Title
(EN) MACHINE FOR CLEANING AGRICULTURAL PRODUCTS THROUGH A PROCESS OF CENTRIFUGING IN A SPIRAL CURTAIN
(FR) MACHINE DE NETTOYAGE DE PRODUITS AGRICOLES PAR PROCÉDÉ DE CENTRIFUGATION EN RIDEAU EN SPIRALE
(PT) MÁQUINA DE LIMPEZA DE PRODUTOS AGRÍCOLAS POR PROCESSO DE CENTRIFUGAÇÃO EM CORTINA EM ESPIRAL
Abstract
(EN) The following invention abstract relates to the development of a machine for cleaning agricultural products, such as grains in general, in which the grains to be cleaned are thrown against a screening system (5) with scroll-shaped curved screens, it being the case that, when the grains are thrown by means of a grain elevation and conveyor system or bucket elevator (2), said grains move as if they were a spiral curtain, colliding with the curved surface of the screens and causing the separation of the impurities. It is possible to adjust the mesh of the screen, such that a simple adjustment allows the separation of a variety of products, without the screen having to be changed for one with a larger mesh or a smaller mesh.
(FR) Le présent abrégé d'invention concerne la mise au point d’une machine de nettoyage de produits agricoles, tels que des grains en général, les grains à nettoyer étant acheminés vers un système de tamisage (5) avec tamis incurvés en forme de volute. Lors de leur déversement, les grains passent par l'intermédiaire d’un système d’élévation de transport de grains ou élévateur de godets (2) ; lesdits grains se déplacent à la manière d’un rideau en spirale, entrant en collision avec la surface incurvée des tamis et provoquant la séparation des impuretés. Le tamis admet un réglage du maillage, de sorte qu’un simple ajustement permet la séparation de divers produits, sans nécessité de remplacer le tamis par un tamis de maillage plus large ou plus étroit.
(PT) O seguinte resumo para invenção se refere ao desenvolvimento de uma máquina de limpeza de produtos agrícolas, tais como grãos em geral, onde os grãos a serem limpos são arremessados contra um sistema de peneiramento (5) com peneiras curvas em forma de voluta, sendo que ao serem arremessados os grãos por intermédio de um sistema de elevação de transporte de grãos ou elevador de canecas (2); ditos grãos se deslocam como se fosse uma cortina em espiral, que colidem com a superfície curva das peneiras e provocam a separação das impurezas. A peneira admite regulagem de malha, de modo que um simples ajuste permite que faça a separação de diversos produtos, sem ter de mudar a peneira para uma com malha maior ou com malha menor.
