Abstract

A mulching apparatus including: a housing including a front opening and an inner wall; a rotor mounted in the front opening of the housing adjacent to the inner wall; and a liner mounting system for mounting a replaceable wear liner between the rotor and the inner wall, the liner mounting system including: an upper mounting provided at an upper edge of the inner wall, the upper mounting configured to releasably connect with the wear liner; and a lower mounting provided at a lower edge of the inner wall, the lower mounting configured to support the wear liner against the upper mounting and secure the wear liner to the inner wall.

Claims (23)

1. A mulching apparatus comprising:

a housing comprising a front opening and an inner wall;

a rotor mounted in the front opening of the housing adjacent to the inner wall;

a replaceable wear liner configured to be installed to and removed from the mulching apparatus while the rotor remains mounted in the front housing; and

a liner mounting system for mounting the replaceable wear liner between the rotor and the inner wall, the liner mounting system comprising:

an upper mounting provided at an upper edge of the inner wall, the upper mounting configured to releasably connect with the wear liner, the upper mounting comprising a top plate and an upper attachment mechanism securing the top plate to the upper edge of the inner wall; and

a lower mounting provided at a lower edge of the inner wall, the lower mounting configured to support the wear liner against the upper mounting and secure the wear liner to the inner wall;

wherein the top plate and the upper attachment mechanism are configured such that the wear liner can be slid between the top plate and the inner wall and held in place when the attachment mechanism is engaged.

2. A mulching apparatus according to claim 1 , wherein the upper attachment mechanism comprises a plurality of upper bolts that are arranged to match with slots cut into a liner top edge of the wear liner such that the slots of the wear liner can be slid against the bolts.

3. A mulching apparatus according to claim 1 , wherein the lower mounting comprises a bottom plate and a lower attachment mechanism configured such that the lower attachment mechanism removably secures the bottom plate and the wear liner to the inner wall.

4. A mulching apparatus according to claim 3 , wherein the lower attachment mechanism comprises a plurality of lower bolts that pass through the bottom plate, the wear liner, and the inner wall.

5. A mulching apparatus according to claim 1 , wherein at least one of the upper mounting and the lower mounting are configured to also act as a shearing or cutting element.

6. A mulching apparatus according to claim 1 , wherein at least one of the upper mounting and the lower mounting comprises a plurality of sections wherein each section is separately removable from the inner wall.

7. A mulching apparatus according to claim 6 , wherein each section is configured to be reversible such that an unworn side can be turned to be situated where a worn side was previously.

8. A mulching apparatus according to claim 1 , wherein the wear liner comprises:

a body configured to fit around the rotor of the mulching apparatus;

a plurality of slots at an upper end of the body; and

a flange provided at a lower end of the body and extending rearward from the body, the flange provided with a plurality of fastening holes.

9. A mulching apparatus according to claim 1 , further comprising a chain assembly provided rearward from the rotor, the chain assembly comprising:

a plurality of chains;

a chain mounting plate comprising a plurality of chain holders, each of the plurality of chain holders configured to support an individual chain; and

a chain support plate removably attached to the chain mounting plate to hold the plurality of chains on the chain holders of the chain mounting plate.

10. A mulching apparatus according to claim 9 , wherein each of the plurality of chain holders comprise a plurality of holes configured to receive one or more links of each of the plurality of chains and support the plurality of chains in place.
