Concrete mixing mechanism

The utility model provides a concrete mixing mechanism, which relates to the technical field of concrete processing and comprises a mixing tank, and a motor is arranged on the outer surface of the mixing tank through an auxiliary plate. When the stirring device is used, the motor is started to enable the output shaft of the motor to rotate, so that the driving gear is driven to rotate, the driving gear is in contact with the rotating disc to drive the rotating disc to rotate, and the rotating disc is connected with the stirring assembly and rotates in the stirring tank at the same time; during rotation, concrete attached to the inner wall and the bottom surface of the stirring tank can be scraped down, so that the stirred concrete can be fully utilized, at the moment, the rotating rod can drive the stirring blades to rotate, and the concrete stirring effect is achieved; the problems that concrete remains on the inner wall and the bottom of the stirring hopper when the concrete is stirred in the stirring hoppe
