Design and development of a corn harvester
2001
Anon.
The corn harvester was developed to reduce high labor costs in harvesting corn. BPRE [Bureau of Postharvest Research and Extension] developed several prototypes in its pursuit of a working model adaptable to local conditions. There were several technical problems encountered during the development and these were addressed in succeeding prototypes. There were several configurations that could be made of the corn harvester for the manufacturer to decide: the tractor-mounted; the self-propelled; and the trailing type. The self-propelled type is the most common in use abroad but it is more expensive. Using a tractor-mounted model will tie-up the tractor to harvesting operations and is limited to single row, but cost is cheaper. The trailing type model could have up to four-row models but occupies big turning space. It is not commonly used nowadays. The study shows that the best and simplest design is the self-propelled two-row picker. Considering a combine would be too complicated to manufacture locally and is unsuitable under local conditions because the corn is harvested at high moisture (especially in South Cotabato, Philippines) and not suitable for immediate shelling. The performance results of the various prototypes are presented and discussed
