Abstract:
A sampling assembly including a screw-drill machine for a container of heterogeneous solid material to be sampled, comprising:an abutment upon which a container of heterogeneous solid material to be sampled is adapted to be set,a supporter post on the abutment and including a fixation arm for locating the material container at a lower part of the post,a set of suspension arms including a rotary arm and a slide arm, the slide arm being vertically movable up and down along a guide device on an upper section of the post by a motor, the rotary arm being rotatable connected relative to and vertically movable with the slide arm,a Geneva indexer and a second motor for driving the Geneva indexer to intermittently horizontally rotate the rotary arm relative to the slide arm about a vertical axis,a screw-drill machine on the rotary arm, the screw-drill machine including a sampling tube and a screw that is adapted to be rotated in either one of a clockwise direction and a counterclockwise direction in the sampling tube, the screw-drill machine being longitudinally moved relative to the container by movement of the slide arm on the post by the first motor for sampling and discharging of material packed in the container, wherein rotation of the screw inside the sampling tube in one of a clockwise direction and a counterclockwise direction causes the material packed in the container to be one of drawn into and discharged from the sampling tube.
