Abstract
A method and apparatus is provided for cross-stream sampling of bulk material distributed as a mounded continuum in a trough formed along the length of a belt conveyor. A rotating cutter passes transversely through the traveling, bulk material continuum to extract substantially all material on said belt in a swath between transverse, parallel cutting planes. Proximate of the sample cutting swath, before and after such swath relative to the material traveling direction, rigid skirting is provided to overlay both lateral edges of the belt. Garlands of resiliently mounted belt supporting idlers span under the belt laterally of the swath to urge the belt into a substantially continuous line of sealed contact with the skirting. Simultaneously, the trough bight of the belt between the skirting is urged into the swath volume to require displacement from the swath volume by passage of the sample cutter thereby insuring full belt surface contact by the cutter and maximum small particle retrieval.
