Diseño y construcción de un prototipo mecatrónico cosechador de yuca para pequeños agricultores

Abstract

In this document we can verify the development of the technological device entitled "Design and construction of a mechatronic prototype cassava harvester for small farmers", it is intended for the technical, social and agricultural field. It is a system made up of a metallic structure composed of a lever mechanism assisted by an electric keypad, it also incorporates an electric wheel to move the prototype. This helps the operator to place the machine in the desired position and provides the necessary uprooting force to reduce physical effort. For the design of the machine, the standards of the Ecuadorian Institute of Standardization NTE INEN-ISO 7250-1 were taken into account, as well as the guide of good practices of safety and hygiene at work. The prototype was elaborated with mechanical and electrical components and materials that are easily accessible in the Ecuadorian market, focused on Latin American anthropometric measurements. For the mechanical design, static analysis of the elements was carried out through finite element simulations in Inventor 2022 software. For the design of the electrical control system, the programming that governs the behavior of the electric motor was implemented with the support of the Arduino IDE. With the controlled parameters the operator will be able to determine the position and orientation of the extraction claw that will allow him to perform the cassava harvesting activity in an ergonomic environment with respect to its vertical grip posture, in addition to being an easy to assemble prototype that allows free movement of the operator.
