Bulk material high-precision feeding method based on multiple hoppers

The invention discloses a high-precision bulk material feeding method based on multiple hoppers, which comprises the following steps of: 1, determining several weighing bins for weighing according to the total feeding amount, determining the weighing amount of each weighing bin, and when the weighing amount of the weighing bin is not equal to the weighing full scale of the bin, determining the weighing amount of the weighing bin; the stock bin is remembered, and the weight to be weighed of the stock bin is subjected to full scale correction to reach the weight to be weighed; and 2, weighing is started, the weighed stock bins are continuously transferred out of the discharging gates of the storage bins and conveyed into the empty stock bins to the discharging gates of the storage bins, chute gates of the weighing stock bins transferred out of the discharging gates of the storage bins are opened, the weighed stored materials are conveyed to material receiving equipment, and the weight of the weighing stock bins
