Definitions
- the invention relates to a soil compacting device, which can be fastened by means of a quick-change device on the arm of the excavator or the like.
- soil compacting devices such as those from the DE 201 05 427 U1 are known, characterized in that they can be extremely quickly and effortlessly mounted on an excavator or the like and when not in use just as easily dismantled and replaced with another tool. Since the soil compactor is controlled by the hydraulic control of the excavator, only a few adjustments, for example a rotation about a vertical axis can be made in the known soil compactors. However, setting the soil compactor to the respective soil conditions is not possible.
- Fig. 2 shows a detailed view of the roller body 11 of the soil compaction device 10 from Fig. 1 in partially cut condition.
- a motor 15 of a vibration generator 30, which is integrated in the roller body 11 and thus protected on all sides and not shown here eccentrically mounted weight, which is also integrated in the roller body 11, shown.
- the arrangement of the imbalance weight in the roller body 11 allows an optimal introduction of force to the soil to be compacted.
- the eccentricity of the weight be adjustable, so that the amplitude generated, the vibrations generated can be varied.
- the frequency of the oscillator 30 can also be varied.

Description
Die Erfindung betrifft eine Bodenverdichtungsvorrichtung, die mittels einer Schnellwechseleinrichtung am Arm des Baggers oder dergleichen befestigbar ist. Solche Bodenverdichtungsvorrichtungen, wie sie beispielsweise aus der
Aus der
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen an einen Bagger oder dergleichen anbaubaren Bodenverdichter zu schaffen, dessen Schwingungen mindestens besser als bei den bekannten Verdichtern an die jeweiligen Bodengegebenheiten anpassbar sind.The present invention has for its object to provide an attachable to an excavator or the like soil compactor whose vibrations are at least better than in the known compressors to the respective soil conditions customizable.
Die Aufgabe wird mit einer Bodenverdichtungsvorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Durch die Verstellbarkeit der Exzentrizität ist die Amplitude des Schwingungserzeugers einstellbar. Die Verstellung des Unwuchtgewichts kann beispielsweise allein durch die Fliehkraft bei Überschreiten einer bestimmten Drehzahl erfolgen. Dabei kann die Exzentrizität stufenlos oder auch zwischen zwei Endstellungen verstellbar sein.The object is achieved with a soil compaction device having the features of claim 1. Due to the adjustability of the eccentricity, the amplitude of the vibrator is adjustable. The adjustment of the imbalance weight can for example be done solely by the centrifugal force at a certain speed is exceeded. In this case, the eccentricity can be adjusted continuously or between two end positions.
Auch die Frequenz des Schwingungserzeugers ist bei der erfindungsgemäßen Vorrichtung verstellbar. Dies erfolgt dadurch, dass ein Hydraulikventil vorgesehen ist, das die Öldurchflussmenge durch den Erregerantrieb steuert. Zur Verstellung der Frequenz des Schwingungserzeugers sind somit keine elektrischen Einrichtungen erforderlich. Die Einstellung der Frequenz kann allein mittels der Hydraulikvorrichtung des Baggers durchgeführt werden.The frequency of the vibrator is adjustable in the device according to the invention. This is done by providing a hydraulic valve that controls the oil flow rate through the exciter drive. To adjust the frequency of the vibrator thus no electrical equipment is required. The adjustment of the frequency can be carried out solely by means of the hydraulic device of the excavator.
Weitere Vorteile ergeben sich, wenn der Schwingungserzeuger eine zweite Welle mit einem exzentrisch gelagerten Gewicht zur Erzeugung gerichteter Schwingungen aufweist. Auf diese Weise ist auch ein selbsttätiges Vorwärtsbewegen des Schwingungserzeugers möglich. Durch Umkehr der Rotationsrichtung der Wellen kann auch die Bewegungsrichtung umgekehrt werden.Further advantages result if the vibration generator has a second shaft with an eccentrically mounted weight for generating directed vibrations. In this way, an automatic forward movement of the vibrator is possible. By reversing the direction of rotation of the waves and the direction of movement can be reversed.
Bei einer bevorzugten Ausführungsform kann die Schnellwechseleinrichtung außerdem ein Drehlager aufweisen, das ein Verschwenken der Bodenverdichtungsvorrichtung um 360° erlaubt. Die Verdichtungsvorrichtung ist dann optimal an die jeweiligen räumlichen Gegebenheiten anpassbar.In a preferred embodiment, the quick-change device can also have a pivot bearing, which allows pivoting of the soil compacting device by 360 °. The compacting device is then optimally adaptable to the respective spatial conditions.
Für das rasche Montieren und Demontieren der Verdichtungsvorrichtung ist es außerdem von Vorteil, wenn die Schnellwechseleinrichtung Durchführungen für Hydrauliköl oder Druckluft zur Ansteuerung und zum Antrieb der Bodenverdichtungsvorrichtung ... aufweist. Dabei können beim Ankoppeln der Schnellwechseleinrichtung an den Baggerarm die Hydraulik- oder Druckluftanschlüsse zur Bodenverdichtungsvorrichtung automatisch geschlossen werden.For rapid assembly and disassembly of the compacting device, it is also advantageous if the quick-change device bushings for hydraulic oil or compressed air for controlling and driving the soil compacting device ... having. When connecting the quick-change device to the excavator arm, the hydraulic or compressed-air connections to the soil compacting device can be automatically closed.
Die Bodenverdichtungsvorrichtung kann beispielsweise ein Walzenverdichter oder ein Plattenverdichter sein. Bei der Ausgestaltung als Walzenverdichter ist es von Vorteil, wenn der Schwingungserzeuger des Walzenverdichters im Walzenkörper integriert ist. Dadurch ist das Unwuchtgewicht vor Beschädigungen geschützt. Außerdem ist die Krafteinleitung des exzentrisch gelagerten Gewichts auf das Erdreich bei der integrierten Anordnung im Walzenkörper günstiger als bei einer Anordnung des Unwuchtgewichts oberhalb des Walzenkörpers, wie dies bei den Anbauverdichtern nach dem Stand der Technik der Fall ist.The soil compacting device may be, for example, a roller compactor or a plate compactor. In the embodiment as a roller compressor, it is advantageous if the vibration generator of the roller compressor is integrated in the roller body. As a result, the unbalance weight is protected from damage. In addition, the introduction of force of the eccentrically mounted weight to the soil in the integrated arrangement in the roller body is more favorable than in an arrangement of the imbalance weight above the roller body, as is the case with the cultivation compressors according to the prior art.
Zusätzlich zum exzentrisch gelagerten Unwuchtgewicht kann auch der Motor des Schwingungserzeugers im Walzenkörper geschützt und Platz sparend angeordnet sein.In addition to the eccentrically mounted imbalance weight and the engine of the vibrator can be protected in the roll body and arranged to save space.
Weitere Vorteile ergeben sich, wenn die Ölleitungen für den Motor des Schwingungserzeugers zentral im Walzenkörper nach oben zum Anschluss an die Schnellwechseleinrichtung geführt sind. Bei den bekannten Anbauverdichtern laufen die Ölleitungen seitlich am Walzenkörper entlang, wo sie leicht beschädigt werden können. Bei einer zentralen Führung der Ölleitungen wird diese Gefahr vermieden.Further advantages arise when the oil lines for the engine of the vibrator are guided centrally in the roll body up to the connection to the quick-change device. In the known cultivation compressors, the oil lines run along the side of the roll body where they can easily be damaged. With a central management of the oil lines this danger is avoided.
