The purpose of this design is that when grinding relatively smooth stone, it is hoped that the slower rotation speed will reduce the splash of sewage; the basically equal speed can prevent the roughness of the stone. During grinding, there are relatively many particles under grinding. At this time, the high-speed annular friction disc is used to prevent the accumulation of particles and scratch the surface of the stone, which affects the normal grinding of the grinding disc mechanism.

3. The reason why the annular friction plate designed by the present invention is installed through the telescopic drum is that when it is not working, the annular friction plate is located on the lower side of the friction plate. The surface is flush. At this time, because the annular friction plate moves up a certain amount, the return spring is squeezed and has a certain compressive force. During the working process, the compression force of the return spring will be transmitted to the annular friction plate, increasing the annular friction plate and the bottom surface. The pressure between them increases the resistance of sewage flying out from the lower side of the annular friction disc to a certain extent, and plays a role in retaining water.

4. In the present invention, a V-shaped groove is designed on the bottom surface of the annular friction plate to ensure that the sewage splashed from the lower side of the friction disc can flow out through the V-shaped groove to prevent the accumulation of sewage; At the same time, a baffle is designed in the V-shaped groove, which can hinder the sewage flowing out through the V-shaped groove and reduce the speed of sewage flying out.

As shown in Figure 5, the rear end of the casing 1 has a handle 28. The front end of the housing 1 has a water injection port 2, and the housing 1 is provided with evenly distributed air inlet holes 27 and exhaust holes 26; as shown in Figures 2 and 3, the motor 6 is installed in the housing 1 and is located in the The rear end of the housing 1; as shown in FIG. 7, the fan 10 is fixedly installed on the output shaft of the motor 6, and is located in the housing 1; as shown in FIG. The lower side of the front end of the body 1; the second rotating shaft 40 is a hollow structure and is connected to the water injection port 2; the second rotating shaft 40 is connected with the output shaft of the motor 6 through gears; The side of the front end of the casing 1 is detachably installed with an auxiliary handle 4; It is characterized in that: as shown in Figure 5, the housing 1 has a motor installation slot 25. As shown in Figures 4 and 6, the inner circular surface of the motor installation slot 25 is uniformly installed with a plurality of pairs. The motor 6 plays a supporting and fixing role of the fixing strip 12; in the present invention, the fixing strip 12 plays a supporting role for the motor 6, so that a sufficient gap is left between the housing of the motor 6 and the motor installation slot 25 to ensure the normal circulation of the inhaled gas ; As shown in Figures 5 and 6, the air inlet holes 27 are evenly distributed on the rear end surface of the motor installation slot 25 in the circumferential direction, and the air inlet holes 27 are communicated with the outside world, and the rear end face of the motor installation slot 25 is opened into The front side of the air hole 27 is fixedly installed with an annular filter plate 9; the annular filter plate 9 has a filtering effect on the inhaled gas; the front side of the motor installation slot 25 is provided with a circular hole 76 through which the output shaft of the motor 6 passes. A second installation slot 23 is opened on the front side of the hole 76. As shown in Figures 2 and 3, the fan 10 is located in the second installation slot 23; the fan 10 works to inhale, so that there is always gas in the motor installation slot 25 during operation flow, to dissipate heat to the motor 6; the front end surface of the second installation slot 23 is provided with an air flow channel 7; as shown in FIG. The annular flow channel 30 is communicated with the end of the airflow channel 7 away from the second installation groove 23, and the exhaust holes 26 are evenly distributed on the outer surface of the rear end of the annular flow channel 30, and the exhaust holes 26 are evenly distributed in the circumferential direction. The air hole 26 communicates with the outside world; as shown in Figures 5 and 6, a water flow channel 8 is opened on the upper side of the front end of the housing 1, one end of the water flow channel 8 is communicated with the water injection port 2, and the other end of the water flow channel 8 is connected to the water flow channel 8. The upper end of the second rotating shaft 40 is connected by a connecting sleeve 38 ; a partition plate 16 with a circular hole is provided between the water flow channel 8 and the air flow channel 7 .

In the present invention, the gas inhaled through the air inlet 27 opened on the motor installation groove 25 is discharged from the air flow channel 7 after passing through the second installation groove 23; A part of the water enters the airflow channel 7 from the circular hole on the baffle 16, and the water entering the airflow channel 7 is driven by the gas entering the airflow channel 7 to flow into the annular flow channel 30 in the form of water vapor, which enhances the flow into the annular flow channel. The heat absorption capacity of the gas in 30 has a heat dissipation effect on the interlayer between the annular flow channel 30 and the motor installation groove 25, so that the groove wall of the motor installation groove 25 is at a lower temperature, which increases the radiation heat exchange of the motor 6. ; The auxiliary heat exchange is matched with the original convection heat exchange, which improves the heat dissipation effect of the motor 6, especially in summer.

The purpose of designing the connecting sleeve 38 in the present invention to connect the water flow channel 8 and the second rotating shaft 40 is to connect the square water flow channel 8 with the circular second rotating shaft 40 through the conversion of the connecting sleeve 38; There is a gap between the rotating shafts 40 due to the connection, and the phenomenon of water seepage occurs; the structure in the lower transmission adjustment mechanism 5 is corroded.

