Separating device for a potato harvester

摘要

A separating device for separating a crop from a mixture with admixtures has a drop stage and a conveying device supplying the mixture in a conveyed stream to the drop stage. An air stream is supplied to the drop stage, wherein the mixture is falling in the drop stage and is affected by the air stream, wherein 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. The air stream interacts with the retaining element. Downstream of the retaining element the crop and solid bodies separated from the mixture are transported farther as separated individual parts in substantially opposite conveying directions. A diverting device is provided that can at least partially divert the conveyed stream upstream of the retaining element.

1. A separating device for a potato harvesting machine or a processing machine for separating a crop from a mixture of the corp with admixtures, the separating device comprising:
a drop stage; a conveying device supplying the mixture in at least one conveyed stream to the drop stage; a conveying medium in the form of an air stream supplied to the drop stage, wherein the mixture is falling in the drop stage and is affected by the air stream, wherein 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 the air stream interacts with the retaining element; 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; diverting means configured to completely divert, when activated, the at least one conveyed stream upstream of the retaining element and to discharge the at least one conveyed stream supplied by the conveying device directly into a downstream and/or adjacently positioned conveying zone without contacting the retaining element, wherein the retaining element and the air stream are configured to operate at reduced output or be switched off at least temporarily when the diverting means is activated.
