ABSTRACT:
A grain sampling probe device for insertion into grains comprises an elongated grain probe element which contains a plurality of openings extending along its length and a plurality of retaining brackets extending outwardly to define a passageway. Mounted integral to the grain probe is a hydraulic cylinder which is attached to a gate member, having a plurality of openings therein, which is slidably positioned within the passageway between the retaining brackets and the probe. The hydraulic cylinder selectively moves the gate member between an open position wherein the grain passes through the plurality of openings into the grain probe and a closed position wherein the openings are closed and the grain is sealed within the probe. A suction device is attached to the end of the probe to remove the collected grain after each sampling operation is completed.
