Abstract
An automatic closing spout for a combine grain auger which opens when there is grain passing through the auger comprising a pivotally mounted collecting bucket attached adjacent the discharge opening of the auger with counterweighted arms extending outwardly from the collecting bucket to hold the bucket in a closed position, but insufficient when the bucket is full of grain from dumping and allowing grain to discharge from the auger housing and including a secondary closing means in the form of a permanent magnet which holds the collecting bucket in its closed position to prevent premature discharge therefrom.
Claims10
A grain auger closing spout for use on a combine auger housing which automatically opens when the auger is running and closes when the auger stops, comprising:
- a collecting bucket including side walls, slanted bottom and a back wall;
- flexible seal means forming an extension of the back wall to seal the collecting bucket against the auger housing in the closed position;
- a pair of mounting brackets attached to the auger housing;
- pivot means attaching the collecting bucket to the mounting brackets, one mounted on each side of the auger housing;
- and
- counterweight means carried on arms attached to the bucket extending away from the bucket and pivot means tending to pivot the bucket upward to its closed position when the bucket is empty but insufficient when the bucket is full from pivoting downward to dump the contained grain in its open discharge position.
