Abstract:
A direct drive shaker head mounted for oscillatory rotating motion on a framework of mobile crop harvester used for harvesting above ground crops, comprisinga first crop engaging brush having and axial length and an axis of rotation, a first motor mounted to a first plate, said first motor providing a motor output directly connected to said first crop engaging brush to directly drive said first crop engaging brush about said axis of rotation, a second crop engaging brush having an axial length and an axis of rotation, a second motor mounted to a second plate, said second motor providing a motor output directly connected to said second crop engaging brush to directly drive said second crop engaging brush about said axis of rotation, a connecting member connecting said first plate to said second plate, said connecting member preventing the first motor and the second motor from rotating relative to one another, a device for transferring power from the framework of the mobile crop harvester to the first and second motors, and a controller controlling output from said first motor and from said second motor to provide oscillatory motion of said first crop engaging brush and said second crop engaging brush respectively about said axis of rotation of each crop engaging brush.
