A fixed bearing 14 is fixedly installed on the outer surface of the rotating rod 13. The fixed bearing 14 is fixedly installed inside the control box 1. When the adjusting motor 11 is started, the rotating shaft drives the drive gear 12 to rotate. The fixed bearing 14 ensures that the rotating rod 13 rotates stably.

[0026] To facilitate adjustment of the angle of the grinding brush 23 head, a driven gear 15 is fixedly installed on the outer surface of the rotating rod 13. The outer surface of the driven gear 15 meshes with the outer surface of the driving gear 12. A swing frame 16 is fixedly installed on the outer surface of the rotating rod 13. A crossbar 17 is fixedly installed on both the left and right sides of the swing frame 16. The mounting box 2 is slidably connected to the outer surface of the crossbar 17. The driving gear 12 drives the driven gear 15 to rotate, causing the rotating rod 13 to rotate. The rotating rod 13 drives the swing frame 16 to swing, thereby adjusting the angle of the grinding brush 23 head.

[0027] To ensure that the mounting box 2 and the swing frame 16 remain in a straight line, mounting frames 21 are fixedly installed on both the left and right sides of the mounting box 2. The inner surface of the mounting frame 21 is slidably connected to the outer surface of the crossbar 17. A mounting box 18 is fixedly installed on the lower surface of the swing frame 16. A control motor 19 is fixedly installed inside the mounting box 18. A threaded rod 110 is fixedly installed on the shaft of the control motor 19. The crossbar 17 slides within the mounting frame 21 to ensure that the mounting box 2 and the swing frame 16 remain in a straight line. When the control motor 19 starts, the shaft drives the threaded rod 110 to rotate.

[0028] To facilitate control of the movement of the mounting box 2 and the rotation of the grinding brush 23, a fixing plate 6 is placed on the lower surface of the mounting box 2, with the upper surface of the fixing plate 6 in contact with the lower surface of the mounting box 2. The interior of the fixing plate 6 is threadedly connected to the outer surface of the threaded rod 110. A starter motor 22 is fixedly installed inside the mounting box 2, and the grinding brush 23 is fixedly installed on the shaft of the starter motor 22. The threaded rod 110 drives the fixing plate 6 to move, thereby moving the mounting box 2. The starter motor 22 controls the shaft to drive the grinding brush 23 to rotate.

[0029] To facilitate the stable installation of the fixing block 4 and the fixing plate 6 under the mounting box 2, the two fixing blocks 4 are respectively fixedly installed on the left and right sides of the fixing plate 6. The limiting screw 3 is threadedly connected to the inside of the fixing block 4, and the outer surface of the limiting screw 3 is threadedly connected to the inside of the mounting box 2. The limiting frame 5 is slidably connected to the outer surface of the fixing block 4. A sliding block 51 is fixedly installed on the inner surface of the limiting frame 5. The sliding block 51 is slidably inserted into the inside of the fixing block 4. A spring 52 is fixedly installed on the outer surface of the sliding block 51.

The limiting screw 3 is turned into the fixing block 4 and the mounting box 2 to stably install the fixing block 4 under the mounting box 2, so that the fixing plate 6 is installed under the mounting box 2.

[0030] By setting a limiting device, the grinding direction can be adjusted according to the working requirements when the grinding brush 23 is grinding. During adjustment, the adjusting motor 11 is started, which drives the drive gear 12 to rotate. The drive gear 12 drives the driven gear 15 to rotate, causing the rotating rod 13 to rotate. The rotating rod 13 drives the swing frame 16 to swing, thereby adjusting the angle of the grinding brush 23 head. Then, the control motor 19 is started, which drives the threaded rod 110 to rotate. The threaded rod 110 drives the fixing plate 6 to move, thereby moving the mounting box 2 and adjusting the distance between the grinding brush 23 head and the control box 1. After all adjustments are completed, the starting motor 22 is started to control the grinding brush 23 to rotate and work. When disassembling the grinding brush 23, the limiting frame 5 is moved away from the surface of the limiting screw 3, and then the limiting screw 3 is removed, so that the fixing plate 6 and the mounting box 2 are separated. This achieves the effect of conveniently adjusting the distance of the grinding brush 23 head and conveniently disassembling and assembling the grinding brush 23.

[0031] Working principle: When controlling the grinding brush 23 to perform grinding, the grinding direction is adjusted according to the working requirements. During adjustment, the adjustment motor 11 is started, which drives the drive gear 12 to rotate. The drive gear 12 drives the driven gear 15 to rotate, causing the rotating rod 13 to rotate. The rotating rod 13 drives the swing frame 16 to swing, thereby adjusting the angle of the grinding brush 23 head. The forward and reverse switch on the control box 1 can control the rotation of the rotating rod 13 back and forth. Then, the control motor 19 is started, which drives the threaded rod 110 to rotate. The threaded rod 110 drives the fixed plate 6 to move, thereby moving the mounting box 2 and adjusting the distance between the grinding brush 23 head and the control box 1. After all adjustments are completed, the starter motor 22 is started to control the grinding brush 23 to rotate and work. When disassembling the grinding brush 23, the limit frame 5 is moved away from the surface of the limit screw 3, and then the limit screw 3 is removed, so that the fixed plate 6 and the mounting box 2 are separated.
