The invention discloses a waste conveying device. The waste conveying device comprises a feeding platform (1) and a feeding base (2), wherein the feeding platform (1) is disposed on the feeding base (2), two guide rails (3) are arranged on the feeding base (2), two wheels (4) and two limiting bars (5) are arranged at the bottom of the feeding platform (1), the two limiting bars (5) are parallel to the guide rails (3) and are located on the outer sides of the two guide rails (3) separately, and the two wheels (4) are located on the inner sides of the two guide rails (3). When the waste conveying device is used, it is only needed to place waste on the feeding platform and push the feeding platform to move on the feeding base along the guide rails, time and labor are saved, and working efficiency is high.
