MECANISMO PARA INTERROMPER O FLUXO DE SEMENTES EM DOSADORES DE SEMENTE A VÁCUO MECHANISM TO INTERRUPT THE FLOW OF SEEDS IN VACUUM SEED DOSERS
CAMPO DA INVENÇÃO FIELD OF THE INVENTION
[01] A presente invenção descreve um mecanismo para interromper o fluxo de sementes em dosadores de semente a vácuo. Mais especificamente compreende um mecanismo que atua nos furos dos discos seletores de sementes, empurrando e ao mesmo tempo vedando o orifício de sucção ou pressão, fazendo que as sementes caiam de volta para o reservatório sem caírem no solo, evitando sobrepasse na semeadura com redução de custos com sementes, melhor distribuição das plantas no solo e aumento de lucratividade. [01] The present invention describes a mechanism to interrupt the flow of seeds in vacuum seed dosers. More specifically, it comprises a mechanism that operates in the holes of the seed selector discs, pushing and at the same time sealing the suction or pressure orifice, causing the seeds to fall back into the reservoir without falling to the ground, avoiding overlap in sowing with a reduction of seed costs, better distribution of plants in the soil and increased profitability.
[02] O dispositivo podendo ser acionado de modo elétrico, pneumático, hidráulico ou mecânico atuando do lado oposto as sementes do disco seletor através de uma roseta dentada que entra nos orifícios do disco seletor. Quando desligado, o mecanismo se afasta do disco seletor, não interferindo no funcionamento do dosador. [02] The device can be activated electrically, pneumatically, hydraulically or mechanically, acting opposite the seeds of the selector disk through a toothed rosette that enters the holes of the selector disk. When turned off, the mechanism moves away from the selector disc, not interfering with the doser operation.
ANTECEDENTES DA INVENÇÃO BACKGROUND OF THE INVENTION
[03] Atualmente, os dosadores de semente à vácuo são constituídos por mecanismos que podem bloquear metade ou partes da semeadora através de catracas operadas de modo manual, não realizando o controle individual por linha de plantio, exigindo um operador na semeadora para realizar a tarefa. Resultando em um aumento da mão de obra e maior risco de acidentes com operador, além de ser um sistema que apresenta baixa precisão. [03] Currently, vacuum seed dosers are made up of mechanisms that can block half or parts of the seeder through manually operated ratchets, not performing individual control per planting line, requiring an operator at the seeder to perform the task . Resulting in an increase in manpower and a greater risk of accidents with the operator, in addition to being a system that has low precision.
[04] Outra forma, é a utilização de embreagens que operam através de comando eletroeletrônico instaladas nos cabos de acionamento das linhas de plantio, porém, estes sistemas apresentam um elevado custo de aquisição e manutenção.
[05] Assim, o presente inventor buscando solucionar este problema de mercado, desenvolveu um mecanismo que permite interromper o fluxo de sementes variável ou contínuo, ativando ou desativando a linha de plantio com as sementes no reservatório através de comando elétrico, Wi-Fi, bluetooth, hidráulico, mecânico ou pneumático, através de uma comunicação com a central de gerenciamento de mapas de plantio, de modo a permitir o controle linha a linha em tempo real. [04] Another way is the use of clutches that operate through an electronic command installed in the drive cables of the planting lines, however, these systems have a high cost of acquisition and maintenance. [05] Thus, the present inventor seeking to solve this market problem, developed a mechanism that allows interrupting the variable or continuous flow of seeds, activating or deactivating the planting line with the seeds in the reservoir through electric command, Wi-Fi, bluetooth, hydraulic, mechanical or pneumatic, through communication with the planting map management center, in order to allow line-by-line control in real time.
[06] Em pesquisa realizada no estado da técnica identificamos diversos documentos que reivindicam mecanismos para interromper o fluxo de sementes nos dosadores à vácuo, onde podemos destacar os seguintes documentos: [06] In research carried out in the state of the art, we identified several documents that claim mechanisms to interrupt the flow of seeds in vacuum dosers, where we can highlight the following documents:
[07] O documento BRPI1001437 (Stara. 2010) descreve um dosador de sementes em que o mecanismo de dosagem de sementes é constituído por um invólucro definindo uma câmera interna com um reservatório de sementes, o invólucro suportando rotativamente um eixo de acionamento acoplado a um disco de sementes com uma pluralidade de células de sementes, sendo dotado por um mecanismo eletroeletrônico que dispõe de uma comporta abre~fecha sobre o tubo condutor, bloqueando a saída de sementes do dosador através da remoção de sementes presas ao disco seletor por raspagem, sem interromper o vácuo nos orifícios e direcionando as sementes de volta a um reservatório. [07] Document BRPI1001437 (Stara. 2010) describes a seed doser in which the seed dosing mechanism consists of a casing defining an internal chamber with a seed reservoir, the casing rotatably supporting a drive shaft coupled to a seed disk with a plurality of seed cells, equipped with an electronic mechanism that has an open-close gate on the conductive tube, blocking the exit of seeds from the doser by removing seeds stuck to the selector disk by scraping, without breaking the vacuum in the holes and directing the seeds back into a reservoir.
