Abstract
A continuous quantitative discharging device comprising a material reserving chamber for storing material continuously supplied from a material supply means; a material storage tank having at a top a material inlet separated from said material reserving chamber for storing material fallen from said material reserving chamber and having at a lower part a discharge means capable of continuously and quantitatively discharging the stored material therefrom; a load cell type mass weighing part having a carrying arm secured to only said material storage tank in said material storage tank and supporting said carrying arm by a load cell provided on a support frame separated from said material storage tank in a non-contact state; and a controller for monitoring the weighed value of said load cell and controlling the discharge of material from said discharge means and/or the supply of material into said material storage tank.
