Reverse-Rotation Walk-Behind Local-Ground Harvester
Purpose
Gather suitable shallow mineral earth near a bounded test area while keeping collection, water addition, and discharge within one compact research platform.
Operating concept
A guarded ground-engaging rotor turns opposite intended travel, lifting loose mineral material into a screened transfer throat; a separate water path wets the accepted fraction before a forward or side discharge stage.
Key assemblies
guarded reverse-rotation rotor; adjustable depth/skid shoes; debris grate; screened throat; water manifold; metering gate; mixing/discharge chamber; traction and dead-man controls
Operating sequence
document and inspect source → engage shallow collection rotor → reject roots/rocks/trash → meter accepted mineral feed → add water downstream → discharge to test hose, tray, or receiver → stop, isolate, and purge
Instrumentation
material-source record; feed-rate indication; jam/overload status
Safeguards
guard exposed motion; reject debris before metering; provide emergency stop and lockout points
Failure modes and mitigations
rotor kickback or entanglement; unstable travel on slope; oversize entry; dust before wetting; soil disturbance and biological transport
Variants
self-propelled wheeled; tracked low-ground-pressure; electric tethered; battery research unit; receiver-only version without discharge
Validation gates
source documentation; debris and contamination screening; guarding/stability review; repeatable feed trial
Claim boundary
CLAIM BOUNDARY: No certified design, validated recipe, performance guarantee, regulatory approval, or authorization for uncontrolled-fire use is represented.
Unverified concept for qualified research. Not certified equipment, not a validated formula, not fabrication instructions, and not authorization for active-fire use. Individual conventional components are not claimed as separately invented.
