The left gear box 7 has a base portion of a left sward mounting rod 10 to which a left sward body 9 is attached at the front end thereof.
The base of the left pulling support rod 12 to which the left pulling device 11 is attached is fixed to the vicinity of the.

The right gear box 8 has a base portion of a right grass attachment rod 14 having a right grass body 13 attached to the front end thereof, and a base of a right pulling support rod 16 having a right pulling device 15 attached to the vicinity thereof. To do.

17a is a left sward cover provided at the rear part of the left sward body 9, 17b is a right sward cover provided at the rear part of the right sward body 13, 18 is a central sward body, and 19a is attached to the left sward mounting rod 10. Left sweep device, 1
9b is a right scraping device attached to the right grass attachment rod 14, 20a is a left star wheel provided on the lower surface of the right scraping device 19a on the base side, 2a
0b is a right star wheel provided on the lower surface on the base side of the right scraping device 19b, 21 is a hair clipper, 22 is a tip carrier device, 23 is a stock carrier device, 24 is an automatic feeding type threshing device 2, and a grain culm. It is a grain culm supply device for supplying.

Then, one of the left and right gear boxes 7 and 8 is attached to the attachment arm 25 by the vertical axis 25a so as to be laterally rotatable with respect to the transmission lateral case 6. In the present embodiment, the left gear box 7 is horizontally rotatably attached to the transmission lateral case 6 laterally.

An engaging hook 26 is attached to the left gear box 7, and the engaging hook 26 is provided on the transmission lateral case 6 side.
The left gear box 7 during the work by engaging with the engaging hole of
Is fixed to the transmission lateral case 6.

Therefore, the left grass body 9 and the left pulling device 11 attached to the left gear box 7 with the vertical axis 25a are
When the left gear box 7 is rotated, it horizontally displaces from a position A in front of the one-dot chain line to a position B on the side of the solid line in FIG. 3, and the left front side of the transmission lateral case 6 and the central grass body 18 are moved. A space portion 28 is formed between and.

(Operation) Next, the operation will be described.

When the machine advances by the traveling device 1, the left bud body 9, the central bud body 18, and the right bud body 13 cultivate the culms that are intertwined on the left and right sides, and the left and right pulling devices 11 and 15 raise the culms and the clippers 21
The root is cut by, and the left and right scraping devices 19a and 19b are scraped, and the tip is conveyed by the tip conveying device 22 to the root by the root conveying device 23 to the grain feeder 24 of the automatic feeding threshing device 2. The ears are supplied to the automatic feeding type threshing device 2 to take over and thresh.

Then, the left sward body 9 is provided by the left sward mounting rod 10, and the left pulling device 11 is provided by the left pulling support rod 12, respectively.
The left gear box 7 is attached to the transmission lateral case 6 by the vertical axis 25a so as to be horizontally rotatable.
When the engaging hook 26 fixing the left gear box 7 and the transmission lateral case 6 is removed from the engaging piece 27, the left gear box 7 can be horizontally displaced.

Then, the left grass body 9 fixed to the left gear box 7
The left pulling device 11 rotates together with the left gear box 7 and is horizontally rotationally displaced from the front A position to the side B position, and the space portion is formed on the left front side of the transmission lateral case 6 and next to the central grass body 18. Forming 28. Therefore, the left and right scraping devices 19a and 19b, the left and right star wheels 20a and 20b, and the left and right pulling devices 11 and 15 can be easily inspected, adjusted, removed of dirt and debris, and replaced easily. The part 3 and the transmission lateral case 6 can be easily attached and detached.

(Effect) Among the above-mentioned known ones, the former is attached so that the entire mowing unit is rotationally displaced between the front position and the lateral position, so that maintenance between the mowing unit and the threshing device can be performed,
No maintenance can be performed between the left and right mulch bodies of the reaping section and the left and right raising devices.

In the latter known example, since the whole is only vertically displaced, the maintenance between the left and right grass bodies of the mowing section and the left and right pulling device cannot be performed in the same manner.

However, according to the present invention, the traveling device 1, the automatic feeding type threshing device 2 provided on the traveling device 1, the right and left grass bodies 9, 13 and the left and right raising devices 11, 15 provided in front of the traveling device 1. And a cutting unit 3 having a hair clipper 21 and left and right scraping devices 19a, 19b
The base is rotatably pivoted to the machine body, and the front end is reaped by the reaping main frame 4 to which the lateral transmission case 6 of the reaping section 3 is fixed, and the left and right rake devices 19a and 19b. In a machine having a carrier for taking over the grain culm to the grain culm supply device 24 of the automatic feeding type threshing device 2, one of the left and right side end portions of the transmission lateral case 6 is provided with a gear box by a vertical axis 25a. It is horizontally rotatably mounted, and one of the left and right grass bodies 9 and 13 and the left and right pulling devices 11 and 15 is located between the front A position and the side B position with respect to the gear box. Since this is a combine harvester mounted so as to be horizontally pivotally displaced, when either of the left and right gear boxes 7, 8 is horizontally pivotally displaced with respect to the transmission lateral case 6, it is fixed to the gear box. One of the left and right grass bodies Causing device, horizontally rotates together with the gear box, since the displacement from the front of the A position to the B position of the side, to form a space portion 28 between the front and central split Sotai 18 of the transmission lateral casing 6.

Therefore, the left and right scraping devices 19a and 19b, the left and right star wheels 20a and 20b, and the left and right pulling devices 11 and 15 can be easily inspected, adjusted, removed of dirt and debris, and replaced easily. The effect that the part 3 and the transmission lateral case 6 can be easily attached and detached can be expected.
