Claims

[Scope of utility model registration request]

A plurality of cutting blades are arranged in parallel on one side of two parallel axes, and the other axis has a one-on-one relationship with each cutting blade on the one axis.
raking blades for short cutting that engage correspondingly with each other, and raking blades for long cutting of the same shape that are parallel to some of the raking blades for short cutting that are not adjacent to each other with a predetermined interval. By arranging the cutting blades in parallel and moving one shaft in the axial direction, the cutting blade of the one shaft and this one-to-one
By engaging the corresponding short-cutting blade on the other shaft, or by engaging a part of the cutting blade on one shaft with the long-cutting blade on the other shaft, the straw can be changed to a long or short length. In a straw removal cutting device for a combine harvester that is capable of cutting, the pair of the short cutting blade and the long cutting blade have their polished surfaces facing each other, and between the scraping blades, A large-diameter collar that does not touch the opposing cutting blades and rotates together with both scraping blades is interposed, and a small-diameter collar that is movable on each axis is interposed between the other blades. Features: Straw cutting device for combine harvesters.
