| 摘要 |
This invention relates to an improved ditch water cleaning apparatus characterized by a partially covered open ended frame for insertion in the ditch, an upwardly and rearwardly inclined screen at the upstream end of the frame effective to interrupt the flow of water within the ditch and screen the debris therefrom, a propeller-like brush journalled for rotation about an axis normal to the plane of the screen and so located relative thereto that each arm of the brush successively sweeps the surface of the latter and removes any debris therefrom onto the covered portion of the frame lying immediately therebehind, and brush drive means operatively connected to the brush. The unit also includes a novel comb to pick the debris from the brush bristles preparatory to its moving onto the screen.
