Abstract
A rotary cutter for a brush cutter. The cutter has a rotatable cylindrical drum with a plurality of flat, annular, collars mounted on the drum. The collars are fastened to the drum by their inner circular edge, are equally spaced apart on the drum, and extend transverse to the rotational axis of the drum. A cutting tooth mounting block is mounted between each adjacent pair of collars, the block located at the outer edge of the collars and spaced above the surface of the drum to provide a gap for passing chips and residue. The mounting block carries a detachable cutting tooth, the tooth extending forwardly generally tangentially from the block and terminating in a cutting edge above the collars.
Claims16
A rotary cutter for a brush cutter;
- the cutter having a rotatable, cylindrical drum (3);
- flat, annular-like, collars (9) having inner (11) and outer (13) edges, the collars (9) fastened to the outer surface (5) of the drum (3) by their inner (11) edge, the collars equally spaced-apart in a direction parallel to the longitudinal, rotational axis (7) of the drum (3) and each collar (9) extending transverse to the longitudinal axis (7) of the drum (3);
- a cutting tooth mounting block (27) fixedly mounted to, and extending between, each pair of adjacent collars (9), the mounting block (27) located at the outer, peripheral portion of the collars (9) and spaced well above the surface (5) of the drum (3) to provide a substantial gap (45) between the mounting block (27) and the drum (3) for use in dispersing chips and other material cut by the rotary cutter during its operation, each block (27) adapted to detachably mount a cutting tooth (55) with the cutting edge of the tooth located in front of the block (27) and above the outer edge (13) of the collars (9).
A rotary cutter having a rotatable cylindrical drum (3);
- a plurality of collars (9) fixedly mounted on the surface (5) of the drum (3), the collars equally spaced apart and extending transverse to the axis (7) of rotation of the drum (3);
- each adjacent pair of collars having two opposed mounting blocks (27) mounted on, and between, the collars on the upper peripheral portion of the collars, each collar of each pair of adjacent collars having two additional opposed mounting blocks (27) mounted on, and between, it and another adjacent collar, the two additional opposed mounting blocks circumferentially offset from the first two mounting blocks, the two additional blocks on one of the pair of collars circumferentially offset in one direction from the first blocks and the two additional blocks on the other of the pair of collars circumferentially offset in the opposite direction to the one direction from the first blocks.
