Description
APERFEIÇOAMENTO INTRODUZIDO EM FLUXÔMETRO PARA BICOS DE PULVERIZAÇÃO AGRÍCOLA IMPROVEMENT INTRODUCED IN FLOWOMETER FOR AGRICULTURAL SPRAYING NOZZLES
Campo da invenção Field of invention
[001] O presente modelo de utilidade se refere a um aperfeiçoamento introduzido num aparelho que é destinado a ser empregado na agricultura, mais particularmente nas lavouras, tendo a função de medir a vazão de bicos de pulverização de produtos agrícolas, podendo-se assim constatar as suas condições de operação, e possíveis necessidades de manutenção, regulagem ou troca, visando o seu melhor funcionamento. [001] The present utility model refers to an improvement introduced in a device that is intended to be used in agriculture, more particularly in crops, having the function of measuring the flow of spray nozzles for agricultural products, thus being able to verify its operating conditions, and possible needs for maintenance, adjustment or replacement, aiming at its better functioning.
Estado da técnica State of the art
[002] Sabe-se que na atividade agrícola, uma das tarefas mais importantes é a aplicação de produtos agrícolas, os quais são disponibilizados, em sua grande maioria, na forma de produtos líquidos, os quais são pulverizados por meio de máquinas sobre a lavoura em diferentes etapas do seu desenvolvimento. [002] It is known that in agricultural activity, one of the most important tasks is the application of agricultural products, which are available, in the vast majority, in the form of liquid products, which are sprayed by means of machinery on the crop. at different stages of its development.
[003] Com o aperfeiçoamento das tecnologias, chegou-se ao desenvolvimento de grandes máquinas, capazes de cobrir grandes áreas de lavoura, e portanto, podendo transportar e aplicar grandes quantidades de defensivos, fertilizantes foliares e adjuvantes, e isto, empregando um operador. Inicialmente, as referidas máquinas são projetadas para oferecer o máximo rendimento e aproveitamento do material pulverizado, garantindo que a mesma quantidade de material seja pulverizada através de todos os bicos que estejam em operação no momento, pelo equipamento, e que também haja constância no fluxo de material pulverizado ao longo de um período de tempo, o que otimiza o aproveitamento desse material. No entanto, a prática revela que algumas condições interferem no correto funcionamento dos bicos pulverizadores, tal como desgastes, defeitos de fabricação ou causados no momento da sua montagem, e até mesmo variações na constituição do material pulverizado, o
que faz com que, frequentemente, resulte no fato de que um ou mais bicos pulverizadores - de uma mesma máquina ou de variadas máquinas - operem de forma irregular, o que pode ser caracterizado pela liberação de uma menor quantidade de material sobre uma área, ou o seu contrário, o qual seria uma liberação excessiva de material sobre uma área. Sendo ambas as situações altamente indesejáveis, já que uma menor liberação de material resulta numa deficiência quanto ao resultado pretendido, enquanto que, a maior liberação de material pode ter consequências mais graves, principalmente quando se trata de produtos tóxicos, além de que, nesses casos, há um considerável prejuízo económico, o que pode tomar grandes proporções, já que essas operações cobrem grandes áreas, e assim, são pulverizados milhares de litros de defensivos, de modo que, uma pequena porcentagem de variação na quantidade de material pulverizado, pode representar uma grande quantidade de desperdício ao final da operação. Bem como, a aplicação excessiva de produtos agrícolas numa determinada área pode trazer prejuízos ambientais. [003] With the improvement of technologies, it was developed the development of large machines, capable of covering large areas of crops, and therefore, being able to transport and apply large amounts of pesticides, foliar fertilizers and adjuvants, and this, employing an operator. Initially, these machines are designed to offer maximum performance and use of the sprayed material, ensuring that the same amount of material is sprayed through all nozzles that are in operation at the moment, by the equipment, and that there is also a constant flow of water. sprayed material over a period of time, which optimizes the use of this material. However, practice reveals that some conditions interfere with the correct operation of the spray nozzles, such as wear, manufacturing defects or caused at the time of assembly, and even variations in the composition of the sprayed material, the which often results in the fact that one or more spray nozzles - from the same machine or from different machines - operate irregularly, which can be characterized by the release of a smaller amount of material over an area, or its opposite, which would be an excessive release of material over an area. Both situations being highly undesirable, since a lower release of material results in a deficiency in the desired result, while the greater release of material can have more serious consequences, especially when it comes to toxic products, besides, in these cases , there is a considerable economic loss, which can take on large proportions, since these operations cover large areas, and thus thousands of liters of pesticides are sprayed, so that a small percentage of variation in the amount of sprayed material can represent a large amount of waste at the end of the operation. As well as, the excessive application of agricultural products in a given area can bring environmental damage.
