The invention relates to the technical field of combined scales, in particular to a rotary charging combined scale. In the prior art, a material on the combined scale falls down from a discharging outlet through vibrating of a vibration disc, due to the fact that the viscous material is prone to adhering to the wall, the conveying efficiency is low, and the weighing precision is not high. In orderto solve the problems, the technical scheme is adopted, specifically, the rotary charging combined scale comprises a machine frame, a rotary charging mechanism, double-screw conveying mechanisms, side scraping type hoppers and a collecting hopper, wherein the rotary charging mechanism, the double-screw conveying mechanisms, the side scraping type hoppers and the collecting hopper are arranged onthe machine frame from top to bottom in sequence; the upper portion of the rotary charging mechanism is provided with an opening, and the periphery of the bottom of the rotary charging mechanism is uniformly provided with a plurality of discharging outlets; and the double-screw conveying mechanisms, the side scraping type hoppers and the discharging outlets are the same in quantity and correspondone by one in position. The rotary charging combined scale provided by the invention comprises the rotary charging mechanism, the double-screw conveying mechanisms and the side scraping type hoppers which are different from those in the prior art, the defect that an existing combined scale cannot precisely weigh a viscous material is overcome, and precise weighing is achieved.
