Threshers TRIZ Cases
- Tangential Transition Housing for Combine Harvester Threshing
Curved transition housing walls guide crop flow to reduce power consumption and prevent material lodgment in combine harvesters.
- Power-Assisted Corn Kernel Remover with Pneumatic Piston and Flexible Cutter
A pneumatic piston pushes corn cobs through a flexible spring steel annular cutter, separating kernels while accommodating varying cob diameters.
- Reciprocating Sieve Hanger Mount for Agricultural Harvester
Friction grip connections using pressed wood blocks replace mechanical fasteners to eliminate weld fatigue under cyclical loading.
- Combine Harvester Airflow Segmentation for Cleaning Loss Reduction
Segmenting airflow via a return floor outlet removes chaff early, preventing counter-flow at the upper sieve that causes grain discharge losses.
- Sieve Assembly Integrating Clean Grain Pan for Harvester
Merges sieve and clean grain pan into one assembly to reduce device complexity and system weight while maintaining structural rigidity.
- Hydraulic Vane Actuation for Rotary Thresher Crop Flow Control
Hydraulically powered linear actuators adjust rotor cage vane angles to regulate crop flow in rotary threshers.
- Adjustable Sieve Lamellae for Combine Harvester Grain Separation
Varying lamellae angles and positions creates a gradient of screen openings that reduces grain loss while maintaining high separation purity.
- Concave Adjustment and Release Unit for Combine Harvester Threshing System
A spring arrangement in series with an actuator buffers excessive force to release the concave from the threshing rotor.
- Linear Side-Shake Control for Combine Sieve
Dynamic actuator mounting eliminates arc motion, reducing vibrational stress and allowing larger sieves.
- Axial Separator Guide Element Adjustment
Position-changeable guide element adapts to crop moisture, preventing uneven residue distribution.
- Air Guide Element Deflects Flow for Combine Harvester Cleaning
A concave air guide element redirects horizontal airflow to separate grain from chaff by eliminating turbulence at the drop step.
- Rear Accessible Sieve Retainer for Harvesters
A rear-accessible sieve retainer uses detent elements to lock and unlock without disassembly, enabling quick component replacement.
- Harvester Louver Wire Retention via Segmented Bar Pockets
Segmented bar pockets pivot louver wires to simplify repair and lower manufacturing costs in harvester cleaning systems.
- Combine Harvester Return Conveyor Belt for Grain Loss Reduction
Continuously circulating return conveyor belt prevents grain accumulation and blockages during cleaning, reducing substance loss on uneven terrain.
