ている。Generally, a waste straw shredding device configured as described above is often installed in a combine harvester to shred the threshed waste straw, and the waste straw is placed on the ground during operation with a rotary tiller. In order to make plowing easier, it is desirable to have short cut lengths of waste straw, but for example, when cultivating paddy rice after harvesting wheat, the shredded straw that has been plowed in can absorb water. To prevent it from floating on the surface of the field,
A long shredding length of the waste straw is desired, and there is a need for a waste straw shredding device that can change the shredding length of the waste straw.
そこで、従来では、切断される排ワラの切断長さを変更
するものとして、例えば実開昭６１−８０６３９号公報
に示されたものが提案されている。Therefore, conventionally, there has been proposed a method for changing the cutting length of the waste straw to be cut, as shown in, for example, Japanese Utility Model Application Laid-Open No. 61-80639.

なる場合があった。However, in the above structure, it is necessary to provide a plurality of cutting blades with different pitches between the rotary blades, and there is room for improvement in terms of structure and cost. Therefore, as shown in Fig. 7 (O, (U)), the rotary blade (1a) that acts on the receiving blade (2)
and a rotary blade (1b) that does not operate, and a receiving blade (1b) is provided.
Rotary blades (la), (lb), (3a) that act on cutting by moving the rotary blades (2) in the axial direction.
A structure was proposed in which the shredded length of the waste straw was changed by changing the pitch between the straws, but in this structure, as shown in Fig. 7 (
In the state of shredding short straw shown in a), the shredded short straw is thrown away without getting stuck between the rotating blades, but in the state of shredding long straw shown in Figure 7 (b), the shredded short straw is not jammed between the rotating blades. Rotary blade that does not shred long straw in three places (1), (
3b) and (3b) may become clogged, making it impossible to process.
