| 摘要 |
A blast hole drill machine (100) including a deck frame (102), and a mast (106) mounted on the deck frame (102) is provided. A feed cylinder (120) supported on the mast (106) and configured to move in proportion to movement of a rotary drill head (114) along the mast (106). A position magnet (202) is moveably disposed on the feed cylinder (120). A linear transducer (204) extends along the mast (106) and configured to detect a movement of the position magnet (202) indicative of a change in a position of the rotary drill head (114). |
