The invention discloses a stiff aphid stripping device. The stiff aphid stripping device comprises a conveying belt, wherein a tobacco leaf feeding position, a synchronous fixing module, a washing-brushing module, a stiff aphid collecting module and a tobacco leaf discharging position are sequentially arranged along the conveying belt. The synchronous fixing module comprises a rotating device anda compression strip and is used for compressing tobacco leaves on the surface of the conveying belt. The washing-brushing module strips stiff aphids from the surfaces of the tobacco leaves in the waysof washing and roll-brushing. By means of automatic stream line operation, labor can be saved, stiff aphids can be efficiently and economically stripped from the tobacco leaves, and then drying, impurity removal and collection are performed; the obtained stiff aphids are low in damage rate and high in separation efficiency.
