Abstract:
To restrain the occurrence of blocking-up in a tip side opening part of a blowing pipe in a blowing work machine.SOLUTION: A blowing work machine 1 comprises a blowing work machine body 3 and a blowing pipe member 50. The blowing work machine body 3 discharges air sucked in from an air suction part 3a from an air discharge part 4 by rotation of a blower fan 7 rotatingly driven by an engine 6. The blowing pipe member 50 comprises a base end side opening part 52 for making air discharged from the air discharge part 4 of the blowing work machine body 3 flow in and a tip side opening part 51 for jetting this flowed-in air. When a plane PN vertical to an axis AL of the blowing pipe member 50 is allowed to abut on the tip side opening part 51 of the blowing pipe member 50, air jetting passages β1, β2 are formed on both sides across abutting places α1, α2 between the tip side opening part 51 of the blowing pipe member 50 and the plane PN, and the air circulated in the blowing pipe member 50 is jetted to the outside of the blowing pipe member 50 by passing through the air jetting passages β1, β2 on both sides.SELECTED DRAWING: Figure 5A
