Abstract
A sample collector for aggregate material is provided. The collector includes a support frame having a first end and a second end. A pair of guide plates are attached to the first end of the support frame. These guide plates are spaced apart so as to define a collection space therebetween. At least one of the guide plates is provided with a track that extends generally along the periphery of the collection space. A flexible closing plate is disposed between the guide plates and is adapted for sliding engagement with the track, so that the closing plate may be moved between an open position which exposes the collection space and a closed position which encloses the collection space. A mechanism is also provided for sliding the closing plate between the open position and the closed position.
