[0035] Among them, this river channel silt cleaning device utilizes the existing excavator for river channel cleaning, and cooperates with the hydraulic system of the excavator, wherein the main parts of the telescopic arm include a telescopic cylinder, a piston, a sealing ring and a hydraulic pipeline, etc. The hydraulic system sends hydraulic oil into the telescopic cylinder through a pump, so that the plug extends to the right, so as to adjust the length and angle of the telescopic arm 2, and the silt cleaning of rivers at different heights can be achieved through the bucket 3; and by setting the structure of the bucket 3 on the excavator body 1, it is convenient for the bucket 3 to adjust its capacity. The new type of use can increase the capacity of the bucket 3 by welding the connecting piece 5 on the outside of the bucket 3, and by welding the bucket 3 with buckets 7 with different capacities, it is convenient for the excavation device to be used in different scenarios, and by adjusting the expansion groove 8 and the edge plate 9 at the end of the bucket 7, it is convenient to expand the excavation width of the bucket 3 and improve the cleaning rate of the excavation device. By inward inclination of the edge plate 9, the excavated silt can be collected and processed, and the excavated silt can be uniformly regularized, reducing the loss of silt, and improving the tidiness and cleaning rate of the silt.

[0036] Bucket side plates 11 are provided at both ends of the bucket 3, and two edge plates 9 are relatively arranged on the outside of the two bucket side plates 11. The bucket side plates 11 are the existing structure of the bucket 3 and are used to limit the side of the excavated materials.
