Bolts are prone to corrosion and are not convenient to install. Inlays are also inconvenient to install and disassemble, affecting subsequent work efficiency. There is an urgent need for a wear-resistant liner specifically for mining machinery to solve the above problems. Utility Model Content

Magnetic blocks are attached to the lower ends of the two inverted U-shaped positioning strips using epoxy resin adhesive. The liner body is located below the mounting plate and consists of a base material layer, a high-toughness transition layer, and a high-hardness wear-resistant layer. Dovetail grooves are provided on the upper left and right sides of the base material layer, and positioning grooves are provided at the front and rear ends of the two dovetail grooves.

[0007] Furthermore, the upper end of the mining machinery mounting plate is provided with multiple elliptical holes, and the mining machinery mounting plate is installed on the mining machinery by multiple bolts.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1-3 This utility model provides a wear-resistant liner for mining machinery, including a mining machinery mounting plate 1 and a liner body 13. The mining machinery mounting plate 1 has bent inner grooves 3 on its front, rear, left, and right sides. Multiple transverse reinforcing ribs 5 are horizontally welded inside the mining machinery mounting plate 1. Two dovetail strips 6 are fixed to the lower left and right sides of the mining machinery mounting plate 1 by multiple hexagonal bolts. Positioning holes 7 are provided at the connection points between the multiple bent inner grooves 3 and the upper front and rear sides of the two dovetail strips 6. The multiple positioning holes 7 are longitudinally inserted... Two inverted U-shaped positioning strips 9 are provided, and the lower ends of the two inverted U-shaped positioning strips 9 are glued with epoxy resin to the magnetic blocks 10. The liner body 13 is located below the mining machinery mounting plate 1. The liner body 13 is composed of a base material layer 14, a high-toughness transition layer 15 and a high-hardness wear-resistant layer 16. Dovetail grooves 12 are opened on the left and right sides of the upper end of the base material layer 14. Positioning grooves 11 are opened at the front and rear ends of the two dovetail grooves 12. This design solves the problems of insufficient wear resistance, short service life and inconvenient installation of traditional wear-resistant liners.

[0021] As the first embodiment of this utility model:

[0022] The upper end of the mining machinery mounting plate 1 has multiple elliptical holes 2. The mining machinery mounting plate 1 is installed on the mining machinery with multiple bolts. The added mining machinery mounting plate 1 is installed on the mining machinery with multiple bolts, and it serves as the mounting base for the liner body 13, facilitating the individual assembly and disassembly of the liner body 13. Triangular reinforcing ribs 4 are welded to the left, right, front, and rear sides of the mining machinery mounting plate 1. The lower ends of the multiple triangular reinforcing ribs 4 and multiple transverse reinforcing ribs 5 are all attached to the base material layer 14. By adding multiple triangular reinforcing ribs 4 and multiple transverse reinforcing ribs 5, the lower ends of the base material layer 14 are attached to the base material layer 14, which can concentrate the impact force of the base material layer 14 and distribute it to the entire liner, avoiding local breakage, improving the overall rigidity of the liner, and reducing the risk of deformation.

[0023] Multiple return springs 8 are longitudinally installed within the multiple bent inner grooves 3. The lower ends of the multiple return springs 8 abut against two inverted U-shaped positioning strips 9. The added multiple return springs 8 can push the two inverted U-shaped positioning strips 9 downwards, so that the multiple magnetic blocks 10 are respectively inserted into the multiple positioning grooves 11, and are not easily separated when they are attracted to the multiple base material layers 14. The base material layer 14 is Q345 steel, the high toughness transition layer 15 is high manganese steel, and the high hardness wear-resistant layer 16 is tungsten carbide alloy. The addition of Q345 steel base material layer 14 provides structural strength and adapts to equipment installation. The high toughness transition layer 15, high manganese steel (thickness 10-15mm), can absorb impact energy and prevent crack propagation. The high hardness wear-resistant layer 16, tungsten carbide alloy (thickness 5-8mm), resists material impact and wear, and extends service life. Two dovetail strips 6 are fully inserted into two dovetail grooves 12, and multiple magnetic blocks 10 are respectively inserted into multiple positioning grooves 11 and attracted to multiple substrate layers 14. By adding two dovetail strips 6 that are fully inserted into two dovetail grooves 12 and multiple magnetic blocks 10 are respectively inserted into multiple positioning grooves 11 and attracted to substrate layers 14, the position of the two dovetail strips 6 is locked to prevent [further damage].

[0024] As a second embodiment of this utility model:

[0025] The added base layer 14 is made of Q345 steel, providing structural strength and adapting to equipment installation. The high-toughness transition layer 15 is made of high-manganese steel (10-15mm thick), which can absorb impact energy and prevent crack propagation. The high-hardness wear-resistant layer 16 is made of tungsten carbide alloy (5-8mm thick), which resists material impact and wear and extends service life. The lower ends of multiple triangular reinforcing ribs 4 and multiple transverse reinforcing ribs 5 are attached to the base layer 14, which can concentrate the impact force of the base layer 14 and distribute it to the entire liner, avoiding local breakage, improving the overall rigidity of the liner, and reducing the risk of deformation. When it is necessary to disassemble the liner body 13, lift the two inverted U-shaped positioning strips 9 with force, so that multiple return springs 8 are compressed upward, forcing multiple magnetic blocks 10 to retract from multiple positioning grooves 11 into multiple positioning holes 7 respectively. Then pull the liner body 13 forward until the two dovetail strips 6 are completely withdrawn from the two dovetail grooves 12, and the disassembly of the liner body 13 can be completed.
