[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0030] Please refer to the attached Figures 1 to 4 As shown, a grading rotor of a grinding machine in an embodiment of the present utility model includes a rotating shaft 1. The rear end of the rotating shaft 1 is fixedly sleeved with a first-stage grinding wheel 2, and the front end of the rotating shaft 1 is fixedly sleeved with a second-stage grinding wheel 3. During use, the rotating shaft 1 is connected to the output shaft of the grinding machine. When the rotating shaft 1 rotates, it drives the first-stage grinding wheel 2 and the second-stage grinding wheel 3 to rotate at high speed, thereby grinding the material. Among them, the first-stage grinding wheel 2 is of a pin type structure. During use, the material is broken by the rotation and impact of the pin 232, and large-particle ceramic materials can be quickly broken, with high working efficiency. The second-stage grinding wheel 3 is of a worm wheel type structure, and has a stronger shearing and stirring effect during rotation, which can make the ceramic powder uniform.

[0031] The primary grinding wheel 2 includes two mounting sleeves 21. Between the outer ends of the two mounting sleeves 21, a plurality of connecting cross bars 22 are fixedly connected at equal intervals. The connecting cross bar 22 includes a rod body 221. A plurality of mounting holes 223 are evenly formed at intervals on the inner side of the rod body 221. A plurality of detachable pin rods 23 are connected to the inner side of the rod body 221.

Both sides of the baffle 231 are fixedly connected to the rod body 221 through third mounting bolts 233. When the primary grinding wheel 2 is in use, the pin rod 232 rotates to stir and impact the material. At the same time, the pin rod 232 is connected and fixed to the rod body 221 through the third mounting bolt 233. When the pin rod 232 is worn, the corresponding third mounting bolt 233 can be unscrewed to detach the worn pin rod 232 alone. The modular structure enables the replacement of only the worn pin rod 232 without replacing the entire primary grinding wheel 2, which can reduce the replacement cost.

[0033] The secondary grinding wheel 3 includes two inner half rings 31. The inner half rings 31 are fixedly connected to the rotating shaft 1 through fifth mounting bolts 36.

A plurality of rib plates 34 are fixedly connected to the outer side of the connecting plate 32. Two rib plates 34 that cooperate with each other up and down are fixedly connected through fourth mounting bolts 35. The secondary grinding wheel 3 also adopts a detachable structure, consisting of two upper and lower component parts. After unscrewing the fifth mounting bolt 36, the secondary grinding wheel 3 can be detached. The split structure is also convenient for disassembly and installation, and the efficiency of installation and disassembly is high.

[0034] A plurality of through openings 37 are evenly formed at intervals on the outer surface of the outer half ring 33. The provided through openings 37 facilitate the rotation to disperse the material, which can improve the grinding effect.

[0035] The mounting sleeve 21 includes two half sleeves 211. An extending arm 212 is fixedly connected to the outer end of the two half sleeves 211. A mounting groove 213 is formed at the outer end of the extending arm 212. Both ends of the rod body 221 are respectively clamped between the two mounting grooves 213 and are fixedly connected to the mounting groove 213 through second mounting bolts 222. The rod body 221 is fixedly connected between the two mounting grooves 213 through the second mounting bolts 222. After installation, the stability is strong, the strength is high, and it can also be disassembled. During subsequent maintenance, it can be replaced individually, further reducing the replacement cost during subsequent maintenance.

[0036] Both ends of the half set 211 are fixedly connected with mounting heads 215. The mounting heads 215 of the two half sets 211 cooperate with each other and are fixedly connected by bolts. The half set 211 and the rotating shaft 1 are fixedly connected by the first mounting bolts 214. The mounting sleeve 21 also adopts an up-and-down split mounting structure, which is convenient for installation and disassembly.

[0037] The rod pin 232 is made of cemented carbide. The rod pin 232 made of cemented carbide has high hardness, wear resistance and corrosion resistance, and is suitable for grinding high-hardness materials.
