Abstract: In sampling grain offered in bulk as shown at 40, a sampling device 10 is inserted vertically downwardly into the grain. The device 10 has an inner tube 12 having openings 18 in series along its length and a sleeve 14 which is open bottomed and axially slidable over the tube. During insertion, the sleeve 14 covers the openings 18. To obtain a sample, the sleeve 14 is slowly slid upwardly relative to the inner tube thus progressively to expose the openings 18 from the bottom upwardly. Grain flows laterally via the openings 18 into the tube, which fills from the bottom. Practically no vertical displacement of kernels takes place, thus ensuring that a representative sample is taken at all levels. Ultimately, the sleeve 14 is slid downwardly to close the openings 18. The device, containing the sample, is withdrawn.
