Definitions

  • the invention relates to a mobile soil compaction system according to claim 1, in particular a soil compaction system with a mobile working machine and an attachment tool for soil compaction.
  • Soil compaction devices such as vibratory plates or shaker plates are well known and are typically driven by combustion engines in construction sites to provide high performance independently of a power source from a power grid or a generator.
  • Mobile work machines are also known and can be used, for example, as wheel loaders, telescopic handlers, or excavators.
  • Such work machines have a vehicle frame and a chassis that supports the frame for moving it. They also have a drive system, such as a hydraulic drive, which can serve both as a drive for travel and as a drive for working.
  • soil compaction devices for such machinery, enabling the machinery to also be used for soil compaction.
  • These soil compaction devices are also known as attachment or plate compactors and are generally hydraulically operated.
  • a hydraulic motor is provided on the attachment compactor, which serves as the implement.
  • This motor is supplied by the machinery's hydraulic system and drives an unbalanced exciter belonging to the attachment compactor.
  • the resulting centrifugal or vibrational forces are transmitted to a soil contact plate, which compacts the soil to be compacted. By moving the machinery, the soil can thus be compacted over a larger area.
  • Hydraulically driven compactors have poor efficiency and controllability.
  • the frequent connecting and disconnecting of the hydraulic drive poses a risk of hydraulic oil leakage and environmental damage.
  • a known excavator is equipped with a detachably attached compactor attachment.
  • the compactor attachment is hydraulically driven.
  • Sensors or signaling devices of the compactor attachment can be connected via Electrical connecting cables are connected to the excavator's on-board electrical system.
  • the invention is based on the objective of providing an attachment tool and a soil compaction system utilizing the attachment tool, with which the disadvantages of the prior art can be overcome.
  • a mobile soil compaction system according to claim 1, comprising a mobile work machine with an attachment tool for mounting on the work machine.
  • Advantageous embodiments are specified in the dependent claims.
  • a tool attachment for mounting on a working machine comprising a ground contact plate for compacting soil, an unbalance exciter that applies unbalance forces to the ground contact plate, an electric drive for powering the unbalance exciter, a mechanical coupling device for connecting the tool attachment to the working machine, and an electrical power interface for connecting to an electrical power supply.
  • the attachment is essentially a soil compaction device, such as a plate compactor.
  • the attachment is electrically driven by an electric drive, in particular an electric motor.

Rather, synchronization occurs automatically through self-synchronization.
