Diseño y construcción de una máquina picadora de desechos florícolas con capacidad de 100 kg/h para la Finca San Fernando Comunidad Santo Domingo N°1-cantón Cayambe

Abstract

The current work includes the planning and development of a machine to grind floricultural wastes in the San Fernando farm, Santo Domingo N°1 - Cayambe Canton, with the objective of producing organic fertilizer. Currently, floriculture in the Cayambe canton is growing due to the need to satisfy the market of roses nationally and internationally; the main problem of flower farms is the production of waste such as stems, leaves, and dehydrated or damaged flowers, which are waste generated in the processes of production, post-harvest and packaging of flowers. In order to satisfy the need, the different alternatives of agricultural waste chopping machines that could be used were investigated. As a first step, a selection matrix was generated, providing the best machine option such as the use of 3 K100 blades, blade holder, gasoline engine, structure, and transmission belts, input and output hoppers. The main criteria studied are: forces, bending moment, moment of inertia and centrifugal moment, turning radius, general mathematical relation defined between effort and deformation, selection of safety coefficient, bending and torsion, etc. The construction of the grinding machine is carried out to meet a capacity of 100 Kg/h with dry material. For the manufacture of the blades and the shaft, simulations were carried out in Solid Works software, taking into account the finite element analysis, Von Mises stresses, displacement diagram and deformation diagrams to determine their maximum values.
