BUSH CUTTING ROTOR Russian patent published in 1995 - IPC

FIELD: forestry engineering. SUBSTANCE: rotor has a drive shaft. Disks 2 are rigidly mounted on the shaft. Support axles 3 join the disks together. Knives are hinge-mounted in between the disks. The knives have ledges on their front cutting edges 5 and radial cutout 6 along the axis of their symmetry. The least radius of the cutout is equal to the support axle radius. Each knife is symmetric relative to the crosswise plane passing through the cutout center, and the cutout is ellipsoid in shape. EFFECT: simpler design; higher reliability; longer service life of working tools; higher capacity. 2 dwg
