CONDUTOR DE SEMENTES A VÁCUO CAMPO DA INVENÇÃO VACUUM SEED CONDUCTOR FIELD OF THE INVENTION
[01] A presente invenção descreve um sistema de engrenagens aplicado no dosador e condutor de sementes a vácuo. Mais especificamente compreende um sistema de engrenagens, de vários tamanhos, que alojam e transportam as sementes desde o sistema seletor até o sulco da semeadura através de movimentos sincrônicos em sentidos opostos que conduzem as sementes de maneira uniforme. Assim, esta nova forma construtiva permite aumentar a velocidade de deslocamento das sementes de forma a compensar o deslocamento do trator, não sofrendo com ação da trepidação da linha e mantendo o distanciamento correto até o sulco de semeadura. [01] The present invention describes a gear system applied to the vacuum feeder and seed driver. More specifically, it comprises a system of gears, of various sizes, which house and transport the seeds from the selector system to the sowing groove through synchronous movements in opposite directions that conduct the seeds in a uniform manner. Thus, this new constructive form allows to increase the speed of displacement of the seeds in order to compensate the displacement of the tractor, not suffering from the action of the trepidation of the line and maintaining the correct distance until the sowing furrow.
ANTECEDENTES DA INVENÇÃO BACKGROUND OF THE INVENTION
[02] No plantio de sementes, é sabido que a qualidade e a distribuição das sementes no solo são fundamentais para um bom desempenho, estima-se que para cada percentual de falha no plantio (cova sem semente) ou para cada percentual de “duplo” no plantio (duas sementes por cova) tem-se uma perda de 3,3% em produtividade. [02] When planting seeds, it is known that the quality and distribution of seeds in the soil are fundamental for good performance, it is estimated that for each percentage of failure in planting (seedless pit) or for each percentage of “double ”When planting (two seeds per hole) there is a loss of 3.3% in productivity.
[03] Além disso, existe uma perda maior pelo distanciamento irregular das sementes, ou seja, o coeficiente de variação (CV) do distanciamento entre os grãos, proporcionando uma perda de produtividade de 1 ,5 a 3 sacos por hectare para cada 10% de variação do coeficiente de variação (CV). [03] In addition, there is a greater loss due to the irregular spacing of the seeds, that is, the variation coefficient (CV) of the spacing between the grains, providing a productivity loss of 1, 5 to 3 bags per hectare for every 10% of variation of the coefficient of variation (CV).
[04] Atualmente, as semeadoras para o plantio compreendem um tubo condutor de sementes desde o sistema seletor ate o sulco da semeadura. A semente é transportada do tubo condutor para dentro do sistema, caindo em queda livre de uma altura média de setecentos milímetros até o sulco de semeadura, esse sistema além de gerar uma desuniformidade na distribuição e o alto coeficiente de variação em função da queda desordenada da semente, não apresenta nenhum dispositivo regulador para controlar a deposição da semente e, ainda, pode apresentar sensores no centro do tubo condutor que impedem a semente de deslizar retilineamente no sulco de semeadura, desuniformizando sua deposição. [04] Currently, sowing machines for planting comprise a seed conducting tube from the selector system to the sowing groove. The seed is transported from the conductive tube into the system, falling in free fall from an average height of seven hundred millimeters to the sowing groove, this system not only generates an uneven distribution and the high coefficient of variation due to the disorderly fall of the seed, it does not have any regulating device to control the deposition of the seed and it can also have sensors in the center of the conductive tube that prevent the seed from sliding straight into the sowing groove, making its deposition uneven.
[05] Estes sistemas trabalham com variação do coeficiente de variação (CV) de 30% a 80%, tendo-se perdas de produtividade de 4,5 até 25 sacos por hectare. [05] These systems work with variation coefficient of variation (CV) from 30% to 80%, with productivity losses of 4.5 to 25 bags per hectare.
[06] O documento WO2015168759, do mesmo titular, descreve uma base estrutural circular dotada de tampa e base vertical angulada dotada de tampa, na parte superior da base descreve uma caixa de sementes, uma turbina de vácuo e um disco de corte, sendo o sistema acionado por uma barra e engrenagem que rotaciona no sentido horário o disco seletor transmitindo o movimento para as engrenagens vazadas dotadas de espaçamentos que direcionam as sementes até a rampa de soltura, reduzindo o coeficiente de variação da semente na linha de semeadura. [06] The document WO2015168759, of the same holder, describes a circular structural base with lid and angled vertical base with lid, in the upper part of the base it describes a seed box, a vacuum turbine and a cutting disc, being the system driven by a bar and gear that rotates the selector disk clockwise, transmitting the movement to the hollow gears with spacings that direct the seeds to the release ramp, reducing the seed variation coefficient in the sowing line.
[07] Nesse sentido, buscando melhorar e aperfeiçoar o sistema dosador e condutor de sementes a vácuo, o presente titular, desenvolveu um sistema de engrenagens que permite aumentar a velocidade de deslocamento das sementes de forma a compensar o deslocamento do trator, não sofrendo com ação da trepidação da linha e mantendo o distanciamento correto até o sulco de semeadura. [07] In this sense, seeking to improve and perfect the vacuum seed metering and conductor system, the present holder has developed a gear system that allows increasing the seed displacement speed in order to compensate the tractor displacement, without suffering from line shake action and maintaining the correct distance to the sowing furrow.
[08] Desta forma, é objeto da presente invenção, um sistema de engrenagens aplicado no dosador e condutor de sementes a vácuo que compreende um sistema de engrenagens que alojam e transportam as sementes desde o sistema seletor até o sulco da semeadura através de movimentos sincrônicos em sentidos opostos que conduzem as sementes de maneira uniforme.
