Abstract

In a method for screening earth, gravel and the like containing comparatively large-size objects (1) and finer material (2), the material (1, 2) is moved into a screening drum (3) through an opening (13), whereupon the drum is rotated in a first direction, the large-size objects being retained in the drum (3) and the finer material being forced out of the drum through a screening element (8). When the drum is rotated in the opposite direction after the screening has been completed, the large-size objects are discharged from the drum through the opening (13). The drum is rotatably mounted on a frame (5) which is connected to the front loader (7) of a tractor (6). A pocket provided inside the drum retains the large-size objects (1) when the drum is rotated in the first direction . When the drum is rotated in the opposite direction, the large-size objects (1) are allowed to leave the pocket and are discharged from the drum (3) through the opening (13).
