Abstract

Una criba mejorada apropiada para utilizarse en máquinas cosechadoras de granos y similares, que comprende un bastidor; una serie de tiras de material laminar montadas sobre el bastidor en relación superpuesta, de modo que sean giratorias alrededor de ejes paralelos respectivos; y un mecanismo regulador o de mando unido a las tiras, para efectuar movimientos de pivotación simultáneos de las tiras sobre dichos ejes para cambiar el grado de apertura de la criba; caracterizada dicha criba porque cada una de las mencionadas tiras tiene una serie de rampas de caras planas formadas en la misma, que se extienden en la dirección del eje geométrico de giro de la tira y que presentan resistencia al flujo del grano en dicha dirección.
