Concrete aggregate batching bin based on pneumatic device

The invention relates to the technical field of concrete material processing equipment, in particular to a concrete aggregate batching bin based on a pneumatic device, which is characterized in that aggregate is poured into a storage device to be stored, then when the aggregate is used, the storage device discharges the aggregate into a weighing device, an air pump is turned on, and the weighing device is turned on; air is discharged into odd air pipes and even air pipes of the air pipes through cooperation of a reversing valve, a first guide pipe and a second guide pipe, the fluctuation effect is achieved through circulating exhaust, aggregate at the corners in the material storage device is shaken off, and then the aggregate discharged from the material storage device is weighed through a weighing device; then the weighing device discharges the weighed aggregate, so that the material blocking phenomenon is reduced, and the practicability of the equipment is improved; comprising a storage device, a weighing
