The invention discloses a double-drive self-propelled spiral desilting device in the technical field of hydraulic machines. The double-drive self-propelled spiral desilting device comprises a first walking mechanism, a second walking mechanism, a first rotation driving mechanism and a second rotation driving mechanism. The first walking mechanism and the second walking mechanism are of the same structure and are oppositely arranged. The first walking mechanism comprises a cylindrical support, a star wheel mechanism is arranged on the periphery of the cylindrical support which is rotatably connected with a supporting pipe, the lower parts of opposite ends of the two supporting pipes are connected with two mounting plates respectively, an arc shield is arranged between the two mounting plates, a rotatable screw blade shaft is arranged below the arc shield, and a desilting mechanism is arranged behind the arc shield. Space accommodating the desilting mechanism is arranged between the first walking mechanism and the second walking mechanism, the first rotation driving mechanism drives the first walking mechanism to rotate, the second rotation driving mechanism drives the second walking mechanism to rotate, and the rotation directions of the first rotation driving mechanism and the second rotation driving mechanism are adjustable. The double-drive self-propelled spiral desilting device is high in desilting efficiency and can realize complete desilting and conveniently clear messy objects in the desilting mechanism.
