A spring 602 is provided in the empty slot 601, a fixing rod 603 is provided on one side of the bottom sealing plate bottom plate 1, limiting slots 604 are provided on both sides of the inner wall of the empty slot 601, a limiting block 605 is provided on one side of the fixing rod 603, a fixing rope 606 and a fixing part 607 are provided on one side of the bottom sealing plate cover plate 2, and the fixing part 607 can facilitate the fixation of the fixing rope 606.

[0026] In this embodiment, the bottom sealing plate bottom plate 1 and the bottom sealing plate cover plate 2 form an integral body, the sealing sleeve 5 is sleeved and fixed on the bottom sealing plate bottom plate 1, the bottom sealing opening 4 is adapted to the bottom sealing plate bottom plate 1, the bottom sealing plate bottom plate 1 is clamped in the bottom sealing opening 4, and the top of the bottom sealing plate cover plate 2 is in contact with the bottom of the excavator body 3;

[0027] Specifically, the sealing sleeve 5 can improve the sealing effect between the bottom sealing plate and the bottom seal 4;

[0028] In this embodiment, one end of the spring 602 is fixedly mounted on the bottom of the empty slot 601. The empty slot 601 is adapted to the fixing rod 603. One end of the fixing rod 603 extends into the empty slot 601 and is fixedly mounted on the other end of the spring 602.

[0029] Specifically, the spring 602 can facilitate the rebound reset of the fixing rod 603;

[0030] In this embodiment, the two sides of the extending end of the fixing rod 603 are fixedly installed with limit blocks 605, and the two groups of limit grooves 604 are respectively adapted to the two groups of limit blocks 605, and the two groups of limit blocks 605 are respectively slidably installed in the two groups of limit grooves 604;

[0031] Specifically, the limiting block 605 combined with the limiting slot 604 can prevent the fixing rod 603 from being separated from the empty slot 601;

[0034] In this embodiment, the fixing member 607 is fixedly mounted on the bottom cover plate 2 on one side of the fixing rope 606. The fixing rope 606 and the fixing member 607 are connected. The fixing mechanism 6 has two sets of slots 7, which are respectively adapted to the protruding ends of the two sets of fixing rods 603. The protruding ends of the two sets of fixing rods 603 are respectively engaged in the two sets of slots 7.

[0035] Specifically, the fixing rod 603 is engaged in the slot 7 to fix the bottom sealing plate 1 in the bottom sealing opening 4;

[0036] In this embodiment, the cavity 8 is formed to avoid the positions of the two sets of fixing ropes 606.

Loosen the two sets of fixing ropes 606, and due to the rebound and reset effect of the springs 602, one end of the two sets of fixing rods 603 will extend out of the empty slots 601 and be clamped into the corresponding clamping slots 7, so that the bottom sealing plate bottom plate 1 can be fixed in the bottom sealing opening 4. The above operations can be performed in reverse to complete the disassembly of the bottom sealing plate assembly (the bottom sealing plate bottom plate 1 and the bottom sealing plate cover plate 2). The disassembly and assembly of the bottom sealing plate assembly does not require the help of external tools, which is relatively convenient.

[0039] Since the first elastic block 9 and the second elastic block 10 have good elasticity themselves, and the first elastic block 9 and the second elastic block 10 are both semicircular and their protruding ends are in contact with each other, the first elastic block 9 and the corresponding second elastic block 10 can offset the impact force received by each other, thereby further improving the anti-collision effect of the bottom sealing plate assembly.
