Optimización en eficiencia, ergonomía y seguridad del prototipo de trilladora portátil de quinua con acople a motor de combustión interna de motocultor YTO DF 15Y para la Empresa COPROBICH

Abstract

In this technical project type degree work, the optimization process is shown in efficiency, ergonomics and safety of the prototype of portable quinoa thresher with coupling to YTO DF 15Y waking tiller of internal combustion engine for COPROBICH company which presented several deficiencies during its operation such as grain waste, an unacceptable grain cleaning degree, insufficient production, absence of safety and bag hooks, a high vibration that moved the machine from its operation place and finally there were no maintenance and user manuals. Based on these shortcomings, the available information was analyzed, determining the strategy that will be applied to the thresher prototype to optimize it, such as the implementation of a beater cylinder, redesign of the cleaning shoe, calibration of the threshing cylinder and straw walker, implementation of safety elements (sheave guards and belts) and ergonomics (hooks for bags), achieving a 90.57% efficiency of collected grain; 3.47% impurities (material other than grain) in the collected material, a production of 42.79 kg/h (kilograms/hour) and reduce vibrations produced during machine operation between 16.66% - 37.91%. Finally, handbooks for the maintenance and use of the thresher prototype were undertaken, in order to transmit the necessary information to the operator and ensure its good condition.
