The utility model discloses a mechanical widen type screed hydraulic widening device of spreader machine, which comprises a guide rail fixing component arranged at two ends of the mechanical widen type screed of spreader machine. A movable width reduction plate component is arranged in the guide rail fixing component. A cylinder head end of a hydraulic telescopic cylinder is fixedly connected with the guide rail fixing component, and the piston rod end is fixedly connected with the width reduction plate. The utility model has simple structure, easy operation and reliable performance. The device makes the deficiencies of the mechanical widen type screed can not stepless change the spreading width, and can achieve the stepless change of the spreading width, which makes the spreading machine not only has the rigidity of the large width spreading operation but also has the conveniences of telescopic screed, improves the working efficiency of the spreading machine. Meanwhile the utility mode guarantees the operational quality of the large spreading width and effectively solves the difficulty of the spreading operation in the tunnel of the high-grade highway.
