PROBLEM TO BE SOLVED: To enable an air conveying system to be used in broader applications and to be available for a usage in which the system can be utilized in a plurality of purposes. SOLUTION: In the air conveying system 14, a suction duct for a blower 18m which sucks in a particle A through a suction hose 15, is provided with a separator-filter 27 for separating the sucked particle AS to be accumulated in a tank 20. Meanwhile, a discharge duct for the blower 18 is proved with a rotary feeder 22, where the particle A in the tank 20 is to join, and from where the joined particle A is to be subsequently discharged through the discharge duct 16. The air conveying system 14 is mounted on a self-propelled machine 1 self-propelling with the power from an engine 2, and driven by the power derived from the engine 2.
