Encanteirador-depositor de fertilizantes mineral e orgânico para tratores de baixa potência

Abstract

Family Farming has a relevant importance in the production of food in a sustainable way, contributing significantly to the generation of work and income, as well as in the containment of the rural exodus. The objective of the present work was to design, construct and test an equipment to conform planting beds and deposit mineral and organic fertilizers, in the solid state, with maximum power requirement in the tractor engine of 25kW. The methodology used is based on the project methodology of the Phase Model, in this study the preliminary project with adaptations was used. The preliminary design, as well as the construction and testing of the prototype, were based on the work developed by Custódio (2015), which addresses the design of a mechanized system capable of conform planting beds, and deposit fertilizer. The tests as to the application rate and uniformity of distribution of the fertilizers allowed to determine the best speeds and transmission settings for each fertilizer, soil types and plant species, with an allowable variation coefficient. The prototype provided the conformation of planting beds with height up to 0,34m and 1.10m working width.
