The invention belongs to the technical field of transportation devices, and particularly relates to a bridge construction feeding device which comprises a shell, a lifting device is installed in the shell, the lifting device comprises a chain and a hopper installed on the chain, a discharging port is formed in the shell, and a spherical-crown-shaped impact area for materials in the hopper to impact is arranged on the inner wall of the top of the shell. And the impact area is communicated with the discharge hole. When the discharging port structure is used, materials thrown out of the hopper can impact on the spherical crown-shaped impact area at the top of the shell, the materials impacting on the two sides of the spherical crown area can collide with each other when falling off, a part of kinetic energy can be consumed, the impact force of the materials during discharging is reduced, and therefore the impact damage degree of the materials to the discharging port structure is reduced, and ...
