As described above, the reaping section (8) which is mounted in front of the threshing machine so as to be movable up and down and slidably to the left and right is provided with the left and right side dividers (58) as shown in FIGS.
(59) is provided.

Further, as shown in FIG. 9, a body left side divider (60) is provided to be stretched on the left side of the threshing machine, and a telescopic arm (7) for projecting and supporting outward from the front left end of the body.
5) The front end of the fuselage left side divider (60) is attached to the front bracket (76) so as to be rotatable around a vertical axis.
Guide rails (7
7), a ring portion (78) at the rear end of the fuselage left side divider (60) is slidably fitted. In addition, the base end of the arm (75) is connected to the body by the same structure as a vertical positioning mechanism of a right side divider (58) described later, and the arm (75) is lengthened by a lock member (79) provided therebetween. Is set to be stretchable.

The left side divider (58) is extendable and retractable, and its front end is rotatably attached to the left end weeding frame (38) around a vertical axis, and its rear end is the bracket (7).
6) The arm (7) of the side divider (58) (60) which is attached to the front end side of the body left side divider (60) so as to be rotatable about the vertical axis and connected to the left side of the body.
The left and right positions are adjusted by the telescopic operation of 5), and the arm (7) is adjusted.
The vertical position adjustment is performed by the vertical rotation position adjustment of 5).

On the other hand, the right side divider (59) has its front end supported by the right end weeding frame (38), extends obliquely rearward rightward from there, and passes through the lower side of the driver's cab (15) to the right traveling crawler (59). 2), the free end of the right side divider (59), that is, the rear end, is set when the mowing part (8) is located at the right slide end position, as shown in FIG.
As shown in the figure, when the right traveling crawler (2) is protruded further to the right side than the right side and is located near the rightmost side of the threshing machine, and the cutting unit (8) is located at the left slide end position, the right traveling crawler (2) It is located near the right side of 2), and is configured to prevent the right traveling crawler (2) from stepping on uncut kernels at any of the left and right sliding positions.

The left end weeding frame (38) and the center weeding frame (38) have their rear ends at the left end cutting frame (3).
4) and the central cutting frame (34), and the bracket on the weeding frame (38) and the bracket on the cutting frame (34) are joined by a vertical surface and connected by bolts. 1 and 8, the right end weeding frame (38) and the right end cutting frame (34) and the right end cutting frame (34) front end bracket (62) are arranged on a horizontal plane as shown in FIGS. And are connected by bolts (63).

An L-shaped pin (64) is fixed to the upper surface of the middle part of the right end weeding frame (38), and the front end of the right side divider (59) is connected to the pin (6) via a boss (65).
The right side divider (59) is configured to be rotatably supported by the horizontal shaft portion (64a) of 4) and to be able to rotate up and down.

Further, a positioning plate (67) having an arc-shaped long hole (66) is fixed upright on the upper surface of the rear end of the bracket (61) of the right end weeding frame (38), and a right side divider (59). ) An arm (68) is provided to project from the intermediate portion to the rear side of the positioning plate (67), and two bolt shafts (70) (71) are fixed to the tip of the arm (68) via a bracket (69). Then, the bolt shaft (70) on the distal end side is passed through the front surface of the positioning plate (67) to prevent it from being pulled out by the nut (72), and the inner bolt shaft (71) is passed through the elongated hole (66) to prevent the positioning plate from being pulled out. (67) A spring (73) that penetrates the front side and elastically joins the bracket (69) to the positioning plate (67) is provided with an adjusting nut (74) on a bolt shaft (71) projecting toward the front side of the positioning plate (67). Mounting via Preparative (69) and positioning plate (67)
Position at each rotation position of the right side divider (59) by friction with the outer side, and when an external force stronger than that received during weeding is received, the right side divider (59) is inserted into the slot (6).
It is configured to rotate up and down in the range of 6).

The present embodiment is constructed as described above, so that the left traveling crawler (2) does not step on the uncut culm.
The cutting unit (8) is positioned at the left slide end position (solid line position in FIG. 6) to perform a normal cutting operation. During the middle split operation, the cutting unit (8) is moved to the right slide end position (FIG. 6). 4, the solid line position in FIG. 7 and the imaginary line position in FIG. 6) to prevent the crawler (2) from stepping on uncut culm culm and to move the reaper (8) during the ridge cutting operation. Slide to the slide end position on the ridge side to prevent the traveling crawler (2) on the ridge side from climbing on the ridge, and adjust the uncut kernel row by adjusting the left and right sliding of the cutting unit (8). Like that.

Here, as shown in FIG. 7, the right side divider (59) extends to the front of the right traveling crawler (2) by lowering the driver's cab (15) to a height that does not cause an obstacle. When the mowing part (8) is slid to the right during the ridge work with the ridge (A), the right side divider (59) hits the ridge (A) at the same height and is deformed. No. 59) turns upward when hitting the ridge and rides on the upper surface of the ridge (A) so that it does not deform. When the rider rides on the upper surface of the ridge (A), the right side divider (59) is held at that height. However, when the cutting part (8) rises when turning at the end of the ridge (A), the right side divider (59) rises. The right side divider (59) can automatically return to the normal rotation position (height) by the divider (59) rotating downward by contacting the lower surface of the cab (15).

Similarly to the right side divider, the left side dividers (58) and (60) do not deform because they rotate upward when they hit the ridge (A) and ride on the upper surface of the ridge (A).
