Resumo: | The hydropneumatic sprayers transform the slurry into droplets by passing liquid under pressure through pressure nozzles. Following a strong current of air, drops splits again and carries up targets. There are few studies on inspection of these machines, especially the complexity of its operation. Thus, the objective was to propose simple and practical methodology for collecting data relating to the inspection of hydropneumatic sprayers. The proposed methodology was tested in thirty hydropneumatic sprayers used in the coffee plantations in the Alto Paranaíba – MG region. There was spray volume and index properties used in employing the method the volume of vegetation. There was also the volume of air produced by the fan sprayers in order to observe whether it was consistent with the value specified by the manufacturer. Constructed a vertical structure 3 m high to collect the pulverized in order to determine the volumetric distribution uniformity along the liquid sprayed plants. We used the chi square (χ2) to verify the adequacy of the sprayed vegetation volume. The average spray volume (581 L ha-1) was rated as medium. However, the index of average volume (59 L 1000-3) was considered high. The spray volumes need to be adjusted according to the different parts of the sprayed plants. It was concluded that the proposed methodology is feasible for the evaluation of hydropneumatic sprayers. |

Na sequência, uma forte corrente de ar fraciona novamente as gotas e as transporta até os alvos. São poucos os trabalhos sobre inspeção dessas máquinas, sobretudo pela complexidade do seu funcionamento. Objetivou-se, neste trabalho, propor método simples e prático para coleta de dados relativos à inspeção de pulverizadores hidropneumáticos. O método proposto foi testado em trinta pulverizadores hidropneumáticos, utilizados nas lavouras de café na região do Alto Paranaíba-MG. Verificou-se o volume e o índice de pulverização utilizado nas propriedades empregando-se o método do volume de vegetação. Verificou-se também o volume de ar produzido pelo ventilador dos pulverizadores, para observar se era condizente com o valor especificado pelo fabricante. Construiu-se uma estrutura vertical de 3 m de altura para coleta do líquido pulverizado, a fim de se determinar a uniformidade de distribuição volumétrica ao longo das plantas pulverizadas. Empregou-se o teste de qui-dradado (χ2) para a verificação da adequação do volume pulverizado ao volume vegetativo. O volume médio pulverizado (581 L ha-1) foi classificado como médio. Entretanto, o índice de volume médio (59 L 1000-3) foi considerado elevado. Os volumes pulverizados necessitam de adequações de acordo com as diferentes partes pulverizadas das plantas. Concluiu-se que o método proposto é factível para a avaliação de pulverizadores hidropneumáticos.Editora UFLA2015-02-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/ziphttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/772Coffee Science - ISSN 1984-3909; Vol. 10 No. 1 (2015); 76 - 82Coffee Science; Vol. 10 Núm. 1 (2015); 76 - 82Coffee Science; v. 10 n. 1 (2015); 76 - 821984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/772/pdf_161https://coffeescience.ufla.br/index.php/Coffeescience/article/view/772/1365Copyright (c) 2015 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessRuas, Renato Adriane AlvesSichoki, DiegoDezordi, Luciel RauniFilho, Alberto CarvalhoGod, Pedro Ivo Vieira Good2015-06-02T03:32:20Zoai:coffeescience.ufla.br:article/772Revistahttps://coffeescience.ufla.br/index.php/CoffeesciencePUBhttps://coffeescience.ufla.br/index.php/Coffeescience/oaicoffeescience@dag.ufla.br||coffeescience@dag.ufla.br|| alvaro-cozadi@hotmail.com1984-39091809-6875opendoar:2024-05-21T19:53:49.720356Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true |
