Description

Technical Field

[0001] The utility model relates to the field of excavators, in particular to an excavator cab. Background Art

[0002] Excavator, also known as excavation machinery, also known as backhoe, is an earth-moving machine that uses a bucket to dig materials above or below the bearing surface and loads them into transport vehicles or unloads them to stockpiles. The materials excavated by the excavator are mainly soil, coal, silt, and pre-loose soil and rocks. From the development of engineering machinery in recent years, the development of excavators is relatively fast. Excavators have become one of the most important engineering machinery in engineering construction. The three most important parameters of excavators are operating weight (mass), engine power and bucket capacity. Common excavator structures include power unit, working device, slewing mechanism, operating mechanism, transmission mechanism, walking mechanism and auxiliary facilities. The transmission mechanism transmits the power of the engine to hydraulic motors, hydraulic cylinders and other actuators through a hydraulic pump to drive the working device to move, thereby completing various operations;

[0003] During mining and excavation operations, affected by the working environment and the operator's operating level, the top of the excavator's cab is extremely vulnerable to threats from falling objects such as stones, which can easily cause damage to the top of the cab. Utility Model Content
