Concrete powder storage hopper

The utility model discloses a concrete powder storage hopper has solved prior art, and the speed that the control discharge gate was opened and was closed is too slow, harder controls the problem of the volume of the ejection of compact at ejection of compact in -process, and its technical scheme main points are, a concrete powder storage hopper, be the storage bucket body and the discharge gate of setting in storage bucket body lower extreme portion that cylindrical lower part is big -end -up's round platform shape including top, discharge gate department is provided with the fixed disk and is the annular rolling disc of being connected with the fixed disk rotation, the fixed disk internal slipping is provided with at least two and can slides to the limiting plate of discharge gate, thereby the limiting plate passes through the rotation of rolling disc relatively fixed dish to be slided towards the discharge gate is central by the drive, seal the discharge gate when limiting plate contacts in the discharge g
