Abstract

The invention relates to an arrangement for Foerdergutaustrag from the Verladegeraet a bucket wheel excavator for the selective recovery of stored in overburden separately to be won minerals, especially in a Direktversturzkombination with fixed Übergabe. According to the invention, a longitudinally displaceable discharge conveyor (9) is arranged below the carrier (6) with looped main belt (5) which can be moved together with the carrier (6) and the carrier (6th) is movable under the structure (1) of the loading device ) is executed decoupled from the support chassis (3).

Description

The discharge conveyor can be coupled to the carrier in at least two relative positions relative to one another, which correspond to the respective operating mode "control mode" and "conveyed product discharge". In the "Fördergutaustrag" operating mode, in particular a plurality of positions can be coupled, wherein preferably at least one travel path is provided around the length of the feed chute of the discharge conveyor.

In the Regelbetriebsfahrweise the carrier is connected to the support car and also coupled to the carrier discharge conveyor moves in the same way as this. For the discharge of conveyed material from the loading device, the carrier is released from the supporting landing gear and at the same time the coupling between the carrier and the discharge conveyor is canceled. By now in the longitudinal direction independently of the support chassis movable support is at least the length of the task .churre the discharge conveyor procedure. Here, in turn, a coupling between carrier and discharge conveyor, so that in a further method of the carrier in the direction of the pivot axis of the bucket wheel excavator always a defined transfer from the main belt of the loading device is realized on the discharge conveyor. By the possibility of moving the carrier with the coupled discharge conveyor there is the possibility of a defined distribution of good on the Fahrplanum of the device, eg. B. purposes of the Bekiesens.

Ausführungsbeis'piel

The invention will be explained in more detail with reference to an embodiment. The accompanying drawings show:

Fig. 1: Arrangement in the normal operation of a Direktversturzkombination with a fixed transfer Fig. 2: Position of the arrangement during the discharge of conveyed.

The construction (1) of the loading device of a bucket wheel excavator (2), in order to avoid as much as possible during the operation Fohrspuränderungen, on its support chassis (3) a defined displacement (4). The adaptation of the required conveying length between the excavator - side task and the delivery of the material to be conveyed via the support undercarriage (3) to the receiving belt (11) of the settling of the Direktversturzkombination is in a known manner by Schleifzug the Hauptbandas (5) in which along the steel structure (1) Loading device movable support (6) realized. In the normal operating position, this carrier (6) is connected to the support chassis (3) on the abscess side via a decoupled connection (7). Under the support (6) is; arranged along the steel structure (1) of the loading device movable discharge conveyor (9), which is connected in the normal operating position via a lock (8) with the carrier (6). For Fördergutaustrag the decoupled connection (7) of the carrier (6) to the support carriage (3) and the lock (8) between the carrier (6) and discharge conveyor (9) rnlöst and the carrier (6) to bucket wheel excavator (2) along the Construction (1) to a stop (10) procedure, in which a renewed coupling in the changed relative position of carrier (6) and discharge conveyor (9) takes place. After commissioning of the discharge conveyor (9 / thus exists, according to the position of the support chassis (3) to the central axis of the bucket wheel excavator (2), the possibility to sell in the still available area of the displacement path (4)

Claims (3)

1. Arrangement for Fördergutaustrag from the loading device of a bucket wheel excavator, especially in a Direktversturzkombination with fixed transfer, in which the main band of the Verladegerätes in a longitudinally movable on the construction carrier is telescopically looped, characterized in that under the independent of the supporting chassis (3) running longitudinally movable Carrier (6) a Fördergutaustrag against the conveying direction of the main belt (5) driven discharge conveyor (9) is arranged, which is movable together with the carrier (6) and relative to this and the carrier (6) from the supporting chassis (3) is decoupled , 2. Arrangement according to claim 1, characterized in that the discharge conveyor (9) with the carrier (6) in at least two relative η positions can be coupled to each other. 3. Arrangement according to claim 1 and 2, characterized in that the discharge conveyor (9) is reversible. For this 2 pages drawings Field of application of the invention The invention relates to an arrangement for Fördergutaustrag from the loading device of a bucket wheel excavator for selective recovery of stored in overburden raw lignite, gravel u.a., Especially in a Direktversturzkombination with fixed transfer between excavator and spreader. Characteristic of the known state of the art In many cases, in the case of direct camber combinations, it is necessary to extract pebble or raw lignite from the overburden. In a free transfer between the excavator and spreader Fördergutaustrap can be done by means of Verladeband the Verladegerätes, the possibilities of Austrages are restricted by the Schwenkwinkelbegrenzung the Verladebandes. In addition, it is disadvantageous that the proportion of secondary work times increases due to reversal and positioning times. For fixed transfer points between excavator and spreader Dii oktversturzkombination in which the Verladeband for Fördergutaustrag is no longer available, it was proposed to nu'zen the recording tape of the spreader for Fördergutaustrag in which this is designed to be reversible. The disadvantage here is the necessary use of a belt truck, otherwise ^ he available tilting space is too low. In realizing this proposal there are also Platzprblerre regarding the transfer between weaners and belt cars. Also increases by the reversibility of the long recording tape of the spreader Gurtschieflaufgefahr. According to DD-PS 218140 a device for the selective extraction of lignite coal from the Abtragsbereich a overburden conveyor bridge is known in which below the transfer point between the main and Haldenband a reversible sand is arranged, the two further conveyor belts are arranged downstream for the purpose of Fördergutaustrages. The use of such a system is not possible due to the low height and the limited space in the transfer area of the loading device to the receiving conveyor of the settler. To this comes the variable span of the Verladegerätes and the associated Verlanget or shortening of the band, which can not be controlled by a rigid Gurtbandfördersvstem for the deflection of the crop flow. Object of the invention The invention has the aim of being able to economically dispose of minerals to be extracted from the loading device of a bucket wheel excavator of a direct twist combination in addition to the spoil while maintaining the device position of the Regelbetriebsfahrweise. Explanation of the essence of the invention The invention has for its object to provide a sufficient dumping space-saving arrangement for Fördergutaustrag from the Verladegerät a bucket wheel excavator that secures the Fördergutaustrag at free or fixed transfer between bucket wheel excavator and downstream system and variable span of the Verladegerätes and variable coverage of the conveyor. According to the invention the object is achieved in that the loading device of the bucket wheel excavator an additional discharge conveyor is arranged below the existing carrier with looped main band, which is movable together with the carrier and relative to this and the carrier from the support chassis of the Verladegerätes can be decoupled. The carrier is designed to be movable independently of the supporting undercarriage along the steel structure. The discharge conveyor is driven in Fördergutaustrag contrary to the conveying direction of the main belt. With reversible design, it is possible to use the discharge conveyor in the normal operation of the excavator as a dirt tape? U.
