Crop flow assisting device for harvesting header

A harvesting header comprising

• at least one draper belt system comprising a conveyor belt having a generally planar conveying surface operable to carry cut crop material in a conveying direction generally transverse to a direction of travel of the harvesting header in operation to a header discharge;
• a crop reel rotatable about a crop reel axis, said axis generally parallel with the conveying direction, said crop reel operable to, when rotated in operation, draw crop material onto the conveying surface of the conveying surface;
• at least one crop flow assistance device having a substantially smooth crop flow assistance surface, said crop flow assistance surface including at least a rearward portion that is located adjacent to and rearward of a rearward transverse edge of the conveying surface of the conveyor belt, and said crop flow assistance surface having a smooth concave curved portion that extends into a volume directly above the conveying surface, said volume defined in part by a lower planar boundary aligned with the conveying surface and said volume extending upwards from the said conveying surface, said volume also defined in part by a forward transverse planar boundary aligned with a forward transverse edge of said conveying surface and extending upwards from and in a direction perpendicular to said conveying surface, and said volume also defined in part by a rearward transverse planar boundary aligned with a rearward transverse edge of said conveying surface and extending upwards from and in a direction perpendicular to the conveying surface, wherein the curved portion of the crop flow assistance surface extends substantially into the volume, said crop flow assistance surface operable to roll crop material onto the conveying surface while the crop material is carried to the header discharge in operation.
