Method for realizing real-time metering of water-stable mixed materials

The invention relates to a method for realizing real-time metering of water-stable mixed materials. A pneumatic control unit, a metering mechanism and a belt conveyor connected with the metering mechanism are included. The method comprises the following steps that S1, the materials are conveyed into a transition bin of the metering mechanism to be screened; S2, the pneumatic control unit sends out a feeding instruction, the materials with different particle sizes are fed into a metering hopper at the bottom of the transition bin, and meanwhile weighing and sampling are carried out on the metering hopper; S3, when the materials in the metering hopper reach the upper limit, the pneumatic control unit closes a discharging door and detects the total weight of the metering hopper and the materials; and S4, when the total weight of the metering hopper and the materials reaches a preset value, the discharging door at the bottom of the metering hopper is opened, the materials are fed into the belt conveyor, and meter
