Description
Technical field
This utility model relates to technical field of engineering machinery, particularly relates to a kind of digger arm and excavator.
Background technology
Excavator, as a kind of important engineering machinery, plays an important role aborning.
In prior art, in order to strengthen the intensity of digger arm, on digger arm, patch one piece of reinforcing plate can be welded.Reinforcing plate
Surrounding carry out welding state with digger arm fixed.And weld and terminate to there may be inside rear reinforcing plate big gap, cause work
Bulge after a period of time, thus cause the weld cracking between digger arm and reinforcing plate.
Utility model content
In order to overcome reinforcing plate in prior art that the technical problem of cracking easily and occurs between digger arm, this practicality is new
Type provides a kind of digger arm and excavator.
In order to solve above-mentioned technical problem, this utility model adopts the following technical scheme that
This utility model provides a kind of digger arm, including body, also includes:
Reinforcing plate, is welded in the surface of described body；
Welding hole, is opened in the surface of described reinforcing plate；
Strengthening solder joint, be arranged at position corresponding with described welding hole on described body, described reinforcement solder joint connects described
Body and the inward flange of described welding hole.
Furthermore, it is understood that in described digger arm, described welding hole is strip.
Furthermore, it is understood that in described digger arm, described welding hole is two, two described welding holes are along described reinforcement
The length direction of plate is arranged side by side.
Furthermore, it is understood that in described digger arm, the outer surface of described reinforcing plate is welded with multiple reinforcement, described
Reinforcement is arranged along the length direction of described reinforcing plate.
Furthermore, it is understood that in described digger arm, reinforcement described in two of which is covered each by welding hole described in.
This utility model provides a kind of excavator, including digger arm as above.
The beneficial effects of the utility model are: digger arm of the present utility model, offer welding hole, add inside reinforcing plate
The centre position of big reinforcing plate and the bonding area of digger arm, reduce reinforcing plate and digger arm internal clearance, be substantially reduced
Cracking risk, decreases maintenance cost.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and be embodied as
This utility model is described in detail by example.
Referring to figs. 1 through shown in Fig. 5, this utility model provides a kind of digger arm, including body 1, also includes: reinforcing plate
2, it is welded in the surface of body 1；Welding hole 201, is opened in the surface of reinforcing plate 2；Strengthen solder joint, be arranged on described body 1
The position corresponding with described welding hole 201, strengthens solder joint and connects body 1 and the inward flange of welding hole 201.
Specifically, in digger arm of the present utility model, reinforcing plate 2 is offered welding hole 201, when reinforcing plate 2
After fitting with body 1, the surrounding of reinforcing plate 2 is welded with body 1.Meanwhile, utilize and strengthen solder joint, by welding hole
Inward flange and the body of 201 weld.So, ensure that and there is solder joint between the mid portion of reinforcing plate 2 and body 1
Connect, reduce reinforcing plate and digger arm internal clearance, greatly reduce cracking risk, decrease maintenance cost.
Furthermore, it is understood that as a kind of preferably mode, welding hole 201 is strip.So can guarantee that welding hole 201
The weld length of inward flange so that the reinforcement solder joint of welding is strip, enhances the firm welding journey of reinforcing plate 2 and body 1
Degree.
It addition, welding hole 201 is two, two welding holes 201 are arranged side by side along the length direction of reinforcing plate 2.Set side by side
Two welding holes 201 put add the mid portion of reinforcing plate 2 and the bonding area of body 1, ensure that weld strength simultaneously.
Furthermore, it is understood that in order to increase the reinforcing plate 2 booster action to body 1, the outer surface of reinforcing plate 2 is welded with many
Individual reinforcement 3, reinforcement 3 is arranged along the length direction of reinforcing plate 2.So can increase support force and the stability of reinforcing plate,
Ensure that the bulk strength of digger arm.
In order to ensure that rainwater or impurity enter in welding hole 201, corrosion solder joint or enter reinforcing plate 2 and body 1 it
Between, two reinforcements 3 are covered each by a welding hole 201 so that foreign body or rainwater are not easily accessed in welding hole 201.
This utility model additionally provides a kind of excavator, including digger arm as above.
It should be noted that this excavator is the excavator including above-mentioned digger arm, above-mentioned digger arm embodiment
Implementation is equally applicable in the embodiment of this excavator, also can reach identical technique effect, not repeat them here.
Each embodiment in this specification all uses the mode gone forward one by one to describe, what each embodiment stressed is with
The difference of other embodiments, between each embodiment, identical similar part sees mutually.
In description of the present utility model, it is to be understood that term " longitudinally ", " radially ", " length ", " width ", " thickness
Degree ", " on ", the side that indicates of D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end " " interior ", " outward " etc.
Position or position relationship are based on orientation shown in the drawings or position relationship, be for only for ease of description this utility model and simplification is retouched
State rather than indicate or imply the device of indication or element must have specific orientation, with specific azimuth configuration and operation,
Therefore it is not intended that to restriction of the present utility model.In description of the present utility model, except as otherwise noted, the containing of " multiple "
Justice is two or more.
Above-described is preferred implementation of the present utility model, it should be pointed out that for the ordinary person of the art
