[0021] Please refer to Figures 1-4 , an embodiment provided by the present utility model: a high-strength wear-resistant grinding disc structure for a ore grinder, including a mounting plate 1 and a grinding disc 2. A plurality of grinding blocks 3 are fixedly connected to the bottom of the grinding disc 2, and wear-resistant sheets 4 are fixedly connected to the bottoms of the plurality of grinding blocks 3. An installation groove is provided on the mounting plate 1, and the grinding disc 2 is arranged in the installation groove. Plug plates 5 are fixedly connected to both sides of the top end of the grinding disc 2. Slots corresponding to the plug plates 5 are provided on the mounting plate 1. A rotating cavity is provided in the plug plate 5, and a threaded rod 6 is rotatably connected in the rotating cavity. A pressing plate 7 is threadedly sleeved on the threaded rod 6. Wedge plates 8 are provided on both sides of the pressing plate 7. A push plate 9 is fixedly connected to one side of the wedge plate 8. A plurality of first springs 10 are fixedly connected between one side of the push plate 9 and the inner wall of the rotating cavity. A limiting block 11 is fixedly connected to one side of the push plate 9. A through hole corresponding to the limiting block 11 is provided on the plug plate 5. The top end of the threaded rod 6 penetrates through the plug plate 5 and is fixedly connected to a rotating block 12. A clamping rod 13 is slidably inserted into one end of the rotating block 12. A plurality of card slots corresponding to the clamping rod 13 are provided at the top end of the plug plate 5. An anti-detachment block 14 is fixedly sleeved on one end of the clamping rod 13. Specifically, the grinding disc 2 is embedded and installed in the installation groove on the mounting plate 1. At this time, the plug plate 5 is inserted into the slot. Then, the rotating block 12 is rotated to drive the threaded rod 6 to rotate in the plug plate 5. When the threaded rod 6 rotates, the pressing plate 7 threadedly sleeved thereon moves downward. At this time, the pressing plate 7 presses the wedge plate 8 to move from the narrow side to the wide side. At the same time, the wedge plate 8 pushes the push plate 9 to move, and the push plate 9 pushes the limiting block 11 to extend to fix the position of the plug plate 5. When the sliding clamping rod 13 is inserted into the corresponding card slot, the rotation of the threaded rod 6 is fixed.

[0022] In this embodiment, a second spring 15 is sleeved on the clamping rod 13. The two ends of the second spring 15 are respectively abutted against the anti - detachment block 14 and the rotating block 12, which facilitates the clamping rod 13 to rebound into the card slot. A plurality of anti - slip lines are arranged obliquely on the outer side wall of the rotating block 12 to increase the rotational friction and avoid slipping. Rubber plates 16 are fixedly connected to the inner tops of both ends of the mounting plate 1 to increase the buffering force between the mounting plate 1 and the grinding disc 2. Two symmetrically arranged telescopic rods 17 are fixedly connected to the top end of the pressing plate 7, and the telescopic rods 17 are fixedly connected to the inner top of the inserting plate 5 to prevent the pressing plate 7 from revolving with the threaded rod 6. The two ends of the pressing plate 7 are both arranged in an arc shape to reduce the pressing resistance.

[0023] Working principle: First, the grinding block 3 on the bottom of the grinding disc 2 performs grinding. Wear - resistant sheets 4 are installed on the grinding block 3 to improve wear resistance. The grinding disc 2 is embedded in the installation groove on the installation plate 1. At this time, the inserting plate 5 is inserted into the slot. Then, the rotating block 12 is rotated to drive the threaded rod 6 to rotate in the inserting plate 5. When the threaded rod 6 rotates, the pressing plate 7 sleeved on the threaded rod 6 moves downward accordingly. At this time, the pressing plate 7 moves the pressing wedge plate 8 from the narrow side to the wide side. At the same time, the wedge plate 8 pushes the push plate 9 to move, and the push plate 9 pushes the limiting block 11 to extend to fix the position of the inserting plate 5. When the sliding clamping rod 13 is inserted into the corresponding card slot, the rotation of the threaded rod 6 is fixed.
