The hydraulic excavators and other types of parison, similar to this type of excavator with good performance and the application is wide, the soft land surface or marshy ground area can also use widening, lengthening and floating track to reduce the earth pressure of the. The main characteristics of hydraulic excavator is: can the stepless speed regulation and speed range is very large, can obtain a lower stable rotational speed, fast action, hydraulic ponent motion motion inertia, acceleration performance is very good, and can operate high speed reversal, the transmission is very smooth, very simple structure, can absorb the impact and vibration, laborsaving operation, easy to realize automatic control, easy to realize the standardization, seriation, generalization. This design is the main parameters of bucket capacity of , it belongs to the small hydraulic excavator working device, hydraulic excavator, the main design of transmission principle. In the graduation design, the crawler walking device, in order to meet the requirements of. Upper surface of the turnplate is the entire rotation, therefore it may work in a greater scope. Because of the use of hydraulic transmission and control the overall performance can be improved. Compared with modern excavator, the mining capacity increased to 2 ~ 3 times, the quality is about 6 tons, digging force is about 30kN, the maximum discharge height is about , the maximum digging depth is , maximum digging radius is about , can be seen from the machine operation ability have improved greatly, not only the mining capacity is big, and the 3 weight of the machine, the transmission is steady, the work efficiency is very high, the structure is pact Key word： Hydraulic pressure excavator ； Excavation anization ； Hydraulic system 目錄 摘 要 ......................................................................................................................... 1 ABSTRACT ..................................................................................................................... 2 第一章 液壓挖掘機(jī)的工作特點(diǎn)和基本類(lèi)型 ...
