Abstract
An adjustment mechanism for a rotary disc chipper apparatus includes an axially displaceable shaft attached to a chipper disc, at least one gear disposed in relation to the axially adjustable shaft and a drive member engageable with the at least one gear to produce axial movement of the axially displaceable shaft and the chipper disc.
Claims19
In combination, an adjustment mechanism for use in a chipper apparatus, said chipper apparatus including a rotary disc having a plurality of cutting blades and a disc shaft supporting said disc and a stationary bedknife wherein said adjustment mechanism adjusts the relative clearance between said cutting blades and said bedknife, said adjustment mechanism comprising:
- an axially displaceable shaft;
- at least one gear disposed in relation to said axially displaceable shaft;
- and
- an engagement member disposed in relation to said at least one gear to effect rotation thereof so as to produce axial movement of said axially displaceable shaft wherein the output of said axially displaceable shaft is connected to an axially movable cartridge, said disc shaft being connected to said cartridge to produce corresponding movement of said rotary disc.
A chipper apparatus comprising:
- a chipper disc having a series of cutting blades, said chipper disc having a center shaft attached to said chipper disc;
- a stationary knife disposed in relation to said cutting blades of said chipper disc;
- and
- an adjustment apparatus for adjusting the position of the chipper disc relative to the stationary knife, said adjustment apparatus including an axially displaceable shaft attached to the center shaft of said chipper disc, at least one gear disposed onto said axially displaceable adjusting shaft, and an engagement member for engaging said at least one gear to effect rotation of said axially displaceable shaft and subsequent axial movement of said chipper disc relative to said stationary knife.
