Dredging device and dredging control system

The invention discloses a dredging device and a dredging control system. A sucking-discharging dredging shaft comprises a first dredging shaft and n dredging units; the first dredging shaft is connected with a first dredging unit; the n dredging units are connected with each other through a manner of staggering with each other by a first set angle; each dredging unit comprises a dredging section and m cleaning devices; the m cleaning devices are arranged on the dredging section through a manner of staggering with each other by a second set angle; a first rotating motor drives the sucking-discharging dredging shaft to do rotating motion in a rotating process; the m cleaning devices do shaking motion according to the staggered second set angles so as to generate centrifugal force; scraping blades are used for cleaning cement dust generated on the inner wall of a sucking-discharging oblique three-way pipe; the cement dust rising during discharging dust through a stirring tank is not easily attached on multiple d
