Flying dust prevention packaging device for concrete admixture production

The utility model discloses a dust raising prevention packing device for concrete admixture production, which comprises a device frame, a dust collecting cover, a metering cylinder and a collecting box, the dust collecting cover is fixed at one end of the bottom of the device frame, fixing rods are symmetrically connected to two sides in the dust collecting cover, and the metering cylinder is fixed in the dust collecting cover through the fixing rods. Under the action of the conveying auger, raw materials in the storage hopper are conveyed into the metering cylinder through the discharging port, the pressure sensor weighs the raw materials in the metering cylinder all the time, and when the mass of the raw materials in the metering cylinder reaches a set value, the controller controls the conveying auger to stop conveying the raw materials, so that the raw materials are weighed, and the metering cylinder is started. And after the raw materials in the metering cylinder are discharged, the controller controls t
