This invention relates to sampling, in particular to devices for sampling from a stream of compressible bulk material.

The purpose of the invention is to increase the reliability of determining the density of the sample being taken.

FIG. 1 shows the proposed device, a general view; in fig. 2 - the same, in the position of readiness for sampling; in fig. 3 shows section A-A in FIG. 2; in fig. 4 - device in the position corresponding to the end of the sampling; in fig. 5 - the same, at the time of sample Extraction.

The device contains a guide 1, a retractable sampler 2 mounted telescopically in it, having a pointed end, a valve holder 3 with a blade-shaped divider 4 and a cone nozzle 5, discharge ports b and 7, handles 8 and 9, hole 10 of longitudinal movement of the probe 0

pressing coaxially with the hole made in it. When sampling, the rod 3 with the divider 4 is moved by the handle 9 along the groove 12. In this case, the cone nozzle 5 is inserted into the material. The groove 12 allows longitudinal axial movement of the handle 9, but excludes lateral. As a result, the divider 4 is installed in a vertical position. 1-2 seconds after insertion of the rod 3, the uniformity of the flow movement is restored, after which the sampler 2 is moved by moving the handle 8 along the groove 11. The material enclosed between the sampler 2, the end of the rod 3, the divider 4 and the cone nozzle 5 is in a closed space . The rod 3, telescopically mounted in the sampler, is retracted along with the sampler by the movement of the handle 8 to the extreme left position. At the same time unloading 0

The sampler, grooves 11 and 12, made 25 windows 7 and 6 are the same. So that in the guide 1, which is attached to the attracted sample, the rod 3 by the handle of the wall 13 of the pressing chamber, for example, by electric welding.

9 is retracted to the extreme left position. In this case, the divider 4 is installed above the discharge ports 7 and 6 and the selected material is removed to the outside.

i The cutter 3, made in the form of an Itok, has a knife-like divider and a tapered guide (nozzle) 5 1 When the stem is inserted with the help of a tapered nozzle 5 into the bulk material, the cutter-like divider 4 in this case prevents its blade from the movement of the bulk material. down), but only divides it into two streams relative to the divider. The knife-shaped divider itself is a racing partition, resulting in the measurement of a measured volume p of the shut-off valve (rod). When selecting a device, the density of the bulk material is not disturbed by the device, which increases the reliability of its determination.

The device works as follows.

The guide 1 is fixed in the chosen place of the wall of the chamber 13

The windows 7 and 6 are the same. In order to draw a drawn sample, the rod is 3 handles

9 is retracted to the extreme left position. In this case, the divider 4 is installed above the discharge ports 7 and 6 and the selected material is removed to the outside.
