[0020] The bearing is a tapered roller bearing.

[0021] A counterweight installing device 18 is provided at the radially symmetrical position of the worm box 10 with the main motor connecting disk 1 as the center, and a counterweight block opposite to the installing position of the second motor 17 is provided on the counterweight installing device 18.

[0022] There are three driven gears 15, which are circumferentially and uniformly installed in the gear box 11. The angle between the grinding disks 12 is uniformly distributed in the gear box 11 at 120 degrees. The gear box 11 can realize the forward rotation and reverse rotation by adjusting the rotating direction of the second motor 17, so that the ground can be uniformly ground.

[0023] Working Principle:

[0024] As to auto-rotation of each grinding disk: the first motor 16 drives the driving gear 13 in the gear box 11 to rotate through the driving shaft 4. The driving gear 13 drives the intermediate gear 14 to rotate. The intermediate gear 14 drives the driven gear 15 to rotate. Finally, the grinding disk 12 installed on the shaft of the driven gear 15 rotates.

[0025] As to revolution of three grinding disks: the hollow shaft sleeve 9 provided around the driving shaft 4 does not interfere with the rotation of the driving shaft 4. The second motor 17 drives the worm 2 in the worm box 10 to rotate. The worm 2 drives the worm gear 3 to rotate. The worm gear 3 is fixedly installed at the periphery of the hollow shaft sleeve 9. The hollow shaft sleeve 9 rotates. The hollow shaft sleeve 9 is fixedly connected with the gear box 11, finally driving the gear box 11 to rotate.

[0026] The external structure of the counterweight installing device 18 can be the same as that of the worm box 10. The counterweight installing device 18 is connected with the counterweight block. The counterweight block can be used cooperatively according to the weight of the second motor 17 to balance the counterweight around the whole gear box 11.

[0027] The above are only the preferred specific embodiments of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any equivalent substitution or change made by those skilled in the art within the technical scope disclosed by the present disclosure according to the technical solution of the present disclosure and the inventive concept thereof should be covered in the scope of protection of the present disclosure.