Part of the water entering through the above-mentioned water injection port 2 will enter the air flow channel 7 through the circular hole on the partition plate 16, and the water entering the air flow channel 7 will be driven by the gas flowing in the air flow channel 7 into the annular flow channel 30. A part of the water flows into the lower grinding disc mechanism 3 through the hollow second rotating shaft 40 .

As shown in FIG. 8 , the above-mentioned grinding disc mechanism 3 is composed of two parts, a friction disc 45 and an annular friction plate 43 . As shown in FIGS. 11 and 15 , the friction disc 45 is fixedly installed on the lower end of the second rotating shaft 40 through the second mounting disc 44 . , the second mounting plate 44 and the second rotating shaft 40 are fixedly connected by hollow fastening screws 54, and the friction plate 45 is fixedly installed on the lower side of the second mounting plate 44; as shown in Figures 8 and 12, the annular friction The sheet 43 is rotatably mounted on the lower side of the housing 1 through the first mounting plate 42. As shown in FIG. 13, a telescopic drum 41 is installed on the upper end of the first mounting plate 42. As shown in FIG. 12, the telescopic drum 41 The inner side has a return spring 46; as shown in Figure 12, the first mounting plate 42 is rotatably installed on the lower side of the housing 1 through the telescopic drum 41; the annular friction plate 43 is fixedly installed on the underside of the first mounting plate 42, and the annular friction The plate 43 is located on the outside of the friction disc 45; as shown in FIG. 8, a transmission adjustment mechanism 5 is installed between the above-mentioned second rotating shaft 40 and the telescopic rotating drum 41. The drums 41 are connected by transmission. On the other hand, the rotation speed difference between the second rotating shaft 40 and the telescopic drum 41 can be adjusted and controlled by controlling the transmission adjustment mechanism 5 .

In the present invention, the fixing of the annular friction plate 43 and the friction disc 45 to the first installation disc 42 and the second installation disc 44 adopts the prior art, such as sticking.

The friction disc mechanism designed by the present invention is composed of two parts, the inner and outer parts. The reason for this design is that, under the condition of constant water flow, by reducing the rotation speed of the outer ring friction plate 43, it can reduce the flow of sewage from the lower side of the grinding disc mechanism 3. The flying speed reduces the area of the surrounding area contaminated by sewage; on the one hand, it protects the surrounding environment, and on the other hand, it can prevent the sewage from splashing on the clothes of the workers and soiling the clothes.

In the present invention, because the rotation speed of the middle friction disc 45 is faster, the main component of the present invention for polishing the smoother stone is the middle friction disc 45, and the water left on the second rotating shaft 40 passes through the middle friction disc 45, After flying out under centrifugal action, it will come into contact with the outer annular friction plate 43, and the centrifugal flying distance of the outer annular friction plate 43 is due to the small rotation speed of the annular friction plate 43, and the dirty annular area outside the grinder Relatively small.

The rotation speed of the annular friction plate 43 designed in the present invention is divided into two different speeds, one is relatively slow relative to the friction plate 45, and the other is basically equal to the rotation speed of the friction plate 45, the purpose of this design is When the stone is relatively smooth, it is hoped that the slower rotation speed can reduce the splash of sewage; the basically equal speed can prevent the grinding of the rough stone from relatively more particles. At the same time, the high-speed annular friction plate 43 prevents particles from accumulating, scratches the surface of the stone, and affects the normal grinding of the grinding disc mechanism 3.

The reason why the annular friction plate 43 designed by the present invention is installed through the telescopic drum 41 is that the annular friction plate 43 is located on the lower side of the friction plate 45 when it is not working. The lower surface of the friction disc 45 is flush. At this time, because the annular friction plate 43 moves up a certain amount, the return spring 46 is squeezed to have a certain compressive force. During the working process, the compressive force of the return spring 46 will be transmitted to the annular friction disc. 45, increasing the pressure between the annular friction plate 43 and the bottom surface increases the resistance of sewage flying out from the lower side of the annular friction plate 45 to a certain extent, and plays a role in retaining water.

As shown in FIG. 5 , the air flow channel 7 includes a second gas flow channel 20 communicated with the second installation groove 23 , and a first gas flow channel 13 communicated with the annular flow channel 30 .

In the present invention, after the water enters from the water injection port 2, it will first flow 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 facing The partition 16 between the water flow channel 8 and the airflow channel 7 is designed to ensure that when the water flows out through the second liquid flow channel 15, a part of the water can flow into the airflow channel from the circular hole opened on the partition plate 16 7, is taken away by the flowing gas; the remaining liquid flowing out from the second liquid channel flows into the second rotating shaft 40 through the third liquid flow channel 18, and flows out from the lower end of the second rotating shaft 40.

As shown in FIG. 6 , the above-mentioned annular flow channel 30 is divided into two parts by two spacers 11 evenly distributed in the circumferential direction, and a third gas flow passes between the first gas channel and the separated two-part annular flow channel 30 respectively. Channel 7 is on.

The purpose of designing the third airflow channel 7 in the present invention is that it is hoped that the gas with moisture can be dispersed through the two third airflow channels 7, so that the gas with moisture can be evenly blown into the annular flow channel 30, The uniformity of the flow of the gas with water vapor is ensured, and the heat dissipation effect of the gas with water vapor on the motor 6 is improved.

In the present invention, a part of the gas flowing in the air flow channel 7 will enter the lower water flow channel 8 through the circular hole on the partition plate 16 , but the water flow channel 8 has water flow.
