[0027] like Figures 1 to 4 As shown, an assembled grinding disc comprises:

[0028] The disc body 101 has a plurality of screw holes 102 disposed on the top of the disc body 101. Each grinding block 2 is located below the bottom of the corresponding screw hole 102. A screw 103 is screwed into each screw hole 102 and the corresponding grinding block 2. Thus, the grinding blocks 2 are detachably arranged in a circular array at the bottom of the disc body 101. A grinding groove 201 is formed between two adjacent grinding blocks 2. A rotating shaft 104 is disposed in the middle of the disc body 101. The rotating shaft 104 can be connected to an external drive shaft to drive the disc body 101 to rotate.

[0029] Air supply holes 3, there are multiple groups of air supply holes 3, and the number is the same as the number of grinding grooves 201, each group of air supply holes 3 is located on the part of the disc 101 corresponding to the top of the grinding groove 201, and the number of air supply holes 3 in each group of air supply holes 3 is multiple;

[0030] The air distribution component is tightly sleeved on the rotating shaft 104 and is used to deliver pressurized air to each group of air supply holes 3. The air distribution component includes an air collecting sleeve 401 tightly sleeved on the rotating shaft 104. The air collecting sleeve 401 can rotate synchronously with the rotating shaft 104. An annular groove 402 is provided on the outer periphery of the upper half of the air collecting sleeve 401. A through hole 403 that penetrates the inner cavity of the air collecting sleeve 401 is provided on the side wall of the annular groove 402. The air delivery component includes an annular wind cover shell 501. The annular wind cover shell 501 is rotatably sleeved in the annular groove 402, which promotes the air collection sleeve 401 to rotate with the rotating shaft 104. During the process, the annular wind cover shell 501 may not rotate with the air collecting sleeve 401. The annular wind cover shell 501 is respectively provided with rubber pads 6 at the junctions with the groove top and the groove bottom of the annular groove 402. The provided rubber pads 6 can enhance the sealing performance of the junctions between the annular wind cover shell 501 and the groove top and the groove bottom of the annular groove 402. The annular wind cover shell 501 is provided with an air inlet pipe 502. The provided air inlet pipe 502 can be connected to an external air duct, so that pressurized air can be introduced into the annular wind cover shell 501 through the air inlet pipe 502, and the pressurized air entering the annular wind cover shell 501 can be collected into the interior of the air collecting sleeve 401 through the through hole 403;

[0031] The lower half of the air collecting sleeve 401 is provided with a plurality of air supply pipes 404 in an array on the periphery thereof. The number of the air supply pipes 404 is the same as the number of the air supply holes 3. An air cover 405 is provided at one end of each air supply pipe 404. Each air cover 405 is tightly covered on the air supply holes 3 of the corresponding group. When the pressure wind flows into the interior of the air collecting sleeve 401, the pressure wind can be sent into the corresponding air cover 405 through each air supply pipe 404, and then sprayed into the corresponding grinding groove 201 from each group of air supply holes 3. In this way, during the grinding process, the pressure wind can be blown into each grinding groove 201, so as to blow out the dirt in the grinding groove 201 and avoid the dirt residue from accumulating in the grinding groove 201.