[08] O documento US9338939 (Rry. 2015) descreve um disco de sementes exclusivo para uso em uma plantadeira agrícola do tipo a vácuo. As aberturas de sementes se estendem através do disco na direção da espessura da face do lado do vácuo do mesmo para a face do lado da semente oposta. Cada abertura apresenta uma abertura de porção de extremidade cilíndrica através da face do lado do vácuo do
corpo do disco, uma primeira porção cuja extremidade mais larga se comunica com a porção de extremidade cilíndrica. [08] Document US9338939 (Rry. 2015) describes a unique seed disk for use in a vacuum-type agricultural planter. The seed openings extend across the disc in the thickness direction from the vacuum side face of the disc to the opposite seed side face. Each opening has a cylindrical end portion opening through the vacuum side face of the disk body, a first portion whose wider end communicates with the cylindrical end portion.
[09] O documento US9629302 (Plantium. 2014) descreve um dispositivo de dosagem de sementes de acionamento direto para uma semeadora com uma câmara de vácuo rotativa operada por vácuo e acionada por um motor elétrico coaxial. A câmara de vácuo rotativa possui um disco dosador de sementes para captar as sementes de um reservatório e depositá-las de forma controlada em um sulco no solo. A câmara de vácuo rotativa é criada por uma placa côncava localizada dentro do alojamento e fixada de forma vedada a uma face do disco de dosagem de sementes que é fornecido a vácuo por um tubo não rotativo tendo um membro oco saliente, um flange e uma saída de extração fixada para um gerador de vácuo. [09] Document US9629302 (Plantium. 2014) describes a direct drive seed dosing device for a seeder with a vacuum operated rotating vacuum chamber and driven by a coaxial electric motor. The rotating vacuum chamber has a seed metering disc to capture seeds from a reservoir and deposit them in a controlled manner in a furrow in the soil. The rotatable vacuum chamber is created by a concave plate located within the housing and sealingly attached to one face of the seed metering disc which is vacuum supplied by a non-rotating tube having a projecting hollow member, a flange and an outlet. fixed extraction point for a vacuum generator.
[010] O documento EP3235360 (Precision. 201 1) descreve um disco de sementes giratório na direção de deslocamento, o referido disco de sementes compreendendo: uma superfície lateral da semente; um lado do vácuo; uma pluralidade de aberturas de sementes dispostas ao longo de um caminho de abertura de sementes conforme o referido disco de sementes gira na referida direção de deslocamento; e uma pluralidade de cavidades guia dispostas adjacentes às ditas aberturas de sementes no dito lado de vácuo do dito disco de sementes; e um conjunto ejetor de sementes que compreende um braço de alavanca que suporta uma roda ejetora e uma roda guia. [010] Document EP3235360 (Precision. 2011) describes a seed disk rotatable in the direction of displacement, said seed disk comprising: a lateral surface of the seed; one side of the vacuum; a plurality of seed apertures disposed along a seed aperture path as said seed disk rotates in said direction of travel; and a plurality of guide cavities disposed adjacent said seed openings on said vacuum side of said seed disk; and a seed ejector assembly comprising a lever arm supporting an ejector wheel and a guide wheel.
[011] O documento US7448334 (Deer. 2005) descreve um disco de sementes circular tipo disco plano que é fornecido com uma série de aberturas de atração de sementes dispostas circunferencialmente. As aberturas são espaçadas ao longo de um rebordo circunferencial deslocado axialmente do restante do disco para aproximar o local de
liberação da semente e as características de um disco de semente do tipo célula. O deslocamento permite que a semente caia no local correto do tubo de sementes para reduzir ou eliminar o salto indesejado de sementes e fornecer melhor distribuição de sementes ao solo e melhor espaçamento de sementes em comparação com discos planos sem deslocamento. [011] Document US7448334 (Deer. 2005) describes a flat disk-type circular seed disc that is provided with a series of circumferentially arranged seed attracting openings. The apertures are spaced along a circumferential rim offset axially from the remainder of the disc to approximate the site of seed release and the characteristics of a cell-type seed disk. Offsetting allows seed to land in the correct location in the seed tube to reduce or eliminate unwanted seed bouncing and provide better seed distribution to the soil and better seed spacing compared to non-offset flat discs.
[012] Estes documentos citados no estado da técnica descrevem mecanismos para bloquear e interromper o vácuo nos dosadores, sendo que cada documento identificado descreve uma construtividade própria. Assim, nenhum destes documentos descreve um mecanismo dotado pelas mesmas características construtivas e de acionamento disposto dentro da câmera de vácuo e acionado eletronicamente, que quando desligado não interferem no funcionamento do dosador. [012] These documents cited in the prior art describe mechanisms to block and interrupt the vacuum in the dispensers, and each identified document describes its own constructivity. Thus, none of these documents describe a mechanism with the same constructive and actuation characteristics arranged inside the vacuum chamber and electronically actuated, which, when turned off, do not interfere with the operation of the doser.
