Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0032] See also Figure 1-7 The utility model is a grading wheel for crushing large-particle materials, comprising an upper disk body 1; a plurality of top grooves 101 are arranged in a circumferential array at the bottom of the upper disk body 1, and a rotating blade 2 is snap-fitted in the top groove 101, and a lower disk body 3 is snap-fitted with the side surface of the rotating blade 2 located below the upper disk body 1; a plug-in hole 302 is arranged at the top of the lower disk body 3 to snap-fit ​​with the plurality of rotating blades 2, a limiting folding plate 201 is fixed on one side of the rotating blade 2, a first inclined surface 202 is arranged at the bottom of the limiting folding plate 201, and the top of the limiting folding plate 201 is in contact with the bottom of the lower disk body 3; two threaded rods 102 are fixed at the bottom of the upper disk body 1, and arc-shaped slots 203 are penetrated on one side of the plurality of rotating blades 2; two arc plates 4 are snap-fitted between the plurality of arc slots 203, and ear plates 401 are fixed on the side surfaces of the two arc plates 4, and a first limiting hole 402 slidingly matched with the threaded rod 102 is arranged at the top of the ear plate 401.

[0033] Specifically, a second limiting hole 301 which is slidably matched with the threaded rod 102 is formed on the top of the lower plate 3 .

[0034] Furthermore, the threaded rod 102 is located between the arc plate 4 and the lower plate 3 and is threadedly rotated with a threaded block 103 on its side surface.

[0035] The operation process of this embodiment is as follows: first, the two arc plates 4 are snap-fitted into the arc slots 203 formed through one side of the plurality of rotating blades 2, and then the plurality of top slots 101 formed at the bottom of the upper plate 1 are snap-fitted with the tops of the plurality of rotating blades 2, and at the same time, the two threaded rods 102 fixed at the bottom of the upper plate 1 are respectively plugged into the first limiting holes 402 formed on the two arc plates 4, and at this time, the two arc plates 4 can be fixedly connected by bolts. The assembly between the upper plate 1, the rotating blades 2 and the two arc plates 4 is realized. The top frame of the grading wheel is assembled, and then the two threaded blocks 103 are respectively threadedly rotated to fit the side surfaces of the two threaded rods 102, and finally the second limiting holes 301 opened on the lower plate 3 are plugged into the plurality of rotating blades 2.
