Abstract: A combine harvester has a conveying channel for conveying crop material from the combine harvester's cutting mechanism to its threshing mechanism. The conveying channel has several conveying chains, which are guided on a lower deflection drum and on sprockets arranged on an upper drive shaft. A plurality of raking pins extend at a distance on both sides of the combine harvester, roughly parallel to the chain links, and provide a means for preventing the accumulation of grain in the region of upper deflection in the combine harvester. The raking pins have their free ends that protrude beyond the chain links. Furthermore, the raking pins advantageously are constructed as bolts which are attached along with the conveying bars to the conveying chains.
