As shown in fig. 8, the grinding disc mechanism 3 is composed of a friction disc 45 and an annular friction disc 43, as shown in fig. 11 and 15, the friction disc 45 is fixedly mounted at the lower end of the second rotating shaft 40 through a second mounting disc 44, the second mounting disc 44 and the second rotating shaft 40 are fixedly connected through a hollow fastening screw 54, and the friction disc 45 is fixedly mounted at the lower side of the second mounting disc 44; as shown in fig. 8 and 12, the annular friction plate 43 is rotatably mounted on the lower side of the housing 1 through a first mounting plate 42, as shown in fig. 13, the upper end of the first mounting plate 42 is provided with a telescopic drum 41, as shown in fig. 12, the inner side of the telescopic drum 41 is provided with a return spring 46; as shown in fig. 12, a first mounting plate 42 is rotatably mounted on the lower side of the housing 1 via a telescopic drum 41; the annular friction plate 43 is fixedly arranged at the lower side of the first mounting plate 42, and the annular friction plate 43 is positioned at the outer side of the friction plate 45; as shown in fig. 8, a transmission adjusting mechanism 5 is installed between the second rotating shaft 40 and the telescopic drum 41, and the transmission adjusting mechanism 5 performs transmission connection between the second rotating shaft 40 and the telescopic drum 41 on one hand, and controls the transmission adjusting mechanism 5 to adjust and control the rotation speed difference between the second rotating shaft 40 and the telescopic drum 41 on the other hand.

The annular friction plates 43 and the friction plates 45 are fixed with the first mounting plate 42 and the second mounting plate 44 by the prior art, such as adhesion.

The friction disc mechanism designed by the invention consists of an inner part and an outer part, and the design reason is that under the condition that the water flow is not changed, the rotating speed of the outer ring annular friction disc 43 is reduced, the speed of the sewage flying out from the lower side of the grinding disc mechanism 3 is reduced, and the area of the peripheral area polluted by the sewage is reduced; on one hand, the surrounding environment is protected, and on the other hand, the sewage can be prevented from splashing on the clothes of workers to dirty the clothes.

In the invention, because the rotation speed of the middle friction disc 45 is higher, the main part for polishing the smoother stone is the middle friction disc 45, water left in the second rotating shaft 40 flies out under the centrifugal action through the middle friction disc 45 and then contacts with the outer annular friction disc 43, and the distance of the water flying out through the outer annular friction disc 43 in a centrifugal way is relatively smaller because the rotation speed of the annular friction disc 43 is smaller, so that the outer dirty annular area of the polisher is relatively smaller.

The invention designs that the rotating speed of the annular friction plate 43 is divided into two different speeds, one is slower than that of the friction disc 45, and the other is basically equal to that of the friction disc 45, so that the design aims to reduce sewage splashing by the slower rotating speed when the relatively smooth stone is polished; can prevent through the speed that equals basically that when polishing to the great stone material of roughness, the granule of polishing down is more relatively, prevents through high-speed annular friction disc 43 this moment that the granule from piling up, fish tail stone material surface, influences the normal of mill mechanism 3 and polishes.

The reason why the annular friction plate 43 designed by the invention is installed through the telescopic rotary drum 41 is that the annular friction plate 43 is positioned at the lower side of the friction disc 45 when the telescopic rotary drum is not in operation, when the telescopic rotary drum is in operation, the annular friction plate 43 is extruded by stone to move upwards to be flush with the lower surface of the friction disc 45, and at the moment, because the annular friction plate 43 moves upwards by a certain amount, the return spring 46 is extruded to have certain compression force, and in the operation process, the compression force of the return spring 46 can be transmitted to the annular friction disc 45 to increase the pressure between the annular friction plate 43 and the bottom surface, so that the resistance of the flying-out of sewage from the lower side of.

In the invention, after entering from the water filling port 2, water firstly flows into the first liquid flow channel 14, the water flowing into the first liquid flow channel 14 passes through the second liquid flow channel 15, and the outlet of the second liquid flow channel 15 is over against the partition plate 16 between the water flow channel 8 and the air flow channel 7, so that the design aims to ensure that when the water flows out through the second liquid flow channel 15, part of water can flow into the air flow channel 7 from the round hole formed on the partition plate 16 and is taken away by the flowing gas; the remaining liquid flowing out of the second liquid passage flows into the second rotary shaft 40 through the third liquid flow passage 18 and flows out of the lower end of the second rotary shaft 40.
