[Detailed description of the invention] Industrial applications The present invention relates to a reaping device for a combine harvester.

BACKGROUND ART AND PROBLEMS TO BE SOLVED BY THE INVENTION A raking reel is provided above the front of the cutting blade device to engage the grain culm and rak it rearward without rotating. The base of the grain culm that has been raked into the wall of the grass machine is harvested by the cutting blade device. The harvested grain culms are placed on an endless transport belt on the rear side of the cutting blade device and transported, are raked and collected by a rear auger, and are transported to a threshing device by a transport device.

When engaging and raking grain culms with this raking reel, it is difficult to properly weed the grain culms on the uncut frame side at the wall of the weeding machine that weeds the grain culms on the uncut culm side. In particular, when the grain culms are lying down and intertwined, weeding cannot be done smoothly. Therefore, on the front side of the wall of this weeding machine, a rake-up lug that moves from the front side to the upper rear side by rotation of an endless body with a lug is used to separate the grain culms. A weed cutting device is provided that separates the grass on the raking reel side and on the outside of the weed cutting machine wall while raking up the grass.

The weeding device for weeding the grain culms is installed on the wall of the weeding machine, but if the wall of the weeding machine is wide, it will be difficult to weed the grain culms smoothly, so it must be made as thin as possible.
