Electromagnetic type initiative metamorphism (3R-4R)R-4R-4R closed-chain connecting rod controllable excavating mechanism
The invention discloses an electromagnetic type initiative metamorphism (3R-4R)R-4R-4R closed-chain connecting rod controllable excavating mechanism which comprises a rack, a large arm swinging mechanism, a bucket rod ascending and descending mechanism, a bucket overturn mechanism and an electromagnetic locking device. The large arm swinging mechanism comprises a large arm and a swinging mechanism body. The bucket rod ascending and descending mechanism comprises a bucket rod and an ascending and descending mechanism body. The bucket overturn mechanism comprises a bucket and an overturn mechanism body. The electromagnetic locking device is installed on a rotation pair, and the initiative metamorphic function is achieved through electromagnetic locking of the rotation pair. According to the electromagnetic type initiative metamorphism (3R-4R)R-4R-4R closed-chain connecting rod controllable excavating mechanism, a connection rod transmission mechanism is used for replacing traditional hydraulic transmission, the defects that a hydraulic system of a hydraulic excavator is complex and prone to oil leakage can be overcome, due to the fact that the electromagnetic locking device is adopted in the rotation pair, initiative metamorphism can be achieved according to different work conditions, the flexibility of the hydraulic excavator is achieved, three-degree-of-freedom excavation work can be achieved through two drive rods, the construction cost of the excavating mechanism is reduced, and the electromagnetic type initiative metamorphism (3R-4R)R-4R-4R closed-chain connecting rod controllable excavating mechanism is suitable for manufacturing various excavators and other engineering machines.
