Harvesters TRIZ Cases

A harvesting reel assembly uses an adjustable non-circular cam track to pivot tine bars relative to the central shaft.

A transport vehicle chassis with a pivotable front section and coordinated balancer axle.

Intermediate transport belts guide plant stems through the recovery zone, preventing accumulation and jamming between conveying and spreading units.

Inclined ramp members guide foreign objects to impact a sensing surface with increased force for accurate detection.

A picking roller bearing device uses a removable disc component to enable extraction of internal parts without full disassembly.

Lagged cutting segments reduce impact and force peaks, extending working life of the chopping module.

Replacing rigid chains with a synthetic loop-wound belt and flexible combs eliminates operator safety risks while reducing maintenance needs.

A variable displacement pump electronically adjusts hydraulic flow to drive a cleaning fan without mechanical throttling valves.

A hingeable reel finger assembly pivots at the center of a split harvesting reel to direct crop material away from the central support structure.

Alternating blade segments on the cylindrical roller reduce wet material clogging while protecting conveyor belts from premature wear.

A sensor device determines crop stalk diameter before the picking gap to enable real-time width adjustment.

Use Growing Degree Day calculations to predict peak fatty acid content, preventing seed shattering while maximizing oil yield.

A translatable drive roller compensates for diagonal stresses caused by float arm flexing, maintaining proper belt alignment.

Blower airflows channel kernels from sheller plates to the rear auger, preventing loss through plate meatus.

Genetic reduction of plant height reduces lodging risk during extended field retention for natural kernel dry-down.

Single-piece cast stalk roll merges cutting edges and reduced diameter spline sections to eliminate assembly costs and prevent loosening during harvesting.

Segmented belt guides with smooth transitions reduce wear on endless belts by accommodating ground contours without underlaps.
