Description

Technical Field

[0001] The utility model belongs to the technical field of excavators, and in particular relates to an excavator covering part. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] The excavator is mainly composed of the power system, hydraulic system, electrical system, working device, upper vehicle system, lower vehicle system and cover assembly, etc. The cover of the excavator is used to modify and enhance the appearance of the whole machine; in complex working environment, the cover of the excavator also plays a certain role in protecting the important parts of the excavator (such as engine, hydraulic system components, pipelines, etc.).

[0004] In order to provide better protection, the strength of the cover needs to be improved. The current method is to set multiple reinforcing ribs on the inside of the cover to improve the strength, but this method will increase the weight of the cover. The excavator cover has a large skin area and thin material, which is prone to deformation. If there are many reinforcing ribs, it will make it difficult to open the hood, and multiple openings will also cause deformation. In addition, the excavator cover also needs to have a heat dissipation function to dissipate the heat generated by the engine when it is working. The current covers often have a heat dissipation structure set at the hood position, but the overall heat dissipation capacity is insufficient. Utility Model Content
