Abstract

The invention discloses a damping device of a mechanical arm of an excavator. 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.

Description

technical field

[0001] The invention relates to the technical field of shock absorption for excavators, in particular to a shock absorption device for a mechanical arm of an excavator. Background technique

[0002] An excavator, also known as an excavator, is an earthmoving machine that uses a bucket to excavate materials higher or lower than the bearing surface, and loads them into a transport vehicle or unloads them to a stockyard. The materials excavated by an excavator are mainly soil, coal, mud Sand and pre-loosened soil and rocks. From the development of construction machinery in recent years, the development of excavators is relatively fast. Excavators have become one of the most important construction machinery in engineering construction. The most important part of excavators Three parameters: operating weight (mass), engine power and bucket capacity. It has been more than 130 years since the first manual excavator came out. The gradual development process of the r...
