PROBLEM TO BE SOLVED: To provide a blasting work machine that prevents icing of a vaporizer in a lower outdoor temperature environment, and suppresses rise of temperature of the vaporizer.SOLUTION: A blast work machine 1 blows out an air flow generated by a rotating fan from an outlet of a fan case 30. An engine 20 and a vaporizer 50 are laid out opposite a rear side surface 32a of the fan case 30, and an engine cover 24 (partitioning part) is installed to partition a space for installing the engine 20 and a space for installing the vaporizer 50. A ventilation hole 38 that pierces through a rear wall part 32 of the fan case 30 is formed on the rear side surface 32a, at an area facing the space for installing the vaporizer 50, and the ventilation hole 38 opens toward the vaporizer 50.SELECTED DRAWING: Figure 1 |
