The invention relates to the technical field of ecological restoration, and discloses a salvage auxiliary device used for ecological restoration and capable of solving the problem of inconvenient garbage treatment. The salvage auxiliary device comprises a shell, and a material containing box is fixedly connected in the shell. Through the combined action of the material containing box, a left pressing tool, a right pressing tool, a connecting rod, a cone pulley, a first rotating plate, a first movable plate and a second rotating plate, salvaged and contained garbage is automatically compressed, redundant water in the garbage is squeezed out, the size and weight of the garbage are reduced, the space utilization rate is increased, convenience is provided for subsequent transportation treatment, the treatment cost is effectively reduced, a the actual use requirement is met, the opening and closing state of a discharging port is controlled, support is provided for garbage compression operation, extruded sewage is discharged through water leakage holes of a baffle, after compression operation is completed, the discharging port is not shielded any more, garbage blocks are transferred under the action of the garbage blocks, space is vacated for subsequent garbage compression operation, and the garbage treatment operation is orderly carried out.
