CLEAN GRAIN SAMPLER FOR A COMBINE HARVESTER

摘要

In a self-propelled combine harvester, a grain sampling device is inserted in an opening in the common wall structure shared by the rear of the operator enclosure and the front of the grain tank. In the opening, a prism shaped receiving cup rocks about its bottom edge between a closed position in which the cup extends into the tank and the wall opening is sealed; an intermediate position in which grain is collected in the cup; and a third position in which the opening is again sealed and the cup extends into the operator enclosure, permitting extraction of the grain sample from the cup. A chute diverts a portion of the delivery of grain from the clean grain elevator to the sampling cup so that grain may be sampled at all states of filling of the grain tank.