[004] Dito isto, é importante destacar que, observando -se estas adversidades, adotou-se realizar a medição do fluxo dos bicos de pulverização, averiguando- se assim se os mesmo se encontram operando dentro de uma faixa de tolerância. Sendo que, esta operação de medição é realizada, na sua forma mais básica, posicionando-se um copo medidor sob o bico pulverizador - em operação - durante um período de tempo pré determinado, e em seguida, calculando-se a relação litro/minuto de material liberado naquele bico, definindo- se assim se o referido bico se encontra operando normalmente ou se necessita de manutenção ou substituição por bicos adequados. Sendo que, neste modo de operação, necessita-se empregar dois colaboradores: sendo um para manusear o copo de medida, e outro para anotar os dados; destacando-se o fato de que esses dados ainda necessitam ser calculados posteriormente para determinar-se a vazão de cada bico.
[005] Com o objetivo de tornar mais prática e precisa essa operação, desenvolveram- se alguns equipamentos dedicados, sendo que, um dos modelos conhecidos compreende um copo de medida que é usado em conjunto com um aparelho telefónico celular - smartphone - e, sendo que, o copo de medida possui um suporte para o celular, cuja câmera é apontada para o copo; um aplicativo realiza a leitura da medida no copo, e gera um relatório; esse equipamento é pouco prático e de pouca precisão, o aparelho celular pode ser molhado facilmente, o que pode danificá-lo. Além disso, para que o aparelho funcione de forma confiável, é necessário que a câmera do aparelho celular seja de ótima qualidade, do contrário, o resultado pode não oferecer a precisão necessária. [004] Having said that, it is important to highlight that, observing these adversities, it was adopted to measure the flow of the spray nozzles, thus verifying if they are operating within a tolerance range. Since this measurement operation is performed, in its most basic form, by placing a measuring cup under the spray nozzle - in operation - for a predetermined period of time, and then calculating the liter / minute ratio of material released in that nozzle, thus defining whether said nozzle is operating normally or if it needs maintenance or replacement with suitable nozzles. Since, in this mode of operation, it is necessary to employ two collaborators: one to handle the measuring cup, and the other to record the data; highlighting the fact that these data still need to be calculated later to determine the flow of each nozzle. [005] In order to make this operation more practical and precise, some dedicated equipment has been developed, one of the known models comprising a measuring cup that is used in conjunction with a cellular telephone device - smartphone - and, being that the measuring cup has a holder for the cell phone, whose camera is pointed at the cup; an application performs the measurement reading on the cup, and generates a report; this equipment is impractical and of little precision, the cell phone can get wet easily, which can damage it. In addition, for the device to work reliably, it is necessary that the camera of the cell phone is of excellent quality, otherwise the result may not provide the necessary precision.
[006] Outra solução nessa área, compreende um recipiente no qual é acoplada uma unidade digital, que por sua vez é dotada de sensores, sendo que, a unidade digital mede o tempo que leva para que o recipiente atinja o seu nível de medição, exibindo o resultado num display, que assim pode ser anotado manualmente. No entanto, esse modelo também apresenta seus inconvenientes, sendo um deles o fato de que os sensores podem ser atingidos por respingos, apresentando imprecisão na leitura; e os dados gerados são acessados apenas por meio da visualização do seu display. Além de que, também são necessárias duas pessoas pra realizar a operação, uma anotando e a outra medindo com o aparelho. [006] Another solution in this area, comprises a container in which a digital unit is attached, which in turn is equipped with sensors, and the digital unit measures the time it takes for the container to reach its measurement level, displaying the result on a display, which can then be annotated manually. However, this model also has its drawbacks, one of which is the fact that the sensors can be hit by spatter, presenting inaccuracy in reading; and the data generated is accessed only through the visualization of its display. In addition, two people are also needed to perform the operation, one taking notes and the other measuring with the device.
