The invention discloses a novel excavator energy-saving device and an excavator, and relates to the technical field of excavators, the novel excavator energy-saving device comprises an excavator body, the other side of the excavator body is provided with a counterweight chamber, the counterweight chamber is internally provided with a counterweight block, the lower part of the counterweight block is connected with a counterweight oil cylinder, and the counterweight oil cylinder is internally provided with a first rod cavity; and a first rodless cavity is formed below the first rod cavity. Compared with an existing device, according to the novel excavator energy-saving device and the excavator, when the gravity of the balancing weight acts on the piston rod in the balancing weight oil cylinder, pressure oil of the balancing weight oil cylinder acts on the second rodless cavity, and the second rodless cavity has upward thrust to offset the downward weight of the movable arm, the bucket rod and the bucket rod; when the excavator works, the balancing weight downwards acts on the piston rod in the balancing weight oil cylinder, so that the balancing weight oil cylinder generates pressure oil to counteract the dead weight of the movable arm, the bucket rod and the bucket rod, redundant power is not needed to load the dead weight of a working device when the excavator works, and therefore energy consumption is reduced, and the purposes of saving energy and reducing consumption are achieved.
本发明公开了一种新型挖掘机节能装置及挖掘机，涉及挖掘机技术领域，包括挖掘机本体，所述挖掘机本体的另一侧设置有配重室，且配重室的内部安装有配重块，所述配重块的下方连接有配重油缸，且配重油缸的内部设置有第一有杆腔，所述第一有杆腔的下方设置有第一无杆腔。该新型挖掘机节能装置及挖掘机，与现有的装置相比，当配重块重力作用在配重油缸内的活塞杆时，使配重油缸压力油作用在第二无杆腔，使第二无杆腔有了一个向上的推力以抵消动臂、斗杆以及斗杆自身向下的重量，当动臂需要向上升时，配重块向下作用在配重油缸内的活塞杆上，使配重油缸产生压力油以抵消动臂、斗杆以及斗杆的自重，使挖掘机工作时无需多余动力负载工作装置自重，从而减少了能量的消耗，达到节能降耗的目的。
