Multi-connecting-rod controllable excavator
The invention discloses a multi-connecting-rod controllable excavator which comprises a walking device, a rotary platform, a first control branched chain, a second control branched chain, a big arm and a bucket. The rotary platform is arranged on the walking device. The first control branched chain comprises a first driving piece with one end hinged to the rotary platform, a first connecting rod with one end hinged to the other end of the first driving piece, and a first bucket rod with one end hinged to the other end of the first connecting rod. The second control branched chain comprises a second driving piece with one end hinged to the rotary platform, a second connecting rod with one end hinged to the other end of the second driving piece, a turning rod with one end hinged to the other end of the second connecting rod, and a second bucket rod with one end hinged to the other end of the turning rod. One end of the big arm is hinged to the rotary platform. The middle of the big arm is hinged to the bent part of the turning rod. The other end of the big arm is hinged to the bent part of the first bucket rod. The upper portion of the bucket is hinged to the other end of the first bucket rod. The lower portion of the bucket is hinged to the other end of the second bucket rod. The excavator can overcome the defects that an excavator with a hydraulic element is high in requirement for accuracy and prone to oil leakage.
