Farm Hack : Auto-Rewind Spray System Mounted on Electric Trike

A Little Wisdom Helps You Become Smarter !

This video showcases a portable high-pressure crop sprayer in action, designed to streamline pesticide application in wheat fields. The system is mounted on an electric tricycle for mobility, featuring a large chemical tank (200-500L capacity) and a diesel-powered pump that pressurizes liquid to 10-40 MPa. A retractable 100-meter reinforced hose, stored on an auto-rewind reel, connects to a handheld spray wand with adjustable nozzles. Farmers can walk the hose deep into fields while the trike remains stationary at the edge, enabling precise spraying across 2-3 acres without repositioning machinery.

How It Works:
The diesel engine drives a piston pump to pressurize the chemical mix, forcing it through the hose. The wand’s nozzle atomizes the liquid into fine droplets, improving crop coverage while reducing runoff. The spring-loaded hose reel automatically retracts the line post-use, minimizing tangles.

Pros:

Efficiency: Covers 3x faster than backpack sprayers, ideal for midsized farms.

Terrain Adaptability: Navigates ditches or slopes where tractors can’t go.

Cost-Effective: 20-30% less chemical waste vs. traditional methods.

Cons:

Noise/Pollution: Diesel models emit 85-90 dB noise and exhaust fumes.

Maintenance: Hoses degrade after 200-300 hours of abrasive field contact.

Labor Intensity: Still requires manual wand operation under sun exposure.

Best For: Small to medium farms prioritizing affordability over automation. Eco-conscious buyers can opt for electric pump variants (solar-compatible) to reduce carbon footprints.
