Projeto conceitual de uma semeadora-adubadora pneumática de precisão para plantio direto de cebola e cenoura

Abstract

This paper has as objective to approach the development of a conceptual design of a pneumatic precision seeder for a no-till onion and carrot farming system, with the use directed to small farmers, those who have in the planting of these cultures one of the main income sources. The project aims to design an equipment capable of being pulled by a micro tractor, providing precision and uniformity in planting, replacing the conventional forms that require great physical effort and uncomfortable ergonomic conditions for farmers. The design and selection of the equipment components followed a methodology based primarily on supporting research, addressed as bibliographic review. Using CAD software, it was possible to develop an easy-tofabricate structure, focused on simplicity of maintenance, low cost, and robustness. The developed seeder has as main features: soil opening system and furrowing mechanisms for fertilizer and seed deposition, fertilizer dosing system, pneumatic seed metering device, and compactor wheel.
