River channel bottom layer sludge cleaning device

The invention relates to a river bottom layer sludge cleaning device, and belongs to the technical field of water conservancy dredging equipment, the river bottom layer sludge cleaning device comprises a transport vehicle, a base, a folding machine arm, a sludge conveying pipe and a sludge hinge suction part, the base is fixed on a carriage of the transport vehicle, and the top of the base is rotatable; the folding arms can be unfolded and extended; and a sludge outlet of the sludge reaming and sucking part is communicated with a sludge inlet of the sludge conveying pipe. Firstly, the transport vehicle is quickly moved to the bank side of a to-be-cleaned riverway, then the folding machine arms are unfolded to adapt to the height difference between the riverway and the land, and finally the sludge reaming and sucking part sinks into the bottom in the riverway to suck sludge in the riverway. The sludge cleaning device is simple in structure, high in maneuverability, convenient to operate, small in disturbance t
