A soil separator consists of a frame of a rectangular shape on which in bearings a row of parallel shafts is mounted, on which sprockets of special configuration with the same gap between them are put on. On each of two adjacent shafts the sprockets are shifted for a pitch and enter into the adjacent gaps. The sprockets on the shafts have different external diameter and are set from the largest to the least one forming conditionally conic surfaces arranged toward each other. |
