Estado da técnica : State of the art:

[ 005 ] Nos dias atuais , são conhecidos pelo atual estado da técnica diversos modelos de dosadores de sementes aplicáveis ou não a plantadeiras que , apesar de serem amplamente utili zados nos mais diversos tipos de culturas agrícolas apresentam alguns inconvenientes importantes que di ficultam sua operacionalidade como , por exemplo , elevadas dimensões e peso do conj unto, alta complexidade no manuseio e manutenção , grande quantidade de componentes e elevada demanda de energia para sua operação como os hidráulicos . [ 005 ] Nowadays , due to the current state of the art , several models of seed dispensers are known , applicable or not to planters . , for example, high dimensions and weight of the set, high complexity in handling and maintenance, large number of components and high energy demand for its operation, such as hydraulics.

[ 006 ] Por sua vez , a distribuição de sementes no solo agrícola executada por estes dosadores de sementes conhecidos é executada obrigatoriamente por implementos compreendidos por ao menos um disco rotativo de distribuição de semente , um tubo ou duto condutor de semente e/ou ar/pressão , turbinas geradoras de ar/pressão e/ou sucção , e engrenagens e redutores mecânicos de movimentação dos componentes , bem como sensores eletrônicos de contagem e/ou liberação de sementes . [ 006 ] In turn , the distribution of seeds on the agricultural soil carried out by these known seed dosers is necessarily carried out by implements comprising at least one rotating seed distribution disk, a seed and/or air/pressure conducting tube or duct, air/pressure and/or suction generating turbines, and mechanical gears and reducers for moving the components, as well as sensors electronics for counting and/or releasing seeds.

[ 007 ] O inconveniente da aplicação/utili zação destes implementos é a necessidade constante de aj ustes rotineiros e manutenções periódicas , principalmente por serem baseados em equipamentos mecânicos e eletrônicos suscetíveis à ação das intempéries e da agressividade dos constituintes dos solos agrícolas , o que pode ocasionar frequentes desaj ustes na distribuição das sementes no solo agrícola, bem como quebra de sementes e necessidade de elevada f orça/energia mecânica . [ 007 ] The drawback of applying / using these implements is the constant need for routine adjustments and periodic maintenance , mainly because they are based on mechanical and electronic equipment susceptible to the action of the weather and the aggressiveness of the constituents of agricultural soils , which can cause frequent mismatches in the distribution of seeds in the agricultural soil, as well as seed breakage and the need for high strength/mechanical energy.

[ 008 ] Nesta linha, tem se tornado imprescindível para os agricultores que manuseiam plantadeira de sementes a estruturação de um versátil , prático , seguro e preciso implemento dosador de sementes capaz de permitir uma completa otimi zação nos procedimentos de distribuição de sementes diretamente no solo de cultivo agrícola, primordialmente uma uni formi zação na distribuição das sementes no solo , com ganhos de agilidade e segurança, evitando que ocorram falhas de deposição ou mesmo deposição em multiplicidade em um mesmo ponto das sementes , bem como respeitem os princípios de cultivo de cada uma das culturas agrícolas .

[ 009 ] Neste contexto , em uma ampla análise da literatura com o intuito de estabelecer o estado da técnica vigente frente a dosadores de sementes implementados em plantadeiras agricolas , particularmente dosadores de sementes pneumáticos , obj eto da presente invenção , foram locali zados alguns documentos do estado da técnica que descrevem este tipo de implemento . Entretanto , em nenhum deles se encontra o mesmo conj unto estrutural e operacional definido pelo presente dosador pneumático e baseado em um sistema de transporte de sementes por disco rotativo entre uma câmara coletora (pulmão ) e uma câmara de sucção ( di ferencial de pressão de ar negativa - sucção de ar ) que proporciona deposição das sementes no solo de cultivo de forma regularmente espaçada . Ademais , apesar de os documentos encontrados no estado da técnica descreverem dosadores pneumáticos , nenhum deles é capaz de sugerir ou revelar um dosador pneumático com um disco coletor de sementes capaz de captar as sementes de forma mais precisa e dispensando a utili zação de palhetas singuladoras para eliminar a ocorrência de duplicidade de sementes em uma mesma cavidade do disco coletor . Ainda, nota-se que os documentos do estado da técnica revelam complexos conj untos de numerosos elementos compreendidos nos dosadores que necessitam da utili zação de parafusos ou peças de fixação adequadas para montagem final do implemente , ao passo que o dosador pneumático da presente invenção proporciona uma montagem facilitada . [ 009 ] In this context , in a broad analysis of the literature in order to establish the state of the art current against seed dosers implemented in agricultural planters, particularly pneumatic seed dosers, object of the present invention, some documents of the state of the art were located that describe this type of implement. However, none of them has the same structural and operational set defined by the present pneumatic doser and based on a seed transport system by rotating disc between a collection chamber (lung) and a suction chamber (air pressure differential negative - air suction ) which provides deposition of seeds in the cultivation soil in a regularly spaced manner .

Furthermore, it is noted that the state of the art documents reveal complex sets of numerous elements included in the dispensers that require the use of screws or suitable fastening parts for the final assembly of the implement, while the pneumatic dispenser of the present invention provides easy assembly.

[ 0010 ] Desta forma, a presente invenção se caracteri za por reunir componentes e processos em uma concepção di ferenciada, a qual atenderá as diversas exigências que a natureza da utili zação demanda, ou sej a, deposição de sementes de forma uni formi zada e precisa no solo agricola . Assim, a concepção da presente invenção garante um dosador pneumático de grande eficiência, funcionalidade , resistência, durabilidade , segurança, versatilidade , precisão , ergonomia e economia em razão das excelentes qualidades técnicas agregadas , o que proporciona vantagens e melhoras nos procedimentos de plantio de culturas agrícolas por meio de sementes a partir de plantadeiras agrícolas e cuj as características gerais di ferem das demais formas e modelos de dosadores de sementes conhecidos pelo atual estado da técnica .
