Description
Technical field
The present invention relates to machinery field, specifically a kind of convertible Multipurpose dredger of crowd shovel backhoe.
Background technique
Excavator, also known as excavating machinery are to be excavated to be higher or lower than the material for holding machine side with scraper bowl, and be packed into haulage vehicle
Or it unloads 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 engineering construction
In one of most important engineering machinery.Divide according to scraper bowl, excavator can be divided into forward shovel, backacter, drawing again
Shovel excavator and clam shell excavator.Forward shovel is chiefly used in excavating the material of earth's surface or more, and backacter is chiefly used in excavating
Earth's surface material below.It is most common that backacter backhoe type is that we met, and backward downwards, soil is cut in pressure, can be used for
Shut down work surface excavation below, elemental operation mode has: ditch end is excavated, ditch side is excavated, straight line excavates, curve excavates, is kept
Certain angle excavation, super deep trench excavation and the excavation of ditch slope etc..The shovel soil action form of forward shovel, its main feature is that " advance to
On, soil is cut in pressure ".Crowd shovel digging force is big, can excavate the soil in shutdown face or more, is preferably used for the drying base that excavation height is greater than 2m
Hole, but must setting up and down ramp.The bucket of crowd shovel is larger than the bucket of the excavator of the backhoe of same equivalent, can excavate water content
One no more than 27% is native to three classes, and completes entire excavation hauling operation with dump truck cooperation, and it is dry can also to excavate large size
Dry foundation pit and mound etc..The digging mode of face shovel is dug according to the difference for the relative position for excavating route and haulage vehicle
Soil and the mode for unloading soil have following two: forward direction is cut the earth, and soil is laterally unloaded；Forward direction is cut the earth, and soil is reversely unloaded.
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 when machine, a backacter must be looked for when construction site needs backacter, when need
When being used alternatingly, it is necessary to which two different excavators are constructed, this is because the unicity of excavator function makes
Construction cost increases, and the service efficiency of separate unit excavator is lower, and the rotation of big arm of digger, forearm and scraper bowl at present is all
In the same plane, front can only be excavated, spatial degrees of freedom is lower.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of convertible Multipurpose dredgers of crowd shovel backhoe.
To achieve the goals above, the invention adopts the following technical scheme:
A kind of convertible Multipurpose dredger of crowd shovel backhoe, including pedestal, large arm, it is rear in arm, preceding middle arm, rear forearm,

It connects, the rear middle arm other end is connect by revolute pair three with preceding middle arm one end, and the preceding middle arm other end passes through revolute pair four and rear forearm
One end connection, the rear forearm other end are connect by revolute pair five with preceding forearm one end, and the preceding forearm other end is connected by revolute pair six
Connect on scraper bowl, the Plane of rotation of revolute pair three is vertical with the Plane of rotation of revolute pair two, the Plane of rotation of revolute pair five with turn
The Plane of rotation of dynamic pair four is vertical,
The pedestal is equipped with the groove of vertical direction, and bottom portion of groove is equipped with jack, and support stake is installed in a groove
On jack, big arm hydraulic cylinder one end is connected in support stake by revolute pair seven, and the big arm hydraulic cylinder other end passes through revolute pair
Eight are connected in large arm,
First telescopic rod one end is connected in large arm by revolute pair nine, and the first telescopic rod other end is connected by revolute pair ten
It connects on rear middle arm, second telescopic rod one end is connected on the first support frame by revolute pair 11, and the first support frame is fixed on
In large arm, the second telescopic rod other end is connected on the first sliding sleeve by revolute pair 12, and it is flexible that the first sliding sleeve is sleeved on first
On bar,
Before being connected to by revolute pair 13 on middle arm, the third telescopic rod other end passes through revolute pair for third telescopic rod one end
14 are connected on rear forearm, and the 4th telescopic rod one end is connected on the second support frame by revolute pair 15, the second support frame
In before being fixed on arm, the 4th telescopic rod other end is connected on the second sliding sleeve by revolute pair 16, and the second sliding sleeve is sleeved on
On third telescopic rod,
Before 5th telescopic rod one end is connected to by revolute pair 17 on forearm, the 5th telescopic rod other end passes through revolute pair
18 connect with scraper bowl pull rod one end, and the scraper bowl pull rod other end is connected on scraper bowl by revolute pair 19, scraper bowl strut one end
Before being connected to by revolute pair 20 on forearm, the scraper bowl strut other end is drawn by revolute pair 18 and the 5th telescopic rod and scraper bowl
Bar connects simultaneously.
Compared with prior art, the present invention have the utility model has the advantages that
Forearm of the invention is made of rear forearm and preceding forearm, and the two is connected by revolute pair five, and rotary motion pair five can
To change the direction of scraper bowl, crowd shovel is become by backhoe；Middle arm is made of rear middle arm and preceding middle arm, and the two passes through revolute pair revolute pair
Three connections, the side that forearm can be moved to large arm by rotary motion pair three is excavated.First telescopic rod is for adjusting forearm
The angle between middle arm, when forearm and middle arm form straight line, i.e. the dead-centre position that is in of forearm and middle arm, using the
Two telescopic rods apply thrust to the first telescopic rod and forearm are rotated to the top of middle arm, or applying pulling force is during forearm returns
The lower section of arm.Required movement when loading easy to accomplish of the invention, control is simple, and maintenance is convenient, energy saving, rigidity
Height, bearing capacity is strong, error accumulation is small, and movement inertia is small, and dynamic performance is good.
