  • Patent number: 7011217
    Abstract: An apparatus is proposed for separating coarse grain and fine grain with a screen (1) made of screen bars (3) which are situated successively adjacent to one another and slope downwardly in the conveying direction (2) of the coarse grain and with a support (4) for the screen bars (3) which are fastened to one end of the support (4) and can be excited to performed oscillations by the material to be screened. In order to ensure an especially favorable screening effect at low maintenance and production costs it is proposed that the bar-like support (4) is held in a frame (6) in a manner torsionally resilient about its longitudinal axis (5) extending transversally to the screen bars (3) and that the screen bars (3) are arranged in at least two rows disposed successively in the conveying direction (2) of the coarse grain.
