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.
Claims20
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.

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.

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 first frame portion and said second frame portion;
- and
- a pivoting clamshell cassette covering upper portion;
- pivotally coupled to one of said first frame portion and second frame portion, where said pivoting clamshell cassette covering upper portion tends to help retain said rotor cassette in an operating configuration when said pivoting clamshell cassette covering upper portion is lowered to reduce movement of said rotor cassette in said first frame portion slot and said second frame portion slot.
