provided is a reaping part of a combine in which vibration and noise generated by the cutting device is reduced and the configuration of the cutting device is simplified. In the reaping part of the combine, the cutting device (23) is provided with multiple disc-shaped cutting blades (231) that cut stalks at the base and one disc-shaped auxiliary cutting blade (232) that is configured with a smaller diameter than cutting blades (231) and that cuts the stalks at the base, all blades being rotatable. The multiple cutting blades (231) are arranged on roughly the same line in the left-to-right direction. The auxiliary cutting blade (232) is positioned to the outside of either the right or left outermost cutting blade (231) of the multiple cutting blades (231).
Description
Technical field [0001] The invention relates to a harvesting section of a combine harvester for harvesting grain stalks. Background technique [0002] Conventionally, the harvesting unit of a combine harvester equipped with a cutting device that cuts the pulled up grain stalk has been known. In the harvesting section of such a combine, the cutting device is configured to include a fixed knife and a movable knife extending in the left-right direction as a cutting knife for cutting the grain stalk, and the fixed knife and the movable knife are stacked up and down. In the state, the movable knife cuts the grain stem by sliding the movable knife back and forth relative to the fixed knife. [0003] However, in such a cutting device, there is a problem that large vibration and noise are generated when the grain stem is cut by the fixed knife and the movable knife. Therefore, in order to solve this problem, it has been proposed to use a disc-shaped cutter as a cutter for cutting the gra...
