[0023] like Figure 2 and Figure 3 As shown, the first positioning assembly includes a convex strip 10 arranged on the plate body 1 and a first sealing plate 13 arranged on the wear-resistant outer plate body 8. The plate body 1 is provided with a first limiting groove 9 for the convex strip 10 to be embedded. The sizes of the two second limiting grooves 11 are adapted to each other with a first sealing plate 13. The wear-resistant outer plate body 8 is provided with a second limiting groove 11 for the first sealing plate 13 to be embedded. The cross-sectional shape of the convex strip 10 is an isosceles trapezoid. The first limiting groove 9 is provided with a fixing bolt 12. The fixing bolt 12 passes through the wear-resistant outer plate body 8 and is threadedly connected to the plate body 1. Through the detachable wear-resistant outer plate body 8, when the wear-resistant outer plate body 8 is damaged, it can be replaced in time, so that the plate body 1 maintains good wear resistance.

[0024] When two plate bodies 1 are to be horizontally spliced, first align the convex strip 10 of one plate body 1 with the first limiting groove 9 and fit it in, which not only completes the pre-positioning effect of the splicing, but also improves the tightness of the splicing of the two plate bodies 1. Then, the first sealing plate 13 is embedded in the two first limiting grooves 9 and bonded to complete the horizontal splicing of the two plate bodies 1.

The length of the slide rail 16 is the same as the length of the T-shaped plate 15. The cross-sectional shape of the second sealing plate 18 is a right-angled trapezoid, and a triangular ramp 17 is provided on the plate body 1 to fit with the fixed plate 14. The second sealing plate 18 is embedded in the gap between the triangular ramp 17 and the wear-resistant outer plate body 8.

[0026] When two plate bodies 1 are spliced ​​longitudinally, first slide the T-shaped plate 15 of one plate body 1 into the slide rail 16, and the side surfaces of the two ends of the T-shaped plate 15 are flush with the side surfaces of the fixed plate 14, and then bond the second sealing plate 18 to the fixed plate 14 and the triangular ramp 17 wear-resistant outer plate 8 respectively, thus completing the longitudinal splicing of the two plate bodies 1. The operation is simple and convenient, which greatly reduces the difficulty of pre-positioning when splicing the plate bodies 1 horizontally and vertically, and at the same time improves the stability of the connection when the bonding solidifies, and has good practicality.
