Desenvolvimento de um mecanismo alternativo para distribuição de fertilizantes e corretivos sólidos

Abstract

The objective of this work was the development of an alternative mechanism for the distribution of fertilizers and solid correctives, having as basic operating principle the use of a horizontal rotor with variable angular velocity and the presence of deflectors with adjustable vertical and horizontal angles, aiming at a greater uniformity of distribution range. The project was divided into three stages: informational design, conceptual design and preliminary design. In the three phases of the project were carried out, respectively, the search for information regarding the available fertilizer distributors in the market, identifying their positive and negative characteristics; the definition of the characteristics of the developed equipment, including its operation and operation; Finally, the dimensional parameters and geometry of each component of the assembly were determined so that the mechanism presented extensive versatility and ease of handling. The developed mechanism, in general, presents significant potential for advances in the technology of application of fertilizers and solid correctives, due to the solutions that the equipment presents to the current problems faced in the field with the distributors present in the market. The reduced prototype was built with feasibility and presented all the essential characteristics of the final product, it will simplify the accomplishment of the inherent project evaluations, which through CFD (Computational Fluid Dynamics) methods would present a high degree of difficulty.
