The invention provides an excavator hydraulic circuit and an excavator, and relates to the technical field of hydraulic circuits. The excavator hydraulic circuit comprises a main pump, a hydraulic oil tank, a first control valve, a second control valve and a first control switch. The first control valve is respectively connected with the hydraulic oil tank and the first actuating mechanism; the second control valve is respectively connected with the main pump and the second actuating mechanism; the second control valve is further connected with the hydraulic oil tank through the first control switch. According to the technical scheme, when the excavator performs composite action, the switch positions among the first control valve, the second control valve and the first control switch are adjusted, and the purposes of saving energy waste, saving fuel oil and improving equipment safety are achieved.
本发明提供了一种挖掘机液压回路和挖掘机，涉及液压回路技术领域。所述挖掘机液压回路包括：主泵、液压油箱、第一控制阀、第二控制阀、第一控制开关；所述第一控制阀分别连接所述液压油箱和第一执行机构；所述第二控制阀分别连接所述主泵和第二执行机构；所述第二控制阀还通过所述第一控制开关与所述液压油箱连接。本发明的技术方案，通过在挖掘机复合动作时，调节第一控制阀、第二控制阀以及第一控制开关之间的开关位置，达到了节省能量浪费，节省燃油以及增加装备安全性的目的。
