Abstract
A method includes: determining a mast angle of a drilling implement, calculating the optimized hoisting speed for a drilling implement based on the mast angle or calculating the optimized drill rotation speed based on the mast angle, and hoisting the drilling implement at the optimized hoisting speed if desired, or rotating the drill at the optimized drill rotation speed if desired.
Claims20
A machine comprising:
- a frame;
- at least two ground engaging propulsion elements coupled to the frame;
- a drilling implement including a drill and a mast, defining a longitudinal axis movable relative to the frame and a vertical axis from a vertical position to an inclined position forming a mast angle that is greater than zero degrees measured from the vertical axis to the longitudinal axis in a plane containing the longitudinal axis and the vertical axis;
- a rotary drilling mechanism operatively coupled to the drill;
- a first monitoring mechanism configured to indicate the mast angle;
- a second monitoring mechanism configured to indicate a hoisting speed of the hoisting mechanism;
- a third monitoring mechanism configured to indicate a drill rotation speed;
- a control unit coupled to the first monitoring mechanism, the second monitoring mechanism, and the third monitoring mechanism;
- wherein the control unit is configured to:
- determine a maximum hoisting speed of the hoisting mechanism, determine the current hoisting speed of the hoisting mechanism, and command a change to the current hoisting speed of the hoisting mechanism if the current hoisting speed is at the maximum hoisting speed, and if the mast angle is greater than zero;
- or
- determine a maximum drill rotation speed of the rotary drilling mechanism, determine the current drill rotation speed of the rotary drilling mechanism, and command a change to the current drill rotation speed if the current drill rotation speed is at the maximum drill rotation speed, and if the mast angle is greater than zero.

- or
- determine a desired drill rotation speed, determine a current drill rotation speed, and
- command a change to the current drill rotation speed if the current drill rotation speed is not the same as the desired drill rotation speed.
