Abstract
A sieving device with a vibratory supporting frame and a vibration frame which is held against said supporting frame so as to be able to vibrate freely. A simple, compact design which provides good sieving and conveying performance is achieved in that the vibration frame is spring-elastically coupled to the supporting frame by torsion-bar-like spring elements.
Claims25
A sieving device comprising:
- a vibratory supporting frame,
- a vibration drive acting upon said supporting frame, and
- a vibration frame held against said supporting frame via spring elements,
- wherein the vibration frame is spring-elastically coupled to said supporting frame,
- wherein said vibration frame can vibrate essentially freely in one direction of vibration,
- wherein said supporting frame and said vibration frame comprise transverse supports which are alternately arranged one behind the other in a direction of vibration, and which are adapted to carry sieve bottom elements which can be tensioned and untensioned in the direction of vibration, and
- wherein said spring elements are torsion-bar-like springs.
