Abstract

A discharge spout arrangement of an agricultural harvesting machine through which harvested crop processed by the harvesting machine can be transported to a transport vehicle. The discharge spout arrangement includes a first spout element connected with the harvesting machine. A second spout element is mounted to and defines an extension the first spout element. The second spout element is slidably movable between fully retracted and extended positions respectively wherein a discharge end of the second spout element is spaced a minimum and a maximum distance from a discharge end of said first spout element.

Claims

1. In an agricultural harvesting machine including a discharge spout arrangement through which harvested crop processed by the harvesting machine can be transported to a transport vehicle, the improvement comprising:

said discharge spout arrangement including first and second separate spout elements each having first and second ends;

said first end of said first spout element end being connected with the harvesting machine;

said second spout element being provided with at least one arm extending beyond said first end of said second spout element toward said first spout element;

a roll being mounted to said arm and engaged with said first spout element;

said second spout element being mounted to said first spout element for sliding along said first spout element and forming an extension of said first spout element which is movable between a fully retracted position, wherein said second end of said second spout element is spaced a minimum distance from said second end of said first spout element and a fully extended position, wherein said second end of said second spout element is spaced a maximum distance from said second end of said first spout element; and

said roll rolling along said first spout element during movement of said second spout element relative to said first spout element.

2. The agricultural harvesting machine, as defined in claim 1, wherein said first spout element includes at least one plastic bearing element extending along a length dimension of said first spout element;

and said second spout element being mounted for sliding along said at least one plastic bearing element.

3. The agricultural harvester, as defined in claim 1, wherein said at least one arm is mounted to one side of said second spout element;

a second arm extending parallel to said at least one arm and being mounted to an opposite side of said second spout element from said one side; and

a second roll being mounted to said second arm and engaging said first spout element.
