The invention provides a hopper of a concrete spreader. The hopper of the concrete spreader comprises a hopper body and a discharging port in the bottom of the hopper, a flap lid covers an opening of the discharging port and rotatably connected with the hopper body through a rotating shaft, and springs are arranged between the flap lid and the side wall of the hopper body. When concrete spreading stops, the discharging port is covered by the flap lid under elasticity of the springs, and accordingly pollution of a construction environment due to scattering of residual slurry all the way is avoided, and slurry waste is avoided as well.
