To provide a spray work machine in which a spray nozzle positioned at an outermost side when extending and contracting a side boom can spray different amount of agent from the other spray nozzles.SOLUTION: A spray work machine comprises: a liquid spraying device 10 which is arranged at a lateral side of a traveling vehicle body 1 to spray liquid formation, and which is extendable; and a plurality of discharging devices 120 which are arranged by prescribed intervals in the liquid spraying device 10 to perform on and off operation of discharging liquid formation. The discharging devices 120 are turned to be open states from a base part side in order when the liquid spraying device 10 is extended, and turned to be closed states from an end side in order when the liquid spraying device is shrunken. When extension of the liquid spraying device 10 is suspended, the discharging device 120 switched at the end becomes an intermediate state between the open state and the closed state.SELECTED DRAWING: Figure 19 【課題】サイドブームの伸縮操作時に最外側に位置する散布ノズルから、他の散布ノズルとは異なる量の薬剤を散布し得る散布作業機を提供すること。【解決手段】走行車体１の側方に液剤を散布する液剤散布装置１０を設け、液剤散布装置１０は液剤の放出を入切する放出装置１２０を所定間隔ごとに備え、液剤散布装置１０を伸縮可能とし、放出装置１２０は、液剤散布装置１０の伸長により基部側から順番に開状態に切り替えられると共に、収縮により端部側から順番に閉状態に切り替えられる構成とし、液剤散布装置１０の伸縮を停止させると、最後に切り替えられる放出装置１２０は開状態と閉状態の中間状態となる構成とする。【選択図】図１９
