ABSTRACT:
A sample collecting method comprises advancing a baffle member to a position beneath the delivery end of an upstream main belt conveyor continuously conveying a material, advancing a collecting belt conveyor to a position beneath the baffle member, retracting the baffle member to permit transfer of a portion of the material from the main belt conveyor onto the collecting belt conveyor, advancing the baffle member again to terminate the transfer of the material from the main belt conveyor onto the collecting belt conveyor, stopping the collecting belt conveyor at the same time, and running the collecting belt conveyor in the opposite direction at low speed to collect as a sample an intermediate adequate portion of the mass of the material transferred onto the collecting belt conveyor.
