Claims (13)
- Claims:1. A bucket wheel for a bucket wheel excavator for removing materials from a material composite, particularly of high hardness, the bucket wheel having a base body which extends about a bucket wheel rotational axis and on which, distributed about the circumference, a plurality of buckets with bucket cutters are accommodated, and wherein a plurality of cutting teeth, which can be moved on respective orbits about bucket wheel rotation axis by the rotation of the base body are arranged on each bucket cutter, and the cutting teeth which are accommodated on bucket cutters which are adjacent to one another are arranged at least partially offset with respect to one another, with the result that said bucket teeth can be moved on orbits which are offset in the direction of the bucket wheel rotational axis, wherein a bucket has at least two bucket cutters, wherein one of the bucket cutters forms a main bucket cutter on which a bucket shell is arranged.
- 2. The bucket wheel as claimed in claim 1, wherein at least two, three, four or more bucket cutters with cutting teeth which are arranged offset with respect to one another are accommodated distributed in a periodic sequence in the circumferential direction (R) of the base body, with the result that each cutting tooth on bucket cutters which are adjacent to one another is assigned a separate digging cross section.
- 3. The bucket wheel as claimed in claim 1 or claim 2, wherein the bucket cutters are embodied in an arcuate shape and have a bucket cutter width (b) which runs in the direction of the bucket wheel rotational axis and a bucket cutter depth (t) which runs in the radial direction, wherein the ratio of the bucket cutter depth (t) with respect to the bucket cutter width (b) has a value of 0.1 to 0.7, preferably from 0.15 to 0.5 and particularly preferably from 0.2 to 0.4.
- 4. The bucket wheel as claimed in any one of claims 1 to 3, wherein the bucket cutters have side sections which run to a point towards the bucket center, wherein the direction of extent of the side sections encloses an attitude angle (a) of less than 60°, preferably of less than 55° and particularly preferably of less than 50° with the bucket wheel rotational axis.2014230973 25 May 2018
- 5. The bucket wheel as claimed in any one of the preceding claims, wherein the bucket wheel has a cutting circle diameter, wherein the ratio of the cutting circle diameter with respect to the bucket cutter width (b)- has a value of less than 4, preferably of less than 3.5 and particularly preferably of less than 3 in the case of bucket wheels with a cutting circle diameter of less than 7 m,- a value of less than 5, preferably of less than 4.5 and particularly preferably of less than 4 in the case of bucket wheels with a cutting circle diameter of 7 m to 13 m,- a value of less than 6, preferably of less than 5.5 and particularly preferably of less than 5 in the case of bucket wheels with a cutting circle diameter of 13 m to 18 m, and- a value of less than 7, preferably of less than 6.5 and particularly preferably of less than 6 in the case of bucket wheels with a cutting circle diameter of more than 18 m.
- 6. The bucket wheel as claimed in any one of the preceding claims, wherein the buckets have bucket frames on which the bucket cutters are accommodated, and wherein the buckets are detachably arranged on the base body.
- 7. The bucket wheel as claimed in claim 6, wherein the bucket frames have a H-shaped structure with two longitudinal beams running parallel and a transverse beam running between the longitudinal beams, the bucket cutters are accommodated on the longitudinal beams and extend between them in an arcuate shape.
- 8. The bucket wheel as claimed in any one of the preceding claims, wherein a bucket has at least two, preferably three and particularly preferably four or more bucket cutters, wherein one of the bucket cutters forms a main bucket cutter on which a bucket shell is arranged.
- 9. The bucket wheel as claimed in any one of the preceding claims, wherein the bucket cutters are at a distance from one another in the circumferential direction (R) which corresponds to twice the main dimensions of the digging cross sections with the result that the distance between the bucket cutters produces a screening function.2014230973 25 May 2018
- 10. A bucket for a bucket wheel of a bucket wheel excavator for removing materials from a material composite, particularly of high hardness, which bucket can be arranged on a base body which extends about a bucket wheel rotational axis, wherein bucket cutters are accommodated on the bucket, and wherein a plurality of cutting teeth, which can be moved on respective orbits about the bucket wheel rotational axis by rotation of the base body, are arranged on each bucket cutter, and the cutting teeth, which are accommodated on bucket cutters which are adjacent to one another are arranged at least partially offset with respect to one another, with the result that said bucket teeth can be moved on orbits which are offset in the direction of the bucket wheel rotational axis, wherein a bucket has at least two bucket cutters, wherein one of the bucket cutters forms a main bucket cutter on which a bucket shell is arranged.
- 11. The bucket for a bucket wheel as claimed in claim 10, embodied as claimed in any one of claims 2 to 9.
- 12. A method for removing materials from a material composite, in particular of high hardness, having at least one bucket for a bucket wheel of a bucket wheel excavator on which cutting teeth are accommodated, in particular by means of bucket cutters, wherein the cutting teeth can be moved on at least two orbits by moving the bucket, wherein- cutting teeth of a first arrangement are moved on respective first orbits through the material composite, and wherein by the movement of the bucket, subsequently- cutting teeth of a second arrangement are moved on respective second orbits through the material composite, wherein the second orbits are offset with respect to the first orbits in the direction of the bucket wheel rotational axis, whereas a bucket has at least two bucket cutters, wherein one of the bucket cutters forms a main bucket cutter to which cutting teeth of the first arrangement is arranged and one of the bucket cutters on which a bucket shell is arranged and to which cutting teeth of the second arrangement are arranged.
- 13. The method for removing materials as claimed in claim 12 with a bucket wheel as claimed in any one of claims 1 to 9.WO 2014/1399271/4PCT/EP2014/054547WO 2014/139927PCT/EP2014/0545472/4 iWO 2014/139927PCT/EP2014/0545473/4Fig. 8WO 2014/139927PCT/EP2014/0545474/4Prior Art
