Abstract
A universal coupler for a backhoe assembly in which a first link is pivotally connected to the articulation joints of the backhoe assembly. Mounting holes for a first and third style bucket with equal pin spacing are provided on the first link. A second link is connected to the first position and is pivotal between a first position in which the mounting holes are exposed and a second position in which the second link covers the holes on the first link and provides the mounting hole diameter and pin spacing for a bucket having a greater pin spacing.
Claims17
A universal coupler for connecting multiple style buckets to the articulation joints of a single style work machine, said coupler comprising:
- at least a first link having a mounting hole at one end for connecting with a pivotal support on the work machine, said link having a hook section for receiving one of multiple styles of buckets;
- a second link connected to said first link and pivotal between first and second positions around a pivot axis, the first position of said second link exposing a first mounting hole and spacing for corresponding mounting holes on a first style of bucket having aligned mounting holes with a spacing dependent upon the first link, and a second position of said second link completely covering said first mounting hole, said second link having a second mounting hole and spacing for corresponding mounting holes on a second style of bucket having aligned holes with spacing dependent upon said second link;
- wherein the pivot axis and an axis of the second mounting hole are separate axes.
A work machine comprising mounting points for articulated movement of a bucket, said links including a pivotal link and a second link for movement relative to said pivotal link;
- a universal coupler for connecting multiple style buckets to the articulation joints, said coupler comprising at least a first link having a mounting hole at one end for connecting with the pivot support on the work machine, said link having a hook section for securing one of multiple styles of buckets;
- a second link connected to said first link and pivotal between first and second positions around a pivot axis, first position of said second link exposing a first mounting hole and spacing for corresponding mounting holes on a first style of bucket having aligned mounting holes with a spacing dependent up on the first link, the second position of said link completely covering said first mounting hole, said second link having a second mounting hole and spacing for corresponding mounting holes of a second style of bucket having aligned mounting holes with a spacing dependent upon said second link;
- and,
- a bucket of a given style received in the C-shaped slot and mounted to its respective mounting holes by a pin;
- wherein the pivot axis and an axis of the second mounting hole are separate axes.
