Benefits of technology

The present invention allows a tool to be attached to an arm of an excavator using spaced apart mounting parts. This attachment mechanism includes pick-up pins, bushes, fasteners, and retainers. These parts work together to allow for different spacing between the pick-up pins, based on the axial orientation of the bushes in relation to the surround. The technical effect is that this invention enables versatility in the attachment of tools to arms, making it easier to use with different spacing of mounting parts.

Problems solved by technology

Thus a tool from one manufacturer is generally not usable on the excavator of another manufacture.

Embodiment Construction

[0029]Referring to FIG. 1, there is shown a tool attachment 10 attached to a tool 12. In this embodiment the tool 12 is in the form of a grapple. In other embodiment the tool may be a different type of tool, such as for example a bucket. The grapple comprises a ripper or finger part 14 and an opposable, pivotable jaw 16, comprising two fingers. The jaw 16 is pivotable about pivot axis 18. The jaw 16 is actuated by a ram pivotally attached at pivot 20.

[0030]The part 14 has a mounting part comprising two spaced apart plates 24 extending orthogonal to the plane of operation of the fingers of the part 14. These plates each have two spaced apart holes 26 and 28, where the holes 26 of one plate 22 are aligned with the holes 28 of the other plate 24 to receive pick-up pins 32 and 34. Commonly a standard bush will be used to couple the pick-up pins to the plates. In the present invention the standard bushes are removed.

[0031]The tool attachment 10 comprises a plurality of pick-up pins, in t...

Abstract

A tool attachment 10 comprising a plurality of pick-up pins 32, 34 or excavator bucket pins, each for threading through a pair of spaced apart holes 26 in a mounting part 22 of the tool, a bush 40 for each hole 26, fasteners 44 for fastening each bush to a surround of the respective hole and retainers 46 for each end of each pick-up pin 32, 34, wherein each of the bushes 40 has an eccentric hole 58 there through for receiving a portion of one of the pick-up pins 32, 34 so that the spacing between the pick-up pins 32, 34 can be selected according to the axial orientation of the bushes 40 in relation to the surround 22.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This applications claims priority to and the benefit of Australian Patent Application No. 2016901849, which was filed May 18, 2016 and titled “A Tool Attachment.” The contents of the above-captioned Australian Application are relied upon and incorporated herein by reference in their entirety.FIELD OF THE INVENTION[0002]The present invention relates to an attachment mechanism for attaching a tool to the arm configuration of an excavating machine.BACKGROUND[0003]Hydraulic excavating machines are well known. They essentially comprise a power plant mounted to a movable frame. Commonly a track system is used to allow movement of the frame. The power plant is commonly rotatable with respect to the track system, but this need not be the case. A mechanical arm configuration is mounted to the power plant so that a tool can be positioned and operated. There are various types of tool that can be attached to the end of the arm, such as for example a ...
