Specifically, the wear-resistant lining plates 101 are all arc-shaped plate-shaped silicon carbide blocks, so that the wear-resistant lining plates 101 have significant wear-resistant use capabilities. In addition, the wear-resistant lining plates 101 can be circumferentially distributed in 12, 24 or 36 blocks, so that the wear-resistant lining plates 101 are circumferentially connected end to end to form the entire circumference. Then, the wear-resistant lining plates 101 are spliced to facilitate subsequent individual replacement and maintenance of the wear-resistant lining plates 101. In addition, the wear-resistant lining plates 101 can be replaced according to the actual wear degree.

As for the combination and disassembly of the wear-resistant lining plate 101 outside the wheel body wear-resistant bushing 201, one setting mode is that the wear-resistant lining plate 101 and the wheel body wear-resistant bushing 201 are detachably combined by adding the fixing piece 1031 through the mounting hole 102 to the wear-resistant bushing, and then the corresponding wear-resistant lining plate 101 can be disassembled by removing the fixing piece 1031. The combination and disassembly of the wear-resistant lining plate 101 outside the wheel body wear-resistant bushing 201 is simple and easy to implement, which facilitates the quick combination of the wear-resistant lining plate 101 outside the wheel body wear-resistant bushing 201 to extend the wear replacement cycle, and facilitates the subsequent replacement of the wear-resistant lining plate 101 after disassembling the wear-resistant lining plate 101 from the wheel body wear-resistant bushing 201.

The combination and disassembly of the wear-resistant lining plate 101 outside the wheel body wear-resistant bushing 201 is simple and easy to implement, which facilitates the quick combination of the wear-resistant lining plate 101 outside the wheel body wear-resistant bushing 201 to extend the wear replacement cycle, and facilitates the subsequent replacement of the wear-resistant lining plate 101 after disassembling the wear-resistant lining plate 101 from the wheel body wear-resistant bushing 201. Since the wear-resistant lining plate 101 is an arc plate-shaped silicon carbide block, the wear-resistant lining plate 101 has excellent wear resistance, and a plurality of wear-resistant lining plates 101 are arranged in a circumferential direction and connected in a circumferential direction to form a whole circumference, so that the wear-resistant lining plate 101 can be replaced and maintained individually, the wear-resistant lining plate 101 at a corresponding position can be replaced flexibly according to the actual wear degree, which is helpful to further extend the replacement cycle and reduce the replacement cost.
