Description

Technical Field

[0001] This utility model relates to the field of chute lining technology, and in particular to a ore unloading chute lining assembly. Background Technology

[0002] A sluice is a channel set on the ground to transport things from a high place to a low place. The inner surface of the sluice is smooth, and the things can slide down automatically. An unloading sluice refers to a sluice used in open mines to transport materials such as ore. Unloading sluices usually have wear-resistant steel plates pre-embedded around the inner walls as wear-resistant materials. After long-term use, the wear-resistant steel plates will be deformed by impact and completely worn, which will then damage the concrete structure.

[0003] To improve the wear resistance of the chute, a wear-resistant steel plate is welded on the outside of the pre-embedded steel plate as a protective liner. After long-term use, the wear-resistant steel plate will be deformed by impact and completely worn. When replacing the wear-resistant plate, it is necessary to use flame cutting to remove the damaged wear-resistant steel plate and then re-weld a new wear-resistant liner, which is time-consuming and labor-intensive, making the liner replacement difficult.
