Cleaning assembly for a combine harvester

A cleaning assembly for a combine harvester comprising:

• a conveyor for transporting at least one of or both of a threshed or separated mixture of grain and contaminants from at least one of or both of a threshing or separating device to an inlet of the cleaning assembly,
• screens for cleaning the mixture fed to the inlet of the cleaning assembly, which are able to be subjected to an action of an air flow by a fan, and
• a cross conveyor, arranged at the inlet of the cleaning assembly, for evening out a lateral distribution of the fed mixture,
• wherein the cross conveyor includes an open, air-permeable design, being arranged in the air flow provided by the fan,
• wherein the air flow flows against and through the cross conveyor substantially horizontally, and
• wherein a number of slats is arranged to a rear of the cross conveyor, which are able to be flowed through by the air flow that has previously flowed through the cross conveyor.

A combine harvester for harvesting crop, the combine harvester comprising:

• a threshing unit configured to thresh the crop;
• and
• a cleaning assembly configured to clean the threshed crop, wherein the cleaning assembly includes a conveyor for transporting at least one of or both of a threshed or separated mixture of grain and contaminants from at least one of or both of a threshing or separating device to an inlet of the cleaning assembly, screens for cleaning the mixture fed to the inlet of the cleaning assembly, which are able to be subjected to an action of an air flow by a fan, and a cross conveyor, arranged at the inlet of the cleaning assembly, for evening out a lateral distribution of the fed mixture, wherein the cross conveyor includes an open, air-permeable design, being arranged in the air flow provided by the fan,
• wherein the cross conveyor includes an endless traction means having drivers distributed in a spaced-apart manner along a length of the traction means, wherein the traction means circulates about deflection wheels, and
• wherein the drivers have a U-shaped profile which is upwardly open when a respective driver to one of the plurality of traction means is located on an upper strand of the cross conveyor.
