[0038] like Figure 1-5As shown, a grinding device includes a frame, a enclosure 2, a rotating shaft 3, a grinding disc 4, a drive component 5, a dustproof component, and a connecting component. The frame includes support feet 11, reinforcing rods 12, screws 13, and support blocks 14. Preferably, there are four support feet 11, one end of which is fixed to the bottom of the enclosure 2. The reinforcing rods 12 connect adjacent support feet 11, and their two ends are respectively fixed to the support feet 11. The screws 13 are respectively screwed to the bottom of the support feet 11. The support blocks 14 are fixed to the ends of the screws 13. The support blocks 14 can be adjusted by rotating the screws 13, thereby leveling the frame to prevent the device from shaking during operation. The enclosure 2 has a working cavity and an opening at its top. The rotating shaft 3 is rotatably connected to the middle of the enclosure 2. The grinding disc 4 has a mounting hole in its middle and is detachably connected to the rotating shaft 3 through the connecting component. The drive component 5 is a conventional servo motor, which is fixed to the bottom of the enclosure 2, and its output shaft is fixedly connected to the rotating shaft 3.

[0039] Specifically, the connecting components include a baffle 61, a thread 62, a nut 63, a washer 64, a protective sleeve 65, and a plug-in plate 66. The baffle 61 is fixed to the rotating shaft 3; the thread 62 is formed on the upper half of the rotating shaft 3; the nut 63 can be screwed onto the rotating shaft 3; the washer 64 can be sleeved on the rotating shaft 3; the protective sleeve 65 can be sleeved on the outside of the nut 63; the plug-in plate 66 is fixed to the bottom of the protective sleeve 65, and the washer 64 has a plug-in groove 641 that mates with the plug-in plate 66. When fixing the grinding disc 4, the mounting hole of the grinding disc 4 is aligned with the rotating shaft 3 and moved downwards, so that the grinding disc 4 can be fixed. The bottom of the grinding disc 4 contacts the baffle 61. Then, the pad 64 is placed on the rotating shaft 3, and the nut 63 is screwed into the rotating shaft 3 and pressed tightly onto the pad 64, thus completing the fixation of the grinding disc 4. Next, the protective sleeve 65 is placed over the nut 63 and the plug plate 66 is inserted into the plug groove 641. This reduces the contact between water and the connection between the nut 63 and the rotating shaft 3, prevents rust at the connection, and facilitates subsequent disassembly. When the grinding disc 4 needs to be replaced, the protective sleeve 65 is removed, the nut 63 is unscrewed, and the pad 64 is removed to take out the grinding disc 4. Disassembly is very convenient.

[0040] As a preferred embodiment, a protrusion 661 is fixed on the plug plate 66, the protrusion 661 has an inclined surface, and the side wall of the plug groove 641 has a slot 642 that mates with the protrusion 661 to prevent the protective sleeve 65 from falling off automatically; a first sealing protrusion 662 is fixed on the side wall of the plug plate 66, and a first sealing groove 663 that mates with the first sealing protrusion 662 is provided on the side wall of the plug groove 641; a second sealing protrusion 651 is provided at the bottom of the protective sleeve 65, and a second sealing groove 652 that mates with the second sealing protrusion 651 is provided on the pad 64 to ensure the isolation effect of the protective sleeve 65.

[0041] Specifically, the dust suppression components include a water supply pipe 71, a spray pipe 72, a recovery pipe 73, and a nozzle 74. The water supply pipe 71 is connected to a water tank via a water pump; the spray pipe 72 is connected to the water supply pipe 71; the nozzle 74 is fixed on the spray pipe 72, so that water can be sprayed onto the grinding disc 4 through the nozzle 74 to reduce dust generation; one end of the recovery pipe 73 is fixed to the bottom of the enclosure 2 and is used to collect the waste liquid generated by water spraying for dust suppression.

[0042] As a preferred embodiment, the dustproof assembly also includes a support plate 75, a connecting shaft 76, and a drive component for reciprocating the connecting shaft 76. The support plate 75 is symmetrically fixed on the top of the enclosure 2. One end of the connecting shaft 76 is rotatably connected to the support plate 75, and the other end is fixed to the spray pipe 72. When it is necessary to grind larger stones, the drive component can drive the nozzle 74 to reciprocate, thereby spraying water evenly onto the grinding disc 4. The drive component includes a fixed rod 771, a motor 772, a first bevel gear 773, and a second bevel gear 774. Gear 774 and third bevel gear 775, one end of fixing rod 771 is fixed to the top of enclosure 2; motor 772 is fixed to the end of fixing rod 771; first bevel gear 773 is fixed to the output shaft of motor 772, half of which has teeth and half of which is toothless; second bevel gear 774 is fixed to connecting shaft 76; third bevel gear 775 is fixed to connecting shaft 76, and is correspondingly set to the second bevel gear 774. Both the second bevel gear 774 and the third bevel gear 775 can mesh with the first bevel gear 773.
