DISPOSITIF D'INTRODUCTION POUR MOISSONNEUSE-BATTEUSE A ECOULEMENT AXIAL

The invention relates to a drawing-in device for axial-flow combine harvesters, in which there are arranged in the drawing-in channel longitudinally relative to the direction of travel two conveying drums which extend parallel to one another and are driven in opposite directions of rotation and which convey the crop from the cutting unit to the threshing device. The aim of the invention is to improve the crop flow from the cutting unit to the threshing and separating drum, reduce the power requirement and at the same time achieve high conveying capacities. The object on which the invention is based is to design and arrange the drawing-in device in such a way that the crop is fed to the threshing and separating drum in the best possible way by means of an advantageous conveying movement and a high acceleration. The features of the invention are that the two conveying drums arranged in the drawing-in channel ... and an approximately cylindrical annular gap is present in the conveying region between each outer circumference of the conveying drums and the respective housing parts.
