ABSTRACT:
The invention comprises a grain sampling device installed in a grain bin. The apparatus has a plurality of sleeves in concentric relation, with the upper ends of the sleeves adjacent the upper central portion of the bin so as to be beneath and close to the top of the grain pile when the grain pile substantially fills the grain bin. The sleeves extend downward from the top central portion at an angle and project out the wall of the bin near the bottom of the bin. Lateral pipe sections are mounted to the inner sleeve on the outside of the bin so as to serve as handles and outlets and the sleeves have openings at selected levels inside the bin including the top of the sleeves whereby by rotation of the handles from outside the bin the openings in the sleeves can align with one another at selected levels to allow grain in the bin at the selected level to gravitate into the inner sleeve through the openings and travel under a gravitational flow downward along the inner sleeve outside the bin and out a lateral section to enable a sample of grain to be obtained.
