Description
Technical field
The present invention relates to mechanical field, specifically a kind of connecting-rod mechanism type excavator.
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.On market, common excavator is all the mechanism using the series connection of large arm, swing arm and scraper bowl,
Oil cylinder is integrated on each arm, and such design makes swing arm simultaneously work as the effect excavated and carry scraper bowl weight that exerts a force,
High to the oil cylinder performance requirement driving swing arm, have impact on the lifting of Bucket capacity and Operating Weight.
Content of the invention
The present invention is directed to the deficiencies in the prior art, provides a kind of connecting-rod mechanism type excavator.
To achieve these goals, present invention employs technical scheme below：
A kind of connecting-rod mechanism type excavator, including first connecting rod, second connecting rod, third connecting rod, fourth link, first stretch
Bar, the second expansion link, the 3rd expansion link, the 4th expansion link, the first slide block, scraper bowl and frame,
First connecting rod one end is passed through rotation secondary and is connected in frame, and the first connecting rod other end passes through to rotate secondary two and second
Connecting rod one end connects, and the second connecting rod other end passes through rotation secondary three and is connected on scraper bowl,
Third connecting rod one end is passed through rotation secondary four and is connected in frame, and the third connecting rod other end passes through to rotate secondary five and the 4th
Connecting rod one end connects, and the fourth link other end passes through rotation secondary six and is connected on scraper bowl,
First expansion link one end is passed through rotation secondary seven and is connected in frame, and the other end is connected to first by rotation secondary eight and connects
On bar,
Second expansion link one end is passed through rotation secondary nine and is connected in frame, and the other end is connected to the 3rd by rotation secondary ten and connects
On bar,
4th expansion link one end is passed through to rotate secondary 13 and is connected in frame, and the other end passes through to rotate secondary 14 and is connected to the
On one slide block, the first slide block is sleeved in fourth link, and the 3rd expansion link one end is passed through rotation secondary 11 and is connected to the first slide block
On, the other end passes through rotation secondary 12 and is connected on second connecting rod.
Compared with prior art, the beneficial effect that the present invention possesses：
Compared with high, compact conformation, large carrying capacity, rigidity height and end effector inertia is little to have no cumulative error, precision
The features such as, motion parts are lightweight, and speed is high, and dynamic response is good, and mechanism's output trajectory is flexible, work space big, work efficiency
Height, the problems such as solving traditional single-degree-of-freedom mechanical digging machine and do not enable compound action, complete machine structure is simply compact, zero
It is low that part manufactures processing request, can quickly excavate in bad environments, the construction site of narrow space and needing, remove obstacles, smooth
Burst accident rescue site can play preferable effect.
Brief description
Fig. 1 is a kind of structural representation of connecting-rod mechanism type excavator of the present invention.
Specific embodiment
Below by embodiment, technical scheme is further elaborated.
