Floating floor assembly of a header

A header for an agricultural vehicle, comprising:

• a frame;
• an auger having a longitudinal axis the auger rotatably connected to the frame;
• and
• a floor assembly connected to the frame and positioned underneath the auger, the floor assembly comprising:
• a floating floor comprising a stationary lower floor portion and a movable upper floor portion connected to the lower floor portion, and the upper floor portion is configured for contacting a crop material which applies a force onto the upper floor portion, the upper floor portion including a front end and a back end, the front end forward of the back end with reference to direction of forward operative travel of the header;
• and
• at least one biasing member connected to the upper floor portion rearward of the longitudinal axis of the auger with reference to direction of forward operative travel of the header and configured for biasing the upper floor portion at the connection so that the upper floor portion moves in response to the force applied by the crop material, of the front end and the back end of the upper floor portion only the back end is connected to both the lower floor portion and the at least one biasing member.

A method for varying a crop conveying ability of a header for an agricultural vehicle, the header comprises a frame and an auger having a longitudinal axis, comprising:

• providing a floor assembly configured for being connected to the frame and positioned underneath the auger, the floor assembly comprising a floating floor comprising a stationary lower floor portion and a movable upper floor portion connected to the lower floor portion, and the upper floor portion is configured for contacting a crop material which applies a force onto the upper floor portion, the upper floor portion including a front end and a back end, the front end forward of the back end with reference to direction of forward operative travel of the header, and at least one biasing member connected to the upper floor portion rearward of the longitudinal axis of the auger with reference to direction of forward operative travel of the header, of the front end and the back end of the upper floor portion only the back end is connected to both the lower floor portion and the at least one biasing member;
• and
• biasing the upper floor portion, by the at least one biasing member at the connection, so that the upper floor portion moves in response to the force applied by the crop material, and the upper floor portion moves upwardly, closer to the auger, in response to a lighter force applied by the crop material, and the upper floor portion moves downwardly, farther away from the auger, in response to a heavier force applied by the crop material.
