Claims

[Scope of utility model registration request]

A cutter shaft 2 to be rotated at high speed and a toothed shaft 3 to be rotated at low speed are horizontally supported on the machine frame 1 in parallel. A large number of rotary blades 4 having blade portions 4a are mounted in parallel at predetermined intervals in the axial direction,
The receiving tooth shaft 3 has a large number of receiving teeth a formed by combining two rings in parallel at a small interval, each facing each of the rotary blades 4 mounted in parallel on the cutter shaft 2. In the straw cutter with parallel rotary blades arranged and mounted in parallel at different parts, the receiving tooth shaft 3
A rotary blade 4 having a serrated blade portion 4a on the periphery of a disc-shaped blade, and a disc-shaped ring 50 having approximately the same diameter as the rotary blade 4. A tooth ring 5 having a gear-like tooth portion 51 without blades on the periphery of the tooth ring 5.
are formed by combining them in parallel, and the tooth ring 5 thereof
The pitch of the teeth 51a... of the tooth portion 51 of the teeth 51a...
A receiving tooth for a straw cutter with parallel rotary blades, characterized in that the teeth are set so as to be continuous in the circumferential direction at intervals that are large enough to fit into the culm of the straw.
