Hydraulic mixer

The utility model relates to a hydraulic mixer which comprises a flat car and a cantilever support, a lifting frame is installed on the upper surface of the front portion of the flat car, one end of the cantilever support is fixedly connected with a telescopic end at the top of the lifting frame, and the other end of the cantilever support horizontally extends outwards in the direction away from the lifting frame and extends to the outer side of the flat car to be in a suspended state. A hydraulic motor mounting seat is mounted at the suspended end of the cantilever support, a hydraulic motoris mounted on the hydraulic motor mounting seat, and a vertically-arranged stirring and mixing mechanism is mounted on a power output shaft of the hydraulic motor. The slurry spraying machine has theadvantages of being strong in maneuverability, easy to move, high in moving speed, easy to repair and maintain, free of manual hoisting and carrying, and capable of shortening the distance between a stirring place and a workin
