The invention belongs to the field of channel desilting, and relates to a
wharf desilting device which comprises a riverbed. A
wharf is fixedly arranged at the upper side of the riverbed, a groove is formed in the front side of the
wharf, and a rack seat is fixedly arranged at the rear side of the groove; a first sliding groove is formed in the upper side of the groove, and a second sliding groove is formed in the lower side of the groove. According to the present invention, the
sludge accumulated on the riverbed can be stirred through the desilting device, so that the desilting device can smoothly extract the
sludge on the riverbed, the situation that the
sludge cannot be extracted due to accumulation is avoided, the desilting range of the desilting device can be enlarged under the assistance of a moving device, the effect of increasing the dredging area without additionally arranging the dredging device is achieved, the cost is saved, and meanwhile, the device can prevent a pipeline and a sludge inlet from being blocked.
