Abstract

A bubble-up auger assembly for an agricultural vehicle includes an auger at least partially surrounded by an outer tube. A bracket is configured to be non-rotatably connected to a rockershaft of the agricultural vehicle for rotation about a first axis. A slide rod is connected to the outer tube and the bracket. The slide rod is configured to cause the auger to move between a raised position and a lowered position in response to rotation of the bracket. In the lowered position of the auger, an axis of rotation of the auger is oriented oblique to the first axis.

First claim

What is claimed is:

1 . A bubble-up auger assembly for associated with an agricultural vehicle, the bubble-up auger assembly comprising:
an outer tube having a mount attached thereto; an auger at least partially surrounded by the outer tube, the auger having an axis of rotation; a bracket being non-rotatably connectable to a rockershaft of the agricultural vehicle for rotation about a first axis; and a slide rod connected to the bracket and slidably connected to the mount of the outer tube, wherein one end of the slide rod forms a ball, the slide rod causing the auger to move between a raised position and a lowered position in response to rotation of the bracket; and a pin, which has an opening passing therethrough, being connected to the mount; wherein, in the raised position of the auger, the ball is seated against the opening of the pin, wherein, in the lowered position of the auger, the slide rod is positioned through the opening of the pin and the ball is spaced apart from the opening of the pin, and wherein, in the lowered position of the auger, the axis of rotation of the auger is oriented oblique to the first axis.

2 . The bubble-up auger assembly of claim 1 , wherein the first axis is an axis of rotation of the rockershaft.

3 . The bubble-up auger assembly of claim 1 , wherein the slide rod is also connected to the bracket by a second pin.

4 . A grain tank assembly for the agricultural vehicle comprising a grain tank and the bubble-up auger assembly of claim 1 .

5 . The grain tank assembly of claim 4 , further comprising the rockershaft being rotatably connected with respect to the grain tank about the first axis.

6 . The grain tank assembly of claim 5 , further comprising a grain tank cover being movably mounted to the grain tank between an open position and a closed position, and a linkage connected to both the grain tank cover and the rockershaft such that rotation of the grain tank cover causes movement of the linkage which causes rotation of the rockershaft.

7 . The grain tank assembly of claim 6 , wherein in the closed position of the grain tank cover, the auger is positioned in the lowered position, and in the open position of the grain tank cover, the auger is positioned in the raised position.

8 . The grain tank assembly of claim 6 , wherein the grain tank cover is coupled to the grain tank by a hinge that is separate from the linkage.

9 . An agricultural harvester comprising the grain tank assembly of claim 4 .

10 . A bubble-up auger assembly associated with an agricultural vehicle, the bubble-up auger assembly comprising:
an auger at least partially surrounded by an outer tube, the auger having an axis of rotation; a bracket being non-rotatably connectable to a rockershaft of the agricultural vehicle for rotation about a first axis; and a slide rod connected to the outer tube and the bracket, the slide rod causing the auger to move between a raised position and a lowered position in response to rotation of the bracket; wherein the slide rod is connected to the outer tube by a first pin, the slide rod is connected to the bracket by a second pin, wherein the first and second pins are oriented oblique to the first axis, and wherein, in the lowered position of the auger, the axis of rotation of the auger is oriented oblique to the first axis.

11 . A grain tank assembly for the agricultural vehicle comprising a grain tank and the bubble-up auger assembly of claim 10 .

12 . The grain tank assembly of claim 11 , further comprising the rockershaft being rotatably connected with respect to the grain tank about the first axis.

13 . The grain tank assembly of claim 12 , further comprising a grain tank cover being movably mounted to the grain tank between an open position and a closed position, and a linkage connected to both the grain tank cover and the rockershaft such that rotation of the grain tank cover causes movement of the linkage which causes rotation of the rockershaft.

14 . The grain tank assembly of claim 13 , wherein in the closed position of the grain tank cover, the auger is positioned in the lowered position, and in the open position of the grain tank cover, the auger is positioned in the raised position.

15 . The grain tank assembly of claim 13 , wherein the grain tank cover is coupled to the grain tank by a hinge separate from the linkage.

16 . An agricultural harvester comprising the grain tank assembly of claim 11 .
