The first card slot 33 is used for the bottom of the inner panel 20 to be embedded. A bent section 321 bent inwardly is provided at the top of the outer wall 32. The bent section 321 extends upwardly and is pressed against the outer side of the inner panel 20. After the inner panel 20 is inserted into the first card slot 33, the bent section 321 is used to press the inner panel 20 inward so that the portion of the inner panel 20 located in the first card slot 33 is pressed tightly against the outer surface of the inner wall 31. In this way, the bottom of the inner panel 20 is fixedly connected to the top of the wear-proof plate 30, ensuring that the connection between the inner panel 20 and the wear-proof plate 30 has better sealing. The bottom of the wear plate 30 is provided with an inner groove wall 34 and an outer groove wall 35 located outside the inner groove wall 34. Both the inner groove wall 34 and the outer groove wall 35 extend vertically downward to form a second groove 36 with a downward opening. The bottom of the inner groove wall 34 is provided with a bent section 341 that is tilted outward to partially cover the opening of the second groove 36. The bottom corner seal 40 includes a vertically extending first section 41 and a second section 42 that is bent inward from the bottom of the first section 41. The top of the first section 41 is inserted into the second groove 36, and the second section 42 is overlapped and fixed to the upper surface of the floor 52.
