Abstract
A harvesting machine, especially a self-propelled pick-up chopper for picking up and chopping corn, wilted grass, green feed and similar harvested produce, including an ejection elbow arranged after pulling in and chopping devices for transferring harvested produce to a loading space of an accompanying vehicle. In order to free the operator of the harvesting machine from the burden of the cumbersome positioning work after each change in the direction of travel, the ejection elbow can be swiveled by a motor controlled by a control device from a first operating position into a second operating position which corresponds to the first operating position of the ejection elbow mirrored in the vertical median plane.
Claims28
A harvesting machine, comprising:
- an ejection elbow arranged downstream from pulling in and chopping devices and to transfer the harvested material to a loading space of an accompanying vehicle;
- a motor for swiveling the ejection elbow;
- and
- a control device arranged to automatically control the motor to swivel the ejection elbow from a first operating position in to a second pre-programmable operating position, the second operating position corresponding to the first operating position of the ejection elbow mirrored at the vertical, longitudinal, median plane of the harvesting machine,
- the control device comprising a zero position sensor, an angle measuring counter and a control unit.
In a harvesting machine including a material working device for processing agricultural material, an ejection elbow through which the processed material is adapted to pass and a motor for rotating said ejection elbow, the improvement comprising
- a control unit coupled to said ejection elbow and said motor and arranged to automatically control rotation of said ejection elbow via said motor such that said ejection elbow is rotatable between a first operating position and a second pre-determined operating position,
- said first and second operating positions being opposite positions relative to a vertical, longitudinal median plane of the harvesting machine,
- said control unit comprising a zero position sensor for determining a zero position of said ejection elbow and an angle measuring counter for measuring rotation of said ejection elbow.
A harvesting machine comprising:
- a material working device for processing agricultural material;
- an ejection elbow through which processed material from said material working device is adapted to pass;
- rotation means for rotating said ejection elbow;
- and
- control means for automatically controlling rotation of said ejection elbow via said rotation means such that said ejection elbow is rotatable between a first operating position and a second predetermined operating position,
- said control means comprising position determining means for determining a zero position of said ejection elbow and angle measuring means for measuring angular rotation of said ejection elbow.
A method for controlling rotation of an ejection elbow of a harvesting machine through which agricultural material passes from a first operating position to a second predetermined operating position;
- comprising the steps of:
- mounting the ejection elbow on a rotatable turntable;
- marking the turntable with a zero position mark;
- starting rotation of the turntable;
- determining when the zero position mark passes a fixed location;
- determining a first angle of rotation of the turntable from the first operating position to the position at which the zero position mark passes the fixed location;
- calculating a second angle of rotation of the turntable from the position at which the zero position marks passes the fixed location to the second operating position based on the first angle of rotation;
- and
- stopping rotation of the turntable after the turntable has been rotated over the second angle of rotation such that the turntable is positioned in the second operating position when rotation of the turntable stops.
