ABSTRACT:
A wood chip sampling apparatus which includes a chip collecting tray. The tray moves to a first location where it collects a sample of downwardly flowing wood chips and then to a second location where it discharges the chips into a chip sample bin for later analysis. The tray is pivoted about a horizontal axis and is weighted on one side of the pivot axis so that it automatically assumes a horizontal, chip receiving orientation after chip discharge. An abutment prevents the tray from pivotting and dumping collected chips in the first tray location, the tray automatically pivotting to dump the chips when in the second location. The collecting tray thus reciprocates along a horizontal path and pivots over a range of 90 degrees.
