Description

In order to improve the instrument for taking average grain samples, described in the main jV patent. 10641, in which the grain, nada from the upper funnel but alternately to the lower ones, is divided by each successive funnel into two unequal parts, of which most of it is removed, the smaller one is the middle nrob.

In the proposed apparatus, intercalated and placed in the lower funnels of the cylinder with slots for sieving the sample are applied.

In the drawing fng. 1 shows a vertical section of the tool, FIG. 2 - horizontal it. section, fig. 3 and 4 - metal cylinders in expanded form.

The proposed form of the device for taking a grain sample consists of storey funnels B, A for receiving grain and cones r, D fixed on corner racks K. Two of the later funnels are equipped with partitions that divide them Ha jsoceMb branches, four of which are smaller and .four more about; In the center of these funnels are located concentrically mounted cylinders O, L, PZ yoih O cylinders are equipped with eight openings, and, cylinders L are four. A vessel M is placed under the opening of the lower funnel to hold the sample. The funnels are fixed in fixed rings C, fitted with screws i), intended to be mounted with holes against cones. To rotate the cylinders L with de. releasing the grain grown after taking the sample in the wide compartments of the funnels A serves as a handle jp.

Prob. the grain is poured into the funnel, B ъ falls through the central hole in the cone r and further, in the lower same funnel. In with the cone git. d., the stack from the hole a of the last funnel B to the first cone B, from which it rolls into the funnel A, from where from its narrow compartments C / g a part of the incoming grain, through the openings of both cylinders outer O and inner L (Fig. 3 and 4) and the central "goes to the second cone jB- and further to the lower funnel L, also divided into narrow and wide compartments. With that, the grain from the narrow compartments is not delayed, through the longitudinal holes of the copper cylinders (О v. L) and through the central hole, the last funnel A enters the vessel F

The grain flows in a continuous stream from the springs B through the openings of the narrow compartments of both funnels into the vessel M, because the longitudinal openings of the compartments of the funnels A (in the outer cylinder) and the same openings of the inner cylinder leading to the grain from the funnels A are open and match At the same time, the openings of the wide t of the funnels of the funnels in the outer cylinder O are closed by the blind parts of the walls of the inner cylinder, the lidder, and the large part (/ g) of the entire nodular grain remains in the wide compartments of the funnels J; after,

From the sample, it is released, as a test, into any vessel.

 The subject of the patent.

The design of the device described in patent J 10641 is different, and using external O and internal L cylinders located in A funnels and equipped with prostheses for screening the sample and with reamers p for turning the inner cylinder X to align the cuts of both cylinders.
