摘要: This disclosure relates to a sampling device which includes a casing having a drilling worm or auger mounted therein and wherein there is carried by the casing for movement axially thereof a scraper, the scraper being disposed between adjacent convolutions of the drilling worm and being operable both to form a top closure for the space within the casing during the taking of a sample and to effect a thorough cleaning of the drilling worm during the discharge of a sample whereby the sample discharged from the sampling device will be a complete sample and definitive of the area of the bulk material from which the sample is taken. The automatic cleaning of the sampling device both assures a complete sample and eliminates the unnecessary later cleaning of the sampling device.
