Cutting blades attached to chopping unit in movable feed mixer, comprising serrated segments particularly arranged along helical worm

摘要

The helical worm (2) accommodated inside the mixer is of a tapered shape and equipped with cutting blades (5) either stationary or swivel mounted (13) to its rim. Each of the cutting blades (5) has a curved front (6) provided with a serrated edge (7) and is joined in a particular angle in relation to a line (9) drawn from the rotation axle (4) to the rim (6) resulting in a precise chopping of the roughage. The teeth (7) can be fitted with cutting edges (7, 8) along one or both sides.
