Install the protective cover 10 on the upper end of the mounting cover 7, ensuring that the output end of the grinding motor 1 passes through the circular opening at the upper end of the mounting cover 7 and the pre-reserved hole in the protective cover 10 in sequence. Then, pass the liquid pump 8 through the limiting bracket 2 6. Use sealant or other materials to ensure that the connection is sealed and leak-proof. Install the annular pipe portion of the spray pipe 9 around the top of the grinding disc 3, and adjust the L-shaped pipe portion so that its bottom end faces the side wall of the grinding disc 3, and its position is... Connect the output end of the liquid pump 8 to the spray pipe 9 at the gap between the grinding disc 3 and the mounting cover 7, ensuring a tight connection and smooth liquid delivery. In actual use, the liquid pump 8 is connected to the water tank through a pipe. Start the grinding motor 1 to make the grinding disc 3 rotate at high speed.

[0040] Working Principle: When using this terrazzo flooring grinding device, the grinding motor 1 serves as the power source. After starting, it drives the grinding disc 3 to rotate at high speed through the connecting frame 2, performing grinding operations on the terrazzo floor. During use, the operator can adjust the height of the connecting frame 2 via the lifting column 4 according to actual grinding needs. The operator operates the lifting column 4 to smoothly raise and lower it under the guidance of limit frame 1 5 and limit frame 2 6, thereby changing the contact pressure between the grinding disc 3 and the ground to adapt to different flooring materials with varying hardness and grinding stages. When grinding begins, the liquid pump 8 starts, drawing out liquid and delivering it to the grinding area through the spray pipe 9. The annular pipe ensures that the liquid can be distributed around the grinding disc 3, while the L-shaped pipe precisely sprays the liquid onto the contact point between the grinding disc 3 and the ground, promptly cooling the high-temperature grinding disc generated by high-speed operation, reducing disc wear, and effectively suppressing dust generated during grinding, improving the working environment and enhancing grinding quality.

[0041] During grinding operations, the entire grinding device is moved by the ball bearings at the bottom of the support frame 13 and the height contact column 16. The support frame 13 is installed on the upper end of the auxiliary frame 12. The auxiliary frame 11 and the auxiliary frame 12 form a rectangular frame structure, which stabilizes the support device and facilitates movement. During the movement, the positioning frame 14 plays a role. It is slidably connected to both sides of the auxiliary frame 11 and the auxiliary frame 12. It works with the height adjustment threaded tube 15 to adjust the grinding height of the terrazzo floor. The ball bearings at the bottom of the height contact column 16 allow it to roll smoothly on the ground. When the ground height changes in the grinding area, the height contact column 16 shifts. The change triggers the warning light 17 at the upper end of the threaded tube 15, which illuminates, reminding the construction personnel to adjust the grinding operation in time to avoid uneven grinding due to abnormal ground height, ensuring the grinding effect and increasing the overall practicality.
