Description

Technical Field

[0001] This utility model relates to the field of excavator fuel tank protection technology, and more specifically, it relates to a protective device for excavator fuel tanks. Background Technology

[0002] Excavators, also known as digging machines or excavators, excavate materials mainly such as soil, coal, silt, and pre-loosened soil and rock. They generally consist of a power unit, working device, slewing mechanism, control mechanism, transmission mechanism, traveling mechanism, and auxiliary facilities. The fuel tank is the container on the excavator for storing fuel. During use, the fuel tank often requires protective devices to prevent damage from collisions. Existing protective devices are fixed in place, making replacement cumbersome. Furthermore, the fuel tank is exposed to the elements for extended periods during use, lacking a suitable independent protective mechanism. Additionally, the connection strength between the front and rear housings after assembly needs improvement, as there is a lack of suitable reinforcing connection mechanisms. Utility Model Content
