The invention provides a device for automatic cleaning of trashracks. The device comprises a rake arm upheld by a support which is movable sideways in parallel with the trashrack. A wedge-shaped rake is pivotally mounted at the lower end of the rake arm, which by drive means is moved downwards and upwards along the trashrack, the rake thereby engaging the trashrack. During the downward movement the rake engages the trashrack only with its lower edge at which means are arranged striving to pivot the rake towards the trashrack. During the upward movement the rake is pressed against the trashrack with the whole end surface facing the trashrack.
