The utility model provides a concrete pile expanding bottom stirring device, the utility model aims to solve the existing telescopic stirring head is controlled by the hydraulic device, if encountered in the construction of complex geological conditions, sometimes the hydraulic rod distorted, sometimes to the hydraulic tubing broken, causing the construction pause moreover, maintenance more trouble, seriously affect the duration of the problem. The utility model has the technical scheme: drill pipe, spiral blade, shaft, steel wire rope, the stirring head supporting plate and the stirring head, the spiral vane is fixed on the drill pipe, the stirring head supporting plate is fixed on the drill pipe on the outer wall of the stirring shaft hole on the head of the shaft and the stirring head supporting plate is hinged at the lower end of the connecting wire rope. In the mixing head within the rope hole. The utility model has the advantages of simple structure, easy construction under complicated geological conditions, and simple operation. Even if the rope is broken, the repair is also very quick and will not be delayed due to repair.
