Description

[Detailed Description of the Invention] The present invention relates to a combine harvester equipped with a track frame equipped with a pair of running rollers on the left and right sides.

Conventionally, the lower ends of the left and right connecting pedestals installed between the machine base and the truck frame were connected by a pipe member, etc., so the pipe member was located at the center of the bottom surface of the machine base, so that the pipe member It is difficult to wash off the sticky mud, and in wet fields where the truck frame sinks into the mud, the pipe members push the mud, and this mud pushing becomes resistance to running, making it difficult to harvest in the wet fields and making it difficult to drive in the wet fields. When attaching the bridge plate, which is an auxiliary tool, between the left and right truck frames, there are drawbacks such as the shape of the bridge plate being limited by the pipe member.

The present invention solves the above-mentioned conventional drawbacks, and is a combine harvester in which a pair of left and right running rollers is installed on both sides of the bottom of the machine. Left and right connecting frames whose lower ends are respectively connected and fixed to the rear end of the frame are installed in an outward C-shape in the left-right direction of the machine, and the rear end of the track frame is directly fixed to the lower end of the connecting frame, so that the rear end of the running roller is The lower outer side of the connecting frame is extended in the ring-shaped pronunciation, the intermediate part of the connecting frame is bulged out to the outside of the machine to form the frame into an inverted F shape, and an idler tension shaft for adjusting the support position of the idle roller. An idler metal receiver for pivotally supporting the track roller is fixed to the intermediate portion, the idler metal receiver is positioned above the inner ring side of the track roller installed on the track frame, and the idler metal receiver is arranged parallel to the outside of the rear end of the track frame. These were extended and connected,
The machine base can be supported on the gutter rack frame using only the above-mentioned connecting frame, eliminating the need for conventional pipe members, making it easier to clean the lower part of the machine base than before, and reducing the amount of mud pushed when traveling in wet fields. It is possible to improve work efficiency by making the frame smaller, and it is possible to easily attach a bridge plate as necessary between the left and right connecting frames of the outward facing C shape. It is simple and can improve the support strength of the idle roller and track roller, and the positioning of each roller in the left and right direction of the machine can be reliably performed to prevent the running rollers from coming off, and the impact resistance is sufficient compared to the conventional one. It is an object of the present invention to provide a traveling device for a combine harvester, which is easy to handle.
