Abstract

Nóż skrawająco-rozdrabniający do mulczera charakteryzuje się tym, że posiada co najmniej jedno ostrze (2) w formie cylindrycznego słupka z częścią skrawającą, które osadzone jest w trzonku noża (1) w otworach ustawionych pod kątem β w zakresie 20÷70° w stosunku do powierzchni osadzenia trzonka noża (1). Ostrza (2), (3), (4) usytuowane są równoległe do siebie. Ostrza (3), (4) odchylone są od położenia centralnego o kąt α w zakresie od 5° do 20° w jednej lub w dwu płaszczyznach.The cutting and shredding knife for a mulcher is characterized in that it has at least one blade (2) in the form of a cylindrical column with a cutting part, which is mounted in the knife shaft (1) in holes set at an angle β in the range of 20÷70° in relation to the mounting surface of the knife shaft (1). The blades (2), (3), (4) are located parallel to each other. The blades (3), (4) are deflected from the central position by an angle α in the range of 5° to 20° in one or two planes.
