Abstract

The invention provides a hydraulic system for an excavator and the excavator, and relates to the technical field of control over excavators. The hydraulic system comprises a remote control side, a communication unit, a control unit, a proportional electromagnetic valve and a hydraulic unit; the remote control side is used for generating a control signal; the communication unit is in wireless communication connection with the remote control side, and is used for obtaining the control signal and generating a control instruction according to the control signal; the control unit is in data connection with the communication unit and is used for obtaining the control instruction and generating a driving signal according to the control instruction; the proportional electromagnetic valve is in data connection with the control unit and is used for obtaining the driving signal; the hydraulic unit is in data connection with the proportional electromagnetic valve and is used for executing a corresponding motion according to the driving signal. According to the hydraulic system and the excavator, the flow and direction of the hydraulic system for the excavator can be remotely controlled in a control mode of electric signals; meanwhile, through the proportional electromagnetic valve, all movement units of the excavator can be refinedly controlled, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of excavator control, in particular to a hydraulic system for an excavator and the excavator. Background technique [0002] Excavator, also known as excavating machinery (excavating machinery), also known as backhoe, is an earth-moving machine that uses buckets to dig materials higher or lower than the bearing surface, and loads them into transport vehicles or unloads them into stockyards. The materials excavated by the excavator are mainly soil, coal, sediment, and pre-loose soil and rock. From the perspective of the development of construction machinery, the development of excavators is relatively fast, and excavators have become one of the most important construction machinery in engineering construction. [0003] The hydraulic system of the current excavator is a traditional hydraulic control system. The electrical components only play the role of perception and auxiliary control in the current hydrauli...
