Multidirectional building mixer

The utility model relates to a multidirectional building mixer, which belongs to the technical field of a mixer, and is mainly used for mixing concrete and various mortar on a construction site. A main shaft of the mixer is set as a hollow pipeline, a belt is arranged inside the hollow pipeline, two ends of the belt are respectively connected with a transverse shaft and an auxiliary shaft, the main shaft and the auxiliary shaft are respectively connected with a main motor and an auxiliary motor, a connecting hole with a connector is respectively formed on the junction of the main shaft and the transverse shaft and the junction of the main shaft and the auxiliary shaft, each connector is fixed on the inner wall of the main shaft, a bearing is arranged inside the connector, the transverse shaft and the auxiliary shaft penetrate through the connector, and two ends of the transverse shaft are provided with four ellipsoid stirring paddles. The multidirectional building mixer is reasonable in design, convenient to use and capable of stirring the to-be-mixed material in multiple directions, so that the stirring efficiency of the mixer can be greatly improved; in addition, the contact area of the stirring paddle and the to-be-mixed material is increased through the ellipsoid paddle blades, the resistance of the paddle blades in the rotation process can be reduced, and the power consumption of the motor can be reduced.
