Abstract: The invention relates to a coarse dirt collector (7) for removing coarse material from a pulper (1). The coarse dirt collector (7) comprises a support arm (8) with a collecting basket (9). The collecting basket (9) consists of a frame (11) on which tines (Z) are fixed by means of a grid. The coarse dirt collector can be pivoted into and out of the pulper, to which end it moves about an axis of rotation (A) positioned at an angle to the plane that is perpendicular to the longitudinal axis (P) of the pulper. Said angle is between 20° and 40°. The advantage of said device is that the coarse dirt collector (7) has to carry out only one movement between its collecting and unloading position and unloading can take place automatically without need for a special scraping device. Because of the position of the tines (Z) there is no risk of undesirable loss of coarse material prior to unloading.
