APPARATUS FOR DETERMINING GRAIN COMBINE LOSSES Russian patent published in 1999 - IPC

FIELD: agriculture. SUBSTANCE: apparatus has vessel, partition wall mounted within vessel, sleeve positioned for rotation about axis of revolution till abutment against one of side walls. Apparatus is adapted to be positioned in spacings and movable partition wall is deflected clockwise till abutment against vessel side wall. Upon passage of header and gathering of lost grain and spikes behind header, partition wall is turned counterclockwise to close first vessel half with gathered material and open second free half. Combine grain losses behind thresher are gathered into second half of vessel. Such construction allows separate evaluation of grain losses behind header and thresher to be performed. EFFECT: increased efficiency and reliable evaluation of combine operation. 2 cl, 4 dwg
