ポンプ用ホッパの生コンレベル検知装置。An electrode is provided in the hopper of the concrete pump in contact with the fresh concrete placed at a level higher than the opening of the fresh concrete transfer cylinder that communicates with the hopper, and is electrically insulated from the hopper. An electric circuit is constructed by connecting a power source that flows a detection current between the electrode and the hopper via the ready-mixed concrete in the hopper. A timer that automatically stops the concrete pump after the time has elapsed, and a reversing switch contact that is installed in parallel with the contact of this timer and that enables the concrete pump to reverse when the concrete pump is stopped by the timer. A fresh concrete level detection device for a concrete pump hopper featuring:
