SU368544A1 - DEVICE FOR DETERMINATION OF GRAIN WEATHER - Google Patents

Description

one

The invention relates to devices for determining the quality of grain, namely, devices for determining grain debris.

A similar device is known, containing a container for a grain sample, mounted vertically on a mesh base, a vibrator and a fan.

The proposed device allows speeding up the process of determining the clogging of the grain mass.

This is achieved by the fact that the capacitance consists of two sections, one of which enters inside the other, and the upper section is adapted for axial movement. A collection for litter can be attached to the upper section.

Pa drawing shows the basic scheme of the proposed instrument.

A device for determining grain debris contains a tank consisting of two sections 1 and 2 s. a mesh base 3, the section / entering the inside of section 2, which is axially displaced to which the collector 4 is attached for the weed; the vibrator 5 and the fan 6 with a chimney: and air damper 7.

The device works as follows.

In section 1, a sample of the grain mass is poured, which is the node by vibration and

upstream air flow is in a fluidized state. Particles with a specific gravity, weight equal to or somewhat greater than the proportion of the main culture particles, rise to the upper part of the layer. Particles with a low specific gravity of any size rise there too. Such a distribution is reached within 2-3 ltp. It is fixed along a clear boundary between the layer.

impurities and a layer of grain.

Thereafter, section 2 is lowered down until the upper edge of the crop is aligned with the boundary between the impurities and pure grain. This will cause impurities to be poured into the collection.

4. At the same time, the air flow rate in the layer remains unchanged, which is achieved with the help of the air damper 7.

Further lowering of section 2 is carried out until the main grain appears on the upper edge of the grain.
