Abstract
A rotor assembly operable with anvil mechanism for comminuting waste wood and other fragmentable material has a rotating drive shaft with a series of rotors fixed in axially spaced relation thereon. A series of radially projecting hammers mechanisms are situated along the axis of the shaft and powered by the shaft. Fragmenting knives are removably secured to the leading outer portions of the hammer mechanisms. The hammer mechanisms include sidewisely reversible hammer legs having portions received by the rotors sidewisely contiguously.
Claims20
In a fragmenting rotor assembly for waste wood and other fragmentable material:
- a. a drive shaft and mechanism for driving said shaft in a direction of rotation, said drive shaft incorporating axially spaced radially projecting rotors along its axis;
- b. a series of radially projecting side for side reversible hammer mounting hammer supports selectively situated along the axis of said shaft on said rotors and powered by said shaft, the hammer supports having radially outward heads with a rotatively leading face portion and a parallel trailing face portion adapted to selectively mount said hammers radially outward of said rotors;
- c. said hammers comprising fragmenting knives removably secured to the rotatively leading portions of said hammer supports;
- d. said knives having axially extending reducing edges;
- and
- e. said hammer supports being mounted at the sides of said rotors to partly overlie said rotors axially to define axially abutting adequate radial support for paths of knife travel.
In a fragmenting rotor assembly operable with anvil surface for comminuting waste wood and other fragmentable material:
- a. a drive shaft and mechanism for driving said shaft in a direction of rotation, said drive shaft incorporating axially spaced discs along its axis;
- b. a series of side for side reversible radially projecting knife supports situated along the axis of said shaft on said discs and powered by said shaft, the knife supports having radially outward heads with a generally radial leading face portion and a substantially paralled trailing face portion;
- c. fragmenting knives removably secured to said leading face portions of said knife supports;
- d. said knives having axially extending reducing edges and said leading and trailing faces having fastening elements for mounting said knives selectively on said face portions;
- and
- e. said knife supports being mounted at the sides of each disc with the discs being so spaced that said knives on the confronting sides of adjacent discs have axially overlapping paths of travel.
In a fragmenting rotor assembly operable with an anvil mechanism for fragmenting waste wood and other fragmentable material:
- a. a drive shaft assembly including a mechanism for driving said shaft assembly in a direction of rotation about an axis of rotation, said drive shaft assembly incorporating axially spaced radially projecting rotors along its axis;
- b. a series of side for side reversible radially projecting hammer supports powered by said shaft assembly situated along the axis of said shaft assembly and positioned to lie sidewisely contiguously to said rotors along said axis, the hammer supports extending radially outward of said rotors and having heads with a rotatively leading face portion and a trailing face portion;
- c. hammers comprising fragmenting knives removably secured to said leading portions of said hammer supports;
- d. said knives having axially extending reducing edges;
- and
- e. one of said contiguous hammer supports and rotors being sidewisely shouldered and providing shoulder receiving surface to be partly sidewisely received by shoulder received surface provided on the other.
In a fragmenting rotor assembly, operable with anvil surface for fragmenting waste wood and other fragmentable material:
- a. a drive shaft and mechanism for driving said shaft in a direction of rotation about an axis, said drive shaft incorporating axially spaced radially projecting rotors along its axis;
- b. a series of radially projecting side for side reversible hammer legs situated along the axis of said shaft on said rotors and powered by said shaft, the hammer legs having heads with a rotatively leading face portion and a generally parallel trailing face portion radially outward of said rotors and with knife securing elements on each face portion;
- c. fragmenting knives having axially extending reducing edges removably secured to the leading portions of said hammer heads;
- d. said hammer legs being mounted at the sides of said rotors to partly overlie said rotors axially and radially conformed to said rotors;
- and
- e. deflector members situated axially between said hammer legs and adjacent rotors, said deflector members being in substantial radial alignment with said hammer legs on adjacent rotors.
