By extending the position to a position that can be transported to a position close to the merging position of the cereal, the upper part of the culm can be transported to the rear in a stable posture in the process of conveying the harvested cereal. There is an advantage that the disturbance can be minimized.

Next, an embodiment will be described based on FIG. 6 with respect to the star wheel transmission of the multi-row mowing and conveying apparatus 18.
In this type of multi-row harvesting combine, a cutting and conveying device equipped with a stir-up star wheel is formed by engaging adjacent stir-up star wheels to simplify the transmission mechanism. A known technique is known in which a wheel is provided with a transmission function in addition to the action of stirring the grains. For example, Japanese Patent Application Laid-Open No. 2004-57091 and Japanese Patent Application Laid-Open No. 2006-197807 disclose a transmission device that engages a star wheel.

  First, as shown in FIG. 6, in the embodiment, a driving star wheel 44 is transmitted via a root conveying chain 43 from an intermediate driving sprocket 42 that is driven by taking out rotational power from the rear frame 3. Both the stirrer star wheels 45 and 46 meshing with the stirrer star wheel 44 from both the left and right sides are transmitted. Then, as shown in the drawing, the driven star wheel 46 is configured to transmit a root conveying device 47 for one line.

  In this way, in the embodiment, the rotational power extracted from the rear frame 3 is configured to transmit a total of three conveying devices starting from the drive sprocket 42 in the intermediate portion, thereby simplifying the transmission mechanism. However, there are also advantages such as eliminating traps by eliminating the transmission shaft. And since the Example employ | adopted the star wheel transmission in the structure which has arrange | positioned the corn straw scraping device 8 for 1 row | line | column between 1 set of 2 pieces of corn straw scraping devices 7 and 7 on either side, respectively. There is an advantage that the number of parts can be reduced without adding a transmission device.

  In the embodiment, as shown in the drawing, three series of staring star wheels 44, 45, 46 are sequentially meshed, and the central staring star wheel 44 is used as a driving star wheel. Since the wheels 45 and 46 are driven star wheels, they are characterized in that they are stronger in strength and have little play due to transmission as compared with the known technology already described.

  In addition, the said Example is the structure which has arrange | positioned the grain stalk scraping devices 7 and 7 for two strips on both right and left sides, and has arrange | positioned the grain stalk scraping device 8 for one strip | interval in the meantime. A configuration is employed in which power is transmitted from the star wheel 44, but it is also possible to employ a configuration in which this is input from the stir-in star wheel 48 on the left side.

  In this case, if the staring star wheel 46 meshes with the staring star wheel 48 and is transmitted, it is necessary to consider that the rotational direction and the direction in which the culm is taken are matched.
