Description

The invention relates to a grader-sorting machine with a sieve machine, mounted above the fan and used to sort the grain before it enters under the stream of air. In the proposed grading, the cavity of its machine is divided by partitions into chambers for separate sorting according to the weight of grain.

In the schematic drawing of FIG. 1 is a front view of the sorting mechanism; FIG. 2 - her back view; FIG. 3 is a longitudinal section of a sieve mill; FIG. 4 is a side view; FIG. 5 is a longitudinal section of p, o chamber 2; Fig b - the cut through the chamber 3; FIG. 7 is a section through the chamber 4.

In the proposed grading-sorting, the grains are sorted by size on a sieve mill 11, consisting of pt sieves 17 - 21, prior to the air stream entering into action. Separate grain fractions, obtained on sieves by sorting by size, are directed using a system of pitched planks 7 to different chambers 1, 2, 3

or 4 and sorted by weight during the passage to these chambers. The possibility of adjusting the air jet supplied by the fan 22 is achieved in separate chambers with pvmoshi flaps 5.

From i-harnessed by weight, the grain enters the collecting boxes 12-16, of which it is discharged through the doors located from below or from the side.

The subject matter of the invention.

1.Wheel sorting with a sieve mill installed above the fan and intended for sorting the grain before it enters the air under the breeder, characterized in that, for the purpose of separate sorting by weight of sieve fractions of grain, its machine is divided by partitions 6 on the kagler 1, 2, o and 4.

2. In the case of sorting in paragraph 1, the use of valves 5, which are separate for each chamber, is intended for independent control of the air stream.
