Apparatus for drawing a sample of grain from a stream of grain flowing along a path is described in which a tube extends into the grain flow path for diverting a portion of the flowing grain along the path to a sample collection station. The diverter diverts only a portion of the grain flowing along the path and the balance of the grain flowing along said sampling path is permitted to flow. A collector is provided for collecting at least a portion of the grain flowing to the sample collection station so as to accumulate grain for a sample that is representative of all of the grain flowing along the path for the time that the grain is being collected for the sample.

Apparatus of the present invention for batch drying crop in the shell comprises a bin having a generally cylindric bin wall, a conical upper drying floor carded by the bin wall, means floor for forming a substantially uniform layer of the crop to be dried on the upper surface of the upper drying floor, and selectively operable means for effecting the gravity discharge of the batch of crop from the upper drying floor. An inverted conical lower drying floor is carded by the bin below the upper drying floor for receiving the crop discharged from the upper drying floor. The lower drying floor has a hopper shaped crop supporting surface. Means is associated with the lower drying floor for forming a substantially uniform layer of crop on the lower drying floor upon the crop being gravity discharged from the upper drying floor. The lower drying floor further has a bottom outlet for the gravity discharge of the crop supported thereon. The upper and lower drying floors are of perforate construction so as to permit air under pressure to flow therethrough and through the layer of crop supported thereon.

An improved latching apparatus for an access opening cover member or door on a grain bin. When locked closed, the cover member engages the adjacent wall of the grain bin to integrate the cover member with the grain bin wall to thereby enable hoop stresses caused by the weight of grain being stored in the bin to pass through the cover member. Typically, a series of pins carried by the door frame engages openings in the edges of the cover member or door to structurally integrate the door into the bin. The integration of the cover member with the bin wall provides a greater structural integrity of the bin and cover member; however, due to the stresses placed upon the cover member and bin wall, the pins tend to bind, making it difficult to disengage and open the cover member. In order to help disengage the cover member from the adjacent bin wall, the latching apparatus includes cam means for providing a mechanical advantage to force the cover member out of engagement with the pins and thereby permit the cover member to open with reduced effort. Improved pin structure is also disclosed.
