PURPOSE: A serial screw conveying system and a conveying equipment using the same are provided to convey a plurality of bushings with a different pitch respectively by driving a single rotation shaft. CONSTITUTION: A serial screw conveying system(200) includes a rotation force generating element(110), a serial screw conveying shaft(120) connected to the rotation force generating element and formed with at least two or more screw groups(121-125) on an outer peripheral surface with different pitches, a bushing unit(140) having a bushing(143) composed of at least two or more pieces to be screw-coupled with the screw groups and formed with female screw parts on an inner peripheral surface, and a bushing rotation preventing element(147) for preventing the bushing from rotating with the serial screw conveying shaft together, and stoppers(126-129) formed on boundaries of the screw groups for separating the respective screw groups.
