[0037] On the basis of the above embodiment, the hydraulic pillar 205 cooperates with the transmission support block 502, so that the positioning support 5 supports the hydraulic pillar 205 to pull the adjustment support 2 as a whole to adjust the position, and the adjustment support 2 cooperates with the adjustment pillar 504 to push and pull the adjustment carrier 505 as a whole, so that the adjustment carrier 505 supports a single group of supporting frames 6 to move the position, and the distance between the two groups of supporting frames 6 is adjusted. At the same time, the supporting outer frame 4 and the guide bracket 404 provide stable support for the supporting frame 6 to adjust the load, so that the adjusted load frame 6 cooperates with the installation slot 604 to replace the large excavation side bucket 605, so that the load frame 6 supports the large excavation side bucket 605 to quickly and massively excavate loose geology, so as to improve the excavation efficiency.

[0038] In summary, by supporting the two groups of supporting frames 6 with the supporting support 1 for relative adjustment of their positions, the supporting frames 6 can be equipped with excavation side buckets 605 of different sizes according to the geological conditions, so that a bucket wheel excavator can change the excavation efficiency by changing the structure and installing different types of excavation side buckets 605 according to different geological conditions.
