Description

Technical Field

[0002] Currently, large hydraulic excavators use various diesel filter mounting structures, and an existing patent (CN217299105 U) also mentions an oil-water separator mounting structure. However, different filtration precision requirements and different emission engine filtration needs lead to the selection of single-stage and dual-stage diesel filters. Currently, the mounting structure is mainly designed based on the filter structure, resulting in a large number of mounting structures for different diesel filters. When different filters are selected for the same vehicle model based on filtration requirements, the mounting structures are not interchangeable, leading to complex installation structures. Furthermore, the frame mounting points need to be redesigned accordingly, resulting in significant waste of parts and design manpower costs. Summary of the Invention
