Technical Field

The invention relates to the technical field of excavators, in particular to an excavator vibration damping system and an excavator.

Background

The excavator can produce stronger vibration energy at the course of rising and falling of balancing weight at the course of the work to drive the whole quick-witted vibration by a wide margin of excavator, influence the life of excavator, and influence operating personnel's manipulation and experience.

Therefore, a vibration reduction system for an excavator is needed to reduce the vibration of the excavator during operation.

Disclosure of Invention

The invention aims to provide an excavator vibration reduction system which can reduce vibration in the excavator operation process, prolong the service life of an excavator and improve the operation experience of operators.

Another object of the present invention is to provide an excavator which can reduce vibration during work, prolong the service life, and improve the manipulation experience of an operator.

The invention provides a technical scheme that:

the utility model provides an excavator vibration damping system, includes balancing weight, guide, quality piece, elastic component and attenuator, the balancing weight is disposed on the excavator, the guide set up in on the balancing weight, just the guide extends in vertical direction, quality piece slidable ground cover is located on the guide, the elastic component with the respective one end of attenuator with the balancing weight is connected, respective other end along vertical direction extend to with the quality piece is connected.

Furthermore, the side wall of the counterweight block is concavely provided with an accommodating cavity, the guide piece is accommodated in the accommodating cavity, two ends of the guide piece are respectively connected with two side walls of the accommodating cavity opposite to each other in the vertical direction, and the mass block is accommodated in the accommodating cavity.

Furthermore, one end of the elastic piece is connected with the side wall of the accommodating cavity in the vertical direction, and the other end of the elastic piece is connected with the mass block.

Further, the elastic part is a spring, and the spring is sleeved on the guide part.

Furthermore, one end of the damper is connected with the side wall of the accommodating cavity below the accommodating cavity in the vertical direction, and the other end of the damper is connected with the mass block.

Further, the damper is a viscous damper.

Furthermore, a linear bearing is arranged on the mass block, and the mass block is sleeved on the guide piece through the linear bearing.

The invention also provides an excavator, which comprises an excavator body and the excavator vibration damping system, wherein the excavator vibration damping system comprises a balancing weight, a guide piece, a mass block, an elastic piece and a damper, the guide piece is arranged on the balancing weight, the guide piece extends in the vertical direction, the mass block is slidably sleeved on the guide piece, one end of each of the elastic piece and the damper is connected with the balancing weight, the other end of each of the elastic piece and the damper extends to be connected with the mass block in the vertical direction, and the balancing weight is arranged on the excavator body.

Compared with the prior art, the excavator vibration damping system provided by the invention has the advantages that the guide piece is arranged on the balancing weight and extends in the vertical direction, the mass block is slidably sleeved on the guide piece, one end of each of the elastic piece and the damper is connected with the balancing weight, and the other end of each of the elastic piece and the damper extends in the vertical direction to be connected with the mass block.
