Abstract
The present disclosure provides an excavation machine that is configured to minimize or otherwise account for the unintended stoppage (i.e., jamming/stalling) of a digger tool. According to an embodiment of the present disclosure a machine is provided with one or more drive systems that automatically stop and reverse to avoid excavation tool jamming. The machine and methods of the present disclosure provide an efficient method and machine for excavation operations.
Claims22
1-27. (canceled)
An excavation machine comprising:
- a chassis supported on propulsion structures that are part of a ground drive system for propelling the chassis over a ground surface;
- an excavation attachment carried by the chassis, the excavation attachment including a digging tool including a plurality of cutting teeth driven by an attachment drive system;
- an actuator for raising and lowering the excavation attachment relative to the chassis;
- an electronic control system configured to trigger an auto reverse sequence when an auto reverse trigger condition is detected, wherein the auto reverse sequence includes an action selected from the group consisting of:
- a) automatically reversing the ground drive system to move the chassis and the excavation attachment carried by the chassis in a reverse direction;
- and b) automatically reversing the attachment drive system to reverse a cutting motion of the cutting teeth of the digging tool.
A machine for excavating comprising:
- a chassis supported on propulsion structures that are part of a ground drive system for propelling the chassis over a ground surface;
- an excavation tool carried by the chassis, the excavation tool being selected from the group consisting of a chain, a wheel, and a drum;
- an excavation tool drive system for rotating the excavation tool;
- a control system configured to detect an auto reverse trigger condition and trigger an auto reverse sequence when the auto reverse trigger condition is detected, wherein the auto reverse sequence includes automatically reversing the excavation tool drive system to reverse a direction of rotation of the excavation tool from the first rotational direction to a second rotational direction that is opposite from the first rotational direction.
An excavation machine comprising:
- a chassis supported on propulsion structures that are part of a ground drive system configured to propel the chassis over a ground surface;
- an excavation tool carried by the chassis, the excavation machine including an excavation tool drive system configured to drive the excavation tool in a cutting motion;
- a control system configured to detect an auto reverse trigger condition and trigger an auto reverse sequence when the auto reverse trigger condition is detected, wherein the auto reverse sequence includes automatically reversing the ground drive system to move the chassis and the excavation tool carried by the chassis in a reverse direction.
An excavation machine comprising:
- a control system configured to:
- engage an excavation tool with the material to be excavated by lowering an excavation tool to engage the ground;
- move the excavation tool relative to the material to be excavated by activating a ground drive;
- and trigger an auto reverse sequence based on the detection of an auto reverse trigger condition, wherein the auto reverse sequence includes automatically reversing the ground drive system.
