Belt scale frame of stacker-reclaimer

The invention discloses a belt scale frame of a stacker-reclaimer. Comprising two parallel length adjusting mechanisms which are adjusted in the length direction of a stacker-reclaimer belt and a width adjusting mechanism which is adjusted in the width direction of the stacker-reclaimer belt. The clamping mechanisms are arranged at the two ends of the inner sides of the two length adjusting mechanisms and used for clamping a stacker-reclaimer belt, the weighing mechanisms are arranged on the two sides of the top ends of the two length adjusting mechanisms, and the width adjusting mechanism is arranged in the center between the two length adjusting mechanisms. The top end of the weighing mechanism is provided with a self-adaptive tray used for placing weighed materials, and the length adjusting mechanism and the width adjusting mechanism are arranged to be matched with the clamping mechanism and the weighing mechanism for use, so that the device can adapt to more stacker-reclaimer belts and is not limited any
