[0002] A loader is a kind of earth-moving machinery widely used in earthwork and mining projects. During the operation, the shovel teeth are the key components that are in direct contact with the soil or materials, and their wear directly affects the operating efficiency of the whole machine. Therefore, timely repair and replacement of the loader shovel teeth is an important link to ensure its continued efficient operation. During the application of the existing loader shovel tooth grinding device, due to the displacement between the workpiece and the grinding tool, the grinding part cannot be accurately positioned when re-grinding multiple times, which affects the work efficiency and effect to a certain extent. Therefore, it is particularly important to develop a loader shovel tooth grinding device that can adapt to this complex environment and solve the above problems. Utility Model Content

Since the sliding adjustment structure between the sliding well and the shovel tooth clamping plate is stable, the grinding of the same part is stable and accurate for multiple times; the existing loader shovel tooth grinding device solves the problem that the grinding part cannot be accurately positioned when it is repeatedly polished because displacement occurs between the workpiece and the grinder during the repeated grinding steps of the same part.

[0005] Preferably, the shovel teeth are clamped downward by locking bolts on the shovel tooth clamping plate in the positioning lifting assembly, and then the shovel tooth clamping plate is held by hand and moved downward along the sliding well, so that the lower part of the shovel tooth is ground and polished by the high-speed rotating grinding belt. Since the sliding adjustment structure between the sliding well and the shovel tooth clamping plate is stable, the grinding of the same part is stable and accurate for multiple times, which solves the problem of the existing loader shovel tooth grinding device that during the repeated grinding steps of the same part, displacement will occur between the workpiece and the grinder, resulting in the grinding part not being able to be accurately positioned when it is re-grinded for multiple times.

[0006] Preferably, the grinding assembly includes a grinder bracket, a grinding drive motor, a grinding belt, a tension adjustment roller, a fixed roller, and a spring; a grinding drive motor is arranged inside the grinder bracket, and the outer shell of the grinding drive motor is fixedly connected to the inner wall of the grinder bracket; a grinding belt is arranged above the grinding drive motor, and the grinding belt is connected to the output end of the grinding drive motor by belt drive.
