Claims

[Scope of utility model registration request]

A first rotary cutter 3 comprising a large number of cutting blades 3a in the axial direction is provided in a fixed position, and an arrangement interval D in the axial direction of the cutting blades 4a provided on one side is provided.
_{The second} rotary cutter 4 and the third rotary cutter 5, which are different from the arrangement interval _D1 in the axial direction of the cutting blades 5a...2 provided on the other side, are connected to the first rotary cutter 3 whose respective axes Q and R are different from each other. The support member 7 is parallel to the axis P of the support member 7.
A pivot point that passes approximately the midpoint of the straight line connecting the axis Q of the second rotating cutter 4 and the axis R of the third rotating cutter 5, and is parallel to the axis P of the first rotating cutter 3. The support member 7 is pivotably supported around a support axis X, and by switching the swinging posture of the support member 7, one of the second rotary cutter 4 or the third rotary cutter 5 is moved to the first position. This stem culm shredding device is configured with a shredding length switching structure such that when the other rotary cutter approaches and overlaps with the first rotary cutter 3, the other end separates from the first rotary cutter 3.
