Rotating discs, cylinders, cones, flat plates, oilstones, thin plates, tubes, rings and specially made shaped grinding discs can all be used as grinding tools to grind materials by rotation.

[0003] However, most of the grinding discs currently on the market are integrally formed, with a protruding grinding part on the top. During long-term use, some grinding parts are severely worn. If they are directly replaced at this time, there will be a waste for the undamaged grinding parts because they cannot be fully utilized. If they are not replaced, the damaged grinding parts will not be able to play a grinding role, which will reduce the grinding effect of the entire grinding disc. For this reason, a grinding disc is specially provided to solve the above problem. Utility Model Content

[0023] The embodiment of the present application solves the problem of an integrally formed grinding disc by providing a grinding disc. When certain grinding parts are severely worn, if they are directly replaced, there will be a waste for fully utilizing the undamaged grinding parts. If they are not replaced, the damaged grinding parts will not be able to perform the grinding function.

[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0025] The embodiment of the utility model discloses a grinding disc.

[0026] According to the attached Figure 1As shown in Figure 5, it includes a rotating grinding disc frame 1 and a plurality of grinding blocks 2 arranged inside the rotating grinding disc frame 1. The grinding blocks 2 are movably inserted into the interior of the rotating grinding disc frame 1. A fixed shaft 15 is movably inserted into the interior of the rotating grinding disc frame 1. A connecting block 21 is fixedly welded to the bottom of the grinding block 2. The fixed shaft 15 passes through the connecting block 21. A fixed bracket 3 is provided outside the rotating grinding disc frame 1. The fixed bracket 3 includes;

[0027] The fixed ring 31, the maintenance opening groove 35 and the sliding stopper 36, the rotating grinding wheel frame 1 is rotatably connected to the inside of the fixed ring 31, the maintenance opening groove 35 is opened on the outer wall of the fixed ring 31, and the maintenance opening groove 35 is opposite to the outer end of the fixed shaft 15, and the sliding stopper 36 is slidably connected to the inside of the maintenance opening groove 35.

[0028] The rotating grinding wheel frame 1 includes a rotating frame body 11 , a slot 12 and a cylindrical feed pipe 13 . The cylindrical feed pipe 13 is integrally formed in the middle of the rotating frame body 11 , and the slot 12 is opened at the top of the rotating frame body 11 .

[0029] The fixed bracket 3 also includes a support tube 32 and a connecting arm 33. The connecting arm 33 is fixedly connected between the fixing ring 31 and the support tube 32. The cylindrical discharge tube 13 is rotatably connected to the inside of the support tube 32. The rotating frame body 11 is rotatably connected to the inside of the fixing ring 31. The outer wall of the support tube 32 is threadedly connected with a fixing screw 34. The end of the fixing screw 34 is movably inserted into the outer wall of the cylindrical discharge tube 13. The grinding block 2 is movably inserted into the inside of the slot 12. The top outer wall of the rotating frame body 11 is fixedly welded with a rotating handle 14.

[0030] By unscrewing the fixing screw 34 outward, the rotating grinding wheel frame 1 and the fixed bracket 3 can rotate relative to each other. At this time, the sliding stopper 36 is pushed to one side, and the rotating frame body 11 is rotated by rotating the handle 14 so that the grinding block 2 to be replaced is facing the inspection opening slot 35. At this time, the fixed shaft 15 is pulled out from the inspection opening slot 35, and then the corresponding grinding block 2 is lifted up and taken out, which makes it convenient to replace the damaged grinding block 2 separately, reduces the replacement cost, and ensures that the entire rotating grinding wheel frame 1 has a good grinding effect when used.

[0031] Multiple groups of grinding blocks 2 are provided with discharge gaps 4, and the discharge gaps 4 are connected to the top of the cylindrical discharge pipe 13. The crushed materials generated during grinding can fall into the cylindrical discharge pipe 13 through the discharge gaps 4 and be discharged outward.

[0032] The sliding stopper 36 includes an arc-shaped stopper 361, a holder 362, and a threaded pin 363. The arc-shaped stopper 361 is slidably disposed in the inner wall of one side of the inspection opening slot 35. The holder 362 is integrally formed at the end of the arc-shaped stopper 361. The threaded pin 363 is threadedly connected to the interior of the holder 362. A spring 364 is provided in the inner wall of one side of the inspection opening slot 35, and the end of the spring 364 abuts against the end of the arc-shaped stopper 361. The holder 362 is movably sleeved on the outer wall of one side of the inspection opening slot 35, and the end of the threaded pin 363 is movably inserted into the outer surface of one side of the inspection opening slot 35.

[0033] Push the holder 362 toward the side close to the spring 364, so that the arc baffle 361 shrinks into the inside of the fixing ring 31. At this time, the spring 364 is compressed, and then the threaded pin 363 is screwed into the outer wall of the fixing ring 31 to fix it. At this time, it is convenient to take out the fixed shaft 15. After use, unscrew the threaded pin 363 from the outer wall of the fixing ring 31. At this time, under the action of the spring 364, the arc baffle 361 can effectively block the outer wall of the rotating frame body 11 to prevent any fixed shaft 15 from slipping outward.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
