12R controllable excavating mechanism with actively and alternatively metamorphic big arm
The invention discloses a 12R controllable excavating mechanism with an actively and alternatively metamorphic big arm. The 12R controllable excavating mechanism comprises a frame, a big arm swinging mechanism, a bucket rod elevating mechanism, a bucket turnover mechanism and electromagnetic locking devices, wherein the big arm swinging mechanism comprises a big arm and a swinging mechanism; the bucket rod elevating mechanism comprises a bucket rod and an elevating mechanism; the bucket turnover mechanism comprises a bucket and a turnover mechanism; the electromagnetic locking devices are arranged on revolute pairs; an active metamorphism function is realized through electromagnetic locking of the revolute pairs. According to the 12R controllable excavating mechanism, a connecting rod transmission mechanism is adopted instead of the conventional hydraulic transmission, so that the defects of complexity in a hydraulic system, easiness in oil leakage and the like in a hydraulic excavator are overcome; the electromagnetic locking devices are arranged on the revolute pairs, so that active metamorphism can be realized according to different operation conditions, the flexibility of the hydraulic excavator is realized, three-degree-of-freedom excavating operation can be realized by using two driving levers, and the manufacturing cost of the excavating mechanism is lowered; the 12R controllable excavating mechanism is suitable for manufacturing various excavators and other engineering machinery.
