UNIVERSAL GRAIN- AND SEED-CLEANING LINE Russian patent published in 2012 - IPC B07B9/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural mechanical engineering and is designed for post-harvesting treatment of seeds of agricultural crops. Universal grain- and seed-cleaning line includes series-connected receiving hopper, a loading conveyor, a loading bucket line, the machine of primary cleaning, an intermediate bucket line, a sifting cylinder unit, a final bucket line, a pneumatic assorting table. The storage hopper and grain pipes connecting the loading conveyor with a lower head of the bucket line, the upper head of the loading bucket line - with the input of the machine of primary cleaning, the output of the machine of primary treatment - with the lower head of the intermediate bucket line, the upper head of the intermediate bucket line through the first changeover valve - with the input of the sifting cylinder unit, upper head of the final bucket line - with the pneumatic assorting table. The line additionally contains a seed-cleaning wind-sieve machine mounted in front of the pneumatic assorting table. Loading elevators mounted at intermediate and final bucket line, an intermediate hopper mounted under the sifting cylinder unit, mobile containers mounted at the intermediate and storage hoppers and at outputs of the pneumatic assorting table. The second changeover valve installed in the grain pipe connecting the upper head of the final bucket line to input of the pneumatic assorting table, grain pipes connecting the first changeover valve - with the input of the seed-cleaning wind-sieve machine, the output of the seed-cleaning wind-sieve machine - with the lower head of the final bucket line, the second changeover valve - with the storage hopper, and the grain pipe connecting the loading elevator mounted at the intermediate bucket line - with its lower head and the grain pipe connecting the loading elevator installed at the final bucket line - with its lower head.

EFFECT: reduced traumatising of seeds, increase of efficiency of seed cleaning, and simplification of management of the line.
