Abstract
The invention relates to a separation system for a potato harvesting machine or a preparation machine for separating potatoes, or similar crops, from a mixture of clods, stones, and similar solid bodies. A conveying assembly is thereby utilized to feed the essentially compact mixture as a delivery flow, from where the mixture displaced into the area of at least one drop stage, and thereby influenced by way of a conveying means in the form of an air stream, can be separated. Thereafter, at least the harvested material and the solid bodies, respectively, can be moved on as individual separated goods, and can be moved out of the separation system. The system according to the invention is characterized in that subsequently to the drop stage bringing about a loosening of the mixture, at least one retaining element located opposite the falling separated goods and interacting with the at least one air stream is provided. It is thus achieved in a surprisingly simple way that from there, at least the harvested material and the solid bodies, respectively, can be moved on separately in an essentially opposite conveying direction as sorted individual lots.

27. A separation system for separating a crop from a mixture, the separating system comprising:
-
a conveying device supplying a substantially compact mixture as a conveyed stream, the mixture comprising the crop and admixtures in the form of clods, rocks, and similar solid bodies; at least one drop stage arranged downstream of the conveying device and effecting loosening of the mixture supplied by the conveying device to the at least one drop stage; means for supplying an air stream to the mixture, wherein the air stream is interacting as a conveying medium with the mixture; at least one retaining element downstream of the at least one drop stage, wherein the at least one retaining element is facing the crop and the admixtures falling down within the at least one drop stage and is interacting with the air stream such that, beginning at the at least one retaining element, the crop and the admixtures are separately conveyed as sorted individual parts in opposite conveying directions, respectively, and separately discharged from the separation system. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52)
