Insgesamt sind in dem Ausführungsbeispiel der Fig. 1 bis 3 fünf Antriebsträger 28 angeordnet, die jeweils zwischen zwei benachbarten Strukturelementen 30 der Profilstruktur 20 angeordnet sind.Furthermore, the radiator 10 has an in Fig. 3 and 5 shown conveyor unit 14. The conveying unit 14 comprises a drive carrier 28 extending in the conveying direction, a conveying element carrier 32 and a plurality of conveying elements 16. The conveying elements 16 are arranged above the ventilating floor 12 and each comprise a region extending in the conveying direction, on which, for example, three extend transversely to the conveying direction Driver 38 are mounted. The conveying elements 16 are arranged, for example, in five rows, each with three conveyor elements 16 arranged next to one another in the conveying direction. The conveying elements 16 are parallel to each other and spaced transversely to the conveying direction to each other arranged. The conveyor element carrier 32 is substantially plate-shaped and extends in the vertical direction. Each conveyor element 16 is attached to two conveyor element carriers 32, wherein two conveyor elements 16 are attached to each conveyor element carrier 32. Below the ventilation floor 12, a plurality of drive carriers 28 are arranged, which extend in the conveying direction and are connected by way of example with four conveyor element carriers 32 each. Overall, in the embodiment of Fig. 1 to 3 arranged five drive carrier 28, which are each arranged between two adjacent structural elements 30 of the profile structure 20.

Die Antriebsträger 28 sind jeweils mittels Lagerungseinheiten 22 an der Profilstruktur 20 zwischen zwei benachbarten Strukturelementen 30 angebracht. Jeder Antriebsträger 28 ist beispielhaft über zwei Lagerungseinheiten 22, insbesondere Gleitlager, an der Profilstruktur 20 angebracht, sodass eine relative Bewegung des Antriebsträgers 28 zu den Strukturelementen 30 der Profilstruktur 20 ermöglicht wird. Die Lagerungseinheit 22 weist zwei im Wesentlichen u-förmige Führungselemente 24 auf, die mit jeweils einem Gleitelement 26 zusammenwirken, sodass das Gleitelement 26 entlang des sich in Förderrichtung erstreckenden Führungselements 24 gleitet. An jedem der Antriebsträger 28 ist eine Antriebseinrichtung 18 angeordnet. Die Antriebseinrichtung 18 umfasst einen Hydraulikzylinder, der mit seinem einen Ende an der Profilstruktur 20, insbesondere an benachbarten Strukturelementen 30 der Profilstruktur 20 und mit seinem anderen Ende an dem Antriebsträger 28 angebracht ist.The drive carriers 28 are each mounted by means of storage units 22 on the profile structure 20 between two adjacent structural elements 30. Each drive carrier 28 is attached by way of example via two bearing units 22, in particular sliding bearings, to the profile structure 20, so that a relative movement of the drive carrier 28 to the structural elements 30 of the profile structure 20 is made possible. The bearing unit 22 has two substantially U-shaped guide elements 24, which cooperate with a respective sliding element 26, so that the sliding element 26 slides along the guide element 24 extending in the conveying direction. At each of the drive carrier 28, a drive device 18 is arranged. The drive device 18 comprises a hydraulic cylinder which is attached with its one end to the profile structure 20, in particular to adjacent structural elements 30 of the profile structure 20 and with its other end to the drive carrier 28.

Fig. 5 zeigt eine detaillierte Darstellung der Fördereinheit 14 ohne die Antriebseirichtung 18 und die Förderelemente 16. Der Antriebsträger 28 weist vier in Förderrichtung nebeneinander angeordnete Förderelementträger 32 auf, die im Wesentlichen T-förmig ausgebildet und gleichmäßig zueinander beabstandet angeordnet sind. Der Antriebsträger 28 und die Förderelementträger 32 sind beispielsweise aus einem Stück, miteinander verschraubt oder verschweißt ausgebildet. Ferner umfasst der Antriebsträger 28 vier Gleitelemente 26 der Lagerungseinheit 22, wobei jeweils zwei Gleitelemente 26 an einer Seite des Antriebsträgers 28 zueinander in Förderrichtung beabstandet angebracht sind. Der Antriebsträger 28 umfasst des Weiteren auf der unteren dem Belüftungsboden 12 abgewandten Seite einen Anschluss 36 zum Anbringen der Antriebseinrichtung 18 an dem Antriebsträger 28. Fig. 5 shows a detailed illustration of the conveyor unit 14 without the Antriebseirichtung 18 and the conveyor elements 16. The drive carrier 28 has four in the conveying direction juxtaposed conveyor element carrier 32 which are formed substantially T-shaped and uniformly spaced from each other. The drive carrier 28 and the conveyor element carrier 32 are formed, for example, in one piece, bolted together or welded. Furthermore, the drive carrier 28 comprises four sliding elements 26 of the bearing unit 22, wherein in each case two sliding elements 26 are mounted on one side of the drive carrier 28 spaced apart in the conveying direction. The drive carrier 28 further comprises on the lower side facing away from the ventilation bottom 12 a connection 36 for attaching the drive means 18 to the drive carrier 28th

Im Betrieb des Kühlers 10 wird jede der Fördereinheiten 14 mittels einer jeweiligen Antriebseinrichtung 18 in Förderrichtung und entgegen der Förderrichtung bewegt. Insbesondere werden die Fördereinheiten 14 gemeinsam in Förderrichtung bewegt und getrennt voneinander entgegen der Förderrichtung bewegt. Wird beispielsweise grobes Schüttgut zum Kühlen auf den Belüftungsboden 12 aufgegeben, bildet dies eine relativ kompakte Einheit, die bei einem gemeinsamen Vorhub der Fördereinheiten 14 in Förderrichtung transportiert werden kann. Die getrennte Bewegung der Fördereinheiten 14 entgegen der Förderrichtung bewirkt, dass aufgrund von Reibung weniger Schüttgut über die Mitnehmer der Förderelemente 16 mitgenommen wird als bei einer gemeinsamen Bewegung der Fördereinheiten 14. Dies resultiert insgesamt in einer Bewegung des Schüttguts entlang des Belüftungsbodens 12 in Förderrichtung.During operation of the cooler 10, each of the conveyor units 14 is moved by means of a respective drive device 18 in the conveying direction and counter to the conveying direction. In particular, the conveyor units 14 are moved together in the conveying direction and moved separately from each other against the conveying direction. If, for example, coarse bulk material is fed onto the ventilation floor 12 for cooling, this forms a relatively compact unit which can be transported in the conveying direction during a common advance stroke of the conveyor units 14. The separate movement of the conveyor units 14 against the conveying direction causes due to friction less bulk material is taken over the driver of the conveyor elements 16 as in a common movement of the conveyor units 14. This results in a total movement of the bulk material along the ventilation floor 12 in the conveying direction.

Die Anordnung der Antriebsträger 28 auf der gleichen Höhe der Profilstruktur, insbesondere zwischen zwei benachbarten Strukturelementen 30 der Profilstruktur 20 ermöglicht eine besonders kompakte Bauweise des Kühlers 10.The arrangement of the drive carrier 28 at the same height of the profile structure, in particular between two adjacent structural elements 30 of the profile structure 20 allows a particularly compact design of the radiator 10th
