走行式清掃車用ダクト開閉装置。[Scope of Claim for Utility Model Registration] (1) A main brush that rotates at high speed and sweeps dust into a hopper, and dust that is kicked up into the brush chamber by this main brush and is sucked into a dust collection chamber and captured by a filter. In a traveling cleaning vehicle equipped with a vacuum fan for collecting air, an on-off valve is installed in the middle of the suction duct leading to the vacuum fan, which is opened and closed by rotating an operating handle. A duct opening/closing device for a traveling cleaning vehicle, characterized in that a switch operating means is provided for turning on the operating switch of the filter shaking device when a handle is rotated to close the opening/closing valve. (2) Claim (1) characterized in that a reed switch is used as an operating switch for operating the filter shaking device, and a magnet is attached to the operating handle of the on-off valve to turn the reed switch on and off. ) Duct opening/closing device for traveling cleaning vehicles. (3) Attach a return spring to the operating handle to which the on-off valve is attached, which exerts an elastic action to pull the operating handle, which has been rotated to the closed position of the on-off valve, back to the open position where the on-off valve normally opens the suction duct; Additionally, a positioning spring is elastically pressed onto the circumferential surface of the cam disc attached to the operating handle, which engages with an engagement groove formed in the circumferential surface to hold the operating handle in the open position. A duct opening/closing device for a traveling cleaning vehicle according to claim (1).
