Concrete stirring device for constructional engineering

The utility model relates to the technical field of building construction, in particular to a concrete stirring device for constructional engineering, which comprises a stirring barrel, a rotating column and a second motor, the upper end of the stirring barrel is provided with a first motor, a support plate and a rotating shaft, the upper end of the rotating column is provided with a worm wheel disc and a special-shaped cylinder, and one side of the second motor is provided with a driving gear and a driven gear; the device has the beneficial effects that a first motor is started to drive a stirring rod to rotate through a rotating shaft, then a second motor is started to drive a driving gear to rotate, a rotating column drives a special-shaped cylinder to rotate under the action of a driven gear, a worm and a worm wheel disc, and therefore a supporting plate is driven to move up and down on the outer wall of a guide rod under the limiting action of an arc-shaped plate; the telescopic spring is stretched, so t
