The powder collecting device is of a cone structure and is arranged in the shell, the upper end of the powder collecting device is a large opening, and the lower end of the powder collecting device is a small opening. The feeding and distributing device comprises a shaft sleeve and a plurality of spreading blades, wherein the spreading blades are radially and uniformly distributed on the circumferential surface of the shaft sleeve, and the shaft sleeve is arranged on the transmission shaft and is similar to a propeller structure. The lower end of the powder collecting device is positioned above the plurality of spreading blades. When the powder scattering device works, the scattering blades rotate under the driving of the transmission shaft, materials fall onto the scattering blades from the lower end of the powder collecting device with the cone structure, the materials are scattered around by the rotating scattering blades and thrown to the inner wall of the shell body to collide with the inner wall, and agglomerated fine powder in the materials is dispersed. Because the feeding and distributing device is similar to a propeller structure, one part of the material falling on the material scattering blades directly falls down from the material scattering blades, so that the part of the material cannot be dispersed, and the powder selecting efficiency is influenced. Meanwhile, the lower end of the powder collecting device is located above the scattering blades, the falling of the materials freely falls, and the materials are difficult to uniformly fall onto the scattering blades, so that the materials thrown from the scattering blades to the periphery are difficult to uniformly disperse, the dispersion of the materials is influenced, and the powder selecting efficiency is reduced.
