Concrete stirring device

The invention belongs to a concrete stirring device which comprises a stirring box. A motor is installed on the upper end face of the stirring box, the output end of the motor penetrates through the upper end face of the stirring box and extends into the stirring box, and the output end of the motor is fixedly connected with a rotating shaft. Rotating spray heads are started, and the rotating spray heads conduct rotating spray cleaning on the interior of the stirring box, and the cleaning effect is good. Second air cylinders shrink to drive movable blocks to rotate by taking shaft pins as the center, so that the rotating spray heads at the bottoms of the movable blocks are subjected to angle adjustment, the interior of the stirring box is fully sprayed and cleaned, the situations that concrete remains in the stirring box and concrete caking occurs are avoided, and the problems that the interior of an existing concrete stirring device is very inconvenient to clean, the cleaning effect is poor, residual concret
