The utility model discloses a lower feeder, wherein lower feeder includes a spiral shell, the inside reinforced axle that is provided with of spiral shell, and with a reinforced axle adaptation, be used for carrying the helical blade of powder, wherein, the cross section of reinforced axle is the square, helical blade's hole cross section also is the square. Make the reinforced axle of square into through the circular reinforced axle among the lower feeder to helical blade's the hole also corresponding square of adaptation with it that makes into, thereby need not the fixing bolt that unscrews when changing helical blade, alright directly take out helical blade, in addition, adopt the helical blade cooperation on nodular cast iron layer to make square cooperation into, and the helical blade material changes nodular cast iron into by potassium steel, can reduce the time of changing helical blade, and reduction in production cost, have high practicality. 本实用新型公开种下加料机，其中所述下加料机包括螺旋外壳，所述螺旋外壳内部设置有加料轴，以及与所述加料轴适配、用于输
