[0036] In the above technical solution, clay removing plate 1 is close to the inner wall of excavator bucket 10, basically does not change the structure of excavator bucket 10, low in cost, and convenient for the modification of existing excavator bucket 10.

[0037] In the technical solution, driving assembly is provided to drive, when cleaning clay, clay removing plate 1 is driven by driving assembly, free end 13 rotates around driving end 14, and clay removing plate 1 rotates away from the inner wall side of excavator bucket 10, and the clay adhered to the inner wall of excavator bucket 10 is stripped off through the rotation of clay removing plate 1, to realize cleaning operation, simple and convenient operation, high efficiency.

[0038] In the above technical solution, clay removing plate 1 only works when cleaning clay, without affecting the normal work of excavator bucket 10.

[0039] In the above technical solution, clay removing plate is driven by driving assembly to clean clay, and excavator bucket can be at any position when cleaning clay, without requirement for the stroke and pose of excavator bucket, with good flexibility.

[0040] In this technical solution, the active drive component includes a mounting base 2, a drive rocker arm 3, and a drive unit 4. The mounting base 2 is fixed on the outer wall of the excavator bucket 10. The drive end 14 extends out of the excavator bucket 10 and is rotatably mounted with the mounting base 2. One end of the drive rocker arm 3 is fixedly connected to the drive end 14, and the other end of the drive rocker arm 3 faces the drive unit 4.

[0041] like Figure 2 As shown, when the clay removal device of this excavator bucket 10 removes clay from the inner wall of the excavator bucket 10, the driving unit acts on the end of the driving rocker arm away from the mounting seat, causing the driving rocker arm to rotate around the rotating mounting position on the mounting seat. Simultaneously, the free end 13 of the cleaning plate 1 also rotates around the driving end, that is, the cleaning plate moves relative to the inner wall of the excavator bucket 10 toward the opening of the excavator bucket 10, so that the cleaning plate 1 rotates away from the inner wall of the excavator bucket 10. As the cleaning plate 1 rotates relative to the inner wall of the excavator bucket 10, the clay adhering to the inner wall of the excavator bucket 10 is peeled off from the inner wall of the excavator bucket 10, thereby removing the clay from the inner wall of the excavator bucket 10.

[0042] In the above solution, the active drive component includes a mounting base 2, a drive rocker arm 3, and a drive unit 4.
