Description
Technical field
The present invention relates to mechanical field, specifically a kind of multi link high accuracy carries greatly excavator.
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 a kind of multi link high accuracy carries greatly excavator.
To achieve these goals, present invention employs techniques below scheme:
Multi link high accuracy carry greatly excavator, including first connecting rod, second connecting rod, third connecting rod, fourth link, first
Expansion link, the second expansion link, the 3rd expansion link, the 5th connecting rod, six-bar linkage, the 4th expansion link, the first 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 by revolute pair 12 and the 5th
Bar one end connects, and the 5th connecting rod other end is connected with six-bar linkage one end by revolute pair 13, and the six-bar linkage other end passes through
Revolute pair 14 is connected in fourth link, is connected on third connecting rod by revolute pair 15 in the middle part of the 5th connecting rod,
4th expansion link one end is connected on second connecting rod by revolute pair 16, and the other end is connected by revolute pair 17
On the first slide block, the first slide block set is contained on second connecting rod.
Compared with prior art, the beneficial effect that the present invention possesses:
Present invention reduces the bearing load of each rod member, reduce the rotary inertia of complete machine, stable drive, without sideshake, essence
Degree height, rigidity is high and has good dynamic performance, each connecting rod and expansion link reasonable Arrangement, improves the balance of integrated model
Can, further increase the dynamic performance of mechanism.
