ABSTRACT:
Fumigation apparatus for placing solid fumigant in grain in ship holds, using a gas-permeable sleeve that is telescoped within an elongated tubular probe to be driven into the grain by a probe manipulator mechanism. The mechanism has three sets of drive rollers in a housing that is clamped around the lower end portion of the probe at the surface of the grain, the mechanism being releasably secured to a foldable base platform and driven by a power operator including a reversible electric motor and a reduction gear box. The sleeve is fabric, having a funnel-shaped open upper end and a closed lower end above a flap or tail for hanging out of the probe during installation. A flexible line is secured to the probe for repeated use in pulling sleeves into the probe for rapid placement of the sleeves after introduction of fumigant.
