Concrete stirring machine

The invention discloses a concrete stirring machine. The concrete stirring machine comprises a shell, supporting legs and a stirring mechanism. The supporting legs are uniformly arranged at the bottomof the shell. A feeding port is formed in the upper portion of the shell. The stirring mechanism comprises a driving part, a stirring shaft and a blade assembly. The stirring shaft is transversely rotationally arranged in the shell. One end of the stirring shaft penetrates out of the shell and is rotationally connected with the driving part. The blade assembly is composed of a plurality of stirring blades uniformly distributed on the stirring shaft. Each stirring blade comprises an inner blade body connected with the stirring shaft and an outer blade body connected with the corresponding inner blade body. The inner blade bodies form spiral conveying, and opposite spiral conveying is formed between the outer blade bodies and the inner blade bodies. By the adoption of the concrete stirringmachine, sufficient stirri
