Abstract

Zum Aufnehmen gebündelten und losen Schwachholz-Schnittgutes und seiner rationellen Zerkleinerung wird ein Vorsatz für Traktoren, Bagger und Radlader, oder Zusatz zu Ladekränen vorgeschlagen, der üblichen Greif- und Verladevorrichtungen ähnlich ist, jedoch mit hydraulischen, ineinander verschränkten Greiffingern ausgestattet ist, die das Schwachholz nach dem Anheben über dem Sammelcontainer durch überschneidendes Zusammenführen der Greiffinger zerkleinert.

For picking bundled and loose small timber cuttings and its rational comminution a header for tractors, excavators and wheel loaders, or addition to loader cranes is proposed, the usual gripping and loading devices is similar, but equipped with hydraulic, interlocking gripper fingers, the weak wood crushed after lifting over the collection container by overlapping merging the gripper fingers.

Description

BEREICH DER ERFINDUNGFIELD OF THE INVENTION

Die Erfindung befasst sich mit der Entsorgung von Schwachholzabschnitten.The invention is concerned with the disposal of weakwood sections.

HINTERGRUND DER ERFINDUNG/ ZU LÖSENDES PROBLEMBACKGROUND OF THE INVENTION / PROBLEM TO BE SOLVED

Beim Ausräumen von Hecken und Straßenbegrenzungen fallen regelmäßig größere Mengen an Abschnitten von Schwachholz an, die z.B. am Straßenrand abgelegt, danach aufgenommen und entsorgt werden müssen.When clearing hedges and road borders, larger quantities of sections of small wood regularly accumulate, e.g. deposited on the roadside, then added and disposed of.

Dabei füllen sich die zur Aufnahme bestimmten Fahrzeuge und Container durch die lockere Ansammlung von Lagen von Ästen und Zweigen schnell, wodurch die Transport- und Verarbeitungskapazität nur unzureichend genutzt werden kann.In the process, the vehicles and containers that are to be picked up quickly fill up due to the loose accumulation of layers of branches and twigs, which means that the transport and processing capacity can only be used inadequately.

STAND DER TECHNIKSTATE OF THE ART

Bisher sind keine Ladegreifer bekannt, die in der Lage sind das aufgenommene Material durch ein Verschränken der Greifvorrichtungen zu zerteilen.So far, no load grippers are known, which are able to split the recorded material by interleaving the gripping devices.

Allenfalls der in NL1006301 C2 beschrieben Bergungsgreifer für gesunkene Wasserfahrzeuge verfügt über Kanten, die in der Lage Material zu durchtrennnen, allerdings wird hier nicht das Bergegut zerschnitten und auch ein vollständiges Schließen der Greifvorrichtung ist nicht vorgesehen.At most, the in NL1006301 C2 described salvage gripper for sunken vessels has edges that are able to sever material, however, here is not the Bergegut cut and also a complete closing of the gripping device is not provided.

AUFGABE DER ERFINDUNGOBJECT OF THE INVENTION

Es ist die Aufgabe vorliegender Erfindung, die Transport- und Verarbeitungskapazität besser zu nutzen und die Verarbeitung des Schwachholzes zu rationalisieren.It is the object of the present invention to make better use of the transport and processing capacity and to rationalize the processing of small timber.

LOSUNGSOLUTION

Die gegebene Aufgabe wird dadurch gelöst, dass die zur Verladung des Schwachholzes üblichen Vorsätze für Traktoren, Radlader oder Kranaufsätze auf LKWs so ausgebildet werden, dass sie nicht nur das Schwachholz greifen um es in Behältnisse zu Abfuhr zu laden, sondern es nach dem Anheben, in einer Position über dem Behältnis. durch Zusammenfahren der Greifvorrichtung scherend zu zerteilen.The given object is achieved in that the customary for loading the small wood attachments for tractors, wheel loaders or crane attachments are designed on trucks so that they not only grab the small wood to load it into containers for discharge, but after lifting, in a position above the container. shearing by moving the gripping device together.

Zu diesem Zweck sind mehrfingerige, säbelförmige Greifvorrichtungen vorgesehen, deren Finger in zusammengefahrenen Zustand ineinander verschränkt sind und an den Flanken über Schneidekanten verfügen.For this purpose, multi-fingered, saber-shaped gripping devices are provided whose fingers are interlocked in the contracted state and have on the flanks cutting edges.

Optional können die Schneidekanten auswechselbar sein und aus gehärtetem Material, beispielsweise Stahl, bestehen.Optionally, the cutting edges may be interchangeable and made of hardened material, such as steel.

  • 1 zeigt einen Schneidgreifer (1), der über säbelartige Greiffinger (2 bis 7) mit auswechselbaren, leicht überstehenden Schneideflächen (8 bis 10) verfügt. Die jeweils vorderen und hinteren Greiffinger sind hier beispielhaft mittels Kraftübertragungsbrücken (vorne 13 und 14, hinten nicht dargestellt) miteinander verbunden, diese werden über hydraulisch betriebene Zylinder (vorne 11 und 12, hinten nicht dargestellt) bewegt. 1 shows a cutting gripper ( 1 ), about saber-type gripper fingers ( 2 to 7 ) with interchangeable, slightly protruding cutting surfaces ( 8th to 10 ). The front and rear gripper fingers are here exemplified by means of power transmission bridges (front 13 and 14 , rear not shown) connected to each other, these are hydraulically operated cylinder (front 11 and 12 , rear not shown) moves.

Die Schneidgreifer sind an Ihrer Basis über Gelenke miteinander und über einen rohrförmigen Träger (15) mit einem Sockel (16) verbunden, welcher über Verbindungsstücke (17) mit beispielsweise einem Ladekran verbunden wird.The cutting grippers are at their base via joints with each other and a tubular support ( 15 ) with a socket ( 16 ) connected by connectors ( 17 ) is connected to, for example, a loading crane.
