Abstract
A paintball conveying device includes a conveying chamber having one side formed with a paintball outlet. The conveying chamber includes a conveying member for conveying paintballs. A power unit includes a knob that unidirectionally drives a wheel to rotate. The wheel is connected with a spiral torsion spring configured to provide kinetic energy for rotating the wheel reversely. The wheel unidirectionally drives a big gear to rotate when rotated reversely. The big gear is meshed with a pinion gear adapted for synchronously linking a resistance gear and the conveying member to rotate. When the wheel is driven to rotate reversely by the spiral torsion spring, the conveying member is synchronously rotated to convey the paintballs. At least one resistance member is pivotally connect to one side of the resistance gear to move back and forth for leaning against the resistance gear, thereby supplying resistance when the conveying member is rotated.
