Valve.
Further, the asphalt mixing plant additive metering device further includes the weighing hopper for having fixed setting
Fixed seat, the weighing sensor are connected in weighing hopper fixed seat, and weighing hopper is connected to below weighing sensor.
Further, it is provided with discharge duct below the weighing hopper, discharging control valve is provided on discharge duct.
Further, the weighing hopper is set to above mixing plant.
Further, the transition bucket is set to above weighing hopper.
Further, the asphalt mixing plant additive metering device further includes the transition bucket for having fixed setting
Fixed seat, the transition bucket are connected to by connector in transition bucket fixed seat.
Further, the asphalt mixing plant additive metering device further includes having automatic control system, institute
Stating automatic control system and weighing sensor can communicate to connect, and connect the control additive transfer pump, discharging control valve and
Discharging control valve.
From the above description of the utility model, it can be seen, compared with prior art, the utility model has the beneficial effects that：
Transition bucket is set by increase, can be used for secondary measurement, first pass through big flow discharge nozzle and sent to weighing hopper big flow
Material is switched to and is discharged tubule feeding by small flow, in transition bucket when injecting the amount of additive close to desirable value in weighing hopper
Additive flows into weighing hopper by the small flow of small flow discharging tubule under the effect of gravity, can effectively improve measuring accuracy, save
Raw material reduces waste.
Description of the drawings
Fig. 1 is the overall structure diagram of specific embodiment of the present invention；
Fig. 2 is the weighing hopper mounting structure schematic diagram of specific embodiment of the present invention.
In figure：1. weighing hopper, 2. transition buckets, 3. weighing hopper fixed seats, 4. transition bucket fixed seats, 5. weighing sensors, 6.
Feed pipe, 7. big flow discharge nozzles, 8. small flows discharging tubules, 9. discharging control valves, 10. discharge ducts, 11. discharging control valves,
12. connector.
Specific implementation mode
Below by way of specific implementation mode, the utility model will be further described.
Referring to Figures 1 and 2, a kind of asphalt mixing plant additive metering device of the utility model includes
Weighing hopper 1, the transition bucket 2 being set between feed end and weighing hopper 1, fixed setting weighing hopper fixed seat 3, fixed setting
Transition bucket fixed seat 4 and automatic control system.1 top of the weighing hopper is provided with weighing sensor 5,2 upper end of the transition bucket
Additive supply pump group is connected feed pipe 6, weighing hopper 1 is connected by big flow discharge nozzle 7 and by way of spill-over in terms of
1 feeding of batch box, 2 lower end of the transition bucket discharge the connection weighing hopper 1 of tubule 8 to 1 feeding of weighing hopper by small flow, and small flow goes out
It is provided with discharging control valve 9 on material tubule 8.
The weighing hopper 1 is set to above mixing plant.The weighing sensor 5 is connected in weighing hopper fixed seat 3, meter
Batch box 1 is connected to 5 lower section of weighing sensor.1 lower section of the weighing hopper is provided with discharge duct 10, and discharging is provided on discharge duct 10
Control valve 11.The transition bucket 2 is set to 1 top of weighing hopper.The transition bucket 2 is connected to transition bucket by connector 12 and fixes
On seat 4.The automatic control system can be communicated to connect with weighing sensor 5, and connect the control additive transfer pump, discharging
Control valve 9 and discharging control valve 11.
Referring to Figures 1 and 2, when the utility model is added agent metering, discharging control valve 9 is in closes shape at the beginning
State, additive squeeze into transition bucket 2 by additive supply pump group from feed pipe 6, and after transition bucket 2 fills, additive goes out from big flow
Expects pipe 7 enters weighing hopper 1.When injecting the amount of additive close to desirable value in weighing hopper 1,5 feedback signal of weighing sensor is given
Automatic control system, additive supply pump group shuts down, while automatic control system sends a signal to discharging control valve 9, goes out
