Abstract

The invention relates to the technical field of excavators, in particular to an excavator hydraulic system and a method for switching operation modes of a breaker. The excavator hydraulic system includes a hydraulic pump assembly, an actuator and a controller, the hydraulic pump assembly communicates with the actuator, and the controller has an auxiliary operation mode and a non-auxiliary operation mode; in the When the controller is in the auxiliary operation mode, the controller can make the hydraulic pump assembly and the actuator be in a communication state, so that the hydraulic pump assembly can input hydraulic oil to the actuator; When the controller is in the non-auxiliary working mode, the controller makes the hydraulic pump assembly and the executive mechanism disconnected. The invention can effectively control the fuel consumption of the excavator in the auxiliary operation mode.

Description

technical field [0001] The invention relates to the technical field of excavators, in particular to a hydraulic system of an excavator and a method for switching operation modes of a breaker. Background technique [0002] At present, when some excavator operators use the breaker on the excavator for crushing operations in mines or quarries, they often do not select the preset "crushing mode" in the control system, but directly select the "H-heavy load". In order to ensure that the speed of the engine is not lowered and the power output is ensured, the system program controller makes the engine continuously increase the fuel injection amount, and the whole machine is in a state of high fuel consumption. , resulting in high oil consumption of the excavator. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an excavator hydraulic system and a method for switching the operation mode of the breaker, so as to solve the problem that the excavat...
