Abstract
"LIMPADORA DE GRãOS". O presente relatório de patente de invenção, refere-se a uma limpadora de grãos utilizada em cooperativas, fazendas e pequenas propriedades, e tem por objetivo a separação dos resíduos de lavoura (palha, sabugo, pedras, poeira, etc.) e a seleção dos grãos como: milho, soja, trigo, feijão, café, pipoca e etc. Do estado da técnica se conhecem limpadoras de grãos com duas peneiras concêntricas, sendo a peneira interna tem formato cónico, o que implica em um problema causado pela dificuldade na confecção, e substituição da tela da peneira. Com o objetivo de superar os problemas existentes, desenvolveu-se a limpadora de grãos com peneiras concêntricas, sendo a interna também com formato cilíndrico, cujas características construtivas introduzidas no equipamento proporcionam velocidade adequada de passagem e a eficiência do processo com simplicidade na troca da tela. Na limpadora desenvolvida os dois rotores concêntricos sendo o interno (1) no formato cilíndrico, contém uma hélice de perfil retangular (9), sendo posicionada a uma distancia da entrada do material com o uso das pás inclinadas (10) e a chapa defletora (11) de formato cilíndrico instalada concentricamente ao rotor externo. Os desenvolvimentos implementados determinam uma limpadora com eficiência superior na separação dos grãos, simplicidade na substituição da peneira interna, maior durabilidade e eficiência das transmissões oferecendo vantagens e soluções aos problemas encontrados nos equipamentos conhecidos da técnica."GRAIN CLEANER". This patent report relates to a grain cleaner used in cooperatives, farms and small farms, and aims at separating crop residues (straw, cob, stones, dust, etc.) and selecting grains such as corn, soybeans, wheat, beans, coffee, popcorn and etc. From the state of the art are known grain cleaners with two concentric sieves, and the internal sieve has conical shape, which implies a problem caused by the difficulty in making, and replacement of the sieve screen. With the objective of overcoming the existing problems, the grain cleaner with concentric screens was developed, being the internal one also with cylindrical shape, whose constructive characteristics introduced in the equipment provide adequate speed of passage and the efficiency of the process with simple change of the screen. . In the developed cleaner the two concentric rotors, the inner one (1) in cylindrical shape, contain a rectangular profile propeller (9), being positioned at a distance from the material inlet using the inclined blades (10) and the baffle plate ( 11) of cylindrical shape concentrically installed to the external rotor. The implemented developments determine a cleaner with superior grain separation efficiency, simplicity of internal sieve replacement, greater durability and transmission efficiency offering advantages and solutions to problems encountered in equipment known in the art.
