Novel belt weigher speed measuring device

The utility model relates to the technical field of mechanical equipment, in particular to a novel belt weigher speed measuring device which comprises a belt support, a belt body, an upper-layer carrier roller and a lower-layer carrier roller are installed on the belt support, the belt body is composed of an upper-layer belt and a lower-layer belt, the upper-layer carrier roller supports the upper-layer belt, and the lower-layer carrier roller supports the lower-layer belt. The lower-layer belt is supported by the lower-layer carrier roller; a support is installed above the belt support, a U-shaped groove is formed in the upper end of the support, a movable rod is rotationally connected to the U-shaped groove, and a rotating shaft is connected to one end of the movable rod. The speed measuring wheel is arranged on the lower surface of the upper-layer belt in a rolling manner, the upper-layer belt is relatively flat and almost has no jumping phenomenon, speed measuring pulse signals are more stable, metering a
