Water channel sludge treatment device for water conservancy project

The canal sludge treatment device for the water conservancy project comprises a protective shell, a primary treatment mechanism, a secondary treatment mechanism and a sludge suction pump, a filtering and smashing assembly can be driven through a first driving assembly to complete sludge filtering work and impurity smashing work, and meanwhile the primary treatment mechanism and the secondary treatment mechanism are arranged on the protective shell. A knocking roller in the knocking separation assembly can be driven to swing in a reciprocating mode to knock a Y-shaped double-trough, the situation that sludge and smashed sundries adhere to the inner wall of the Y-shaped double-trough is avoided, a baffle is made to swing in a reciprocating mode, intermittent discharging work of the sludge and the smashed sundries is achieved, in addition, the mixing assembly is driven to complete mixing work and discharging work, and the discharging efficiency is improved. In the material mixing process, water in the sludge can
