Abstract
Abstract A machine having a continuous conveyer with a scoop at its forward end and a jet engine supplies hot air at 600* F. and 600 miles per hour to the conveyer. The hot air from the engine is directed back and forth through the dirt being conveyed and the conveyer approximately five times. Hydraulic motors and power cylinders are driven by the jet engine for moving the machine and raising and lowering the conveyer and scoop. A rototiller may be placed in proximity of the scoop for pulverizing the soil.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
166 words
A soil drying machine comprising, an elongated frame having a scoop at its forward end, a material conveyer on said frame extending from said scoop the substantial length of said frame, said material conveyer including openings for passing air therethrough, and said scoop adapted to engage the ground with said conveyer being above the ground, a pressurized hot air source, said frame incuding a series of alternating upwardly and downwardly extending walls for forming air flow passageways back and forth through said conveyer throughout its length, and said pressurized hot air source being connected to said air flow passageways, and an air outlet being provided at the rear end of said conveyer, and an enclosure wall extending over said conveyer and enclosure side walls extending to the ground below said conveyer, and said upwardly and downwardly extending walls cooperate with said enclosure walls and the ground to define said air flow passageways for directing said hot air back and forth through said conveyer and material thereon.
Claim 2
Dependent Claim
166 words
A soil drying machine comprising, an elongated frame having a scoop at its forward end, a material conveyer on said frame extending from said scoop the substantial length of said frame, said material conveyer including openings for passing air therethrough, and said scoop adapted to engage the ground with said conveyer being above the ground, a pressurized hot air source, said frame incuding a series of alternating upwardly and downwardly extending walls for forming air flow passageways back and forth through said conveyer throughout its length, and said pressurized hot air source being connected to said air flow passageways, and an air outlet being provided at the rear end of said conveyer, and an enclosure wall extending over said conveyer and enclosure side walls extending to the ground below said conveyer, and said upwardly and downwardly extending walls cooperate with said enclosure walls and the ground to define said air flow passageways for directing said hot air back and forth through said conveyer and material thereon.
Claim 3
Dependent Claim
18 words
The structure of claim 1 wherein said hot air source is further defined as being a jet engine.
Claim 4
Dependent Claim
34 words
The structure of claim 2 wherein said jet engine is operatively coupled to drive wheels for moving said machine and to said conveyer for moving said material from said scoop to an outlet openings.
Claim 5
Dependent Claim
21 words
The structure of claim 1 wherein said hot air source provides hot air at a temperature of at least 600* F.
Claim 6
Dependent Claim
19 words
The structure of claim 1 wherein said hot air source provides air moving at a speed of 500-700 m.p.h.
Claim 7
Dependent Claim
28 words
The structure of claim 1 wherein said hot air sources provides air at a temperature of at least 600* F. and moving at a speed of 500-700 m.p.h.
Claim 8
Dependent Claim
21 words
The structure of claim 1 wherein said hot air source is directed first through said conveyer at the forward end thereof.
Claim 9
Dependent Claim
28 words
The structure of claim 7 wherein said conveyer is endless and includes a series of longitudinally spaced apart flights whereby said air flow passageways are between said flights.
Claim 10
Dependent Claim
48 words
The structure of claim 8 wherein hot air in introduced into the side of said conveyer in a forward compartment and a series of compartment walls are provided between upper and lower conveyer flighting at distances equal to the longitudinal measurement of said flow passageways along said conveyer.
Claim 11
Dependent Claim
65 words
The structure of claim 1 wherein said frame includes support wheels at the front and rear ends, a pair of frame portions extend from the front and the rear end of said machine and are pivotally interconnected, said material conveyer is carried on said rear frame portion and a power cylinder is connected between said frame portions to raise and lower said scoop and conveyer.
