An improved rotary sample collector

摘要

The invention relates to a sample collector apparatus ( 10 ) for collecting samples of flowable solid materials that comprises a housing ( 11 ) and a delivery opening ( 15 ) at the upper end of the housing ( 11 ) through which material to be sampled is delivered into the housing ( 11 ). A deflector ( 12 ) is located within the housing ( 11 ) and has an upper end ( 13 ) located below the delivery opening ( 15 ) and has an angled wall ( 14 ) that acts to deflect the material. A receptacle means ( 20 ) is located towards the lower edge of the deflector ( 12 ) for receiving a sample of the material flowing downwardly. The receptacle means ( 20 ) has an opening at ( 17 ) at its lower end through which the sample passes. Means 16 is provided for moving the receptacle means ( 20 ) with respect to the material flowing downwardly and a collection means ( 23 ) is located beneath the receptacle means ( 20 ) for collecting the sample from the opening ( 17 ) and a waste opening ( 26 ) is provided at the lower end of the housing ( 11 ) to discharge the portion of material not collected by the receptacle means ( 20 ). The invention provides a unique means of ensuring the random collection of a sample which is representative of the material as a whole that moves through the sample collection apparatus ( 10 ).
