SISTEMA DOSADOR E TRANSPORTADOR DE SEMENTES A VÁCUO APLICADO EM SEMEADORA CAMPO DA INVENÇÃO  VACUUM SEED DOSER AND CARRIER SYSTEM APPLIED IN SOWING FIELD OF THE INVENTION
[01] A presente invenção descreve um sistema dosador e transportador de sementes a vácuo aplicado em semeadora. Mais especificamente compreende um dosador a vácuo dotado por um sistema de transmissão que apresenta um conjunto de correntes que permitem a movimentação de todo o sistema dosador de forma a melhorar e facilitar o sincronismo de acionamento. Além disso, o sistema é dotado por uma placa guia que tem por objetivo direcionar as sementes até a correia taliscada de forma a manter a distancia correta e aumentar a precisão no distanciamento entre as sementes no solo. Esta nova forma construtiva reduz o número de peças, tornando o produto compacto, simplificado e protegido das intempéries.  [01] The present invention describes a vacuum seed feeder and conveyor system applied to a seeder. More specifically, it comprises a vacuum feeder provided with a transmission system which has a set of chains that allow the entire feeder system to move in order to improve and facilitate the drive timing. In addition, the system is equipped with a guide plate that aims to direct the seeds to the taliscan belt in order to maintain the correct distance and increase the precision in the distance between the seeds in the soil. This new construction reduces the number of parts, making the product compact, simplified and protected from the weather.
[02] Além disso, esta construtividade permite que as sementes sejam conduzidas do sistema seletor até a linha de semeadura no solo, limitando a aceleração da gravidade na semente e impedindo sua deposição imediata e desuniforme na linha de semeadura.  [02] In addition, this constructivity allows seeds to be carried from the selector system to the soil sowing line, limiting the acceleration of gravity in the seed and preventing their immediate and uneven deposition on the sowing line.
ANTECEDENTES DA INVENÇÃO  BACKGROUND OF THE INVENTION
[03] 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.  [03] In seed planting, it is well known that seed quality and distribution in the soil are fundamental for good performance, it is estimated that for each percentage of planting failure (pit without seed) or for each percentage of “double ”In planting (two seeds per pit) there is a loss of 3.3% in productivity.
[04] Normalmente, 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] Normally, sowing seedlings comprise a seed conduit pipe from the selector system to the sowing furrow. The seed is transported from the conductive tube into falling in free fall from an average height of seven hundred millimeters to the sowing furrow, this system besides generating a distribution unevenness and the high coefficient of variation due to disordered seed fall, has no regulating device to control seed deposition and may have sensors in the center of the conductive tube that prevent the seed from sliding straight into the sowing furrow, disuniting its deposition.
[05] O estado da técnica apresenta diversos documentos que descrevem sistemas transportadores de sementes a vácuo, onde podemos destacar o seguinte documento:  [05] The state of the art presents several documents describing vacuum seed conveyor systems, where we can highlight the following document:
[06] O documento PCTBR2016000003, do mesmo titular, descreve um sistema dosador e transportador de sementes aplicado em semeadora que compreende uma correia taliscada dotada de angulações e espaçamentos específicos em formato triangular ou retangular que é acoplada a um dosador de sementes a vácuo dotado por uma caixa de engrenagens que possibilita uma redução do número de peças, sem a necessidade de utilizar motores elétricos e módulos eletrónicos de controle, tornando o produto compacto, simplificado e protegido das intempéries. Assim, permitindo que as sementes sejam conduzidas do sistema seletor até a linha de semeadura no solo através de uma estrutura transportadora, limitando a aceleração da gravidade na semente e irhpedindo sua deposição imediata e desuniforme na linha de semeadura. Além disso, o uso de uma correia alimentadora e direcionadora de sementes em conjunto com a correia taliscada, uniformiza o fluxo das sementes ao entrarem nos espaços da correia taliscada deixando as sementes equidistantes uma das outras e com um espaçamento exato junto ao solo. A rampa substituível permite o melhor ajuste do modo de plantio conforme a necessidade de velocidade, melhorando e mantendo mais desejável o coeficiente de variação. [06] Document PCTBR2016000003, by the same holder, describes a seeder-applied seed dispenser and conveyor system comprising a taliscus belt having triangular or rectangular shaped angles and spacings which is coupled to a vacuum seed dispenser provided with A gearbox that enables a reduction in the number of parts without the need to use electric motors and electronic control modules, making the product compact, simplified and protected from the weather. Thus, allowing seeds to be carried from the selector system to the soil sowing line through a conveyor structure, limiting the acceleration of gravity in the seed and preventing its immediate and uneven deposition on the sowing line. In addition, the use of a seed feed and directing belt in conjunction with the taliscus belt equalizes the flow of seeds by entering the spaces of the taliscus belt leaving the seeds equidistant from each other and exactly spaced close to the ground. The ramp The replaceable system allows the best adjustment of the planting mode as needed for speed, improving and maintaining the coefficient of variation more desirable.
[07] Portanto, o presente titular, realizou modificações na forma construtiva do sistema de transmissão e na forma de acionamento e sincronismo do disco seletor junto à correia taliscada de forma a resultar em uma construtividade própria, garantindo maior precisão no transporte das sementes até o sulco e evitando a geração de sementes duplas.  [07] Therefore, the present holder has made changes in the transmission system construction and in the selector disc drive and synchronization with the taliscus belt in order to result in its own constructivity, ensuring greater precision in the transport of seeds to the furrow and avoiding the generation of double seeds.
[08] Desta forma, é objeto da presente invenção, um sistema dosador e transportador de sementes a vácuo aplicado em semeadora que compreende um dosador a vácuo dotado por um sistema de transmissão que apresenta um conjunto de correntes que permitem a movimentação de todo o sistema dosador de forma a melhorar e facilitar o sincronismo de acionamento.

Além disso, esta construtividade permite que as sementes sejam conduzidas do sistema seletor até a linha de semeadura no solo, limitando a aceleração da gravidade na semente e impedindo sua deposição imediata e desuniforme na linha de semeadura.  [08] Accordingly, it is the object of the present invention a vacuum seed feeder and conveyor system comprising a vacuum feeder provided with a transmission system which has a set of chains that allow the entire system to move dispenser to improve and facilitate drive timing.
