<p>In the present invention, there is disclosed a device to adjust the run of a circular grading sieve by changing the position of its output shaft (5), coupled with an upper plate (4), relative to the position of its input shaft (1), coupled with a lower plate (2). The lower plate (2) is coupled with a central plate (3) by means of lower bolts (7) disposed in lower slots (21) of the lower plate (2) enabling sliding of the lower plate (2) and the central plate (3) relative to each another. The upper plate (4) is coupled with the central plate (3) by means of through-bolts (8) disposed in circular grooves (41) of the upper plate (4) and middle grooves (31) of the central plate (3) and further by means of a swivel pin (6). The circular grooves (41) enable angular displacement of the upper plate (4) around the swivel pin (6) that is arranged in the central plate (3) in slidable manner. Axes of the input shaft (1) and the output shaft (5) are not perpendicular to a plane being formed by the upper plate (4), middle plate (3) and the lower plate (2) resting on each other.</p> |
