a clearing device having a paddle wheel. IcJOOOH /

There are clearing devices of various designs known, in which a harrow pourable material from a heap dismantles, paddle wheels pick up the dismantled bulk material and transferred to a cross conveyor belt. These known devices are used to dismantle several piles of bulk material provided with transfer platforms, so do not belong to the category described at the beginning *

The invention is based on the object of a conveyor system of the type mentioned above with regard to the To make training and development more economical without impairing their performance.

According to the invention, a conveyor system is provided for this, in which the bridges on both sides in the face direction the pile are movable and each equipped with at least one lane in which the clearing device movable or, when the bridges are in the starting position, are arranged so that they can be traversed into the respective adjacent bridge is.

It is useful that the clearing device has a C-support provided with running wheels with a rotatably mounted on this Upper part, in which a cantilever arm for the paddle wheel is pivotably attached, as well as one below the C-support arranged cross conveyor belt with running wheels.

It can also be recommended that the conveyor system the bridges are each equipped with outer lanes and inner lanes on which the clearing device movable with its C-support and its cross conveyor belt is stored, the latter being arranged and deposited on a bridge after the clearing device has been moved for working movement along the outer lane only the C-support provided with the parts attached to it

In the clearing device, the extension arm with the paddle wheel can expediently be pivoted vertically and radially and thus designed for bilateral removal of bulk material on the front sides of piles lying one behind the other.

Further advantages and features of the invention follow from the following description of one in the drawing shown example, with Fig. 1 in a diagrammatic representation a plan view of the system, Fig. 2 shows a front view of the installation and Fig. 3 shows a side view of the clearing device.

Between the front sides of the bulk material piles l6, which are lined up next to and behind one another in any number Bridges 1A are arranged, which can be moved on rails 26 on both sides in the front side direction of the pile. the Bridges 14 are each provided with one on their upper surface outer roadway 25 and an inner roadway 13 configured. In the starting position of bridges 14 there is such a thing continuous outer and inner lane formed on which a clearing device 28 is arranged to be movable over all bridges or from one bridge to the next Crossed the bridge. The clearing device 28 comprises a loosening device, for example a harrow 15 which Can be moved with the device in a manner known per se, adjustable in the angle of repose and on a paddle wheel 1 is articulated, which is attached to a cantilever arm 2. The cantilever arm 2 is in one by a support structure formed upper part 3 arranged vertically pivotable. The top 3 is on the top surface one equipped with a chassis C-support 4 rotatably mounted, the rotary joint 5 is in the upper Area of the device, formed above the conveyor belts. The C-support 4 is designed so that a radial movement of the extension arm 2 with the upper part 3 by 180 ° and thus a bilateral removal of bulk material piles l6 lying one behind the other at the end faces is possible.

For vertical pivoting of the cantilever arm 2 with the Bucket wheel 1 is a block and tackle 6, which is operated by a winch 7, is provided. In the cantilever arm 2 is a Conveyor belt 8 arranged, -which with its end opposite the paddle wheel in the area of an over a material guide 10 located chute 9 extends into it. Under the material guide 10 is a with a Chassis equipped in the direction of the chassis of the C-pillar 4 or the lanes of the bridge l4 extending cross conveyor belt 11 is provided. The cross conveyor belt 11 is designed with running wheels 12 and drives with these in the inner lane 13 of the bridges l4 together with the C-support 4, which with its running wheels 24 drives in the outer lane 25 of the bridges l4, so that the entire clearing device 28 with the cross conveyor belt 11 in the position of the bridges l4 in the starting position can drive over each adjacent bridge and is movable in the total area of all bulk material dumps l6. the Material guide 10 extends essentially over the entire length of the cross conveyor belt 11 and is with this mobile. After driving over the clearing device 28 from one bridge to the other, the cross conveyor belt becomes 11 attached to this bridge. The actual clearing device 28, i.e. the C-support 4 with the upper part 3 » the boom 2, paddle wheel 1 and harrow 15 1> © * · β ^ then during the work process in the outer lane 25 in the area of the bridge back and forth, the transverse conveyor belt 11 is reversible in the sense of the working movement of the clearing device.

Between the bridges l4 main conveyor belts 17 are arranged along the bulk material dumps l6, which are connected to a roadway 20 for a roller table 21 with feed chute 22 is equipped, each main conveyor belt being assigned a roller table. The roller table 21 is with the each bridge l4 located in the working position is coupled and can be moved with this. The roller table 21 forms a unit with a cable drum 23 for Power supply for both sides. The bridges

ΐΛ have vertically pivotable end sections 27 which enable the bridge in the working position to be driven through

Outer feed belts l8 arranged along the heaps also serve to fill up the bulk material heaps Stacking devices 19.

During the work process, the bulk material is by means of the Harrow 15 released, taken up by the paddle wheel 2 and via the conveyor belt 8, the chute 9 and the material guide 10 passed onto the cross conveyor belt 11. From this the material is on the feed chute 22 and the roller table 21 transferred to the main conveyor belt 17. The bridge in working position moves with the clearing device in this or that end face direction of the bulk material dumps, with the boom arm to both sides Removal of bulk goods is formed on the end faces, i.e. can be pivoted radially by 180 °.

The advantage of the inventive conveyor system with a clearing device consists in the fact that for the dismantling of any number of bulk material heaps only one dismantling device with a cross conveyor belt is required, whereby otherwise common transfer platforms are omitted, the time-consuming earthworks, Fundamentals, and, require heavy constructions. Due to the fact that the cantilever arm can be given away radially The paddle wheel also eliminates the need to turn the buckets or shovels when the conveying direction is changed. The rotary connection between the upper part, which is usually provided between the cross conveyor belt 11 and the feed belt 8 and C-pillar, in which there is a very considerable undesirable high fall height of the material, is here by a Swivel connection 5 above the C-support, i.e. in the upper area of the device, which enables a low fall height. Furthermore, the construction of the conveyor system enables only one cable drum to be required for both clearing sides is. ,;
