Abstract
The invention relates to a device for sorting particulate materials of different grain size that can be part of a construction machine or digger's scoop. The device for sorting has a plurality of helical rollers, each exhibiting at least one helix, wherein each helical roller rotates about a rotary axis of its own, at least two adjacent helical rollers exhibit the same direction of rotation, and the rotary axes of at least three helical rollers are not arranged in a common plane. At least some of the helical rollers are held and rotatably mounted exclusively at one end.
Claims16
A device for sorting, comprising:
- a plurality of helical rollers, each roller exhibiting at least one helix, wherein each helical roller is rotatable about a rotary axis of its own, at least two adjacent helical rollers are rotatable in a same direction of rotation, and the rotary axes of at least three helical rollers are not arranged in a common plane, and the plurality of helical rollers together form a sorting surface that is curved at least in a partial region thereof so that a force generated by weight of a sorting material to be sorted with the device for sorting is exerted onto the sorting material in said curved partial region;
- wherein all of the helical rollers are held and rotatably mounted exclusively at one end;
- and
- wherein the sorting surface formed by the plurality of helical rollers is pivotable about a pivot axis that is arranged in a plane which is perpendicular to the rotary axes.
A digger's scoop, comprising:
- a device for sorting that has a plurality of helical rollers, each roller exhibiting at least one helix, wherein each helical roller is rotatable about a rotary axis of its own, at least two adjacent helical rollers are rotatable in a same direction of rotation, and the rotary axes of at least three helical rollers are not arranged in a common plane, and wherein all of the helical rollers are held and rotatably mounted exclusively at one end, with the opposite ends of the helical rollers not held or mounted;
- said device defining a filling opening for receiving material to be sorted;
- and
- said device further defining a lateral opening which is different from the filling opening and is located in a side wall of the scoop adjacent to and in front of said opposite ends of the helical rollers not held or mounted for expelling material sorted by the device that has an oversize grain size from the opposite ends of the helical rollers, wherein material sorted by the device of a finer grain size is expelled between the rollers.
