Definitions

  • the onboard grain dryer for a combine harvester uses the hot air from the engine compartment to dry down the moisture percentage of the grain being harvested. This all starts in the engine compartment where there is a large turbine fan mounted next to the engine. The engine heats the air around it as it runs and the turbine fan blows the heated air into two, eight inch diameter, circular ducts that carry the air out of the engine compartment and into the grain bin where the drying will take place.
  • the ducts from the fan channel the hot air into a box that has no bottom to it and has vents on the inside to evenly distribute the hot air into the grain.

Abstract

A combine harvester with a drying mechanism from which heated air from the engine compartment of the combine is blown out with a large turbine fan and channeled into ducts that lead the heated air into the grain bin and into a mechanism that distributes that heated air evenly through the grain.

Description

ONBOARD GRAIN DRYER FOR A COMBINE HARVESTER
DESCRIPTION
The onboard grain dryer for a combine harvester uses the hot air from the engine compartment to dry down the moisture percentage of the grain being harvested. This all starts in the engine compartment where there is a large turbine fan mounted next to the engine. The engine heats the air around it as it runs and the turbine fan blows the heated air into two, eight inch diameter, circular ducts that carry the air out of the engine compartment and into the grain bin where the drying will take place. The ducts from the fan channel the hot air into a box that has no bottom to it and has vents on the inside to evenly distribute the hot air into the grain. There is also a smaller duct attached to one of the two larger ducts that channels some hot air into the clean grain auger to insure all grain gets dried evenly.

Claims

Claims The invention claimed is:
1. A combine harvester with a drying mechanism from which hot air is blown out of the engine compartment of the combine with a large turbine fan and channeled into ducts that lead to the grain bin where there is a mechanism for distributing the hot air evenly into the grain and ultimately drying the grain down a few percent moisture content.
2. The combine harvester according to claim 1, characterized in that the mechanism for distributing the heated air into the grain contains small vents directly below where the ducts attach to the mechanism to distribute the air evenly through the grain in the grain bin of the combine harvester to insure even dry down of the grain.
