Automated Spike Weed Remover
Budget: $1,500 – $3,000 USD
I'm looking for a skilled metalworker and mechanical engineer to design and create a unique weed remover.
The tool should feature:
- Downward-facing spikes that rotate to capture weeds.
- A spring piston mechanism to pull up weeds above the spikes when a button is pressed.
- A foam grip for comfort.
- A medium-length handle (about 2 feet).
Ideal skills and experience:
- Proficiency in metal fabrication.
- Experience with mechanical design and spring piston systems.
- Ergonomic handle design expertise.
And these components
components 1. Engine + Power Transmission • Gasoline or Battery-Powered Engine ◦ Output: 2000 lb-ft torque ◦ Speed: 1000 RPM ◦ Lightweight aluminum housing for portability • Gearbox/Reduction Drive ◦ 2-stage planetary or bevel gear system ◦ Rated for 2000+ lb-ft torque ◦ Output shaft aligned to rotating spike hub 2. Spike Mechanism • Spike Hub Plate ◦ 6–10 inch diameter steel disc ◦ Precision bored for central shaft mounting • Spikes (10 total) ◦ Hardened carbon steel, 6–8 inches long ◦ Tapered conical shape or flat tines ◦ Welded or bolted into the hub plate • Bearing Assembly ◦ Ball or tapered roller bearings ◦ Sealed, greased housing ◦ Supports hub on rotating shaft 3. Spring-Loaded Piston Ejector • Piston Rod ◦ Hardened steel or chrome-plated shaft ◦ 1-inch diameter, 6–8 inch stroke • Spring ◦ Compression coil spring ◦ Rated to exert 600 lbs force • Trigger Mechanism ◦ Manual pull handle or thumb trigger ◦ Ratcheting or cam-lock spring preload and release • Piston Housing ◦ Heavy-duty tube or cylinder aligned under spike hub ◦ Mounted inside protective lower shroud 4. Frame & Housing • Main Shaft & Handle ◦ Hollow steel shaft with anti-vibration padding ◦ 1.5–2 inches diameter • Main Handle Grip ◦ Rubberized or foam-insulated for comfort and control ◦ Ergonomic T- or D-handle design • Upper Engine Mount ◦ Reinforced bracket for engine and gearbox ◦ Vibration-damping rubber bushings • Protective Guards ◦ Polycarbonate or sheet metal guards over spikes ◦ Debris shield around spring ejector 5. Controls • Throttle Trigger or Rotary Dial ◦ Mounted on handle ◦ Variable RPM control • Kill Switch ◦ Emergency stop ◦ Inline with throttle wiring • Spring Trigger ◦ Separate control for spring piston action ◦ Locking
