Problems solved by technology

Locking notches require a lot of space in the joint configuration
Additionally, after multiple engagements, the locking notch becomes damaged or can allow play, which can cause fluid to leak between the couplings
However, without the locking notch, the actuator would have to withstand the considerable force exerted by the pressurized fluid flowing through the circuit, which would cause the coupler to disengage.

Embodiment Construction

[0019] The present invention generally relates to a coupling arrangement 10 for coupling a machine hydraulic fluid circuit to a work tool hydraulic fluid circuit.

[0020] figure 1 Shown is a main machine 1 as a hydraulic excavator, which may be provided with a hydraulic boom mechanism for driving a boom 2 and a working tool 3 . In this description, the boom 2 may be understood to include a hydraulic boom mechanism, or similar.

[0021] Machine 1 may be a mobile machine such as an excavator, backhoe, backhoe, loader, knuckle loader, harvester or forestry machine.

[0022] Work tool 3 may be coupled to machine 1 via boom 2 . In the illustrated embodiment, the work tool 3 may comprise a rotary cutter. In other embodiments, the working tool 3 may include, for example, a bucket, a grab, a weight, and a pulverizer.

[0023] Work tool 3 may include a frame carrying a plurality of interchangeable and / or swappable tools.

[0024] The machine 1 can be provided with a coupling arr...

Abstract

A coupling arrangement (10) for fluid coupling a work tool (3) to a machine (1) comprising a plurality of coupler assemblies (24) slideably mounted in a plurality of corresponding cavities (16) for coupling a machine fluid circuit and a work tool fluid circuit, the coupler assemblies (24) partitioning the cavities (16) to form chambers (26); and a rail circuit (13) connecting the chambers (26).

Description

technical field [0001] The present invention relates to a coupling arrangement, and more particularly to a coupling arrangement for coupling a work tool to a machine. Background technique [0002] A work tool, such as a shear, grab, or bucket, may be coupled with a host machine, such as an excavator, to perform a work operation such as cutting, grabbing, or digging. The work tool may be coupled to the boom or boom mechanism of the host machine via a fixed connection or a quick release connection. [0003] The quick release connection allows for relatively easy change of work tools whereby an operator can connect or change a work tool without leaving the cab. The mechanical mounting bracket is configured to slide into the work tool mounting bracket when the work tool is positioned on the ground. After the mounting bracket of the work tool and the mounting bracket of the machine are aligned, the locking device may be moved to a locked position to lock the work tool to the ma...
