Multi-degree-of-freedom controllable excavation mechanism
The invention discloses a multi-degree-of-freedom controllable excavation mechanism, which comprises a rack, a swinging mechanism, a lifting and lowering mechanism and a bucket, wherein the swinging mechanism comprises a first active bar, a fourth connecting bar, a big arm, a first connecting bar and an overturn bar; one end of the first active bar and one end of the fourth connecting bar are independently hinged to the rack; one end of the big arm is hinged to the other end of the first active bar; one end of the first connecting bar is hinged to the other end of the big arm; one end of the overturn bar is hinged to the other end of the first connecting bar; the other end of the fourth connecting bar is hinged to the middle of the first connecting bar; the lifting and lowering mechanism comprises a second active bar, a second connecting bar and a third connecting bar, wherein one end of the second active bar is hinged to the rack, one end of the second connecting bar is hinged to the other end of the second active bar, and one end of the third connecting bar is hinged to the other end of the second connecting bar; the upper part of the bucket is hinged to the other end of the overturn bar; the lower part of the bucket is hinged to the other end of the third connecting bar. The excavation mechanism has the flexibility of a traditional hydraulic excavator on the premise that the operation requirement of the traditional excavator and the simple structure of a connecting bar mechanism are guaranteed, and the defects of low precision, oil leakage and the like of a hydraulic element are avoided.
