[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution: a wear-resistant part of a crusher with good wear resistance, including a wear-resistant block main body 1. A connecting block 2 is fixedly connected to the rear side of the top of the wear-resistant block main body 1. A fixing hole 3 is opened at the top of the front surface of the connecting block 2. A high-strength layer 4 is arranged on the outer surface of the wear-resistant block main body 1. An impact-resistant layer 5 is arranged on the outer surface of the high-strength layer 4. An anti-wear layer 6 is arranged on the outer surface of the impact-resistant layer 5. The wear-resistant block main body 1 and the connecting block 2 are of an integral structure.

[0025] In this embodiment, through the carbon fiber composite material layer 62, where the carbon fiber composite material is formed by a series of heat treatments of organic fibers and is an inorganic high-performance fiber with a carbon content higher than 90%. It is a new material with excellent mechanical properties. The carbon fiber composite material is mainly a special fiber composed of carbon elements, and its carbon content varies with different types, generally above 90%. Carbon fiber has the characteristics of general carbon materials, such as high temperature resistance, friction resistance, electrical conductivity, thermal conductivity, and corrosion resistance. Embodiment 2

[0026] Please refer to Figures 1-4As shown in the figure, on the basis of the first embodiment, the present utility model provides a technical solution: the high-strength layer 4 includes a ductile iron layer 41, and a manganese steel layer 42 is provided on the outer surface of the ductile iron layer 41. The impact-resistant layer 5 includes a nickel steel layer 51, and a chromium steel layer 52 is provided on the outer surface of the nickel steel layer 51. The wear-resistant layer 6 includes a ceramic composite layer 61, and a carbon fiber composite layer 62 is provided on the outer surface of the ceramic composite layer.

[0027] In this embodiment: through the chromium steel layer 52, where chromium steel refers to alloy steel containing chromium. Chromium can increase the hardenability of steel, improve the strength and wear resistance of steel. However, chromium steel also has a tendency to overheat and produce temper brittleness. Chromium steel is prone to white spots after forging. Low-carbon chromium steel has a relatively high surface carbon concentration and is brittle after carburization. It is a good steel for carburization. Containing chromium can increase the hardenability of steel, reduce deformation during quenching, and is beneficial to improving the strength of the core of carburized parts without reducing the impact toughness. The cold deformation plasticity of the steel is high, the weldability is good, and the machinability is best in the annealed state.
