[0026] Adopting the above scheme: By setting the fan blade member 51, when adding powder into the first sieve plate 2, the fan blade device 5 rotates to disperse the powdered body that has coagulated into blocks, and then when it falls into the second sieve plate 3, it will not form blocks.

[0027] Reference Figure 2 , Figure 3 and Figure 4 , the fan blade member 51 includes a connecting block 511, a clamping groove 512 and a blade plate 513. The connecting block 511 is sleeved on the middle surface of the rotating shaft 43 and is fixedly connected to the rotating shaft 43. The number of clamping grooves 512 is three, and they are evenly formed on the upper surface of the connecting block 511. The number of blade plates 513 is three, and they are respectively clamped in the three clamping grooves 512.

[0028] Adopting the above scheme: By setting the clamping groove 512 on the connecting block 511 to clamp and fix the blade plate 513, it has the function of facilitating the staff to disassemble and clean the blade plate 513 in subsequent work.

[0029] Reference Figure 2 and Figure 4 , the fixing member 52 includes a thread 521 and a cover plate 522.
