Property.
Summary of the invention
The present invention is limited in scope for conventional excavators excavation, excavate that range is excessive and heavy grade on climb and easily cause
The problems such as unstable factor occurs proposes a kind of excavation excavator that range is big and stability is good.
In order to achieve the above object, the present invention is realized using following technical solutions:
It is a kind of to excavate the excavator that range is big and stability is good, including excavator ontology, the excavator ontology include lower part row
Mechanism, fuselage, equipment and counterweight are walked, is connected between the lower running mechanism and fuselage by revolving support, the work
Make to be provided with the first hydraulic cylinder group between device and fuselage, the cylinder barrel and fuselage of the first hydraulic cylinder group are hinged, piston rod top
Portion is fixedly connected with equipment；Counterweight is set to fuselage afterbody, and the second hydraulic cylinder group is provided between counterweight and fuselage,
The cylinder barrel of second hydraulic cylinder group is fixedly connected with fuselage, and piston rod part is fixedly connected with counterweight front.
Preferably, the excavator ontology further includes hydraulic control system, the hydraulic control system includes hydraulic oil
Case is provided with hydraulic pump on the export pipeline being connected with hydraulic tank, and the hydraulic pump other end has pilot control by piping connection
Valve, the pilot control valve other end connect hydraulic oil container by circulation line；Work there are two being also set up on the pilot control valve
Hydraulic fluid port, two actuator ports are separately connected the first hydraulic cylinder group and the second hydraulic cylinder group.
Preferably, two hydraulic cylinders are respectively set in the first hydraulic cylinder group and the second hydraulic cylinder group.
Preferably, there are two the pilot control valves.
Preferably, the underbelly is provided with fuselage bottom plate, hinge seat, first liquid are provided on fuselage bottom plate

Preferably, the hydraulic cylinder of the first hydraulic cylinder group and the second hydraulic cylinder group it is symmetrical side by side respectively and with
Fuselage parallel arrangement.
Compared with prior art, the advantages and positive effects of the present invention are:
1. excavator of the invention separates equipment, counterweight and fuselage, flexible by hydraulic cylinder can be to work
Device and counterweight carry out displacement movement, and equipment is moved back to counterweight while Forward, that is, increase excavation range, and not shadow
The stability for ringing excavator entirety, ground excavation offer that can be very poor to rugged hill path and road conditions very easily operate.
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
To better understand the objects, features and advantages of the present invention, right combined with specific embodiments below
The present invention is described further.It should be noted that in the absence of conflict, the spy in embodiments herein and embodiment
Sign can be combined with each other.
In the following description, numerous specific details are set forth in order to facilitate a full understanding of the present invention, still, the present invention may be used also
To be implemented using other modes described herein are different from, therefore, the present invention is not limited to the specific of specification is described below
The limitation of embodiment.
Embodiment 1, the present embodiment provides the specific structures of excavator.As shown in Figures 1 to 3, the excavator in the present embodiment,
Including lower running mechanism 1, fuselage 3, equipment 2, counterweight 4, lower running mechanism 1 is connect with fuselage 3 by pivoting support,
The first hydraulic cylinder group 8 is equipped between equipment 2 and fuselage 3, the first hydraulic cylinder group 8 includes two hydraulic cylinders, hydraulic
The cylinder barrel of oil cylinder and the hinge seat 9 on fuselage bottom plate 7 are hinged, solid with 6 rear portion of equipment pedestal at the top of hydraulic cylinder piston rod
Fixed connection, is provided with the second hydraulic cylinder group 5 between counterweight 4 and fuselage 3, this group of hydraulic cylinder also includes two hydraulic cylinders,
