Modified asphalt mixture dry method direct addition additive batching device

Abstract

The utility model relates to the technical field of modified asphalt additive production equipment, and particularly discloses a modified asphalt mixture dry-process direct-feeding additive batching device which comprises a plurality of batching barrels, the batching barrels are fixed at the top of a support, the bottom of each batching barrel is communicated with an auger conveyor, and the auger conveyor is communicated with a feed hopper. A batching counterweight mechanism is arranged at the bottom of the conveying pipe and comprises a high-precision weighing device, the high-precision weighing device comprises a high-precision weight sensor, and an electric push rod device is arranged below the high-precision weighing device. According to the technical scheme, the trigger value of the high-precision weighing device below each batching barrel is correspondingly set according to the required weight of each raw material, each group of auger conveyors are started at the same time, and when the trigger values of the high-precision weighing devices are reached, the industrial personal computer automatically controls the corresponding auger conveyors to stop running; the raw materials of the modified asphalt additive are quickly and uniformly conveyed into the material collecting barrel to complete quick batching, and the device has the advantages of being easy to operate and quick in batching.
