Description

The invention relates to the field of research and analysis of materials, namely, devices for sampling grain, seeds and other bulk materials from the embankment, and can be used in elevators, feed mills, collection and storage points for grain, seeds and other bulk materials.

The purpose of the invention is to increase the representativeness of the sample by expanding the sampling horizon and reducing damage to the material to be sampled, as well as reducing the labor intensity of sampling.

The sampler contains a spring rod with a working body for sampling, consisting of several cones rigidly mounted on movable sleeves. The bushings are movable in the axial direction and are connected by flexible joints between each other, which limits them in relative mixing (each cone-shaped grip is made of

SS

plates (ribs), fixed at the apex of the cone and springy-connected by nature, are elastic w (folding-sh) foams. This allows, when the sampler is immersed in an embankment, to reduce its cross section by pressing the plates and membranes against the rod under the pressure of bulk material, and when the sampler moves backward, opening occurs (due to disintegration of the bulk material) and filling the cone-shaped grips. (ribs) of the cone-shaped grippers from oil-resistant and afryktsionny cartels, for example, from caprone, increases the reliability of operation of the sampler expressed in the resistance of the material to separation NIJ oils vschel Yu- schimis from damaged seeds of oilseeds. On the membranes at the base of the cone, holes are made, the size of which is slightly less than the average diameter of the coarse fraction of the analyzed material. The presence of these holes contributes to the representative of the kocTK sample, since through them there is a small fraction of residues from the residues of the fines fraction.

The transverse mustache is mounted above the upper cone-shaped grip. (for example, plates without membranes) attached to the upper sleeve. They loosen hard-to-flow or flattened material and thus facilitate the removal of the sampler.

The part of the rod, the cone-shaped grip adjacent to it, can be made and used as a container for working cleaning the sampler during transportation with.

The lower cone-shaped grip is removable. With the release of a sample of fine-flowing material from the sampler, it is enough to remove it, and the sample is poured through the holes at the tips of the cones. If the material under study is difficult to flow, then to pour the sample through the upper open part of the cone, it is necessary to put the sample on Part of the sampler case collection, located (at

FIG. 1 shows the sampler; general view; the sleeves are provided with flexible connections; the agitating antennae are fixed on the upper sleeve; in fig. 2, - conical (funnel-shaped) working body with two types of holes; on fkg. 3 - sampler in the covered state, general view; in fig. V - case for removing the sampler.

The sampler contains a handle 1 attached to the upper sleeve 2 (or extension 3), which, together with other similar sleeves, is movably mounted on an elastic rod 4. The sleeves 2 are connected between each other with flexible threads 5. On each sleeve 2 are rigidly fixed plates (ribs) 6, forming a cone with apex at the place of attachment to the sleeve 2. The plates (ribs) 6 are interconnected by elastic membranes 7, which are made of oil-resistant and afryktsionny material and have holes 8 at the base of the cone and hole 9 at its vertices (except the lower stake) a). The fastening antennae 10 are fixed above the upper cone. The lower cone is made removable, fixedly fixed on the rod 4 with a pin 11. Elastic membranes 7 on the lower cone have holes 9 at the apex. In the handle 1 there is a cover-case 12 made of an elastic material.

To extend the depth of sampling, the tube is used to extend the extension tube 3. At the same time, it serves as a canister cover for the working part of the sampler in the transport position and during storage.

The sampler works as follows.

By pressing the handle 1, all the sleeves 2 are moved downwards, in such a way the pr-sampler is immersed in the embankment of the analyzed material under investigation to a predetermined depth. To increase this depth between the handle 1 and the sleeve 2, an extension tube 3 is used. Immersion of the sampler under the action of bulk material of the wall of the cone-shaped grippers, consisting of plates 6 and membranes 7, and the turner tendrils 10 are pressed to the rod 4, reducing the back

the river section of the sampler and thereby reducing the effort to dive it.

When removing the sampler, lift the handle 1, connected (including through the extension tube) with the upper sleeve 2, on which the trocate antennae 10 are fixed. They loosen the Fopox loose material, and the bend hails 5 transmits the lifting force from the upper bushing to the next one, at which lifting the upper cone-shaped grip consisting of ribs 6 and membranes 7 is wedged and filled with the analyzed material, then the force is transferred to the next bushing - and the next grip is filled, and so on to the lower cone-shaped grip but. Thus, the filling of the sampler occurs during its upward movement.

It should be noted that substantial spontaneous separation (self-sorting) of the material into fractions can occur in the embankment; therefore, an additional factor for leveling the representativeness of the sample are the holes 8 on the membranes 7 (at the bases of the cones), through which the excess fines fraction goes.

In order to pour out the extracted sample of fine-flowing material, a lower cone is disconnected from the sampler, the sleeve 2 of which is fixed on the rod 4 with a pin 11. The bulk material is ejected from all conical; grips through holes 9 at the top of the cones. If the material is difficult loose, the sample is poured through the upper open part of the cone-shaped grippers into the elastic case-collection 12, which is previously put on the working part of the sampler extracted from the embankment.
