The invention discloses a dirt removal device for a salt drainage pipeline, and belongs to the technical field of dirt removal for pipelines. The dirt removal device for the salt drainage pipeline comprises a hose, wherein a driving motor is installed in the center of the left side of the hose, a propeller is installed at the output end, on the left side, of the driving motor, the outer wall of a rotating shaft is connected with a brush in a sleeved manner, an ultrasonic transmitter is installed on the right side of the rotating shaft, a camera protecting cover is installed on the right side of the ultrasonic transmitter, and a camera is installed on the left side of the inner chamber of the camera protecting cover. According to the dirt removal device for the salt drainage pipeline, the ultrasonic transmitter gives out ultrasonic waves to remove dirt, the pipeline and the dirt shake, so that the formed dirt scatters, gets loose, is broken and drops off, and is not prone to being attached to the wall of the pipeline, and then, a rotating motor rotates to drive the brush to rotate so as to further remove the formed dirt attached to the wall of the pipeline. The dirt removal device for the salt drainage pipeline is convenient to operate through monitoring of a remote terminal, and is easy to operate, good in dirt removal effect, high in working efficiency and easy to popularize.
