And threshing by the threshing device 16.

When working on such a combine, a small 2
In the cutting combine, the cutting width is narrow and the cutting device 1 is used in order to prevent the traveling crawler 11 from stepping down the uncut culm.
7, the pre-processing device 5 is moved laterally.
Even if the position of taking over the transported grain culm to the rear grain culm transport section 6 is shifted due to the lateral movement of the grain culm transport section 6, which always tends to return to the left due to the tension of the return spring 8, the pre-processing device 5. By pulling the wire 9 to the right by the connected wire 9, the wire 9 is rotated about the transport support shaft 7 as a fulcrum, and the transport start end 6 is rotated.
b can be moved so as to coincide with the takeover position of the preprocessing device 5.

During the lateral movement of the grain culm transport section 6 by the wire 9, when the transport start end 6 b is out of place due to the influence of the condition of the machine body 20 or the extension of the wire 9,
The positional relationship and the amount of movement can be easily corrected by the adjusting screw 55. In addition, by adopting a simplified mechanism for rotating the grain culm transport unit 6 by the wire 9,
Like the conventional link mechanism or the pin drive mechanism with a long hole, the positional relationship and the amount of movement are fixed in the initial setting state and cannot be adjusted according to changes in conditions, or the mechanism is complicated, so many members are required Therefore, the accumulation of straw chips and weeds is small, and the conveyance passage of the grain stalk is not obstructed.

The position before and after the transfer of the cereal culm to the cereal culm transport unit 6 is kept constant (see FIG. 2). Since the transfer start end 6b of the culm transfer section 6 rotates in an arc shape, the position in the front-rear relationship of the transfer of the grain culm can be changed to prevent a factor that caused spilling, and the transfer performance is stable. At the same time, spilling of the culm can be suppressed.

The upper drive shaft 33 and the connecting frame 35 are coaxially located, so that the structure can be made compact. Also, the pre-processing device 5 can be moved upward by the connecting frame 35 with respect to the linear movement of the lower side. Since the pre-processing device 5 rotates in the front-rear direction by using the laterally moving frame 23 as a support shaft and changes the forward tilt angle, the pre-processing device 5 changes according to the state of the wetland. The tilt angle can be adjusted to respond.
