Description
Technical field
The present invention relates to mechanical field, specifically a kind of excavator that side coil can be excavated.
Background technology
Excavator, also known as excavation machinery, is to be excavated higher or lower than the material holding machine side with scraper bowl, and loads haulage vehicle
Or unload to the earthmoving machinery of rickyard.The material that excavator excavates is mainly soil, coal, silt and the soil after pre- pine
And rock.From the point of view of the development of engineering machinery in recent years, the development of excavator is relatively fast, and excavator has become as engineering construction
In one of topmost engineering machinery.To divide according to scraper bowl, excavator can be divided into forward shovel, backacter again, draw
Shovel excavator and clam shell excavator.Forward shovel is used for excavating the material of more than earth's surface, and backacter is used for excavating
Material below earth's surface.It is modal that backacter backhoe type is that we met, and backward downwards, forces to cut soil, can be used for
Shut down the excavation of below the scope of operation, elemental operation mode has：Ditch end is excavated, ditch side is excavated, straight line excavates, curve excavates, holding
Certain angle excavation, super deep trench excavation and the excavation of ditch slope etc..Forward shovel shovel soil action form, be characterized in " advance to
On, force to cut soil ".Crowd shovel digging force is big, can excavate the soil in more than shutdown face, preferably be used for excavation height and base is dried more than 2m
Hole, but must setting up and down ramp.The bucket of the excavator of backhoe than same equivalent for the bucket of crowd shovel is larger, can excavate water content
It is not more than 27% one to three class soil, and completes entirely to excavate hauling operation with dump truck cooperation, large-scale drying can also be excavated
Foundation ditch and mound etc..The digging mode of face shovel is different from the relative position of haulage vehicle according to excavating route, cuts the earth
With unload soil mode have following two：Positive shoveling, laterally unloads soil；Positive shoveling, reversely unloads soil.
According to above-mentioned classification, present excavator is all one of mentioned kind, when construction site needs crowd shovel to excavate
A forward shovel must be looked for during machine, a backacter when needing backacter when construction site, must be looked for, when need
It is necessary to two different excavators are being constructed when to be used alternatingly, this is because the unicity of excavator function makes
Construction cost increases, and the service efficiency of separate unit excavator is relatively low, and the rotation of current big arm of digger, forearm and scraper bowl is all
At grade, dead ahead can only be excavated, spatial degrees of freedom is relatively low.
Content of the invention
The present invention is directed to the deficiencies in the prior art, provides a kind of excavator that side coil can be excavated.
To achieve these goals, present invention employs technical scheme below：
The excavator that side coil can be excavated, including base, large arm, middle arm, rear forearm, front forearm, scraper bowl, second
Expansion link, support stake, jack, the 3rd expansion link, the 4th expansion link, bracing frame, sliding sleeve, the first expansion link, scraper bowl pull bar with
And scraper bowl pole,
Large arm one end is passed through rotation pair one and is connected on base, and the large arm other end passes through rotation secondary three and middle arm one end connects
Connect, the middle arm other end is passed through rotation secondary four and is connected with rear forearm one end, and the rear forearm other end passes through to rotate secondary five and front forearm one
End connects, and the front forearm other end passes through rotation secondary six and is connected on scraper bowl, rotates secondary three Plane of rotation and the rotation of rotation secondary
Turn plane vertically, the Plane of rotation rotating pair five is vertical with the Plane of rotation rotating secondary four,
Described base is provided with the groove of vertical direction, and bottom portion of groove is provided with jack, supports stake to install in a groove
On jack, second expansion link one end is passed through rotation secondary seven and is connected in support stake, and the second expansion link other end passes through to rotate pair
Eight are connected in large arm,
3rd expansion link one end is passed through to rotate on middle arm before pair 13 is connected to, and the 3rd expansion link other end passes through to rotate pair
14 are connected on rear forearm, and the 4th expansion link one end is passed through rotation secondary 15 and is connected on bracing frame, before bracing frame is fixed on
On middle arm, the 4th expansion link other end passes through rotation secondary 16 and is connected on sliding sleeve, and sliding sleeve is sleeved on the 3rd expansion link,
First expansion link one end is passed through rotation secondary 17 and is connected on front forearm, and it is secondary that the first expansion link other end passes through rotation
18 are connected with scraper bowl pull bar one end, and the scraper bowl pull bar other end passes through rotation secondary 19 and is connected on scraper bowl, scraper bowl pole one end
It is connected on front forearm by rotating secondary 20, the scraper bowl pole other end is drawn with the first expansion link and scraper bowl by rotating secondary 18
Bar is simultaneously connected with.
Compared with prior art, the beneficial effect that the present invention possesses：
The forearm of the present invention is made up of rear forearm and front forearm, and the two passes through to rotate secondary five connections, and rotary motion pair five can
To change the direction of scraper bowl, crowd shovel is become by backhoe；Middle arm is made up of rear middle arm and front middle arm, and the two passes through to rotate secondary rotation pair
Three connections, the side of forearm movement to large arm can be excavated by rotary motion pair three.First expansion link is used for adjusting forearm
Angle and middle arm between, when forearm and middle arm form straight line, the dead-centre position that is, forearm and middle arm are in, can be utilized the
Two expansion links apply thrust to the first expansion link and forearm are rotated to the top of middle arm, or applying pulling force is during forearm returns
The lower section of arm.The present invention easily realizes required action when loading, and controls simple, maintenance is convenient, energy saving, rigidity
Height, bearing capacity are strong, error accumulation is little, and movement inertia is little, and dynamic performance is good.
