Screening machine with cassette-type screen surface sections

摘要

The invention relates to a screening machine (1) with a machine frame (10) which can be set into motion by a vibratory drive (13) and with a cassette-like arrangement arranged one behind the other in the longitudinal direction of the screening machine (1) between two parallel side walls (11, 12) of the machine frame (10) Screen surface portions (2) individually detachably connected to the vibratory machine frame (10), each screen surface portion (2) comprising a cassette frame (20), each screen surface portion (2) extending transversely across a plurality of parallel tension bars (21, 22) are arranged, wherein alternately first clamping strips (21) via rigid fasteners and second clamping strips (22) via spring elements (24) on the cassette frame (20) are mounted and wherein on the clamping bars (21, 22) extending over this flexible screen mat (23 ) is attached. The screening machine (1) according to the invention is characterized in that the cassette frame (20) in each case extends directly to the side walls (11, 12) of the machine frame (10) and is connected thereto, that the spring elements (24) below each Clamping strips (21, 22) are arranged and that each clamping strip (21, 22) seen in the transverse direction of the screening machine (1) has a length which corresponds to the distance between the two side walls (11, 12) minus a necessary movement play.
