Description
Technical field
This utility model relates to a kind of engineering machinery device, the loosening device of a kind of excavator.
Background technology
Traditional exploitation, carrying, the construction operation of smooth decomposed rock, transport after typically taking explosive blasting or flat again
Whole.But, the requirement strengthened safety in production due to current country, the quick-fried strict management and control of explosive control.And the existing main pin of excavator
To excavating the earthwork, loading-unloading vehicle, because its highly versatile, so the weight of the horn of excavator and working range are restricted, from
And the digging force of excavator is restricted, cause and be not suitable for using under the operating mode that some are special.
Therefore, it is necessary to design a kind of new rock arm, to solve the problems referred to above.
Summary of the invention
Creation purpose of the present utility model is to provide a kind of big arm lengths being shortened by rock arm, thus increases excavation
The rock arm of clever activity.
In order to achieve the above object, this utility model adopts the following technical scheme that a kind of rock arm, digs in order to be installed on one
Pick machine, it is characterised in that including a: large arm, one end of described large arm is installed on described excavator；One forearm, be articulated with described greatly
The other end of arm, described large arm with the distance of the hinged place of described excavator to described large arm with the hinged place of described forearm is
5.0~6.0m；One boom cylinder, connects described large arm and described excavator；One bucket arm cylinder, is connected to described large arm with described
Between forearm；One dipper cylinder cylinder head ear mount, is located at the upper end of described forearm；One ridge buster, is articulated with the lower end of described forearm；With
And a bucket cylinder, it is connected between described ridge buster and described forearm.
Further, the overall length of described forearm is 3.7 ~ 4.5m.
Further, the hinged place of described forearm and described large arm is to the distance of described forearm Yu the hinged place of described ridge buster
For described forearm overall length 1/3rd.
Further, the diameter of piston rod of described bucket arm cylinder is more than or equal to 130mm.
Further, the diameter of piston rod of described bucket cylinder is more than or equal to 120mm.
Further, described dipper cylinder cylinder head ear mount is provided with three dipper cylinder cylinder head holes.
Further, the hinged place of described large arm and described boom cylinder to described large arm and described forearm hinged place away from
From for 1.8 ~ 1.9m.
Further, the width of described forearm is 1.7 ~ 2.0m.
Further, the digging force of described ridge buster is 577KN.
Compared with prior art, this utility model have the advantages that described rock arm by by described large arm with
The hinged place of described excavator is 5.0 ~ 6.0m to the distance of described large arm Yu the hinged place of described forearm, thus shorten described greatly
The length of arm, to reach to reduce the load of described boom cylinder, thus increases excavator motility.
[accompanying drawing explanation]
Fig. 1 is the schematic diagram that this utility model rock arm is installed on excavator；
Fig. 2 is the schematic diagram of this utility model rock arm.
The drawing reference numeral explanation of detailed description of the invention:
[detailed description of the invention]
For ease of being better understood from the purpose of this utility model, structure, feature and effect etc., in conjunction with accompanying drawing with concrete
The utility model is described in further detail for embodiment.
As depicted in figs. 1 and 2, rock arm 100 of the present utility model, in order to be installed on an excavator 7, it includes a large arm
1, one end of described large arm 1 is installed on described excavator 7；One forearm 3, is articulated with the other end of described large arm 1；One swing arm oil
Cylinder 8, connects described large arm 1 and described excavator 7；One bucket arm cylinder 2, is connected between described large arm 1 and described forearm 3；One
Dipper cylinder cylinder head ear mount 4, is located at the upper end of described forearm 3；One ridge buster 6, is articulated with the lower end of described forearm 3；And one shovel
Bucket oil cylinder 5, before being connected to described ridge buster 6 and described forearm 3.
Described large arm 1 with distance A of the hinged place of described excavator 7 to described large arm 1 with the hinged place of described forearm 3 is
5.0 ~ 6.0m, thus reduce the load of described boom cylinder 8, increase the motility of described excavator 7；In addition, described large arm 1
It is 1.8 ~ 1.9m with distance B of the hinged place of described boom cylinder 8 to described large arm 1 with the hinged place of described forearm 3, to enter one
Step reduces the load of described boom cylinder 8.Overall length D of described forearm 3 is 3.7 ~ 4.5m, described forearm 3 and the hinge of described large arm 1
The place of connecing is to described forearm 3 and distance C is described forearm 3 overall length D 1/3rd of the hinged place of described ridge buster 6, in this position
Putting is optimal connection distance, utilizes the weight of described forearm 3 upper end to improve the digging force of described excavator 7.
The diameter of piston rod of described bucket arm cylinder 2 is more than or equal to 130mm, and the diameter of piston rod of described bucket cylinder 5 is more than
Equal to 120mm, strengthen described excavator 7 and split the driving force of rock arm 100, thus increase the digging force of described excavator 7 further.
Additionally, described dipper cylinder cylinder head ear mount 4 is provided with three dipper cylinder cylinder head holes 41,42,43, can divide according to on-the-spot regulating working conditions
Not Tiao Jie three dipper cylinder cylinder head holes 41,42,43, except increasing the digging force of described ridge buster 6 so that described ridge buster 6
Digging force reach outside 577KN, it is also possible to increase the excavating radius of described excavator 7；Therefore, by three described dipper cylinders of regulation
Disputer 41,42,43, position, thus increase excavator 7 power and excavating radius so that it is more flexible is applicable to various construction work
Condition.
The width E of described forearm 3 is 1.7 ~ 2.0m, thus the body structure strengthened, pour into more inside body structure
Concrete and iron ore, increase the own wt of described rock arm 100, utilize described rock arm 100 self weight improve institute
State the digging force of excavator 7.
Detailed description above is only the explanation of the preferred embodiment of this utility model, and non-therefore limitation this utility model is specially
Profit scope, so, all utilization this creation description and the equivalence techniques change for it of diagramatic content institute, it is both contained in this creation specially
In the range of profit.
