DEVICE FOR SAMPLING MATERIALS WITH READY-ASSEMBLED ROTATING TUBE Russian patent published in 2011 - IPC G01N1/02 

FIELD: machine building.

SUBSTANCE: device consists of screw with blade of screw and axis of screw. The screw is designed for extraction of material from a container for material primary sampling. The device also contains the first motor mechanically coupled with axis of the screw and designed for rotation of the screw and a ready-assembled rotating tube. The rotating tube consists of an external tube wherein there is installed at least part of the screw. The external tube facilitates rotation of the screw inside the external tube and has a lower section designed for rotation. The device also includes the second engine mechanically coupled with the lower part of the external tube and designed for its rotation. The procedure consists in simultaneous rotation of the screw in the first direction and in rotation of the lower part of the external tune in the second direction, also, the first direction is opposite to the second one. Further, the sampling device is imbedded into material by means of screw and external tube rotation and sample of material is extracted from material. The sample is lifted with the screw along the external tube.

EFFECT: increased rate of sampling.
