Separating Device for a Potato Harvester

摘要

A separating device for separating crop from a mixture with admixtures has a drop stage and a conveying device supplying the mixture to the drop stage. The mixture is falling in the drop stage and the drop stage effects loosening of the mixture. A retaining element is arranged downstream of the drop stage so as to face the mixture falling in the drop stage, wherein downstream of the retaining element the crop and the solid bodies separated from the mixture are transported farther as separated individual parts in substantially opposite conveying directions. An air stream interacts with the retaining element and exits as a discharged air stream from the retaining element. A functional unit extends substantially above the retaining element and interacts at least partially with the discharged air stream and produces one or more partial air streams. The partial air streams are controllable by the functional unit.

主权项

1. A separating device for a potato harvesting machine or a processing machine for separating a crop from a mixture with admixtures, the separating device comprising:
a drop stage; a conveying device supplying the mixture to the drop stage, wherein the mixture is falling in the drop stage and the drop stage effects loosening of the mixture; a retaining element arranged downstream of the drop stage so as to face the mixture falling in the drop stage, wherein downstream of the retaining element the crop and solid bodies separated from the mixture are transported farther as separated individual parts in a first conveying direction and a second conveying direction, respectively; an air stream interacting with the retaining element exiting as a discharged air stream from the retaining element; a functional unit extending substantially above the retaining element; wherein the functional unit is configured to interact at least partially with the discharged air stream and to produce one or more partial air streams, wherein the one or more partial air streams are controllable by the functional unit.
