Description of the Related Art A disk cutter is configured to cut a culm, which is discharged from a threshing part of a combine in a sideways state, between a cutting blade and a receiving blade arranged at a predetermined interval along the culm body direction. It's being used. As the receiving blade, there is a disk having a protrusion formed on the outer periphery and having a scraping action, or a combination of a receiving blade and a scraping disk similar to a cutting blade. In this disk cutter, a cutting blade is arranged at a predetermined interval on a cutting rotary shaft rotating at a high speed via a collar, and a receiving blade is arranged on a scraping rotary shaft rotating at a low speed so as to face and close to the cutting blade via a collar. To form the cutting part of the disk cutter. The cutting performance is better if the cutting blade and the receiving blade are arranged as close as possible, but the production accuracy of the cutting disk blade, receiving blade and collar is limited, so when the disk cutter is assembled, Each part is manufactured in such a size that the clearance between the cutting blade and the receiving blade is widened with a margin in manufacturing dimensions so that the receiving blade does not abut. For this reason, the interval between the cutting blade for cutting the tip side of the culm and the receiving blade is wide, and the flexible culm tip side may be bent and difficult to cut.

ことに着目して、ディスクカッターの切断性能を良好に
することを課題とする。In the present invention, it is necessary to reduce the interval between the cutting blade and the receiving blade particularly at the cutting position of the spike, because the spike side of the culm is flexible and easily bent with respect to the base of the stock. It is an object of the present invention to improve the cutting performance of a disc cutter by focusing on the above.

好に切断される。The cutting blade 2 is arranged at predetermined intervals on the cutting rotary shaft rotating at high speed by the collar 6 on the basis of the stock base, and the receiving blade 3 is mounted on the rotating rotary shaft at low speed by the collar on the basis of the stock base. 5, the cutting blades 2 are arranged in a crossing state in a side view while approaching the cutting blades 2. However, when the cutting blades 2 are arranged close to the base side of the receiving blades 3, each of the receiving blades 3 By manufacturing the collar 5 that regulates the interval with a minus tolerance with respect to the reference dimension, the interval between the receiving blades 3 becomes shorter, and the collar 6 that regulates the interval between the cutting blades 2 is produced with a plus tolerance with respect to the standard dimension. As a result, the interval between the cutting blades 2 is widened, and the interval between the receiving blade 3 and the cutting blade 2 is wide at the base of the stock, but narrow at the tip side, so that the flexible tip side of the culm can be cut well. Become. Also,
When disposing the cutting blade 2 close to the tip side of the receiving blade 3, the collars 5 and 6 are manufactured with the opposite tolerance to that described above.
The interval between the cutting blade 2 and the receiving blade 3 becomes narrower on the tip side, so that the culm is cut well.
