Abstract
A method and apparatus are provided for cross-stream sampling of bulk material on a belt conveyor. The cross-stream sampling apparatus disclosed includes sample taking elements movable across the conveyor for removing a cross-stream increment of bulk material and contour elements for modulating the normal troughing of the conveyor belt and supporting and conforming the conveyor belt to the operative course of the sample taking elements as it moves across the conveyor belt. One form of the method includes segregating a cross-stream sample increment of the bulk material and sweeping the segregated increment from the conveyor belt and supporting and conforming the conveyor belt to the operative course of segregation and sweeping.
Claims14
In combination with a belt conveyor having a conveyor belt for conveying bulk material disposed thereon and drive means for said belt, sample taking means movable across said conveyor belt for removing a cross-stream increment of bulk material therefrom, said sample taking means including plate means for segregating therebetween a cross-stream increment of bulk material as disposed on said conveyor belt and impeller means for removing the thus segregated cross-stream increment of bulk material from said conveyor belt, and contour means for modulating the normal troughing of said conveyor belt and supporting and conforming said conveyor belt to the operative course of said sample taking means as it moves across said conveyor belt.
The method of taking a cross-stream sample increment of bulk material from a conveyor belt and which consists in segregating such increment, sweeping the thus segregated increment from the conveyor belt and supporting and conforming the conveyor belt to the operative course of segregation and sweeping of the increment from the conveyor belt during operation thereof.
In apparatus for removing samples of bulk material from the conveyor belt of a belt conveyor, the combination of plate means operative to segregate therebetween a cross-stream increment of bulk material as disposed on said conveyor belt, impeller means operative to remove the thus segregated increment of bulk material from said conveyor belt, and contour means for supporting and conforming said conveyor to the operative course of said plate means and said impeller means.
