PROBLEM TO BE SOLVED: To provide a particulate matter spraying vehicle capable of detecting a spray volume when making particulate matters stored in a storage part flow down to spray them to the ground.SOLUTION: The particulate matter spraying vehicle includes: a particulate matter spraying device that makes the particulate matters stored in the storage part flow down to spray them to the ground; an impact detection sensor 9 that has a sensor surface 90 colliding with the particulate matters flowing down a particulate matter flow-down path; and a spray volume evaluation part 4 that calculates a particulate matter spray volume per unit time, a particulate matter spray volume per unit area, or both spray volumes on the basis of detection signals of the impact detection sensor 9. |
