<p>The roller- or belt-type conveyor, e.g. for an agricultural implement, has a scraper removing dirt from potatoes. The scraper (7) bears in a roughly tangental plane against the surface (1) to be cleaned, and is light pre-loaded. It turns freely about an axis (10,11) outside this surface. The scraper itself can be mounted in a holder (6) turning about this axis, and it can be spring-loaded, and there can be axial stops limiting holder movement.</p> |
