The invention discloses a concrete stirring device with a water cooling function. The concrete stirring device comprises a rack, a stirring tank and a motor. The stirring tank is cylindrical. One end of the stirring tank is provided with a feed inlet, and the other end of the stirring tank is provided with a discharge outlet. A feed device is arranged at the discharge outlet of the stirring tank and comprises a hopper and a second roller which is fixedly connected with the hopper and movably connected with the stirring tank. A port of the hopper is provided with a deduster. A third roller is arranged in the center of a closed door and connected with a spray head of an outer end water inlet device. The spray head is connected to a water tank through a water pump. A condenser is further arranged between the water pump and the water tank. The concrete stirring device has the beneficial effects that the concrete stirring device is provided with a water spraying device for spraying water towards the stirring tank during rotation of the stirring tank, and the stirring effect of materials is improved; and the sprayed water is cooled to a low temperature through the condenser to cool the stirring tank, and the motor is protected.
