Threshers TRIZ Cases
- Dynamic Cover Plate for Combine Harvester Threshing
Segmented cover plates alter airflow characteristics to improve threshing efficiency for hard-to-thresh crops without swapping grate assemblies.
- Switchable Valve Suction System for Combine Harvester Dust Control
A switchable valve redirects suction airflow to clear deposits during idle periods.
- Combine Harvester Drum Contaminant Removal via Funnel Deflectors
Funnel-shaped crop deflectors on combine harvester drums redirect debris outward through centrifugal force.
- Removable Cover Plate for Uniform Grain Distribution in Harvester Threshing
Perforated removable cover plates restrict grain passage through the concave to ensure uniform distribution, reducing accumulation and waste on sloping grounds.
- Oblique Step Cover for Combine Harvester Crop Guidance
An oblique step in the harvester cover guides crops along a helicoidal path, resolving irregularities that hinder progression and increase power consumption.
- Torsion Axle Damping Impulse Loads in Concave Adjust Assembly
A torsion axle with resilient damping elements absorbs impulse loads between the drive and concave.
- Combine Harvester Cleaning Pan Damping Surface
A combine harvester cleaning pan uses a rubber damping surface to reduce grain bounce upon impact.
- Separator Rotor Mounting Component Weld Seam Geometry
Angled weld seam extensions on separator rotor mounting components absorb operational moments through asymmetric structural design.
- Free-rolling rotor cage reduces grain loss in combine harvesters
A free-rolling rotor cage rotates via threshed crop to enhance separation efficiency.
- Non-Circular Gear Sieve Drive for Combine Harvesters
A non-circular gear drive arrangement transforms constant rotation into linear upward sieve motion.
- Aggressive Grate for Combine Harvester Threshing
Disrupter walls on axial bars disrupt axial crop flow to increase threshing time and improve separation efficiency.
