This embodiment is configured as described above, and when performing continuous mowing and threshing work, the mowing grain culm (A) whose culm is cut by the cutting blade (10) is fed by the vertical transport chain (19) to the feed chain ( 7) It is conveyed to the starting end, and when the main switch (72) is turned on, the cut culm supplied to the starting end of the feed chain (7) is transferred to the culm sensor (2).
9) and the culm length is detected by the sensors (31) (32), the solenoids (26) (27) are selectively excited to operate the switching valve (28) appropriately, and the hydraulic cylinder (21). ), The piston rod (22) is moved back and forth to swing and displace the chain (19), and the handling depth is automatically adjusted.
Further, at this time, after a certain period of time has passed since the solenoids (26) (27) have been excited (approximately the time width during which the grain culms are conveyed from the sensor (31) (32) positions to the aligning plate (48) positions) The motor (56) is driven in the forward and reverse directions according to the amount of movement of the transport chain (19), and the aligning plate (48) is adjusted to move left and right to adapt to the actual length of straw culm at this binding position. The stock aligning operation is performed by the aligned plates (48).

When the grain culm sensor (29) no longer detects grain culm, such as at the end of work, the aligning plate (48) moves toward the most root (direction of FIG. 1b) and starts cutting in the next step. This prevents interference between the straw and the alignment plate (48).

The vertical transport chain (19) and the aligning plate (48) may be mechanically linked to each other in the same manner as in the above embodiment, and the aligning plate (48) may be mechanically or It may be configured to be electrically linked. Further, when the vertical transport chain (19) or the handling depth adjusting lever is at the deepest handling position (the chain (19) is in the stored state), the aligning plate (48) may be moved to the most stock position.
Further, even when the stock positions are not aligned during manual handling, the stock aligning plate is located at the most stock position so that the straw does not bend due to interference with the stock plate.

"Effects of the Invention" As is apparent from the above-described embodiments, the present invention is directed to a series of grain culm transport paths (the culm transport route (11), the threshing transport unit (7), and the straw transport unit (34). In a structure in which a straw bundling part (33a) is provided at the rear of 86), and a stock gathering plate (48) that moves and adjusts according to the straw culm length is provided in the bundling part (33a), A grain culm sensor (29) for detecting the presence or absence of grain culm is provided at an appropriate position in the route (86), and the grain culm sensor (2
Since the aligning plate (48) is forcibly moved to the most original position when the grain culm is not detected by (9), the aligning plate (48) is always the most original ( Even if the straw is transported to the bundling part (33a) at the longest culm position, the stock of this straw interferes with the aligning plate (48), causing stagnant jams and bending the straw. Good bundling work can be started without winding or winding, and after that, by moving the aligning plate (48) to the optimum position, it is possible to improve the alignment of the stockholders, which is a remarkable effect.
