Impact plate belt scale and weighing method thereof

The invention discloses an impact plate belt scale and a weighing method thereof, which solve problems of low measurement accuracy and poor stability of the existing belt scale. The impact plate beltscale comprises a speed sensor (3) arranged on conveying belt machine (1), wherein a conveyed material (6) is conveyed on a conveying belt of the conveying belt machine (1). The impact plate belt scale is characterized in that a force and weight measurement sensor rack (8) is arranged in front of a machine head roller (2) of the conveying belt machine (1), a force and weight measurement sensor (4)is installed on the force and weight measurement sensor rack (8), an impact plate (5) is installed at a force measurement end of the force and weight measurement sensor (4), the force and measurementsensor (4) and the speed sensor (3) are electrically connected with a weighting instrument (7). The impact plate belt scale achieves accurate measurement for the amount of a bulk material conveyed bythe belt via a simple struc
