Abstract

A horizontal grinder chipper with interchangeable rotors which allows for rapid changing of said interchangeable rotors. Where the interchangeable rotors each are in the form of a cassette which can be easily inserted into and in between a first frame portion 1302 and a second frame portion 1303. A hydraulically actuated pivoting clamshell cassette covering upper portion 920 configured to pivot to an open orientation for removal of a first rotor cassette and for insertion of a second rotor cassette.

First claim

I claim:

1 . A continuous track propelled horizontal grinder comprising:
a first frame portion with a first frame portion slot therein and a second frame portion, spaced apart from said first frame portion, said second frame portion with a second frame portion slot therein; said first frame portion and said second frame portion being coupled to a third frame portion configured to support an internal combustion engine; said first frame portion having a feed end frame to cassette slot defining surface and an output end frame to cassette slot defining surface each with a plurality of bearing housing mount fasteners receiving holes therethrough; a first, at least partially, preassembled rotor cassette having a rotor shaft therein and having a predetermined rotor cassette bottom portion shape from a first frame portion slot in a first frame portion slot, wherein said first frame portion slot has a bottom portion having said predetermined rotor cassette bottom portion shape and is configured to receive therein and support from below said first preassembled rotor cassette; and a second preassembled rotor cassette comprising; a. a rotor shaft; b. a first side bearing housing mount; C. a second side bearing housing mount; d. a rotor; e. a first side bearing; and f. a second side bearing; said second preassembled rotor cassette being configured to be interchangeable with said first preassembled rotor cassette by being capable of being lowered into said first frame portion slot and said second frame portion slot in an absence of said first, at least partially, preassembled rotor cassette; and a plurality of bearing housing mount fasteners configured to be inserted through said plurality of bearing housing mount fasteners receiving holes to retain said second preassembled rotor cassette in said first frame portion slot.

2 . The continuous track propelled horizontal grinder of claim 1 wherein said first, at least partially, preassembled rotor cassette comprises a lower rotor portion and an upper attachment portion.

3 . The continuous track propelled horizontal grinder of claim 1 wherein an upper attachment portion has a first side bearing housing mount with parallel sides configured to allow a lower rotor portion to slide down through first frame portion slot and be engaged and supported from below by a frame structure at a bottom portion of said first frame portion slot.

4 . The continuous track propelled horizontal grinder of claim 3 further comprising a plurality of holes through said upper attachment portion to receive said plurality of bearing housing mount fasteners when being used to retain said second preassembled rotor cassette in said first frame portion slot.

5 . The continuous track propelled horizontal grinder of claim 4 wherein said
second frame portion is positioned with a parallel relationship with said first frame portion;
said third frame portion is configured to support the internal combustion engine having a horsepower characteristic in excess of eight hundred horse power.

6 . The continuous track propelled horizontal grinder of claim 5 wherein said first, at least partially, preassembled rotor cassette is a first fully preassembled rotor cassette.

7 . The continuous track propelled horizontal grinder of claim 6 wherein said second preassembled rotor cassette is a second fully preassembled rotor cassette.

8 . The continuous track propelled horizontal grinder of claim 7 wherein said first fully preassembled rotor cassette comprises a first mount and a second mount configured to mate with said first frame portion and said second frame portion, respectively.

9 . The continuous track propelled horizontal grinder of claim 8 wherein each of said first mount and said second mount further comprises one of the plurality of bearing housing mount fasteners.

10 . The continuous track propelled horizontal grinder system of claim 9 wherein said plurality of bearing housing mount fasteners are located above a central longitudinal axis of a rotor shaft.

11 . A continuous track propelled horizontal grinder comprising:
a first frame portion with a first frame portion slot therein and a second frame portion, parallel to and spaced apart from said first frame portion, said second frame portion with a second frame portion slot therein; said first frame portion and said second frame portion being coupled to a third frame portion configured to support an internal combustion engine having a horsepower characteristic in excess of eight hundred horse power; said first frame portion having a feed end frame to cassette slot defining surface and output end frame to cassette slot defining surface each with a plurality of bearing housing mount fasteners receiving holes therethrough; a first preassembled rotor cassette having a rotor shaft therein and having a predetermined rotor cassette bottom portion shape from a first frame portion slot in a first frame portion, wherein said first frame portion slot has a bottom portion having said predetermined rotor cassette bottom portion shape and is configured to receive therein and support from below said first preassembled rotor cassette; and a second preassembled rotor cassette comprising; a. a rotor shaft; b. a first side bearing housing mount; C. a second side bearing housing mount; d. a rotor; e. a first side bearing; and f. a second side bearing; said second preassembled rotor cassette being configured to be interchangeable with said first preassembled rotor cassette by being capable of being lowered into said first frame portion slot and said second frame portion slot in an absence of said first preassembled rotor cassette; and a plurality of bearing housing mount fasteners configured to be inserted through said plurality of bearing housing mount fasteners receiving holes to retain said second preassembled rotor cassette in said first frame portion slot.

12 . The continuous track propelled horizontal grinder of claim 11 wherein said first preassembled rotor cassette comprises a lower rotor portion and an upper attachment portion.

13 . The continuous track propelled horizontal grinder of claim 12 wherein said upper attachment portion further comprises a first side bearing housing mount with parallel sides configured to allow said lower rotor portion to slide down through first frame portion slot and be engaged and supported from below by a frame structure at a bottom portion of said first frame portion slot.

14 . The continuous track propelled horizontal grinder of claim 13 further comprising a plurality of holes through said upper attachment portion to receive said plurality of bearing housing mount fasteners when being used to retain said second preassembled rotor cassette in said first frame portion slot.

15 . A horizontal grinding system comprising:
a first frame portion with a first frame portion slot therein; a second frame portion with a second frame portion slot therein and with a parallel relationship with said first frame portion; said first frame portion and said second frame portion being coupled to a third frame portion configured to support an internal combustion engine having a horsepower characteristic in excess of eight hundred horse power; said first frame portion having a feed end frame to cassette slot defining surface and output end frame to cassette slot defining surface each with a plurality of bearing housing mount fasteners receiving holes therethrough; a rotor cassette sized and configured to fit into each of said first frame portion slot and second frame portion slot and span between said firs
