The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.

[0020] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0021] It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0022] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0023] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0024] See also Figure 1-4 The utility model provides a technical solution: a rectangular alloy wear-resistant tooth plate, including a jaw plate body 1, a jaw plate tooth 2 is fixedly connected to the top of the jaw plate body 1, a high-strength layer 3 is arranged on the surface of the jaw plate body 1, a toughness layer 4 is arranged on the outer surface of the high-strength layer 3, and an anti-wear layer 5 is arranged on the outer surface of the toughness layer 4. The material of the jaw plate body 1 is the same as that of the jaw plate tooth 2, and the thickness of the high-strength layer 3, the toughness layer 4 and the anti-wear layer 5 are the same.

[0025] In this embodiment, a high carbon steel layer 7 is used, wherein the high carbon steel has high strength and hardness, high elastic limit and fatigue limit after proper heat treatment or cold drawing hardening, and acceptable cutting performance, but poor welding performance and cold plastic deformation capacity. Due to its high carbon content, cracks are easily generated during water quenching, so double liquid quenching is often used, and oil quenching is often used for small-section parts. This type of steel is generally tempered or normalized at medium temperature after quenching or used in a surface quenching state, and is mainly used to manufacture springs and wear-resistant parts. Example

[0026] See also Figure 1-4As shown, on the basis of embodiment 1, the utility model provides a technical solution: the high-strength layer 3 includes a silicon steel layer 6, the outer surface of the silicon steel layer 6 is provided with a high-carbon steel layer 7, the thickness of the high-carbon steel layer 7 is the same as the thickness of the tungsten steel layer 10, the toughness layer 4 includes a vanadium steel layer 8, the outer surface of the vanadium steel layer 8 is provided with a nickel steel layer 9, the thickness of the nickel steel layer 9 is the same as the thickness of the vanadium steel layer 8, the anti-wear layer 5 includes a tungsten steel layer 10, the outer surface of the tungsten steel layer 10 is provided with a high manganese steel layer 11, and the outer surface of the high manganese steel layer 11 is provided with a ceramic particle layer 12.

[0027] In this embodiment: through the high manganese steel layer 11, wherein the cast structure of the high manganese steel is usually composed of austenite, carbide and pearlite, and sometimes contains a small amount of phosphorus eutectic. When the number of carbides is large, they often appear in a network on the grain boundary. Therefore, the high manganese steel with the cast structure is very brittle and cannot be used. It needs to be solution treated. The commonly used heat treatment method is solution treatment, that is, the steel is heated to 1050-1100°C, and the cast structure is eliminated by insulation to obtain a single-phase austenite structure, and then water quenching is performed to keep this structure at room temperature. After heat treatment, the strength, plasticity and toughness of the steel are greatly improved.
