SU61316A1 - A device for taking an average grain sample through the holes in the bottom edge of the drain pipe - Google Patents

Description

The most important condition for the proper setting of production control and accounting is the proper organization of the selection of a true average sample of the processed raw material. It should be noted that the existing methods for the selection of grain raw materials for analysis do not provide a valid average sample. As a result, the question of developing a sampler that ensures the selection of a true average sample of the processed raw material is highly relevant in the matter of controlling and recording production.

The proposed device with the use of a conventional box with an inlet slider and a tipping bale with a counterweight, attached to the bottom edge of the drain pipe, is intended for continuous automatic sampling of grain, as well as other bulk materials.

For sampling at certain time intervals, the bucket of the proposed device is divided into two halves, which are alternately automatically filled with grain by means of a tray, rockingly installed under the receiving funnel and equipped with a shank that interacts with an emphasis on the bucket. One of the sides of the scoop serves to dump the grain that has entered from the funnel to the sampler, and the other is intended to discharge the grain back through the chute to the sewer.

FIG. 1 shows a vertical section of an instrument for taking an average grain sample through an opening in the bottom edge of the drain; in fig. 2 is the same horizontal incision along A-A; in fig. 3 - also, a front view with a partial cut.

The device for sampling an average grain sample consists of a flat base / and a worm-like casing 2 with a door 7 and a funnel 3 welded to it. The base / has two cuts, from which the upper serves to catch and the lower to discard the product. The funnel 5 is equipped with a regulating throttle valve 4 and a distribution chute of the section “Viutri” of the casing 2 is mounted on center bolts 17 and a swinging double-sided wiper 10 with a moving over

threaded rod 12 counterweight /, serving to control the degree of filling of the bucket 10.

From the bottom of the casing 2 there is a chute for returning the product to the chute and bell for full or partial withdrawal of the product. Klapaiom 21 regulates the degree of selection through the pNSTrub. The device is installed on the bottom bar and in any place of the sewer.

A loose grain pipe or other product, a passage along base 1, partially enters a funnel 3, along which it is directed through a distribution tray // into one or the other half of a two-sided: ks1 10. the equilibrium, tilted, pours the accumulated product alternately either into the chute for return to the chute or into the socket for sampling. The outlets of the product to be taken can be directed through the socket back into the drain through valve 21. The transfer tray 11 is transferred to one or the other side of the bucket by an abutment 20, which interacts when the bucket tilts with the shank 11 of the tray 11.

The auto-adjusting sampler is automatically activated at the moment when the product appears in estrus.

Subject invention

Claims (2)

1. An instrument for taking an average grain sample through the holes in the bottom edge of the drain pipe, made in the form of a box with an inlet gate equipped with a tipping bucket with a counterweight, characterized in that for sampling at certain time intervals, the bucket is divided into two halves, one of which serves to dump the grain from the funnel into the sampler, and the other to discharge the grain back into the sewer through the chute. 2. A device for making an apparatus according to claim 1, characterized in that for successive automatic filling of both halves of the bucket with grain, a tray is provided rocking-mounted under the device's receiving funnel, equipped with a shank interacting with an abutment on the bucket.
