A capacity metering additional device based on an existing weighing metering coal feeder belongs to the field of weighing of coal feeders in thermal power generation, and is characterized in that a guide cylinder is mounted on a discharge port by increasing the distance between the discharge port of a bunker of the coal feeder and a weighing belt, and two parallel flexible baffle plates are arranged on the surface of the weighing belt, so that the discharge port can be sealed; a coal conveying cavity is formed between the two flexible baffles, an inclined coal pressing plate is arranged in the coal conveying cavity, the two sides of the coal pressing plate make contact with the two side walls of the coal conveying cavity, and in the coal conveying process of the weighing belt, coal at a coal falling point below the guide cylinder is evenly pressed and filled in the coal conveying cavity. By means of the measures, coal is conveyed in a regular rectangular strip shape in the coal conveying cavity of the weighin
