A mounting plate 10 is connected to one side of the driving shaft 9. A mounting sleeve 2 is connected to one side of the grinding wheel body 5, and a locking ring 4 is mounted on the outer wall of the mounting sleeve 2.

[0020] The outer wall of the sand tray 12 is evenly provided with blind teeth 6;

[0021] The length of the blind tooth 6 is set to be eight tenths of the width of the sand tray 12, and the distances between the two ends of the blind tooth 6 and the edge of the sand tray 12 are both one tenth of the width of the sand tray 12;
