DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] Embodiment 1, as Figure 1-4 As shown, a pipeline dredging mechanical arm includes a base 1, a fixed plate 2 is arranged at the upper end of the base 1, an outer arm 3 is arranged on the outer surface of the lower end of the fixed plate 2, and an operating hole 4 is arranged inside the base 1. When the sludge inside the pipeline needs to be cleaned, the four sets of universal wheels 6 arranged at the lower end of the base 1 will move the base 1 to the top of the pipeline so that the operating hole 4 is aligned with the pipeline opening. At this time, the first cylinder 7 inside the outer arm 3 will push the first inner arm 9 to move downward, thereby pushing the fixed column 15 and the fourth movable circular plate 16 to move downward, and the rotating column 25 arranged at the lower end of the fourth movable circular plate 16 is moved to the inside of the sludge. The motor 23 arranged at the lower end of the fourth movable circular plate 16 will drive the rotating column 25 to rotate through the rotating shaft 24. When the rotating column 25 rotates, it will drive multiple sets of silt breaking knives 26 to rotate, and the sludge in the pipeline is crushed. At the same time, the crushed sludge will be transported into the inside of the silt guide pipe 17 through two sets of silt suction ports 22 and the silt discharge pipe 18 inside the fourth movable circular plate 16, and finally the sludge is discharged to clean the sludge in the pipeline.

[0023] Embodiment 2, as Figure 1-4As shown, a pipeline dredging robot arm is provided with a first inner arm 9 inside an outer arm 3, and a second inner arm 12 is provided inside the first inner arm 9. When it is necessary to clean the sludge at different depths inside the pipeline, the first cylinder 7 inside the outer arm 3 will push the first movable circular plate 8 and the first inner arm 9 to move downward. When the outer surface of the lower end of the first movable circular plate 8 contacts the inner surface of the lower end of the outer arm 3, the second cylinder 10 inside the first inner arm 9 will push the second movable circular plate 11 and the second inner arm 12 to move downward. When the outer surface of the lower end of the second movable circular plate 11 contacts the inner surface of the lower end of the first inner arm 9, the third cylinder 13 inside the second inner arm 12 will push the third movable circular plate 14 and the fixed column 15, thereby adjusting the downward movement depth of the rotating column 25, and cleaning the sludge at different depths inside the pipeline. When the outer surface of the lower end of the third movable circular plate 14 contacts the inner surface of the lower end of the second inner arm 12, the maximum downward movement depth of the robot arm is reached.

[0024] How it works

[0025] It should be noted that the utility model is a pipeline dredging mechanical arm. When in use, the motor 23 can drive the rotating column 25 to rotate through the rotating shaft 24. When the rotating column 25 rotates, it will drive multiple groups of silt breaking knives 26 to rotate, so as to crush and disperse the silt inside the pipeline. The two groups of silt guide pipes 17 and silt discharge pipes 18 can discharge the crushed and dispersed silt, so as to complete the silt cleaning inside the pipeline. The first cylinder 7 arranged inside the outer arm 3 can push the first inner arm 9 to move downward, the second cylinder 10 arranged inside the first inner arm 9 can push the second inner arm 12 to move downward, and the third cylinder 13 inside the second inner arm 12 can push the fixed column 15 and the rotating column 25 to move downward, and the moving height of the rotating column 25 is adjusted, so that the multiple groups of silt breaking knives 26 can crush and disperse the silt at different depths inside the pipeline, so as to facilitate the cleaning of the silt. The four groups of universal wheels 6 can conveniently move the device to different places to clean the pipeline silt.
