SELF-PROPULSION SPRAY MACHINE AND SPRAY METHOD

To provide a self-propulsion spray machine where an injector is easily moved to an arbitrary work position to stably deal with reaction force accompanying the spraying of a fluid by using an air thrust device.SOLUTION: A self-propulsion spray machine having an air thrust device is provided with a first injector capable of spraying a fluid on a work plane and a second injector capable of spraying the fluid to be opposite to the first injector. A spray method using the self-propulsion spray machine includes a step of moving the self-propulsion spray machine to the vicinity of the work plane by thrust generated by the air thrust device, a step of supplying the fluid to the first injector and the second injector and a step of moving the self-propulsion spray machine along the work plane by the thrust generated by the air thrust device.SELECTED DRAWING: Figure 1 【課題】空気推力装置を用いることによって噴射装置を任意の作業位置に容易に移動させ、かつ流体の吹き付けに伴う反力に安定して対処する。【解決手段】空気推力装置を有する自己推進式吹付機は、作業面に流体を吹き付けることが可能な第１の噴射装置と、第１の噴射装置とは逆向きに流体を吹き付けることが可能な第２の噴射装置とを備える。自己推進式吹付機を用いた吹付方法は、自己推進式吹付機を空気推力装置が発生させる推力によって作業面の近傍まで移動させる工程と、第１の噴射装置および第２の噴射装置に流体を供給する工程と、自己推進式吹付機を空気推力装置が発生させる推力によって作業面に沿って移動させる工程とを含む。【選択図】図１
