Example 1

[0022] Reference Figures 1 to 2 As shown, one embodiment of the present invention provides a graded wheel structure, comprising: Top plate 1, wherein a plurality of first slots 11 are provided on the top plate 1; The base plate 2, corresponding to the first slot 11, is also provided with a plurality of second slots 21; A plurality of grading blades 3, one end of the plurality of grading blades 3 is engaged in a corresponding first slot 11, and the other end of the plurality of grading blades 3 is engaged in a corresponding second slot 21, forming a grading cavity; In this embodiment, the first slot 11 and the second slot 21 are arranged correspondingly to each other. When the first slot 11 and the second slot 21 are opened, a certain angle is set or no angle is set, which can be set according to the requirements of different product particles. In this embodiment, the first slot 11 and the second slot 21 are opened at a set angle, so that when the grading blade 3 is inserted, the grading blade 3 has a certain slope, which can reduce the resistance of the grading blade to the material grading and screening. At the same time, the grading blade 3 is arranged around the first slot 11 and the second slot 21, and the multiple grading blades 3 form a grading cavity. Example 2

[0023] Reference Figures 1 to 6 As shown, in this embodiment, in order to fix the grading sheet based on Embodiment 1, so that the grading sheet will not fly out or be damaged due to loosening during high-speed rotation, the specific solution is as follows: The graded wheel structure also includes: Upper end plate 4, which is disposed on top plate 1, is used to fix one end of the plurality of graded blades 3 to the snap-fit ​​joint of top plate 1; The lower end plate 5 is disposed on the base plate 2 and is used to fix the other end of the plurality of grading blades 3 to the snap-fit ​​joint of the base plate 2; the grading wheel structure also includes: an inner ring sleeve 9, which is disposed between the upper end plate 4 and the lower end plate 5, and the upper end plate 4 and the lower end plate 5 are respectively provided with through holes 41 corresponding to the inner ring sleeve 9; the inner ring sleeve 9 is also provided with a guide groove 91; the upper end plate 4 is also provided with at least two discharge ports 42; the grading wheel structure also includes: a plurality of dispersing wheels 6, which are disposed on the lower end plate 5. The upper end plate 4 and the lower end plate 5 are provided with fixing rings 7 on all four sides. The fixing rings 7 are used to fix the outer side of the engagement point between the grading blade 3 and the top plate 1 and the bottom plate 2, respectively, so that the grading blade 3 is fixed in the first slot 11 and the second slot 21. The surface of the upper end plate 4 near the fixing rings 7 is used to fix the top end of the grading blade 3 in the first slot 11. The surface of the lower end plate 5 near the fixing rings 7 is used to fix the bottom end of the grading blade 3 in the second slot 21. Secondly, the inner ring sleeve 9 is used to mount the drive shaft. In addition, a guide groove 91 is provided in the inner ring sleeve 9 to facilitate the installation of the drive shaft. When the drive shaft rotates, it will drive the inner ring sleeve 9 to rotate. At the same time, the upper end plate 4 and the lower end plate 5 will rotate. The upper end plate 4 and the lower end plate 5 will drive the top plate 1 and the bottom plate 2 to rotate, which will also drive the grading blades 3 to rotate. That is, the grading blades 3 are used for grading and screening. At the same time, when the lower end plate 5 rotates, the dispersing wheel 6 also rotates, which evenly disperses the material to the circumference and prevents the material from accumulating at the lower end of the grading wheel. Meanwhile, after the material is graded by the grading blades 3, the refined material can enter the finished product area through the discharge port 42 or be output through the discharge port 42. In this embodiment, there are 4 discharge ports 42, but 2 can also be set as needed. The setting of the discharge ports 42 is not only to facilitate the output of materials, but also to separate the output of materials, thereby further avoiding the pressure of the drive shaft rotation. Example 3

[0024] Reference Figures 1 to 7 As shown, based on this embodiment 2, in order to further fix and support the grading sheet; The graded wheel structure further includes: a plurality of support rods 8, the plurality of support rods 8 being disposed between the top plate 1 and the bottom plate 2, the upper end and / or lower end of the plurality of support rods 8 being provided with a conical surface 81, and the middle sides of the plurality of support rods 8 being provided with two grooves 82. The support rod 8 is set between the top plate 1 and the bottom plate 2, which connects the top plate 1, bottom plate 2, upper end plate 4, and lower end plate 5 into a whole to fix and support the grading plate. This disperses or reduces the pressure on the grading plate, thereby preventing damage to the grading plate. In addition, the conical surface 81 is set at the upper end and / or lower end of the support rod 8, which reduces the resistance to the material during the material grading process, thereby reducing the power consumption of the drive shaft. Furthermore, the two grooves 82 are provided on both sides of the middle of the support rod 8, which can be used to clamp the tool when installing the support rod 8, making it easier to install and fix the support rod 8.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
