The invention relates to the technical field of test equipment, and discloses a combined-driven dredging trolley. The combined-driven dredging trolley comprises a ship body, wherein a tractor is movably connected to one side of the top of the ship body; a winch is movably connected into the tractor; a drum is fixedly installed at one side of each of the front surface and the back surface of the winch; a steel wire rope is fixedly connected outside each drum; a fixed barrel is fixedly connected to one side of the front surface of the winch; a connection rope is fixedly connected to one side outside the fixed barrel; a fixed block is fixedly connected to one side of the tractor; a fixed plate is movably connected to the top of the fixed block; and a bolt is movably connected into the fixed plate. According to the combined-driven dredging trolley, through cooperative use among a hydraulic rod, a rake arm and a rake head, the lifting of the rake head can be realized; and through cooperative arrangement among a motor, a telescopic rod, the rake arm and the rake head, the rake arm and the rake head can be driven to rotate through the motor, and angle adjustment for the rake head is realized, so that the effect of comprehensive sludge suction is achieved.
