BLOCKING SYSTEM FOR A HORIZONTAL DIRECTIONAL DRILLING MACHINE

摘要

A horizontal directional drilling machine (120) including a magazine (128) for holding a plurality of rods. The magazine (128) includes a plurality of columns (130a-133a) in which the rods are held. Each of the columns (130a-133a) has a separate bottom opening. A feed structure (144) is positioned beneath the magazine (128). The feed structure (144) includes a plurality of upwardly opening pockets (130b-133b) sized for receiving the rods from the columns (130a-133a). The horizontal directional drilling machine (120) further includes a blocking arrangement (146) that automatically blocks one or more of the pockets (130b-133b) of the feed structure (144).
