While being pushed to the side, it is forcibly conveyed backward by the rod tine along the movement trajectory, so that the excreted culm can be brought closer to the tip of the culm body in the conveying process and the stock can be aligned with the guide plate. Then, the stock roots can be temporarily aligned by the stock root alignment device and then sent to the root alignment device. Therefore, the stock roots can be better aligned by the root alignment device.

In addition, even if the amount of waste culm sent from the threshing device to the waste culm transport passage of the binding machine is large, the roots of the waste culm are aligned by the stock rooting device and the root end of the waste culm is forced backward by the rod-shaped tine. Since the culm is conveyed, the culm is not disturbed or clogged in the culm conveyance path.

In addition, since the tine is formed in a substantially semicircular shape protruding in the direction of the tip of the culm in plan view, not only can the strength of the tine be increased, but also the culm can be easily released, and the culm and debris can be removed. It is possible to prevent the straw from being wrapped around the tine or being carried around the tine, so that the effect of always bringing the stock close can be achieved.
