Storage device for concrete powder

The invention relates to the technical field of concrete powder storage, and discloses a concrete powder storage device which comprises a storage tank used for storing concrete powder, the center of the top of the storage tank is rotationally connected with a driving pipe in a sealed mode through a rotating assembly, and the two ends of the driving pipe penetrate through the rotating assembly and extend outwards. The driving pipe and the outer tank top of the storage tank are jointly connected with a driving assembly used for driving the driving pipe to rotate, a stirring mechanism used for stirring concrete powder is further installed on the driving pipe, two material blocking assemblies are symmetrically connected to the outer tank wall of the storage tank, and each material blocking assembly comprises two supporting plates. The two supporting plates are symmetrically connected to the outer pipe wall of the storage tank, and a pressing plate is rotationally connected between the two supporting plates throug
