Document Type and Number:
WIPO Patent Application WO/2014/026766
Kind Code:
A3
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.
