FIELD: agriculture.
SUBSTANCE: invention relates to a hinge mechanism for the working machine for building-block design of the working apparatus with the working machine. The hinge mechanism comprises a lifting shaft unit mounted on the bearing frame of the working machine and a connecting system kinematically connected to it. The lifting shaft unit comprises a lifting shaft at least one lifting arm rigidly connected to the lifting shaft, and at least one lifting cylinder pivotally connected to the lifting arm. The connecting system comprises first upper connecting links pivotally mounted on the bearing frame, and the second lower connecting links pivotally mounted on the bearing frame and the connecting elements pivotally mounted on the lifting arms of the lifting shaft, and at least one of the connecting elements is made rigid.
EFFECT: in the mechanism at unsymmetrical loading appliance a uniform distribution of loading on the connecting links is provided.
