Dredging device

Abstract

The present disclosure provides a dredging device including a body. The body includes a salvaging device salvaging sludge, a crushing device crushing the sludge, a sludge discharging device discharging the sludge, and an adjustiug device adjusting a height of the dredging device and moving. The salvaging device includes a driving wheel, a driven wheel, a transmission belt, salvaging hoppers. The dredging device further includes a second motor, crushing wheels, and a baffle. The second motor is turned on to drive a first gear to engage with second gears, so that rotating shafts drive the crushing wheels to crush sludge and larger stones. The baffle blocks an upper portion of the crushing wheels, which avoids the sludge splashing on a worker.
