This embodiment is configured as described above, and the uncut grain culm is taken into the cutting header (17) via the reel (19), and the root of the uncut grain culm is cut by the cutting blade (20). At the same time, the cutting grain culm is sent from the substantially central part of the header (17) to the supply chamber (18) via the grain culm scraping drum (21), and the shaving grain culm is cut by the cutting grain culm supply chain conveyor (24). It is supplied to the threshing unit (4) and is successively shredded by the screw type handling cylinder (5), and the shattered grains are sorted while being dropped by the sorting mechanism (6), and only the sized grains are taken out to the grain tank (7). It is a thing.

Thus, by providing the raising device (23) on the uncut side of the left side of the header (17), the grain stalks that lie down in the left and right direction are gradually raised as the machine progresses, and are cut and scratched well. In addition, when cutting with the cutting blade (20), even if the grain culm is sent to the cutting blade (20) in the front-back fall state, the tip side is raised upward by the guide surface (30a). In this state, the rising posture of the grain culm is increased, and the grain culm is reliably cut without being caught between the upper and lower cutting blades (20). Furthermore, the guide surface (30a)
When the cutting height is low, for example, soybean cutting work, and part of the upper part is taken in at the same time, the intrusion on the guide surface (30a)
It is prevented by and is prevented from being simultaneously scratched inside.

Furthermore, by providing the conveyor roller (22) in the grain stalk non-scraping action area on the grain stalk scraping path (26) from the cutting blade (20) to the scraping drum (21), the non-scraping action is achieved. This eliminates the inconvenience of the occurrence of accidents such as culm clogging due to the accumulation and retention of culm in the area, and the corns are always fed accurately and smoothly to the scraping drum (21). In addition, when the grain culm is attached to the outer peripheral surface of the roller (22) and is rotated around the non-acting side, the scraper (33) removes the scraped object to a state of scraping it to prevent the scraping around. Thus, it is possible to prevent inconvenience that the grain (culm) or the like is wrapped around the surface of the roller (22), and to always promote good feeding of the grain (culm).
When the carry-on object not sufficiently removed by the scraper (33) reaches the position below the conveying roller (22), it is discharged to the outside of the machine through the exclusion hole (35) opened below this, and the effect of removing the carry-on object. Can be further improved.

[Advantages of the Invention] As is clear from the above embodiments, the present invention scratches the uncut grain culm reel (19), the cutting blade (20) for cutting the grain culm, and the cut grain culm. A combine grain stalk scraping device comprising a scraping drum (21) for plugging in a cutting header (17), wherein the reel (19) and the scraping drum are provided between the cutting blade (20) and the scraping drum (21). The cutting blade (2
0) A conveyance roller (22) having a width substantially equal to the left-right width is provided substantially parallel to the cutting blade (20), and the rear descending inclined type for guiding the grain culms from the conveyance roller (22) to the scraping drum (21). Scraper (33)
Is provided on the rear side of the conveying roller (22), and a front descending inclined guide body (30) forming a triangular shape in a side view by the combination of the conveying roller (22) and the scraper (33) is provided on the front side of the conveying roller (22). The conveyor roller (22), the guide body (30) and the scraper (33) forming a triangle are arranged at the bottom of the triangular space between the reel (19) and the scraping drum (21). (19) and guide body (3
0), the upper surface of the conveyor roller (22), the scraping drum (21) and the scraper (33) can be smoothly fed to the scraping drum (21). In addition, the guide body (3
0) and scraper (33) for mowing header (17)
The bottom part is reinforced so that the strength can be easily improved, the distance between the cutting blade (20) and the scraping drum (21) can be shortened more easily than before, and the front and rear width of the mowing header (17) can be made compact and the manufacturing cost can be reduced. The above can be easily achieved.
