長くて不揃いとなる欠点があつた。 Conventionally, among a pair of rotating shafts that are approximately parallel to the culm direction of the culm, a scraping disk was placed on the rotating shaft near the culm opening, and a disk blade was placed on the other shaft at appropriate intervals in the axial direction. In a disc cutter that cuts the culm by feeding it from above the cutting disk in a state substantially parallel to the rotating shaft, the culm is forcibly fed from the root side by a conveying device, and as a result, the tip of the culm is cut. The side of the culm is ejected in a delayed manner, and the scraping disk acting on the stock side gives priority to the stock side, and this scraping action on the stock side causes the tip to become more slanted. Since the cutting section enters the cutting section in a state where the tip is tilted, and the cutting section cuts this inclined tip side, there is a drawback that the cutting length is long and uneven.

とす。 Therefore, in order to eliminate the above-mentioned drawbacks, this invention is constructed as follows. That is, among a pair of rotating shafts that are approximately parallel to the culm direction of the culm, a scraping disk is placed on the rotating shaft near the culm opening, and a disk blade is placed on the other shaft at appropriate intervals in the axial direction. In the disk cutter installed at the culm opening of the threshing machine so that the culm is supplied from above the raking disk, an elastic guide is used to bring the culm into pressure contact with the raking disk and guide it to the cutting section. A plurality of rods are arranged along the outer periphery of the raking disk, and the position where the guide rod rakes the culm and starts to press against the disk is shifted toward the discharge port side as it approaches the tip. The configuration of the disk cutter is as follows.

穂先部までも定寸に切断されるのである。 With such a configuration, this invention has the following technical effects. That is, when the culm is discharged from the culm opening of the threshing machine 5 with the ear tip in a lagging position and is supplied from above the raking disk 3, the culm is moved by the guide rod 7,
By deviating the positions 11, 12, 13, and 14 where the culms 8, 9, and 10 begin to press the culm against the raking disk 3 toward the culm opening toward the tip, the culm of the raking disk 3 Scraping starts from the tip side, and the culm moves to the cutting part 6 through the guide rods 7, 8,
While being guided by 9 and 10, the tip delay is corrected. In this way, the scraping disk 3 scrapes the culm from the tip side, and the cutting part 6
By sending it to
The culms are easily cut at the same time by the disc blade 4, and even the tips of the ears are cut to a fixed size.

側程、排稈口側へ偏位させている。 Next, an embodiment of this invention will be explained based on the drawings. Reference numeral 5 denotes a threshing device, and 15 and 16 indicate grain conveying devices stretched along one side of the grain culm.The conveying device 15 holds and conveys the base of the grain culm while threshing the tip side. A disk cutter is attached to the rear of the culm discharge port of the threshing device 5, and the axis of the disk cutter is oriented in a direction substantially parallel to the culm direction of the grain culms transferred by the conveying devices 15 and 16. It has rotating shafts 1 and 2, and the rotating shafts 1 and 2 include
A large number of disc blades 4, 17 are arranged at approximately equal intervals over the entire length of the culm. Further, among the rotating shafts 1 and 2, a star foil-shaped scraping disk 3 is disposed adjacent to a disk blade 17 on the rotating shaft 1 near the culm opening to improve the uptake of the culm. There is. Disc blade 4,
17 face each other and rotate in opposite directions with a difference in rotational circumferential speed, so that the culm scraped by the scraping disk 3 is cut by the cutting portion 6 where the circumferential edges of the disk blades 4 and 17 overlap. The object is to fall to the opposite side. Reference numeral 18 is a clamping rod for scooping up the culm and conveying it to the top of the disk 3. Guide rods 7, 8, 9, and 10 are located approximately in the middle of the axial mounting interval of the scraping discs 3, and are attached to a stay fixed to the cutter frame 19 with their tips aligned with the periphery of the scraping discs 3. It is suspended from the disk 20, and the culm is scraped into the disk 3.
The positions 11, 12, 13, 14 where the guide rods 7, 8, 9, and 10 begin to scrape the culm and come into pressure contact with the disc 3 are the closer to the tip of the culm. It is deviated towards the mouth.

されるため、切断長さは一定となる。 The culm sent out from the culm opening of the threshing device 5 is
The culm is conveyed by the conveying device 16 and the clamping rod 18, falls onto the raking disk 3, and is raked by the raking disk 3 to the cutting part 6. As mentioned above, the tip of the culm is Because of their delayed stance, stockholders are trying to push them. However, at this time, the positions 11, 1 of the guide rods 7, 8, 9, 10, which push the culm into pressure contact with the disc 3, start to come into pressure contact.
Since the guide rods 7, 8, 9, and 10 are deviated toward the culm opening as the tip side approaches, the pressing action of the guide rods 7, 8, 9, and 10 on the culm comes from the tip side, and the tip side is scraped first. It will be scraped by the engraving disk 3,
While the culm moves to the cutting section 6 while being pressure-guided by the guide rods 7, 8, 9, and 10, the tip delay is corrected, and the culm is simultaneously cut by the disc blades 4 and 17, so that the cutting length can be reduced. becomes constant.

You may. Also, as in another embodiment of the guide rod shown in FIG. 4, guide rods 7', 8', 9',
