BLASTING DEVICE

PROBLEM TO BE SOLVED: To provide an easy-to-carry blasting device capable of reducing arrangement manhours. SOLUTION: This blasting device 10 rotates a suction pipe 14 at a specified frequency by driving force of a motor 16 in a sponge blast medium 32 reserved in a container 12. It is operated so that a lower part suction port 38 advances, while rotating, to a part where the sponge blast medium 32 is depleted while sucking the sponge blast medium 32 from the lower part suction port 38 of the suction pipe 14 by making use of an ejector effect generated by supplying compressed air to an ejector nozzle 20 from an air compressor 22. The sponge blast medium 32 sucked by the ejector effect is guided to a hose 18 connected to the suction pipe 14 through a rotating coupler 48 and jetted from a jetting port 56 of the ejector nozzle 20.
