Function is dug, since the walking type excavator of the utility model is not provided with gyroscopic drive system, after bucket 1 excavates the cubic metre of earth and stone, is led to
Crossing swing arm steering hydraulic device 212 drives sliding seat 35 to swing in the horizontal plane, to drive connection arm assembly 2 in level
It swings in face, so that the cubic metre of earth and stone of excavation to be placed on to the two sides of digging operation position.
Then, walking type excavator need to advance operation when, as shown in figure 3, by swing arm 21, dipper 22, connecting rod 12 with
And the mutual cooperation effect of bucket 1, so that the arc part of bucket 1 is contacted ground, so that bucket 1 be made to form whole one of excavator
A supporting point, dipper hydraulic device 221 push the first end of dipper 22, so that grip supporting leg 33 leaves ground, excavator is whole
It is the link mechanism of supporting point that body, which forms one with traveling wheel 31 and bucket 1, at this point, dipper hydraulic device 221 pushes dipper 22
First end, dipper 22 with bucket 1 be rotation center rotate and moved forward under the action of traveling wheel 31 with motor vehicles bodies 3,
The walking type excavator of the utility model is without providing the driving force for moving forward excavator integrally.In addition, such as needing car body 3
It moves backward, dipper hydraulic device 221 pulls the first end of dipper 22 can be realized after shrinking.
Finally, bucket hydraulic device 11 retracts, bucket 1 is lifted up, and grip supporting leg 33 moves down, and grip supporting leg 33
Second end support on the ground, excavator is whole can be fixedly supported on the ground again by grip supporting leg 33 and traveling wheel,
To continue digging operation.
Referring to the schematic diagram that Fig. 5, Fig. 5 are when walking type excavator rotates.The walking type excavator of the utility model turns
Transportation method includes the following steps.
Support rod 34 is fixed on firstly, the first fixing piece sequentially passes through the fixation hole on fixed part 341 and fixed part 37
On car body 3, and extend in vertical direction support rod 34, the support of walking auxiliary wheel 32 is on the ground.
Then, grip supporting leg hydraulic device 331 drives grip supporting leg 33 to rotate, and the second end of grip supporting leg 33 is made to leave ground
Face.
Finally, walking type excavator moves forward and enters transport vehicle.
In addition, car body can also include the rotary table and revolving platform that are hinged, the second end of connection arm assembly with
Revolving platform is hinged, and traveling wheel, walking auxiliary wheel and grip supporting leg are mounted on rotary table, big by setting revolving platform
The big job area for increasing walking type excavator.In addition, when walking type excavator is transported through, it can also be by grip supporting leg and row
It walks auxiliary wheel to pack up, so that directly haul excavator is whole.Above scheme is also able to achieve the purpose of this utility model.
Therefore made by setting grip supporting leg and setting by support rod and the hinged walking auxiliary wheel of car body
Obtaining walking type excavator can support progress operation, in transhipment, can pass through walking auxiliary in operation by grip supporting leg
Wheel is moved.The walking type excavator of the utility model, structure is simple, and economic performance is higher, and adapts to complicated landform,
It especially adapts in operation in narrow space and operations specific, such as ditching canal.In addition walking type excavator transhipment is convenient, nothing
Specific loading vehicles are needed, can both get on the bus transport with complete machine, can also haul using trailer.In addition, walking type excavator does not have
Travel driving system and rotary system, power consumption is each hydraulic device, therefore required power is smaller, energy conservation and environmental protection.
