SEPARATING DEVICE FOR THE POTATO BARRIER MACHINE OR THE MACHINE FOR THE PRELIMINARY TREATMENT

摘要

A separating device for a potato harvester or pretreatment machine is provided for separating potatoes or a similar harvested crop from a mixture with lumps, stones and similar solids. For this purpose, a conveying device, which is a substantially dense mixture in the form of a transport stream, is used, from which the mixture is transferred to the area of at least one falling stage and is exposed to the transport medium in the form of an air stream. After that, respectively, at least the harvested crop, as well as solids, are sent further in the form of separate separated materials and removed from the separating device. The system according to the invention is characterized in that after the falling stage causing the mixture to loosen, at least one holding element is directed towards the falling separable materials and interacting with at least one air stream. Due to this, it is unexpectedly easy to achieve that, moving away from the retaining element in the form of appropriately sorted separate parts, at least the harvested crop and solids are separately directed further in the correspondingly opposite direction of transportation.
