Abstract

The invention discloses a simple mechanical loading mechanism with a forward turnover function and two degrees of freedom. The simple mechanical loading mechanism comprises a framework, a movable arm control branched chain and a bucket control branched chain. The movable arm control branched chain is controlled by a first driving rod and carries out movable arm lifting or dropping operation, the bucket control branched chains is controlled by a second driving rod and turns a bucket over, and loading and unloading operation of the mechanical loading mechanism is functionally completed under mutual cooperation of the movable arm lifting branched chain and the bucket control branched chain. The simple mechanical loading mechanism has the advantages that various rod pieces of the mechanical loading mechanism are connected with one another by rotation pairs, and accordingly shortcomings of high manufacturing cost, poor reliability, high maintenance cost and the like of the traditional full-hydraulic loading mechanism with moving pairs can be overcome; the mechanical loading mechanism is compact in structure and high in rigidity as compared with other controllable mechanical loading mechanisms, is of a novel structure with excellent kinematics and dynamics performance and accordingly is good in reliability and dynamic stability.
