Description
Technical field
The present invention relates to mechanical field, the connecting rod controllable type digging mechanism of a kind of Multi-angle working.
Background technology
Excavator, also known as excavation machinery, is to excavate higher or lower than the material holding machine side with scraper bowl, and loads haulage vehicle
Or unload the earthmoving machinery to 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.Excavator common on market is all to use large arm, swing arm and the mechanism of scraper bowl series connection,
Oil cylinder is integrated on each arm, and such design makes swing arm simultaneously work as the effect that force is excavated and carried scraper bowl weight,
High to the oil cylinder performance requirement driving swing arm, have impact on the lifting of Bucket capacity and Operating Weight.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that the connecting rod controllable type digging mechanism of a kind of Multi-angle working.
To achieve these goals, present invention employs techniques below scheme:
A kind of connecting rod controllable type digging mechanism of Multi-angle working, including first connecting rod, second connecting rod, third connecting rod,
Double leval jib, the first expansion link, the second expansion link, the 3rd expansion link, the 4th expansion link, the first slide block, the second slide block, scraper bowl and machine
Frame,
First connecting rod one end is connected in frame by revolute pair one, and the first connecting rod other end passes through revolute pair two and second
Connecting rod one end connects, and the second connecting rod other end is connected on scraper bowl by revolute pair three,
Third connecting rod one end is connected in frame by revolute pair four, and the third connecting rod other end passes through revolute pair five and the 4th
Connecting rod one end connects, and the fourth link other end is connected on scraper bowl by revolute pair six,
First expansion link one end is connected in frame by revolute pair seven, and the other end is connected to first even by revolute pair eight
On bar,
Second expansion link one end is connected in frame by revolute pair nine, and the other end is connected to the 3rd even by revolute pair ten
On bar,
3rd expansion link one end is connected in frame by revolute pair 11, and the other end is connected to the by revolute pair 12
On one slide block, the first slide block set is contained on second connecting rod,
4th expansion link one end is connected on second connecting rod by revolute pair 13, and the other end is connected by revolute pair 14
On the second slide block, the second slide block set is contained in fourth link.
Compared with prior art, the beneficial effect that the present invention possesses:
Have without cumulative error, precision compared with high, compact conformation, bearing capacity is big, rigidity is high and end effector inertia is little
Etc. feature, motion parts is lightweight, and speed is high, and dynamic response is good, and mechanism's output trajectory is flexible, work space big, work efficiency
Height, can solve tradition single-degree-of-freedom mechanical digging machine and can not realize the problems such as compound action, and complete machine structure is the compactest, zero
It is low that part manufactures processing request, can quickly excavate in bad environments, the construction site of narrow space and needing, removes obstacles, smooth
Burst accident rescue site can play preferably effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the connecting rod controllable type digging mechanism of a kind of Multi-angle working of the present invention.
Detailed description of the invention
Below by embodiment, technical scheme is further elaborated.