[013] Desta forma, é objeto da presente invenção, um mecanismo para interromper o fluxo de sementes em dosadores de semente a vácuo que compreende um mecanismo que atua nos furos dos discos seletores de sementes, empurrando e ao mesmo tempo vedando o orifício de sucção ou pressão, fazendo que as sementes caiam de volta para o reservatório sem caírem no solo, evitando sobrepasse na semeadura com redução de custos com sementes, melhor distribuição das plantas no solo e aumento de lucratividade. O dispositivo podendo ser acionado de modo elétrico, pneumático, hidráulico ou mecânico atuando do lado oposto as sementes do disco seletor através de uma roseta dentada que entra nos orifícios do disco seletor. Quando desligado, o mecanismo se afasta do disco seletor, não interferindo no funcionamento do dosador. Com este mecanismo, consegue-se controlar cada linha independente através do mapa de plantio com custo de fabricação e manutenção baixa propiciando redução de custo
de sementes por não haver desperdício e melhora na produtividade pelo melhor arranjo de plantas na lavoura. [013] In this way, it is the object of the present invention, a mechanism to interrupt the flow of seeds in vacuum seed dosers, comprising a mechanism that acts on the holes of the seed selector discs, pushing and at the same time sealing the suction hole or pressure, causing the seeds to fall back into the reservoir without falling to the ground, avoiding overshoot in sowing with reduced seed costs, better distribution of plants in the soil and increased profitability.

[036] Em uma das extremidades da base (1 1 ) é disposta a roseta (15) dotada por uma haste (151) que se movimenta junto a um eixo (152) fixado na porção superior da base (11), permitindo a movimentação vertical da haste (151) e roseta (15) de forma a interromper o fluxo de sementes quando acionada. [035] In the central portion of the base (1 1) is arranged the solenoid (12) equipped with a movable rod (13) and wiring (14) that allows the device to be powered. The wiring (14) is directed to the external portion of the doser through a gap (22) that receives the disposition of the connector (141), and this wire crossing point is totally insulated to avoid the loss of vacuum inside the chamber (21). [036] At one end of the base (1 1) the rosette (15) is provided with a rod (151) that moves along an axis (152) fixed to the upper portion of the base (11), allowing movement vertical stem (151) and rosette (15) in order to interrupt the flow of seeds when activated.
[037] A haste (151) da roseta (15) é fixada junto a haste móvel (13) através de uma estrutura de conexão (131) posicionada na porção inferior da haste (151), de modo que quando a haste (131) se movimenta de forma linear movimenta a haste (151) e roseta (15) verticalmente junto as furações do disco de sementes. [037] The rod (151) of the rosette (15) is attached to the mobile rod (13) through a connection structure (131) positioned in the lower portion of the rod (151), so that when the rod (131) moves linearly, moves the rod (151) and rosette (15) vertically along the holes in the seed disc.
[038] O dispositivo (10) dotado por solenoide (12), com função liga e desliga, atua na câmara de vácuo (21) posicionado a roseta (15) junto as furações do disco, interrompendo ou não o fluxo das sementes. [038] The device (10) equipped with a solenoid (12), with on and off function, acts on the vacuum chamber (21) positioning the rosette (15) next to the holes in the disc, interrupting or not the flow of seeds.
[039] O dispositivo (10) na posição liga, interrompe o fluxo das sementes direcionando-as para a rampa até o reservatório de onde repetem o ciclo. [039] The device (10) in the on position, interrupts the flow of seeds directing them to the ramp to the reservoir where they repeat the cycle.
[040] O mecanismo na posição desliga, se afasta do disco permitindo assim que as sementes presas aos orifícios sejam levadas até o ponto de soltura para um tubo condutor ou transportador de correia. [040] The mechanism in the off position, moves away from the disc thus allowing the seeds stuck to the holes to be taken to the point of release to a conductive tube or belt conveyor.
[041] Portanto, as sementes após serem sugadas pelo orifício do disco seletor, são selecionadas e transportadas até o ponto de soltura por gravidade para o condutor de tubo ou condutor de correia até o solo. O dispositivo (10) empurra as sementes para fora dos orifícios do disco seletor e, simultaneamente, elimina o vácuo ou pressão atuante nos orifícios por tamponamento através dos dentes da roseta (15), fazendo as sementes caírem na rampa de retorno fixa por gravidade, retornando
ao reservatório do dosador, evitando que as sementes caiam no condutor de tubo ou condutor de correias, e interrompendo o fluxo de sementes para o solo, quando acionado, evitando o sobre plantio onde este já foi feito.
[041] Therefore, the seeds after being sucked through the orifice of the selector disc, are selected and transported to the point of release by gravity to the tube conductor or belt conductor to the ground. The device (10) pushes the seeds out of the selector disk orifices and, simultaneously, eliminates the vacuum or pressure acting in the orifices by tamponade through the rosette teeth (15), making the seeds fall into the fixed return chute by gravity, returning to the doser reservoir, preventing the seeds from falling into the tube conductor or belt conductor, and interrupting the flow of seeds to the soil, when activated, avoiding overplanting where this has already been done.
