Combine ground speed and drum speed automatic control
Abstract
Abstract A COMBINE HARVESTER THRESHER WITH DRIVEN GROUND WHEELS, A CROP-TREATING ASSEMBLY, AN ENGINE TO DRIVE THE GROUND WHEELS AND THE CROP-TREATING ASSEMBLY, AND CROP GATHERING MEANS WHICH INCLUDES AN ELEVATOR ASSEMBLY IN AN ELEVATOR HOUSING FOR CONVEYING CROP MATERIAL TO THE CROP-TREATING ASSEMBLY. THE DRIVE FOR THE DRIVEN GROUND WHEELS INCLUDES A VARIABLE V-BELT DRIVE. THE CROP-TREATING ASSEMBLY IS DRIVEN BY BELT DRIVES FROM THE ENGINE. WHEN AN EXCESSIVE AMOUNT OF CROP MATERIAL ENTERS THE ELEVATOR HOUSING, THE ELEVATOR ASSEMBLY IS DEFLECTED UPWARDLY CAUSING THE ELECTRICAL CONTACTS OF A SENOR TO MAKE CONTACT. THIS CAUSES CURRENT TO PASS THROUG A CIRCUIT AND TO ENERGIZE A PAIR OF SOLENOIDS. ON OF THE SOLENOIDS REDUCES THE GROUND SPEED OF THE MACHINE BY ACTUATING THE CONTROL FOR THE VARIABLE V-BELT DRIVE. THE OTHER SOLENOID SWITCHES THE TWO-STAGE GOVENOR ON THE ENGINE FROM ONE STAGE TO ANOTHER TO RUN THE CROP-TREATING ASSEMBLY AT A FASTER SPEED.
