An extension groove is provided at the contact between the front plate body and the rear plate body. A circle of fixing holes 3 is provided on the outer edge of the concave surface. The concave surface is used to accommodate the wear surface body assembly 8 to make it flush with the surface of the substrate 1, reducing the direct impact of materials on the substrate 1. Two connecting holes 4 are provided in the middle of the concave surface, and the two connecting holes 4 are used to connect with the wear surface body assembly 8 to provide additional fixing points. The first chute 5 and the first slide bar 6 are respectively provided at the upper and lower ends of the substrate 1, so that a plurality of liner plates 801 can be spliced with each other to form a continuous liner plate 801 system. The reinforcing ribs 7 are arranged in a woven shape inside the substrate 1. The woven reinforcing ribs 7 are evenly distributed, which can effectively resist the impact and wear of materials, extend the service life of the liner plate 801, improve the structural stability of the substrate 1, reduce the risk of deformation and damage, can effectively protect the inner wall of the hopper, and improve the service life and working efficiency of the equipment;
