After the excavator bucket 10 unloads earth, the bucket oil cylinder 40 is controlled to continue to be retracted to drive the excavator bucket 10 to continue to overturn backward, at this time, the earth cleaning plate 1 is driven by the passive driving assembly to separate from the inner wall of the excavator bucket 10, thereby realizing the cleaning of the clay on the inner wall of the excavator bucket 10. That is, the "retraction of the bucket oil cylinder 40 and driving the excavator bucket 10 to overturn backward by a certain angle" in the above-mentioned scheme refers to that after the bucket oil cylinder 40 drives the excavator bucket 10 to complete the unloading of earth, the bucket oil cylinder 40 continues to drive the excavator bucket 10 to overturn backward, at this time, the earth cleaning plate 1 is driven by the passive driving assembly to rotate around the driving end 14, and the free end 13 of the earth cleaning plate 1 rotates away from the inner wall of the excavator bucket 10.
[0035] That is, the "certain angle" in the present scheme generally refers to the angle after the bucket oil cylinder drives the excavator bucket to dump all the materials in the bucket, and the bucket oil cylinder continues to be retracted to drive the excavator bucket to continue to rotate and overturn backward. The angle can separate the inner wall of the excavator bucket from the earth cleaning plate.
[0036] In the above-mentioned technical scheme, the earth cleaning plate 1 is tightly arranged on the inner wall of the excavator bucket 10, basically does not occupy the content of the excavator bucket 10, basically does not affect the working efficiency of the bucket, and has simple structure, low cost and low failure rate.
[0037] In the above-mentioned technical scheme, the earth cleaning plate 1 is tightly arranged on the inner wall of the excavator bucket 10, basically does not change the structure of the excavator bucket 10, has low cost, and is convenient for modification of the existing excavator bucket 10.
[0038] In the present technical scheme, the passive driving assembly is arranged to drive, in the process of cleaning earth, the bucket oil cylinder 40 is retracted and drives the excavator bucket 10 to overturn backward by a certain angle, the earth cleaning plate 1 is driven by the passive driving assembly to rotate around the driving end 14, the free end 13 of the earth cleaning plate 1 rotates away from the inner wall of the excavator bucket 10, the clay adhered to the inner wall of the excavator bucket 10 is stripped off through the rotation of the earth cleaning plate 1, thereby realizing the operation of cleaning earth, which is simple and convenient to operate and has high efficiency.
[0039] In the above technical solution, the soil clearing plate 1 only works during soil clearing and does not affect the normal operation of the excavator bucket 10.
[0040] In this technical solution, the passive drive assembly includes a mounting base 2, a drive rocker arm 3, and a guide member 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 guide member 4. After the bucket cylinder 40 retracts and drives the excavator bucket 10 to flip backward at a certain angle, the end of the drive rocker arm 3 facing the guide member 4 slides on the guide member 4. The drive free end 13 rotates around the drive end 14, and the soil cleaning plate 1 rotates away from the inner wall of the excavator bucket 10.
[0041] like Figure 2 As shown, when the clay removal device of the excavator bucket 10 removes clay from the inner wall of the excavator bucket 10, after the bucket cylinder 40 drives the excavator bucket 10 to empty all the clay inside the bucket, the bucket cylinder 40 continues to drive the excavator bucket 10 to rotate and tilt backward.
