DEVICE TO DESTROY BRIDGING OF LOW-LOOSE GRAIN HEAP OF COMBINE HARVESTER HOPPER

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to the field of agricultural machine building and may be used designs of combine harvester hoppers. The device is installed in a hopper of a combine harvester, comprising a body with a ramp bottom and a discharge auger. The device, by means of a vibrator, makes reciprocal movements and comprises plates, which are transverse relative to heap displacement, to form windows for heap passage between their lower edges. The vibrator stem is hingedly connected to a stem, the other end of which is supported with a support wheel. Transverse plates that freely rotate around the axis are hingedly fixed along the whole length of the stem. The plates rotation is limited against rotation by an angle of more than 90° to the stem by rigidly fixed supports.;EFFECT: device tills the lower compacted layer of low-loose soil and sends it to a discharge auger, to prevent bridging and increase reliability of low-loose heap discharging process.;4 dwg
