Compared with prior art, it the advantages of the utility model and has the active effect that
1. the excavator of the utility model separates equipment, counterweight and fuselage, pass through the flexible of hydraulic cylinder
Displacement movement can be carried out to equipment and counterweight, equipment is moved back to counterweight while Forward, that is, increases excavation model
It encloses, and does not influence the stability of excavator entirety, ground excavation that can be very poor to rugged hill path and road conditions provides very easily
Operation.
2. causing between having between counterweight and fuselage due to being equipped with one group of horizontal hydraulic cylinder between counterweight and fuselage
Every for existing excavator, the center of gravity of counterweight deviates backward, needs to mitigate the overall weight of counterweight to eliminate interval
The influence of unstable factor is brought, thus reduces the material cost of counterweight.

Specific embodiment
In order to be more clearly understood that the above objects, features, and advantages of the utility model, below with reference to specific implementation
Example is described further the utility model.It should be noted that in the absence of conflict, embodiments herein and implementation
Feature in example can be combined with each other.
Many details are explained in the following description in order to fully understand the utility model, still, this is practical
Novel to be implemented using other modes described herein are different from, therefore, the utility model is not limited to be described below
The limitation of the specific embodiment of specification.
Embodiment 1, the present embodiment provides the specific structures of excavator.As shown in Figures 1 to 3, the excavation in the present embodiment
Machine, including lower running mechanism 1, fuselage 3, equipment 2, counterweight 4, lower running mechanism 1 and fuselage 3 are connected by pivoting support
It connects, the first hydraulic cylinder group 8 is equipped between equipment 2 and fuselage 3, the first hydraulic cylinder group 8 includes two hydraulic cylinders, liquid
