A shaker for a mobile crop harvester comprises an hydraulic motor directly driving the tined harvester brushes and a valve to control the motor output to provide a desired oscillatory motion to the brushes

摘要

Crop harvester(10)comprises mobile frame mounted tined harvesting brushes(16:17)directly driven by hydraulic motor(23)where the motor speed amplitude and amplitude rate can be operator controlled by control valve(32)positioned between the motor and hydraulic pump(29) An Independent claim is included for a crop harvester equipped with the directly driven shaker Preferred features;The brush drive can alternatively be electric or pneumatic motors with associated control devices the brushes sized to internally receive the drive motor which has a case mounted inertial member and resilient centering device
