Compared with other types excavators, this kind of type excavator used very universal that because has good through theperformance, also may use to lengthens widens as well as the floating type caterpillar band to reduce pressure for the soft ground or the bogregion. The hydraulic excavator main characteristic is: The small and medium-sized hydraulic excavator shovel is the main work device. Hydraulic excavator shovel device by the arm, dou stem bucket, and arm oil cylinder, dou rod oil cylinders, the bucket of cylinder and linkage mechanism. Its structure feature is between components All adopt the connection by oil cylinder hinged adjustable to realize the various movements excavation. Moving arm little hinge point and rotary platform, and with hinged arm oil cylinder to support and change the dip Angle, through arm arm Oil cylinder telescopic can make moving arm around small hinge point lifting rotation. Dou lever arm hinged on the upper arm, dou rod and the relative By dou pole position to control oil cylinder, when dou rod oil cylinder telescopic, dou lever arm can be around the upper energizer hinge point rotation. Bucket and measures Rod front-end loader, and through hinged cylinder telescopic made the bucket turning around the point. To increase the bucket corner, usually by connecting rod Institutions and bucket connection. theperformance good,and may make the high speed reverse, the transmission steady,structure simple, may absorb attacks and vibrates, the operation reduces effort, and to be easy to realize the automated control, is easy to realize the standardization, the seriation, the universalization.This designed main parameter is scoop capacity 0.2m3, it is long to the middle and small scale hydraulic excavator, mainly design the excavator，s the work installment and the hydraulic transmissionprinciple. In the design, used marching walked the installment to satisfied request. Upside the turnplate is the entire rotation , thereof it may work in a greater scope. And further because uses the hydraulicsteering to enable the entire machine performance to improve. Compared with the mechanical type excavator, its excavation strength enhance to 2 ~ 3 times, the entire machine weight approximately is 5 tons,the excavation strength approximately is 30kN, the biggest unloading high approximately is 2.65m, biggest digging depth is 4.2m, the biggest excavation radius approximately is 5.728m, thus can see the entire machine work ability to have the very big improvement, not only excavation strength big, but also machine weight light, transmission steadyly, work efficiency is high, the structure is compact. Moreover, but also proposes to the excavator work installment based on the structureinference organization plan innovation design method.
