Abstract

A hopper unloading device which consists of an unloading frame (2) which rotates above the bottom (3) of the hopper (1) and allows granular material, e.g. chippings, to drop from the hopper into a shaft (4) located below it, from which shaft the material is conveyed further by means of an unloading conveyor (5) provided in conjunction with said shaft. For the circle of the unloading frame, a separate annular space (8) encircling the casing of the hopper is present, in which a scraper (6) attached to the circle of the unloading frame (2) conveys the material particles, which have flowed there, into the shaft (4). <IMAGE>

Description

Gegenstand dieser Erfindung bildet eine Siloentladevorrichtung, die aus einem, über dem Boden des Silos rotierenden Entladerahmen besteht, der körniges Material, z. B. Späne, aus dem Silo in einen darunter befindlichen Schacht fallen läßt, aus dem das Material mit einem in Verbindung mit ihm vorgesehenen Entladungsförderer weiter befördert wird.This invention relates to a silo unloading device, which consists of an unloading frame rotating above the bottom of the silo consists of the granular material, e.g. B. chips from the silo into one drop below the shaft from which the material with a discharge conveyor provided in connection with it is transported further.

Ein Nachteil bekannter Siloentladevorrichtungen dieser Art, bei denen das Rotieren des Entladerahmens so verwirklicht wird, daß er am Kreis z. B. durch einen Druckzylinder schrittweise bewegt wird, ist, daß Späne aus dem Silo sehr oft dazwischen kommen.A disadvantage of known silo unloading devices of this type which the rotation of the unloading frame is realized so that he at the z. B. gradually moved by a pressure cylinder is that chips from the silo very often intervene.

Zweck dieser Erfindung ist, den obenerwähnten Nachteil zu beseitigen. Eine Siloentladevorrichtung nach der Erfindung ist dadurch gekennzeichnet, daß für den Kreis des Entladerahmens ein separater, den Mantel des Silos umkreisender ringförmiger Raum da ist, in dem ein am Kreis des Entladerahmens befestigter Schaber die dort geflossenen Materialteilchen in den Schacht befördert. Durch diese Erfindung bleibt der Bewegungsmechanismus des Entladerahmens also stets rein, weshalb er keiner regelmäßiger Reinigungen bedarf.The purpose of this invention is to overcome the above mentioned disadvantage remove. A silo unloading device according to the invention is characterized in that for the circle of the unloading frame separate circular space encircling the jacket of the silo is in which a scraper attached to the circle of the unloading frame the material particles that have flowed there are conveyed into the shaft. Through this invention, the movement mechanism of the Unloading frame so always clean, which is why he is not a regular Cleaning needs.

Eine günstige Anwendungsform der Erfindung ist dadurch gekennzeichnet, daß der ringförmige Raum einen vom Boden des Silos separaten, weiter unten liegenden Boden hat, über welchem der Schaber geht. Dies ist eine günstige Konstruktion, in welche Materialteilchen, wie Späne, frei fließen können.This is a favorable application form of the invention characterized in that the annular space one from the bottom of the  Silos has separate, lower floor, above which the scraper goes. This is a cheap construction in which Material particles such as chips can flow freely.

Eine andere Anwendungsform der Erfindung ist dadurch gekennzeichnet, daß der ringförmige Raum ein den Mantel des Silos tragendes Element ist.Another form of application of the invention is thereby characterized in that the annular space a the coat of the Silos is the supporting element.

Noch eine günstige Anwendungsform der Erfindung ist dadurch gekennzeichnet, daß der untere Rand des Mantels des Silos mit einem Stützring verstärkt ist. Dadurch wird die Konstruktion des Unterteils des Silos sehr fest.Another advantageous form of application of the invention is thereby characterized in that the lower edge of the jacket of the silo with a support ring is reinforced. This will help the construction of the Lower part of the silo very firm.

Die Erfindung wird im folgenden anhand eines Beispiels erläutert, wobei auf die Zeichnung hingewiesen wird, die den Unterteil eines Silos teilweise in Schnitt darstellt.The invention is explained below using an example, being drawn to the drawing which The lower part of a silo is partly in section.

Die Siloentladevorrichtung besteht aus einem, über dem Boden 3 des Silos 1 rotierenden Entladerahmen 2, der Späne aus dem Silo in einen darunter befindlichen Schacht 4 fallen läßt, aus dem die Späne mit einem in Verbindung mit ihm vorgesehenen Entladungsförderer 5 weiter befördert werden. Für den Kreis des Entladerahmens 2 ist ein separater, den Mantel des Silos 1 umkreisender ringförmiger Raum 8 da, in dem ein am Kreis des Entladerahmens 2 befestigter Schaber 6 die dort geflossenen Späne in den Schacht 4 befördert. Der ringförmige Raum 8 hat einen vom Boden 3 des Silos 1 separaten, weiter unten liegenden Boden 10, über welchem der Schaber 6 geht. Der ringförmige Raum 8 ist ein den Mantel 1 des Silos tragendes Element. Der untere Rand des Mantels 1 ist mit einem Stützring 9 verstärkt. Der Entladerahmen 2 wird über eine Verzahnung am Außenkreis mit zwei, vier oder sechs Druckzylindern 7 rotiert. Durch den Spalt zwischen dem Mantel 1 und dem Entladerahmen 2 sowie zwischen dem Boden 3 und dem Entladerahmen 2 fließen Späne auf den Boden 10 des ringförmigen Raums 8. Der Schaber 6 sammelt die dort geflossenen Späne und befördert sie durch den Schacht 4 an einen Entladungsförderer 5.The silo unloading device consists of a, above the bottom 3 of the silo 1 rotating unloading frame 2 , the chips fall from the silo into an underlying shaft 4 , from which the chips are conveyed further with a discharge conveyor 5 provided in connection with it. For the circle of the unloading frame 2 there is a separate annular space 8 encircling the jacket of the silo 1 , in which a scraper 6 attached to the circle of the unloading frame 2 conveys the chips that have flowed there into the shaft 4 . The annular space 8 has a bottom 10 , which is separate from the bottom 3 of the silo 1 and over which the scraper 6 passes. The annular space 8 is an element supporting the jacket 1 of the silo. The lower edge of the jacket 1 is reinforced with a support ring 9 . The unloading frame 2 is rotated via a toothing on the outer circle with two, four or six pressure cylinders 7 . Chips flow to the bottom 10 of the annular space 8 through the gap between the jacket 1 and the unloading frame 2 and between the bottom 3 and the unloading frame 2 . The scraper 6 collects the chips that have flowed there and conveys them through the shaft 4 to a discharge conveyor 5 .
