The invention discloses an energy-saving excavator, and relates to the technical field of excavators. The device comprises a slideway, counterweight iron, a first pulley, a main arm, a main arm shaft pin, a support, a parabolic tower groove, a second pulley and a transmission rope, the counterweight iron is slidably connected to the excavator body through the slide way, the first pulley is mounted at the upper end of the slide way, the main arm is fixed to the parabola-shaped tower groove and rotatably connected with the excavator body through the main arm shaft pin, one end of the transmission rope is fixed to the counterweight iron, and the transmission rope sequentially winds around the first pulley and the second pulley. The other end of the first pulley is connected with the parabola-shaped tower groove, and the first pulley is connected with the main arm shaft pin through a support. According to the energy-saving excavator disclosed by the invention, an upward dynamic moment is generated by a transmission rope through a slide way, a bracket, a pulley and a parabola-shaped tower groove by utilizing the gravity of counterweight iron of the excavator, and the upward dynamic moment is in an equal proportion relationship with a resistance moment; the effects of saving labor and energy are achieved by offsetting a part of resistance torque once and for all.
本发明公开了一种节能型挖掘机，它涉及挖掘机技术领域；它包含滑道、配重铁、第一滑轮、主臂、主臂轴销、支撑、抛物线形塔槽、第二滑轮和传动绳；所述的配重铁通过滑道滑动连接在挖掘机机身上，滑道的上端安装有第一滑轮，主臂与抛物线形塔槽固定，并通过主臂轴销与挖掘机机身转动连接，传动绳的一端与配重铁固定，传动绳依次绕过第一滑轮和第二滑轮，另一端与抛物线形塔槽连接，第一滑轮与主臂轴销之间通过支撑连接。本发明所述的一种节能型挖掘机，利用挖掘机自身配重铁的重力用一传动绳通过滑道、支架、滑轮、抛物线形塔槽产生一个向上的动力矩，且与阻力矩成等比关系；通过抵消一部分阻力矩来实现省力、节能的效果，且一劳永逸。
