BACK PACK BLAST MACHINE
PROBLEM TO BE SOLVED: To provide a back pack blast machine capable of reducing size and noise.SOLUTION: The back pack blast machine comprises: a back pack frame having at least a back plate part 12 that fits along a back of an operator and allowing the operator to lift the back plate part 12 onto his or her back by a shoulder strap; motors 21A, 21B mounted on the back pack frame; a first fan 22A that is rotated by the motor; a second fan 22B different from the first fan 22A; and a blast pipe, which converges the blasts generated by the first fan 22A and the second fan 22B, respectively, rotated by the motor 21 into an introduction part 31a and blows the converged blast.SELECTED DRAWING: Figure 4
【課題】小型化と低騒音化の両立を図ることができる背負式送風作業機を提供する。【解決手段】背負式送風作業機は、作業者の背中に沿う背板部１２を少なくとも有し、背板部１２をショルダーストラップによって作業者の背中に背負うようにした背負フレームと、背負フレームに搭載した原動機２１Ａ，２１Ｂと、原動機により回転する第１ファン２２Ａと、第１ファン２２Ａと別体の第２ファン２２Ｂと、原動機２１によって第１及び第２ファン２２Ａ，２２Ｂを回転させたときに発生する各々の送風を導入部３１ａで合流させて送り出す送風管とを備えた。【選択図】図４
