PURPOSE:To contrive efficient chemical spraying by mounting the titled sprayer to a self-traveling working machine or the like, permitting feeding of water to a liquid tank, stirring and spraying with a simple operation by one unit of the device and permitting desired selection of adequate spraying patterns according to the configuration of the area to be sprayed. CONSTITUTION:The liquid tank 2 is disposed on a stand of the self-traveling working machine or the like and one end of a liquid force-feed pump 8 is positioned in the tank 2. A suction port 9 of the pump 8 is communicated through a selector valve 15 with the inside of the tank 2. A discharge port 10 of the pump 8 is further connected through a selector valve 25 to a spray nozzle 13. As a result, the feeding of the water to the liquid tank and the stirring and spraying thereof can be made with the simple operation by means of one unit of the device when the device is mounted to the highly mobile self-traveling working machine or the like, in addition, the efficient chemical spraying by selecting the adequate spraying pattern according to the configuration of the area to be sprayed, as desired, is permitted.
