- 機械本体の前部で受入れ該機械本体の後部に搬送したアスファルト合材を、スクリューで拡げた後、伸縮による舗装幅可変のスクリードで舗装面に敷き均すとともに、該舗装幅可変のスクリードは所要の背圧の圧油がロッド側に供給されたリフトシリンダにより所要の作業角が保持されるように設定が行われている道路舗設機において、
前記スクリードの舗装幅を検出する舗装幅検出手段と、該舗装幅検出手段で検出された舗装幅の増減に応じて減増するように前記背圧を調整する背圧調整手段とを有することを特徴とする道路舗設機におけるスクリード用リフトシリンダの背圧可変機構。 - 上記背圧調整手段は、上記舗装幅検出手段で検出された舗装幅の増減に応じて減増するアシスト圧を発生させ、該発生させたアシスト圧の圧油を上記所要の背圧の圧油に加えるアシスト圧調整手段で構成してなることを特徴とする請求項1記載の道路舗設機におけるスクリード用リフトシリンダの背圧可変機構。
- 上記アシスト圧調整手段は、上記舗装幅に対応した制御信号を演算し出力するコントローラと、前記制御信号に応じた駆動信号を出力する制御量指令部と、ポンプからの圧油を前記駆動信号に応じたアシスト圧に調整する比例電磁式リリーフ減圧弁とを具備することを特徴とする請求項2記載の道路舗設機におけるスクリード用リフトシリンダの背圧可変機構。
