Concrete supply device for constructional engineering

The utility model relates to the technical field of constructional engineering, and discloses a concrete supply device for constructional engineering, which comprises a supply box, two sides of the top of the supply box are communicated with feeding pipes, two sides of the top end in the supply box are bolted with guide hoppers, and the guide hoppers correspond to the feeding pipes. A motor is in bolted connection with the axis of the top of the supply box, the output end of the motor penetrates through a hole in the top of the supply box and is connected with a rotating shaft, the surface of the rotating shaft is fixedly sleeved with a dispersing disc, the dispersing disc is located at the bottom of the guide hopper, and a mixing screw is in bolted connection with the bottom end of the rotating shaft. According to the concrete mixing device, raw materials are scattered to each place in the device by utilizing centrifugal force in the feeding process, so that the scattering step is reduced, and concrete mixin
