Claims

[Claims for Utility Model Registration] 1. The rear end portion of the upper frame 3 having the drive wheel 1 and the guide wheel 2 and the lower frame 5 supporting the 4 groups of truck rollers can be moved up and down about the rotation fulcrum shaft 6. A relative angle change adjustment mechanism A is interposed between the upper and lower frames 3 and 5 at a portion near the front end of the truck frame F, and when the mechanism A is operated, both frames 3 and 5 are connected to each other. This is a track-travel type combine harvester in which the height above the ground of the vehicle body 7 connected to the upper frame 3 side can be changed and adjusted by changing the relative angle of A vehicle height adjustment device for a track-traveling combine harvester, which is composed of a rotary cam 8, and has an operating part 9 for operating the rotary cam 8, which is located in an upper part away from the ground and in a substantially horizontal direction. 2. An adjustment rod 11 that allows the operation operation section 9 to be detachably attached to a reaping section 10 that is attached to the vehicle body 7 so as to be able to move up and down.
2. The vehicle height adjustment device for a track-traveling combine harvester according to claim 1, wherein the rotary cam 8 of the relative angle change adjustment mechanism A can be operated by the vertical movement of the reaping section 10. 3. A vehicle height adjustment device for a tracked combine harvester according to claim 1) or claim 2), wherein a carrier roller 13 is supported and disposed on an extension of a member 12 that supports the rotary cam 8 of the relative angle change adjustment mechanism A. .
