The broaching arm extends to the wall of the silo and is curved opposite to a direction of rotation of the rotor. A holder is connected to one of the leaf springs arranged in a center position of the leaf spring packet at a free end thereof. Outwardly positioned leaf springs of the leaf spring packet are slidably supported at the holder. A broaching tool is attached to the holder of the broaching arm.
