Abstract

The invention relates to an excavating mechanism of controllable three degree of freedom, comprising an excavating arm, a bucket turning-over mechanism, a backhoe bucket and a stand. The excavating arm is a mechanism of controllable planar two degree of freedom, wherein one end of a driving rod (1) of the mechanism is hinged together with a driven rod (2) through a hinge hole (9), and the other end is hinged on the stand (26) through a hinge hole (8); one end of a driving rod (4) is hinged together with a transmitting rod (3) through a hinge hole (12), and the other end is hinged on the hingehole (11) of the stand (26); and the driven rod (2) is a curved rod which is provided with a hinge hole (10) on the middle curved part and is hinged together with the transmitting rod (3). The invention solves the problems that the traditional mechanical excavating mechanism of single degree of freedom acts simply and the hydraulic excavating mechanism is easy to leak oil.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a planar three-degree-of-freedom controllable excavating mechanism. Background technique [0002] Excavator is an important construction machinery, which is widely used in mechanized construction such as industry, transportation, energy, farmland transformation, water conservancy, civil construction, mining and modern military engineering. So far, there are mainly two types of excavators: mechanical and hydraulic. Mechanical excavators have a history of more than 100 years. They use mechanical transmission parts to realize excavation actions, and they have the advantages of being strong and durable. However, the traditional single-degree-of-freedom mechanical excavator cannot complete complex actions. Even if it is only used for mining, it often encounters difficulties, such as: the bucket teeth cannot generate greater cutting force when digging a higher table; Basically, t...
