Description
Technical field
The utility model relates to a kind of scraper bowl rocker arm bodies of excavator.
Background technique
Excavator is the indispensable engineering machinery of modern society, and with advancing for society, people are to excavator
Technical requirements are also higher and higher, and the scraper bowl digging force for specially requiring excavator is increasing.In the prior art, the scraper bowl of excavator
Oil cylinder rocker arm (swing arm) is all straight-arm form, and two ends of straight-arm have axis hole, a termination dipper of straight-arm, and another termination scraper bowl pushes away
Bar.The connection of the cylinder rod of scraper bowl push rod and bucket cylinder, bucket cylinder directly passes through scraper bowl push rod and scraper bowl is pushed to excavate, in this process
In, existing two hole rocker arm is only played a supporting role.It is disadvantageous in that existing for the rocker arm of existing two hole, bucket cylinder needs very
Big stroke could shift scraper bowl onto position, there is a problem of that digging force is small, excavation speed is slow.
Utility model content
The purpose of the invention of the present invention is to provide a kind of scraper bowl rocker arm body of excavator, scraper bowl can be effectively shortened
Oil cylinder stroke increases digging force, improves excavation speed.
Realize the technical solution of the present utility model purpose:
The lower end axis hole of a kind of scraper bowl rocker arm body of excavator, scraper bowl end earrings and dipper is hinged, ear in the middle part of scraper bowl
The lower end axis hole of ring and scraper bowl push rod is hinged, bucket cylinder is equipped with, for driving scraper bowl to overturn, it is characterised in that: is equipped with rocker arm
Swing rod is respectively equipped with three work axis holes, three work axis hole settings triangular in shape, the third working shaft of rocker arm swing rod above
The lower axle bore of hole and dipper is hinged, and the upper end axis hole of the first work axis hole and scraper bowl push rod of rocker arm swing rod is hinged, scraper bowl oil
The piston rod earrings of cylinder and the second work axis hole of rocker arm swing rod are hinged.
Further, rocker arm swing rod is in 7 fonts, and three vertex of respective rocker arm swing rod are respectively equipped with three work axis holes,
Three work axis hole settings triangular in shape；The piston rod earrings of bucket cylinder is put by the work axis hole of rocker arm swing rod second and rocker arm
Bar is hinged；Described second work axis hole is corresponding with rocker arm swing rod intermediate vertex.
Further, rocker arm swing rod is arc-shaped, is set on rocker arm swing rod there are three the axis hole that works, three work axis holes are in triangle
The piston rod earrings of shape setting, bucket cylinder is hinged by the work axis hole of rocker arm swing rod second and rocker arm swing rod；Described second work
Making axis hole is axis hole in an intermediate position.
The utility model has the advantages that
The utility model shakes equipped with rocker arm swing rod, is respectively equipped with three work axis holes above, and three work axis holes are in three
Angular setting, rocker arm swing rod third work axis hole and dipper lower axle bore it is hinged, rocker arm swing rod first work axis hole with
The upper end axis hole of scraper bowl push rod is hinged, and the piston rod earrings of bucket cylinder and the second work axis hole of rocker arm swing rod are hinged.This reality
With being set on Novel rocker arm swing rod there are three the axis hole that works, rocker arm swing rod not only acts as supporting role, and plays driving effect, i.e.,
Bucket cylinder pushes bucket rod of bucket by rocker arm swing rod, so that scraper bowl generates overturning.Since distinctive three hole of the utility model is shaken
Arm swing rod structure enables the utility model to effectively shorten bucket cylinder stroke, increases digging force, improves excavation speed.With
The prior art is compared, and the utility model can shorten bucket cylinder stroke length 1/5th or so, the scraper bowl digging force of excavator
1/5th or so can be increased, the excavation speed of scraper bowl can accelerate 1/5th or so, while also reach the in-oil cylinder liquid of reduction
Oil pressure, fuel-economizing effect.
The utility model rocker arm swing rod is in 7 fonts or arc, and three vertex of respective rocker arm swing rod are respectively equipped with three works
Make axis hole, three work axis hole settings triangular in shape；The piston rod earrings of bucket cylinder passes through the work axis hole of rocker arm swing rod second
It is hinged with rocker arm swing rod.Three work axis holes of the utility model rocker arm swing rod are not at same straight line, further ensure contracting
Short bucket cylinder stroke increases digging force, improves the effect of excavation speed.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is that the utility model scraper bowl is in the schematic diagram under excavation state.
Specific embodiment
Embodiment one:
As shown in Figure 1,1 front end of swing arm and dipper 2 are hinged, it is correspondingly provided with bucket arm cylinder 3, bucket cylinder oil cylinder 3 is for driving bucket
Bar 2 rotates.8 end earrings of scraper bowl and the lower end axis hole of dipper 2 are hinged, the lower end axis hole of scraper bowl 8 middle part earrings and scraper bowl push rod 5
Hingedly, it is equipped with bucket cylinder 7, for driving scraper bowl 8 to overturn, this is the prior art.
Equipped with rocker arm swing rod 4, it is respectively equipped with three work axis holes above, three work axis hole settings triangular in shape are shaken
The lower axle bore of third the work axis hole and dipper 2 of arm swing rod is hinged, the first work axis hole and the scraper bowl push rod 5 of rocker arm swing rod
Upper end axis hole is hinged, and the piston rod earrings of bucket cylinder 7 and the second work axis hole of rocker arm swing rod 4 are hinged, phase in the axis hole that works
Articulated shaft 6 should be equipped with.In the present embodiment, rocker arm swing rod is in 7 fonts, and three vertex of respective rocker arm swing rod are respectively equipped with three
Work axis hole, three work axis hole settings triangular in shape；The piston rod earrings of bucket cylinder passes through the second working shaft of rocker arm swing rod
Hole and rocker arm swing rod are hinged；Described second work axis hole is corresponding with rocker arm swing rod intermediate vertex.
As shown in Figure 1 and Figure 2, when work, bucket cylinder 7 pushes scraper bowl push rod 5 by rocker arm swing rod 4, and scraper bowl 8 is driven to turn over
Turn, to effectively shorten bucket cylinder stroke, increases digging force, improve excavation speed.
Embodiment two:
Embodiment two and the difference of embodiment one are that rocker arm swing rod is arc-shaped, the same embodiment of remaining structure, working principle
One.
