Reclaimer having a drum chamber door control system

A method of operating a reclaimer having a frame supported by a plurality of wheels connected to the frame by a plurality of legs, a milling drum attached to the frame, and a drum chamber surrounding the milling drum, the method comprising:

• adjusting a height of the milling drum relative to the frame;
• rotating the milling drum to cut a ground surface;
• accumulating and mixing material cut by the milling drum in the drum chamber;
• propelling the wheels and allowing the material to exit the drum chamber from under a movable door of the drum chamber;
• determining, using a controller, a target position of the movable door based on a machine characteristic and a predetermined gradation of the material exiting from the drum chamber;
• and
• selectively adjusting an actuator associated with the movable door based on the determined target position.

A reclaimer, comprising:

• a frame;
• a left front wheel disposed connected to a front end of the frame;
• a right front wheel disposed connected to the front end and spaced apart from the left front wheel;
• a left rear wheel disposed connected to a rear end of the frame;
• a right rear wheel disposed connected to the rear end and spaced apart from the left rear wheel;
• a left arm pivotably connected to the frame and extending from the frame;
• a right arm pivotably connected to the frame and extending from the frame;
• a cross tube connecting the left arm and the right arm;
• at least one arm actuator connecting the frame and the cross tube;
• a milling drum rotatably connected to free ends of the left and right arms;
• a drum chamber configured to enclose the milling drum, the drum chamber extending along a width of the frame;
• a movable rear door attached to the drum chamber and extending along the width of the frame;
• a movable front door attached to the drum chamber and extending along the width of the frame;
• an engine configured to rotate the milling drum and propel the wheels such that material exits the drum chamber from under the rear door;
• and
• a controller configured to:
• determine a target position of at least one of the rear door and the front door based on a machine characteristic and a predetermined gradation for the material exiting from the drum chamber;
• and
• selectively adjust an actuator associated with at least one of the rear door and the front door based on the determined target position.
