- no special measurement runs are carried out with the bucket wheel device 24, but rather the surface profile is calculated from measurement data which are determined during normal operation of the bucket wheel device.
- FIG. 2 shows a transshipment point for bulk goods, for which the paddle wheel device according to the invention is used particularly advantageously.
- the exemplary bulk goods transshipment point is used for the transshipment of bulk goods between the modes of transport, ship 3, 4, 5, train 2, and truck.
- Stocks 6, 7, 8 are provided for the intermediate storage of the bulk goods.
- the bulk goods are piled up on the stockpiles, or the bulk goods are removed from the stockpiles by bucket wheel devices 9, 10, 11 and 12 according to the invention.
- the bucket wheel devices are also connected to the conveyor belt system 13.
- FIG. 3 shows a hardware configuration for a paddle wheel device according to the invention.
- drive systems 35 are provided for the undercarriage, hoist and swivel mechanism.
- the drive system 35 is controlled by a controller 34 as a function of the measured values from angle sensors
- the setpoints for the regulation are also calculated in the controller 34.
- the controller 34 determines the surface profile of the stockpile from which bulk goods are to be mined or onto which bulk goods are to be piled, depending on measured values that are supplied by a measuring device 30.
- This measuring device 30 is advantageously designed as a semiconductor laser with a rotating mirror.
- the controller 34 is connected to a superordinate control system 36.
- the controls of a plurality of paddle wheel devices according to the invention are advantageously connected to the superordinate control system 36.
- FIG. 4 shows a detailed illustration for an exemplary hardware configuration for an inventive one
- Bucket wheel device 50 Bucket wheel device 50 has a boom 74, at the end of which a paddle wheel 72 is arranged.
