Description

Der Trommelförderer, geeignet zum Wenden, Beladen und Entleeren, kann durch einfache Mittel in diese Arbeitsstellungen gebracht werden. Durch Drehen der Grundplatte werden die Halter in die Stellung gebracht, daß die Klappen den Spalt offen halten. Der Trommelförderer wird in Uhrzeigersinn bewegt. Hierbei wird das Gut mittels den feststehenden Schaufeln aufgenommen und gleitet nach entsprechender Veränderung des Drehwinkels auf den Klappen herabin die Trommel. Dabei wird es mit dem in der Trommel befindlichen Gut vermischt und an der entgegengesetzten Seite ausgetragen. Dies ist der Wendevorgang. Beim Befüllen oder Beladen von Siloanlagen können sich die Klappen frei bewegen, d. h. die Grundplatte wird in die entsprechende Stellung gebracht, so daß die Halter nicht die Klappen blockieren können. Das Beladen der Trommel erfolgt mittels Schwerkraftförderer. Nach Beendigung des Füllvorganges wird derTrommelförderer an die entsprechende Entladestelle im Flachsilo verfahren und die Trommel an dieser Stelle entgegengesetzt des Uhrzeigersinns gedreht, so daß das Gut zwischen den Klappen nach außen fallen kann. Zum Entleeren von Silos können sich die Klappen wiederum frei bewegen. Die Trommel dreht sich im Uhrzeigersinn und gräbt sich durch die feststehenden Schaufeln in das Gut. Das Gut wird durch diese aufgenommen und gleitet auf den Klappen in die Trommel. Das Gut in der Trommel verschließt dabei gleichzeitig die sich auf der gegenüberliegenden Seite abwärts bewegenden Klappen. Wenn die Trommel gefüllt ist, wird sie zur Abgabestelle gefahren und entsprechend der Aktivität entleert.The drum conveyor, suitable for turning, loading and emptying, can be brought by simple means in these working positions. By turning the base plate, the holders are brought into the position that the flaps keep the gap open. The drum conveyor is moved clockwise. Here, the good is absorbed by the fixed blades and slides after a corresponding change in the angle of rotation on the flaps herabin the drum. It is mixed with the material in the drum and discharged on the opposite side. This is the turning process. When filling or loading silos, the flaps can move freely, d. H. the base plate is placed in the appropriate position so that the holders can not block the flaps. The loading of the drum takes place by means of a gravity conveyor. After completion of the filling process, the drum conveyor is moved to the appropriate unloading point in the flax silo and the drum rotated at this point counterclockwise, so that the good between the flaps can fall outward. To empty silos, the flaps can move freely again. The drum rotates clockwise and digs through the fixed blades into the estate. The material is absorbed by these and slides on the flaps in the drum. The material in the drum simultaneously closes the downwardly moving flaps on the opposite side. When the drum is filled, it is driven to the delivery point and emptied according to the activity.

DerTrommelförderer nach Fig. 1 besitzt mehrere Trommelwände 3 an denen die Schaufeln 2 starr befestigt sind. An diesen sind die Klappen 4 über Gelenke 5 elastisch z. B. durch Gurte oder Bänder angeordnet. Im geöffneten Zustand werden die Klappen 4 durch Halter 7, die auf der Grundplatte 8 kreisförmig montiert sind, fixiert. Hierbei ergibt sich zwischen den einzelnen Schaufeln 2 und Klappen 4 ein Spalt 9, der das Gut in dieTrommel 1 gelangen läßt. Um die Klappen 4 durch die Halter 7 fixieren zu können, sind die Anschläge 6 erforderlich, an denen die abgewinkelten Klappen 4 ein Widerlager finden. In der Fig. 2 wird deutlich, wie sich die Lage der Klappen 4 beim Drehen der Trommel 1 bedingt durch die Schwerkraft verändert.The drum conveyor according to Fig. 1 has a plurality of drum walls 3 on which the blades 2 are rigidly secured. At these flaps are 4 joints 5 elastically z. B. arranged by straps or bands. In the open state, the flaps 4 are fixed by holders 7, which are mounted circular on the base plate 8. Here, a gap 9 results between the individual blades 2 and flaps 4, which allows the material to enter the drum 1. In order to fix the flaps 4 by the holder 7, the stops 6 are required, where the angled flaps 4 find an abutment. In Fig. 2 it is clear how the position of the flaps 4 changes when rotating the drum 1 due to gravity.

Field of application of the invention

The invention relates to a drum conveyor for turning, loading and emptying of bulk material. Such conveyors can be used, in particular, in flat silos, mill operations and malting plants for cereals or similar agricultural bulk goods.

Characteristic of the known state of the art

Drum conveyors and paddle wheels with rigid and movable conveyor blades are known. Rigid blades for a bucket wheel excavator or a reaming implement are described in DE-OS 2934696 and DD-209083. In this bucket wheel excavator, the rear wall of the blade is moved by a chain by means of an eccentric from the outside. In the other solution, the receptacle is rotated, so that in addition to the conveying effect also allow emptying. Such or similar solutions are widely used in construction and mining. These are disclosed in DE-OS 2757328 and DE-PS 1120980. Containers, troughs, buckets or the like. On recirculatory tracks, often circular paths, out and deflected at a preselected point from the outside by stops, eccentrics or hydraulic cylinders, controlled and emptied. On certain paddlewheels, the containers are also operated by spur gears (SU-1194802). Split vanes, SU-271369, are designed such that the receiving members and back panels are hinged. In this case, the rear wall is then moved relative to the receiving organs. Another solution is described in DD-PS 124375. The blades, undivided, are guided in longitudinal grooves and brought by attacks from the outside to tilt. All described solutions definitely include the possibility of receiving and delivering bulk material. Individual solutions also allow then turning the goods, DD-209083 or the rearrangement of the same. Of course, the design requirements of such devices depend essentially on the type of bulk material. Goods with a high specific gravity such as earth, ores, rocks etc. require a much higher material input. Other devices have the disadvantage of impermissibly high dust formation, which cause a potential dust explosion hazard. Damage or compression of the transported or to be treated bulk material are recorded, resulting in a significant reduction in quality z. B. in sensitive seeds and seeds.

Object of the invention

Purpose of the invention is a reduction of the cost of producing such devices, reducing the dust turbulence and avoid damage to the bulk material to be conveyed.

Explanation of the essence of the invention

The invention has for its object to provide a turning and loading device with reduced fall height of the goods while gentle treatment of the same when turning, loading and emptying of bulk material. According to the invention the object is achieved in that a drum conveyor has a rotatable drum in both directions, has divided blades and flaps, wherein the blade part is firmly connected to the drum wall. The flap portion is elastically coupled to the fixed blade. These movable flaps, which close or release the gap between the stationary blades according to the position of the drum and the amount of crop. The fixed blades impart the required strength through their connection to the drum wall of the overall construction. The movement of the flaps, due to the position in the drum and the gravitational force acting on it, is limited by a stop. The flaps can also be fixed by means of a holder in the open position, as it is required for turning. For this purpose, the holders are mounted on the base plate, which is rotatably mounted on the outer drum walls and can be locked in two positions.
