Work tool attachment for a work machine
A work machine comprising a frame and a ground-engaging mechanism, the ground-engaging mechanism configured to support the frame on a surface, a boom assembly coupled to the frame, the boom assembly having a pair of boom arms pivotally coupled to the frame and moveable relative to the frame by a pair of boom hydraulic cylinders, an attachment coupler coupled to a distal section of the boom arms, and an attachment. The attachment comprises a work tool. The work tool is coupled to the C-frame. A pair of first C-frame sections are pivotally coupled to the frame of the work machine, and a second C-frame section is pivotally coupled to the attachment coupler, wherein actuating the pair of boom hydraulic cylinders engages the boom arms, pitching the attachment upwards or downwards.
1. A work machine, comprising:
a frame and a ground-engaging mechanism, the ground-engaging mechanism configured to support the frame on a surface;
a boom assembly coupled to the frame, the boom assembly having a pair of boom arms pivotally coupled to a rear-end portion of the frame and moveable relative to the frame by a pair of boom hydraulic cylinders;
an attachment coupler, the attachment coupler coupled to a distal section of the boom arms; and
an attachment comprising a work tool, a C-frame, the work tool coupled to the C-frame, a pair of first C-frame sections pivotally coupled to the frame of the work machine, and a second C-frame section pivotally coupled to the attachment coupler,
the attachment further comprising auxiliary hydraulic cylinders, wherein actuating the auxiliary hydraulic cylinders performs tilting of the work tool relative to the work machine in a direction of roll about a forward portion of the boom assembly, and angling of the work tool relative to the work machine in a direction of yaw about the forward portion of the boom assembly; and
wherein actuating the pair of boom hydraulic cylinders engages the boom arms, pitching the attachment upwards or downwards while each first C-frame section is pivotally coupled to the frame with the releasable coupling.
2. The work machine of claim 1 , wherein the pair of first C-frame sections is pivotally coupled to a track frame of the frame.
3. The work machine of claim 1 , wherein the pair of first C-frame sections is pivotally coupled to a mainframe of the frame.
4. The work machine of claim 1 , wherein the releasable coupling comprises a bolt block assembly, the bolt block assembly comprising one or more of a male coupling and a female coupling to engage one or more of a male coupling counterpart and a female coupling counterpart.
5. The work machine of claim 1 wherein the work tool is a blade.
6. The work machine of claim 1 , wherein the second C-frame section is pivotally coupled to the attachment coupler with a lifting linkage, wherein the lifting linkage is coupled to the second C-frame section on a first lifting linkage section of the lifting linkage and coupled to the attachment coupler on a second lifting linkage section of the lifting linkage.
