Description

A device for separating grain mixtures

The utility model relates to agricultural machinery, in particular, to air-sieve-and-trie grain cleaning machines and can be used in food industry and in agriculture for cleaning seeds of agricultural crops

Known air-sieve-triter grain cleaning machine containing a loading hopper, an air-cleaning part with a fan, sediment chamber, sieve mill with upper and lower sieve, sieve cleaning mechanism,

Trier block with puppet and oat-bore cylinders, elevator.

The disadvantage of the machine is the impossibility of fractional seed cleaning in triremes. ToK descending from the lower sieve is connected to the lower elevator head, which supplies the entire stream of seeds cleaned on the sieve to the triera. This leads to a decrease in the quality of separation of the grain mixture / Machines for post-harvest grain processing / B. SoKnin, I, Vv Gorbachev, A, A, Terekhin, V, M. Soloviev.- M .: Agropromizdat, 1967, p.40 /.

The closest in technical essence and the achieved positive effect is an air-sieve-screening machine containing a loading hopper, an air-cleaning part with a fan and a sediment chamber, a sieve mill with upper and lower sieves, a sieve cleaning mechanism, a trie block with a doll and oat-bale cylinders, a noriya / Machine K543 Super Plus. Prospectus of the company Yetkus attached to the application.

impurities, the length of which is comparable with this sign of seeds of the main culture. The decrease in the quality of cleaning is explained by the fact that the seed stream purified on the sieve mill comes from the lower sieve, without preliminary fractioning into the lower one, for example, a doll cylinder for separating short impurities. Then it is fed by a noriya into the oat-bore cylinder to separate long impurities

The technical result of the utility model is to improve the quality of cleaning.

The essence of the utility model consists in installing between the upper and lower sieves an additional sieve, similar to which about. connects through the tray to the lower cylinder of the additional trimera block.

The installation of an additional sieve leads to a preliminary separation of the entire grain flow, freed from large impurities during cleaning on the short and upper sieves, into two fractions, for example, according to the thickness of the sieve with oblong holes or the width of the sieve with round holes or a complex of physical and mechanical properties on the sieve with round holes, the diameter of which is greater than the width of the seeds of the main culture and having an unperforated surface on the initial part. Separate purification of these fractions / after treatment with an off-air stream / two pairs of trimers / existing and additionally established / with di-controlled selection of cells leads to an increase in the completeness of the separation of impurities. This improves the quality of seed cleaning.

The device consists of; receiving hopper I, air cleaning part 2 with fan 3, sediment chamber 4 of the sieve mill 5 with short 6 upper 7, lower 8 and middle 9 sieves, inlet part, consisting of two pairs of 10, P cylinders, located one below the other, double-flow elevator 12р trays 13 and I4j 15 and 16, 17 and 18, drive mechanisms of the working bodies of the machine 19,

The device operates as follows Grain MIXTURE after cleaning, for example, in gravity-type separators, is fed into the hopper I from which it enters through the first suction channel of the air-cleaning part 2 and a short sieve 6 to the upper sieve 7. Sieve 6 and 7 in this case, large impurities are separated .

The passage of the sieve 7 enters the sieve 9, which separates the incoming components into two fractions; the feed fraction along the tray 13 enters the lower, for example, a puppet cylinder of the first pair of 10 triers; and the passage, passing through the sieve 6 separating small impurities, is sent by tray 1 to the same. exchange cylinder of the second pair of II triers. Grain purified from short impurities is sent to the noriya 12 by trays 17 and 16, which feeds it in separate streams along trays 15 and 16 to the upper, for example, oatmeal cylinders of the first 10 and second P of the trie blocks.

The proposed device, in contrast to the prototype, allows fractional purification of seeds, which increases their quality
