High-precision decrement scale for viscous and wet materials

The invention relates to the technical field of weighing and metering, in particular to a high-precision decrement scale for viscous and wet materials, which comprises a stock bin, a weighing sensor, a vertical loosening device, a shaftless spiral discharge auxiliary device and a discharge belt conveyor, the shaftless spiral discharge auxiliary device is mounted at a discharge port of the stock bin, and the discharge belt conveyor is arranged below the discharge port of the stock bin. The stock bin is designed to be cylindrical, and the side wall of the stock bin is perpendicular to 90 degrees, so that materials on an inclined surface can be prevented from being adhered; the vertical loosening device loosens the materials in the stock bin and assists the stock bin in discharging at the same time. Materials in the stock bin are collected to a discharge port of the stock bin through a loosening scraper at the bottom of the vertical loosening device, the shaftless spiral discharging auxiliary device assists the
