The utility model adopts a bottom sealing plate composed of a concave press profile and reinforcing ribs, which can not only improve the bending strength of the sealing plate itself, but also reduce the risk of the bottom sealing plate being deformed by being squeezed by protruding stones."
[0004] When in use, the above device uses two symmetrically arranged semicircular concave panels spliced together to form a circular overall structure. The utility model uses a bottom cover plate that combines a concave press and reinforcing ribs, which can improve the bending strength of the cover plate itself. However, when the above device is in use, it is not convenient to fix and install the bottom cover plate. When the bottom cover plate is damaged during use, it is not convenient to disassemble it and the damaged part cannot be replaced. For this reason, we propose an excavator plate assembly.

[0009] As a preferred technical solution of the present invention, the number of the first circular grooves is four, and the four first circular grooves all pass through the bottom of the frame.
[0010] As a preferred technical solution of the present invention, reinforcing ribs are fixedly installed on the bottom of the reinforcing plate. The number of the reinforcing ribs is four, two of which are perpendicularly crossed with the other two.
[0011] As a preferred technical solution of the present invention, the bottom of the frame and the bottom of the cover plate are in the same plane.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. The excavator plate assembly is used in conjunction with the frame and the cover plate, and at the same time utilizes the first circular groove, so that the first bolt rotatably connected inside the first circular groove can fix the cover plate, and the mounting plate installed at the bottom of the cover plate can use the second bolt to further fix the cover plate, and the installed mounting plate can enhance the strength of the cover plate.
