[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] See also Figure 1-3 A wear-resistant finger-shaped plate includes a plate body 1, a plurality of finger-shaped teeth 2 extending outward from one end of the plate body 1, a gap is provided between two adjacent finger-shaped teeth 2, and the distance between the gaps is greater than the width of the finger-shaped teeth 2, and the two finger-shaped plates are engaged with each other through the finger-shaped teeth 2.
[0017] A reinforcing strip 8 is fixedly connected to the bottom of the finger-shaped tooth 2, and the reinforcing strip 8 can improve the strength of the finger-shaped tooth 2.
[0018] A support block 9 is fixedly connected to one end of the bottom of the plate body 1 away from the reinforcing strip 8 , and the support block 9 and the bottom of the reinforcing strip 8 are located in the same plane, and the entire plate body 1 is supported by the reinforcing strip 8 and the support block 9 .
[0019] A plurality of countersunk holes 4 are provided on the top of the plate body 1, and a screw anti-loosening assembly is fixedly connected to the bottom of the countersunk hole 4, and the screw anti-loosening assembly is located between the reinforcing strip 8 and the supporting block 9. A screw is inserted into the inner thread of the countersunk hole 4, and the bottom of the screw passes through the screw anti-loosening assembly.
