PROBLEM TO BE SOLVED: To provide a simple fly ash automatic sampling device with which it is possible to supply the fly ash sampled from a fly ash chute to an addition amount determination device by only a prescribed amount.SOLUTION: The fly ash automatic sampling device has: a sampling unit 10 for sampling fly ash H from a fly ash chute Y; a hopper unit 20 for storing the fly ash sampled by the sampling unit; a fixed amount supply unit 30 for letting fly ash in the hopper unit flow out in a fixed amount; and a control unit 50 for supplying a prescribed amount of fly ash H1 for examination from the fixed amount supply unit to an addition amount determination device 2 when each addition amount determination device enters a mode ready to accept fly ash, letting fly ash in the hopper unit that is not used for examination be discharged to the outside via the addition amount determination device when each addition amount determination device enters first and second pass modes for letting fly ash pass through, and causing the sampling unit to store new fly ash from the fly ash chute into the hopper unit when each addition amount determination device enters a standby mode between the first and second pass modes.SELECTED DRAWING: Figure 2 |
