Diseño y construcción de una pértiga de poda hidráulica manual para árboles frutales: sistema de transmisión de potencia y sistema telescópico.

Abstract

This project shows the design and construction of an Extension and Transmission system for a Hydraulic Pruning Pole. This project is a system component in conjunction with two additional components the cutting and hydraulic modules. A 5-stage process was used for the design: 1.-Product Definition, 2.-Conceptual Design, 3.-Component Calculation and Selection, 4.-Drawing, 5.-Construction and Assembly. An important tool used was the House of Quality Methodology, which was used to integrate the client's requirements and the engineering criteria. Two main design criteria were used for the calculations: Stability Theory and Fatigue Design. For the construction, AISI 304 Stainless Steel was used as the main material for resistance in outdoor conditions. For the manufacturing process of the stainless steel, machining technologies available in the country were used. The transmission prototype was made using the 3D printing process of Fused Deposition Modeling (FDM). Finally, a prototype was obtained with the following technical specifications: Extension capacity from 1.75 m to 2.50m. Transmission by roller chain with hydraulic actuator. Force amplification factor of 32. High resistance to outdoor conditions. Weight of Extension and Drive Component 2.3 kg. Total weight of Hydraulic Pole 5.3 kg.
