Hydraulic control device of blending stacker

The utility model relates to the technical field of stacking devices. The utility model further discloses a hydraulic control device of the blending stacker. The device comprises a sliding rail, a rotating base is movably installed at the top of the sliding rail, a first hydraulic rod is movably hinged to the top of the rotating base, a middle connecting base is movably hinged to the top of the first hydraulic rod, a middle base is fixedly installed at the top of the rotating base, and a second hydraulic rod is movably installed on the right side face of the middle base. The utility model discloses a hydraulic control device of a blending stacker. Through cooperation of a first hydraulic rod, a second hydraulic rod and a middle connecting base, the inclination direction of a third hydraulic rod can be changed, and then the pitching range of the first framework mechanism can be greatly adjusted through the third hydraulic rod; the inclination angle of the second framework mechanism relative to the first framew
