ABSTRACT:
A drill and probe mechanism is adapted for use in grain bins and extends down deep into the body of grain to either retrieve a grain sample or deposit fumigation pellets. The drill portion of the mechanism includes a hydraulic pump providing power for a reversible hydraulic rotary head and separate screw. Lengths of drill string connect to the rotary head and the screw pushes the rotating drill string downward into the body of grain. A probe connected to the end of the drill string includes a tubular container body with doors that are opened and closed by selective clockwise and counter-clockwise rotation of the drill string. Various types of probes are utilized, including one that merely collects grain for sampling and another that dispenses fumigant pellets.
