[0002] Excavators, also known as diggers, are used to excavate materials above or below the machine's bearing surface and load them into transport vehicles or unload them into stockpiles. The materials excavated by excavators are mainly soil, coal, silt, and pre-loosened soil and rock. In recent years, the development of construction machinery has been relatively rapid, and excavators have become one of the most important types of machinery in engineering construction.

The mounting bracket 1 is fixedly connected to the mounting shaft 2, and the mounting shaft 2 is connected to the mounting cylinder 3. At the same time, the guide wheel 4 is fixedly mounted on the surface of the mounting cylinder 3 through the adjustment mechanism, and a threaded mounting hole is opened inside the mounting bracket 1, thereby realizing the fixed installation of the guide wheel 4.

[0022] Multiple sets of snap-fit ​​blocks 7 are fixedly installed on the surface of the mounting cylinder 3, and the snap-fit ​​blocks 7 can slide into the interior of the guide wheel 4; the adjustment mechanism includes a sliding plate 8, a trapezoidal block 9, a snap-fit ​​block 2 10 and a screw 11. Multiple sets of screws 11 are rotatably installed inside the mounting cylinder 3. The sliding plate 8 is threadedly connected to the surface of the screw 11. Multiple sets of trapezoidal blocks 9 are fixedly connected to the outside of the sliding plate 8. The snap-fit ​​block 2 10 is slidably connected to the outside of the trapezoidal block 9, and the snap-fit ​​block 2 10 is slidably connected to the interior of the snap-fit ​​block 7. The mounting cylinder 3 is slidably connected to the surface of the snap-fit ​​block 7, and the snap-fit ​​block 7 is fixedly connected to the mounting cylinder 3. The sliding plate 8 is slidably connected inside the mounting cylinder 3. The screw 11 is threadedly connected inside the sliding plate 8, and the screw 11 is rotatably installed inside the mounting cylinder 3. The sliding plate 8 is fixedly connected to the trapezoidal block 9. A T-shaped groove is opened on the outside of the trapezoidal block 9, and the T-shaped groove is slidably snapped with the snap-fit ​​block 2 10. Thus, the guide wheel 4 is fixedly installed by moving the snap-fit ​​block 2 10.

[0023] A gear 12 is fixedly connected to the top of the screw 11. An internal gear disk 13 is meshed with the outer side of the gear 12.
