Family farming in Brazil is responsible for the country's food security, ensuring most of the food consumed by Brazilians. However, the agricultural machinery and equipment industry has not been dedicated to providing innovations to this sector, focusing mainly on supplying large agribusiness properties with the most advanced technology equipment. Thus, the introduction of new technological solutions regarding agricultural machines for family farming is necessary. Considering the need to supply this branch of the Brazilian agricultural sector with new technologies, this study aimed to establish the design specifications of an autonomous electric vehicle that serves as a multifunction platform, which was primarily designed to remove weeds, mainly meeting the needs of family farmers. The product development methodology in its informational phase was applied to obtain and study these needs. As a result, 19 design specifications were established with their associated target values, allowing defining the physical and economic parameters that will be the basis for the development of the autonomous electric vehicle in its conceptual phase.

“…A metodologia fundamenta-se no Modelo de Fases, empregado na geração de produtos agrícolas como por exemplo, na estrutura funcional de uma semeadora de acionamento manual (STEFANELLO et al, 2014); na estrutura funcional de um encanteirador e depositor de fertilizantes (CUSTÓDIO et al, 2018); nas especificações para o projeto de um mecanismo aplicador de calor (SPAGNOLO et al, 2018) e no projeto conceitual de máquina para o controle de plantas espontâneas pela aplicação de calor de Spagnolo et al (2019).…”

A agricultura familiar é responsável por uma parcela importante da produção agrícola brasileira, entretanto possui dificuldades na aquisição de máquinas adequadas para suas necessidades. Em entrevistas com agricultores familiares do Rio Grande do Sul, foi detectada a necessidade de uma máquina capaz de conformar canteiros e depositar fertilizante orgânico. O objetivo do trabalho foi projetar a concepção de um sistema mecanizado capaz de conformar canteiros e depositar fertilizante orgânico com necessidade de potência de acionamento inferior a 25kW. Foi utilizada a metodologia de projeto do Modelo de Fases, que é dividida em quatro fases, compostas por diversas tarefas. Como resultado da aplicação da metodologia obteve-se quatro concepções, após aplicação da matriz de decisão das concepções, foi determinada uma concepção para o processo de otimização, obtendo-se posteriormente aquela considerada ideal para atender as necessidades dos agricultores. Palavras-chave: Projeto de máquinas; máquinas agrícolas; agricultura familiar.

“…The prototype of the heat-applicator machine composed of four rows of heat application was coupled to the tractor (Figure 1). The prototype was constructed according to the specifications determined by Spagnolo et al (2018) and the conceptual project proposed by Spagnolo et al (2019). FIGURE 1.…”

Heat-Applicator Machine for Weed Control

Pesticide environmental risks and increased weed resistance have encouraged studies for alternatives to herbicides. Among these are weed thermal control methods by controlled heat application machines. Thus, this study aimed to test a prototype of heat-applicator machine as a function of changes in gas pressure, travel speed, and tire traffic effect on plants. Then, three experimental factors were tested: gas pressure (98, 196, and 245 kPa), travel speed (0.56, 0.78, and 1.17 m s −1), and tire traffic effect on plants (with and without traffic). The results showed that tire traffic effect on plants and subsequent heat application had no effect on control rate. Weed control rates reached levels considered satisfactory using a heat application speed of 0.56 m s −1 associated with gas pressures of 245 or 196 kPa, as well as a heat application speed of 0.78 m s −1 associated with a gas pressure of 245 kPa. A total between 60.9 and 84.9 kg ha-1 liquefied petroleum gas was required for weed control of around 80%.
