Reel Parameters Adjustment during Mechanical Harvest of Rice in Cuban Conditions.

According to international experience, grain losses due to poor regulation of the reel have a significant weight (approximately between 33 and 73%) within the total losses attributable to the rice harvesters, being able to reach up to 23% of the total harvested product. The national practice of regulating the windlass during the mechanized harvesting of rice does not include the application of scientific principles that are established internationally in the theory of agricultural machinery. Consequently, it is necessary to carry out studies where these concepts are applied, to perfect the harvesting process, minimizing the losses attributable to poor regulation of this body of work. These conceptual models were applied and computerized programmed. As input data they were taken: the construction, exploitation and regulation parameters of the windlass of the combined Claas-Crop Tiger 30, used in production conditions (Agro industrial Grain Company of Amarillas locality, Matanzas province) and the properties of the harvested crop (Oriza sativa, variety "Reforma"). As a result, it was determined that, most of the requirements for good windmill exploitation are not met. Correction of exploitation and regulation parameters is proposed to minimize the losses attributable to the action of this body of work. [ABSTRACT FROM AUTHOR]
