To protect a driver from an obstacle from the front during spray-traveling and protect the driver at the time of vehicle rollover.SOLUTION: During spray-traveling of a speed sprayer 100, an upper frame 13b is rotated forward from an upright position, and a connection frame 13c is tilted forward to a forward tilt position located in front of a front end of a seat 5 in plan view. Thus, a safety area S2 against an obstacle such as a branch from the front during spray-traveling is formed behind an area surrounded by a forward-tilted gate-shaped frame 13x, thereby ensuring safety of a lower face part substantially below the nose, the neck, the chest or the like of a driver D seated on the seat 5 and performing driving operation. In addition, a safety area S3 during vehicle rollover is formed below a virtual line VL2 connecting an upper portion of the forward-tilted gate-shaped flame 13x and an upper portion of a tip end portion of the speed sprayer 100 and below the area surrounded by the forward-tilted gate-shaped flame 13x, thereby also ensuring safety of the driver D seated on the seat 5 and performing driving operation at the time of vehicle rollover during spray-traveling.SELECTED DRAWING: Figure 8
【課題】散布走行中の前方からの障害物に対する運転者の保護及び車両横転時の運転者の保護を図る。【解決手段】スピードスプレーヤ100の散布走行中において、上部フレーム13bを直立ポジションから前方へ回動し平面視において連結フレーム13cが座席5の前端より前方に位置する前傾ポジションへ前傾させることによって、前傾した門形フレーム13xで囲まれる領域より後方に、散布走行中の前方からの枝等の障害物に対する安全領域S2を形成し、座席5に着座し運転操作する運転者Dの概ね鼻から下の顔部分、首、胸等の安全を確保する。加えて、前傾した門形フレーム13xの上部とスピードスプレーヤ100の先端部の上部とを結ぶ仮想線VL2より下方及び前傾した門形フレーム13xで囲まれる領域より下方に、車両横転時の安全領域S3を形成し、座席5に着座し運転操作する運転者Dの散布走行中の車両横転時の安全も確保する。【選択図】図8
