The invention discloses a cement wheelbarrow. The cement wheelbarrow comprises a hopper, wheelbarrow handles, wheelbarrow legs and wheelbarrow wheels. The wheelbarrow wheels are arranged at the lower end of the hopper. The wheelbarrow handles are arranged at the back end of the hopper. The wheelbarrow legs are vertically arranged on the wheelbarrow handles. The cement wheelbarrow is characterized in that the hopper is provided with brake stopping seats capable of being overturned, the front end surfaces of the brake stopping seats are arranged to be of arc shapes for being matched with wheelbarrow wheels, the back end surfaces of the brake stopping seats are of oblique tooth shapes, speed reducing strips are arranged above the wheelbarrow wheels, wherein the speed reducing strips can adjust the position of the speed reducing strips and the wheelbarrow wheels, the speed reducing strips are provided with hooking parts matched with the brake stopping seats in a tooth-shaped mode, when the cement wheelbarrow is parked or goes up a slope, the brake stopping seats are overturned until the bottom end surfaces of the brake stopping seats make contact with the ground, and the front end surfaces of the brake stopping seats are tightly attached to the back sides of the wheelbarrow wheels; and when the cement wheelbarrow goes down the slope, the brake stopping seats are overturned to be above the speed reducing strips, the hooking parts of the speed reducing strips hook the back end surfaces of the brake stopping seats, the brake stopping seats are overturned through a connecting rod assembly to achieve position switching, when the cement wheelbarrow is parked or goes up the slope, the wheelbarrow can be prevented from sliding backward, and when the cement wheelbarrow goes down the slope, the speed reducing strips press the wheelbarrow wheels to achieve speed reducing.
