A conveying device with a revolvingly led, extensively extended conveying element, which forms a conveying section with a conveying surface, and a return section, which is arranged below the conveying section. The conveying element is deflected in each case in two head-end regions, which are spaced from one another along the conveying direction. A wiper device for wiping foreign objects led along on the conveying surface of the conveying element is arranged in the front head-end region, in which the conveying element is deflected from the conveying section into the return section. The wiper device includes a wiper unit with a receiving blade, which runs transversely to the conveying direction, as well as a wiper blade, which is mounted on the wiper unit and forms a flexible wiper lip projecting toward the conveying element beyond the receiving blade.
