[0002] During the casting process, defects such as burrs, unevenness, grooves, or hard spots may appear on the surface of steel castings. These defects not only affect the appearance of the castings but may also reduce their performance and lifespan. Grinding can remove these defects, making the casting surface smoother and flatter, thereby improving its precision and surface quality.

More importantly, during the long-term high-intensity friction operation with the steel casting, the grinding head often accumulates a large amount of heat due to frictional heat. This phenomenon not only accelerates the wear of the grinding head and frequently requires replacement, thereby increasing maintenance costs; at the same time, the debris generated during the grinding process is scattered everywhere, causing serious air pollution to the environment, potentially threatening the safety of operators, and causing a lot of inconvenience in subsequent cleanup and collection work.

The transmission roller 2023 drives the conveyor belt 2024 to move, and the conveyor belt 2024 drives the grinding belt 2025 to move, so that the rough grinding belt pre-grinds the steel casting workpiece 300. When the rough grinding position needs to be adjusted, the first drive motor 2011 drives the transmission screw 2013 to rotate, and the transmission screw 2013 and the transmission nut 2014 are threadedly transmitted, so that the transmission nut 2014 drives the movable frame 2017 to move, and the movable frame 2017 drives the crawler type flattening assembly 202 and the cleaning assembly 104 to move, thereby performing grinding operations on different positions of the cast steel workpiece 300. After rough grinding, fine grinding is then performed by the fine grinding belt; When cooling down during grinding, the liquid inside the water tank structure 1041 is extracted through the water pump equipment 1042, and the liquid enters the one-way water head structure 1043 and the multi-directional water head structure 1045 through the water pipe 1047 and the diversion delivery pipe 1044, and the liquid is discharged through the one-way water head structure 1043 and the multi-directional drainage part, so that the grinding belt 2025 can be cooled and cleaned during the grinding process. At the same time, the grinding belt 2025 can be cleaned by the cleaning brush 2042 during movement, and the cleaned waste enters the collection frame 102 below for collection. Secondly, the water tank structure 1041 also follows the movement of the crawler grinding assembly 202, so that the water tank structure 1041 can move on the pulley guide rail 105 through the movable pulley 1046, and the cleaning brush 1048 follows the movement of the water tank structure 1041 to clean the pulley guide rail 105.

[0029] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
