Excavator mechanical arm with damping function

Abstract

The invention discloses an excavator mechanical arm with the damping function. The excavator mechanical arm comprises a supporting arm main body, a bucket rod oil cylinder, a bucket rod hydraulic rod, a fixed shaft, a power arm, an elastic bandage, a power oil cylinder, a power hydraulic rod, a bucket oil cylinder, a bucket hydraulic rod, a fixed supporting rod, a damping spring, a rotating shaft rod, a bucket rod arm, a bucket, bucket teeth and a fixed rotating shaft. The excavator mechanical arm has the beneficial effects that the damping spring is arranged between the bucket oil cylinder and the bucket rod arm, and therefore the vibration effect generated on an excavator can be effectively reduced when the excavator mechanical arm works, the service life of the mechanical arm is prolonged, and the maintenance cost is saved, the purchase cost is saved; as for the transmission effect, the power transmission is realized through interaction of the oil cylinders and the hydraulic rods, and the work efficiency, the safety and the working capability are effectively improved; and the bucket teeth are arranged, so that excavation is convenient. In addition, the excavator mechanical arm is simple in structure, low in cost and suitable for being popularized and used.

Description

technical field [0001] The invention relates to a mechanical arm device, in particular to an excavator mechanical arm with a shock absorbing function, and belongs to the application field of mechanical products. Background technique [0002] A robotic arm is a mechanical device that can automatically complete object transmission or operation operations according to established procedures or requirements, and it can partially replace human manual labor. [0003] At present, when the existing mechanical arms on the market are used in industrial machinery, such as excavators, the mechanical arm will bear a large gravity during work, which will cause the vibration of the mechanical arm. On the one hand, the vibration will affect the work efficiency, and on the other hand, it will There may be hidden safety problems, and the service life will be reduced. The maintenance price is relatively expensive, and the economic loss is relatively serious. Therefore, in view of the above pr...
