Abstract

The invention relates to a reverse turning bucket two-freedom degree mechanical loading mechanism. The reverse turning bucket two-freedom degree mechanical loading mechanism consists of a machine frame, a movable arm control branched chain and a bucket control branched chain, wherein the movable arm control branched chain is controlled by a first driving lever to elevate a movable arm; the bucket control branched chain is controlled by a second driving lever and is used for turning a bucket. The mechanical loading mechanism is operated to load and unload by the interaction of the movable arm elevating branched chain and the bucket control branched chain. According to the mechanical loading mechanism, all the levers are connected through revolute pairs, and thereby the defects of high cost, low reliability, high maintenance cost and the like of the conventional full hydraulic loading mechanism with sliding pairs are overcome. Moreover, compared with other controllable loading mechanisms, the mechanical loading mechanism has the advantages of compact structure, high rigidity, and novel structure with superior kinematic and dynamic performance, and thereby the mechanical loading mechanism is higher in reliability and dynamic stability.
