The bottom surfaces of the first and second grinding discs are flush with the bottom of the moving wheel.

[0006] Preferably, there are three No. 2 grinding discs arranged in a ring, with the No. 1 grinding disc as the center. A driving structure is provided between the No. 1 grinding disc and the No. 2 grinding disc and the base. The driving structure drives the rotation of the No. 1 grinding disc and the No. 2 grinding disc simultaneously through a motor.

[0007] Using the above technical solution, the first and second grinding discs can be rotated simultaneously by utilizing the drive structure.

[0008] Preferably, the drive structure includes a central gear, which is fixedly connected to the rotating shaft of the first grinding disc. Three external gears are arranged in a ring on the outer surface of the central gear, and the three external gears are respectively fixedly connected to the rotating shafts of the three second grinding discs.

[0009] By adopting the above technical solution, the synchronous rotation of the No. 1 and No. 2 grinding discs can be achieved by utilizing the meshing between the middle gear and the external gear.

[0010] Preferably, the three external gears mesh with the intermediate gear, and the outer surfaces of the three external gears are provided with fixing rings. The inner surfaces of the fixing rings are provided with tooth blocks, and the tooth blocks on the inner surfaces of the fixing rings mesh with the surfaces of the three external gears respectively.

[0011] Using the above technical solution, the rotation of the middle gear driven by the motor can drive the movement of the external gear.

[0012] Preferably, the base is a hollow structure, and a protective cover is fixedly installed on the lower surface of the base. The protective cover is a cylindrical structure that runs vertically through the base and is wrapped around the outer surface of the fixing ring.

[0013] By adopting the above technical solution, the polishing process can be shielded and protected using a protective cover.

[0014] Preferably, the upper surface of the base is provided with a spray structure, which sprays water through nozzles to enhance the polishing effect.

[0015] By adopting the above technical solution, the grinding disc can be cooled by water flow through the spray structure.

[0016] Preferably, the spray structure includes a water storage tank, which is fixedly installed on the upper surface of the base. A water pump is fixedly installed on the upper surface of the base.

[0030] Please see Figures 1-6 This utility model provides a technical solution: a terrazzo machine for ultra-large area, high flatness and wear-resistant concrete flooring, including a base 1, moving wheels 2, handle 3, power supply box 4, first grinding disc 5, second grinding disc 6, middle gear 7, external gear 8, fixing ring 9, connecting block 10, motor 11, protective cover 12, water storage tank 13, water pump 14, connecting pipe 15, conveying pipe 16, and nozzle 17.

[0031] The lower surface of the base 1 is provided with a moving wheel 2, the upper surface of the base 1 is fixedly installed with a handle 3, the surface of the handle 3 is fixedly installed with a power box 4, the inside of the power box 4 is equipped with a battery, and a double-layer grinding structure is provided below the base 1. The double-layer grinding structure realizes the large-area grinding process of the concrete floor through the first grinding disc 5 and the second grinding disc 6.

The bottom surfaces of the first grinding disc 5 and the second grinding disc 6 are flush with the bottom of the moving wheel 2.

[0032] like Figure 1 and Figure 2 As shown, during the process of grinding a concrete floor using this device, the user holds the handle 3 and uses the moving wheels 2 to move the base 1 on the concrete floor. The battery inside the power box 4 provides power to the device during its movement, thereby driving the first grinding disc 5 and the second grinding disc 6 to achieve a large-area grinding process on the concrete floor.

[0033] Three No. 2 grinding discs 6 are arranged in a ring around the No. 1 grinding disc 5. A driving structure is provided between the No. 1 grinding disc 5 and the No. 2 grinding discs 6 and the base 1. The driving structure, via a motor 11, simultaneously drives the rotation of the No. 1 grinding disc 5 and the No. 2 grinding discs 6. The driving structure includes a central gear 7, which is fixedly connected to the rotating shaft of the No. 1 grinding disc 5. Three external gears 8 are arranged in a ring on the outer surface of the central gear 7. Each of the three external gears 8 is fixedly connected to the rotating shaft of one of the three No. 2 grinding discs 6, and meshes with the central gear 7. The outer surfaces of the three external gears 8 are... A fixing ring 9 is provided, and a toothed block is provided on the inner surface of the fixing ring 9. The toothed block on the inner surface of the fixing ring 9 meshes with the surfaces of three external gears 8 respectively. The fixing ring 9 is fixedly installed on the lower surface of the base 1. The rotating shafts of the three external gears 8 are rotatably connected to the surface of the same connecting block 10. The connecting block 10 is rotatably installed on the lower surface of the base 1. A circular through hole is provided through the surface of the connecting block 10. A motor 11 is fixedly installed on the upper surface of the base 1. The output end of the motor 11 passes through the circular through hole on the surface of the connecting block 10 and is fixedly connected to the middle gear 7. The motor 11 is connected to the power supply box 4 through a wire.

[0034] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, during the grinding process, the motor 11 is started, which drives the central gear 7 to rotate. The rotating central gear 7 drives the three external gears 8 to rotate. Since the three external gears 8 mesh with the tooth blocks on the inner surface of the fixed ring 9 respectively, and the three external gears 8 are rotatably connected to the surface of the same connecting block 10, and the fixed ring 9 is fixedly installed on the lower surface of the base 1, the three external gears 8 will revolve synchronously along the inner surface of the fixed ring 9 while the external gears 8 rotate.

The synchronously rotating first grinding disc 5 and second grinding disc 6 perform a uniform grinding process on the concrete floor.

[0035] The base 1 has a hollow structure. A protective cover 12 is fixedly installed on the lower surface of the base 1. The protective cover 12 is a cylindrical structure that runs vertically through the base. The protective cover 12 is wrapped around the outer surface of the fixing ring 9. A spray structure is set on the upper surface of the base 1. The spray structure sprays water through the nozzle 17 to enhance the polishing effect.

[0036] like Figure 1 , Figure 3 and Figure 5 As shown, during the grinding operation, the water pump 14 is started to pump water from the water storage tank 13 into the connecting pipe 15. The water flows along the connecting pipe 15 to the delivery pipe 16 and finally enters the nozzle 17. The nozzle 17 is started, so that water is sprayed out from the nozzle 17, forming spray water on the inner surface of the protective cover 12. The spray water falls on the rotating surfaces of the first grinding disc 5 and the second grinding disc 6, cooling the first grinding disc 5 and the second grinding disc 6. The spray water finally falls on the concrete ground being ground, cooling and lubricating the ground, reducing the heat and wear generated by friction. At the same time, the external protective cover 12 intercepts the flying debris during the rotation of the first grinding disc 5 and the second grinding disc 6, preventing a large amount of debris from flying outward during the grinding process and affecting the grinding efficiency.

The motor 11 is started, and the motor 11 drives the middle gear 7 to rotate. The rotation of the middle gear 7 drives the outer gear 8 to rotate. The middle gear 7 drives the first grinding disc 5 to rotate, and the outer gear 8 drives the second grinding disc 6 to rotate, so as to evenly grind the concrete floor. The water pump 14 is started, and the water pump 14 sends the water in the water tank 13 into the delivery pipe 16 through the connecting pipe 15, and finally sprays it out from the nozzle 17 to cool and lubricate the first grinding disc 5 and the second grinding disc 6, reduce the heat generated during the grinding process, improve the grinding efficiency, and increase the overall practicality.
