The damping device comprises a first fixed block, wherein the upper end of the first fixed block is rotatably connected with the front section of a big arm; an excavating device is arranged at the upper end of the front section of the big arm; two second connecting blocks which are parallel to each other are fixedly arranged at one side of the front section of the big arm; second connecting rods are arranged on the two second connecting blocks in a penetrating mode; third connecting blocks are arranged on the secondconnecting rods in the penetrating mode; and ends of the two third connecting blocks are fixedly equipped with the rear end of the big arm. The damping device realizes reducing damages, caused by vibrations generated when a refitted arm of excavator equipment works, on a machine body of the excavator, prolongs the service life of the excavator, and solves violent vibration and the like generated while hitting against a rock; the excavator bears the vibrations for a long time, so that damages on many structures of the machine body are very great, the service life of the excavator is greatly shortened, and faults frequently occur; and the damping device is simple in structure, is convenient for operation, and is suitable for popularization.
