Abstract
An agricultural furrow opening system having a hybrid single-disk, double-disk opener is disclosed including a swing-arm, a primary disk, and a deflecting disk. The primary disk is coupled to a distal end of the swing-arm and configured to rotate about a first axis. The primary disk is rolled about a direction of travel at a first oblique angle θP and yawed about a vertical direction at a second oblique angle ζP. The deflecting disk is coupled to the distal end of the swing-arm and configured to rotate about a second axis. The deflecting disk is rolled about the direction of travel at a third oblique angle θD and yawed about the vertical direction at a fourth oblique angle ζD. The first oblique angle θP is between the vertical direction and the third oblique angle θD.
Claims20
An agricultural furrow opening system comprising:
- a towing frame for being coupled to a tractor, the towing frame being configured to move in the direction of travel along a surface of a field;
- an attachment frame adapted to be rigidly connected to the towing frame;
- and
- a swing-arm having a distal end and a proximal end, the proximal end coupled to the attachment frame;
- a primary disk coupled to the distal end of the swing-arm and configured to rotate about a first axis, the primary disk being rolled about the direction of travel at a first oblique angle θP and yawed about a vertical direction at a second oblique angle ζP, the vertical direction being generally perpendicular to the direction of travel and extending upwards from the surface of the field;
- and
- a deflecting disk coupled to the distal end of the swing-arm and configured to rotate about a second axis, the deflecting disk being rolled about the direction of travel at a third oblique angle θD and yawed about the vertical direction at a fourth oblique angle ζD, the first oblique angle θP being disposed between the vertical direction and the third oblique angle θD.
An agricultural furrow opening system comprising:
- a towing frame;
- a swing-arm having a distal end and a proximal end, the proximal end being coupled to the towing frame;
- a housing coupled to the distal end of the swing-arm, the housing including
- an outer surface having a seat configured to receive at least one outer bearing, the at least one outer bearing defining a first axis of rotation, and
- an inner bore configured to receive a spindle, the spindle disposed within a perimeter of the seat, the spindle defining a second axis of rotation different than the first axis of rotation;
- a primary disk coupled to the distal end of the swing-arm and configured to rotate about the first axis of rotation;
- and
- a deflecting disk coupled to the distal end of the swing-arm and configured to rotate about the second axis of rotation.
An agricultural furrow opening system comprising:
- a towing frame for being coupled to a tractor, the towing frame being configured to move in a direction of travel defining horizontal;
- an attachment frame adapted to be rigidly connected to the towing frame;
- and
- a swing-arm having a distal end and a proximal end, the proximal end coupled to the attachment frame;
- a primary disk coupled to the distal end of the swing-arm and configured to rotate about a first axis;
- a deflecting disk coupled to the distal end of the swing-arm and configured to rotate about a second axis, the second axis being different than the first axis;
- and
- a mounting assembly disposed at the distal end of the swing-arm, the mounting assembly configured to operatively engage the primary disk and the secondary disk such that one of the primary disk and the secondary disk is disposed between the swing-arm and the other of the primary disk and the secondary disk.
