To suppress variation in dust collection performance of a dust collecting device with a simple configuration while reducing vehicle cost even if the dust collecting device is provided.SOLUTION: A road surface cutting vehicle includes: conveyor hydraulic motors M1, M2; a conveyor hydraulic pump 31 capable of pumping hydraulic oil to the conveyor hydraulic motors M1, M2 via a conveyor hydraulic control valve 32; a return line 36 connected to the conveyor hydraulic control valve 32 and returning hydraulic fluid to a hydraulic fluid tank 30; a suction hydraulic motor M3 for driving a suction device; a suction device pipe line 38 connected to the return line 36 and supplying hydraulic oil pressure-fed from the conveyor hydraulic pump 31 to the suction hydraulic motor M3; and a bleed-off circuit for returning hydraulic oil to the hydraulic oil tank 30 without passing through the conveyor hydraulic control valve 32 or the conveyor hydraulic motor. A bleed-off flow path 80 is connected to a pipeline part 36A in the return line 36 upstream of the position where the suction device pipe line 38 is connected.SELECTED DRAWING: Figure 3
【課題】集塵装置を装備しても車両コストを低減しつつ、簡易な構成で集塵装置の集塵性能の変動を抑制する。【解決手段】コンベア用油圧モータＭ１、Ｍ２と、コンベア用油圧モータＭ１、Ｍ２に対しコンベア用油圧制御弁３２を介して作動油を圧送可能なコンベア用油圧ポンプ３１と、コンベア用油圧制御弁３２に接続し作動油を作動油タンク３０へ戻す戻り管路３６と、吸引装置を駆動する吸引用油圧モータＭ３と、戻り管路３６に接続してコンベア用油圧ポンプ３１から圧送された作動油を吸引用油圧モータＭ３に供給する吸引装置用管路３８と、コンベア用油圧制御弁３２及びコンベア用油圧モータを経由せずに作動油を作動油タンク３０に戻すためのブリードオフ回路と、を備え、ブリードオフ流路８０は、戻り管路３６における、吸引装置用管路３８が接続する位置よりも上流の管路部分３６Ａに接続する。【選択図】 図３
