Abstract
A device for systematic sampling coarse material sliding down an inclined chute. A bottom portion of the chute is removed and replaced by a sampling device mounted below the chute opening. The sampling device includes a drum for receiving the sample, a gate mounted to the bottom of the chute for rotation between open and closed positions and a motor for rotating the drum. The outer surface of the drum is provided with an opening. The drum is rotated until the drum opening is aligned with the chute opening causing the gate to be rotated to its open position. Material is diverted from the chute into the drum. After the sample is obtained, rotation of the drum is continued until the gate is closed so that the material continues to slide down the chute without passing into the drum.
