するようにしている。2. Description of the Related Art The culm discharged after threshing with a combine is cut into short pieces and sprayed on a field.
The cutting of the culm is performed by a disk cutter in which cutting blades are arranged at predetermined intervals on a rotating shaft provided substantially parallel to the culm direction of the culm. And so on so that the straw can be widely and uniformly sprayed on the field.

することを課題とする。The diffusion device in the conventional disk cutter is designed on the assumption that the culm is long. For this reason, when the culm was short, the spread of cut leaves to the root of the plant was not sufficient, and the application to the field was biased toward the tip side. An object of the present invention is to make it possible to uniformly disperse cut straw in both long and short culms.

A helical tip 6 that feeds from the approximate center toward the tip of the culm and a helical tip 7 that feeds in the direction of the root are provided on a rotating shaft 5 that is laid below the base. It can be fixed to move.

The cut straw is dropped on the rotating shaft 5 and the root side of the straw is diffused in the root direction by the root spiral 7, and the tip side is diffused in the head direction by the tip spiral 6 to form a whole. Although it is spread widely and uniformly, if the culm is long,
When the stem side of the cut straw falls on the stem spiral 7 and is spread well, and the culm is short, the stem side of the cut straw is moved by moving the stem spiral 7 toward the ear and fixed. It falls on the former spiral 7 and spreads toward the root of the stock. still,
Sending the straw in the direction of the stock root If the stock spiral 7 is lengthened, most of the cuts will be scattered to the stock side and not evenly spread,
In the present invention, by moving the stem spiral 7 in the axial direction, it corresponds to the length of the culm, so that the amount of spraying on the stem side can be adjusted.

いる。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 2, a disc cutter 3 according to the present invention is mounted on a rear portion of a combine body 10. Straw chips and dust at the time of threshing are discharged from the dust discharging fan 11 inside the combine machine body 10 into the cutter machine frame 12. At the upper part of the combine body 10, there are provided a feed chain 13 for nipping the grain culm and threshing the ears at the threshing unit and feeding it backward, and a culm chain 14 for sending the threshed culm further backward and threshing. The finished culm is sent out onto the cutter frame 12. The cutter machine frame 12 has a horizontally long box shape, and supports a scraping shaft 15 and a cutting shaft 16 on the front and rear of the upper portion thereof in a horizontal manner.
The cutting section 4 is formed by arranging the cutting blade 7 and the cutting blade 2 at a predetermined interval, and a switching plate 19 for opening and closing the supply port 18 is provided at the upper end.
