[0047] The size of wear-resistant disc 10 and reinforcing member 20 can be adjusted according to actual conditions, specifically, not too much limit here.

[0048] In the embodiment, the wear plate 10 can be made of ultra-high molecular polyethylene particles or toughened POM particles, and is formed by one-step molding through a mold injection process or is made into a plate through a mold pressing process and then is processed into a required size according to actual conditions.

[0049] In the embodiment, the reinforcing member 20 can be made of high-strength metal materials such as steel, galvanized steel or alloy steel. Such materials have good strength and wear resistance, can withstand large forces and wear, and thus effectively enhance the service life and reliability of the wear plate 10.

[0050] In some embodiments, as shown in Figure 1 the reinforcing member 20 and the wear plate 10 are formed into an integrated structure through an injection molding process.

[0051] In the production process of the wear plate 10, the reinforcing member 20 is placed at a predetermined position of an injection mold; then, a wear-resistant material is heated to a molten state and injected into the mold, so that the reinforcing member 20 is completely wrapped; after the material is cooled and solidified, the reinforcing member 20 and the wear plate 10 are tightly combined into an integrated structure. The reinforcing member 20 and the wear plate 10 are combined through the injection molding process to form a high-strength integrated structure, so that the load distribution is more uniform, local stress concentration is avoided, the service life of the wear plate 10 can be prolonged, and the stability of the overall structure is improved.

[0053] In some embodiments, the shape of the reinforcing member 20 is one of a circle, a square or a polygon, and the shape of the reinforcing member 20 can be adjusted according to actual conditions, which is not limited here.

[0054] In some embodiments, as shown in Figure 3 and Figure 4 the reinforcing member 20 is detachably connected to the wear plate 10 through a connecting assembly 30, and the connecting assembly 30 is a rivet.

[0055] The center of the wear plate 10 is provided with a plurality of fixing holes 13 arranged at equal intervals in a circle, and the plurality of fixing holes 13 are arranged at equal intervals in a circle around the traction hole 11.

In this way, the reinforcing member 20 can be conveniently installed after the wear plate 10 is formed, and the arrangement of the double-sided reinforcing member 20 further enhances the load-bearing capacity of the traction hole 11.

[0059] In other embodiments, the connecting assembly 30 can also be a bolt and a nut. Specifically, fixing holes 13 and first through holes 22 are arranged on the wear plate 10 and the two reinforcing members 20 at corresponding positions. In order to avoid the protrusion of the bolt head, a receiving groove is arranged on the corresponding first through hole 22. Then, the reinforcing member 20 is arranged on the upper and lower sides of the wear plate 10 and aligned with the holes. Finally, the bolt is inserted through the aligned holes, the bolt head is embedded in the receiving groove, and the nut is installed on the other end of the bolt. The reinforcing member 20 is firmly connected with the wear plate 10 by tightening the nut, so as to realize the detachable fixing structure.

[0060] In some embodiments, as shown in Figure 5 and Figure 6 , a lower groove 14 is arranged in the center of the wear plate 10, and the lower groove 14 is coaxially arranged with the traction hole 11 and is in communication with the traction hole 11.

[0061] A plurality of second through holes 23 are equidistantly arranged on the reinforcing member 20, and the reinforcing member 20 is fixed in the lower groove 14 by an adhesive.

Then, the reinforcing member 20 is aligned with the lower groove 14, and the steel sheet glue is evenly distributed and filled into the second through hole 23 by gently pressing. Finally, pressure is applied to the wear plate 10, and the wear plate 10 is placed in a suitable environment for curing treatment, so that the adhesive is completely cured, thereby realizing the firm adhesion of the reinforcing member 20 and the wear plate 10.

[0063] In addition, the lower groove 14 has another function of facilitating ventilation and cooling of the wear plate 10 through the lower groove 14 in hot summer, thereby playing a role in resisting deformation and reducing wear.

[0066] In some embodiments, as shown in Figure 2 The surface of the wear-resistant disc 10 is provided with a flow guide assembly 12, which includes:

[0067] The first annular groove 121 and the second annular groove 122 are arranged concentrically, and the diameter of the second annular groove 122 is greater than that of the first annular groove 121;

[0068] A plurality of radial grooves 123 are circumferentially equidistantly arranged on the upper surface of the wear-resistant disc 10, the inner end of the radial groove 123 extends to the outer edge of the reinforcing member 20, and the outer end of the radial groove 123 extends to the surface edge of the wear-resistant disc 10, and the radial groove 123 communicates with the first annular groove 121 and the second annular groove 122.

[0069] Through the concentric arrangement of the first annular groove 121 and the second annular groove 122 and the radial groove 123, the lubricating oil or grease can penetrate along the preset path to the contact surface, avoiding the lubrication dead angle. At the same time, the design that the radial groove 123 extends to the outer edge of the reinforcing member 20 ensures that the lubricating medium can act on the area of the traction hole 11, further reducing the friction resistance and the wear rate, and prolonging the service life of the wear-resistant disc 10.

[0072] In some embodiments, the cross-sectional shape of the first annular groove 121, the second annular groove 122 and the radial groove 123 is one of V-shaped, U-shaped or rectangular. The cross-sectional shape of the first annular groove 121, the second annular groove 122 and the radial groove 123 can be selected according to the viscosity, flowability and working condition of the lubricating medium. For example, the V-shaped cross-section is suitable for low-viscosity lubricating oil and can form a thinner oil film; the U-shaped and rectangular cross-sections are suitable for high-viscosity lubricating grease and can provide better adhesion. This design optimizes the interaction between the lubricating medium and the groove, further prolonging the service life of the wear-resistant disc 10.
