Embodiment Construction

[0029] exist figure 1 The combine harvester 1 according to the invention shown in sectional view in the figure carries in its front region a height-adjustable harvesting device 3 which harvests ripe grain 9 over a large width and collects the grain laterally Together and provided to the inclined conveyor mechanism 10. The grain reaches the threshing mechanism 4 via an inclined belt conveyor 10 in a known manner, where figure 1 In the view of , the threshing mechanism 4 includes a threshing cylinder 11 , a turning cylinder 17 arranged behind the threshing cylinder 11 and a threshing basket 12 . A first grain stream, consisting mainly of grain, straw and chaff, separates from the grain through the holes of the threshing basket 12 and falls onto the pretreatment floor 13 . The grain flow on the pretreatment floor 13 is transported backwards in the direction of the cleaning device 5 by the jolting motion of the pretreatment floor 13 . The pretreatment floor 13 is provided with ...

Abstract

The invention relates to a combine harvester, which is provided with a conveyer base (22) arranged in fornt of a cleaning unit (5) for conveying grains, which has surface structures (39,40; 45). The surface structures allows the grain current laterally and mutualyl dividually deflect relative to the average conveying direction of the grain on the conveyer base (22,58). The units (34,35; 38) are provided upstream of the surface structures for combing the current at a fraction of a width of the surface structures (39,40; 45).

Description

technical field [0001] The invention relates to a combine harvester and, in a combine harvester, in particular to the distribution of threshed grain to be re-cleaned on a conveying floor of the combine harvester. Background technique [0002] DE 697 09 534 T2 discloses a combine harvester with a threshing section in the form of a drum and a forward floor arranged below the threshing section, the threshing section having an axis oriented in the longitudinal direction of the combine harvester, The forward floor collects the grains that have been dislodged from the grain. The longitudinal orientation of the drums has the consequence that more grain falls on the left and right edge regions of the forward bed than in the center of the forward bed. The reason for this is that, on the one hand, a centrifugal force is generated on the grain due to the rotation of the drum, which causes the grain to fall, after passing through the holes of the threshing basket, not generally vertica...
