Embodiment Construction

[0043] As described above, the present invention relates to a ground compacting device designed as a vibratory compacting plate, the constructional concept of which is known in principle. The basic building block of a vibratory compaction plate is a vibration exciter device, which introduces a directional vibration into a ground-contacting plate. The vibrating ground contact plate acts into the ground to compact it. In addition, the resultant total force generated by the vibration exciter means enables a longitudinal or transverse forward movement and an actuation of the vibratory tamper plate. Since this structural concept has been known in principle for a long time, a more detailed description is superfluous.

[0044] The vibratory tamper plate according to the invention has a vibration exciter arrangement with at least two individual exciters 13 which act on a ground contact plate 12 .

Abstract

A vibrating plate comprises an upper mass with a drive, a lower mass with a soil contact plate (12), and a vibration generator device, which belongs to the lower mass and which acts upon the soil contact plate (12). The vibration generator device comprises at least two individual exciters (13) each having an unbalanced shaft (2). The individual exciters (13) can be individually controlled with regard to the rotational speed and / or phase position of the respectively assigned unbalanced shaft (2). A mechanical coupling of the unbalanced shafts (2) is thus unnecessary. The unbalanced shaft (2) of an individual exciter (3) can be rotationally driven by a hydraulic motor (4). The position of the unbalanced shaft (2) is determined in at least one position by a position indicator (7).

Description

technical field [0001] The invention relates to a vibratory compaction plate. Background technique [0002] Vibrating tamping plates are known and basically consist of a lower mass (part) with a ground contact plate and an upper mass (part) elastically movably connected to the lower mass (part) and having a drive (for example an internal combustion engine or electric motor). Quality (pieces). The drive device can drive a vibration exciter device belonging to the lower mass, which acts on the ground contact plate. [0003] A so-called single-shaft exciter or traction vibration exciter is known as a vibration exciter device, in which the drive device rotatably drives an unbalanced shaft carrying an unbalanced mass. As it pivots, the unbalanced shaft pulls the ground contact plate upwards and forwards to achieve a forward movement. The ground contact plate is thus pressed downwards by the action of the unbalanced shaft and hits the ground to be compacted. [0004] In the ca...
