  • a disadvantage of this embodiment is that the drive units to drive the shafts on the side of the bucket are arranged.
  • the necessary for the drive units Lateral construction volume is disadvantageous in operation Dead space.
  • Dead space For example, when driving in with the bucket of the screen breaker in a silo or along the wall material between the side wall of the bucket and the building wall cannot be detected.
  • the housing of the drive units is heavily worn and exposed to contamination. This has among other things result in the fastening screws of the cover plates cannot be removed due to damage or contamination become. It is then necessary to use the screws or the Separate cover plates. Maintenance and inspection the drive units is therefore considerably more difficult.
  • the invention is based on this prior art based on the task of a device for sieving and / or crushing screen materials to create their Sieber success is improved with increased throughput and those disadvantageous of those described above Properties is exempt.

  • the main idea of the invention is the arrangement of the screen shafts transverse to the axis of rotation of the bucket. Are preferred the sieve shafts arranged perpendicular to the axis of rotation.
  • the screen shafts are shorter than in the known design executed, whereby significantly higher torques can be transmitted are. Due to the transverse arrangement, more screening shafts can be used be arranged in the bucket, which consequently requires greater movement of the sieve material. The stronger movement improves sieving success and leads to an increase of throughput. Because with this type of rotary sieve the sieve material through the rotation of the sieve shafts or the sieve elements is moved on the sieve bottom results also by the transverse position of the screen shafts Larger screen section compared to the known device.
  • the device is suitable for sieving and / or crushing different sieve materials, e.g. Excavation, Filter cake, coal, compost but also for separation excavation of larger components such as rubble or wood.

  • the sieve disks can basically be a round, oval or have a polygonal outer contour. Between two A spacer body is arranged in each case.
  • the sieve elements can consist of two detachable disc segments be composed (claim 5). That has the advantage, that individual sieve elements can be replaced, without having to dismantle the entire screen shaft got to. It is possible that the sieve and the spacer in individual disc segments are divided. A slice segment of the spacer but can also with the corresponding disc segment Screen disc connected in one piece. In the latter case has a sieve element only two disc segments, whereby the number of components is reduced.
  • the crushing elements are the sieve elements interchangeable. This has in particular maintenance and maintenance advantages. Is preferred between two sieve disks each with a crushing body attached. Within the scope of the invention, several crushing bodies can also be used be assigned to a sieve element.
  • the crushing bodies can be spiral or different Patterns on the circumference of the sieve shaft in the longitudinal direction distributed attached.
  • Cutting bars are also possible as crushing bodies, so that material could even be milled with the device, for example leaves, bark and the like.
  • the screen shafts are individual or in groups summarized and can with different or changeable directions of rotation are driven.
  • the Bucket moves back and forth, i.e. changing the direction of sieving, the throwing out of stones suppressed by the sieve waves.
  • the Bucket s upright and preferably at right angles to Bottom plate arranged side walls through which, if necessary Stone chips are caught in the bucket.
  • a shielding plate or a deflector to provide.
  • sieve shafts are alternating with crushing bodies or without crushing bodies arranged.
  • the screen shafts without crushing bodies act opposite the waves with crushing bodies as a kind of shear bar.
  • the outer is provided To design sieve shafts without crushing bodies. Furthermore it is convenient to have a combing between on the side walls engaging the spacers of the outer sieve shafts Arrange scraper plate so that the screenings do not get between the side wall and the sieve shaft can.
