The blade is fixed on the fixing plate 25 by inserting the positioning bolt into the through hole of the blade and then screwing it into the positioning screw hole 26. The limiting screw is loosened, and the crank 7 is turned. The crank 7 drives the rotating shaft 5 to rotate, so that the active bevel gear 6 rotates, and the active bevel gear 6 drives the driven bevel gear 8 to rotate, so that the rotating drum 4 rotates, and the turntable 9 rotates, and the turntable 9 drives the L-shaped plate 13 to rotate. When the L-shaped plate 1 When the L-shaped plate 13 abuts against one side of the limit block 11, the limit block 11 is squeezed and the spring 12 is compressed. When the L-shaped plate 13 is separated from the surface of the limit block 11, the spring 12 is reset, so that the limit block 11 is reset, so that the turntable 9 is rotated 90 degrees more accurately. When the blade is rotated to the bottom of the screw guide rail 14, the electric push rod 28 works, and the electric push rod 28 drives the grinding motor 29 to move downward, so that the grinding disc 30 contacts the blade. The grinding motor 29 drives the grinding disc 30 to rotate and grinds the blade. Through the screw guide rail 14, the grinding disc 30 is driven to move, so that the grinding disc 30 fully grinds the blade. After the grinding is completed, the next blade that has not been grinded is rotated to the bottom of the grinding disc 30 for continuous grinding, thereby improving the grinding efficiency.

[0035] When grinding, the water pump 16 works to pump out the water inside the grinding box 1 through the suction pipe and discharge it to the nozzle 18 through the drainage pipe 17. The water is sprayed to the grinding disc 30 through the nozzle 18 to cool the grinding disc 30, thereby increasing the service life of the grinding disc 30. The water flows through the grid-shaped partition 3 and falls into the bottom of the grinding box 1. The debris mixed in the water flow is filtered through the filter net 20, so that the water flow is reused, saving a certain amount of water resources, and the plug plate 19 can be pulled out to clean the debris.

[0036] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
