ベルトが地面に対して成す傾斜角が大きくなって泥押し
抵抗が増大し、走行性能が低下しやすかった。However, according to the above-mentioned conventional structure, since all of the plurality of grounding wheels are arranged in parallel with the track frame, the track frame is lowered with respect to the vehicle body frame in a wetland or the like as described above. Sometimes with drive wheels,
The crawler belt between the front grounding wheel located closest to the front of the machine and the crawler belt made a large angle of inclination with respect to the ground, increasing the mud pushing resistance, and the running performance was likely to deteriorate.

ことにある。A characteristic configuration of the present invention is that among a plurality of grounding rollers, a front grounding roller located closest to the front of the machine is supported by the vehicle body frame, and the track frame is supported by the front grounding roller. It is located behind the wheel and the remaining grounding wheels are arranged in parallel with the track frame.

架設されている。The structure for supporting the track frame 17 by the body frame 10 will be described. A pair of front and rear first support shafts 13, 14 are rotatably supported by the body frame 10, and both the first support shafts 13, 14 are rotatably supported. The front ends of the swing links 15 and 16 are fixed to the outer ends of the rocking gears rearward of the machine body. The rear ends of the pair of swing links 15 and 16 are fixed to a pair of front and rear second support shafts 7 and 8 that are rotatably supported by the track frame 17. Actuating arms 21 and 22 are fixed to the inner ends of both the first support shafts 13 and 14, respectively, and a hydraulic cylinder 23 is laid across the actuating arm 22 on the rear side and the vehicle body frame 10. Further, a linking rod 25 is installed so as to extend across both the operating arms 21 and 22.

The front grounding wheel 6 located closest to the front of the machine body is supported by the vehicle body frame 10, the track frame 17 is positioned behind the front grounding wheel 6, and the remaining grounding wheels 6 are placed on the track frame. Since it is arranged in parallel with the vehicle body 17, the inclination angle formed by the crawler belt 9 between the drive wheel 12 and the front grounding roller 6 with respect to the ground changes before and after the descent of the truck frame 17 with respect to the vehicle body frame 10. Therefore, it is possible to prevent an increase in mud pushing resistance when the truck frame 17 is lowered with respect to the vehicle body frame 10 in order to increase the vehicle height in a soft land such as a wetland.
