Planting TRIZ Cases
- Adjustable Depth Controller for Row Unit Planters
An adjustable depth controller pivots gauge wheel arms via a rocker arm and polymeric bushing to maintain precise planting depth across varying soil conditions.
- Seed Meter Monitoring System for Skip and Double Detection
Optical seed meter monitoring system uses light sensors and video cameras to detect empty cells and multiple seeds, eliminating skips and doubles.
- Elastic Press Wheel for Seeder Furrow Guidance
An elastic press wheel resolves soil sticking and deformation issues by using flexible tire structures for precise seed placement.
- Adjustable Fertilizer Application Implement with Swing Arm Actuator
Pivotal swing arm and adjustable actuator control disc depth, maintaining consistent fertilizer placement across varying soil conditions.
- Segmented Agricultural Wheel Body Design for Stress Reduction
Two separate flanges form a wheel body that maintains mechanical resistance while reducing mass and tire unseating risks.
- Seed Opener Singulation Tube Nested Within Pneumatic Passage
Nesting a singulation tube inside a pneumatic passage prevents airflow interference, ensuring accurate seed placement during simultaneous delivery.
- Ammonia Gas Delivery Tube With Expansion Nozzle
An expansion chamber in the discharge nozzle reduces gas velocity to prevent freezing while directing ammonia onto furrow walls.
