Abstract
A connection assembly for mounting a ground engaging tool to earthmoving equipment includes a body into which is received a resilient member, a force applying member, a locking member with an O-ring seal to be received in an annular channel around the locking member, a locking member stop received in a hole in the locking member, and a body stop to be fitted into an aperture under the body. The locking member stop prevents the force applying member from rotating within the body when the bolt is rotated and advances the piston by threaded engagement.
Claims35
A connection device to attach a ground engaging tool to earthmoving equipment, the device comprising an assembly of a body, a force applying member and a locking member having a first portion, the assembly being received into a recess in the ground engaging tool, wherein, in use, application of force by the force applying member causes a force receiving member to advance relative to the body and thereby to engage the device with a portion of the earthmoving equipment to apply forces to the ground engaging tool and the portion of the earthmoving equipment to connect the ground engaging tool to the earthmoving equipment, the locking member including means to apply a release force to the portion of the earthmoving equipment when releasing the connection device, and a stop arranged to restrict or prevent rotation of the locking member during at least one of actuation and release of the connection device.
A connection assembly to releasably attach a ground engaging tool to earth moving equipment, the connection assembly comprising:
- a body;
- a force applying member;
- and
- a locking member, the locking member being arranged to advance relative to the body for the connection assembly to retain the ground engaging tool to the earthmoving equipment and to retract relative to the body when releasing the connection assembly, the locking member including a first portion arranged to positively engage with a boss on the earthmoving equipment when the locking member retracts during a release of the connection assembly and a stop arranged to restrict or prevent rotation of the locking member during at least one of actuation and release of the connection assembly.
Components for releasably attaching a ground engaging tool to earthmoving equipment, the components comprising a connection assembly, the connection assembly including a body, a force applying member, and a locking member, the locking member being arranged to advance relative to the body for the connection assembly to retain the ground engaging tool to the earthmoving equipment and to retract relative to the body when releasing the connection assembly, the locking member including a first portion arranged to positively engage with a boss on the earthmoving equipment when the locking member retracts during a release of the connection assembly, a spacer at a rear of the connection assembly, and a stop arranged to restrict or prevent rotation of the locking member during at least one of actuation and release of the connection assembly.
A method of releasing a ground engaging tool from earthmoving equipment, the method including the steps of:
- providing a connection assembly for releasably attaching the ground engaging tool to the earthmoving equipment, the connection assembly including a body, a force applying member, and a locking member, the locking member being arranged to advance relative to the body for the connection assembly to retain the ground engaging tool to the earthmoving equipment and to retract relative to the body when releasing the connection assembly, the locking member including a first portion arranged to positively engage with a boss on the earthmoving equipment when the locking member retracts during a release of the connection assembly, a spacer at a rear of the connection assembly, and a stop arranged to restrict or prevent rotation of the locking member during at least one of actuation and release of the connection assembly;
- and
- releasing the connection assembly releasably attaching the ground engaging tool to the earthmoving equipment, wherein during the releasing the connection assembly positively retracts together the locking member and the body to contract the connection assembly.
