[0021] like Figure 1 and Figure 2As shown, a second spacer ring 14 is provided adjacent to the upper and lower positions of the first spacer ring 5, and grooves for assembling the blade body 6 are respectively provided at the edge positions of the second spacer ring 14 and the first spacer ring 5 and the edge positions of the top surface of the limiting chassis 16. An inner card seat 4 is provided around the middle and upper positions of the inner sides of the first spacer ring 5 and the second spacer ring 14, and the upper and lower groups of inner card seats 4 are connected by guide pillars 15. The guide pillars 15 and the rotating cage 1 are fixedly connected. After multiple guide pillars 15 are simultaneously connected to multiple groups of upper and lower inner card seats 4, they will mainly play the role of connecting the first spacer ring 5 and the second spacer ring 14 together; the outer wall of the rotating main shaft 2 is fixedly connected with connecting rods 3 in a circle, and adjacent groups of connecting rods 3 and connecting rods A single inner socket 4 of the first spacer ring 5 is fixedly connected, and a plurality of groups of connecting rods 3 are connected to form a hexagonal star structure. When the plurality of connecting rods 3 are simultaneously connected to the rotating main shaft 2 and the inner socket 4 connected to the first spacer ring 5 and form a hexagonal star structure, the entire powder classifier rotor can enhance the structural stability of the upper end position of the rotor through this structure; the blade body 6 is distributed in an annular array structure along the center point of the rotating main shaft 2, a group of first ear plates 7 are respectively fixedly connected to the first spacer ring 5 with bolts, and the boss 8 is arranged between the group of first ear plates 7.
