Claims
- 1. An improved apparatus for mixing and aerating a windrow of material comprising:
- a. a frame having a front, a rear, and first and second opposing sides;
- b. a plurality of wheels rotatably connected to the frame;
- c. means for driving at least one of said plurality of wheels;
- d. means for raising and lowering said frame relative to each said wheel;
- e. an elongate cylindrical drum journaled transversely in the frame;
- f. means drivably connected to the drum for rotating the drum;
- g. a cab mounted on said frame, said cab being operable between a raised position and a lowered position;
- h. a fifth-wheel member pivotably connected to the first side of said frame, the fifth-wheel member having a retracted position, an intermediate position for supporting the first frame side at a first height above an underlying surface, and an extended position for supporting the first frame side at a second height above an underlying surface; and
- i. a dolly assembly pivotably connected to the second side of said frame, the dolly assembly having a retracted position, an intermediate position for supporting the second frame side at a first height above an underlying surface, and an extended position for supporting the second frame side at a second height above an underlying surface.
- 2. An improved compost apparatus according to claim 1 wherein the drum including means for generating a compost entraining air stream when the drum is rotated, the compost entraining air stream having a sufficient velocity for entraining substantially all of said composting material therein for mixing and aerating the windrow of composting material.
- 3. An improved compost apparatus according to claim 1 wherein the dolly assembly includes a frame and at least one wheel rotatably connected to said frame.
- 4. An improved compost apparatus according to claim 1 wherein the dolly assembly includes a frame and at least one wheel removably connected to said frame.
- 5. An improved compost apparatus according to claim 1 wherein said wheel driving means comprises:
- a hydraulic motor drivingly connected to at least one of said plurality of wheels;
- a hydraulic pump operatively connected to said hydraulic motor; and
- drive control means communicating with said hydraulic pump.
- 6. An improved compost apparatus according to claim 1 wherein said drum driving means comprises a hydraulic pump and a hydraulic motor operatively connected thereto.
- 7. An improved compost apparatus according to claim 1 further comprising an air stream containing chamber including a transverse top wall disposed above said drum, and a pair of opposed sidewalls joined at their respective upper ends to opposite ends of said top wall, each said sidewall having an angled upper sidewall portion extending downwardly and outwardly from said top wall and a lower sidewall portion extending substantially vertically downwardly from said angled upper portion.
- 8. An improved compost apparatus according to claim 7 wherein said drum is disposed between said opposed sidewall lower portions.
- 9. An improved compost apparatus according to claim 1 wherein respective first and second drum portions are interlockingly engaged with said respective first and second opposing frame sides and adapted for resisting a force acting to spread said respective first and second frame sides.
- 10. An improved compost apparatus according to claim 9 which further comprises first and second thrust bearings mounted on the drum outboard of the respective first and second opposing frame sides.
