PROBLEM TO BE SOLVED: To provide a sludge scraping machine that can prevent scum floating on a water surface of a sedimentation pond from remaining, and allows a drop-off prevention member of a flight plate to be easily installed even in a limited installation space.SOLUTION: A sludge scraping machine includes: a flight movable body 8 that scrapes sludge in a sedimentation pond 1; a stopper 28 disposed at both end sides of the flight movable body 8; a water-level guide rail 27 that guides traveling of the flight movable body 8; and a guard rail 36 that restricts upward movement and lateral movement of the flight movable body 8 traveling on the water-level guide rail 27. The flight movable body 8 includes a guide shoe 24 that can slide freely on the water-level guide rail 27. The guard rail 36 restricts the upward movement and the lateral movement of the flight movable body 8 by striking of the stopper 28 against the guard rail 36. The stopper 28 and the guard rail 36 are located below a water surface of the sedimentation pond 1. |
