Abstract
The bar screen of the present invention includes a bar rack and a cleaning rake. The bar rack includes a plurality of aligned bars and is adapted to be at least partially positioned within the channeled water. The cleaning rake is movably coupled to the bar rack and includes a plurality of tooth segments. Each tooth segment includes a base portion and a plurality of teeth. The base portion is coupled to the cleaning rake, and the plurality of teeth is connected to the base portion. Each tooth of the plurality of teeth is adapted to be inserted between adjacent bars on the bar rack to remove debris that has accumulated on the upstream side of the bar rack. The teeth are breakable from the base when the teeth engage immovable debris trapped within the bar rack.
