GRAIN SAMPLE CLEANING SEPARATOR FOR EVALUATING THE WORK OF HARVESTING MACHINES Russian patent published in 2021 - IPC B07B9/00 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to means of assessing the quality of work of harvesting machines. A separator for cleaning grain samples when determining grain losses for evaluating the operation of harvesting machines is proposed, which is made in the form of three collapsible sections, batteries are placed in the lower section, a fan and a speed controller are installed in the central section, located in the control unit located on the section body, and a sieve is placed in the upper section. Also, the upper section is equipped with a sieve holder, a stirrer and a lock with an axis on which the sieve and the stirrer are mounted, and the outer side of the upper section body is equipped with a level rigidly fixed on the handle. The central section is equipped with a fan holder, a bottom and a handle for transporting the separator, fixed on the outside. The lower one is a battery lock and a limiter. In the upper part of the bodies of the lower and middle sections, there are grooves for fixing adjacent sections, and in the lower part of the adjacent sections there are reciprocal guides.

EFFECT: invention provides efficiency when used.
