SUMMARY OF THE INVENTION The above-mentioned JP-A-3-23
In the combine described in US Pat.
At the middle position in the vertical direction between the body and the crawler frame,
Frame shape supporting the rear support shaft, which is the rotation axis of the link mechanism
Intermediate frames exist.

[0005] The intermediate frame is connected to the front support shaft.
From the arrangement position to the rear support shaft arrangement position in the front-rear direction
Front link mechanism formed long and provided on both left and right
And wider in the lateral direction for supporting the rear side link mechanism
Is formed. Therefore, the existence of this intermediate frame
To maintain the vehicle body in the set position in the left, right, front and back depending on
The structure that makes up the mechanism increases, and the weight increases.
Crawler type traveling equipment easily sinks in wet fields etc., hindering traveling.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A combine vehicle body 2 is composed of a frame of vertical and horizontal frames, and a pair of right and left crawlers 1 is provided on a lower side.
Crawler frame 8 is a pair of front and rear parallel links 9,1
0 (the front link mechanism 9 and the rear link mechanism 10) are supported so as to move up and down in parallel. Rollers are arranged on the crawler frame 8, and the crawler 1 is wound around the drive sprocket of the traveling transmission case. Numerals 11 and 12 denote support shafts (front support shaft 11 and rear support shaft 12) of the parallel links 9 and 10 with respect to the vehicle body 2 side bracket, and the front and rear parallel links 9 and 10 are link arms 14 integrated with these. 15 (front link mechanism 14, rear link
The link mechanism 15) is connected by a rod 13, and a rear link arm 15 is provided between the rolling cylinder 1 and the vehicle body 2.
6 and the left and right rolling cylinders 16L and 16L
R is operated separately for each. When it is extended by hydraulic pressure, it moves down the parallel links 9, 10 to push up the vehicle body 2, and when it is shortened, it acts to descend.
As a result, the left and right rolling cylinders 16L, 16L
The vehicle body 2 rolls to the left or right due to the difference in the amount of elevation by R. Although the rolling control can be performed manually, the horizontal control is automatically performed by detecting the left-right inclination of the vehicle body 2 using a horizontal sensor in the left-right direction.

A pair of left and right pitching arms 17 are pivotally supported on a lower part of the vehicle body 2 around a support shaft 18. The pitching arm 17 is connected to a left and right bifurcated arm 20 by a connecting shaft 19 via a front and rear support shaft 12. The upper end of the right pitching arm 17R is protruded upward from the vehicle body 2 and a hydraulically expandable and contractable pitching cylinder 6 is connected between the upper end and the vehicle body 2. By
The vehicle body 2 is configured to be able to swing up and down around a front support shaft 11. The support shaft 1 of the parallel link 10 with respect to the vehicle body 2
The two parts are configured to be supported by the support shaft 12 on such an arm 20.

The left and right pitching arms 17 and the vehicle body 2
Each of the right and left rolling cylinders 16 is connected to a rotating piece 21 pivotally supported by the link 22 by a link 22.
The front end of the left and right rolling cylinder 16 is connected to a connecting pin 23 between the rotating piece 21 and the link 22 so that the front end of the right and left rolling cylinder 16 is substantially along the upper surface 2 to form a connecting portion to the vehicle body 2.

The pitching control is carried out by manual operation or automatically by the pitch angle of the pitching cylinder 6 by the inclination angle of the front-rear horizontal sensor for detecting the inclination of the vehicle body 2 in the front-rear direction. Alternatively, the control is maintained at a constant inclination angle. On the upper side of the vehicle body 2, the left crawler 1
The threshing device 4 is mounted above the L side, and the Glen tank 5 is mounted above the right crawler 1R side. The Glen tank 5 forms a space 7 extending in the front-rear direction between the threshing device 4 side and the lower vehicle body 2 by inclining the bottom portion 24, and threshing the space portion 7 on the threshing device 4 side. A fryer 25 that takes out the grains and transports them to the Glen tank 5 is provided.

At the rear end of such a Glen tank 5,
A discharge auger 26 for taking out and transporting the kernels is erected, and the Glen tank 5 can be turned outward with respect to the discharge auger 26 about an adjacent rotation shaft 27.
The space between the side surfaces of the threshing device 4 and the Glen tank 5 itself can be largely opened. As a result, cleaning of the space 7 and maintenance of each part can be facilitated.

At the front of the body 2, a mowing device 3 is supported in a vertically movable manner in front of the threshing device 4, and the mowing culm is transferred and supplied to the feed chain 29 of the threshing device 4 for threshing. In addition, an engine, a steering device 28, and the like are mounted in front of the Glen tank 5.
