a shoveling plate, arranged on an inner wall of the drum and extending from an inlet end of the drum towards an interior of the drum, the shoveling plate being disposed obliquely with respect to a generatrix parallel to the axis of the drum,
wherein the shoveling plate comprises:
a first shoveling plate, extending from the inlet end of the drum towards the interior of the drum; and
a second shoveling plate disposed side by side with the first shoveling plate along an axis of drum and located inwardly relative to the first shoveling plate, the second shoveling plate being connected to the first shoveling plate, an included angle between the second shoveling plate and the generatrix of the drum being smaller than an included angle between the first shoveling plate and the generatrix of the drum,
wherein the nozzle faces the second shoveling plate to spray the liquid flavor to tobacco shreds thrown down by the second shoveling plate,
wherein the shoveling plate further comprises a third shoveling plate disposed at an end of the second shoveling plate away from the first shoveling plate, a distance between an end of the third shoveling plate away from the inner wall of the drum and the inner wall being larger than a distance between an end of the second shoveling plate away from the inner wall and the inner wall to block tobacco sheds moving towards an outlet end of the drum under impact of the liquid flavor and/or the liquid flavor,
wherein the distance between a top of an end of the third shoveling plate close to the second shoveling plate and the inner wall is smaller than the distance between the top of an end of the third shoveling plate away from the second shoveling plate and the inner wall.
