Screener rake esp. for rainwater overflow collection basins has rake teeth shaped for collected material to be pushed from gaps between teeth

摘要

The rake has several rake bars (2) and rake cleaners with teeth (1), moving through the bars. The pitch of the tooth face (4) facing the outlet side, between the rake bars and up to the front bar edge (3), rises at a flat acute angle ( alpha ) relative to the rake bar axis (6), and then rises into an obtuse or right angle. The tooth face (7) away from the outlet side extends toward the rake bar at a flat obtuse angle ( beta ). The rake is with/without ejector plates fitted into rake gaps, with straight or curved incline.
