Concrete stirring device

The invention discloses a concrete stirring device which comprises a shell, a power shaft, a stirring shaft, a driving extrusion wheel and a driven extrusion wheel. The power shaft is connected to one end of the shell through a bearing and a sealing ring. A motor is connected to one end of the power shaft, and the stirring shaft is connected with the other end of the power shaft. A set of support a and support b are connected to the stirring shaft symmetrically. The driving extrusion wheel is arranged on the support a, and the driven extrusion wheel is arranged on the support b. The driving extrusion wheel and the driven extrusion wheel are connected with an extrusion block a and an extrusion block b respectively. The extrusion block a and the extrusion block b are connected with a discharging plate arranged at the other end of the shell. The shell is further provided with a feed inlet. The concrete stirring device is simple in structure; the extrusion wheels are adopted for extrusion discharging, the extrusion intensity is high, and the middle of the extrusion block a and the middle of the extrusion block b are convex, so that material flowing is facilitated, the discharging speed is high, the discharging efficiency is effectively improved, the phenomenon that a device body gets stuck is reduced, and performance is stable.
