[0042] The adjusting mechanism 5 is located at the top of the base 1. The adjusting mechanism 5 includes a fixed shell 52. The outer wall of the fixed shell 52 is fixedly connected with a connecting column 53. Both sides of the top of the base 1 are fixedly connected to the outer walls of the connecting column 53, and are symmetrically arranged along the central axis of the rotating shaft 12. The outer wall of the fixed shell 52 is slidably connected with a sliding shell 51. A semicircular plate is fixedly connected to the top of the base 1. The outer wall of the sliding shell 51 is connected to the dust collection mechanism 3 through an air pipe 55. The outer wall of the air pipe 55 is slidably connected to the outer wall of the base 1. The outer wall of the fixed shell 52 is slidably connected with a baffle 54. The outer wall of the baffle 54 is fixedly connected to the outer wall of the air pipe 55.

[0043] The outer wall of the connecting frame 11 is slidably connected to the inner wall of the fixed cylinder 10, the outer wall of the bottom of the connecting frame 11 is fixedly connected to the outer wall of the top of the grinding stone 8, the outer wall of the bottom of the grinding stone 8 contacts the outer wall of the cutting blade 9, the inner wall of the top of the base 1 is fixedly connected with a leakage box 13, and a leakage hole 14 is opened in the wall of the leakage box 13, the top of the base 1 is fixedly connected with a support frame 34, and a leakage groove 35 is opened in the wall of the support frame 34, and the outer wall of the top of the support frame 34 is fixedly connected with a fixed cover 31, and a through hole 36 is opened in the wall of the fixed cover 31. When dust falls into the leakage box 13, the vibration caused during grinding forces the dust to fall into the dust collecting box 2.

When the filter plate 33 is blocked, the end of the fixed cover 31 close to the filter plate 33 can be screwed out, and the filter plate 33 can be taken out and replaced.

[0045] The drain groove 35 is located directly below the fixed cover 31 , and the through holes 36 are arranged in a ring shape with the fixed cover 31 as the center.

[0046] Working principle:

[0047] When in use, the base 1 is placed on the ground, and the cutting disc 9 to be polished is placed on the rotating shaft 12, and a limit block is provided on the rotating shaft 12. At this time, the limit block limits the cutting disc 9 on the rotating shaft 12, and the nut is screwed into the rotating shaft 12 along the thread on the rotating shaft 12, and the cutting disc 9 is fixed. After the cutting disc 9 is fixed, the double-headed motor 4 is started, and the double-headed motor 4 is fixed to the base 1 through the frame 6. Through the rotation of the double-headed motor 4, the rotating shaft 12 is forced to rotate synchronously, and the cutting disc 9 can be forced to rotate at high speed. After the cutting disc 9 rotates, the height of the pressure rod 7 in the fixed cylinder 10 can be changed, so that the pressure rod 7 drives the connecting frame 11 to move, and the grinding stone 8 is fixed at the bottom of the connecting frame 11. Therefore, under the movement of the pressure rod 7, the grinding stone 8 is forced to move synchronously, and then the cutting disc 9 can be polished.

[0048] When the cutting blade 9 is grinding, the double-headed motor 4 drives the rotating shaft 12 to rotate, and synchronously drives the transmission shaft 37 in the dust collection mechanism 3 to rotate. The transmission shaft 37 passes through the fixed cover 31, and a blade group 32 is fixed at one end in the fixed cover 31. Therefore, the blade group 32 rotates synchronously at high speed under the drive of the transmission shaft 37, and a through hole 36 is provided on the fixed cover 31. Therefore, driven by the blade group 32, air enters the fixed cover 31 from the through hole 36, and the filter plate 33 in the fixed cover 31 will filter the dust in the air and discharge the filtered air through the holes in the filter plate 33. An exhaust groove is also provided on the fixed cover 31. Therefore, the air passing through the filter plate 33 can be discharged to the outside through the exhaust groove, and the dust blocked by the filter plate 33 will move to the base 1 through the leakage groove 35 provided on the fixed cover 31 and the support frame 34. A dust collecting box 2 is provided in the base 1. Therefore, after the dust enters the base 1, it will continue to move to the dust collecting box 2.

[0049] And the adjustment mechanism 5 located outside the cutting blade 9 can change the position of the corresponding adjustment mechanism 5 according to the cutting blade 9 of different thicknesses. By sliding the sliding shell 51 on the fixed shell 52, the position between the sliding shell 51 and the fixed shell 52 can be changed, and the fixed shell 52 is connected to the top of the base 1 through the connecting column 53. At the same time, the air pipe 55 connects the sliding shell 51 and the fixed cover 31. Therefore, when the blade group 32 rotates, the pressure difference generated forces the air in the air pipe 55 to be forced to be sucked into the fixed cover 31, so that the dust generated during grinding can be sucked into the air pipe 55, and then moved to the fixed cover 31 through the air pipe 55. A baffle 54 is fixed at one end of the air pipe 55 close to the fixed cover 31. Therefore, when the sliding shell 51 moves, the baffle 54 will block the gap exposed by the movement of the sliding shell 51 to prevent dust from leaking out.

[0050] At the same time, a leakage box 13 is fixed to the inner wall at the top of the base 1. When the cutting disc 9 is polished, the dust thrown out due to the rotation of the cutting disc 9 will move into the leakage box 13 driven by the cutting disc 9, and a leakage hole 14 is opened on the leakage box 13. The vibration generated during polishing can be used to shake the dust in the leakage box 13 into the dust collecting box 2. Liquid is provided in the dust collecting box 2. Therefore, after the dust falls into the dust collecting box 2, it mixes with the liquid to prevent the dust in the dust collecting box 2 from flying out due to the airflow of the dust suction mechanism 3.

[0051] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
