Metering device 4 is used for weighing the additive to provide the additive of the required weight of production, metering device 4 is provided with additive and puts in the mouth, is used for putting in the additive to pitch agitating unit, in order to satisfy the ratio demand of pitch to the additive.

The lifting device 1, the guide pipe 5, the storage device 2, the conveying device 3 and the metering device 4 are all closed devices and are sequentially connected in a closed manner to form a set of closed system. In the production process, the additive sequentially passes through the lifting device 1, the guide pipe 5, the storage device 2, the conveying device 3 and the metering device 4 and is put into the asphalt stirring device, so that the putting operation of the asphalt additive putting system is realized. The controller is respectively electrically connected with the lifting mechanism, the level indicator 21, the conveying device 3 and the metering device 4 so as to correspondingly control the lifting mechanism 1, the conveying device 3 and the metering device 4 according to weighing information of the metering device 4. Specifically, when the weighing value of the metering device 4 is lower than the preset weight, the controller controls the pneumatic butterfly valve 34 to open, and simultaneously controls the driving motor 35 to operate, so as to drive the screw conveying mechanism 32 to rotate, and convey the additive entering the conveying pipe 31 from the storage device 2 to the metering device 4. When the weighing value of the metering device 4 reaches the preset weight, the amount of the additive in the metering device 4 reaches the proportioning requirement of the asphalt on the additive, and the additive can be put into the asphalt stirring device, at the moment, the controller controls the pneumatic butterfly valve 34 to close the second branch pipe 332, and controls the driving motor 35 to stop, so that the spiral conveying mechanism 32 stops conveying the additive, and the accurate putting operation of the asphalt additive putting system on the additive is realized. In addition, the controller can also control the lifting mechanism according to the material level of the additive in the storage device 2 detected by the material level meter 21, and when the material level of the additive in the storage device 2 reaches a preset material level, the lifting mechanism is controlled to stop supplying the additive into the storage device 2, so that the additive in the storage device 2 is prevented from exceeding the maximum carrying capacity of the storage device 2. Optionally, the preset level is 80% to 95% of the maximum level of the stock storage device 2. The preset weight is the weight of the additive according with the asphalt proportion in the asphalt stirring device.

Above combine the figure to explain in detail the utility model discloses a technical scheme can realize carrying out the accuracy to the required additive of pitch and put in, makes the process of putting in of additive be in airtight device all the time simultaneously, can prevent effectively that the additive from outwards wafting polluted environment, sneaking into the possibility of impurity in the reduction additive.
