<p>Sampling apparatus comprises a sample ladle (1) which is able to be positioned in a horizontal (x, y) plane intersecting a stream of falling material, by orthogonal linear drive units (2, 3). The ladle (1) is pivotally mounted, and is normally retracted to an inclined position under a shroud (6). A third linear drive unit (12) is connected to the ladle (1) by a linkage (13). Upon activation of the linear drive unit (12), the sample ladle (1) is pivoted into a vertical orientation at which the ladle mouth is aligned with an opening in the shroud, enabling the ladle to receive a sample of the falling material. The third linear drive unit (12) then retracts the ladle beneath the shroud (6), and the orthogonal drive units (2, 3) move the ladle outside the falling stream of material to a discharge compartment (8), where the contents of the ladle are discharged by inversion.</p> |
